Description

Technical Field

[0001] The invention relates to the technical field of radon daughter removal and purification, and more particularly to a radon daughter removal device. Background Art

[0002] Radon progeny mainly refers to the general term for the decay products of radon (222Rn), including proton-218, lead-214, bismuth-214 and proton-214. Radon progeny are very harmful to the human body. Long-term exposure to high-concentration radon progeny environments will increase the risk of lung cancer. In addition, radon progeny can also cause radiation damage to other organs.

[0003] The existing radon progeny removal technology mainly uses ventilation. Although ventilation is the simplest and most effective way to remove radon progeny, it requires a good ventilation system. Some air purifiers can remove radon progeny, but the effect is limited. Some later negative ion generators can reduce the concentration of radon progeny, but they cannot completely remove them. Activated carbon can adsorb radon progeny, but it needs to be replaced regularly.

[0004] Therefore, radon progeny removal technology faces certain challenges: therefore, how to develop a more effective radon progeny removal device and related methods has become one of the technical problems that urgently need to be solved in this field. Summary of the invention

[0005] In view of this, the present invention provides a radon daughter removal device for at least partially solving the technical problems in the background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] The present invention first discloses a radon daughter removal device, comprising a box body, the box body is provided with an air inlet and an air outlet, and the box body is provided with a primary filter, a high-efficiency filter, a honeycomb electric field, a flat plate electric field, an ozone decomposition network and an activated carbon filter in sequence from the air inlet to the air outlet;

[0008] A radon progeny sensor is provided on the inner side of the air inlet. The radon progeny sensor uses the Mobus TCP protocol to transmit data with the control system. When the radon progeny sensor detects that the radon progeny concentration at the air inlet is higher than the set threshold, the cellular electric field and the flat plate electric field start to operate; when the radon progeny sensor detects that the radon progeny concentration at the air inlet is lower than the set threshold, the cellular electric field and the flat plate electric field stop operating.

[0009] Preferably, the honeycomb electric field and the flat plate electric field adopt a combination of Rn electrocoagulation purification technology and Rn square array purification technology to remove radon progeny in the air.

[0010] Preferably, the primary filter comprises a non-woven filter of 20-40 mesh.

[0011] Preferably, the high-efficiency filter includes a HEPA filter of H13 specification.

[0012] Preferably, the primary filter, high efficiency filter, ozone decomposition filter and activated carbon filter are all installed in the box in a detachable manner.

[0013] Preferably, the primary filter, high efficiency filter, ozone decomposition filter and activated carbon filter are replaced every six months.

[0014] The present invention also discloses a method for removing radon progeny, comprising the following steps:

[0015] Using radon progeny sensors to detect the concentration of radon progeny;

[0016] When the concentration of radon progeny detected is higher than the set threshold, the radon progeny are removed by combining Rn electrocoagulation purification technology and Rn square array purification technology;

[0017] When the concentration of radon progeny is detected to be lower than the set threshold, the radon progeny removal operation will be automatically stopped.

[0018] Furthermore, the concentration data of radon progeny detected in the above method is transmitted using the Mobus TCP protocol.

[0019] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a radon daughter removal device, which has the following beneficial effects:

[0020] The present application can automatically remove radon progeny in the environment according to the detected radon progeny concentration, and more effectively remove radon progeny in the environment through Rn electrocoagulation purification technology and Rn square array purification technology.

[0021] The radon daughter removal device proposed in the present application can remove ozone generated by the honeycomb electric field and the flat plate electric field by using an ozone decomposition network. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0023] Figure 1 This is a schematic diagram of the overall structure of the multifunctional radon daughter removal equipment provided by the present invention. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] Embodiment 1 of the present invention discloses a radon daughter removal device, such as Figure 1 As shown, it includes a box body 100, which is provided with an air inlet and an air outlet, and the box body 100 is provided with a primary filter 1, a high-efficiency filter 2, a honeycomb electric field 3, a flat electric field 4, an ozone decomposition network 5 and an activated carbon filter 6 in sequence from the air inlet to the air outlet;

[0027] A radon progeny sensor is provided on the inner side of the air inlet of the multifunctional radon progeny removal equipment. The radon progeny sensor uses the Mobus TCP protocol to transmit data with the control system. When the radon progeny sensor detects that the radon progeny concentration at the air inlet is higher than the set threshold, the cellular electric field 3 and the flat plate electric field 4 start to run; when the radon progeny sensor detects that the radon progeny concentration at the air inlet is lower than the set threshold, the cellular electric field 3 and the flat plate electric field 4 stop running.

[0028] In the present invention, impurities in the air are first filtered through the primary filter 1 and the high-efficiency filter 2. Specifically, in a specific embodiment, the primary filter 1 can be a 20-40 mesh non-woven filter, or a filter made of polyester or nylon, which is used to absorb and filter larger particles in the air, such as dust, hair, pollen, etc. The high-efficiency filter 2 can be a H13 specification HEPA filter, which is used to absorb and filter smaller particles in the air, such as PM2.5, etc.

[0029] The air after impurities are removed by the primary filter 1 and the high-efficiency filter 2 enters the honeycomb electric field 3 and the flat plate electric field 4 in turn. The honeycomb electric field and the flat plate electric field adopt a combination of Rn electrocoagulation purification technology and Rn square array purification technology to remove radon progeny in the air.

[0030] First, the honeycomb electric field 3 removes radon progeny in the air in a centralized manner by ionization. Specifically, the honeycomb electric field 3 includes a plurality of honeycomb dust collecting electrodes and discharge electrodes arranged inside the honeycomb dust collecting electrodes, and the honeycomb dust collecting electrodes on the same column in the honeycomb electric field are interconnected. In the embodiment of the present invention, the honeycomb electric field can use the discharge electrodes to generate a high-voltage electric field to ionize the radon progeny in the air, so that they are adsorbed onto the honeycomb dust collecting electrodes.

[0031] The remaining radon daughters after being removed by the honeycomb electric field are then further precipitated and adsorbed by the flat electric field 4. The flat electric field can generate an electrostatic field, and the charged radon atoms will precipitate under the action of the electrostatic field and settle on the dust collecting plate of the flat electric field.

[0032] Since some ozone is incidentally generated under the high voltage electric field in the honeycomb electric field 3 and the flat electric field 4, an ozone decomposition net 5 is additionally provided in the present invention to quickly decompose the ozone incidentally generated by the high voltage electric field. Specifically, in the embodiment of the present invention, the ozone decomposition net 5 is a double-layer mesh structure, and a catalyst for ozone decomposition is placed in the middle of the double-layer mesh structure, such as manganese dioxide (MnO2), iron oxide (Fe2O3), cobalt oxide (CoO), nickel oxide (NiO) and other metal oxide catalysts, so as to adsorb ozone molecules in the air and promote their rapid decomposition.

[0033] The main function of the ozone decomposition network is to promote the rapid decomposition of ozone. Its principle is to use catalysts to accelerate the decomposition process of ozone.

[0034] Common ozone decomposition catalysts include:

[0035] Metal oxides: Common metal oxide catalysts include manganese dioxide (MnO2), iron oxide (Fe2O3), cobalt oxide (CoO), nickel oxide (NiO), etc. These metal oxides have a large surface area and abundant active sites, which can adsorb ozone molecules and promote their decomposition, thereby effectively removing ozone from the air and ensuring environmental safety.

[0036] The multifunctional radon daughter removal device finally utilizes an activated carbon filter 6 to adsorb volatile organic compounds (VOC) in the air to be purified.

[0037] In order to facilitate quick installation and maintenance, the primary filter 1, the high-efficiency filter 2, the ozone decomposition network 5 and the activated carbon filter 6 in the present application are all installed in the box 100 in a detachable manner.

[0038] In order to ensure the quality of the equipment in removing radon progeny, in the present invention, the primary filter 1, the high-efficiency filter 2, the ozone decomposition network 5 and the activated carbon filter 6 are replaced every six months.

[0039] In order to facilitate movement, moving wheels are provided at the bottom of the box 100 to facilitate movement of the multifunctional radon removal device. Furthermore, in a specific design, the moving wheels are installed at the bottom of the box 100 in a foldable form. When the multifunctional radon removal device is moved to a specified position by the moving wheels, the moving wheels are folded toward the inside of the box by a foldable device to facilitate the stable fixation of the multifunctional radon removal device.

[0040] Example 2

[0041] Embodiment 2 discloses a method for removing radon progeny, comprising the following steps:

[0042] Using radon progeny sensors to detect the concentration of radon progeny;

[0043] When the concentration of radon progeny detected is higher than the set threshold, the radon progeny are removed by combining Rn electrocoagulation purification technology and Rn square array purification technology;

[0044] When the concentration of radon progeny is detected to be lower than the set threshold, the radon progeny removal operation will be automatically stopped.

[0045] Furthermore, the concentration data of radon progeny detected in the above method is transmitted using the Modbus TCP protocol. Specifically, the radon progeny concentration data detected by the sensor can be converted into single-precision floating-point numbers, and the converted single-precision floating-point data can be encapsulated into a Modbus TCP message and transmitted to the data processing module for threshold judgment. The data processing module receives the Modbus TCP message and parses it into concentration data.

[0046] The radon daughter removal method disclosed in Example 2 can be implemented based on the multifunctional radon daughter removal device disclosed in Example 1.

[0047] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.

For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0048] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
