Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a low-energy waste gas treatment device. Background Technology

[0002] Various pollutant gases, also known as waste gases, are generated during fuel combustion and production processes within a factory. If these waste gases are discharged directly without proper treatment, they will pollute the air. Moreover, these waste gases contain a large number of toxic substances, which can enter the human body through various respiratory pathways, thus causing harm to the human body. Some of these substances can even accumulate, further endangering human health. To save energy, a low-energy waste gas treatment device is usually used to treat the waste gases generated during production.

[0003] In low-energy waste gas treatment equipment, waste gas is fed into the tower from the bottom. The sprayed liquid comes into full contact with the waste gas, undergoing a neutralization reaction to adsorb acidic or alkaline pollutants contained in the waste gas. After purification, the waste gas is discharged from the gas outlet. The liquid is pressurized by a water pump at the bottom of the tower and sprayed down from the top of the tower through the connection pipe and the transfer pipe, and finally flows back to the bottom of the tower for recycling. The inner side of the tower is usually equipped with a filter plate, which filters out some impurities. However, the filter plate may be corroded by the liquid after long-term use, thus affecting the filtration effect. When replacing the filter plate, it is necessary to remove the filter plate, which requires stopping the low-energy waste gas treatment equipment, reducing the efficiency of the low-energy waste gas treatment equipment. Therefore, a low-energy waste gas treatment equipment is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-energy-consumption waste gas treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-energy waste gas treatment device includes a water washing tower, a waste gas inlet, and a purified gas outlet. A circulating water pump is installed on the outside of the water washing tower. One end of the circulating water pump is located inside the water washing tower and communicates with it. The other end of the circulating water pump is fixedly connected to a connecting pipe. A transfer pipe penetrating one side of the water washing tower is fixedly connected to one side of the connecting pipe. A spray head is installed at the bottom of the transfer pipe. A through pipe is fixedly connected to the other side of the connecting pipe. A dosing tank is located at the end of the through pipe away from the connecting pipe. A symmetrically arranged positioning plate is fixedly connected to the inner wall of the water washing tower. A filter plate is slidably connected to the top of the positioning plate. A symmetrically arranged connecting block is fixedly connected to both sides of the filter plate. A rotating rod is rotatably connected between a group of the connecting blocks. A spare plate is fixedly connected to the outside of the rotating rod by screws. A symmetrically arranged slot is opened on both sides of the water washing tower.

[0007] Preferably, the filter plate is engaged inside the slot, and there are two filter plates in total.

[0008] Preferably, the purified gas outlet is located at the top of the water washing tower and is connected to the water washing tower, and the exhaust gas inlet is located at the bottom of one side of the water washing tower and is connected to the water washing tower.

[0009] Preferably, the circulating water pump is connected to the connecting pipe, the connecting pipe is connected to the transfer pipe and the through pipe respectively, the transfer pipe is connected to the spray head, and the through pipe is connected to the dosing tank.

[0010] Preferably, a limit block is fixedly connected to the side of the spare plate away from the rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a structure consisting of a filter plate, connecting block, rotating rod, spare plate, and slot is used. When the filter plate is damaged and needs replacement, the spare plate, along with the rotating rod and connecting block, is rotated to keep the spare plate horizontal. Then, the spare plate is pushed towards the inside of the washing tower, causing it to act on the connecting block via the rotating rod, and then on the filter plate via the connecting block. This causes the filter plate to disengage from the slot. With the positioning plate in place, the filter plate can maintain stable movement. When the limiting block is in contact with the outer wall of the washing tower, the pushing of the spare plate stops, and the spare plate is locked inside the slot, replacing the filter plate. At this point, the filter plate is pushed to the outside of the washing tower, and the screws can be turned to disassemble the filter plate, along with the connecting block, rotating rod, and another spare plate. The filter plate can then be replaced, allowing for replacement of the filter plate without interrupting the use of the low-energy waste gas treatment equipment. Attached Figure Description

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A low-energy waste gas treatment device includes a water washing tower body 1, a waste gas inlet 2, and a purified gas outlet 3. A circulating water pump 4 is installed on the outside of the water washing tower body 1. One end of the circulating water pump 4 is located inside the water washing tower body 1 and communicates with the water washing tower body 1. The other end of the circulating water pump 4 is fixedly connected to a connecting pipe 13. A transfer pipe 14 that penetrates one side of the water washing tower body 1 is fixedly connected to one side of the connecting pipe 13. A spray head 15 is installed at the bottom of the transfer pipe 14. A through pipe 16 is fixedly connected to the other side of the connecting pipe 13. A dosing tank 5 is provided at the end of the through pipe 16 away from the connecting pipe 13. A positioning plate 6 arranged symmetrically is fixedly connected to the inner wall of the water washing tower body 1. A filter plate 7 is slidably connected to the top of the positioning plate 6. A connecting block 8 arranged symmetrically is fixedly connected to both sides of the filter plate 7. A rotating rod 9 is rotatably connected between a group of connecting blocks 8. A spare plate 10 is fixedly connected to the outside of the rotating rod 9 by screws. A slot 12 arranged symmetrically is opened on both sides of the water washing tower body 1.

[0027] The filter plate 7 is engaged inside the slot 12. There are two filter plates 7 in total. This arrangement allows the filter plates 7 to be detached from the water washing tower 1 and allows for multiple filtrations of the exhaust gas. The purified gas outlet 3 is located at the top of the water washing tower 1 and is connected to the water washing tower 1. The exhaust gas inlet 2 is located at the bottom of one side of the water washing tower 1 and is connected to the water washing tower 1. This arrangement allows the exhaust gas to enter the water washing tower 1 from the exhaust gas inlet 2 and exit the water washing tower 1 from the purified gas outlet 3. The circulating water pump 4 is connected to the connecting pipe 13. The connecting pipe 13 is connected to the transfer pipe 14 and the through pipe 16 respectively. The transfer pipe 14 is connected to the spray head 15, and the through pipe 16 is connected to the dosing tank 5. This arrangement allows the dosing tank 5 and the liquid at the bottom of the water washing tower 1 to be recycled. The spare plate 10 is fixedly connected to the side away from the rotating rod 9 by the limiting block 11. This arrangement allows the spare plate 10 to be positioned by the limiting block 11, making it easy to remove the spare plate 10.

[0028] Workflow: In this utility model, all electrical appliances are equipped with an external power supply or a built-in battery. Exhaust gas enters the washing tower 1 through the exhaust gas inlet 2. The circulating water pump 4 draws the chemical solution from the inside of the dosing tank 5 through the connecting pipe 16. The chemical solution flows along the connecting pipe 16 to the connecting pipe 13, and then from the connecting pipe 13 to the transfer pipe 14. The chemical solution is sprayed out from the spray head 15 connected to the transfer pipe 14. The chemical solution fully contacts the exhaust gas, undergoing a neutralization reaction to adsorb the acidic or alkaline pollutants contained in the exhaust gas. After purification, the exhaust gas is discharged from the washing tower 1 through the purified gas outlet 3, while the chemical solution falls to the bottom of the washing tower 1 and is drawn by the circulating water pump 4 for a new round of washing. When the exhaust gas rises to the purified gas outlet 3, it passes through the filter plate 7. The filter plate 7 may be damaged after prolonged immersion in the chemical solution. The spare plate 10, along with the rotating rod 9 and the connecting block 8, is rotated to... Keep the spare plate 10 horizontal, then push the spare plate 10 towards the inside of the washing tower body 1. This causes the spare plate 10 to act on the connecting block 8 through the rotating rod 9, and then on the filter plate 7 through the connecting block 8. This causes the filter plate 7 to disengage from the slot 12. Under the positioning of the positioning plate 6, the filter plate 7 can maintain stable movement. When the limiting block 11 is in contact with the outer wall of the washing tower body 1, stop pushing the spare plate 10. The spare plate 10 is then engaged inside the slot 12, replacing the filter plate 7. At this time, the filter plate 7 is pushed to the outside of the washing tower body 1. Then, rotate the screw to disassemble the filter plate 7 along with the connecting block 8, the rotating rod 9, and another spare plate 10. Then replace the filter plate 7. Then, reverse the operation to install the filter plate 7 and the spare plate 10 engaged inside the slot 12. That is, the filter plate 7 can be replaced without delaying the use of the low-energy waste gas treatment equipment.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
