Embodiment 1

[0029] refer to Figure 1-2 , a sampling device for air pollution prevention and control, comprising a base 1, one side of the top of the base 1 is fixedly connected with a slide rail 2, and one side of the slide rail 2 is slidably connected with a lifting platform 4, and the top of the lifting platform 4 is fixedly connected with an air pump , and the suction end of the air pump is provided with an air suction pipe 5, the exhaust end of the air pump is provided with a hose 9, and one side of the top of the base 1 is fixedly connected to a gas collection box 15, and the bottom end of the hose 9 is fixedly connected to The middle position of the top of the gas collection box 15, and the connection between the hose 9 and the gas collection box 15 is fixedly connected with a one-way vent valve 11, and one side of the top of the gas collection box 15 is provided with a water supply pipe 13, and the middle part of the water supply pipe 13 A first valve 14 is provided, a drainage pi...

Embodiment 2

[0037] refer to Figure 3-4 , a sampling device for air pollution prevention and control. Compared with Embodiment 1, the end of the air extraction pipe 5 away from the air extraction pump is fixedly connected with a dust collecting bucket 19, and the inner wall of the dust collecting bucket 19 is fixedly connected with a filter screen 20. The inner wall of the middle part of the dust hopper 19 is welded with an iron ring 22 , and one side of the filter screen 20 is attached to the iron ring 22 , and the other side of the filter screen 20 is provided with a magnetic ring 21 .

[0038] Working principle: The solid particles in the air sample are retained through the filter screen 20 to avoid blocking the air pump, and the filter screen 20 is fixed by the adsorption of the magnetic ring 21 and the iron ring 22, which is convenient for disassembly and cleaning of the filter screen 20. Moreover, it is convenient for the staff to collect the solid particles in the sample.

Abstract

The invention discloses atmospheric pollution prevention and treatment sampling equipment which comprises a base, a sliding rail is fixedly connected to one side of the top of the base, a lifting table is slidably connected to one side of the sliding rail, an air extracting pump is fixedly connected to the top of the lifting table, an air extracting pipe is arranged at the air extracting end of the air extracting pump, and a hose is arranged at the exhaust end of the air extracting pump. When the device is used, the device is used, the gas collecting tank is filled with water through the wateradding pipe; air in the air collecting box is exhausted; the first valve is closed after water is added; the communication between the gas collecting box and the external atmosphere is separated; opening the second valve, the air extracting pump extracts air through an air extracting pipe; a gas sample enters the gas collecting box through the hose, water in the gas collecting box is pressed outthrough the water discharging pipe, the water level in the gas collecting box is monitored through the observation window, when the water is completely discharged, the sucking pump and the second valve are closed, sample collection is completed, and the one-way vent valve can guarantee that the sample in the gas collecting box cannot escape through the hose.

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] At present, atmospheric sampling refers to the method of collecting pollutant samples or polluted air samples in the atmosphere. One type of collection method is to pass a large amount of air through a liquid absorbent or a solid adsorbent to enrich the pollutants with a lower concentration in the atmosphere. Such as pumping method, membrane filtration method. The other is to use containers to collect air containing pollutants. [0003] After searching, the Chinese Patent Publication No. is CN208805398U, which discloses a sampling device for air pollution prevention and control, including a base. The top of the base is fixedly equipped with a tank with an opening on one side, and a push plate is installed in the tank for sliding sealing. The sampling equipment for air pollution preventio...
