Forecast from domestic market capacity. Qinzhou Wet electrostatic precipitator company Fans vary greatly according to different pressure and flow requirements. Therefore, the fan demand should be differentiated according to its type and size, and predicted according to the demand of different industries. According to incomplete statistics, the annual average growth rate of national fan output was 13.8% from 1980 to 1996. customized Wet electrostatic precipitator It is estimated that the total output of wind turbines in China will be 2.6 million to 2.9 million in 2005 and 3.1 million to 3.25 million in 2010. According to the statistics of fan industry over the years, it is predicted that the output of centrifugal compressors will be 1.6 million to 1.8 million in 2005 and 2 million to 2.1 million in 2010; The output of axial compressor is 260000 in 2005, and is expected to reach 360000 in 2010; The market share of turbine compressor and blower will reach about 70% in 2005

Among all kinds of mechanical and electrical equipment in all walks of life in China, the motors matched with fans account for about 60% of the installed capacity of national motors, and the power consumption accounts for about one-third of the total power generation in China. In particular, Wet electrostatic precipitator company Most fans have the phenomenon of pulling a cart from a horse during use. In addition, due to changes in production and technology, it is necessary to frequently adjust the gas flow, pressure, temperature, etc; Many units still adopt the backward way of adjusting the opening degree of the wind shield or valve to adjust the gas flow, pressure, temperature, etc. In fact, this is to meet the requirements of process and working conditions for gas flow regulation by artificially increasing resistance at the cost of wasting electric energy and money. This backward regulation mode not only wastes valuable energy, but also has poor regulation accuracy, which is difficult to meet the requirements of modern industrial production and services, and has serious negative effects. With the continuous improvement and development of frequency conversion technology in recent ten years. The performance of variable frequency speed regulation is becoming increasingly perfect, customized Wet electrostatic precipitator It has been widely used in AC speed regulation in different fields. It has brought considerable economic benefits to enterprises and promoted the automation process of industrial production.

The use of wet electrostatic precipitators is becoming more and more common. How much do you know about the equipment? Today, I'm going to popularize knowledge for you and talk about the advantages and disadvantages of wet electrostatic precipitator. Let's learn together. Advantages of electrostatic precipitator High purification efficiency, capable of spreading fine particles of more than 0.01 microns. In the design, different operating parameters can be used to meet the required purification efficiency. ⑵ The resistance loss is small, generally below 20 mm water column. Compared with cyclone dust collector, the total power consumption is small even considering the power consumption of power supply unit and rapping mechanism. ⑶ Qinzhou Wet electrostatic precipitator The allowable operating temperature is high. For example, the allowable operating temperature of SHWB type circuit dust collector is 250 ℃. Other types can reach 350~400 ℃ or higher. ⑷ Large gas processing range. ⑸ customized Wet electrostatic precipitator Automatic operation control can be fully realized. Disadvantages of electrostatic precipitator The equipment is relatively complex, requiring a high level of equipment allocation, installation and maintenance management. ⑵ There are certain requirements for the specific resistance of dust, so there is a certain selectivity for dust, which can not make all dust obtain high purification efficiency. ⑶ It is greatly affected by the operating conditions such as air temperature and temperature. If the same kind of dust is operated at different temperatures and humidities, the results will be different. Some dust can work well at a certain temperature and humidities, but the ESP can hardly be used at another temperature and humidities due to the change of dust resistance. ⑷ Wet electrostatic precipitator company The primary investment is large, and the horizontal electrostatic precipitator covers a large area. ⑸ At present, the practical effect in some enterprises can not meet the design requirements.

Wet electrostatic precipitator company The work starts before the fan is used. one Qinzhou Wet electrostatic precipitator company Carefully read the fan operation instructions and product samples, and be familiar with and understand the fan specifications, forms, impeller rotation direction and air flow in and out direction; Check whether all parts of the fan are in good condition again, or they can be installed and used only after being repaired. 2. The fan must be installed with safety devices to prevent accidents, and installed and wired by professionals familiar with relevant safety requirements. 3. The air duct connecting the inlet and outlet of the fan has separate support, and it is not allowed to add the overlapping weight of the duct to the components of the fan; When installing the fan, pay attention to the horizontal position of the fan, and adjust the connection between the joint surface of the fan and the foundation and the air outlet pipe to make it coincide naturally. Forced connection is not allowed. four customized Wet electrostatic precipitator After the fan is installed, move the impeller by hand or lever to check whether it is too tight or rubbed, and whether there is any object that hinders the rotation. The test run can be carried out only when there is no abnormal phenomenon. The exposed part of the fan transmission device should be equipped with a protective cover (provided by the user). If the fan inlet is not connected, a protective screen or other installation device (provided by the user) should also be added. 5. The power distribution control box of the fan must match the corresponding fan (power, voltage, pneumatic mode, control mode, etc.). 6. The fan wiring should be made by a professional electrician, and the wiring must be correct and reliable. Especially, the wiring number at the electric control box should be consistent with the number on the fan terminal. The fan shell should be reliably grounded. The grounding must be reliable, and zero connection cannot be used instead of grounding. 7. After all fans are installed, check whether there are any left tool box sundries inside the fan

customized Wet electrostatic precipitator The wet electrostatic precipitator mainly has two structural forms. One is to use corrosion-resistant conductive materials (which can be non-metallic materials with excellent conductivity or metal materials with corrosion-resistant characteristics) as the dust collector, and the other is to use non-conductive non-metallic materials as the dust collector by forming a conductive water film through water spray or overflow. Wet electrostatic precipitators can also be divided into cross flow type (horizontal) and vertical flow type (vertical) according to the flow direction of waste gas. The cross flow type is mostly plate structure, Qinzhou Wet electrostatic precipitator The gas flows in and out in the horizontal direction, and the structure is similar to the dry electrostatic precipitator; The vertical flow type is mostly tubular structure, and the gas flow direction is vertical. Generally speaking, the efficiency of vertical flow wet electrostatic precipitator is twice as high as that of cross flow wet electrostatic precipitator under the condition of the same ventilation cross-sectional area. The dust deposited on the electrode plate can be washed down by water. Wet dust removal can avoid the re flying of captured dust and achieve high dust removal efficiency. Since there is no rapping device, the operation is also more reliable. The device that forms conductive film on the surface of the dust collector by means of water spray or overflow water has problems of corrosion, sludge and sewage treatment. It is only used when the dust concentration of the gas is low and the dust removal efficiency is required to be high; The wet electrostatic precipitator using corrosion-resistant conductive materials as dust collector does not need long-term water spraying or overflow water, Wet electrostatic precipitator company Regular flushing is only carried out according to the operating conditions of the system, and only a small amount of water is consumed. This part of water can be recycled, and the dust collection system is basically free of secondary pollution.
