Figure 4 An exploded view of an immobilization column in an embodiment, Figure 5 Schematic diagram of the enhanced degradation device in the embodiment.

[0032] The air formaldehyde treatment device of this embodiment is an air formaldehyde treatment device, which includes: a spray device 1 and a fixation column 2.

[0033] like Figure 1 As shown, a spray chamber 11 and a solution chamber 12 are provided inside the spray device 1 from top to bottom. The solution chamber 12 and the spray chamber 11 are used to contain spray liquid. The bottom of the spray chamber 11 is used to input air to be treated. A spray mechanism 13 is provided on the top for spraying spray liquid on the air to be treated and outputting the air after spraying.

[0034] like Figure 3 As shown, the immobilization column 2 includes a shell 21, a formaldehyde degradation device 22 and a filtering device 23. A partition 210 is provided in the shell 21, and a first chamber 201 and a second chamber 202 are formed by dividing the shell 210. The first chamber 201 is connected to the solution chamber 12 through a pipeline. The formaldehyde degradation device 22 includes a shell 221 and a formaldehyde degradation agent 222 arranged in the shell 221. The shell 221 is detachably connected to the partition 210, and an inlet 203 and an outlet 204 are respectively provided at both ends. The inlet 203 is connected to the first chamber 201, and the outlet 204 is connected to the second chamber 202. The filtering device 23 is arranged in the second chamber 202, and is detachably connected to the shell 21 to form a clean water chamber 205. The clean water chamber 205 is connected to the spray mechanism 13 through a pipeline.

[0035] The air formaldehyde treatment device of the above technical solution adopts spraying technology, and the spray liquid passing through the immobilized column 2 is evenly sprayed onto the flow path of the air to be treated through the spray mechanism 13, effectively capturing and dissolving the formaldehyde in the air, and the spray liquid is then collected into the solution chamber 12 and enters the first chamber 201 of the immobilized column 2, wherein the built-in formaldehyde degradation device 22 uses the formaldehyde degradation agent 222 to efficiently degrade the formaldehyde in the spray liquid, significantly reducing the formaldehyde content in the spray liquid; further, the spray liquid enters the second chamber 202, and is secondary treated by the filter device 23 to ensure the cleanliness of the spray liquid and the sustainability of recycling. The treated spray liquid is again transported to the spray mechanism 13 to form a closed-loop circulation, thereby realizing continuous and efficient treatment of formaldehyde in the air, and at the same time, extending the replacement cycle of the spray liquid. Last but not least, both the formaldehyde degradation device 22 and the filter device 23 can be disassembled and replaced, which has the advantage of reducing the cost of use.

[0036] In one embodiment of the housing 21 of the immobilization column 2, see Figure 2 and Figure 3As shown, the housing 21 includes a main body 211, a bottom cover 212 and a top cover 213. A partition 210 is provided at the bottom of the main body 211. The bottom cover 212 is detachably connected to the bottom of the main body 211 and forms a first chamber 201 between the bottom cover 212 and the partition 210.

[0039] Exemplarily, the housing 221 is connected to the inner side of the mounting hole 206 by threads or by tight connection, thereby achieving a detachable and replaceable function.

[0040] In one embodiment of the detachable connection between the filter device 23 and the housing 21, see Figure 3 and Figure 4 As shown, the filter device 23 includes a filter cartridge 230, the top of which is provided with an opening, and the edge of the opening is provided with a flange 231, and the flange 231 is clamped between the top cover 213 and the main body 211 to fix the filter cartridge 230 relative to the outer shell 21, and does not require traditional screws or snap-on structures for fixing, has a simple structure, and is easy to install; a clean water chamber 205 is formed between the inner side of the filter cartridge 230 and the top cover 213, and the top cover 213 is connected to the spray mechanism 13 through a pipeline.

[0041] Exemplarily, the filter cartridge 230 is an existing filter element such as an activated carbon filter cartridge 230 or a PP cotton filter cartridge 230 , and the filtering effect is achieved in the process that the spray liquid enters the inner side from the outer side of the filter cartridge 230 .

[0042] For example, see Figure 3 and Figure 4 As shown, the flange 231 is annular, and a waterproof sealing ring is provided at the joint between the flange 231, the top cover 213 and the main body 211.

[0043] In one embodiment of the top of the spray chamber 11 outputting the treated air, see Figure 1 As shown, the air formaldehyde treatment device further includes an exhaust gas bag 3 , which is connected to the spray chamber 11 through a pipeline and is used to receive the air output by the spray chamber 11 .

[0044] In one embodiment of the bottom of the spray chamber 11, the air to be treated is input. Figure 1As shown, the air formaldehyde treatment device further includes an air distribution bag 4 , which is connected to the spray chamber 11 through a pipeline and is used to transport the air to be treated into the spray chamber 11 .

[0046] For example, see Figure 1 As shown, the exhaust gas airbag 3 and the air distribution airbag 4 are each connected to a circulation pump 6 through a pipeline to achieve the circulation of the internal air.

[0047] To improve the delivery efficiency of the spray liquid, refer to Figure 1 As shown, the air formaldehyde treatment device also includes a micro water pump 5, which is used to drive the spray liquid in the solution chamber 12 into the immobilized column 2, and then enter the spray mechanism 13 from the immobilized column 2, so that the spray liquid circulates between the immobilized column 2 and the spray device 1.

[0048] In order to ensure that the air formaldehyde treatment device can work normally when the immobilized column 2 is repaired and the internal parts are replaced, illustratively, two immobilized columns 2 are provided and connected in parallel with the spray device 1. Independent valves are provided on the pipes connecting the two immobilized columns 2 and the spray device 1. When one immobilized column 2 stops working, its valve can be closed, and the valve of the other immobilized column 2 is opened to take over the treatment of the spray liquid.

[0049] Exemplarily, the spray mechanism 13 is an existing spray head or a spray pipe.

[0050] For example, see Figure 5 As shown, the shell 221 of the formaldehyde degradation device 22 has an openable end cover, which is convenient for placing the formaldehyde degradation agent 222 into the shell 221. At the same time, filters are provided at the inlet 203 and the outlet 204 at both ends, so that the spray liquid can enter 2 and contact with the formaldehyde degradation agent 22 and then flow out.
