Embodiment 1

[0023] like figure 1 As shown, an acid mist treatment device for a salt spray test machine includes an acid mist treatment tank 1 and an exhaust fan 2 whose air inlet is arranged inside the salt spray test machine box. The acid mist treatment tank 1 is equipped with lye. A stirring device 3 is provided in the lye, and the air outlet pipe 21 of the exhaust fan 2 is arranged in the acid mist treatment tank 1 .

[0024] The operation steps of this embodiment are: after the acid salt spray test in the salt spray test chamber is completed, turn on the exhaust fan 2 and keep it for 3-5 minutes until all the acid mist in the inner cavity of the salt spray test chamber is sucked into the acid mist treatment tank 1, then turn on the stirring device 3 to fully neutralize the acid mist and lye, and finally turn on the salt spray test chamber.

[0025] A pH detector is installed in the inner cavity of the salt spray test chamber to detect whether all the acid mist in the inner cavity of ...

Embodiment 2

[0028] like figure 2 As shown, it is further optimized on the basis of the acid mist treatment device of a salt spray tester described in Example 1, the air outlet pipe 21 of the exhaust fan 2 extends below the liquid level of the lye, and the air outlet The pipe 21 is provided with a fixed block 211, a floating block 212, and a fixed sieve plate 213 sequentially from top to bottom, the fixed block 211 is fixed inside the air outlet pipe 21, the floating block 212 is cylindrical, and the diameter of the floating block 212 The gap distance greater than that of the fixed block 211 is smaller than the inner diameter of the air outlet pipe 21 , and the fixed sieve plate 213 is fixed inside the air outlet pipe 21 , and several through holes are provided on the fixed sieve plate 213 .

[0029] In this embodiment, the bottom of the air outlet pipe 21 extends into the setting below the liquid level of the acid mist treatment tank 1 so that the acidic salt mist fully contacts with the...

Embodiment 3

[0031] On the basis of the acid mist treatment device of a salt spray tester described in Example 1, it is further optimized. The acid mist treatment tank 1 is provided with a pH detection device, and the top of the acid mist treatment tank 1 is provided with a lye storage The tank 4, the pipeline between the acid mist treatment tank 1 and the lye storage tank 4 is provided with an lye control valve 41, and the bottom of the acid mist treatment tank 1 is provided with a treatment liquid control valve 9.

[0032]The operation steps of this embodiment are: when the pH detection device detects that the pH value of the treatment liquid in the acid mist treatment tank 1 is less than 7.5, open the treatment liquid control valve 9, discharge the treatment liquid in the acid mist treatment tank 1, and then Close the treatment liquid control valve 9, open the lye control valve 41, close the lye control valve 41 until suitable new lye is loaded into; When the value is less than 7.5, the...

Abstract

The invention discloses an acidic mist treating device of a salt mist tester and relates to the field of treatment of waste gas generated during product performance testing. The acidic mist treating device comprises an acidic mist treating tank and an air extractor with an air inlet arranged inside a salt mist tester box, alkaline liquid is contained in the acidic mist treating tank, a stirring device is arranged in the alkaline liquid, and an air outgoing pipe of the air extractor is arranged in the acidic mist treating tank. After an acidic salt mist test is finished, the air extractor is started to suck acidic mist in an inner cavity of the salt mist tester box into the acidic mist treating tank, and then the stirring device is started to enable acidic mist and the alkaline liquid to be fully neutralized, so that the acidic salt mist generated in the salt mist tester is absorbed, the acidic salt mist is eliminated and avoided being directly discharged into air, and the problem of poor working environment caused by the acidic salt mist in the salt mist tester box in the prior art is solved effectively.

Description

technical field [0001] The invention relates to the field of waste gas treatment generated in product performance testing, in particular to an acid mist treatment device for 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. Every time the...
