The wet electrostatic precipitator is mainly used to purify water vapor, odor, acid mist and other harmful substances in the exhaust gas discharged by the factory. As an air pollution control equipment, it has also been widely used. let's Wet electrostatic precipitator manufactor Understand its system composition together. 1. Composition of wet electrostatic precipitator system. According to its working principle, the control system of wet electrostatic precipitator generally includes high pressure system, water treatment system, low pressure heating and hot air purging system, upper computer system, etc. 2. Design of wet electrostatic precipitator system. (1) major Wet electrostatic precipitator High voltage system and wet electrostatic precipitator charge the dust through corona discharge of high voltage system. The charged dust reaches the dust collecting plate under the effect of electric field force, and then the dust is removed by regular scouring. (2) Guigang major Wet electrostatic precipitator Water treatment system. This system deals with the problem of secondary water pollution. It is mainly the water discharged after equipment spraying and flushing, which contains a lot of acid substances and fine particles. Direct discharge will cause secondary pollution. The recycling of water in the equipment consists of two steps: neutralization and acid removal, and separation of suspended solids, so that the sewage can be turned into industrial water suitable for spraying. (3) Heating system. The heating system includes insulator incubator heating, hot air purging heating, and the hot air purging system is composed of fan, butterfly valve and heater. When it starts actively, it starts in the order of fan, butterfly valve and heater. When actively closing, it shall be closed in reverse order. (4) Upper computer system. The selected upper computer system is an industrial control computer, and the network front-end computer is used to enable the system to have extraordinary data acquisition and processing capabilities, so as to meet the requirements of wet electrostatic precipitator for centralized management, decentralized control, energy conservation and emission reduction.

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 manufactor 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. Guigang major Wet electrostatic precipitator Use the rotor rotation to change the air chamber volume to work. Common varieties include Roots blower and rotary compressor.

major Wet electrostatic precipitator Common fault: the working medium of the fan in the cement industry often contains a certain amount of homogeneous particles with different sizes and shapes, such as the induced draft fan of the dust removal system and the blower for pneumatic conveying. Because these fans work in the dusty air flow, the dust particles in the air flow will not only wear the fan, but also attach ash on the fan blades, and the wear and ash deposition are uneven. As a result, the balance of the fan rotor is destroyed, which causes the fan vibration and shortens the life of the fan. In serious cases, the fan can not work normally. Especially, the fan blades are worn most seriously, Wet electrostatic precipitator manufactor It not only destroys the flow characteristics in the fan, but also easily leads to major accidents such as blade fracture and runaway. The wear of transmission parts is also a common problem of fans, including various shafts, rollers, reducers, motors, pumps and other bearing positions, bearing seats, keyways, threads and other parts. The traditional repair welding machine processing method is easy to cause material damage, resulting in deformation or fracture of parts, with greater limitations; Brush plating and spray re machining methods often require outsourcing, which not only requires long repair cycle and high cost, but also can not fundamentally solve the causes of wear (poor impact resistance and yield of metal) because the repair materials are metal materials; Many parts can only be scrapped and replaced, which greatly increases the production cost and inventory of spare parts, leaving the enterprise's good resource advantage idle and wasted

Dust leakage may occur when the wet electrostatic precipitator is used at ordinary times, so that the precipitator can not achieve the expected use effect when it is used Wet electrostatic precipitator manufactor Let's specifically analyze the causes of dust leakage. 1. The dust remover is mainly assembled from the clean air chamber and the hopper. In this part, screws are used at the connection position between the upper box and the hopper. If the sealing strip used in this place is unqualified, dust will leak out. In addition to affecting the normal use of the equipment, the poor performance of the dust remover in use will have a great impact on the environment of the whole workshop and the surrounding environment. Even some wet electrostatic precipitators have a lot of materials with recycling value in the recycled dust. two Guigang major Wet electrostatic precipitator Improper filtering wind speed used in dedusting may also lead to dust leakage, because the dust will be adsorbed on the filter bag when the temperature is too high, so the resistance of dedusting equipment will increase when it is used, leading to leakage. 3. The dedusting bag is also a device that plays a major role in the operation and use of the equipment. If the density of the bag itself is relatively small, it may cause dust leakage to each other. Therefore, when selecting the bag, it is also necessary to select the one with better quality for use, and it is also necessary to do a good job of maintenance when using it again.
