Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a VOCs activated carbon box. Background Art

[0002] VOCs activated carbon box, also known as activated carbon adsorption box or activated carbon tower, is a high-efficiency air filtration equipment specially used to treat volatile organic compounds.

[0003] The existing activated carbon box has a simple structure and a single built-in filtering flow channel, but a single filtration cannot effectively ensure the air purification quality. The filtration quality is easily reduced due to the saturation of the activated carbon, so the use effect is poor. In addition, the existing activated carbon box needs to replace the internal activated carbon regularly, but the internal activated carbon is not convenient to replace and maintain, and the operation is difficult. Utility Model Content

[0004] The purpose of the utility model is to provide a VOCs activated carbon box with dual-channel secondary filtration, ensuring processing quality and convenient disassembly and replacement, reducing the difficulty of operation, and solving the problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a VOCs activated carbon box, comprising a box body and a carbon box, wherein an air intake pipe and an exhaust pipe are respectively installed at both ends of the box body, and docking grooves are provided on both sides of the inner end of the air intake pipe and the inner end of the exhaust pipe; a slidable pull-out box is provided on the front and back sides of the box body, an assembly groove is provided on the top of the pull-out box, an arc-shaped groove is provided on the inside of the pull-out box, an air escape groove is provided inside the arc-shaped groove, and the air escape groove is connected to the assembly groove; the carbon box is slidably inserted into the assembly groove, and a groove is provided on the side of the carbon box close to the air intake pipe or the side close to the exhaust pipe, and a flow hole is provided in the groove.

[0006] When using a VOCs activated carbon box in the present technical solution, the air supply pipe is connected to the outer end of the air inlet pipe, the gas is introduced into the air inlet pipe, and is guided to the corresponding pull-out box through the docking grooves on both sides. The gas is introduced from the flow hole into the carbon box through the air groove of the pull-out box, and the organic compounds in the gas are adsorbed by the activated carbon inside the carbon box. The gas is then discharged from the mesh plate on the lower side of the carbon box. The gas enters one side of the box body and is introduced into the other side of the box body through the gap under the partition. The gas on this side then enters the carbon box through the bottom mesh plate, and is again subjected to secondary adsorption and filtration by the activated carbon in the carbon box. After the secondary filtration, the gas enters the exhaust pipe through the flow hole and the docking groove, and is discharged outward through the exhaust pipe. During maintenance, the bolts used to fix the pull-out box are removed, and then the pull-out box is slid outward, and the carbon box is extracted upward to replace it with a new one.

[0007] Preferably, the lower surface of the box is fixed with foot pads, and there are four foot pads in total, which are distributed in an array, and the lower surface of the foot pads is also fixed with anti-skid pads. The foot pads are used to support the placement of the box, and the anti-skid pads increase friction and ensure support stability.

[0008] Preferably, a partition is fixed inside the box, and a gap is left between the lower side of the partition and the bottom of the box, and the air intake pipe and the exhaust pipe are respectively located on both sides of the partition. The partition is used to position the inner ends of the air intake pipe and the exhaust pipe and to separate the internal space of the box.

[0009] Preferably, guide rails are provided between the partition and the inner wall of the box, and the pull-out box is slidably mounted between two guide rails corresponding to the partition and the box. The sliding installation of the pull-out box is achieved through the guide rails.

[0010] Preferably, the arc groove inside the pull-out box fits with the outer wall of the air inlet pipe or the outer wall of the exhaust pipe, and the docking groove is connected to the air outlet groove. The arc groove improves the connection and fit between the pull-out box and the air inlet pipe and the exhaust pipe.

[0011] Preferably, the circulation hole corresponds to the air vent, and a mesh plate is provided at the bottom opening of the carbon box to prevent the activated carbon bag inside the carbon box from leaking out while allowing air to circulate through the mesh plate.

[0012] Preferably, the bottom of the pull-out box is open, and gaskets are fixed at the four right angles of the lower end of the assembly groove, and the four gaskets respectively support the four right angles of the lower end of the carbon box. The pull-out box is positioned by the gaskets so that it is limited in the assembly groove.

[0013] Preferably, the box body is further provided with a side groove for the pull-out box to be drawn out, and the outer end of the pull-out box is located in the side groove, and the side groove wall and the pull-out box are slidably sealed. The pull-out box can be slid out through the side groove, which is convenient for maintenance.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the air supply pipe is connected to the outer end of the air intake pipe, the gas is introduced into the air intake pipe, and is guided to the corresponding pull-out box through the docking grooves on both sides, and the gas is introduced from the flow hole into the carbon box through the air groove of the pull-out box, and the organic compounds in the gas are adsorbed by the activated carbon inside the carbon box, and then the gas is discharged from the mesh plate on the lower side of the carbon box. The gas enters one side of the interior of the box and is introduced into the other side of the box through the gap under the partition, and then the gas on this side enters the carbon box through the bottom mesh plate, and is again subjected to secondary adsorption and filtration by the activated carbon in the carbon box. After the secondary filtration, the gas enters the exhaust pipe through the flow hole and the docking groove, and is discharged outward through the exhaust pipe. During maintenance, the bolts used to fix the pull-out box are removed, and then the pull-out box is slid outward, and the carbon box is extracted and pulled out upward to replace it with a new carbon box. The device is easy to operate and performs secondary filtration through the built-in channel to ensure the quality of gas purification. At the same time, the structural design for convenient disassembly and cleaning facilitates the replacement of the carbon box and reduces the difficulty of operation.
