Abstract

The invention relates to a gas detection device, in particular to a preliminary qualitative gas detection device for chemical plants. The preliminary qualitative gas detection device for the chemical plants is high in detection precision, simple in structure and capable of accurately judging gas properties. The preliminary qualitative gas detection device for the chemical plants comprises a bottom plate, a box, a motor, a gear, a rack, a connecting rod, a left piston, a baffle, a right piston, a gas inlet pipe, a first valve, a first check valve, a gas outlet pipe and the like, wherein the box, the first detection pipe and the second detection pipe are sequentially arranged at the top of the bottom plate from left to right, and the baffle is arranged in the middle of the top of the box. Gas in the air is detected by a phenolphthalein solution and a litmus solution, either excessive acid gas or alkaline gas discharged from the chemical plant can be judged preliminarily, and accordingly, the follow-up work can be omitted.

Description

technical field [0001] The invention relates to a gas detection device, in particular to a gas preliminary qualitative detection device for a chemical plant. Background technique [0002] Gas refers to a deformable and flowable fluid with no shape and volume. A gas is a state of matter. A gas is a fluid like a liquid: it can flow, it can deform. Unlike liquids, gases can be compressed. If there is no restriction (container or force field), the gas can diffuse and its volume is not restricted. The atoms or molecules of a gaseous substance can move freely with respect to each other. The kinetic energy of atoms or molecules of gaseous substances is relatively high. The gas form can be affected by its volume, temperature and its pressure. These elements constitute a number of gas laws, and the three can influence each other. [0003] Detection refers to the use of specified methods to test the specified technical performance indicators of an object (gas, liquid, solid). ...
