Rapid low-humidity explosion tank device for static safety detection

Abstract

The invention discloses a rapid low-humidity explosion tank device for static safety detection, comprising an anti-explosion tank body and a sealing cover at the upper part of the tank body; the inner part of the anti-explosion tank body is provided with a molecular sieve, the inner part of the anti-explosion tank body is further provided with an isolating sieve; a static discharge pillar is installed in the isolating sieve, a humidity sensor and an air changing channel are arranged on the sealing cover; a part of a static discharging pillar is located in the isolating sieve, and a part is extended out of the outer part of the sealing cover. The two dehumidifying methods of the molecular sieve and the vacuumizing are carried out at the same time, thus the dehumidifyin speed is quick, and the lowest humidity can be reached. The humidity can rapidly reach about 10% RH level, and realize the extreme low humidity for the test. An isolating sieve can stop breaking pieces generated from the explosion, and protect the molecular sieve. The anti-explosion tank body can bear a certain TNT equivalent explosion.

Description

technical field [0001] The invention relates to a humidity control device, in particular to a fast low-humidity explosion tank device suitable for electrostatic safety detection. Background technique [0002] Traditional humidity control devices mainly use vacuum pumping and moisture absorption for dehumidification. [0003] At present, the humidity control devices available on the market can only meet the minimum humidity requirements of about 30% RH, and it is difficult to meet the conditions of extremely low humidity such as less than 10% RH, and these devices generally do not have explosion-proof requirements, so it is difficult to apply to explosives and Research on the electrostatic safety of pyrotechnics also cannot achieve rapid dehumidification. [0004] In summary, most of the traditional humidity control devices have the following disadvantages: [0005] 1. The dehumidification speed is slow. [0006] 2. The minimum humidity that can be achieved is not low enou...
