Embodiment 1

[0046] This embodiment provides a wet wall type gas detection device, the structure of which can be found in figure 1 and figure 2 As shown, including the water tank 4, and the detection test paper 2 and the water diversion cotton core 3 arranged inside the water tank 4, an air inlet 1 and an exhaust port 6 are respectively provided on the opposite sides of the top of the water tank 4, so that in the water tank 4 A gas flow cavity that is located above the liquid surface and passes through the position of the detection test paper 2 is formed inside. One end of the water diversion cotton core 3 is in contact with the detection test paper 2, and the other end is placed below the liquid surface of the water tank 4.

[0047] see you again figure 1 As shown, the inside of the water tank 4 is also provided with three partitions 8, and divides the gas flow cavity into four detection compartments 10 connected in sequence along the gas flow direction, which are respectively labeled A...

Abstract

The invention relates to a wet wall type gas detection device which comprises a water tank, detection test paper and a water diversion cotton core. The detection test paper and the water diversion cotton core are arranged in the water tank, and a gas inlet and a gas outlet are formed in the two opposite sides of the top of the water tank respectively, so that a gas flowing cavity which is located above the liquid level of the water tank and passes through the position where the detection test paper is located is formed in the water tank; one end of the water diversion cotton core is in contact with the detection test paper, and the other end of the water diversion cotton core is arranged below the liquid level of the water tank. Compared with the prior art, the device is simple in structure, low in cost, good in safety and mobility, capable of directly and rapidly determining the type and danger of gas and convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of gas detection and relates to a wet wall type gas detection device. Background technique [0002] In recent years, accidents such as leaks and explosions of toxic and harmful gases (such as hydrogen sulfide, ammonia, and chlorine) have occurred frequently, which not only threaten the personal safety of workers, but also cause environmental pollution. As a result, various gas detection tubes were born, which have the advantages of simple and fast detection methods, small sampling volume, short response time, portability, and high sensitivity. It is a qualitative and semi-quantitative detection method. In the coal mine and petrochemical industry, most of the flammable and explosive gases, toxic gases and asphyxiating gases exist, and the use of gas detection tubes can quickly and accurately detect toxic and harmful gases in the air. Gas detection tubes can be used for environmental monitoring such as air an...
