Description

Technical Field

[0001] The invention relates to an air purification device, in particular to an air purification life support system for underground space which can reduce radon, adsorb carbon dioxide and provide oxygen. Background Art

[0002] Radon is a colorless, odorless, radioactive harmful gas. When the human body inhales air, the air enters the human lungs, and the radon in the air decays to produce alpha particles. The alpha particles constantly hit the surface of the respiratory tract, causing damage to lung cells, such as breaking chromosomes in 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 sites (such as military, pits, tunnels, accumulation and excavation projects, command and communication projects, medical rescue projects, air defense professional team projects, personnel shelter projects, etc.), air purification equipment is usually installed to reduce radon gas. At the same time, the air purification equipment can also adsorb carbon dioxide to reduce the concentration of carbon dioxide. However, there is a problem of insufficient oxygen in special underground activity venues. Traditional air purification equipment only has the functions of carbon dioxide adsorption and radon gas reduction, but does not have the function of oxygen supplementation.

The positioning seat 73 is used to place an oxygen candle 100, which is a consumable. The components inside the oxygen candle 100 are sodium chlorate (NaClO3) and metal powder. After the oxygen candle 100 is ignited, the metal powder provides heat when burning, and the 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 is completed, 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 body 10.

[0033] Each group of the positioning components 71 includes a guide tube 712, a guide bar 713 passing through the guide tube 712, a limiting column 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.

A contact is arranged on the oxygen candle 100. When the oxygen candle 100 passes through the through hole 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.

When the positioning seat 73 is completely inserted into the rear cavity 182, the first connector 80 and the second connector 90 are installed in coordination. Conversely, 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. In addition, the second connector 90 is connected to an external system controller. When the first connector 80 and the second connector 90 are installed in coordination, the system controller can control different ignition heads 736 to work separately.

[0036] The frame body 10 also includes two cross beams 111, which are arranged on both sides of the rear cavity 182 near the adjustment hole 110.

When the handle 742 is turned, the limit plate 746 and the first auxiliary plate 743 rotate in the same position, so that the limit plate 746 extends above the cross beam 111 and is stuck on the cross beam 111 or withdraws from the cross beam 111. The ball 745 effectively reduces the friction during rotation.

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

[0038] The handles 742 are turned one by one to make the limit plate 746 withdraw from above the cross beam 111.

After removing the old oxygen candle 100, the new oxygen candle 100 is placed 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, the base 72 is pushed upward until the limit column 714 installed on the guide bar 713 is stuck in the top position of the guide hole 7121, and the positioning seat 73 is completely stuck in the inner cavity. The handle 742 is turned in the opposite direction, and the limit plate 746 extends above the beam 111 and abuts against the stop column 112 on the beam 111 in the horizontal direction. The limit plate 746 is stuck on the 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 an ignition head 736. In the next use, the system controller ignites another unused oxygen candle 100 through another ignition head 736 until the oxygen candle 100 is consumed. The system controller reminds the user through sound, light or other means.

[0039] When installing the present invention, in order to make full use of the space, the wall-mounted installation is usually adopted. The positioning seat 73 adopts a vertically adjustable sunken design to reduce the height of the oxygen candle 100 for taking and placing, and the oxygen candle 100 can be taken and placed from different side positions, which effectively improves the convenience of taking and placing the oxygen candle 100, and facilitates the cleaning and maintenance of the positioning seat 73. In addition, the present invention is also provided with a second sealing door 17, which is set at one side of the oxygen supplement device 70, and the second sealing door 17 is installed on the main support frame 11 through a hinge 15. When the air purification life support system for reducing radon and adsorbing carbon dioxide to provide oxygen in the underground space adopts a floor-standing installation method, the candle can be replaced by opening the second sealing door 17.

In addition, the positioning seat 73 of the oxygen supplement device 70 adopts a sinking design with adjustable vertical position, which effectively improves the convenience of taking and placing the oxygen candle 100, and is convenient for cleaning and repairing the positioning seat 73.
