Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device. Background Art

[0002] The waste tire pyrolysis technology utilizes the instability of organic matter in tires and sends the tires to a pyrolysis furnace for high-temperature heating. When heated to a certain temperature, the high-molecular compounds can be cracked into low-molecular compounds, among which the low-molecular compounds are pyrolysis oil, carbon black, steel wire and combustible gas.

[0003] During the tire pyrolysis process, because it is heated at high temperature, the exhaust gas is at a high temperature and contains hazardous substances. These wastewaters cannot be discharged directly and are prone to pollution, so they need to be treated. The existing technology can only achieve simple filtration of the exhaust gas, resulting in poor gas treatment effect. Not only is the exhaust gas treatment not comprehensive, but most of the exhaust gas requires secondary treatment, which increases the treatment cost and reduces efficiency. Utility Model Content

[0005] Furthermore, two fans are installed at the bottom of the trapezoidal box.

[0007] Furthermore, a second gas filter device is installed on the frame, the air inlet end of the second gas filter device is connected to the right conduction block through a pipeline, and the exhaust end of the second gas filter device is fixed with a return air pipe connected to the outer cylinder.

[0008] Furthermore, a water pump is installed on one side of the water tank, and a drainage pipe of the water pump is connected to the outer cylinder.

[0009] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0010] The exhaust gas treatment device introduces the discharged high-temperature exhaust gas into the outer cylinder through the exhaust pipe, guides the high-temperature exhaust gas to the air guide pipe through the connecting pipe, and cooperates with the fan to cool the high-temperature gas. The gas will then be filtered through the gas filter device, and then the filtered gas will be guided to the water tank through the fan to be neutralized with water. The overflowed exhaust gas is filtered through the gas filter cartridge and then discharged. Therefore, the filtering effect can be improved through cooling and multi-stage filtration, thereby improving efficiency and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-7In this embodiment, an exhaust gas treatment device includes a frame 1, an L-shaped water tank 2 is fixed on the table of the frame 1, and a trapezoidal box 3 opposite to the water tank 2 is fixed on the top, and an outer cylinder 7 and two gas filter devices 15 are respectively installed on the table. A filter cartridge 9 is fixed on the inner side of the outer cylinder 7, and an exhaust pipe 8 is fixed below the filter cartridge 9, and a support ring 10 is located above the filter cartridge 9. Three connecting pipes 11 are fixed on the inner side of the support ring 10 and penetrate the filter cartridge 9. The left and right sides of the trapezoidal box 3 are respectively Three interconnected conduction blocks 4 are fixed separately, and multiple air guide pipes 5 are connected and fixed between the two pairs of conduction blocks 4 on the left and right. The top exhaust end of the outer tube 7 is connected to one of the conduction blocks 4 on the left through a pipe, and the air inlet ends of the two gas filter devices 15 are respectively connected to the two conduction blocks 4 on the right through pipes. Fans 18 are installed on both sides of the protruding end of the water tank 2, and a gas filter cartridge 20 is installed on the top. The air guide end of the fan 18 extends to the inner bottom wall of the water tank 2, and the air suction end is connected to the exhaust end of the gas filter device 15.

[0021] In the above structure, high-temperature exhaust gas is introduced through the exhaust pipe, the exhaust gas enters the outer cylinder, and is guided to the air guide pipe through the connecting pipe. The high-temperature gas is dispersed through multiple air guide pipes, thereby improving the cooling effect. The exhaust gas then enters the gas filter device under the guidance of the conduction block to complete the exhaust gas filtration operation. The filtered gas will enter the water tank under the guidance of the fan and be neutralized with the water source. The excess gas will be filtered again through the gas filter cartridge to complete the gas discharge, thereby improving the efficiency of filtering the gas through multi-stage filtration, and completing the exhaust gas treatment at one time, which can also reduce the treatment cost.

[0022] Among them, two fans 6 are fixed to the bottom of the trapezoidal box 3 and distributed opposite to the air duct 5. After the high-temperature exhaust gas is dispersed through the air duct, the fans blow air to the air duct, thereby improving the efficiency of exhaust gas cooling.

[0023] In addition, a second gas filter device 16 is installed on the table of the frame 1 between the two first gas filter devices 15. The air inlet end of the second gas filter device 16 is connected to the right conduction block 4 through a pipe, and the exhaust end of the second gas filter device 16 is fixed with a return air pipe 19 connected to the outer cylinder 7, and the return air pipe 19 is located below the filter cylinder 9. The second gas filter device and the two first gas filter devices can reduce the load during filtration. The second gas filter device can receive the cooled exhaust gas and filter it at the same time. The filtered gas will be guided into the outer cylinder, pass through the air pipe again, and then be guided into the first gas filter device and the second gas filter device, so that circular filtration can be achieved while reducing the load. Therefore, the filtration effect is improved through circular filtration.

[0024] At the same time, a water pump 14 is installed on the front of the protruding end of the water tank 2. The water pump 14's suction pipe extends to the bottom of the water tank 2. The water pump 14's drainage pipe is connected to the outer cylinder 7. The drainage pipe is located above the filter cartridge 9. The bottom of the outer cylinder 7 is connected to a drainage pipe. The water pump can guide the wastewater in the water tank after neutralization with the exhaust gas into the outer cylinder, and the wastewater is filtered through the filter cartridge.

[0025] A float level gauge 13 extending into the interior of the outer cylinder 7 is installed on the outside of the outer cylinder 7. The float level gauge can monitor the water level in the lower part of the outer cylinder. When the drainage is slow and the water level reaches the float level gauge, the water pump stops pumping water, which can effectively prevent wastewater from being discharged through the exhaust pipe.

[0026] The working principle of the above embodiment is:

[0027] The exhaust gas is introduced into the outer cylinder through the exhaust pipe, and the exhaust gas goes from bottom to top, and is guided to the upper half of the outer cylinder through the connecting pipe, and then the exhaust gas is guided to the left conduction block through the pipe, and enters the right conduction block through the air guide pipe, and then the exhaust gas is guided to the two gas filter devices 1 and gas filter device 2 in turn through the three conduction blocks on the right. At the same time, gas filter devices 1 and 2 both filter the exhaust gas, and the fan runs to draw the exhaust gas filtered in gas filter device 1 into the water tank to neutralize the impurities in the exhaust gas with water. The excess gas will be filtered through the gas filter cartridge and then exhausted. At the same time, the gas filtered by the gas filter device 2 is guided to the outer cylinder through the return pipe to realize circulation, and then the above filtration is repeated. After filtration, the water source in the water tank is extracted by the water pump and guided into the outer cylinder, and then the filtration and discharge of the water source is completed through the filter cartridge.

[0028] In summary, the exhaust gas can be treated in multiple stages at one time, thereby effectively improving the filtering effect and avoiding increasing the filtering cost multiple times.
