Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, and in particular to a waste gas filtration mechanism and solid waste treatment equipment. Background Technology

[0002] Solid waste refers to waste that is no longer useful and has a solid state, generated during production, daily life and other activities. Waste gas is generated when treating waste gas, and it needs to be treated accordingly in order to meet environmental protection requirements.

[0003] A search revealed that the prior art discloses an exhaust gas filtration mechanism for solid waste treatment equipment (publication number: CN222468441U), which includes a housing. The inner cavity of the housing is equipped with a filter assembly for filtering exhaust gas. The inner cavity of the housing is also equipped with a cleaning assembly for cleaning the filter assembly. The bottom of the housing is provided with a collection assembly for collecting particulate matter in the exhaust gas.

[0004] Existing technologies mainly treat exhaust gas through filters and filter media. However, particulate matter in exhaust gas easily clogs the filters, requiring frequent cleaning. Relying solely on filtration for dust removal results in a heavy load on the filter media, a short lifespan, and a correspondingly short maintenance cycle. Therefore, there is room for optimization in existing technologies for treating particulate matter in exhaust gas.

[0005] Therefore, we propose an exhaust gas filtration mechanism and solid waste treatment equipment. Utility Model Content

[0006] The present invention mainly addresses the technical problem of frequent maintenance required for treating exhaust gas using filter media, and provides an exhaust gas filtration mechanism and solid waste treatment equipment.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a waste gas filtration mechanism and a solid waste treatment device, comprising:

[0008] The processing box has a cavity-like box structure;

[0009] An adsorption assembly, installed inside the treatment chamber, is used to treat waste gas. The adsorption assembly includes a partition, a spray pipe, a guide hood, a jet pipe, and branch pipes. The partition is fixedly installed to the treatment chamber and divides the chamber into dry and wet adsorption chambers. The dry adsorption chamber is equipped with filter media. The spray pipe is fixedly installed to the treatment chamber and located inside the wet adsorption chamber. The jet pipe is fixedly connected to the spray pipe. The guide hood is fixedly installed to the spray pipe. Several branch pipes are fixedly installed on the side wall of the jet pipe. The spray pipe can discharge waste gas into the wet adsorption chamber.

[0010] In a preferred embodiment of this utility model, the processing box is formed into a rectangular box, and a sealing cover is fixedly installed on the top of the processing box by screws. A fan is fixedly installed on the outside of the processing box, and the spray pipe is fixedly connected to the exhaust port of the fan.

[0011] In a preferred embodiment of this utility model, the spray pipe is formed into an L-shape, with the lower end of the spray pipe extending toward the bottom of the processing box, and the flow guide is fixedly connected to the lower end of the spray pipe.

[0012] In a preferred embodiment of this utility model, the flow guide is formed in the shape of a funnel, the jet pipe is fixedly connected to the smaller port of the flow guide, and the spray pipe is fixedly connected to the larger port of the flow guide.

[0013] In a preferred embodiment of this invention, the adsorption assembly further includes a jet head, the jet head is fixedly installed at the port of the branch pipe, the branch pipe obliquely penetrates the jet pipe, and the branch pipe forms a flat duckbill shape.

[0014] In a preferred embodiment of this utility model, an exhaust pipe connected to the dry adsorption chamber is fixedly installed on the outside of the treatment box, and two infusion pipes connected to the wet adsorption chamber are also fixedly installed on the outer wall of the treatment box.

[0015] A solid waste treatment device includes a treatment machine body, in which two counter-rotating crushing rollers are rotatably arranged, and an auger blade for conveying is rotatably connected inside the treatment box. All the above-mentioned exhaust gas filtration mechanisms are provided on the outside of the treatment machine body. The treatment box is fixedly installed on the outside of the treatment machine body, and a fan is connected to the chamber of the treatment machine body through a pipe.

[0016] Beneficial effects

[0017] This utility model provides a waste gas filtration mechanism and a solid waste treatment device. It has the following beneficial effects:

[0018] 1. This waste gas filtration mechanism and solid waste treatment equipment uses a fan to draw in waste gas, which is then forced into a spray pipe and discharged towards the bottom of the treatment box. The wet adsorption chamber is filled with liquid, such as water, which adsorbs and removes dust from the waste gas. The washed air passes through a partition and enters the dry adsorption chamber, where it is adsorbed by a filter material before being discharged. The filter material can be porous activated carbon, which has both washing and adsorption effects, greatly reducing waste gas emissions.

[0019] The jet pipe delivers air into the jet pipe and branch pipe. Due to the gradually narrowing design of the guide shroud opening, the air is compressed after entering the jet pipe, thus increasing the flow velocity. With high flow velocity and low pressure, the branch pipe draws liquid from the treatment chamber into the jet pipe and mixes it with the bundled airflow. Preliminary mixing and washing of the air is achieved in the jet pipe. After being discharged from the jet pipe, the air forms bubbles that float to the surface and are washed again by the liquid, improving the washing effect of the liquid on the airflow.

[0020] 2. This waste gas filtration mechanism and solid waste treatment equipment cuts the bundled airflow in the jet pipe through multiple flat spray heads, promoting gas-liquid contact and improving the gas washing effect.

[0021] 3. This waste gas filtration mechanism and solid waste treatment equipment has an exhaust pipe for discharging clean air from the dry adsorption chamber, and valves at the ends of two liquid infusion pipes. The two liquid infusion pipes are located near the top and bottom of the treatment tank, respectively. One liquid infusion pipe is connected to a water source for injecting water into the wet adsorption chamber, and the other liquid infusion pipe is used to discharge impurities from the wet adsorption chamber for easy maintenance. The leaf vein-shaped dispersion groove can further cut the airflow ejected from the jet pipe, disperse the airflow into multiple streams, and further promote the contact between gas and liquid for washing.

[0028] A waste gas filtration mechanism and solid waste treatment equipment, such as Figure 2 , Figure 3 and Figure 4 As shown, it includes:

[0029] The processing box 10 has a cavity-shaped box structure;

[0030] An adsorption assembly, installed inside the treatment chamber 10, is used to treat waste gas. The adsorption assembly includes a partition 11, a spray pipe 12, a flow guide shroud 13, a jet pipe 14, and branch pipes 15. The partition 11 is fixedly installed to the treatment chamber 10 and divides the chamber into dry and wet adsorption chambers. The dry adsorption chamber contains filter media. The spray pipe 12 is fixedly installed to the treatment chamber 10 and located inside the wet adsorption chamber. The jet pipe 14 is fixedly connected to the spray pipe 12. The flow guide shroud 13 is fixedly installed to the spray pipe 12. Several branch pipes 15 are fixedly installed on the side wall of the jet pipe 14. The spray pipe 12 is capable of... The exhaust gas is discharged into the wet adsorption chamber. The treatment box 10 forms a rectangular box. A sealing cover is fixedly installed on the top of the treatment box 10 by screws. A fan 17 is fixedly installed on the outside of the treatment box 10. The injection pipe 12 is fixedly connected to the exhaust port of the fan 17. The injection pipe 12 forms an L-shaped pipe. The lower end of the injection pipe 12 extends towards the bottom of the treatment box 10. The guide shroud 13 is fixedly connected to the lower end of the injection pipe 12. The guide shroud 13 forms a funnel shape. The jet pipe 14 is fixedly connected to the smaller end of the guide shroud 13. The injection pipe 12 is fixedly connected to the larger end of the guide shroud 13.

[0031] In this scheme, the exhaust gas is drawn in by the fan 17 and forced into the injection pipe 12. The exhaust gas is then discharged towards the bottom of the treatment box 10 through the injection pipe 12. The wet adsorption chamber is filled with liquid, such as clean water, which is used to adsorb and remove dust from the exhaust gas. The air after washing passes through the partition 11 and enters the dry adsorption chamber. After being adsorbed by the filter material, it is discharged. The filter material can be porous activated carbon, which has the dual filtration effect of washing and adsorption, greatly reducing the emission of exhaust gas.

[0032] The jet pipe 12 delivers air into the jet pipe 14 and the branch pipe 15. Due to the gradually narrowing design of the guide shroud 13, the air is compressed after entering the jet pipe 14, thereby increasing the flow velocity. With a high flow velocity and low pressure, the branch pipe 15 will draw the liquid in the treatment box 10 into the jet pipe 14 and mix it with the bundled airflow. The initial mixing and washing of the air is achieved in the jet pipe 14. After being discharged from the jet pipe 14, the air forms bubbles that float to the surface and are washed again by the liquid, thus improving the washing effect of the liquid on the airflow.

[0033] like Figure 5 As shown, the adsorption assembly also includes a nozzle 16. The nozzle 16 is fixedly installed at the port of the branch pipe 15. The branch pipe 15 obliquely penetrates the jet pipe 14 and forms a flat duckbill shape. The multiple flat nozzles 16 cut the bundle of airflow in the jet pipe 14, promote the contact between gas and liquid, and improve the gas washing effect.

[0034] like Figure 2 and Figure 3As shown, an exhaust pipe 19 connected to the dry adsorption chamber is fixedly installed on the outside of the treatment box 10. Two infusion pipes 20 connected to the wet adsorption chamber are also fixedly installed on the outer wall of the treatment box 10. A leaf vein-shaped dispersion groove 18 is opened at the bottom of the treatment box 10. The dispersion groove 18 is directly opposite the lower port of the jet pipe 12. The exhaust pipe 19 is used to discharge clean air from the dry adsorption chamber. Valves are provided at the ports of the two infusion pipes 20. The two infusion pipes 20 are respectively close to the top and bottom of the treatment box 10. One infusion pipe 20 is connected to a water source to inject water into the wet adsorption chamber. The other infusion pipe 20 is used to discharge impurities from the wet adsorption chamber for easy maintenance. The leaf vein-shaped dispersion groove 18 can cut the airflow ejected from the jet pipe 14 again, disperse the airflow into multiple streams, and further promote the contact between gas and liquid for washing.

[0035] like Figure 1 As shown, a solid waste treatment device includes a treatment machine body 30. Two counter-rotating crushing rollers are rotatably installed inside the treatment machine body 30. Meshing gears are fixedly installed at the ends of the two crushing rollers. A reduction motor is installed outside the treatment machine body 30, and the output shaft of the reduction motor is fixedly connected to one of the crushing rollers. An auger blade for conveying is rotatably connected inside the treatment chamber 10. The auger blade is driven by a motor outside the treatment machine body 30. Solid waste is shredded by the two crushing rollers and then conveyed to the outside of the treatment machine body 30 via the auger blade. All the aforementioned exhaust gas filtration mechanisms are installed outside the treatment machine body 30. The treatment chamber 10 is fixedly installed outside the treatment machine body 30. A fan 17 is connected to the chamber of the treatment machine body 30 via a pipe. By extracting exhaust gas from the waste during the crushing process and subjecting it to washing and adsorption treatment, the purified air is discharged from the exhaust pipe 19, reducing exhaust gas emissions and odor generation.

[0036] The working principle of this utility model is as follows: A geared motor is provided on the outside of the processing machine body 30. The output shaft of the geared motor is fixedly connected to one of the crushing rollers. An auger blade for conveying is also rotatably connected inside the processing box 10. The auger blade is driven by a motor outside the processing machine body 30. After the solid waste is torn up by the two crushing rollers, it is conveyed to the outside of the processing machine body 30 through the auger blade, thereby realizing the crushing treatment of solid waste.

[0037] Air is drawn in by the blower 17 and forced into the jet pipe 12. The exhaust gas is then discharged towards the bottom of the treatment chamber 10 through the jet pipe 12. The wet adsorption chamber is filled with liquid. The jet pipe 12 delivers air into the jet pipe 14 and the branch pipe 15. Due to the gradually narrowing design of the guide shroud 13, the air is compressed after entering the jet pipe 14, thus increasing the flow rate. With a high flow rate and low pressure, the branch pipe 15 draws the liquid in the treatment chamber 10 into the jet pipe 14 and mixes it with the bundled airflow. Preliminary mixing and washing of the air are achieved in the jet pipe 14. After being discharged from the jet pipe 14, the air forms bubbles that float to the surface and are washed again by the liquid. Multiple flat jet heads 16 cut the bundled airflow in the jet pipe 14, while the leaf vein-shaped dispersion groove 18 can cut the airflow ejected from the jet pipe 14 again, dispersing the airflow into multiple streams and promoting gas-liquid contact.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
