Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0018] Example
[0019] See also Figure 1-3The utility model provides a technical solution: a gas filtering and silencing structure of a pressure swing adsorption device, including an adsorption box 1, the adsorption box 1 includes a lower half box 11 and an upper half box 12, the lower half box 11 and the upper half box 12 are spliced from bottom to top, an air inlet pipe 2 is provided on one side of the lower half box 11, specifically, the air inlet pipe 2 is fixedly connected to the lower half box 11 and communicated with each other, an air outlet pipe 3 is provided on the top surface of the upper half box 12, specifically, the air outlet pipe 3 is fixedly connected to the upper half box 12 and communicated with each other, the upper half box 1 2 is provided with a plurality of activated carbon adsorption layers 5 at internal intervals. Specifically, the activated carbon adsorption layer 5 is fixed to the inner wall of the upper half box 12 by screws, and the activated carbon adsorption layer 5 is inclined. Specifically, the activated carbon adsorption layer 5 is inclined, which can increase the contact area with the gas in disguised form and better adsorb and filter. The inner walls of the air inlet pipe 2 and the air outlet pipe 3 are provided with a plurality of silencer rods 4. Specifically, the silencer rods 4 are fixedly connected to the inner wall of the air inlet pipe 2 or the air outlet pipe 3, and the silencer rods 4 are arranged in a porous structure.
[0020] In this embodiment, when working, the gas enters the adsorption box 1 through the air inlet pipe 2, and the porous structure of the silencer rod 4 on the inner wall of the air inlet pipe 2 absorbs the sound to a certain extent. The gas entering the adsorption box 1 slowly rises to the upper box 12 through the lower half box 11, and is adsorbed and filtered through the activated carbon adsorption layer 5. The filtered gas enters the outlet pipe 3, and the porous structure of the silencer rod 4 on the inner wall of the outlet pipe 3 absorbs the sound to a certain extent again. In this scheme, the adsorption box 1 is spliced by the lower half box 11 and the upper half box 12, and is detachable, which is convenient for replacing the activated carbon adsorption layer 5 or adjusting the number of activated carbon adsorption layers 5 in the upper half box 12.
[0021] Furthermore, a protrusion 7 is provided on the bottom surface of the frame of the upper half box 12. Specifically, the protrusion 7 and the upper half box 12 are an integral structure. A slot 8 is provided on the top surface of the frame of the lower half box 11. The protrusion 7 is cooperatively connected with the slot 8. Specifically, the protrusion 7 can be inserted into the slot 8 and is slidably connected with the slot 8.
[0022] In this embodiment, the upper half box 12 can be limited by the cooperation between the protrusion 7 and the slot 8 to avoid tilting and affecting the air tightness.
[0023] Furthermore, the outer surface of the protrusion 7 is covered with a sealing gasket 9 .
[0024] In this embodiment, the sealing gasket 9 is provided to better ensure the sealing performance of the connection between the upper half box 12 and the lower half box 11 .
[0025] Furthermore, the lower half box 11 and the upper half box 12 are connected by buckles.
[0026] In this embodiment, the lower half box 11 and the upper half box 12 can be quickly fixed or separated by buckles.
[0027] Furthermore, a plurality of transverse baffles 6 are provided at intervals on the bottom surface of the activated carbon adsorption layer 5 . Specifically, the transverse baffles 6 are fixedly connected to the activated carbon adsorption layer 5 .
[0028] In this embodiment, a transverse baffle 6 is provided to prevent the gas from moving vertically directly. After the gas hits the transverse baffle 6, it is forced to change its moving trajectory, thereby slowing down the moving speed of the gas and improving the filtering effect.
[0029] Furthermore, the air outlet pipe 3 and the air inlet pipe 2 are arranged in a staggered manner.
[0030] In this embodiment, the air outlet pipe 3 and the air inlet pipe 2 are staggered, and the gas movement trajectory is not a straight line, so that the movement rate of the gas can be slowed down and the filtering effect can be improved.
