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, large 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.

Xianning large Wet electrostatic precipitator WESP has the advantages of high dust removal efficiency, small pressure loss, simple operation, low energy consumption, no moving parts, no secondary dust, low maintenance costs, short production downtime, can work below the flue gas dew point temperature, can be combined with other flue gas treatment equipment due to its compact structure, and diversified design forms. The wet electrostatic precipitator uses liquid to wash the dust collecting electrode surface for dust removal, which can effectively collect fine particles (PM2.5 dust, SO3 acid mist, aerosol), heavy metals (Hg, As, Se, Pb, Cr), organic pollutants (polycyclic aromatic hydrocarbons, dioxins), etc. After the wet electrostatic precipitator is used, the smoke and dust emission in the wet flue gas can reach 10mg/m3 or even below 5mg/m3, and the dust collection performance has nothing to do with the dust characteristics, Wet electrostatic precipitator company It is suitable for the treatment of wet flue gas, especially for the treatment of dusty flue gas after wet desulfurization in power plants and steel plants. However, the equipment investment cost is high, and it needs to be used together with other dedusting equipment. Its investment, technical economy and operating cost should be evaluated from an overall perspective.

（1） Wet electrostatic precipitator company The operating environment should always be kept clean, the fan surface should be kept clean, and the air inlet and outlet should be free of sundries. Regularly remove dust and other sundries in the fan and pipe. （2） large Wet electrostatic precipitator It can only be operated when the fan is completely normal. At the same time, it is necessary to maintain sufficient capacity of power supply facilities and stable voltage. Open phase operation is strictly prohibited. The power supply lines must be dedicated lines, and temporary lines should not be used for long-term power supply. (3) In case of abnormal sound, serious heating of motor, electrification of shell, tripping of switch, failure to start and other phenomena of fan during operation, the fan shall be stopped immediately for inspection. To ensure safety, maintenance is not allowed during the operation of the fan. After the maintenance, the test run shall be carried out for about five minutes, and the machine shall be restarted after confirming that there is no abnormal phenomenon. （4） Xianning Wet electrostatic precipitator company Replenish or replace lubricating grease for bearings irregularly according to the service environmental conditions (it is not necessary to replace lubricating grease for motor enclosed bearings within the service life). To ensure good lubrication of the fan during operation, the number of times of oiling shall not be less than 1000 hours/time. For enclosed bearings and motor bearings, fill 2/3 of the inner and outer rings of bearings with ZL-3 lithium based lubricating grease. It is strictly prohibited to run without oil. (5) The fan shall be stored in a dry environment to prevent the motor from moisture. Rain proof measures shall be taken when the fan is stored in the open air. The fan shall be prevented from collision during storage and handling to avoid damage to the fan.

The key points of factors to be considered in the technical approach to the transformation of wet electrostatic precipitators: the wet electrostatic precipitators built before the mid-1970s could not meet the requirements of the new emission standards because of the low requirements for boiler smoke and dust emissions, the small selection of equipment capacity, the outdated structure of electrostatic precipitators, aging of dust removal equipment, low dust removal efficiency and other reasons, These electrostatic precipitators have a problem of transformation to further improve efficiency. large Wet electrostatic precipitator company The improvement measures for the original equipment should be considered from both technical and economic aspects, and the following technical approaches are generally adopted: 1. Discover the potential of electrostatic precipitator equipment. For example, adjust the rapping cycle and rapping force of the electrode to improve the corona power and reduce the re flying of dust; Improve the uneven distribution of flue gas velocity and readjust the technical parameters of the airflow distribution device; Adjust the control mode or power supply mode of the power supply equipment. 2、 large Wet electrostatic precipitator Combination with other dedusting equipment. That is, a primary precipitator is added before or after the electrostatic precipitator. 3. Increase the capacity (or dust collection area) of the electrostatic precipitator. That is, add an electric field, or increase or widen the electric field of the electrostatic precipitator.

Fans can be classified into several types according to the materials used, such as iron shell fans (ordinary fans), glass fiber reinforced plastic fans, plastic fans, aluminum fans, stainless steel fans, etc. Wet electrostatic precipitator company In the direction of gas flow. Fans can be classified into centrifugal, axial, diagonal (mixed flow) and cross flow fans according to the direction of gas flow. (1) Centrifugal fan. The airflow enters the impeller of the fan axially and flows mainly along the radial direction. This type of fan is made according to the principle of centrifugal action, and its products include centrifugal fan, centrifugal blower and centrifugal compressor. (2) Axial flow fan. The airflow enters the impeller of the fan axially and flows approximately along the axis on the cylindrical surface. Such fans include axial fans, axial blowers and axial compressors. (3) Rotary fan. Xianning large Wet electrostatic precipitator Use the rotor rotation to change the air chamber volume to work. Common varieties include Roots blower and rotary compressor.

Xianning Wet electrostatic precipitator company The development trend and direction of wind turbine in the future are analyzed as follows: wind turbine is mainly used for ventilation and air exchange in various fields of national economy and various places, such as metallurgy, petrochemical, electric power, urban rail transit, textile, shipbuilding, etc. In addition to the traditional application fields, there will still be great development prospects in more than 20 potential market fields, such as comprehensive utilization of coal gangue, new dry process clinker technology, energy saving in metallurgical industry and comprehensive utilization of resources. large Wet electrostatic precipitator With the increasing competition in the wind turbine manufacturing industry, mergers and acquisitions and capital operations among large wind turbine manufacturing enterprises are becoming increasingly frequent. Domestic outstanding wind turbine manufacturing enterprises are increasingly paying attention to the research of the industry market, especially the in-depth research of the industry development environment and product buyers.
