Example Embodiment

[0020] Example 1

[0021] like figure 1 As shown, a solid adsorption device for the waste gas of a salt spray testing machine includes an acidic smoke adsorption box 1 and a first exhaust fan 2. The acidic smoke adsorption box 1 is composed of an upper cover 12 and a box body 11 arranged up and down. The box body 11 is equipped with an adsorbent 111, and a buffer layer 112 is arranged above the adsorbent 111; the upper cover 12 is provided with a vent pipe 14, and the first exhaust fan 2 includes an air inlet pipe 21 and an air outlet pipe 22. The air inlet pipe 21 is connected to the inner cavity of the salt spray testing machine, the outlet of the air outlet pipe 22 is set at the bottom of the box body 11, and the outlet of the air outlet pipe 22 is provided with a cotton ball 221 .

[0022] The operation steps of this embodiment are: after the acid salt spray test in the salt spray test chamber is completed, the first exhaust fan 2 is turned on, and the acid smoke in the i...

Abstract

The invention discloses a solid adsorbing device for exhaust gas of a salt mist testing machine, and relates to the field of treatment to the exhaust gas generated during a product performance test. The solid adsorbing device comprises an acidic salt mist adsorbing tank and a first exhaust fan, wherein the acidic salt mist adsorbing tank consists of an upper cover and a tank body which are arranged up and down; the tank body is filled with an adsorbent; a buffer layer is arranged above the adsorbent; an emptying pipe is arranged on the upper cover; the first exhaust fan comprises an intake pipe and a discharge pipe; the intake pipe is connected with an inner cavity of the salt mist testing machine; an outlet of the discharge pipe is formed in the bottom of the tank body; a cotton ball is arranged at the outlet of the discharge pipe. After an acidic salt mist test, the exhaust fan is turned on to suck acidic salt mist in the inner cavity of a salt mist test tank body into the acidic salt mist adsorbing tank, and the adsorbent in the acidic salt mist adsorbing tank adsorbs acidic components in the acidic salt mist to avoid direct emptying of the acidic salt mist, so that the problem of a poor working environment caused by the acidic salt mist in a salt mist test tank in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the field of waste gas treatment generated from product performance testing, in particular to a solid adsorption device for the waste gas of a salt spray testing machine. Background technique [0002] The salt spray test chamber is used to test the salt spray corrosion ability of materials and their protective layers, as well as the process quality comparison of similar protective layers; at the same time, it can test the ability of some products to resist salt spray corrosion; the test chamber is suitable for parts, electronic components, Protective layer of metal materials and salt spray corrosion test of industrial products. [0003] The general salt spray test chamber is to directly put the test product into the inner cavity for testing. The salt spray test is divided into two types: neutral salt spray and acid salt spray. The fog is directly emptied, and the experimenters have been in the test environment for a long time....
