Sichuan large Wet electrostatic precipitator WESP has the advantages of high dust removal efficiency, small pressure loss, simple operation, low energy consumption, no moving parts, no secondary dust, low maintenance costs, short production downtime, can work below the flue gas dew point temperature, can be combined with other flue gas treatment equipment due to its compact structure, and diversified design forms. The wet electrostatic precipitator uses liquid to wash the dust collecting electrode surface for dust removal, which can effectively collect fine particles (PM2.5 dust, SO3 acid mist, aerosol), heavy metals (Hg, As, Se, Pb, Cr), organic pollutants (polycyclic aromatic hydrocarbons, dioxins), etc. After the wet electrostatic precipitator is used, the smoke and dust emission in the wet flue gas can reach 10mg/m3 or even below 5mg/m3, and the dust collection performance has nothing to do with the dust characteristics, Wet electrostatic precipitator Price It is suitable for the treatment of wet flue gas, especially for the treatment of dusty flue gas after wet desulfurization in power plants and steel plants. However, the equipment investment cost is high, and it needs to be used together with other dedusting equipment. Its investment, technical economy and operating cost should be evaluated from an overall perspective.

Wet electrostatic precipitator Price Different types of dust remover equipment have their own precautions. When we usually use the dust remover equipment, we should tell my customer friends some application matters. What matters should we consider when using wet electrostatic precipitator? Matters needing attention on the application of wet electrostatic precipitator. 1. The wet electrostatic precipitator shall be put into the insulator chamber electric heating and hot air purging system at least 8 hours in advance to ensure that the temperature of the insulator chamber is more than 60 ℃. 2. The wet desulfurization system of the wet electrostatic precipitator is put into operation early to prevent dry and high-temperature smoke from entering the wet electrostatic precipitator, which will lead to scaling of internal parts and damage of internal anti-corrosion coating. three large Wet electrostatic precipitator The wet dust collector can be opened when the following three conditions are met together: 3.1 The wet electrostatic precipitator is operated with 25% of the oil gun remaining and 35% of the powder feeding is normal and stable or the oil gun is completely withdrawn. 3.2 The temperature of flue gas entering the wet electrostatic precipitator is lower than 70 ℃. 3.3 Desulfurization equipment has been opened. 4. The process of opening the wet electrostatic precipitator: first open the low-pressure water supply system and then the high-pressure power supply system.

Wet electrostatic precipitator 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） large Wet electrostatic precipitator 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.

The wet electrostatic precipitator is a new kind of dust removal equipment used to treat micro dust and micro particles, large 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, Sichuan 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

The selection of fans Product performance and fan performance listed in the selection table are based on the performance of delivering air under standard conditions. Therefore, when the use condition is non-standard, the H4-72-12 centrifugal fan must convert the use performance into the performance under standard conditions according to the relationship in the table above, and then select according to the performance and selection table. （3） Treatment of excessive or insufficient flow During use, excessive or insufficient flow often occurs. There are many reasons for this phenomenon. If the flow is high and low during use, it is mainly because the resistance in the pipe network is high and low, or the fan works in a non working area. If it is gradually reduced after a long time during use, it is mainly due to pipe network blockage. After the fan is newly installed, the flow is too large or insufficient during the formal operation. The main reasons for this phenomenon are as follows: 1. The actual value of pipe network resistance is too different from the calculated value. In the general pipe network characteristic equation, H=KQ2, if the actual value K of K-resistance coefficient is less than the calculated value K, the flow will increase; If the actual value K is greater than the calculated value K, the flow decreases. See (b) below.
