Device and method for detecting dust removal performance of cloth bag in coal-fired power plant

Abstract

The invention discloses a device and method for detecting the dust removal performance of a cloth bag in a coal-fired power plant. The device comprises a temperature control system, a detection deviceand an intelligent control feedback system. Firstly, the first air pump and the second air pump which are provided with the frequency converters are arranged, stable pumping force can be provided, and output can be adjusted in real time. And secondly, a temperature control system is arranged, so that the flue gas temperature in the cloth bag dust collector device of the power plant can be simulated, and the detected result is closer to the actual result. And then a dust generating device, a static electricity removing premixing device and an optical concentration detection device are arranged, so that the accuracy of the dust concentration in the gas can be ensured. And finally, the compression air cylinder provides back-blowing rapping power for the device, so that the device can test the static dust removal efficiency and the dynamic dust removal efficiency. According to the invention, the detection working condition is optimized, the temperature field condition is provided, the detection result is more rigorous and accurate, the smoke concentration detection accuracy is improved, and the parameters of the dust removal efficiency measured by the device are more diversified.

Description

technical field [0001] The invention relates to a device and method for detecting the dust removal performance of a bag in a coal-fired power plant. Background technique [0002] At present, the domestic environmental protection situation is severe, and the flue gas environmental protection standards have been proposed for large coal-fired power plants and chemical energy industries. Bag dust removal is one of several common methods for flue gas dust removal. The heavy smoke flows through the bag, and the windward side of the bag can block a large amount of dust, and the clean and dust-removed flue gas can flow out through the bag. However, for the performance of the new bag dust removal and whether the efficiency of the bag dust removal in operation can reach the standard, a clear equipment and method are required to carry out related testing, which is conducive to controlling the quality of the new dust bag, and can check whether the bag is in operation. It needs to be re...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem of inaccurate measurement of bag dust removal efficiency existing in the prior art, and the flue gas containing dust in actual working conditions is carried out at a certain temperature during the bag dust removal process, while the existing detection The equipment does not take this situation into consideration, so it provides a device and method for testing the performance of bag dust removal in coal-fired power plants
