Testing device for filtering performance test of high humidity dust-containing smoke

Abstract

The invention relates to a testing device for a filtering performance test of high humidity dust-containing smoke and belongs to the field of dust-containing smoke purifying performance tests. The device comprises a smoke generating and filtering system, an ash removing and blowing system and a smoke humidity control system. In the operating process of the testing device, a to-be-tested filter material is installed on a filter material fixing device; air is sequentially heated, humidified and dustiness-increased by using a smoke heater, a spray humidifier and a dust generator to form stable target smoke; testing holes are respectively formed in the inlet and outlet pipelines of the filter device. When the testing device provided by the invention is used for simulating smoke with different temperatures and humidity, change of working conditions can be realized by adjusting corresponding control parameters, the systems are stable, and the operation is simple.

Description

technical field [0001] The invention relates to a test device for testing the filtering performance of high-humidity dusty flue gas, which belongs to the field of testing the purification performance of dusty flue gas. Background technique [0002] When purifying high-humidity dusty flue gas, the water contained in the flue gas is easy to absorb the dust after analysis, forming a gray-water mixture with high viscosity, which is not easy to clean up after capture. At present, this kind of flue gas treatment mainly adopts wet electrostatic precipitator, but wet electrostatic precipitator has weak adaptability to the fluctuation of dust specific resistance, flue gas flow rate and other parameters. With the development of technologies such as filter material manufacturing and post-finishing technology, the filtration technology can gradually adapt to the purification of high-humidity dust-laden flue gas. However, the detection device for the performance of filter material to fil...

[0002] When purifying high-humidity dusty flue gas, the water contained in the flue gas is easy to absorb the dust after analysis, forming a gray-water mixture with high viscosity, which is not easy to clean up after capture

At present, this kind of flue gas treatment mainly adopts wet electrostatic precipitator, but wet electrostatic precipitator has weak adaptability to the fluctuation of parameters such as dust specific resistance and flue gas flow rate.

With the development of technologies such as filter material manufacturing and post-finishing technology, the filtration technology can gradually adapt to the purification of high-humidity dust-laden flue gas. However, the detection device for the performance of filter material to filter high-humidity dust-laden flue gas has not been reported. The present invention provides a The test device used for testing the filtration performance of high-humidity dust-laden flue gas is used to test the performance of filter materials when filtering high-humidity dust-laden flue gas by adjusting parameters such as flue gas temperature, humidity and dust concentration
