Denitrification price subsidies will be introduced soon
It is reported that the implementation of denitrification price subsidies nationwide has entered a countdown. Denitrification price subsidies are about to be implemented nationwide
In the “Twelfth Five-Year Plan†Energy Saving and Emission Reduction Plan, the state clearly stipulates the “Twelve Five-Year†nitrogen oxide emission reduction targets. Among them, the thermal power industry requires a reduction in the emission of nitrogen oxides by 29%; by 2015, 400 million will be completed. The construction of denitrification facilities for coal-fired units in active kilowatts will be implemented in a low-nitrogen combustion technology for 70 million-kilowatt coal-fired units, and the denitration efficiency of coal-fired units will reach 75% or more.
Liu Bingjiang said that the construction of "beautiful China" looks at environmental protection. The state promotes energy conservation and environmental protection as a key industry in the “Twelfth Five-Year Planâ€. Among them, denitrification is an important part. According to the statistics of the Ministry of Environmental Protection, the total installed capacity of denitrification in the national thermal power industry will reach 200 million kilowatts by the end of this year. He disclosed that the implementation of denitrification price subsidies nationwide to enter the countdown, the thermal power plant on the denitrification device will be implemented according to the denitrification price.
For thermal power companies suffering from losses, the advancement of the denitrification process depends to a large extent on policy subsidies. A person in charge of the power company told reporters that the industry's estimated denitrification price subsidies will remain at 0.8 points, but this price does not alleviate the heavy pressure of thermal power plants, "a penny power plant days is relatively better, only reach 1.2 points to break even ."
The quality of the market "big cake" will be fined
During the “12th Five-Year Plan†period, there will be explosive growth in the power denitration industry, and the market capacity is expected to exceed 150 billion yuan. At the same time, the emission indexes of nitrogen oxides in cement, steel and other industries will gradually be included in the scope of supervision, and will be gradually launched during the “Twelfth Five-Year Plan†period. This part of the new market capacity may reach more than 60 billion Yuan. The market for new denitrification units will be 0.5 billion kilowatts per year between 2012 and 2014, and the SCR project market capacity may reach 68.94 billion yuan.
Liu Bingjiang pointed out that the denitrification “big cake†has been launched, which will drive the development of industrial equipment, catalyst manufacturing, and regenerative disposal. Faced with the strong demand for denitrification market, the catalyst market is also warming up. At present, there are more than 60 domestic denitrification catalyst manufacturers, including small companies, and some large-scale desulfurization companies have begun to set foot in the denitrification industry. "Early next year, the Ministry of Environmental Protection will send 300 people to check the emission reduction of environmental pollutants, with an emphasis on the quality and operation of denitrification. The denitrification industry is 'quality first', and companies that fail to achieve quality will be named and punished."
SCR Denitrification Catalyst to Realize Localization of the Whole Industrial Chain
“There are many technical problems in the denitrification catalyst industry and it is necessary for the industry to solve them together.†At the meeting, Liu Bingjiang fully affirmed the strategic alliance for technological innovation in flue gas denitrification industry (abbreviated as “the coalitionâ€).
Since its formation in 2010, the alliance has actively undertaken scientific and technological projects such as the National Science and Technology Support Plan and the National 863 Plan, and has conducted joint development of new technologies and common key technologies. The governing units of the alliance are market-oriented, combined with China's new standards for atmospheric emissions, and carried out technological and technological innovations, which promoted the upgrading of the overall technology of the denitrification industry chain.
Among them, the only domestic certified denitrification catalyst of China Power Investment Yuanda Environmental Protection Co., Ltd. has been recognized by 56 countries in the world. The National 863 Program “High Efficiency and Low Cost Coal Combustion†jointly submitted by the company, Beijing Guodian Longyuan Environmental Protection Engineering Co., Ltd., Institute of Process Engineering of the Chinese Academy of Sciences, Tsinghua University, Zhejiang University, Chongqing University, and China National Institute of Standardization. "Development and Demonstration of Power Plant Flue Gas SCR DeNOx Catalyst" project, selecting the key raw material of titanium dioxide as denitration catalyst as a breakthrough, developing localized, high-efficiency and low-cost honeycomb catalysts, and developing a denitration catalyst suitable for a wide temperature range and its production Technology, through the integrated integration of technologies, conducts industrial application and engineering demonstration in large-scale power station boilers, realizes the localization of the overall industrial chain of SCR denitrification catalysts, and raises the level of China's environmental protection industry.
According to the national needs for energy conservation and emission reduction, the SCR denitrification catalyst market is about to start large-scale. It is expected that the denitrification catalyst demand will reach 500,000 m3 from 2010 to 2020. The use of self-titanium-tungsten powder can save costs about 2.2 billion yuan, wide-temperature catalyst promotion, compared to the existing medium-temperature commercial catalyst, the cost reduction of about 20%, emission reduction NOx about 17 million tons, reduce economic losses of 27 billion yuan.
With the evolution of the countdown, thermal power plants will implement the denitrification equipment according to the relevant electricity price subsidy policy.
Weak cables refer to cables used for security communications, electrical equipment, and related weak current transmission applications.
Wire and cable refers to materials used for power, communications, and related transmission purposes. "Wire" and "cable" do not have strict boundaries. Usually, the product with a small number of cores, a small product diameter, and a simple structure is called a wire. A wire without insulation is called a bare wire. Others are called cables. A conductor with a larger cross-sectional area (greater than 6 mm2) is called a large wire. Small (less than or equal to 6 mm2) is called a small wire, and an insulated wire is also called a cloth wire.
Wire and cable include bare wires, electromagnetic wires and insulated wires for electrical appliances, power cables, communication cables and optical cables.

Basically named in the above order, sometimes to highlight important or additional features, features are written before or before the corresponding structure description.
2, the order of the structure description
The product structure is described in terms of the principle from the inside to the outside: Conductor-->insulation-->inner sheath-->outer sheath.
3, simplified
Some structures describe writing or abbreviations without causing confusion.
Composition
From the inside to outside by the inner conductor, insulation, outer conductor and sheath;
Inner conductor: Since the attenuation is mainly caused by the resistance of the inner conductor, the inner conductor has a great influence on the signal transmission
Insulation: Impact attenuation, resistance, return loss and other properties
Outer conductor: loop conductor, shielding effect
Video signal transmission generally adopts direct modulation technology and takes the form of baseband frequency (about 8MHz bandwidth). The most common transmission medium is Coaxial Cable; coaxial cable is specially designed to transmit video signals, and its frequency loss, image distortion, The amplitude of image attenuation is relatively small, which can well complete the task of transmitting video signals.
Commonly used special SYV75 ohm series coaxial cable; commonly used model is SYV75-5 (its non-relay transmission distance for the video signal is generally 300-500m); when the distance is long, SYV75-7, SYV75-9 must be used Axle cable (In actual engineering, the relayless transmission distance of the thick cable can reach 1km or more)
The communication cable is generally used in an imaging device equipped with an electric pan/tilt head and an electric lens, and a remote control decoder must be installed in the field when in use; a communication transmission cable between the on-site decoder and the video matrix switching host of the control center is generally adopted. 2-core shielded communication cable (RVVP) or category 3 twisted pair UTP, with a cross-sectional area per core of 0.3mm² ~0.5mm²; the basic principle for selecting a communication cable is that the longer the distance, the larger the wire diameter; RS-485 communication regulations The basic communication distance is 1200m, but in the actual project, the RVV2-1.5 sheath line can be used to extend the communication length to over 2000m.
The control cable usually refers to the multi-core cable used to control the PTZ and the electric variable lens; one end of the control cable is connected to the PTZ of the controller or the decoder, and the electric lens controls the terminal, and the other end is directly connected to the PTZ. On the corresponding terminals of the electric lens, the control cable provides DC or AC voltage, and the distance is generally short (sometimes less than 1m). There is basically no interference problem, so no Shielded Cable is required.
Commonly used control cables mostly use 6-core or 10-core cables, such as RVV6-0.2, RVV10-0.12; 6-core cables are connected to the top, bottom, left, right, automatic, and public 6 terminals of PTZ respectively, 10 cores In addition to the six terminals of the pan-tilt head, the cable includes four zooming, focusing, aperture, and common terminals of the electric lens; in the monitoring system, the control cable from the decoder to the pan/tilt head and the lens is short due to the short distance. Generally do not make special requirements; and from the central control room controller to the pan and tilt and electric lens distance is as small as tens of meters, as many as several hundred meters, the control cable needs to have certain requirements, that is, the diameter of the wire should be thick, such as selection RVV10-0.5, RVV10-0.75
Audio Monitoring Cable generally uses 4-core shielded communication cable (RVVP) or Category 3 twisted pair UTP, with a cross-sectional area of 0.5 mm² per core;
The audio signal of the monitor head in the monitoring system is transmitted to the central control room and is a point-to-point wiring method. It is transmitted with high voltage and low current, so an unshielded 2-core cable can be used, such as RVV2-0.5.
RVV2*0.3 (signal line) and RVV4*0.3 (2-core + 2-core power) cables are generally used between the front-end detector and the alarm controller; the two controllers are generally used between the alarm controller and the terminal security center. Signal line
Whether the signal line is shielded or twisted or it is a common sheathed cable, it needs to be determined according to the requirements of various brands of products; the rough specification of the signal line diameter is determined according to the distance and quality of the alarm controller and the center; alarm control The power supply of the device generally uses local power instead of centralized power supply in the control room. The line is short, generally adopting RVV 2×0.5" or above specifications; the perimeter alarm and other public area alarm devices generally use centralized power supply mode, and the line is longer. RVV2*1.0" or above specifications are generally used
Cables used in building intercom systems are mostly cables such as RVV, RVVP, SYV, etc.
Has: transmission of voice, data, video images, while cable requirements also reflected in the quality of voice transmission, data transmission rate, video image transmission quality and speed, etc.
Cables that transmit voice signals and alarm signals mainly use RVV4-8*1.0
Video transmission is based on SYV75-5 cable
Some systems must use RVVP cables in the system when they are afraid of external interference or cannot be grounded.
