Electrostatic-bag composite dedusting test device and method

Abstract

The invention discloses an electrostatic-bag composite dedusting test device. The electrostatic-bag composite dedusting test device comprises a device body, a combustion system, a flue gas and air system, a detection system and a detection part, wherein the device body comprises a shell, an electrostatic dedusting device and a bag dedusting device; the combustion system comprises a pulverized coal bunker and a boiler which are mutually connected; the flue gas and air system comprises an air feeder, a draught fan and an air bypass flue; the detection system comprises a first measurement hole in an inlet flue, a second measurement hole in the inlet of the bag dedusting device, and a third measurement hole in an outlet flue; and the detection part is used for detecting the concentration of dust of each measurement hole. A first smoke concentration before smoke dedusting, a second smoke concentration after using the electrostatic dedusting device, and a third smoke concentration after using the bag dedusting device are respectively detected through the first measurement hole, the second measurement hole and the third measurement hole in the dedusting process, so that the dedusting efficiencies of the electrostatic dedusting device and the bag dedusting device are acquired. The invention further provides an electrostatic-bag composite dedusting test method on the basis of the test device.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to an electric bag composite dust removal test device and a test method. Background technique [0002] In recent years, smog has frequently broken out in many places in my country, and regional pollution has become increasingly obvious. Under the severe environmental protection situation, the state has issued a number of environmental protection policies, and the environmental protection requirements have become more stringent. However, my country's primary energy endowment of "more coal, less oil and less gas" determines that the energy supply pattern of coal-fired power generation will exist for a long time, and the thermal power industry is facing huge pressure to reduce emissions. At the end of 2015, the state issued a work plan for the full implementation of ultra-low emissions from coal-fired power plants, among which the smoke and dust emissions are required to be less ...

AI Technical Summary

Problems solved by technology

[0007] First, it is separated from the core mechanism research of electric bag composite dust removal, for example, it is impossible to measure the classification dust removal efficiency in the process of electric bag composite dust removal, and it is impossible to conduct research on the optimal coupling ratio between the electric area and the bag area, etc.

[0008] Second, only macroscopic experimental research can be carried out, and it is impossible to conduct internal or microscopic experiments

[0009] Third, the existing test device can only conduct cold test, but not hot test. In fact, the device with hot test conditions can better study the mechanism of electric bag composite dust removal
