Abstract

The invention discloses an automatic sampling device for gas detection, which comprises a bottom supporting device, an inserting opening is formed in the bottom supporting device, a pushing and pressing device is arranged above the inserting opening, a telescopic device is arranged below the inserting opening, a sampling needle is arranged on the telescopic device, and the tail end of the sampling needle is connected with a gas guide pipe. The upper surface of the bottom supporting device is movably connected with a sample turntable, a sample tube is detachably connected in the sample turntable, and the sample turntable is connected with a power device. The device can effectively solve the problem that the labor cost and the sampling cost are increased due to the fact that an existing device cannot automatically inject samples.

Description

technical field [0001] The invention belongs to the technical field of sample injectors, and in particular relates to an automatic sample injection device for gas detection. Background technique [0002] In 2018, the State Council issued the "Notice on Printing and Distributing the Three-Year Action Plan for Winning the Blue Sky Defense War" ([2018] No. 22). The notice pointed out that it is necessary to implement a special rectification plan for VOCs, study the inclusion of VOCs in the scope of environmental protection taxation, and carry out monitoring of ambient air VOCs in cities in key areas and other cities with serious ozone pollution. Strict environmental law enforcement inspections, carry out grid supervision of air pollution hotspots in key areas, and strengthen environmental law enforcement such as industrial furnace emissions, industrial unorganized emissions, and VOCs pollution control. Among them, VOCs use TVOC and non-methane total hydrocarbons as control ind...
