Description

Technical Field

[0001] This utility model relates to the field of waste gas recovery technology, and in particular to an integrated waste gas recovery and purification device. Background Technology

[0002] In industrial production and daily life, large amounts of waste gas are continuously emitted, posing a serious threat to the ecological environment and human health. With the continuous enhancement of environmental awareness and the increasingly stringent relevant regulations, the development of efficient waste gas recovery and purification devices has become an urgent task. Such integrated devices can effectively reduce harmful substances in waste gas and realize resource recycling, which is of great significance to sustainable development and has therefore received widespread attention and in-depth research.

[0003] Currently, in the field of waste gas treatment technology, common methods include simple filtration, which uses specific filter materials to intercept particles and impurities in waste gas, and adsorption, which uses adsorbents such as activated carbon to adsorb harmful components in waste gas. Filtration often uses a simple filter screen structure, relying on physical barriers to retain pollutants on the filter screen. Adsorption is based on the porous structure of the adsorbent, using intermolecular forces to adsorb target substances in waste gas. These technologies can treat waste gas to a certain extent, but as the composition of waste gas becomes increasingly complex, the difficulty of treatment continues to increase.

[0004] However, traditional waste gas treatment methods have obvious drawbacks. Because waste gas is directly filtered, a large amount of particulate matter and impurities tend to accumulate quickly on the filtration device, causing frequent clogging. This not only increases the cost and frequency of equipment maintenance but also seriously affects the efficiency of waste gas treatment. At the same time, simple filtration and adsorption methods are insufficient to thoroughly purify waste gas with complex components, resulting in a large amount of substandard waste gas being discharged into the environment, causing continuous damage to air quality and failing to meet current stringent environmental protection requirements. Therefore, an integrated waste gas recovery and purification device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated waste gas recovery and purification device, which aims to improve the problems of direct filtration of waste gas in the prior art, which leads to clogging of the filtration device and incomplete filtration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated waste gas recovery and purification device includes a storage tank. Connecting pipes are fixedly connected to both sides of the outer wall of the storage tank. The left connecting pipe is located at the bottom of the storage tank, and the right connecting pipe is located at the top of the storage tank. A diversion box is fixedly connected to one end of the left connecting pipe. An air inlet pipe is fixedly connected to one side wall of the diversion box. A purification box is fixedly connected to one end of the right connecting pipe. A reflux component is provided on the side wall of the purification box.

[0008] The return flow assembly includes a second diversion box. The side wall of the second diversion box is fixedly connected to the side wall of the purification box through the connecting pipe. A return flow pipe is fixedly connected to the top of the second diversion box. The other end of the second diversion box is fixedly connected to the top of the first diversion box. An exhaust pipe is fixedly connected to the side wall of the second diversion box.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The purification chamber is equipped with a support platform inside, and the outer wall of the support platform is fixedly connected to the inner wall of the purification chamber.

[0013] As a further description of the above technical solution:

[0014] The support platform is equipped with multiple filter plates arranged in an array, and the outer wall of each filter plate is slidably connected to the inside of the filter plate.

[0015] As a further description of the above technical solution:

[0016] Each filter element plate is provided with a handle on its side wall, and the handle side wall is fixedly connected to the side wall of the filter element plate. The handle is located on the outer wall of the support platform.

[0017] As a further description of the above technical solution:

[0018] Each of the filter plates has a locking block on its other side wall. The locking block is fixedly connected to the side wall of the filter plate and is located inside the handle.

[0019] As a further description of the above technical solution:

[0020] Each locking block has a fixing box on its side. The outer wall of the fixing box is fixedly connected to the inside of the handle. The fixing box contains symmetrical upper and lower limiting beads. The outer wall of the limiting beads is slidably connected to the inner wall of the fixing box.

[0021] As a further description of the above technical solution:

[0022] Each of the limiting beads is provided with a return spring on its sidewall. One end of each return spring is fixedly connected to the inside of the fixing box, and the other end of each return spring is fixedly connected to the sidewall of the limiting bead.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the exhaust gas first enters the storage tank through the first distribution box. The purification liquid in the storage tank adsorbs and precipitates the particulate matter in the exhaust gas. Then, the exhaust gas enters the purification box through the top pipe of the storage tank for further adsorption of harmful substances. Subsequently, the exhaust gas enters the second distribution box. After being detected by the inspection sensor, if it is qualified, it is discharged through the exhaust pipe. If it is unqualified, it returns to the first distribution box through the return pipe for purification again.

After the new filter plate is inserted, its side wall locking block is inserted into the fixing box. The front end squeezes the limiting bead, which compresses the return spring. When the locking block is inserted to the bottom, the return spring pushes the limiting bead into the recessed area of ​​the side wall of the locking block to achieve locking. This achieves the effect of quickly replacing the filter plate, solves the problem of cumbersome replacement of traditional filter plates, improves the efficiency of filter plate replacement, and ensures the continuous and efficient operation of the device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Reference Figure 1 This utility model provides an embodiment of an integrated waste gas recovery and purification device, comprising a storage tank 1 made of corrosion-resistant stainless steel, capable of effectively storing liquid for purifying waste gas. The storage tank 1 contains the purification liquid, which, through contact with the waste gas, adsorbs and precipitates particulate matter in the waste gas, thus initially purifying it. Connecting pipes 5 are fixedly connected to both sides of the outer wall of the storage tank 1. The connecting pipes 5 are made of a corrosion-resistant material similar to that of the storage tank 1 and are used to transfer waste gas between components. The left connecting pipe 5 is located at the bottom of the storage tank 1 and its function is to introduce waste gas from the diversion box 2 into the storage tank 1. The right connecting pipe 5 is located at the top of the storage tank 1 and its function is to transfer the waste gas that has passed through the storage tank 1 after initial purification. The purified exhaust gas is transported to the purification box 6. One end of the left connecting pipe 5 is fixedly connected to the diversion box 2. The function of the diversion box 2 is to perform preliminary diversion and distribution of the exhaust gas entering from the inlet pipe 4. The flow direction of the exhaust gas is controlled by the internal valve, and the exhaust gas is discharged into the storage tank 1 in an orderly manner. The inlet pipe 4 is fixedly connected to the side wall of the diversion box 2, which is used to introduce the exhaust gas to be treated into the interior of the diversion box 2. It is the inlet channel for the exhaust gas to enter the entire purification device. One end of the right connecting pipe 5 is fixedly connected to the purification box 6, which is used to further purify the exhaust gas after the preliminary treatment in the storage tank 1. The side wall of the purification box 6 is equipped with a return component. The return component is used to detect the purified exhaust gas and determine the flow direction of the exhaust gas based on the detection results.

[0034] The return flow assembly includes a second diversion box 7, which receives the purified exhaust gas from the purification box 6. It contains valves and an exhaust gas detector. The side wall of the second diversion box 7 is fixedly connected to the side wall of the purification box 6 via a connecting pipe 5. A return flow pipe 3 is fixedly connected to the top of the second diversion box 7. Its function is to return the exhaust gas to the first diversion box 2 when the exhaust gas fails the test, allowing it to re-enter the purification process. The other end of the second diversion box 7 is fixedly connected to the top of the first diversion box 2, forming a passage for exhaust gas return. An exhaust pipe 8 is fixedly connected to the side wall of the second diversion box 7 for discharging qualified exhaust gas into the external environment. In the purification chamber 6, a door 11 is provided on the side wall. The purpose of the door 11 is to facilitate the maintenance, replacement and inspection of the filter plate 13 and other components inside the purification chamber 6 by the staff. The side wall of the door 11 is rotatably connected to the inside of the purification chamber 6. A control valve 10 is fixedly connected to the bottom of the purification chamber 6 to control whether the hot air generated by the heating box 9 enters the purification chamber 6. The bottom of the control valve 10 is fixedly connected to the heating box 9, which is equipped with a heating element to generate hot air to catalytically treat the saturated filter plate 13 inside the purification chamber 6, so as to regenerate the filter plate 13.

[0035] Specifically, when using this integrated waste gas recovery and purification device, the waste gas generated in industrial production first flows in a straight line from the waste gas discharge port of the industrial production equipment along the inlet pipe 4 under the action of pressure difference in the pipeline, towards the distribution box 2. The inlet pipe 4 guides the waste gas into the distribution box 2. After the waste gas enters the distribution box 2, the valve inside the distribution box 2 opens under the command of the equipment control system. Under the action of pressure difference, the waste gas in the distribution box 2 flows through the connecting pipe... 5. The exhaust gas is discharged into the storage tank 1. After entering the storage tank 1, the exhaust gas comes into contact with the purification liquid inside the storage tank 1. Under the action of gravity and the adsorption force of the purification liquid, the particulate matter in the exhaust gas gradually settles to the bottom of the storage tank 1. Subsequently, the exhaust gas, which has undergone preliminary purification and has had particulate matter removed, flows from the top of the storage tank 1 along the top pipe towards the purification box 6. After entering the purification box 6, the exhaust gas comes into contact with multiple filter plates 13 inside the purification box 6. The filter plates 13 further purify the harmful substances in the exhaust gas. Adsorption: Harmful substances in the exhaust gas are intercepted and adsorbed by the filter plate 13, thereby achieving deeper purification of the exhaust gas. Subsequently, the exhaust gas purified by the filter plate 13 flows from the inside of the purification box 6 along the side wall pipe to the direction of the diversion box 7 under the action of the pressure difference in the purification box 6. After the exhaust gas enters the diversion box 7, the inspection sensor inside the diversion box 7 begins to detect the exhaust gas. The inspection sensor detects and analyzes various pollutant indicators in the exhaust gas according to the preset detection standards. If the detection is qualified, the exhaust gas is discharged through the exhaust pipe 8 under the action of the pressure difference in the diversion box 7. If the detection is unqualified, the exhaust gas flows from the inside of the diversion box 7 along the return pipe 3 to the direction of the diversion box 2 under the action of the valve in the diversion box 7, and re-enters the purification process. Through such cyclic treatment, the effect of efficient treatment of exhaust gas is achieved. When the filter plate 13 inside the purification box 6 is saturated, the equipment control system issues a command to start the heating box 9. When the heating element inside the heating chamber 9 is powered on, it converts electrical energy into heat energy, raising the air temperature inside the heating chamber 9 and generating hot air. The control valve 10 at the bottom of the purification chamber 6 opens under the command of the equipment control system. Once the control valve 10 is open, the hot air inside the heating chamber 9, under the influence of pressure difference, is discharged into the purification chamber 6 through the control valve 10. After entering the purification chamber 6, the hot air diffuses within the chamber and comes into contact with the filter plate 13. The hot air catalyzes the filter plate 13. Under the influence of the hot air, the organic matter inside the filter plate 13 absorbs heat, its molecular motion intensifies, and it gradually volatilizes. Simultaneously, during the catalytic process, the activated carbon inside the filter plate 13 undergoes internal structural changes as it absorbs heat and the organic matter volatilizes, releasing energy and regenerating the activated carbon, restoring its adsorption capacity. This regeneration process extends the service life of the filter plate 13 and reduces equipment operating costs.

[0036] Reference Figure 2 - Figure 4 The purification chamber 6 is equipped with a support platform 12 made of stainless steel, which has high strength and corrosion resistance. This platform stably supports multiple filter plates 13 within the purification chamber 6. The outer wall of the support platform 12 is fixedly connected to the inner wall of the purification chamber 6, providing a platform for the installation and placement of the filter plates 13. Multiple filter plates 13 are installed inside the support platform 12. These filter plates 13 are made of activated carbon fiber, which has a large specific surface area and good adsorption performance, effectively adsorbing harmful substances in the exhaust gas. The filter plates 13 are arranged in an array. The outer wall of plate 13 is slidably connected to the interior of filter plate 13. Each side wall of filter plate 13 is equipped with a handle 14, made of aluminum alloy. The handle 14 provides a point of leverage for the operator. The side walls of the handles 14 are fixedly connected to the side walls of filter plate 13. All handles 14 are located on the outer wall of the support platform 12. Each other side wall of filter plate 13 is equipped with a locking block 15, made of metal. The locking block 15 cooperates with the fixing box 16 to fix and unlock the filter plate 13 within the support platform 12. The side walls of the locking blocks 15 are fixedly connected to the filter plate. 13. The locking block 15 is located inside the handle 14. Each side of the locking block 15 is equipped with a fixing box 16 to accommodate components such as the limiting bead 18 and the return spring 17, providing installation space for these components. The outer wall of the fixing box 16 is fixedly connected to the inside of the handle 14. The fixing box 16 contains symmetrically arranged limiting beads 18. The function of the limiting beads 18 is to engage with the recessed area of ​​the side wall of the locking block 15 when the locking block 15 is inserted into the fixing box 16, fixing the locking block 15 within the fixing box 16. The outer wall of the limiting beads 18 is slidably connected to the inner wall of the fixing box 16. Each of the 18 side walls is provided with a return spring 17. The function of the return spring 17 is to provide elastic force to the limiting bead 18 when the locking block 15 is inserted into the fixing box 16. When the locking block 15 squeezes the limiting bead 18, the return spring 17 is compressed and stores elastic potential energy. When the locking block 15 is inserted into place, the return spring 17 releases elastic potential energy and pushes the limiting bead 18 into the recessed area of ​​the side wall of the locking block 15, thereby locking the filter plate 13. One end of the return spring 17 is fixedly connected to the inside of the fixing box 16, and the other end of the return spring 17 is fixedly connected to the side wall of the limiting bead 18.

[0037] Specifically, when filter plate 13 reaches the end of its service life and needs to be replaced, the staff first opens the door 11 on the side wall of the purification chamber 6. The staff locates the handle 14 on the side wall of the filter plate 13 that needs to be replaced, grasps the handle 14, and pulls the filter plate 13 outward. Under the pulling force applied by the staff, the filter plate 13 moves linearly outward along its sliding track inside the support platform 12. The displacement of the filter plate 13 causes the locking block 15 to also move outward. As the filter plate 13 moves outward, the locking block 15 gradually disengages from the locking state of the limiting bead 18, thus completing the unlocking. The operator continues to pull the filter plate 13, completely removing it from the support platform 12. The operator aligns the new filter plate 13 with the slot in the support platform 12 and pushes the new filter plate 13 into the support platform 12, causing the locking block 15 on the side wall of the filter plate 13 to also be inserted into the fixing box 16. During the insertion of the locking block 15 into the fixing box 16, the front end of the locking block 15 squeezes the limiting beads 18 on both sides. Under the squeezing force at the front end of the locking block 15, the limiting bead 18 moves linearly towards both sides inside the fixing box 16. The displacement of the limiting bead 18 causes the return spring 17 to be compressed. When the locking block 15 is inserted to the bottom, the recessed area on the side wall of the locking block 15 moves to the position opposite to the limiting bead 18. At this time, the return spring 17 releases the elastic potential energy stored before, pushing the limiting bead 18 to be inserted into the recessed area on the side wall of the locking block 15, thereby completing the locking and achieving the effect of quickly replacing the filter plate 13.

[0038] Working principle: When using this integrated waste gas recovery and purification device, the waste gas is first discharged into the interior of the first distribution box 2 through the inlet pipe 4. Then, the valve inside the first distribution box 2 is opened, and the waste gas is discharged into the storage tank 1 through the connecting pipe 5. The purification liquid inside the storage tank 1 adsorbs and precipitates the particulate matter in the waste gas. Then, the waste gas is discharged into the purification box 6 through the pipe at the top of the storage tank 1. Multiple filter plates 13 inside the purification box 6 further purify and adsorb harmful substances in the waste gas. Then, it is discharged into the second distribution box 7 through the pipe on the side wall of the purification box 6. The detection sensor inside the second distribution box 7 detects the waste gas. If the detection is qualified, it is discharged through the exhaust pipe 8. If the detection is unqualified, it is discharged into the interior of the first distribution box 2 through the return pipe 3 and enters the purification process again, thereby achieving the effect of efficient waste gas treatment.

[0039] When the filter plate 13 inside the purification chamber 6 becomes saturated with adsorption, the heating chamber 9 at the bottom of the purification chamber 6 starts to work, generating hot air that is discharged into the purification chamber 6 through the control valve 10. This catalyzes the filter plate 13, causing the organic matter inside the filter plate 13 to volatilize and releasing energy to regenerate the activated carbon inside the filter plate 13. When the filter plate 13 reaches the end of its service life and needs to be replaced, the operator pulls the handle 14, causing the filter plate 13 to move outward. The movement of the filter plate 13 causes the locking block 15 to move outward as well, disengaging the locking block 15 from the fixing box 16, thus unlocking it. After the new filter plate 13 is inserted into the support platform 12, the locking block 15 on its side wall inserts into the fixing box 16. The front end of the locking block 15 presses against the limit beads 18 on both sides, causing the limit beads 18 to press against the return spring 17. When the locking block 15 is fully inserted, the return spring 17 pushes the limit beads 18 into the recessed area on the side wall of the locking block 15, thus locking it in place. This achieves the effect of quickly replacing the filter plate 13.
