Quality appraisal of wet electrostatic precipitator system

wet electrostatic precipitator is a new type of dust removal equipment used to deal with trace amounts of dust and fine particles. It is mainly used to remove dust, acid mist, aerosols, PM2.5 and other harmful substances in moist gases. It is an ideal equipment for controlling fine particles and dust pollution in exhaust gas.

Wet type electrostatic precipitators and dry type electrostatic precipitators, that is, the dust removal working principles of electrostatic precipitators are basically the same. They all go through three stages of charging, dust collection and dust cleaning. Charging means first charging the dust through high-voltage discharge. The charged dust reaches the dust collecting pipe or dust collecting plate under the action of the positive and negative electric field force, and then the dust is cleaned.

Zhongke Testing and Appraisal Institute can provide wet electrostatic precipitator system quality appraisal services and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

There are many types of wet dust collectors. According to their structures, they generally include the following types:
(1) Gravity spray wet dust collector, such as spray strip tower.
(2) Cyclone wet dust collector, such as: cyclone water film dust collector, water film dust collector.
0 (3) Self-excited wet dust collector, such as: impulse dust collector, water bath dust collector. 123 (4) Packing wet dust collector, such as: packed tower, turbulent ball tower. 456 (5) Foam wet dust collector, such as: foam dust collector, cyclone dust collector leaky plate tower. 789(6) Venturi wet dust collector, such as: Venturi dust collector. 012(7) Mechanically induced dust collector, such as: water wheel dust collector. 34

According to the information provided by the client, the supplier and the buyer signed a contract to customize a wet electrostatic precipitator system including a fiberglass flue. During the installation process of the supplier, the buyer found that the thickness of the middle part of the fiberglass flue did not meet the technical agreement requirements. In order to ascertain the facts, the purchaser proposed to evaluate the thickness of the "glass fiber reinforced plastic flue of the wet electrostatic precipitator system" involved in the case, and to evaluate whether its structural strength meets the safety requirements stipulated in the standard.

identification analysis results:

The identification expert group discussed and comprehensively analyzed the relevant information, on-site investigation and inspection conditions and calculation results of the "wet electrostatic precipitator system fiberglass flue" involved in the case, and made the following identification opinions:

1, the "wet electrostatic precipitator system involved" The total thickness of the "glass fiber reinforced plastic flue" does not meet the requirements of ≥30mm agreed between the supplier and the buyer, and the thickness of the intermediate structural layer does not meet the requirement of ≥27mm agreed by the supplier and the buyer;

2. When using the relevant design parameters in the "Production and Installation Agreement", "Flue Layout Plan" and "Technical Agreement" as the calculation basis, the structural strength of the "Wet Electric Precipitation System FRP Flue" involved in the case meets the standard GB/T Safety requirements specified in 30812-2014 "Glass fiber reinforced plastic flues for coal-fired power plants".
