Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to a radon daughter particle purifier. Background Art

[0002] Radon is the only radioactive gas that exists naturally in nature. It is colorless and odorless, and accumulates unnoticed in the air where people live and work. It is produced during the decay of radioactive elements such as uranium and thorium, so granite, apatite and diabase rich in uranium and thorium are rich in radon gas. Radon deep in the strata can also diffuse into the atmosphere through geological fault zones and groundwater. Radon diffused in the air decays into radon daughters, which are extremely fine, invisible, radioactive metal particles that can be inhaled into the lungs with the air. Some of the "radon daughters" that enter the lungs adhere to the surface mucosa of the bronchus, and some invade the body fluids and enter the lung cell tissue. They continue to "decay" in the lung cells and constantly destroy the tissue, which can cause lung cancer in severe cases.

[0003] The existing radon removal technologies can be divided into: cutting off and reducing the source of radon, ventilation dilution, indoor pressurization, filtration adsorption and electrostatic radon removal. Cutting off and reducing the source of radon requires site selection and material selection, which is not suitable for later renovation and air quality improvement; ventilation dilution is suitable for the above-ground part of the building, but the underground part can only rely on the ventilation system, which inevitably has dead corners, and the fresh air volume is large, which is not conducive to reducing the energy consumption of the building; indoor pressurization is suitable for radon removal in independent rooms, but not suitable for radon removal in suites and corridors; filtration adsorption radon removal mainly uses high-efficiency fiber filters and activated carbon adsorption methods, but this method requires frequent replacement of consumables, and pressurization and dehumidification are required to improve efficiency, and the need for settings increases the cost of use. Radon and radon daughter radiation are enriched inside the filter, which is easy to leak and affect safety; electrostatic radon removal uses the characteristics of radon daughters as metal particles to charge radon daughter particles in a high-voltage electric field, thereby generating polarity and being adsorbed on a polar dust collecting plate, but when the electric field is small or the voltage is low, the radon removal effect is not ideal. Therefore, the above radon removal technologies all have certain defects when used alone, are not suitable for the high demand for radon removal, and cannot be adaptively changed according to the air purification effect. When using composite radon removal technology, due to the large number of overall devices, it is easy for filter components to be installed incorrectly or missing, etc. In this case, the radon removal effect cannot be achieved well, affecting the overall environment.

The guide assembly 6 is also installed in the cabinet 1 and is located above the volute fan 5. The guide assembly 6 includes a plurality of corresponding guide plates 61 and a rotating shaft 62. The rotating shaft 62 is arranged along the length direction of the cabinet 1 and a plurality of them are arranged in an array along the width direction of the cabinet 1. The guide plate 61 is sleeved on the rotating shaft 62 and is arranged along the length direction of the cabinet 1. A locking member 7 is also connected to the guide assembly 6.

The locking member 7 includes a locking block 71 arranged below the guide plate 61 and a tightening block 72 abutting against the two ends of the rotating shaft 62. When in use, the purifier as a whole has a higher radon removal efficiency at low wind speed. The left and right sides of the cabinet 1 can both intake and filter air, effectively increasing the air intake surface area, thereby greatly reducing the surface wind speed of the air intake surface; the filter door 2 and the cabinet 1, the filter 4 and the cabinet 1 are firmly matched as a whole, and lead plates are provided for filtering protection, which effectively isolates the rays enriched inside and reduces radiation hazards; double locking parts 7 and unlocking parts 8 are provided to ensure that air is discharged only after the filter 4 is installed, ensuring the normal operation of the equipment.

[0042] like Figure 1 and Figure 2As shown, the filter door 2 includes a first air inlet plate 21, a second air inlet plate 22 and a door isolation plate 23.

The first air inlet plate 21 and the second air inlet plate 22 are arranged vertically parallel and corresponding to each other. After the first air inlet plate 21 and the second air inlet plate 22 are clamped and installed with the door isolation plate 23, the first air inlet plate 21 and the second air inlet plate 22 are welded and fixed around. Strip air inlet holes 24 are opened on the first air inlet plate 21 and the second air inlet plate 22. The air inlet holes 24 on the first air inlet plate 21 and the air inlet holes 24 on the second air inlet plate 22 are staggered, and ventilation holes 25 are opened on the door isolation plate 23. The filter door 2 is connected and fixed to the cabinet 1 by screws or mechanism compression, which ensures the sealing of the filter door 2 and the outer frame of the cabinet 1 and the filter door 2 can be pressed on the surface of the filter 4 to ensure the primary filtering efficiency. The filter door 2 adopts a multi-layer plate and a staggered hole structure to block the internal α, β and γ rays while ensuring air intake. The first air intake plate 21 and the second air intake plate 22 are staggered long holes, and the middle layer-door isolation plate 23 is a punched lead plate. The holes of the three layers of plates are staggered and stacked. While ensuring air intake, α, β and γ rays are blocked and absorbed, effectively reducing radiation hazards and avoiding leakage.

[0043] The first air inlet plate 21 and the second air inlet plate 22 are both provided with a receiving groove 211 for receiving the door isolation plate 23 extending toward the side close to each other. A mounting plate 221 is extended from the outer periphery of the second air inlet plate 22 away from the cabinet 1. Bolts (not shown in the figure) are passed through the mounting plate 221 to be fixed to the side of the cabinet 1. A positioning card 15 is extended near the top of the side of the cabinet 1. A positioning hole 2211 is provided on the mounting plate 221 corresponding to the positioning card 15. A receiving card 16 is extended from the bottom of the side of the cabinet 1.

The outer protective layer 427 is arranged on the side close to the filter door 2. A pull-out ring 411 is also embedded on the top of the outer frame 41 close to the filter door 2. The outer frame 41 of the filter 4 adopts a metal frame and is encapsulated with the filter element 42 by two-component glue to ensure the overall sealing of the filter 4; when the filter 4 is filtering the air intake, the air first passes through the pre-filter layer 426 to block large particles of dust, protecting the subsequent outer adsorption layer 425 and increasing its service life.
