Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an adsorption and catalytic treatment device for organic waste gas. Background Technology

[0002] Organic waste gas is a general term for volatile organic compounds, which refers to organic solids or liquids that are easily volatilized into gaseous form at normal temperature and pressure. It mainly includes compounds such as alkanes, aromatics, esters, and aldehydes, such as benzene, toluene, xylene, and acetone.

[0003] For example, the Chinese authorized patent (Organic Waste Gas Purification Equipment) with announcement number CN213286001U includes a collection device, a filtration device, a concentration device, a heat exchange device, an incineration device, and an emission device. The collection device collects organic waste gas generated during the production process; the filtration device also includes plate filter units and bag filter units; the concentration device also includes an adsorption unit, a cooling unit, a concentration unit, a main air supply device, and a concentration air supply device; the incineration device also includes a combustion aid device and a purging device. This utility model is applicable to various fields of low-concentration, high-volume organic waste gas treatment.

[0004] However, in existing organic waste gas adsorption processes, most adsorption filter elements are integral and installed inside the adsorption box. When replacing them, the entire filter element needs to be replaced, which is wasteful and inconvenient to handle and replace. Therefore, it does not meet the current needs. To address this, we propose an organic waste gas adsorption and catalytic treatment device. Utility Model Content

[0005] The purpose of this utility model is to provide an organic waste gas adsorption and catalytic treatment device to solve the problems mentioned in the background art, where the adsorption filter element is mostly in the form of an integral piece and installed inside the adsorption box. When it needs to be replaced, the whole thing needs to be replaced, which is wasteful and inconvenient to take out and replace.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an organic waste gas adsorption and catalytic treatment device, comprising: an air inlet box and a base frame, wherein the air inlet box is mounted on the base frame, an air inlet is provided on one side surface of the air inlet box, a controller is provided at the front end of the air inlet box, an adsorption box is provided on the other side of the air inlet box, a desorption box is provided on one side of the adsorption box, a catalytic box is provided on one side of the desorption box, an adsorption fan is provided on one side of the catalytic box, a connecting pipe is provided between the top ends of the desorption box and the catalytic box, an installation opening is provided on the front surface of the adsorption box, an adsorption component is inserted into the installation opening, and a limit component is provided at the upper end of the adsorption box.

[0007] Preferably, the adsorption component includes a mounting frame, one side surface of which is provided with a mounting cavity that extends through the mounting frame, and multiple mounting cavities are provided, with an adsorption filler material embedded inside each mounting cavity.

[0008] Preferably, the adsorption assembly further includes a limiting outer plate, which is welded and fixed to the front surface of the mounting frame. The front surface of the limiting outer plate is provided with a push-pull handle, which is welded and fixed to the limiting outer plate.

[0009] Preferably, the limiting component includes a positioning sleeve, one end surface of which is provided with a moving groove, a moving column is inserted into the moving groove, and the moving column moves along the moving groove.

[0010] Preferably, a ball bearing is embedded inside one end of the movable column, a rotating column is embedded inside the ball bearing, and the rotating column is rotatably connected to the movable column through the ball bearing. A limit baffle is welded to one end of the movable column.

[0011] Preferably, the upper surface of the positioning sleeve and the bottom surface of the moving groove are provided with bolt holes. The limiting component also includes a fixing bolt. The upper surface of the moving column is provided with an adjustment groove in the form of vertical penetration. One end of the fixing bolt passes through the bolt hole and the adjustment groove on the upper surface of the positioning sleeve in sequence and is threadedly connected to the bolt hole on the bottom surface of the moving groove. The outer wall of the fixing bolt is provided with a lower pressure pad.

[0012] Preferably, the lower surface of the positioning sleeve is provided with a fixing base plate, and fixing screws are provided at the corners of the fixing base plate, and the fixing base plate is fixed to the adsorption box by fixing screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model achieves modularity by filling multiple adsorption fillers into the installation cavities at different positions during the installation of the adsorption assembly. This allows for the replacement of heavily adsorbed fillers, while less heavily adsorbed fillers can continue to be used, improving resource utilization, reducing resource waste, and lowering replacement costs. Then, push the push-pull handle to move the installation frame into the adsorption box. After moving it to the bottom, move the limiting baffle forward, and the moving column moves along the moving groove. When the limiting baffle moves to the front of the limiting outer plate, rotate the limiting baffle and then move the limiting baffle backward until the limiting baffle contacts the limiting outer plate. Tighten the fixing bolts and use the lower pressure pad to squeeze and fix the moving column, thereby fixing the limiting baffle. The limiting baffle limits the adsorption assembly, which is simple and convenient, improving the ease of installation and disassembly. It solves the problem that most adsorption filter elements in existing organic waste gas adsorption are integral and installed inside the adsorption box, requiring the entire filter to be replaced during replacement, resulting in serious waste and inconvenience in handling and replacement.

[0015] (2) By setting a moving groove at one end of the positioning sleeve, the moving column moves along the moving groove, which makes it easy to adjust the position of the limit baffle. Furthermore, by utilizing the characteristics of the moving column, it is easy to disassemble the moving column, thereby replacing the limit baffle without disassembling the entire limit assembly, which improves the convenience of replacement. A fixed base plate is set on the lower surface of the positioning sleeve, and the corner of the fixed base plate is fixed to the adsorption box by fixing screws, which facilitates the installation and disassembly of the limit assembly and improves the convenience of installation and disassembly.

An adsorption assembly 10 is inserted into an opening 11. The opening 11 facilitates the movement and replacement of the adsorption assembly 10. A limiting assembly 12 is provided at the upper end of the adsorption box 4 to limit the adsorption assembly 10, prevent it from slipping, and improve safety and stability. Organic waste gas enters the air intake box 1 through the air inlet 2 and is adsorbed by the adsorption assembly 10 installed inside the adsorption box 4. Then, it is further filtered by the desorption fan and molecular sieve rotor installed inside the desorption box 5. Then, it is subjected to high-temperature catalytic treatment by the oxidation furnace installed inside the catalytic box 6. Finally, the purified waste gas is discharged by the adsorption fan 8.

[0023] The adsorption assembly 10 includes a mounting frame 13. One side surface of the mounting frame 13 is provided with a mounting cavity 14, which extends through the mounting frame 13. Multiple mounting cavities 14 are provided, and adsorption filler 15 is embedded inside the mounting cavity 14. When installing the adsorption assembly 10, multiple adsorption fillers 15 are filled into the mounting cavities 14 at different positions to achieve modularity. In this way, when replacing, the adsorption filler 15 with severe adsorption can be replaced, while the less severe adsorption can continue to be used, thereby improving resource utilization, reducing resource waste, and reducing replacement costs.

[0024] The adsorption assembly 10 also includes a limiting outer plate 16, which is welded and fixed to the front surface of the mounting frame 13. The limiting outer plate 16 provides a limiting protection effect for the movement of the adsorption assembly 10, preventing continuous insertion. A push-pull handle 17 is provided on the front surface of the limiting outer plate 16, and the push-pull handle 17 is welded and fixed to the limiting outer plate 16. The push-pull handle 17 facilitates the back-and-forth movement of the adsorption assembly 10.

After it moves to the bottom, the limiting baffle 22 moves forward and the moving column 19 moves along the moving groove 29. When the limiting baffle 22 moves in front of the limiting outer plate 16, the limiting baffle 22 is rotated and then the limiting baffle 22 is moved backward until the limiting baffle is in front of the limiting outer plate 16. 22 contacts the limiting outer plate 16, tighten the fixing bolt 24, and rely on the lower pressure pad 28 to squeeze and fix the moving column 19, thereby fixing the limiting baffle 22. The limiting baffle 22 limits the adsorption assembly 10, which is simple and convenient and improves the convenience of installation and disassembly. When disassembling the adsorption assembly 10, first loosen the fixing bolt 24, then rotate the limiting baffle 22, and then move the limiting baffle 22 backward so that the limiting baffle 22 moves onto the adsorption box 4. Then the adsorption assembly 10 can be pulled out to replace the adsorption filler 15.
