Abstract

The invention relates to a multifunctional corrosivity test platform for filtering materials, and belongs to the field of performance detection devices for filtering materials. The test platform comprises a sample holding device, a smoke supplying device, an original-smoke channel and a smoke purification channel, wherein the smoke supplying device, the original-smoke channel and the smoke purification channel are communicated in sequence. The sample holding device is disposed at the joint of the original-smoke channel and the smoke purification channel. The smoke supplying device comprises an aerosol generator, an air distributing device, a gas cylinder and an ozone generator. The gas cylinder and the ozone generator are both connected to the air distributing device. After being connected to the aerosol generator in a parallel manner, the air distributing device feeds into the original-smoke channel. The test platform is capable of providing various flue gas compositions, dust concentrations and voltage and current conditions, simulating corrosion processes of the filtering materials in complex environment, and carrying out performance tests for the filtering materials under conditions of different dust concentrations and with/without discharging. In addition, real-time monitoring and data recording can be performed for test parameters comprising component concentrations, dust concentrations, test resistance, etc. in corrosion test processes, and dynamic filtering performances of the filtering materials after corrosion can be tested.

Description

technical field [0001] The invention belongs to the field of filter material performance testing devices, and in particular relates to a multifunctional filter material corrosion resistance testing platform. Background technique [0002] With the increasing emphasis on energy conservation and emission reduction, the state has become increasingly strict and specific on the emission standards of air pollutants in various industries. In the national standard GB / T 13223-2011 "Emission Standards of Air Pollutants for Thermal Power Plants", the dust emission concentration of new thermal power plant projects is strictly required to be 30mg / m 3 . Not only that, the frequent occurrence of PM2.5 pollution in recent years has made the country strengthen the control of power plant smoke and dust emissions. Therefore, in order to meet the requirements of low pollutant emission concentration and control the emission of fine dust, more and more power plants use bag filter or electric bag...
