Description

Technical Field

[0001] The utility model relates to the technical field of industrial tail gas treatment equipment, in particular to a zeolite drum waste gas treatment equipment. Background Art

[0002] With the continuous progress of society, the industrial field is constantly developing. When treating some large-volume, low-concentration organic waste gases, in order to reduce operating costs, zeolite drum catalytic combustion waste gas treatment equipment is often used to adsorb and concentrate the organic waste gases.

[0003] After using the zeolite drum to adsorb industrial waste gas, hot air needs to be introduced into the zeolite drum to desorb the dust on the surface of the zeolite drum. After desorption, the zeolite molecular sieve in the zeolite drum will be in a high temperature state, and the zeolite molecular sieve with too high temperature has no adsorption effect. The existing cooling equipment directly uses a pipe to introduce cold air into the zeolite drum to cool the zeolite molecular sieve, which can easily lead to the zeolite molecular sieve being unable to be cooled quickly and evenly. The zeolite molecular sieve at the same horizontal height of the cold air pipe will be cooled quickly, and other positions cannot be cooled quickly. In order to ensure that the zeolite molecular sieve is cooled quickly and evenly, it is necessary to design a zeolite drum waste gas treatment equipment. Utility Model Content

[0022] The front and rear ends of the zeolite drum 15 are equipped with cooling mechanisms, which include a cold air machine 11, a T-type connecting pipe 6, a first nozzle 10 and a shunt pipe 9. The right end of the box 1 is fixedly connected with the cold air machine 11, and the air outlet end of the cold air machine 11 is fixedly connected with the T-type connecting pipe 6. Two shunt pipes 9 distributed front and back about the zeolite drum 15 are fixedly installed inside the box 1. The two ends of the T-type connecting pipe 6 away from the cold air machine 11 are respectively fixedly connected to the two shunt pipes 9 and are connected to each other. The circumferential surfaces of the two shunt pipes 9 are fixedly connected with a plurality of first nozzles 10 distributed up and down, and the plurality of first nozzles 10 are all facing the zeolite drum 15. During operation, the zeolite molecular sieve can be cooled more evenly and quickly by the cooperation of the cooling mechanism and the angle adjustment mechanism.

[0023] Furthermore, the angle adjustment mechanism includes a motor 16, a gear 17 and teeth 5. The bottom end of the housing 1 is fixedly connected with the motor 16. The output shaft end of the motor 16 extends upward into the housing 1 and is rotatably connected with the housing 1. The output shaft end of the motor 16 is fixedly connected with the gear 17. The circumferential surface of the zeolite drum 15 is fixedly connected with a plurality of teeth 5, and the plurality of teeth 5 mesh with the gear 17. When working, the motor 16 drives the gear 17 to rotate, and the zeolite drum 15 can be driven to rotate with the cooperation of the teeth 5. This not only facilitates the zeolite molecular sieves at different positions in the zeolite drum 15 to uniformly adsorb the industrial waste gas entering from the first air inlet pipe 2, but also allows the zeolite molecular sieves at different positions to uniformly contact with the cool air sprayed from the first nozzle 10, thereby completing a rapid and uniform cooling work.

[0024] Furthermore, the bottom end of the box body 1 is fixedly connected with a base 4, the height of the base 4 is greater than the height of the motor 16, and the motor 16 is located in the base 4. When working, under the action of the base 4, not only can the box body 1 be stably placed on the ground, but also a space for the motor 16 to be placed can be provided.

[0025] Furthermore, the inner filter cartridge 8 is a breathable mesh cartridge, and the contact ends of the inner filter cartridge 8 and the zeolite drum 15 are sealed by a sealing ring. During operation, there is a good sealing effect between the inner filter cartridge 8 and the zeolite drum 15.

[0026] Furthermore, the desorption mechanism includes a second air inlet pipe 7, a diverter shell 13 and a second nozzle 14. The top of the box body 1 is fixedly connected to the second air inlet pipe 7 through a fixed seat, the inner wall of the inner filter cartridge 8 is fixedly connected to the diverter shell 13 through a support plate, the second air inlet pipe 7 is fixedly connected to the diverter shell 13 and are interconnected, one end of the diverter shell 13 close to the inner wall of the inner filter cartridge 8 is fixedly connected to a plurality of second nozzles 14, the right end of the box body 1 is fixedly connected to the discharge pipe 3, the second nozzle 14 faces the side where the discharge pipe 3 is located, and the discharge pipe 3 is externally connected to a dust collection device. During operation, the second air inlet pipe 7 is externally connected to a hot air blower, and the hot air brought by the hot air blower enters the diverter shell 13 along the second air inlet pipe 7, and is finally ejected from multiple second nozzles 14. The ejected hot air is directly blown to the rotating zeolite drum 15 through the inner filter cartridge 8, so that the dust adsorbed in the zeolite molecular sieve falls off. At the same time, the discharge pipe 3 is externally connected to a dust collection device, and the dust collection device absorbs the fallen dust from the discharge pipe 3 to the outside, so that the cleaning work of the zeolite molecular sieve can be completed.

[0027] Furthermore, the inner wall of the box body 1 is fixedly connected with a guide plate 12, and the guide plate 12 is located on the side where the discharge pipe 3 is located, and the side of the guide plate 12 close to the zeolite drum 15 is provided with an inclined surface, and the inclined surfaces are inclined downward from top to bottom.

[0028] Working principle:

[0029] When in use, the angle adjustment mechanism drives the zeolite drum 15 to rotate, and then the exhaust gas is introduced into the interior of the housing 1 through the first air inlet pipe 2. The exhaust gas is first processed by the zeolite drum 15, then enters the inner filter drum 8, and is finally discharged to the outside. When the exhaust gas is processed, the desorption mechanism is connected to an external hot air blower and a dust collection device to desorb the dust on the surface of the zeolite molecular sieve. After the processing is completed, the cooling mechanism quickly and evenly cools the zeolite drum 15 so that the zeolite drum 15 can quickly carry out the next round of exhaust gas processing operations.
