Abstract

The invention discloses a comprehensive test system of a regenerable toxicity filtering ventilation device, which comprises the regenerable toxicity filtering ventilation device and a test gas input pipeline. The regenerable toxicity filtering ventilation device is composed of a freezing dryer, a first-stage filter, a second-stage filter, a first check valve, a second check valve, a third check valve, a fourth check valve, a waste gas tank, a first filtering absorber, a second filtering absorber, a two-way valve, a fifth check valve, a sixth check valve, a flow adjusting valve and a gas storage tank. The test gas input pipeline is composed of a compressor, a stabilizing gas tank, a flow controller, a gas water separator, a mixed gas tank, a flow controller, a cyan chloride liquid storage tank and a stabilizing gas tank. The comprehensive test system can test not only the regenerable toxicity filtering ventilation device but also other toxicity filtering ventilation devices to evaluate the protection performance of the toxicity filtering ventilation device.

Description

technical field [0001] The invention relates to the technical field of nuclear, biological and chemical protection, in particular to a test system for testing a regenerable poison filter ventilation device. Background technique [0002] The so-called comprehensive test system of the renewable poison filter ventilation device refers to the device that the system can test the filtration and purification performance of the renewable poison filter ventilation device. The regenerative filter ventilation unit recirculates and filters the air to provide clean air to those inside the cabin or bunker. [0003] At present, there is a lack of testing systems capable of testing the filtration and purification performance of regenerative filtration ventilation devices. In order to assess the reliability of the regenerative poison filter ventilation device and evaluate its protective performance, it is necessary to develop a comprehensive test system for the regenerative poison filter ve...
