Hunan Wet electrostatic precipitator Classified by layers. There are many classification methods for fans, which can be roughly classified according to the following levels: (1) According to the level of pressure generated, they can be divided into: volumetric: reciprocating and rotary; Turbine type: centrifugal, axial flow, mixed flow and cross flow, jet type. Fan generally refers to turbine type, namely centrifugal, axial, mixed flow, cross flow and other forms. Its main characteristics are: centrifugal fan: higher pressure, but smaller air volume. Axial flow fan: higher air volume, but lower pressure. Mixed flow fan: the air volume and pressure are between centrifugal fan and axial fan. Horizontal fan: with high dynamic pressure, it can obtain flat airflow. (2) large Wet electrostatic precipitator According to the different materials used, it can be divided into:; Iron shell fan (ordinary fan), glass fiber reinforced plastic fan, plastic fan, aluminum fan, stainless steel fan, etc. (3) According to the direction of gas flow, it can be divided into centrifugal type, axial flow type, diagonal flow type (mixed flow type) and cross flow type. (4) According to the flow direction of the airflow entering the impeller, it can be divided into axial flow fan, centrifugal fan and diagonal flow (mixed flow) fan. (5) Wet electrostatic precipitator Price It can be divided into: press in local fans and flame-proof motors placed outside or inside the flow channel, and flame-proof motors placed inside the explosion-proof sealing chamber of the extraction type local fans. (6) According to the form of pressurization, it can also be divided into single-stage, two-stage or multi-stage pressurization fans

Wet dust remover is a device that uses the action of water or other liquids and dusty gases to remove dust particles. When dust particles meet with sprayed water droplets, water films or wetted walls and devices The process of wetting, condensation, diffusion and sedimentation takes place, so it is separated from the gas to purify the gas. Hunan Wet electrostatic precipitator Price It is characterized by purifying dust at the same time It can also purify gas, large Wet electrostatic precipitator When the flue gas contains combustible components, the use of wet dust collectors can avoid equipment explosion, and the dust removal effect can generally meet the environmental protection requirements. The equipment is small and the investment is relatively low. Therefore, there are three wet dust collectors used in dust removal projects in mining, metallurgy, machinery, light industry, building materials and other industries. Sludge containing sewage must be treated, otherwise secondary pollution may occur, Therefore, it is not widely used as dry dust collector. There are many types of wet dust collectors. According to their structures, there are the following types: ① gravity spray wet dust collectors - spray scrubbing towers; ② Cyclone wet dust collector - cyclone water film dust collector, water film dust collector; ③ Self excited wet dust collector - impulse dust collector, water bath dust collector; ④ Packed wet dust collector - packed tower, turbulent ball tower; ⑤ Foam wet dust collector - foam dust collector Cyclone dust collector, leaky plate tower; ⑥ Venturi wet dust collector - Venturi tube dust collector; ⑦ Mechanical induction wet dust collector - water wheel dust collector.

In order to avoid man-made faults and accidents caused by improper maintenance, prevent the occurrence of natural faults and accidents of fans and motors in all aspects, so as to give full play to the efficiency of equipment and extend the service life of equipment, therefore, the maintenance of fans must be strengthened. （1） Working system of fan maintenance The fan maintenance personnel must pay attention to the following points: 1. The fan can only be operated when the fan equipment is completely normal. 2. If the fan equipment starts after maintenance, pay attention to whether all parts of the fan are normal. 3. Regularly clean the dust, dirt, water and other impurities inside the fan and gas transmission pipeline, and check whether the impeller is worn and rusted, if any, repair and replace it in time. 4. Regularly replace the lubricating oil (recommended 3-6 months). It is recommended to add N46 (ISO VG46, 30) in summer and N32 (ISO VG32, 20) in winter. The oil level should be at 1/2 of the oil window. 5. Regularly check (3-6 months is recommended) couplings, pulleys, etc. If parts are found to be worn or rusted, they should be repaired and replaced immediately. 6. The equipment shall not be repaired during operation.

Preparations for fan installation. large Wet electrostatic precipitator Before unpacking the fan, check whether the package is intact, whether the nameplate parameters of the fan meet the requirements, and whether all accompanying accessories are complete. Carefully check whether the fan is deformed or damaged during transportation, whether the fasteners are loose or fall off, and whether the impeller is scratched, and check all parts of the fan. Hunan Wet electrostatic precipitator Price If any abnormality is found, it shall be repaired before use. Use a 500V megger to measure the insulation resistance between the fan housing and the motor winding. The value should be greater than 0.5 megohm. Otherwise, the motor winding should be dried. The temperature during drying should not exceed 120 ℃. Prepare various materials, tools and sites required for fan installation.
