The working principle is as follows:

firstly, an exhaust fan 105 is started through an intelligent control cabinet 115, then the exhaust fan 105 operates, then exhaust gas enters an adsorption tower 102 through an exhaust gas inlet pipe 107 under the driving of the exhaust fan 105, then the exhaust gas passes through a vertical adsorption pipe 111, a divergent opening adsorption pipe 112, a gap between activated carbon inside the adsorption tower 102, a clean gas pipe 104, the exhaust fan 105 and is discharged from a clean gas discharge pipe 106, when the exhaust gas flows in the gap between the activated carbon, the activated carbon in the exhaust gas adsorbs VOCs in the exhaust gas on the source side, the activated carbon in the exhaust gas is preferentially contacted with the exhaust gas, the activated carbon on the exhaust gas source side is preferentially saturated, the purification purpose is realized, then the intelligent control cabinet 115 is subjected to time point setting, when a time point is reached, the intelligent control cabinet 115 controls an electric cylinder 218 to shrink, then the electric cylinder 218 drives a gate breaking plate 215 to move downwards through a linkage plate 217, and then a circulation pipe 213 is opened, then the activated carbon in the drying box 209 enters the adsorption tower 102 through the circulating material pipe 213 under the action of gravity, then the intelligent control cabinet 115 controls the pushing motor 113 to operate for a period of time, then the pushing motor 113 drives the pushing auger 114 to rotate, then the pushing auger 114 pushes the activated carbon to move upwards, then the activated carbon at the top end of the vertical adsorption pipe 111 overflows from the inside and falls on the top surface of the inclined material guide plate 108, then the intelligent control cabinet 115 controls the electric gate valve 110 to open, then the activated carbon on the top surface of the inclined material guide plate 108 passes through the inclined material guide flat pipe 109 under the action of gravity to enter the regeneration tower 301 and fall inside the transfer hole 207, then the transfer hole 207 is filled with the activated carbon, then the activated carbon is accumulated in a cavity above the transfer hole 207 in the regeneration tower 301, then the intelligent control cabinet 115 closes the adsorption tower after the pushing motor 113 operates for a period of time, at this time, only a small amount of activated carbon remains in the drying box 209, then the intelligent control cabinet 115 controls the electric cylinder 218 to extend, then the electric cylinder 218 drives the gate breaking plate 215 to move upwards through the linkage plate 217, then the gate breaking plate 215 seals the circulating material pipe 213, then the intelligent control cabinet 115 controls the electric gate valve 110 to close, then the intelligent control cabinet 115 controls the W-shaped heating rod 47 to open, then the temperature of the surface of the W-shaped heating rod 47 gradually rises, the W-shaped heating rod 47 is preheated, after a period of preheating, the intelligent control cabinet 115 controls the water lifting pump 302 to operate, then the water lifting pump 302 drives water to slowly enter the conical buffer box 42 through the water lifting pipe 303, then the water flows onto the surface of the W-shaped heating rod 47 through the diversion holes 46 to form a water film, then the water film quickly absorbs heat on the W-shaped heating rod 47 and generates steam, and then liquid water which does not reach evaporation flows downwards along the surface of the W-shaped heating rod 47 and drops into the circular truncated cone-shaped container 507, then the round platform shaped container 507 overcomes the elasticity of the buffer spring 505 and moves downwards under the action of the water gravity, then the round platform shaped container 507 applies pressure to the insulation opening bars 511 through the positioning sheets 510, then the opening angle of the two insulation opening bars 511 is increased, then the two insulation opening bars 511 carry the two conductive sliding blocks 512 away from each other, then the conductive sliding blocks 512 slide on the outer surface of the resistance bar 513, then the resistance bar 513 enters the circuit, then a current is formed inside the resistance bar 513, then the intelligent control cabinet 115 receives the current signal and controls the power of the W-shaped heating bar 47 to increase, as the water inside the round platform shaped container 507 increases, the length of the access circuit of the resistance bar 513 further increases, then the intelligent control cabinet 115 increases the electric power of the W-shaped heating bar 47 according to the length of the access circuit of the resistance bar 513, the length of the access circuit of the resistance bar 513 is longer, the higher the power of the W-shaped heating rod 47 is, the more the truncated cone-shaped container 507 does not move downwards, so that evaporation balance is achieved, then the intelligent control cabinet 115 controls the operation of the blower fan 324 to drive water vapor and air to flow upwards, meanwhile, an external refrigerator injects condensate into the interior of the condensate inlet pipe 323, so that the condensate flows through the third circular water channel 317, the second straight water channel 319, the second circular water channel 316, the first straight water channel 318, the first circular water channel 315, the spiral condensation pipe 321 and the condensate discharge pipe 322 in a circulating manner, then the water vapor passes through the vapor homogenizing hole 309, the corresponding transfer hole 207 and the gap between the activated carbons, then the water vapor heats the activated carbons, then VOCs adsorbed in the activated carbons are heated and evaporated and mixed with the water vapor to form mixed gas flow, then the mixed gas flow passes through the reducing pipe 310, the steam through pipe 311 and the steam through hole 312 to flow upwards, then the mixed gas flow enters the vertical air passage 320 and is blown on the surface of the spiral condensation pipe 321 to release heat, then the water vapor and the VOCs are gradually liquefied on the inner wall of the vertical air passage 320 and the surface of the spiral condensation pipe 321, the unliquefied mixed gas passes through the vertical air passage 320, the blowing fan 324, the blowing pipe 325, the heat exchanger 326 and the circulating steam pipe 327 and flows back to the inside of the circular truncated cone-shaped guide pipe 509 to be mixed with the fresh water vapor, then the liquefied mixed liquid drops downwards along the inner wall of the vertical air passage 320 and the surface of the spiral condensation pipe 321, then the conical cap 313 guides the mixed liquid, then the mixed liquid enters an annular cavity formed between the reducing pipe 310 and the inner wall of the regeneration tower 301, then the mixed liquid enters the inside of the circular truncated cone-shaped cylinder 501 through an overflow pipe 329 under the action of gravity, then the baffle plate 307 blocks the fluid formed by the mixed liquid, then the flow rate of the mixed liquid is reduced, then the mixed liquid flows downwards along the cavity between the oil separating plate 306 and the baffle plate 307, then the mixed liquid flows into the cavity on the left side of the oil separating plate 306, then the mixed liquid is layered gradually, then the low-density organic matters in the mixed liquid float upwards to form a light organic layer, the high-density organic matters in the mixed liquid gradually sink to form a heavy organic layer, the middle is a water layer, then the water layer moves rightwards through the water through holes 305, as the service life is prolonged, part of water can remain in the activated carbon, the height of the liquid level of the water layer is reduced, then the length of the cylindrical floater 78 immersed in the water is reduced, then the cylindrical floater 78 pulls the water replenishing conical plug 76 to move downwards through the linkage rod 77, then the conical water replenishing groove 72 is opened, then the
