major Wet electrostatic precipitator The fan is a kind of driven fluid machinery, which relies on the input mechanical energy to increase the gas pressure and discharge gas. Fan is the abbreviation of Chinese custom for gas compression and gas transmission machinery. Generally speaking, fans include fans, blowers, and wind turbines. Huanggang Wet electrostatic precipitator manufactor Fans are widely used for ventilation, dust discharge and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, as well as ventilation and induced draft of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household appliances; Drying and delivery of grain, wind source of wind tunnel and inflation and propulsion of hovercraft
major 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, Huanggang 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 manufactor 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.
(1) Wet electrostatic precipitator manufactor 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) major 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) Huanggang Wet electrostatic precipitator manufactor 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 wet electrostatic precipitator is a new kind of dust removal equipment used to treat micro dust and micro particles, major Wet electrostatic precipitator It is mainly used to remove dust, acid mist, water droplets, aerosols, odor, PM2.5 and other harmful substances in humid gases, and is an ideal equipment for controlling atmospheric dust pollution. The wet electrostatic precipitator is usually referred to as WESP, which has the same basic principle as the dry electrostatic precipitator. It goes through three stages: charging, collection and dust removal. The principle of wet electrostatic precipitator is the same as that of dry electrostatic precipitator, Huanggang Wet electrostatic precipitator The dust is charged by high-voltage corona discharge, and the charged dust reaches the dust collecting plate/tube under the action of electric field force. The dry electrostatic precipitator mainly deals with dry gas with very low water content, while the wet electrostatic precipitator mainly deals with wet gas with high water content or even saturation. There is a big difference between WESP and DESP in the way of removing the dust collected on the dust collecting plate/pipe. The dry electrostatic precipitator generally uses mechanical rapping or acoustic cleaning to remove the dust on the electrode, while the wet electrostatic precipitator uses regular flushing to remove the dust along with the flow of flushing fluid
While meeting the new standard, the wet electrostatic precipitator can also control the haze fine particles, sulfur trioxide aerosol droplets, organic pollutants, heavy metal pollutants, etc., which has great social benefits. The air pollutant control mode of SCR+ESP/FF+WFGD+WESP is also a relatively effective way to control pollutants in Shangshan Coal fired Power Plant. Wet electrostatic precipitator manufactor Common dust control technologies, among which the dry electrostatic precipitator, the electrostatic fabric composite precipitator and the bag type precipitator are used as the front section dust control technology, cannot guarantee the ultra clean emission of flue gas dust after the desulfurization device, while the wet electrostatic precipitator arranged at the downstream of the wet desulfurization device will be used as a reliable terminal dust control technology. The working principle of wet electrostatic precipitator is similar to that of dry electrostatic precipitator. It is high-voltage corona discharge that charges dust or water mist, and charged particles reach the dust collecting plate under the action of electric field force, major Wet electrostatic precipitator However, in terms of the way of dust, the dry electrostatic precipitator uses mechanical vibration, while the wet electrostatic precipitator uses flushing fluid to flush electricity, washing the dust captured on the dust collection plate into the ash hopper and then discharging the wet electrostatic precipitator. The advantages of the wet electrostatic precipitator are: because the mass and heat transfer processes occur simultaneously in the process of gas and liquid contact, this type of precipitator has the function of dust removal, It also has the function of flue gas cooling and absorption of harmful gases. Suitable for high temperature. High temperature, flammable, explosive and harmful gases; Normal operation and high purification efficiency; Dust and gas that can be used for gathering fog and dust; Exhaust volume balance; Simple structure. Low investment, convenient operation and maintenance.
The operating principle of wet electrostatic precipitator is different from other equipment. The dusty gas enters the expanded ash hopper of the wet electrostatic precipitator for pre collection, and is evenly distributed between each filter bag through the guide plate. The dust is retained on the surface of the filter bag. To make the equipment resistance not exceed 1200pa, the high-pressure gas will pulse through the electromagnetic pulse valve, so that the compressed air in the air bag will be ejected from the nozzle hole (called primary air) The surrounding air (called secondary air), which is several times of the primary air, is induced through the venturi to enter the filter bag to make the filter bag expand rapidly in an instant, and shake off the dust with the reverse effect of the air flow to reach the purpose of ash removal. The microcomputer automatic control device is used to adjust the ash cleaning cycle and pulse spraying time randomly according to the dust concentration, so that the dust collector can operate within the resistance range. When changing the bag of the wet electrostatic precipitator, open the top bag changing cover and directly pull out the filter bag, which is simple and convenient to protect. Huanggang major Wet electrostatic precipitator Wet electrostatic precipitators are mostly used in bag type precipitators. Dust removal bags are installed in the gas box. Wet electrostatic precipitators are mostly external filter type. Dust is collected in the ash hopper of wet electrostatic precipitators through the injection of pulse solenoid valves. The wet electrostatic precipitator is installed in a simple structure. This device is planned as an internal filtering structure, which can change the external pressure of the wet electrostatic precipitator to the internal pressure. In this way, the shell of the wet electrostatic precipitator can be structured without external iron plate sealing, which saves costs and does not hinder the use of the wet electrostatic precipitator. The processing of wet electrostatic precipitator is particularly important. In recent years, some Wet electrostatic precipitator manufactor Small manufacturers use small sewing machines as processing equipment, and use low-quality thread as raw materials during processing, which is fake, and the processing level is far behind. The wet electrostatic precipitator will open lines, cracks, and drop the bottom after a short time of operation. Although the size of the cloth bag is slightly smaller, it can also be used, but after absorbing the dust with large specific gravity, the bag will drop after a period of use.
