Description

Intelligent radon-removing daughter air purifier

Technical Field

The utility model relates to an air purification device field especially relates to an intelligence radon removal daughter air cleaner.

Background

Radon daughter, natural radioactive gas radon²²²And Rn is radiated to decay to generate a short-lived daughter. Radon (Radon)²²²Rn radiative decay generation²¹⁸The amount of the Po sub-body,²¹⁸successive generation of Po daughter bodies by continued decay²¹⁴Pb、²¹⁴Bi、²¹⁴Po and²¹⁰pb, etc. due to²¹⁰The half-life of Pb is as long as 22.3a, and basically can be regarded as a stable daughter nuclide, and²¹⁰pb and its subsequent daughter hardly reach measurable radioactive concentrations in air. Therefore, the radon daughter is specially used for constituting radiation threat to human body²¹⁸Po、²¹⁴Pb、²¹⁴Bi and²¹⁴four types of short-lived daughter, Po.

The decay daughter generated by decay of the parent to form clusters surrounded by polar substances in the air is called as unbound radon daughter, the particle size is usually between 0.5nm and 5nm, the decay daughter has extremely strong diffusion and adsorption capacity, and the decay daughter is easy to collide and adsorb with aerosol particles in the air to form bound radon daughter, and the particle size is usually between 50nm and 2000 nm. The majority of radon daughter exists in radioactive aerosol generated by combining with fine particles with the particle size less than 2 μm in air, wherein the proportion of the radon daughter in an unbound state is very low, and is usually between 5% and 13%.

Radon (Radon)²²²Rn is inert gas, 95% of Rn is discharged along with the exhaust gas after being inhaled into a human body, and the radiation damage to the human body is negligible. The radon daughters have strong diffusivity and adhesiveness, are easy to be intercepted by respiratory tracts after being inhaled into human bodies and are continuously deposited on the tracheal walls and the surfaces of alveoli in the form of metal particles. Meanwhile, alpha particles generated by decay of radon daughters have high energy, so that tissues or cells damaged by radiation can be ionized, the molecular structure of DNA in the cells is damaged or changed, the replication function of the DNA is inhibited, abnormal cell division is caused, and finally lung cancer is induced. In fact, over 95% of the mean effective dose of indoor radiation is contributed by radon daughter, wherein the concentration of unbound radon daughter, which accounts for only 5% -13%, contributes 30.22% -46.24% of the total radiation dose. Therefore, the radon eliminating daughter has more practical significance than radon eliminating daughter, and the key point of radon eliminating daughter is to eliminate the radon daughter in an unbound state.

The existing radon-removing daughter air purifier is not widely applied in the market and mainly has the following two problems:

1. the existing radon-removing air purifier can monitor the indoor radon concentration change in real time and check the radon-removing capability of the radon-removing air purifier only through a radon-concentration detector, but the radon-removing air purifier does not have the real-time monitoring capability on the indoor radon concentration, and indoor personnel cannot know the indoor radon concentration level through the radon-removing air purifier and need other equipment for assistance;

2. the radon removal effect is poor in high radon areas, most of the existing radon removal air purifiers adopt an electrostatic-filtration purification mode, and the mode mainly plays a role in purifying large-particle-size radon and has no obvious effect on the purification of small-particle-size radon. For example, after the radon removal air purifier in a certain two underground projects is started and runs stably, the radon concentration of the radon removal air purifier is reduced from 933Bq/m3 to 163.8Bq/m3, the reduction amplitude reaches 82.4 percent, and the radon removal air purifier is reduced from 2160Bq/m3 to 322Bq/m3, the reduction amplitude reaches 85.1 percent. The former and later comparisons show that the radon daughter eliminating rate of the latter is improved, but the radon daughter controlling level is greatly reduced, and the radon daughter eliminating rate exceeds the dose equivalent limit value 5mSv allowed to be accepted by the general residents, which is set by the international atomic energy agency, so that the radon daughter eliminating rate of the latter is still obviously harmful to the human body.

Therefore, in order to attach importance to the safety of working and living environments of personnel in radon-polluted areas, it is necessary to provide an intelligent radon-removing air purifier which can monitor the radon daughter concentration in real time, remove radon daughter efficiently and control the radon daughter concentration below a safety line for a long time.
