Description

Technical Field

[0001] This utility model belongs to the field of waste gas purification technology, and specifically relates to a waste gas purification device based on a zeolite rotor. Background Technology

[0002] Zeolite rotors concentrate large volumes of low-concentration waste gas into high-concentration, low-volume waste gas, thereby reducing equipment investment and operating costs and improving the efficiency of VOCs waste gas treatment. However, existing zeolite rotor waste gas purification devices suffer from the following technical problems: 1) The zeolite molecular sieve is too highly integrated. While the integrated design is convenient during manufacturing, it significantly increases maintenance time and costs, and prevents quick local replacement; 2) Existing zeolite rotor molecular sieves lack pre-filters, causing dust and other particulate matter in the waste gas to adhere directly to the zeolite molecular sieve, easily clogging its pores. This not only makes cleaning difficult but also affects the service life of the zeolite molecular sieve.

[0003] A search revealed existing technology patent number CN201510872488.1, authorization announcement number CN105344173B, entitled "A Dust Removal Device for Air Filters," which specifies that existing air filter dust removal devices, such as... Figure 1 As shown, the device includes a dust removal motor 03 adapted to be fixedly mounted on the indoor-facing side of an air filter 01. The dust removal motor 03 has a motor shaft 02 extending out of the air filter 01 and located outdoors. A dust removal brush 04 is fixedly mounted on the motor shaft 02, with the bristles of the dust removal brush 04 in close contact with the outer surface of the air filter 01. When dust removal is required, the dust removal motor 03 is started, and the motor shaft 02 drives the brush 04 to rotate. The bristles of the brush 04 rotate and sweep the outer surface of the air filter 01, removing the adhering dust.

[0004] A search revealed that the prior art CN 221412672U discloses a zeolite rotary adsorption device, which has the following technical problems during use: during the cleaning process of the filter cylinder in the filter box by the reciprocating motion of the cleaning roller, dust and other particulate matter cannot fall to the bottom of the filter cavity in time. Due to its light weight, it will be blown up by the continuous air intake, resulting in a large amount of dust and other particulate matter floating in the filter box, which affects the filtration effect.

[0005] For example, the existing technology CN217795366U discloses a rotary zeolite molecular sieve, which has the following technical problems during use: 1) The lack of a pre-filter device easily causes blockage of the ring-shaped molecular sieve, affecting the normal use of the zeolite molecular sieve; 2) Although the ring-shaped molecular sieve can be quickly replaced locally, due to the setting of the baffle and bolts, the connecting seat and the outer shell cannot fit together, resulting in poor sealing. During hot air desorption, the desorbed gas needs to be blown outward from the inside, which easily causes convection due to the pressure difference with the gas to be treated, resulting in poor final treatment effect. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a zeolite rotor-based exhaust gas purification device. Through the disc-type modular design, it is not only convenient to transport, but also greatly reduces maintenance costs. At the same time, a filter plate and a cleaning mechanism are added in the air inlet direction to prevent dust particles from damaging the zeolite molecular sieve box, which not only further reduces maintenance costs, but also improves exhaust gas treatment efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A zeolite rotor-based waste gas purification device includes a frame, a rotating support, a fixed frame, a zeolite molecular sieve box, a motor I, a desorption duct, a cooling duct, an inlet pipe, an outlet pipe, a support frame, a mounting plate, a movable support, a filter plate, a motor II, a cleaning mechanism, and a collection box. The frame is equipped with a protective cover, inside which the rotating support is movably mounted. A synchronous pulley at one end of the rotating support's shaft is connected to a synchronous pulley at the output end of motor I via a synchronous belt. Motor I is fixedly mounted on the frame. The rotating support is equipped with guide bars, and limit switches are provided on the guide bars. A fixed frame is movably placed on the rotating support along the guide strip. The fixed frame contains a zeolite molecular sieve box. The outer side of the protective cover is fixedly connected to the desorption air duct, cooling air duct, air inlet pipe, and air outlet pipe. The positions of the air inlet pipe and the air outlet pipe are corresponding. A support frame is provided above the air inlet pipe. A mounting plate is provided inside the support frame. A movable support is movably installed on the mounting plate. Several filter plates are provided on the movable support. The synchronous pulley at one end of the movable support shaft is connected to the synchronous pulley at the output end of motor II through a synchronous belt. A cleaning mechanism is provided on one side of the movable support. A collection box is provided at the bottom of the cleaning mechanism.

[0009] The cleaning mechanism includes a guide groove, a rack, a movable plate, brushes, gears, an electric telescopic rod, a sealing cover, and a fixed baffle. The guide groove is installed on the fixed baffle, which is installed inside the air intake pipe. The movable plate is movably installed inside the guide groove, and several brushes are provided on the movable plate. A gear at one end of the brush shaft meshes with the rack, which is installed inside the guide groove. An electric telescopic rod is provided between the two sets of guide grooves. The telescopic end of the electric telescopic rod is fixedly connected to the movable plate, and a sealing cover is fitted on the outside of the telescopic end of the electric telescopic rod.

[0010] An inspection door is provided on one side of the protective cover to facilitate maintenance of the internal structure by staff.

[0011] The fixing frame has symmetrical fixing blocks on both sides. A locking pin is movably installed on one side of the fixing block. A pressing plate is installed on the other side of the locking pin by bolts. A spring is connected to one end of the locking pin.

[0012] The collection box has a handle on one side, making it convenient for staff to pick up and handle it.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1) By modularizing the zeolite rotor into several independent zeolite molecular sieve boxes, the staff can adjust the position of the pressing plate to compress the locking pin spring and disengage it from the upper limit port of the guide bar, thus completing the overall removal of the fixing frame. This allows for partial replacement, which not only reduces maintenance costs but also reduces maintenance time and improves the efficiency of waste gas treatment.

[0015] 2) The electric telescopic rod drives the movable plate to reciprocate in the guide groove, which in turn drives the brush on the movable plate to clean the rotating filter plate. During the movement, the brush on the movable plate reciprocates during the meshing of the gear and rack, which can further improve the cleaning effect and extend the service life of the filter plate. The dust and other particles swept off will fall into the collection box below through the channel on one side of the fixed baffle for unified collection and treatment. At the same time, the fixed baffle can also prevent the exhaust gas from blowing up the dust and other particles, thus improving the filtration effect. Attached Figure Description

By modularizing the zeolite rotor into several independent zeolite molecular sieve boxes 14, partial replacement can be performed, reducing maintenance costs.

[0027] The cleaning mechanism 25 includes a guide groove 251, a rack 252, a movable plate 253, brushes 254, gears 255, an electric telescopic rod 256, a sealing cover 257, and a fixed baffle 258.
