Description

Technical Field

[0001] This utility model relates to the technical field of organic waste gas treatment equipment, and in particular to an adsorption filter box that can be combined with a zeolite rotor. Background Technology

[0002] In industries such as semiconductors, chemicals, pharmaceuticals, printing, and coating, zeolite rotors are used to treat VOC-containing waste gases generated during production. They concentrate low-concentration, high-volume waste gases into high-concentration, low-volume gases, allowing for more efficient subsequent treatment using methods such as incineration or catalytic oxidation to achieve emission standards. The technical characteristics of zeolite rotors include: high efficiency and energy saving, wide applicability, high adsorption efficiency, good stability, and no environmental pollution.

[0003] However, VOC-containing waste gas has a complex composition. If the waste gas is not pretreated, high-boiling-point substances may clog the pores of the zeolite rotor, reducing its adsorption performance, increasing operating costs, and even affecting the stability and reliability of the entire treatment system. Therefore, pretreatment of waste gas is a crucial step to ensure the normal operation of the zeolite rotor and efficient waste gas treatment.

[0004] For exhaust gases containing high-boiling-point substances, the conventional technique is to set up a separate adsorption filter box before the zeolite rotor. However, this design of the adsorption filter box has the disadvantages of large footprint and high cost.

[0005] Furthermore, a patent document with publication number CN220026562U proposes a zeolite concentrator rotor pretreatment device. Its technical solution involves installing a housing to house both the filter assembly and the zeolite rotor. This technology, by combining the filter assembly and the zeolite rotor within the housing, can pretreat waste gas. However, its disadvantages include inconvenient maintenance of the zeolite rotor, a large housing size, and high cost.

[0006] In addition to the two points mentioned above, existing adsorption filter boxes also have the following problems: In adsorption filter boxes that handle small air volumes, the activated carbon is mostly installed in a drawer-type configuration, pulled out from the side, and replaced from the outside of the box; however, in adsorption filter boxes that handle large air volumes, it cannot be pulled out from the side and can only be pulled out from inside the box. The ladders installed inside existing adsorption filter boxes are usually fixed, and the activated carbon can only be replaced near the ladder, thus making maintenance and activated carbon replacement inconvenient.

The plate mounting frame 16 is used; the plate mounting frame 16 and each G4 mesh plate 17 are fixedly connected by bolts; two sliding ladders 14 are provided inside the adsorption filter box 1, each sliding ladder 14 including a first-level ladder 141 and a second-level ladder 142; the first-level ladder 141 is located in front of the activated carbon assembly mechanism 15, facilitating personnel to replace activated carbon; the second-level ladder 142 is located between the activated carbon assembly mechanism 15 and the G4 mesh plate 17, facilitating personnel to replace activated carbon and G4 mesh plates; the sliding ladder 14 includes a U-shaped slide rod and a ladder, the U-shaped slide rod is fixedly connected to the top shell 11 of the adsorption filter box by bolts, and the top of the sliding ladder 14 upright is set as a hook, allowing the ladder to move left and right along the U-shaped slide rod; this design makes it easy to replace all the activated carbon and G4 mesh plates inside the adsorption filter box 1.

[0024] An air inlet 12 is provided at the center of the left side of the adsorption filter box 1; the air outlet of the adsorption filter box 1 is located on the right side of the housing 11.

[0025] The shell 11 of the adsorption filter box 1 is divided into upper and lower boxes, which are connected by an inner flange and the inner flange is fixed by bolts.

[0026] The top of the adsorption filter box 1 is designed in a V-shape, with a higher center and lower sides to prevent water or snow accumulation on the top of the adsorption filter box.

[0027] The activated carbon assembly mechanism 15 includes a mounting frame 151, a front sealing plate 152, a rear sealing plate 153, and an activated carbon module box 154. The activated carbon module boxes 154 are arranged in layers on the mounting frame 151; one end of the activated carbon module box 154 is provided with a handle; the left end of the mounting frame 151 is provided with a filter air inlet, and the front sealing plate 152 is provided on the air inlet side of the mounting frame 151; the right end of the mounting frame 151 is provided with a filter air outlet, and the rear sealing plate 153 is provided on the air outlet side of the mounting frame 151; the front sealing plate 152 and the rear sealing plate 153 are staggered.

[0030] Working principle: Organic waste gas enters the interior of the adsorption filter box 1 through the air inlet 12, and then enters the activated carbon assembly 15 through the gap of the front sealing plate 152. High boiling point substances in the organic waste gas are adsorbed by the activated carbon. During the entry process, the organic waste gas flows up and down through the activated carbon module box 154, and then exits through the gap of the rear sealing plate 153.

[0031] The gas then passes through the G4 mesh plate 17 for dust removal before entering the zeolite rotor. The G4 mesh plate 17 serves to intercept dust particles and distribute air evenly, which helps extend the service life of the zeolite rotor and improve its adsorption efficiency.
