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 dedusting equipment Price 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, major Wet dedusting equipment 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.

Wet dedusting equipment Price In the use of wet electrostatic precipitator, we will encounter problems of one kind or another. If we do not know how to solve them, we will not know what to do. What are the reasons for the failure of wet electrostatic precipitator? Next, I will analyze it for you. （1） major Wet dedusting equipment The causes of electrical failure include: electrical components are damaged, corona electrode is not adjusted properly, and porcelain bushing and post insulator through the wall are damaged. ① The electrical components are damaged, such as the fuse is blown, the high-voltage silicon rectifier tube is broken down or the thyristor is damaged, which can lead to the power failure; If the milliammeter is damaged or the transformer fails, the phenomenon of fault type (3) will occur. ② If the nickel chromium alloy wire is not used, the corona electrode will be rusted and broken after being used for a short time. The tension of corona wire is uneven, the force is uneven, and the overload of individual corona electrode will also cause the corona electrode to break; If the corona electrode is not installed in place, deviates from the center of the settling tube, or has too much scale, the electric field will flash over frequently, or even the operation will be interrupted. ③ If the mechanical properties of the through wall porcelain bushing and post insulator are not up to standard and cannot bear the tension of the upper and lower hangers, the insulator will be damaged and cracked. The insulator box temperature control is unreasonable, and the temperature is low or changes violently, which will also cause the insulator to be damaged and cracked; Excessive scale on the surface of insulator will also cause damage and crack of insulator. The final result is that the electric field is grounded, the operation of the electrostatic precipitator is interrupted, and faults (2) and (4) occur.

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 dedusting equipment Price 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 Guiyang major Wet dedusting equipment 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.

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 dedusting equipment Price 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 dedusting equipment 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) Guiyang major Wet dedusting equipment 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.
