Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically relating to a multi-stage spray VOCs treatment automatic system. Background Technology

[0003] VOCs, as an important component of waste gas, refer to organic compounds that have high saturated vapor pressure, low boiling point, small molecular weight under standard conditions, and are easily volatilized at room temperature. Furthermore, volatile organic compounds are important precursors to secondary pollutants such as fine particulate matter and ozone, thereby contributing to atmospheric environmental problems such as haze and photochemical smog.

[0005] Current multi-stage spray VOCs treatment automated systems often encounter blockages in the inlet pipes due to the large number of fixed particles in the exhaust gas. These blockages require manual cleaning and unclogging, making the process cumbersome and increasing labor intensity. Therefore, there is an urgent need for a multi-stage spray VOCs treatment automated system.

[0006] A patent with publication number CN118179214A discloses a tail gas absorption device based on a multi-stage spray system. The device includes a first pipe, a fixed cylinder, semi-rings, a second electric telescopic rod, a fourth telescopic rod, a motor, and a rotating column. To clean impurities clogging the first pipe, the fixed cylinder is inserted between the two semi-rings by holding the handle. The second electric telescopic rod is then activated, causing the two semi-rings to move closer together, thus limiting the position of the fixed cylinder. Subsequently, the fourth telescopic rod is activated, pushing the rotating column into the first pipe. As the fourth telescopic rod extends, the rotating column discharges the impurities from the outlet of the first pipe. During this process, the motor is activated, and its output shaft drives the rotating column to rotate, thereby cleaning the inner wall of the first pipe using a scraper and rubber rod.

[0007] However, when cleaning the impurity particles blocking the first pipe, the above solution not only requires inserting the rotating column into the first pipe, but also requires setting up a second electric telescopic rod, a fourth telescopic rod, and multiple drive sources such as motors. The overall structure is complex and the operation is cumbersome. In addition, the need to set up many drive sources in the process not only increases the production and maintenance costs, but also increases the difficulty of constructing the control system, making it inconvenient for actual production use.

[0008] To address the aforementioned problems, this invention proposes a multi-stage spray VOCs treatment automatic system. Summary of the Invention

[0009] To address the problems existing in the background art, the present invention provides a multi-stage spray VOCs treatment automatic system.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] An automated multi-stage spray VOCs treatment system includes a purification tower. The bottom of the purification tower is fixedly connected to two air inlet pipes via a collecting pipe. These two air inlet pipes are a first air inlet pipe and a second air inlet pipe. The first and second air inlet pipes are symmetrically arranged and both are connected to a waste gas conveying assembly. A support rod is fixedly installed between the first and second air inlet pipes. A first baffle and a second baffle are slidably mounted on the support rod at their upper limits. The first and second baffles are fixedly connected by a connecting rod. The first baffle and the second baffle are slidably engaged with each other. Two rubber cones are fixedly installed on the support rod, symmetrically arranged, with each of the first and second baffles corresponding to one of the rubber cones. By engaging the rubber cones with the corresponding first or second baffle, the system can automatically switch the air inlet pipes and clear any blockages in the air inlet pipes.

[0012] Furthermore, the exhaust gas conveying assembly includes a main intake pipe, one end of which is fixedly connected to a diversion pipe, which is connected to both the first intake pipe and the second intake pipe.

[0013] Furthermore, both the first baffle and the second baffle are provided with a first through hole for the support rod to pass through.

[0014] Furthermore, a first airbag and a second airbag are fixedly installed on opposite sides of the first baffle and the second baffle, respectively. A fixed shell is fixedly installed inside both the first and second air intake pipes, and a contraction airbag is fixedly installed on each fixed shell. The first airbag is fixedly connected to the fixed shell inside the first air intake pipe and communicates with the contraction airbag inside the first air intake pipe through an air hole. The second airbag is fixedly connected to the fixed shell inside the second air intake pipe and communicates with the contraction airbag inside the second air intake pipe through an air hole.

[0015] Furthermore, limit rods are fixedly provided on the opposing sides of the two fixed shells, and a second through hole for the limit rods to pass through is provided on both the first baffle and the second baffle.

[0016] Furthermore, an exhaust pipe is fixedly installed at the top of the purification tower, and a drain pipe is fixedly installed at the bottom of the purification tower.

[0017] Furthermore, two sets of spray pipes are fixedly installed inside the purification tower, and an inlet pipe is fixedly installed outside the purification tower. The output end of the inlet pipe is connected to the two sets of spray pipes, and the input end of the inlet pipe is connected to the external spray box.

[0018] Furthermore, the purification tower is internally fixed with two sets of support rings, each set of support rings can be detachably equipped with a packing absorption layer, and a sealing door can be detachably installed on the outer surface of the purification tower at the position corresponding to the packing absorption layer.

[0019] This application has the following beneficial effects:

[0020] This application uses a rubber cone in conjunction with a corresponding first or second baffle to enable the system to automatically switch the intake pipe and clear any blockages in the intake pipe. This avoids the complex operation of manually switching and clearing the pipe when it is blocked. The structure is simple and does not require an additional drive source, thereby reducing production and maintenance costs while lowering the construction difficulty of the control system, making it more suitable for actual production use.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-9 As shown, the technical solution adopted by the present invention is as follows: a multi-stage spray VOCs treatment automatic system includes a purification tower 1, a collection pipe 2 is fixedly connected to the bottom of the purification tower 1, and two air inlet pipes are fixedly connected to the collection pipe 2, namely a first air inlet pipe 3 and a second air inlet pipe 4; the first air inlet pipe 3 and the second air inlet pipe 4 are symmetrically arranged on the collection pipe 2, and both the first air inlet pipe 3 and the second air inlet pipe 4 are connected to the waste gas conveying component.

[0035] The exhaust gas conveying assembly includes a main intake pipe 51, one end of which is fixedly connected to a diversion pipe 5. The diversion pipe 5 is connected to both the first intake pipe 3 and the second intake pipe 4. External exhaust gas enters the diversion pipe 5 through the main intake pipe 51 and then enters the first intake pipe 3 and the second intake pipe 4 through the diversion pipe 5.

[0036] A support rod 13 is fixedly installed between the first air intake pipe 3 and the second air intake pipe 4. The support rod 13 has a first baffle 14 and a second baffle 15 slidably installed at its upper limit. The first baffle 14 and the second baffle 15 are fixedly connected by a connecting rod 25. The first baffle 14 is adapted to the first air intake pipe 3 and the two slide together. The second baffle 15 is adapted to the second air intake pipe 4 and the two slide together.

[0037] Furthermore, both the first baffle 14 and the second baffle 15 are provided with a first through hole 16 for the support rod 13 to pass through.

[0038] In addition, two rubber cones 17 are fixedly installed on the support rod 13. The two rubber cones 17 are symmetrically arranged, and the first baffle 14 and the second baffle 15 correspond to one rubber cone 17 respectively.

[0039] By cooperating with the corresponding first baffle 14 or second baffle 15, the system can automatically switch the intake pipe and clear the blocked intake pipe, avoiding the complicated operation of manually switching and clearing the pipe when it is blocked. The structure is simple and does not require an additional drive source, thereby reducing production and maintenance costs while reducing the construction difficulty of the control system, making it more conducive to actual production use.

[0040] In addition, a first airbag 18 and a second airbag 19 are fixedly installed on opposite sides of the first baffle 14 and the second baffle 15, respectively. A fixed shell 20 is fixedly installed inside the first air intake pipe 3 and the second air intake pipe 4. A contraction airbag 21 is fixedly installed on each fixed shell 20, and the contraction airbag 21 is arranged in a fan shape.

[0041] The first airbag 18 is fixedly connected to the fixed shell 20 inside the first air intake pipe 3, and is also connected to the contractile airbag 21 inside the first air intake pipe 3 through the air hole 22; the second airbag 19 is fixedly connected to the fixed shell 20 inside the second air intake pipe 4, and is also connected to the contractile airbag 21 inside the second air intake pipe 4 through the air hole 22.

[0042] Furthermore, limit rods 23 are fixedly provided on the opposing sides of the two fixed shells 20, and second through holes 24 for the limit rods 23 to pass through are provided on the first baffle 14 and the second baffle 15.

[0043] Furthermore, an exhaust pipe 11 is fixedly installed at the top of the purification tower 1, and a drain pipe 12 is fixedly installed at the bottom of the purification tower 1.

[0044] Furthermore, two sets of spray pipes 7 are fixedly installed inside the purification tower 1, and an inlet pipe 6 is fixedly installed outside the purification tower 1. The output end of the inlet pipe 6 is connected to the two sets of spray pipes 7, and the input end of the inlet pipe 6 is connected to an external spray box (not shown in the figure).

[0045] Furthermore, two sets of support rings 9 are fixedly installed inside the purification tower 1. Each set of support rings 9 can be detachably equipped with a packing absorption layer 8, and a sealing door 10 can be detachably installed on the outer surface of the purification tower 1 at a position corresponding to the packing absorption layer 8.

[0046] It should be noted that the filler absorption layer 8 is used to increase the gas-liquid contact area and improve the gas flow and liquid distribution. This is in the prior art and will not be described in detail in this application.

[0047] Working principle: During use, exhaust gas is transported through the main intake pipe 51 to the diversion pipe 5, and then through the diversion pipe 5 to the first intake pipe 3 and the second intake pipe 4. The initial state is as follows. Figure 5 As shown, the first baffle 14 is located inside the first air inlet pipe 3 and is fitted onto the corresponding rubber cone 17. The second baffle 15 extends outside the second air inlet pipe 4. Therefore, the second air inlet pipe 4 is connected to the inside of the collecting pipe 2, so the gas will enter the purification tower 1 through the second air inlet pipe 4.

[0048] Subsequently, the pump inside the spray box is activated, injecting spray liquid into the two sets of spray pipes 7 through the inlet pipe 6. This allows the exhaust gas entering the collecting pipe 2 to pass upwards through the filtration of the two sets of packing absorption layers 8 and the spray purification of the two sets of spray pipes 7 before being discharged from the outlet pipe 11, ensuring that the exhaust gas is completely purified before being discharged. (It should be noted that during the above process, because the first through hole 16 on the first baffle 14 is fitted onto the outside of the corresponding rubber cone 17, the rubber cone 17 undergoes elastic deformation. Therefore, the rubber cone 17 provides sufficient friction to the first through hole 16, causing the exhaust gas to be obstructed when it reaches the first inlet pipe 3 through the diversion pipe 5 and unable to flow. Thus, the exhaust gas will enter the purification tower 1 through the second inlet pipe 4.)

[0049] As the purification process proceeds, dust and impurities will accumulate on the inner wall of the second air intake pipe 4, causing it to become blocked. When the second air intake pipe 4 becomes blocked, the exhaust gas input from the main air intake pipe 51 cannot be discharged through the second air intake pipe 4 in a timely manner, causing the air pressure in the diversion pipe 5 to gradually increase. The gradually increasing air pressure will act on the first baffle 14.

[0050] When the pressure inside the diversion pipe 5 is high enough, the exhaust gas will push the first baffle 14 to overcome the friction of the rubber cone 17, causing the first baffle 14 to move out of the first inlet pipe 3. The movement of the first baffle 14 will push the second baffle 15 into the second inlet pipe 4 through the connecting rod 25, so that the first inlet pipe 3 is connected to the collecting pipe 2, and the second inlet pipe 4 is disconnected from the collecting pipe 2, so that the exhaust gas enters the purification tower 1 for purification through the first inlet pipe 3.

[0051] At the same time, as the first baffle 14 moves, it stretches the first airbag 18, causing the first airbag 18 to extract the gas from the corresponding contraction airbag 21, causing the contraction airbag 21 to contract, so as to avoid the contraction airbag 21 from obstructing the flow of exhaust gas.

[0052] When the second baffle 15 enters the second intake pipe 4, as it moves, it scrapes away dust and impurities adhering to the inner wall of the second intake pipe 4, causing the dust and impurities to detach and loosen. Furthermore, the movement of the second baffle 15 compresses the second airbag 19, allowing gas from the second airbag 19 to enter the corresponding contraction airbag 21. This causes the contraction airbag 21 to inflate and block the lower part of the second intake pipe 4, preventing impurities pushed by the second baffle 15 from entering the diverter pipe 5.

[0053] When the first through hole 16 on the second baffle 15 is fitted onto the corresponding rubber cone 17, the rubber cone 17 will provide friction through deformation to limit and fix the second baffle 15.

[0054] As the first intake pipe 3 is used, blockage occurs within it. Because the impurities in the second intake pipe 4 become loose, the pressure in the diversion pipe 5 concentrates on the second baffle 15, causing it to overcome the friction of the rubber cone 17 and slide out of the second intake pipe 4. During this process, the exhaust gas blows away the detached impurities and dust, causing them to enter the purification tower 1. The impurities entering the purification tower 1 are then flushed out by the spray liquid flowing down the drain pipe 12.

[0055] Subsequently, the first baffle 14 is pushed back into the first air intake pipe 3 to scrape off the impurities and dust adhering to the inner wall of the first air intake pipe 3. In this way, the multi-stage spray VOCs treatment automatic system can automatically switch the air intake pipe and clear the blocked air intake pipe, avoiding the complicated operation of manually switching and clearing the pipe when it is blocked. The overall structure is simple and does not require the use of an additional drive source, thereby reducing production and maintenance costs while reducing the construction difficulty of the control system, making it more conducive to actual production use.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
