At the same time, when the activated carbon is saturated with the harmful substances and organic substances in the organic waste gas, the external heater is turned on by control. When the external heater is turned on, the heating chamber is heated by the heating copper tube. When the heating copper tube heats the heating chamber, the activated carbon is heated and desorbed, so that the activated carbon releases the adsorbed organic substances. When the activated carbon releases the adsorbed organic substances, the organic substances enter the condensation tank through the connecting pipe. When the organic substances enter the condensation tank, the external refrigerator is turned on by control. When the external refrigerator is turned on, the organic substances in the condensation tank are condensed through the refrigeration copper tube. After the organic substances are condensed, the condensed organic substances can be recycled and reused through the recovery pipe, thereby achieving the purification of the organic waste gas and the recycling of the organic substances in the organic waste gas.

A limit slide bar 10 is fixedly installed in the middle of the inner bottom of the mounting circular groove 9. The outer curved surface of the upper end of the limit slide bar 10 is movably connected with a filter element 11 for filtering organic waste gas, and the outer ends of both sides of the filter element 11 are movably connected to the inner wall of the straight slide groove 8, so that the dust particles in the organic waste gas are filtered and processed by the filter element 11. A support spring 12 is fixedly installed on the inner bottom circumference of the mounting circular groove 9, and the support spring 12 is in a compressed state. The upper end of the support spring 12 is movably connected to both sides of the bottom of the filter element 11, so that the filter element 11 is elastically supported by the support spring 12;

[0027] An adsorption box 13 for placing activated carbon is fixedly installed at the bottom of the purification box 2, and a sealing plug is interference-connected at the opening of the upper end of the adsorption box 13. There are two adsorption boxes 13, which are symmetrically distributed on both sides of the bottom of the purification box 2. A guide pipe 14 is fixedly installed through the front end of the adsorption box 13, and the guide pipe 14 extends downward to the lower end of the adsorption box 13. The front inlet of the guide pipe 14 is connected with the rear end of the pretreatment box 1 through a connecting pipe. A heating chamber 15 is fixedly installed at the bottom of the purification box 2, and a heating copper tube 16 for heating the adsorption box 13 is fixedly installed on the top support of the heating chamber 15, and the side end of the heating copper tube 16 passes through the heating chamber 15 to be connected with an external heater;

[0028] A condensation tank 17 is fixedly installed on the internal support of the recovery box 3. The front end of the condensation tank 17 is connected to the upper end of the rear side of the adsorption box 13 through a connecting pipe.

[0029] Working principle: When in use, the utility model is connected with the external organic waste gas pipeline through the connecting flange. When the connecting flange is connected with the external organic waste gas pipeline, the suction fan 5 is turned on by control. When the suction fan 5 is turned on, the organic waste gas inside the external organic waste gas pipeline will be discharged into the pretreatment box 1. When the organic waste gas is discharged into the pretreatment box 1, the dust particles in the organic waste gas will be filtered through the filter element 11 to achieve the purpose of pretreatment of the organic waste gas. Through pretreatment, the effect and stability of subsequent treatment links can be improved. At the same time, when the filter element 11 needs to be cleaned and replaced, the sealing cover 7 is opened by closing the electromagnetic switch. When the sealing cover 7 is opened, the filter element 11 will move straightly upward along the outer curved surface of the limit slide bar 10 and the inner wall of the straight slide groove 8 under the push of the elastic potential energy generated by the compression deformation of the support spring 12. When the filter element 11 moves straightly upward, the upper end of the filter element 11 will move out of the replacement port 6, so that the upper end of the filter element 11 protrudes from the replacement port 6, making it easy to lift the filter element 11 out of the pretreatment box 1, thereby achieving filtering of the organic waste gas and facilitating the replacement of the filter element 11;

[0030] After the filter element 11 filters the dust particles in the organic waste gas, the filtered organic waste gas will enter the bottom of the adsorption box 13 through the guide tube 14. When the organic waste gas enters the bottom of the adsorption box 13 through the guide tube 14, the activated carbon inside the adsorption box 13 will adsorb and purify the harmful substances and organic substances in the organic waste gas, so as to achieve the effect of purifying the organic waste gas. At the same time, when the activated carbon is saturated with the harmful substances and organic substances in the organic waste gas, the external heater is turned on by control. When the external heater is turned on, the heating chamber 15 will be heated by the heating copper tube 16. When the heating copper tube 16 heats the heating chamber 15 When hot, the activated carbon will be heated to desorb, causing the activated carbon to release the adsorbed organic matter. When the activated carbon releases the adsorbed organic matter, the organic matter will enter the condensation tank 17 through the connecting pipe. When the organic matter enters the condensation tank 17, the external refrigerator is turned on by control. When the external refrigerator is turned on, the organic matter inside the condensation tank 17 will be condensed through the refrigeration copper tube 18. After the organic matter is condensed, the condensed organic matter can be recovered and reused through the recovery pipe 19, thereby achieving the purification of the organic waste gas while recycling the organic matter in the organic waste gas.
