The barrel body 1 is slidably connected to a plurality of groups of second curved plates 18 in the middle part, and a group of second curved plates 18 slides up and down around the cylinder 13; the first curved plates 17 and the second curved plates 18 are of the same size, and a group of first curved plates 17 and second curved plates 18 are staggeredly distributed outside the cylinder wall of the cylinder 13; a group of the first through holes 15 and the first curved plates 17 correspond to the positions of the second curved plates 18; the first curved plates 17 and the second curved plates 18 are both provided with first through grooves 19, and the first through grooves 19 are fixed with activated carbon layers 191; the first curved plates 17 and the second curved plates 18 move up and down staggeredly through the lifting parts; the first curved plates 17 and the second curved plates 18 are staggeredly moved up and down by the lifting parts; The first through hole 15 and the second through hole 16 are both blocked by a shielding member; a spray member is provided in the adsorption chamber 11; an exhaust pipe 2 is fixedly connected to the top of the cylinder 13, and the top of the exhaust pipe 2 extends out of the barrel body 1, and a group of exhaust pipes 2 are interconnected; an air inlet pipe 23 is fixedly connected to the bottom of the cylinder 13, and the bottom of the air inlet pipe 23 extends out of the barrel body 1; a first air outlet pipe 21 is fixedly connected to the top side wall of the barrel body 1, and the first air outlet pipe 21 and the adsorption chamber 11 are interconnected; a liquid outlet pipe 22 is fixedly connected to the side wall of the barrel body 1, and the liquid outlet pipe 22 and the adsorption chamber 11 are interconnected; a second air outlet pipe 24 is fixedly connected to the side wall of the barrel body 1, and the second air outlet pipe 24 and the steam outlet pipe 24 are connected to the side wall of the barrel body 1. The desorption chambers 12 are interconnected; in the prior art, when treating VOCs waste gas in sewage waste gas, activated carbon is generally used for adsorption and spraying chemical agents are used to treat VOCs waste gas, but there are the following problems: due to the limited adsorption effect of activated carbon, desorption treatment is required, but when treating VOCs waste gas, VOCs waste gas is continuously treated, and frequent manual replacement of activated carbon and multiple switching of VOCs waste gas are required, which will greatly reduce the purification efficiency of VOCs waste gas. At the same time, when the activated carbon cannot be replaced in time, part of the VOCs waste gas will escape without being adsorbed by the activated carbon, resulting in incomplete purification;For this reason, when the present invention is working, the VOCs waste gas enters the cylinder 13 through the waste gas pipe 2. Since the cylinder 13 is isolated by the partition 14, the waste gas will escape through the first through hole 15 at this time. At this time, most of a group of first curved plates 17 are located in the adsorption chamber 11 and cover the peripheral wall of the cylinder 13. At the same time, most of the second curved plates 18 are located in the steam desorption chamber 12 and cover the peripheral wall of the cylinder 13. At the same time, the first through hole 15 not covered by the first curved plate 17 will be covered by the shielding member, so the waste gas will escape from the first through hole 15 and then be adsorbed in the activated carbon layer of the first curved plate 17. At the same time, the second through hole 16 not covered by the second curved plate 18 will be covered by the shielding member, so the steam or hot air will enter from the air inlet pipe 23 and escape through the second through hole 16 (steam or hot air). The wind enters through the air inlet pipe 23, and the steam and hot air generation are both existing technologies and will not be elaborated). Finally, the activated carbon layer 191 in the second curved plate 18 is desorbed. After the activated carbon layer 191 on the first curved plate 17 in the adsorption chamber 11 is in a saturated state, a group of first curved plates 17 and a group of second curved plates 18 are moved up and down alternately by the lifting member, so that the desorbed second curved plate 18 enters the adsorption chamber 11, and the saturated first curved plate 17 enters the steam desorption chamber 12. Then, the above operation is used to treat the exhaust gas and desorb the activated carbon layer 191. At the same time, after being adsorbed by the activated carbon layer 191, a secondary spraying treatment will be carried out through the spraying member to ensure the thorough treatment of the VOCs exhaust gas and the purification of the gas. ;

[0046] A VOCs waste gas adsorption treatment method for urban sewage treatment, which is applicable to the above-mentioned VOCs waste gas adsorption treatment device for urban sewage treatment, is as follows:

[0047] S1: VOCs waste gas is introduced through the waste gas pipe, and the waste gas is adsorbed by the activated carbon layer of the first curved plate, and then sprayed through the spray part, and the treated gas is discharged through the first outlet pipe;

[0048] S2: After the activated carbon layer of the first curved plate is saturated with adsorption, the first curved plate and the second curved plate are driven to move up and down alternately by the lifting member, so that the activated carbon layer of the first curved plate is located in the steam adsorption chamber for desorption operation, and the activated carbon layer of the second curved plate is adsorbed;

[0049] S3: Repeat the above operation to complete the desorption of the activated carbon in the activated carbon layer without stopping the machine.

[0050] Working principle: VOCs waste gas enters the cylinder 13 through the waste gas pipe 2. Since the cylinder 13 is isolated by the partition 14, the waste gas will escape through the first through hole 15. At this time, most of the first curved plates 17 are located in the adsorption chamber 11 and cover the peripheral wall of the cylinder 13. At the same time, most of the second curved plates 18 are located in the steam desorption chamber 12 and cover the peripheral wall of the cylinder 13. At the same time, the first through hole 15 not covered by the first curved plate 17 will be covered by the shielding member, so the waste gas will escape from the first through hole 15. The steam or hot air will escape from the first through hole 15 and then be adsorbed by the activated carbon layer of the first curved plate 17. At the same time, the second through hole 16 not covered by the second curved plate 18 will be covered by the shielding member, so the steam or hot air will enter from the air inlet pipe 23 and escape through the second through hole 16 (the steam or hot air will enter through the air inlet pipe 23, and the generation of steam and hot air is the prior art and will not be described). Finally, the activated carbon layer 191 in the second curved plate 18 is desorbed, and then the activated carbon layer 191 in the second curved plate 18 is desorbed. After the activated carbon layer 191 on an arc plate 17 is in a saturated state, a group of first arc plates 17 and a group of second arc plates 18 are moved up and down alternately through the lifting member, so that the second arc plate 18 that has been desorbed enters the adsorption chamber 11, and the first arc plate 17 in a saturated state enters the steam desorption chamber 12, and then the exhaust gas is treated and the activated carbon layer 191 is desorbed through the above operation. At the same time, after adsorption by the activated carbon layer 191, a secondary spray treatment will be carried out through the spray member to ensure that the VOCs exhaust gas is thoroughly treated to ensure the purification and discharge of the gas; because when the first arc plate 17 and the second arc plate 18 are alternately moved, the first through hole 15 is in a sealed state, or when the activated carbon layer is insufficiently permeable, the air pressure in the cylinder 13 increases, so that the sealing plate 72 moves up, and the push rod 71 is supported against the horizontal surface of the inverted L-shaped plate 7, so that the pressure sensor is started, and the warning light is turned on, and the valve of the exhaust pipe 2 is closed at the same time to avoid safety accidents.
