Embodiment Construction

[0029] In order to make the objects, technical solutions and advantages of the present invention clearer, the following in conjunction with specific examples and with the accompanying figure 1 The present invention is further described in detail.

[0030] figure 1 It is an embodiment of the present invention.

[0031] The clean air supply device is composed of an air compressor, a drying and purifying pipe, and a pressure stabilizing valve. The dilution and carrying air is generated by the air compressor, and then enters the corrosion generating device through A, B, C, and D after passing through the pressure stabilizing valve and the drying and purifying pipe.

[0032] Path A passes through the flow meter and pressure gauge with a needle valve and enters the corrosion test reaction device as a secondary dilution gas source. Routes B, C, and D respectively carry the diffused substance in the flue and solution bottle to the sample corrosion test reaction device through the f...

Abstract

The invention discloses a test box for simulating the corrosion of a PM2.5 (particulate matter 2.5) polluted environment, which belongs to the technical field of material corrosion and reliability evaluation. The test box comprises a clean air supply device, a pollution source generating device, a particulate matter screening device, a sample corrosion test reaction device, a particulate matter collection device and a pollutant adsorption device. By adopting the test box, the PM2.5 pollution source is controlled, and the temperature-controlled, humidity-controlled and multi-path pollution source of the dynamics diameter of the PM2.5 pollution source can be controlled. The test box has the advantages that the floor occupation area is small, the structure is simple, convenience in operation is realized, the pollution is small, the temperature, the humidity and the pollution source are proportionally and simultaneously controlled, and the test box is applicable to the scientific research and the engineering test research.

Description

technical field [0001] The invention belongs to the technical field of material corrosion and reliability detection, and in particular provides a PM-containing 2.5 Particle pollution gas, to meet the simulated PM 2.5 Experimental setup for corrosion behavior and reliability testing of polluted gases. Background technique [0002] Atmospheric particulate matter (PM) is the general term for solid and liquid particulate matter in the atmosphere. According to its particle size, it can be divided into coarse dispersion system (particle size greater than 10 μm) and colloidal dispersion system (0.001 ~ 10 μm) PM l0 Refers to particles with an aerodynamic diameter of 10 μm. The results of the analysis show that PM in large cities 2.5 The main source is vehicle exhaust, especially diesel vehicle exhaust. PM 2.5 Can adsorb a wide variety of toxic chemicals. PM in North China and East China 2.5 In heavily polluted areas, the annual average concentration is 60-80mg / m 3 . The p...
