Description

Technical Field

[0001] The present invention relates to an air purification device, in particular to an air purification life support system for reducing radon, adsorbing carbon dioxide and supplying oxygen in an underground space. Background Art

[0002] Radon is a colorless, odorless and radioactive harmful gas. When a person inhales air, the air enters the lungs of the human body. The radon in the air decays to produce alpha particles, and the alpha particles continuously hit the surface of the respiratory tract, causing damage to lung cells, such as breaking the chromosomes in the cells, causing radiation damage to the human respiratory system, and can induce lung cancer, leukemia and respiratory diseases. Building materials are the main source of indoor radon, such as cement, brick sand, granite and gypsum, especially natural stones containing radioactive elements, which are most likely to release radon. Therefore, for special underground activity places (such as military, tunnels, dugouts, piled-up projects and cut-and-cover projects, command and communication projects, medical rescue projects, air defense professional team projects, personnel shelter projects, etc.), air purification devices are usually installed to reduce radon. At the same time, the air purification device can also adsorb carbon dioxide and reduce the carbon dioxide concentration. However, in special underground activity places, there is a problem of insufficient oxygen. Traditional air purification devices only have the functions of carbon dioxide adsorption and radon reduction, but do not have the function of oxygen supply. Therefore, the functions are relatively single and cannot meet the user's needs. Summary of the Invention

In this embodiment, the secondary activated carbon adsorption device 40 adopts a coconut shell modified activated carbon cotton filter. The secondary activated carbon adsorption device 40 is used to adsorb radon and its factors in the air. The carbon dioxide adsorption device 50 adsorbs carbon dioxide in the air to reduce the concentration of carbon dioxide in the air.

[0032] The oxygen supply device 70 includes a plurality of adjustment components 71, a base 72 installed on the adjustment components 71, a positioning seat 73 installed on the base 72, and a plurality of clamping members 74. After loosening the clamping members 74, the base 72 installed on the adjustment components 71 can be adjusted in the vertical direction, so that the positioning seat 73 installed on the base 72 extends into the rear cavity 182 of the frame main body 10 from the adjustment hole 110 or extends out from the rear cavity 182 and the adjustment hole 110. The positioning seat 73 is used to place the oxygen candle 100. The oxygen candle 100 is a consumable. The components inside the oxygen candle 100 are sodium chlorate (NaClO3) and metal powder. After the oxygen candle 100 is lit, the metal powder provides heat during combustion, and sodium chlorate undergoes an oxidation-reduction reaction when heated to generate oxygen. When the oxygen candle 100 needs to be replaced, the positioning seat 73 is moved out of the rear cavity 182 in the vertical direction. After installation, the positioning seat 73 is moved upward, and the positioning seat 73 and the oxygen candle 100 placed on the positioning seat 73 extend into the rear cavity 182 of the frame main body 10.

[0033] Each of the position adjustment components 71 includes a guide tube 712, a guide bar 713 disposed on the guide tube 712, a limit post 714 passing through the guide tube 712 and connected to the guide bar 713, and a connecting plate 711 connected to one end of the guide tube 712. The connecting plate 711 is installed on the frame body 10, and the guide tube 712 is provided with a hollow structure. The guide tube 712 is provided with a guide hole 7121, and the guide hole 7121 on the guide tube 712 penetrates from the outside to the inside. The guide hole 7121 is an elongated hole, and the extending direction of the orifice of the guide hole 7121 is consistent with the axial direction of the guide tube 712. During installation, the limit post 714 passes through the guide hole 7121 and is cooperatively installed with the guide bar 713 by means of threads.

[0035] Each of the ignition heads 736 includes a first terminal 7361 and a second terminal 7362. Among them, the first terminal 7361 is disposed at the center position of the card seat 734, and the second terminal 7362 is disposed at a position on one side of the first terminal 7361. The oxygen replenishing device 70 further includes a first connector 80 and a plurality of cables. The first connector 80 is installed at a position near the edge of the base 72. The first terminals 7361 and the second terminals 7362 on different ignition heads 736 are respectively connected to the first connector 80 through the cables. A contact is provided on the oxygen candle 100. When the oxygen candle 100 passes through the perforation 7321 and is placed on the sleeve 735, the first terminal 7361 contacts the contact of the oxygen candle 100, and the second terminal 7362 contacts the outer surface of the oxygen candle 100. After being powered on, the ignition head 736 ignites the oxygen candle 100. The present invention further includes a second connector 90. The second connector 90 is installed on the main support frame 11, and the second connector 90 extends into the moving path of the first connector 80 in the vertical direction. When the positioning seat 73 is completely snapped into the rear cavity 182, the first connector 80 and the second connector 90 are cooperatively installed. On the contrary, when the positioning seat 73 is moved out of the rear cavity 182 in the vertical direction, the first connector 80 is separated from the second connector 90. Moreover, the second connector 90 is connected to an external system controller. After the first connector 80 and the second connector 90 are cooperatively installed, the system controller can independently control the operation of different ignition heads 736.

[0036] The frame body 10 further includes two cross beams 111. The two cross beams 111 are arranged on both sides of the rear cavity 182 near the position of the adjustment hole 110. The two cross beams 111 are installed on the main support frame 11. Position-limiting columns 112 are provided on the cross beams 111. The positioning member 74 includes a handle 742, a positioning sleeve 741, a first auxiliary plate 743, a second auxiliary plate 744, a limiting plate 746, a plurality of balls 745 and a plurality of locking screws (not shown in the figure). The handle 742 includes a main body section 7421. Rotating grooves (not shown in the figure) are provided on both the first auxiliary plate 743 and the second auxiliary plate 744. During assembly, the positioning sleeve 741 is installed on the housing 12 at the bottom of the frame body 10 through the locking screws. The main body section 7421 of the handle 742 passes through the positioning sleeve 741, the housing 12, the second auxiliary plate 744, and the first auxiliary plate 743 from the bottom. The limiting plate 746 is installed at the end position of the main body section 7421 and on the first auxiliary plate 743 through the locking screws. The balls 745 are clamped between the rotating groove of the first auxiliary plate 743 and the rotating groove of the second auxiliary plate 744. The second auxiliary plate 744, the first auxiliary plate 743 and the balls 745 support the limiting plate 746 in the vertical direction. When the handle 742 is rotated, the limiting plate 746 and the first auxiliary plate 743 rotate in the same position, so that the limiting plate 746 extends above the cross beam 111 and is clamped on the cross beam 111 or exits from above the cross beam 111. The balls 745 effectively reduce the friction during rotation.

[0037] The process of placing the oxygen candle 100 will be further described below:

[0038] Rotate the handle 742 one by one to withdraw the limit plate 746 from above the cross beam 111. Under the action of gravity, the base 72, positioning seat 73, clamping member 74, position adjustment assembly 71, first connector 80 and guide bar 713, which are connected as a whole, shift downward. The guide tube 712 guides the guide bar 713. The first connector 80 separates from the second connector 90. The positioning seat 73 extends out of the rear cavity 182 in the vertical direction until the limit post 714 installed on the guide bar 713 is stuck at the bottommost position of the guide hole 7121. After removing the old oxygen candle 100, place the new oxygen candle 100 on the sleeve 735 of the positioning seat 73. The first terminal 7361 contacts the contact of the oxygen candle 100, and the second terminal 7362 contacts the outer surface of the oxygen candle 100. After the installation of the oxygen candle 100 is completed, push the base 72 upward until the limit post 714 installed on the guide bar 713 is stuck at the topmost position of the guide hole 7121, and the positioning seat 73 is completely snapped into the inner cavity. Rotate the handle 742 in the reverse direction, and the limit plate 746 extends above the cross beam 111 and abuts against the stop post 112 on the cross beam 111 in the horizontal direction. The limit plate 746 is clamped on the cross beam 111 in the vertical direction. During operation, the system controller detects the external air concentration according to the oxygen concentration detection sensor. When the air concentration is lower than the set value, the system controller ignites the oxygen candle 100 in contact with it through a lighter head 736. In the next use, the system controller ignites another unused oxygen candle 100 through another lighter head 736 until all the oxygen candles 100 are consumed, and the system controller reminds the user through sound, light or other means.

[0039] During the installation of the present invention, in order to make full use of space, it is usually installed in a wall-mounted manner. The positioning seat 73 adopts a sunken design with adjustable vertical position, which reduces the height for taking and placing the oxygen candle 100, and the oxygen candle 100 can be taken and placed from different side positions, effectively improving the convenience of taking and placing the oxygen candle 100, and at the same time facilitating the cleaning and maintenance of the positioning seat 73. In addition, the present invention is also provided with a second sealing door 17, and the second sealing door 17 is arranged at one side of the oxygen replenishing device 70. The second sealing door 17 is installed on the main support frame 11 through a hinge 15. When the underground space radon reduction, carbon dioxide adsorption and oxygen supply air purification life support system adopts a floor-mounted installation method, the candle can be replaced by opening the second sealing door 17.

[0040] The beneficial effects of the air purification life support system for reducing radon, adsorbing carbon dioxide, and supplying oxygen in underground spaces of the present invention are as follows: Based on the primary activated carbon adsorption device 20, high-voltage plasma purification device 30, secondary activated carbon adsorption device 40, carbon dioxide adsorption device 50, and centrifugal fan 60, an oxygen supply device 70 is further provided. The oxygen supply device 70 is used to place oxygen candles 100, so that the air purification life support system for reducing radon, adsorbing carbon dioxide, and supplying oxygen in underground spaces has the functions of radon reduction, carbon dioxide adsorption, and oxygen supply, effectively improving the practicality of the air purification life support system for reducing radon, adsorbing carbon dioxide, and supplying oxygen in underground spaces. In addition, the positioning seat 73 of the oxygen supply device 70 adopts a sunken design with adjustable vertical position, effectively improving the convenience of taking and placing the oxygen candles 100, and at the same time facilitating the cleaning and maintenance of the positioning seat 73.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
