Description

Technical Field

[0001] This utility model relates to the field of waste gas filtration technology, specifically a waste gas pollution filtration device. Background Technology

[0002] With industrial development, a large amount of waste gas is generally emitted. However, if the waste is discharged directly without treatment, the toxic substances in the waste gas can easily affect the surrounding environment and even affect people's health if they breathe in the waste gas.

[0003] For example, the announcement number CN218107072U is named an environmental protection and pollution prevention waste gas filtration and emission device. The device includes a filter bottom cylinder, a fixed circular frame and supporting columns. The fixed circular frame is fixedly connected to the upper outer side of the filter bottom cylinder. Four supporting columns are fixedly connected to the outer side of the fixed circular frame at even intervals along the circumference. The air inlet pipe is connected to the exhaust pipe, so the waste gas can be discharged into the filter bottom cylinder through the air inlet pipe. The filter screen plate filters the toxic substances in the waste gas. The waste gas with the toxic substances filtered is then discharged through the air outlet bottom frame.

[0004] When the above-mentioned device is in use, the exhaust gas will come into direct contact with the filtration mechanism. Since the exhaust gas temperature is usually high and contains particulate matter, the direct contact between the exhaust gas and the filtration mechanism will cause blockage and damage of the particulate matter, thereby reducing the filtration effect of the exhaust gas. Therefore, we propose an exhaust gas pollution filtration device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an exhaust gas pollution filtration device to solve the problem mentioned in the background art that exhaust gas comes into direct contact with the filtration mechanism. Since the exhaust gas temperature is usually high and contains particulate matter, direct contact between the exhaust gas and the filtration mechanism will cause blockage and damage of the particulate matter, thereby reducing the filtration effect of the exhaust gas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas pollution filtration device, including a filter box;

[0007] Also includes:

[0008] An air intake pipe is installed above the filter box. An exhaust pipe is installed on one side of the lower half of the filter box. The filter box is internally divided into a pretreatment chamber and a filtration chamber. The pretreatment chamber is located at the upper part of the filter box, and the filtration chamber is located at the lower part of the filter box. One end of the air intake pipe extends to the lower part of the pretreatment chamber, and the exhaust pipe connects to the interior of the filtration chamber. A transmission pipe is installed on the outer side of the filter box. One end of the transmission pipe connects to the interior of the pretreatment chamber, and the other end extends to the bottom of the interior of the filtration chamber. A spraying mechanism is installed inside the pretreatment chamber, and a filtration mechanism is installed inside the filtration chamber.

[0009] Preferably, the spraying mechanism consists of a fixed frame and nozzles. The fixed frame has a cross-shaped structure and is located in the upper middle layer inside the pretreatment chamber. Several nozzles are provided and evenly distributed at the bottom of the fixed frame. A bracket is installed on the outside of the filter box. A water tank is installed on the upper end of the bracket. A conveying pipe is installed on the upper end of the fixed frame. The pipe at the bottom of the conveying pipe passes through the fixed frame and connects to the nozzles. One end of the conveying pipe extends out of the outside of the filter box and connects to the water pump inside the water tank.

[0010] Preferably, the filtration mechanism consists of a collar and a filter element. The collar is slidably engaged with one end surface of the transmission tube located inside the filtration chamber, and the filter element is fixed to the bottom of the collar and is sleeved on the outside of the transmission tube. The end surface of the transmission tube sleeved inside the filter element has through holes evenly distributed.

[0011] Preferably, the bottom of the filter box is integrally formed with a round hole, and the bottom of the filter element is mounted with a base plate, and the base plate and the round hole are threaded together.

[0012] Preferably, a drain pipe is provided on the outer side of the filter box, and the drain pipe extends into the interior of the pretreatment chamber, and a solenoid valve is installed at the upper end of the drain pipe.

[0013] Preferably, a water immersion sensor is installed on one side of the pretreatment chamber, and the output end of the water immersion sensor is electrically connected to the input end of the solenoid valve.

[0014] Preferably, the water immersion sensor is equipped with a protective cover, and the bottom of the protective cover is open.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By dividing the interior of the filter box into a pretreatment chamber and a filter chamber, the exhaust gas is transported to the pretreatment chamber through the air inlet pipe. The spray mechanism inside the pretreatment chamber removes and separates the particulate matter in the exhaust gas. At the same time, it can cool the exhaust gas and neutralize acidic gases, preventing the filter bag from being blocked and damaged due to excessive temperature or the presence of particulate matter.

[0017] (2) By installing a transmission pipe on the outside of the filter box, the two ends of the transmission pipe are connected to the pretreatment chamber and the filter chamber respectively. The air inlet of the transmission pipe is located above the pretreatment chamber, while the air outlet of the air inlet pipe is located inside the lower part of the pretreatment chamber. This allows the exhaust gas to float upward from the air outlet of the air inlet pipe and be pretreated by the spraying mechanism. Then, the exhaust gas enters from the air inlet of the transmission pipe, while the air outlet of the transmission pipe extends to the bottom of the filter chamber. Through holes are set around the air outlet to facilitate uniform exhaust. A filter element is fitted around the through holes. The filter element further filters the exhaust gas to meet the standard and is discharged from the exhaust pipe. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides an exhaust gas pollution filtration device, which includes a filter box 1. The main problem addressed by this utility model is that exhaust gas comes into direct contact with the filtration mechanism. Since exhaust gas is typically at a high temperature and contains particulate matter, this direct contact can lead to blockage and damage from these particles, thus reducing the effectiveness of the filtration.

[0025] An intake pipe 2 is installed above the filter box 1. An exhaust pipe 5 is installed on one side of the lower half of the filter box 1. The filter box 1 is divided into a pretreatment chamber 19 and a filter chamber 20. The pretreatment chamber 19 is located at the upper part of the filter box 1, and the filter chamber 20 is located at the lower part of the filter box 1. One end of the intake pipe 2 extends to the lower part of the pretreatment chamber 19, and the exhaust pipe 5 connects to the interior of the filter chamber 20. A transmission pipe 8 is installed on the outer side of the filter box 1. One end of the transmission pipe 8 connects to the interior of the pretreatment chamber 19, and the other end of the transmission pipe 8 extends to the bottom of the interior of the filter chamber 20. A spray mechanism 22 is installed inside the pretreatment chamber 19, and a filter mechanism 21 is installed inside the filter chamber 20.

[0026] For the device provided by this utility model, please refer to Figure 1-4 The following is a detailed introduction.

[0027] To further explain, the spraying mechanism 22 consists of a fixed frame 13 and nozzles 12. The fixed frame 13 has a cross-shaped structure and is located in the upper middle layer inside the pretreatment chamber 19. Several nozzles 12 are provided and evenly distributed at the bottom of the fixed frame 13. A bracket 4 is installed on the outside of the filter box 1. A water tank 3 is installed on the upper end of the bracket 4. A conveying pipe 9 is installed on the upper end of the fixed frame 13. The pipe at the bottom of the conveying pipe 9 passes through the fixed frame 13 and connects to the nozzles 12. One end of the conveying pipe 9 extends out of the outside of the filter box 1 and connects to the water pump inside the water tank 3. The medicine is poured into the water tank 3, and the water pump in the water tank 3 uses the conveying pipe 9 to transport the medicine to the nozzles 12 for spraying. This can pre-treat the exhaust gas and separate larger particles.

[0028] To further explain, the filtration mechanism 21 consists of a collar 16 and a filter element 15. The collar 16 is slidably engaged with one end surface of the transmission pipe 8 located inside the filtration chamber 20, and the filter element 15 is fixed to the bottom of the collar 16 and sleeved on the outside of the transmission pipe 8. The end surface of the transmission pipe 8 sleeved inside the filter element 15 has through holes 14 evenly distributed. The bottom of the filter box 1 is integrally formed with a round hole 11. A base plate 10 is installed at the bottom of the filter element 15, and the base plate 10 is threadedly connected to the round hole 11. The filter element 15 can be removed from the inside of the filtration chamber 20 by rotating the base plate 10, and the filter element 15 is fixed to the other end of the transmission pipe 8 by the collar 16, which allows for quick disassembly and replacement.

[0029] To further explain, a drain pipe 6 is provided on the outer side of the filter box 1, and the drain pipe 6 extends into the interior of the pretreatment chamber 19. A solenoid valve 7 is installed at the upper end of the drain pipe 6. A water immersion sensor 18 is installed on the inner side of the pretreatment chamber 19, and the output end of the water immersion sensor 18 is electrically connected to the input end of the solenoid valve 7. A protective cover 17 is installed on the outside of the water immersion sensor 18, and the bottom of the protective cover 17 is open. The sprayed liquid accumulates at the bottom of the interior of the pretreatment chamber. When the liquid containing particulate matter accumulates to a high level, it will enter from the bottom of the protective cover 17 and come into contact with the water immersion sensor 18. At this time, the solenoid valve 7 will be activated, causing the drain pipe 6 to open and the liquid to flow out. The protective cover 17 can protect the outside of the water immersion sensor 18, thereby preventing the sprayed liquid from coming into contact with the water immersion sensor 18.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
