Sampling device for industrial waste gas detection

Abstract

The invention discloses a sampling device for industrial waste gas detection. According to the technical scheme, the sampling device comprises a box body, an air pipe is rotationally arranged in the box body, one end of the air pipe communicates with a branch pipe, the two ends of the branch pipe are connected with gas collecting assemblies, a collecting box communicating with the air pipe is arranged in the box body, an air exhaust assembly is connected to the side wall of the collecting box, and a driving assembly used for driving the air pipe to rotate is further arranged in the box body; the air exhaust assembly comprises an air pump, an air inlet of the air pump communicates with the collecting box, an air outlet of the air pump is connected with an air outlet pipe, and the air outletpipe extends out of the box body and is connected with a storage device; the driving assembly comprises a hose connected to the air pump and an air gun connected to the hose; an air receiving plate is arranged on the side wall of the air pipe, an air nozzle of the air gun faces the air receiving plate, and when the air gun sprays air to the air receiving plate, the air pipe is stressed to rotate;an elastic reset assembly used for driving the air pipe to rotate reversely so as to reset the air pipe is further arranged in the box body. The technology has the advantage that gas sampling can beconveniently carried out at multiple point positions at a time.

Description

technical field [0001] The invention relates to the field of industrial exhaust gas detection, more specifically, it relates to a sampling device for industrial exhaust gas detection. Background technique [0002] With the continuous development and progress of our country's social economy, the problem of ambient air pollution is becoming increasingly serious. Among them, industrial waste gas is the main source of air pollutants. In environmental protection work, the role of industrial waste gas detection data cannot be ignored, and it is an important basis for environmental protection work. [0003] In the prior art, general industrial exhaust gas sampling devices usually use single-point sampling, and the sampling range is small. In order to improve sampling accuracy, it is usually necessary to perform multiple multi-point sampling. This sampling method is relatively cumbersome. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpos...
