Abstract

This utility model discloses a waste gas treatment device for chemical processing, including a waste gas treatment tank. An exhaust pipe is connected to the left side of the waste gas treatment tank, a filter pipe is connected to the top of the tank, a booster pipe is connected to the top of the filter pipe, and a treatment pipe is connected to the top of the booster pipe. This utility model uses a dual-head motor to drive a shaft and a booster fan to rotate. The rotation of the shaft drives an activated carbon plate and a drying plate to rotate inside the treatment pipe to treat the waste gas. Simultaneously, the rotation of the activated carbon plate and the drying plate drives a rubber brush to rotate and flush the inner wall of the treatment pipe, preventing dust from adhering to the pipe wall. The fan blows the waste gas inside the treatment pipe towards the filter pipe, and then the waste gas passes through the filter element before entering the waste gas treatment tank. This prevents dust in the waste gas from adhering to the inner wall of the pipe, increases the air intake, and thus accelerates the waste gas treatment speed and improves treatment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically a waste gas treatment device for chemical processing. Background Technology

[0002] Flue gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common types of flue gas purification include factory flue gas purification, workshop dust gas purification, organic waste gas purification, odor removal, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] A search revealed that Chinese patent application number 202320565657.7 discloses a waste gas treatment device for chemical processing, comprising a waste gas treatment tank, an inlet pipe, and an exhaust pipe. The inlet pipe is connected to one side of the top of the waste gas treatment tank, and the exhaust pipe is connected to the other side of the top of the waste gas treatment tank. A filter box is provided on the inlet pipe, and guide rails are symmetrically arranged inside the filter box. A desiccant plate is movably inserted into the inner cavity of the guide rails. An activated carbon plate is provided below the desiccant plate, and heating mesh plates are provided on the lower surfaces of both the activated carbon plate and the desiccant plate. This patented technology utilizes a desiccant plate to absorb moisture from waste gas. The dried waste gas then enters an activated carbon plate, where the activated carbon absorbs harmful substances. After treatment, the waste gas is discharged through an exhaust pipe. Both the desiccant plate and the activated carbon plate have heating mesh plates installed on their bottom surfaces. These heating mesh plates heat the desiccant and activated carbon inside the desiccant and activated carbon plates, accelerating the evaporation of moisture and ensuring effective waste gas treatment.

[0004] Although the aforementioned patent utilizes a desiccant plate to absorb moisture from the exhaust gas, and the dried exhaust gas then enters an activated carbon plate where the activated carbon absorbs harmful substances, the treated exhaust gas is discharged through an exhaust pipe. Both the desiccant plate and the activated carbon plate have heating mesh plates installed on their bottom surfaces to heat the desiccant and activated carbon within their cavities, accelerating moisture evaporation and ensuring effective exhaust gas treatment, in actual use, the horizontal placement of the activated carbon plate and desiccant plate inside the intake pipe creates resistance to exhaust gas flow. Furthermore, dust in the exhaust gas easily adheres to the inner wall of the pipe, resulting in slow exhaust gas flow, reduced intake volume, and consequently, decreased exhaust gas treatment speed and efficiency.

[0005] Therefore, it is necessary to modify it to effectively prevent activated carbon plates and drying plates from blocking the flow of exhaust gas, accelerate the flow of exhaust gas, prevent dust contained in the exhaust gas from adhering to the inner wall of the pipe, and increase the intake volume, so as to speed up the exhaust gas treatment speed and improve the treatment efficiency. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a waste gas treatment device for chemical processing. This device effectively prevents activated carbon plates and drying plates from obstructing waste gas flow, accelerates waste gas flow, avoids dust in the waste gas adhering to the inner wall of the pipe, and increases the air intake, thereby accelerating waste gas treatment and improving treatment efficiency. It solves the problems caused by the horizontal placement of activated carbon plates and drying plates inside the inlet pipe, which creates resistance to waste gas flow. Simultaneously, dust in the waste gas easily adheres to the inner wall of the pipe, resulting in slow waste gas flow, reduced air intake, and consequently, decreased waste gas treatment speed and efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device for chemical processing, comprising a waste gas treatment tank, an exhaust pipe connected to the left side of the waste gas treatment tank, a filter pipe connected to the top of the waste gas treatment tank, a booster pipe connected to the top of the filter pipe, a treatment pipe connected to the top of the booster pipe, an inlet pipe connected to the top of the treatment pipe, a slot provided on the right side of the filter pipe, a sealing plate movably connected inside the slot, a filter element connected to the left side of the sealing plate by bolt thread, the left side of the filter element fitting against the left side of the inner wall of the filter pipe, a dual-head motor fixedly connected inside the booster pipe, a booster fan fixedly connected to the lower output end of the dual-head motor located above the filter element, the upper output end of the dual-head motor extending into the interior of the treatment pipe and fixedly connected to a shaft, an activated carbon plate fixedly connected to the left side of the shaft, a drying plate fixedly connected to the right side of the shaft, rubber brushes fixedly connected to the outer sides of both the activated carbon plate and the drying plate, the outer sides of the rubber brushes fitting against the inner wall of the treatment pipe.

[0008] As a preferred embodiment of this utility model, sealing strips are fixedly connected to all four sides of the sealing plate, and the surface of the sealing strips is in contact with the inner wall of the slot.

[0009] As a preferred embodiment of this utility model, the front and rear sides of the right side of the filter tube are rotatably connected to rotating rods located below the sealing plate, and a pressure plate is fixedly connected above the rotating rods, with the left side of the pressure plate fitting against the right side of the sealing plate.

[0010] As a preferred embodiment of this invention, a shroud located inside the booster tube is fixedly connected to the surface of the output end of the dual-head motor, and the bottom diameter of the shroud is larger than the top diameter.

[0011] As a preferred embodiment of this invention, semiconductor heating elements are fixedly connected to both the front and rear sides of the processing tube, and the heating end of the semiconductor heating element is in contact with the surface of the processing tube.

[0012] As a preferred embodiment of this invention, a filter screen is fixedly connected to the inside of the top end of the air intake pipe.

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

[0014] 1. This utility model uses a dual-head motor to drive the shaft and booster fan to rotate. The rotation of the shaft drives the activated carbon plate and drying plate to rotate inside the treatment tube to treat the waste gas. At the same time, the rotation of the activated carbon plate and drying plate drives the rubber brush to rotate and flush the inner wall of the treatment tube, preventing dust from adhering to the tube wall. The fan rotates and blows the waste gas inside the treatment tube towards the filter tube, creating a negative pressure inside the booster tube. This generates suction to draw the waste gas into the booster tube and blow it towards the filter tube. Then, the waste gas passes through the filter element and enters the waste gas treatment tank. This accelerates the flow rate of the waste gas, prevents dust in the waste gas from adhering to the inner wall of the pipe, increases the air intake, and thus speeds up the waste gas treatment and improves the treatment efficiency.

[0015] 2. By setting a sealing strip, this utility model seals the contact surface between the sealing plate and the slot, preventing exhaust gas from flowing out from the gap between the sealing plate and the slot, which would reduce the internal pressure of the booster tube and affect the boosting effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a waste gas treatment device for chemical processing, including a waste gas treatment tank 1. An exhaust pipe 2 is connected to the left side of the waste gas treatment tank 1. A filter pipe 3 is connected to the top of the waste gas treatment tank 1. A booster pipe 4 is connected to the top of the filter pipe 3. A treatment pipe 5 is connected to the top of the booster pipe 4. An inlet pipe 6 is connected to the top of the treatment pipe 5. A slot 7 is provided on the right side of the filter pipe 3. A sealing plate 8 is movably connected inside the slot 7. A filter element 9 is threadedly connected to the left side of the sealing plate 8 via bolts. The left side of the filter element 9 is connected to the filter pipe. The left side of the inner wall of the filter tube 4 is attached to the pressure tube 4. A dual-head motor 10 is fixedly connected inside the pressure tube 4. The lower output end of the dual-head motor 10 is fixedly connected to a pressure fan 11 located above the filter element 9. The upper output end of the dual-head motor 10 extends into the interior of the treatment tube 5 and is fixedly connected to a shaft 12. An activated carbon plate 13 is fixedly connected to the left side of the shaft 12, and a drying plate 14 is fixedly connected to the right side of the shaft 12. Rubber brushes 15 are fixedly connected to the outer sides of both the activated carbon plate 13 and the drying plate 14. The outer side of the rubber brushes 15 is attached to the inner wall of the treatment tube 5.

[0023] refer to Figure 4 Sealing strips 16 are fixedly connected around the perimeter of the sealing plate 8, and the surface of the sealing strips 16 is in contact with the inner wall of the slot 7.

[0024] As a technical optimization of this utility model, by setting a sealing strip 16, the contact surface between the sealing plate 8 and the slot 7 is sealed, preventing exhaust gas from flowing out from the gap between the contact surface between the sealing plate 8 and the slot 7, which would reduce the internal pressure of the booster pipe 4 and affect the boosting effect.

[0025] refer to Figure 4 The front and rear sides of the right side of the filter tube 3 are rotatably connected to rotating rods 17 located below the sealing plate 8. A pressure plate 18 is fixedly connected above the rotating rod 17, and the left side of the pressure plate 18 is in contact with the right side of the sealing plate 8.

[0026] As a technical optimization of this utility model, by setting the rotating rod 17 and the pressure plate 18, the sealing plate 8 is fixed, which prevents the sealing plate 8 from popping out of the slot 7 and affecting normal use. At the same time, the pressure plate 18 can be disengaged from the sealing plate 8 by rotating the rotating rod 17, so that the sealing plate 8 can be opened to clean or replace the filter element 9.

[0027] refer to Figure 3 A spoiler 19 located inside the booster tube 4 is fixedly connected to the surface of the output end of the dual-head motor 10. The bottom diameter of the spoiler 19 is larger than the top diameter.

[0028] As a technical optimization of this utility model, by setting up the baffle 19, the flow speed of the exhaust gas inside the booster pipe 4 is increased, and at the same time, it plays a certain protective role for the dual-head motor 10, avoiding damage to the dual-head motor 10 under the impact of exhaust gas for a long time, which would affect its normal use.

[0029] refer to Figure 2 Semiconductor heating elements 20 are fixedly connected to both the front and rear sides of the processing tube 5, and the heating end of the semiconductor heating element 20 is in contact with the surface of the processing tube 5.

[0030] As a technical optimization of this utility model, by setting a semiconductor heating element 20, the exhaust gas inside the treatment tube 5 can be heated, which can accelerate the reaction between the exhaust gas and the activated carbon plate 13 and the drying plate 14 and improve the exhaust gas treatment efficiency.

[0031] refer to Figure 1 A filter screen 21 is fixedly connected to the inside of the top of the air intake pipe 6.

[0032] As a technical optimization of this utility model, by setting up a filter screen 21, the waste gas that needs to be treated is filtered, thus preventing impurities contained in the waste gas from being sucked into the air inlet pipe 6 and affecting the normal use of the device.

[0033] The working principle and usage process of this utility model are as follows: During use, exhaust gas is sent into the treatment pipe 5 through the intake pipe 6. After the exhaust gas enters the treatment pipe 5, the dual-head motor 10 is started. The starting of the dual-head motor 10 drives the shaft 12 and the booster fan 11 to rotate. The rotation of the shaft 12 drives the activated carbon plate 13 and the drying plate 14 to rotate inside the treatment pipe 5 to treat the exhaust gas. At the same time, the rotation of the activated carbon plate 13 and the drying plate 14 drives the rubber brush 15 to rotate and flush the inner wall of the treatment pipe 5, preventing... Dust adheres to the pipe wall. The fan rotates and blows the exhaust gas inside the treatment pipe 5 towards the filter pipe 3, creating a negative pressure inside the booster pipe 4. This generates suction to draw the exhaust gas into the booster pipe 4 and blow it towards the filter pipe 3. The exhaust gas then passes through the filter element 9 and enters the exhaust gas treatment tank 1. After being treated by the exhaust gas treatment tank 1, the exhaust gas is discharged from the exhaust pipe 2. This accelerates the flow rate of the exhaust gas, prevents dust in the exhaust gas from adhering to the inner wall of the pipe, and increases the intake volume, thereby accelerating the exhaust gas treatment speed and improving treatment efficiency.
