Description
Technical field
The present invention relates to the exhaust-gas treatment field that properties of product test produces is and in particular to a kind of acid mist of salt mist tester
Processing meanss.
Background technology
The ability of the salt air corrosion of salt spray test chamber test material and its overcoat, and the processing quality of similar overcoat
Relatively；The ability of some product salt fog resistance corrosion can be tested simultaneously；This proof box is applied to parts, electronic component, metal material
The overcoat of material and the salt spray corrosion test of industrial products.
General salt spray test chamber is all directly test product to be put into inner chamber to be tested, and salt spray test is divided into neutral salt
Mist and acid two kinds of salt fog, for acid salt spray test, so far, are all directly to empty the salt fog of generation, experimenter
Be in for a long time in experimental enviroment, open every time the upper lid of salt spray test chamber inevitably directly with acid salt fog intimate contact,
Substantially, the acid ingredient in acid salt spray test is mainly hydrochloric acid, and hydrochloric acid is a kind of strong acid, and its corrosivity is big, can be strong
Stimulate the breathing mucosa of people, eyes, corneal clouding, hoarse, sensation of asphyxia, chest pain, rhinitis, cough occur when serious, has
When sputum mixed with blood, salt acid mist may result in a facial skin to have an intense pain nose etc., and hydrochloric acid itself and acid mist all can corrode human body group
Knit, may irreversibly damage respiratory apparatus, eye, skin and gastrointestinal etc., if so not to ackd salt in salt spray test chamber
Mist is processed, it will greatly have impact on the working environment of experimenter.
Content of the invention
The invention provides a kind of acid mist treatment device of salt mist tester, it is connected with salt mist tester, absorb salt fog examination
Test the acid salt fog producing in machine, solve the poor working environment causing because of the acid salt fog in salt spray test chamber in prior art
Problem.
For solving above-mentioned technical problem, the present invention employs the following technical solutions:
A kind of acid mist treatment device of salt mist tester, is arranged on salt mist tester including acid mist treatment trough and air inlet
The air exhauster of box house, described acid mist treatment trough, built with alkali liquor, is provided with agitating device in described alkali liquor, described air exhauster
Discharge pipe is located at acid mist treatment trough, after acid salt spray test finishes, opens air exhauster, by the acid mist in salt spray test cabinets cavity
Suck in acid mist treatment trough, then open agitating device so that acid mist is fully neutralized with alkali liquor, thus absorbing in salt mist tester
The acid salt fog producing, eliminates acid salt fog, it is to avoid the direct emptying of acid smog, efficiently solve in prior art because
The problem of the poor working environment that the acid salt fog in salt spray test chamber causes.
Further, below the liquid level of acid mist treatment trough is stretched into so that acid salt fog and acid in the bottom of described discharge pipe
