DETAILED DESCRIPTION

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: Multi-stage organic waste gas adsorption recovery device, see Figures 1 to 5, comprising a dry filter box 1, a purification box 2 and a blower 4, one end of the dry filter box 1 is connected to an air inlet pipe 11, the number of the purification boxes 2 is three, the air inlet pipe 11 and the three purification boxes 2 are connected to a first conduit 12, the inner cavity of the three purification boxes 2 are provided with an activated carbon filter disc 24, the tops of the three purification boxes 2 are connected to a second conduit 21, and the three second conduits 21 are connected to an exhaust pipe 22; the three first conduits 12 are each installed with a first electromagnetic valve 13, and the three second conduits 21 are each installed with a second The electromagnetic valve 23, the air outlet end of the blower 4 is connected to the air outlet pipe 41, the air outlet pipe 41 and the three purification boxes 2 are connected with a third conduit 42, and the three third conduits 42 are each equipped with a third electromagnetic valve 43. The center of the activated carbon filter disc 24 is rotated through a drive shaft 7, and the top of the drive shaft 7 is equipped with a drive blade 71. The third conduit 42 corresponds to the drive blade 71. The bottom of the drive shaft 7 is equipped with a cleaning plate 72, and the cleaning plate 72 is equipped with a cleaning brush 73 at one end close to the activated carbon filter disc 24. When working, , the organic waste gas is sucked in through the dry filter box 1 for dust filtration, and then the organic waste gas with dust removed is introduced into the purification box 2 through the air inlet pipe 11, and is adsorbed and filtered through the activated carbon filter disc 24, and then discharged through the exhaust pipe 22, so that the organic waste gas can be adsorbed and filtered at multiple levels, further improving the effect of organic waste gas filtration. When the activated carbon filter disc 24 is blocked and affects the filtration of organic waste gas, the third electromagnetic valve 43 on the corresponding purification box 2 is switched, and the first electromagnetic valve 13 on the corresponding purification box 2 is closed at the same time, and then the blower 4 is started to cooperate with the air outlet pipe 41 and the third conduit 42 allow air to pass into the purification box 2, thereby enabling the activated carbon filter disc 24 in the corresponding purification box 2 to be backwashed, and at the same time, the air introduced drives the fan blade 71 to rotate, thereby driving the drive shaft 7 to drive the cleaning plate 72 to rotate, and then cooperates with the cleaning brush 73 to clean the activated carbon filter disc 24, thereby improving the cleaning effect of the activated carbon filter disc 24, and does not affect the normal use of the other two purification boxes 2, and therefore, when cleaning the activated carbon filter disc 24, there is no need to stop the machine for manual cleaning by personnel, thereby improving the efficiency of adsorption and recovery of organic waste gas.

[0022] For details, see Figure 1 and Figure 2The bottoms of the three purification boxes 2 are all connected with a fourth conduit 61, and a fifth conduit 6 is connected between the three fourth conduits 61. One end of the fifth conduit 6 is connected with the catalytic burner 5. The three fourth conduits 61 are all installed with a fourth electromagnetic valve 62. When the activated carbon filter disc 24 in the purification box 2 is cleaned, the corresponding fourth electromagnetic valve 62 is opened, so that the cleaned impurities can be placed in the catalytic burner 5 through the fifth conduit 6. The catalyst is used to achieve complete oxidation of organic matter at low temperature (200-400°C) to generate CO2 and H2O, thereby preventing the cleaned impurities from polluting the air.

The first induced draft fan 15 facilitates the rapid introduction of organic waste gas into the dry filter box 1 for filtration through the dry filter cloth 14.

[0024] It is worth noting that, see Figure 1 One end of the second conduit 21 is connected to the induced draft box 3, a sixth conduit 51 is connected between the catalytic burner 5 and the induced draft box 3, and the air outlet end of the induced draft box 3 is connected to the chimney 31, through which the adsorbed and filtered gas is discharged.

[0025] It is worth noting that see Figure 5 A bearing 74 is installed at the connection between the drive shaft 7 and the activated carbon filter disc 24. The outer ring of the bearing 74 is connected to the activated carbon filter disc 24, and the inner ring of the bearing 74 is connected to the drive shaft 7. The bearing 74 reduces the friction between the drive shaft 7 and the activated carbon filter disc 24, which is conducive to blowing air in and cooperating with the driving fan blades 71 to drive the cleaning plate 72 to rotate to clean the activated carbon filter disc 24.
