Problems solved by technology

[0004] 1. Most of the existing radioactive pollutants are collected through sampling sheets to collect radioactive pollutants in the air, and then the sample sheets are tested at the position of transfer to the detection, which will cause the pollutants on the sample sheets to fall off and affect the detection results
[0005] 2. Traditional physical adsorption heat-resistant radioactive pollution purification monitoring equipment can only perform routine measurement of radioactive pollutants, but cannot eliminate radioactive pollutants, making radioactive pollutants reach safe values

Embodiment 1

[0046] Example 1: Measure the radioactive radon in the environment.

[0047] Specifically, place a new conductive sampling glass 45 on the upper wall of the opening of the detection box 36, turn the bolt 42, and the bolt 42 rotates along the threaded opening 41 to fit the conductive sampling glass 45, so that the conductive sampling glass 45 is fixed on the conductive post 44 and the conductive sampling glass 45. Between the bolts 42, the delivery control valve 47 and the mixing outlet valve 39 are manually closed, the delivery pipe 8 and the mixing pipe 38 are blocked and cut off, and the shunt inlet valve 48 is manually opened to make the shunt pipe 37 conduct, and the controller 50 controls the negative pressure fan 7 starts, the negative pressure fan 7 draws the outside air into the shunt box 2, and the air inside the shunt box 2 enters the inside of the detection box 36 through the shunt pipe 37. At this time, the controller 50 controls the electrostatic generator 43 to st...

Embodiment 2

[0048] The second embodiment, based on the above-mentioned embodiment, purifies the air environment with a high concentration of radioactive pollutants after detection.

[0049] Specifically, the shunt inlet valve 48 is manually closed, the shunt pipe 37 is blocked and cut off, and the delivery control valve 47 and the mixing outlet valve 39 are manually opened to make the delivery pipe 8 and the mixing pipe 38 conduct. In the closed state, the exhaust pipe 15 is blocked and cut off, the controller 50 controls the negative pressure fan 7 to start, and the negative pressure fan 7 draws the gas in the environment to be monitored into the shunt box 2, and the shunt box 2 transports the gas through the conveying pipe 8 To the inside of the separation box 20, the air flow inside the conveying pipe 8 generates a negative pressure around it when it flows at a high speed, so that the conveying pipe 8 draws the gas inside the detection box 36 into the separation box 20 through the mixin...

Description

technical field [0001] The invention belongs to the technical field of pollution monitoring equipment, in particular to a physical adsorption anti-heat type radioactive pollution purification type monitoring equipment. Background technique [0002] Radon is the only natural radioactive rare gas. There are two main hazards of radon to human health, namely internal radiation and external radiation. At room temperature, radon and its daughters can form radioactive aerosols in the air and pollute the air. Because it is colorless Odorless and easily overlooked, it is easily retained by the respiratory system and accumulates in localized areas. Long-term inhalation of high concentrations of radon can eventually induce lung cancer. [0003] At present, the existing physical adsorption heat-resistant radioactive pollution purification monitoring equipment has the following problems: [0004] 1. Most of the existing radioactive pollutants collect radioactive pollutants in the air t...
