Sampling equipment for preventing and controlling atmospheric pollution

Abstract

The invention relates to the technical field of air sampling, in particular to air pollution prevention and control sampling equipment which comprises a shell and a plurality of air storage bottles, first through holes communicated with inner cavities of the air storage bottles are formed in the upper surfaces of the air storage bottles, piston blocks are slidably connected into the inner cavities, second through holes communicated with the inner cavities of the air storage bottles are formed in the bottom surfaces of the air storage bottles, and the piston blocks are slidably connected into the second through holes. A blocking hole transversely penetrating through the second through hole is formed in the side face of the lower portion of the gas storage bottle. The front side surface of the shell is provided with a mounting groove for arranging and mounting a plurality of gas storage bottles in parallel; an in-place detection sensor is arranged on the top surface, corresponding to the first through hole, of the mounting groove; an air outlet communicated with the second through hole is formed in the bottom surface, corresponding to the second through hole, of the mounting groove; an air inlet power assembly, a pipeline valve assembly, an air storage cylinder sealing assembly and a control assembly are arranged in the shell. The problems that an existing air sampler is single in air sampling direction and inconvenient to carry and use due to the fact that the extraction mode is single and cannot be adjusted and controlled are solved.

Description

technical field [0001] The invention relates to the technical field of air sampling, in particular to an air pollution prevention and control sampling device. Background technique [0002] Air pollution refers to the pollution caused by certain substances entering the atmosphere due to human activities or natural processes. For example, sulfur dioxide, nitrogen oxides, volatile organic compounds, ammonia, smoke, dust and other pollutants discharged into the atmosphere caused by the combustion of coal and other energy, industrial production, transportation, construction, open-air burning of straw, and setting off fireworks and firecrackers Air Pollution. When the concentration of these substances reaches a harmful level, it will damage the ecosystem and cause harm to people or things. For example, smog and haze were common in northern winter in previous years, and the respiratory diseases caused by it. [0003] Judging whether the atmosphere is polluted needs to be confirm...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sampling device for the prevention and control of air pollution, which solves the problem that the extraction mode of the current air sampler is single and uncontrollable, resulting in a single orientation of air sampling and inconvenient portability and use.
