Technical Field

[0002] Air pollution is one of the most prominent environmental problems in my country, and industrial waste gas is the main source of air pollution. With the increase of people's environmental awareness, traditional waste gas treatment equipment is no longer sufficient to fully treat industrial waste gas and cannot meet the requirements of zero emission and zero pollution. Zeolite wheel adsorption concentration device is a new type of efficient waste gas adsorption equipment, which has a strong ability to adsorb organic solvents, and the purification efficiency of waste gas can reach more than 98%, and it can greatly reduce the workload of subsequent equipment.

[0003] Therefore, factories often use zeolite wheel equipment to adsorb exhaust gas. The zeolite wheel equipment concentrates VOCs and then desorbs the organic matter adsorbed on the zeolite wheel through airflow. The desorbed clean air is discharged to the outside, and the concentrated VOCs are desorbed and introduced into the incinerator for incineration. The zeolite wheel rotates repeatedly to continuously adsorb, compress, desorb and separate the VOC treatment steps, so it can work continuously.

[0004] In the prior art, when the filter screen is pre-filtering VOC substances, some of the residual filter residues will clog the filter screen, thereby reducing the efficiency of treating exhaust gas and affecting subsequent use. For this reason, we propose a zeolite wheel adsorption device. Utility Model Content

[0025] Embodiment 1:

[0026] Reference Figure 1A zeolite rotor adsorption device includes a ventilation box 1 connected to the air inlet end of the zeolite rotor body. The zeolite rotor body is a new and efficient waste gas adsorption equipment. It has a strong ability to adsorb organic solvents, can improve the purification efficiency of waste gas, and can greatly reduce the workload of subsequent equipment. This is a prior art. The ventilation box 1 can be connected to the air inlet end of the zeolite rotor equipment to pre-treat the gas entering the zeolite rotor body, and an air inlet duct is also provided on the ventilation box 1 for connecting with the equipment generating waste gas.

[0027] Embodiment 2:

[0028] Reference Figure 1-Figure 4 An intercepting net 2 is also fixedly connected in the ventilation box 1, and a reciprocating screw 5 is rotatably connected to the ventilation box 1, a cleaning plate 6 is threadedly connected to the reciprocating screw 5, a cleaning brush 7 is also fixedly connected to the cleaning plate 6, and the contact end of the cleaning brush 7 is in contact with the air inlet end face of the intercepting net 2, a nozzle 8 is fixedly connected to the cleaning plate 6, and a cavity connected to the nozzle 8 is opened in the cleaning plate 6.

[0029] A boost cylinder 9 is also fixedly connected to the ventilation box 1, and a boost rod 901 is slidably connected to the boost cylinder 9. A piston 902 is provided at one end of the boost rod 901, and the piston 902 fits against the inner wall of the boost cylinder 9. The other end of the boost rod 901 is fixedly connected to the cleaning plate 6. An air inlet pipe and an air outlet pipe are respectively provided on the boost cylinder 9. Both the air inlet pipe and the air outlet pipe are provided with a one-way valve, and then the nozzle 8 is connected to the air outlet pipe.

[0030] When the reciprocating screw 5 rotates, the cleaning plate 6 moves back and forth and up and down in the ventilation box 1. At this time, the boost rod 901 will move upward with the cleaning plate 6, and the boost rod 901 will drive the piston 902 to move, compressing the gas in the boost cylinder 9. At this time, the air inlet pipe stops taking in air, and the air outlet pipe will compress the gas into the cavity inside the cleaning plate 6, and the gas will be transported to the nozzle 8 through the cavity. At this time, the nozzle 8 sprays toward the air inlet end face of the interception net 2. When the boost rod 901 moves downward with the cleaning plate 6, the boost rod 901 will drive the piston 902 to move, and the cavity in the boost cylinder 9 will produce negative pressure, and the air inlet pipe will transport the outside gas into the boost cylinder 9. During this process, the air inlet pipe can only take in air, and the air outlet pipe stops exhausting air.

[0031] A connecting plate is also provided in the ventilation box 1, on which a rotatable shaft 3 is provided, on which a fan blade 301 is fixedly connected, a connecting shaft 4 is rotatably connected to the ventilation box 1, the connecting shaft 4 and the shaft 3 are meshed with bevel gears, a main pulley 401 is fixedly connected to the connecting shaft 4, an auxiliary pulley 501 is fixedly connected to the reciprocating screw 5, and the main pulley 401 is connected to the auxiliary pulley 501 through a belt.

[0032] The working principle is as follows: when the zeolite rotor equipment adsorbs exhaust gas, a ventilation box 1 is connected to the air inlet end of the zeolite rotor body. At this time, the ventilation box 1 can be connected to the equipment that generates the exhaust gas, and then the zeolite rotor equipment is started. The exhaust gas enters the zeolite rotor body through the ventilation box 1. At this time, the exhaust gas will first pass through the interception net 2 for interception and filtration.

[0033] During this process, the fan blades 301 will drive the rotating shaft 3 to rotate, and the rotating shaft 3 will drive the connecting shaft 4 to rotate through the bevel gear. Then the connecting shaft 4 will drive the reciprocating screw 5 to rotate through the pulley. At this time, the reciprocating screw 5 will drive the cleaning plate 6 to move up and down. At this time, the cleaning plate 6 will drive the cleaning brush 7 to brush and clean the impurities on the interception net 2, and perform contact cleaning on the pores on the surface of the interception net 2, so as to improve the cleaning effect and reduce the amount of residual filter residue blocking the filter screen, thereby improving the efficiency of the zeolite wheel equipment in treating waste gas.

[0034] In addition, a collecting box 101 is fixedly connected to the bottom of the ventilation box 1. The collecting box 101 is connected to the ventilation box 1 through a through hole, and the through hole is arranged on one side of the air inlet end of the intercepting net 2. Impurities can be collected centrally through the collecting box 101.

[0035] When the cleaning plate 6 moves up and down, the nozzle 8 cooperates with the cleaning brush 7 to clean the filter residue on the surface of the interception net 2, so that the air is sprayed to the pores on the surface of the interception net 2, so that the cleaning brush 7 can better clean the surface of the interception net 2.
