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. In order 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. Yichang major Centrifugal fan 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 Centrifugal fan company 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.

major Centrifugal fan 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, Yichang Centrifugal fan 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, Centrifugal fan 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.

How are dust collectors classified, major Centrifugal fan Do you know how to distinguish it and how to define its economic type? Let's talk about it from these aspects. 1. Dust removal efficiency. Yichang Centrifugal fan Dust removal efficiency refers to the ratio of the amount of dust collected by the dust collector to the amount of dust entering the dust collector. According to the total dedusting efficiency, the dedusters can be divided into: low efficiency dedusters (50~80%), medium efficiency dedusters (80~95%) and high efficiency dedusters (more than 95%). 2. Dust removal resistance. The resistance indicates the pressure loss when the airflow passes through the dust remover. According to the resistance, dust collectors can be divided into low resistance dust collectors (Δ P<500Pa), medium resistance dust collectors (Δ P=500 ～ 2000Pa) and high resistance dust collectors (Δ P=2000 ～ 20000Pa). 3. Economy. Economy is one of the important indexes for evaluating dust remover, which includes equipment cost and operation and maintenance cost of dust remover. Among all kinds of dust collectors, the equipment cost of electrostatic precipitator is the highest, followed by bag type dust collector, Venturi tube dust collector, cyclone dust collector is the lowest electrostatic precipitator: the dust removal efficiency is high, generally above 99%, and the design efficiency is up to 99.99%. The wet dust collector is commonly known as "water dust collector" : The filtration efficiency can reach more than 85%, and the integrated desulfurization and dust remover of stone water film+swirl plate>>about 80% of desulfurization and dust removal can reach as high as about 95%.

Users mainly pursue high efficiency, low noise, long life, and low price. The other is capital and technology intensive. The product structure is complex, the manufacturing cycle is long, and the completeness and systematicness are also strong. Moreover, it operates under high pressure, high temperature and high speed conditions, and some even operate under severe conditions. Users have different requirements for this type of fan. For turbine blowers, compressors and large ventilators, users mainly pursue high quality, high reliability, smooth operation and long cycle

Fan is the abbreviation of Chinese custom for gas compression and gas transmission machinery. Generally speaking, fans include fans, blowers, and wind turbines. Yichang Centrifugal fan company 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
