Embodiment 1

[0032] like Figure 1-6 As shown, the present invention provides an air pollution gas detection system, including a gas collection shell 1, the left and right sides of the gas collection shell 1 are embedded with an intake pipe 2 and an exhaust pipe 3, and the right end of the intake pipe 2 is detachably connected There is a sealing cover 21, the exhaust pipe 3 extends in the inner cavity of the gas collection shell 1, and the left end of the exhaust pipe 3 is provided with a negative pressure pump 4, and the center of the inner cavity of the gas collection shell 1 is provided with a constant potential electrolytic sensor 6, And the inner cavity of the gas collection shell 1 is provided with a guide frame 5 on the right side. When the air pollution gas detection system is in operation, the sealing cover 21 connected to the right end of the intake pipe 2 is disassembled, and the left end of the control exhaust pipe 3 is provided with a The negative pressure pump 4 works so that...

Embodiment 2

[0035] like Figure 1-6As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the left and right ends of the arc-shaped fixing frame 51 are horizontally provided with a circulation groove-8, and the circulation groove-8 is connected with the arc-shaped groove 7 Interconnected, the side of the connecting frame body 521 close to the constant potential electrolytic sensor 6 is provided with a flow tank 2 10, the center of the inner wall of the flow tank 10 is provided with a filter 11, and the right side of the inner wall of the flow tank 10 is provided with a sponge Adsorption cushion layer 12, in the process of gas discharge, the gas needs to pass through the particle collection frame 52 in the shape of an arc, and the filter screen 11 and the sponge adsorption cushion layer 12 arranged in the circulation groove 2 10 provided on the surface of the particle collection frame 52 respectively The particles and dust mixed in the gas ...

Embodiment 3

[0038] like Figure 1-6 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the left and right sides of the inner wall of the limiting groove 15 are all embedded with a magnetic block 17, and the left and right sides of the outer surface of the collection box 16 are both Embedded with two magnetic blocks 18, the magnetic poles of the first magnetic block 17 and the second magnetic block 18 are opposite to each other, and the tops on the left and right sides of the inner wall of the limit groove 15 are movably connected with a single guide vane 20 by setting a limit rotating shaft 19. When the filter screen 11 drives and connects the sponge adsorption pad 12 to bounce, the particles and dust adhering to the surface vibrate and enter the collection box 16 installed inside the limiting groove 15, and the filter screen 11 and the sponge adsorption pad The layer 12 has a cleaning effect, and the magnetic force connection between ...

Abstract

The invention discloses an atmospheric pollution gas detection system, and relates to the technical field of environment detection, the atmospheric pollution gas detection system comprises a gas collection shell, each of the left and right sides of the gas collection shell is embedded with a gas inlet pipe and an exhaust pipe, the right end of the gas inlet pipe is detachably connected with a sealing cover, and the exhaust pipe extends into the inner cavity of the gas collection shell. A negative pressure pump is arranged at the left end of the exhaust pipe, a constant potential electrolysis sensor is arranged at the center of an inner cavity of the gas collection shell, a flow guide frame is arranged in the position, close to the right side, of the inner cavity of the gas collection shell, the flow guide frame is located on the left side of the exhaust pipe, and the flow guide frame comprises an arc-shaped fixing frame and a particle collecting frame. The sampling workload is reduced, meanwhile, the atmosphere sampling capacity is increased, adhesion of particulate matter and dust in the gas collecting shell is effectively reduced, the particulate matter and the dust can enter the collecting box in an oscillating mode, and the situation that external pollutants enter the gas collecting shell to affect the constant potential electrolysis sensor is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to an air pollution gas detection system. Background technique [0002] Atmospheric pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, present a sufficient concentration and reach sufficient time, and thus endanger the comfort, health and welfare of the human body or the environment. Air pollutants are caused by human sources. Or natural sources enter the atmosphere (input), participate in the circulation process of the atmosphere, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities and physical deposition in the atmosphere (output). If the output rate is less than the input rate, it will be relatively concentrated in the atmosphere, resulting in an increase in the concentration of a certain substance in the atmosphere. When the con...
