A purification processor for harmless emission of high-temperature exhaust gas

Abstract

This invention discloses a purification processor for the harmless emission of high-temperature exhaust gas, relating to the field of exhaust gas treatment technology. It includes a spray chamber, an exhaust port, an inlet pipe, a water film forming chamber, and a spray assembly. The spray assembly sprays liquid into the water film forming chamber to form a water film and a water network. The spray chamber also includes an airflow sensing and regulating mechanism connected to the spray assembly. When the pressure of the spiraling airflow in the water film forming chamber increases, the airflow sensing and regulating mechanism drives the spray assembly to move, causing the spray area to converge towards the inner center of the water film forming chamber. In this invention, by setting up a tangentially inlet "water film forming chamber," the exhaust gas forms a swirling flow upon entry, and dust particles are thrown to the inner wall under the action of centrifugal force and inertial force. Simultaneously, the large-area water network spray above the center provides secondary interception of the spiraling airflow, ensuring that the exhaust gas has full contact with water without any dead angles, avoiding the problem of dust being discharged directly without being washed.

Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a purification processor for the harmless emission of high-temperature waste gas. Background Technology

[0002] High-temperature waste gas treatment is an essential part of industrial production, especially in high-temperature processes such as steel smelting and thermal power generation. These waste gases contain a large number of harmful particulate matter such as sulfides and nitrogen oxides, which pose a threat to the environment and human health. Therefore, high-temperature waste gas treatment is of great significance for protecting the environment and human health.

[0003] A search revealed a Chinese patent with patent number CN222943183U, which discloses a high-temperature waste gas treatment device, including a treatment box. A drain pipe is installed at the bottom of the treatment box, an air inlet pipe is installed through the top of one side of the treatment box, an atomizing nozzle is installed on the water supply pipe, a dosing pipe is installed through the middle of the top of the treatment box, a servo motor is installed at the bottom of the other side of the treatment box, a horizontal shaft is installed at the output end of the servo motor, a stirring fan blade is fixedly installed on the horizontal shaft, and a transfer pipe is installed through the other end of the top of the treatment box.

[0004] The aforementioned existing technologies have the following drawbacks in practical applications: For high-temperature exhaust gases, when the inflow rate is large, the high-temperature airflow rapidly heats the sprayed water mist, causing the water mist to vaporize rapidly before completely capturing particulate matter. Simultaneously, the high airflow velocity shortens the residence time of the exhaust gas within the treatment chamber, leading to a severe imbalance in the gas-liquid ratio. At this point, the airflow is highly susceptible to penetrating the liquid phase region, causing airflow short-circuiting and droplet entrainment. This results in some dust particles being discharged with the airflow without sufficient washing, ultimately leading to a significant decrease in the treatment efficiency for high-temperature, high-flow-rate exhaust gases. Summary of the Invention

[0005] The purpose of this invention is to provide a purification processor for the harmless emission of high-temperature exhaust gas, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a purification processor for harmless emission of high-temperature waste gas, comprising a spray chamber, wherein the spray chamber is provided with an exhaust port and an air inlet pipe, the air inlet pipe extends into the interior of the spray chamber and is connected to a water film forming chamber, the water film forming chamber has a structure that is larger at the top and smaller at the bottom and is open at both the top and bottom, and the air inlet pipe is tangent to the periphery of the water film forming chamber; A spraying assembly is provided inside the spraying chamber and above the water film forming chamber. The spraying assembly is used to spray liquid into the water film forming chamber to form a water film and a water network. The spray chamber is also equipped with an airflow sensing and adjustment mechanism, which is connected to the spray assembly. When the pressure of the spiraling airflow in the water film forming chamber increases, the airflow sensing and adjustment mechanism can drive the spray assembly to move, causing the spray area to converge towards the inner center of the water film forming chamber.

[0007] Furthermore, the spray assembly includes a hollow frame, a winding plate, and multiple spray nozzles. The hollow frame is coaxially fixed to the inner wall of the spray chamber. The winding plate is in the shape of a spiral spring, with its outer end fixed and its inner end connected to a hollow sleeve. The multiple spray nozzles are distributed on the winding plate, and the spray nozzles are connected to the inner cavity of the hollow frame through pipelines.

[0008] Furthermore, the airflow sensing and adjustment mechanism includes a floating rod, a floating plate, a rotating sleeve, a rolling part, and an elastic element. A fixed sleeve is fixedly connected to the top of the spray chamber. The floating rod is circumferentially limited and vertically slidably inserted into the fixed sleeve. The floating plate is fixedly sleeved around the periphery of the floating rod and located on the flow path of the spiraling upward airflow. The rotating sleeve is coaxially rotatably sleeved outside the hollow sleeve and fixedly connected to the hollow sleeve. The floating rod passes through the central hole of the rotating sleeve. The rolling part is rotatably embedded in the wall of the central hole of the rotating sleeve. A spiral rolling groove is opened around the periphery of the floating rod, and the rolling part is engaged in the spiral rolling groove. The elastic element is disposed on the floating rod and is used to drive the floating plate to return to its original position downward when the airflow pressure decreases.

[0009] Furthermore, the hollow sleeve is rotatably connected to the mounting hole in the center of the hollow frame via a mounting bearing, and a coaxial annular connecting frame is fixed to the outer end of the winding sheet, the connecting frame being fixed to the inner wall of the spray chamber.

[0010] Furthermore, multiple pipe interfaces are fixedly connected to the wall surface of the hollow frame, and the multiple pipe interfaces are respectively connected to multiple spray nozzles through flexible hoses, and the pipe interfaces are in communication with the inner cavity of the hollow frame.

[0011] Furthermore, the periphery of the floating rod is connected to the central hole of the fixed sleeve by a key, so that the floating rod can slide freely along the axial direction and remain relatively stationary with respect to the fixed sleeve in the circumferential direction.

[0012] Furthermore, a stop ring is fixedly sleeved on the upper side of the floating rod, and the two ends of the elastic element in the elastic direction elastically abut against the lower end face of the stop ring and the upper surface of the floating plate, respectively.

[0013] Furthermore, there are two rolling parts, which are symmetrically arranged along the axial direction of the rotating sleeve, and there are two spiral rolling grooves, which respectively engage with the two rolling parts.

[0014] Furthermore, the outside of the spray chamber is equipped with a water tank and a water pump. The water inlet of the water pump is connected to the water tank, and the water outlet is connected to a spray pipe. The end of the spray pipe away from the water pump passes into the spray chamber and is connected to the spray assembly.

[0015] Furthermore, the air inlet pipe is horizontally inserted through the lower end of the spray chamber, the upper end of the water film forming chamber is coaxially fixed to the inner wall of the spray chamber, and one end of the air inlet pipe extending into the spray chamber is fixed to the lower outer wall of the water film forming chamber.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In the prior art, high-flow-rate, high-temperature airflow easily causes the sprayed water mist to rapidly vaporize and break through the liquid phase region, resulting in airflow short-circuiting. This invention addresses this by setting up a tangentially inlet "water film forming chamber," which creates a swirling flow after the exhaust gas enters. Dust particles are thrown to the inner wall under the action of centrifugal force and inertial force. Simultaneously, a large-area water spray above the center provides secondary interception of the spiraling airflow, ensuring that the exhaust gas fully contacts the water without any dead angles, thus avoiding the problem of dust being discharged directly without being washed. 2. In this invention, to address the problem of gas-liquid ratio imbalance caused by excessive initial velocity and unstable flow rate of exhaust gas, a purely mechanical airflow sensing and regulating mechanism is innovatively designed. When the pressure of the spirally rising airflow increases (high flow rate and high velocity), the airflow pushes the float plate upward. Through the cooperation of the spiral rolling groove on the floating rod and the rolling part, the linear motion is converted into rotational motion, causing the vortex spring-like winding plate to contract, making the spray nozzles automatically converge towards the center. This achieves dynamic adaptive regulation that "the greater the exhaust gas flow rate, the denser the spray in the central area and the greater the water volume," accurately compensating for the lack of liquid phase under high flow conditions. 3. In this invention, when the sprayed water impacts the inner wall of the water film forming chamber, it creates a splashing effect towards the center, forming a wide water network at the center of the chamber, significantly reducing the spray blind zone. Furthermore, the particles move upwards along the inner wall, while the water film flows downwards, creating a "counter-current convection washing" effect, which greatly prolongs the contact time between the particles and the water film, improving the water's encapsulation and capture rate of dust particles. 4. In this invention, the system can automatically adjust the spray density according to the airflow pressure to ensure that the exhaust gas is fully washed, cooled and washed with water during the rising process, avoiding the high-temperature and high-speed airflow from directly rushing out of the treatment area, thereby significantly reducing the water content and entrained droplets of the exhaust gas, and greatly reducing the treatment load of the subsequent demisting process. 5. In this invention, the detection of airflow and the adjustment of the spray range are entirely accomplished by a purely mechanical linkage structure such as the float, spiral groove, and winding blade, without relying on complex flow sensors, electric valves, or PLC control systems. In harsh industrial environments with high temperature, high humidity, and high dust, this purely mechanical adaptive structure has an extremely low failure rate, a long service life, and is easy to maintain.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7This invention provides a technical solution: a purification processor for harmless emission of high-temperature waste gas, including a spray chamber 6, an exhaust port 5 installed at the upper end of the spray chamber 6, an air inlet pipe 7 horizontally passing through the lower end of the spray chamber 6, a water film forming chamber 16 fixedly connected to one end of the air inlet pipe 7 that enters the inner cavity of the spray chamber 6, the upper end of the water film forming chamber 16 being coaxially fixed to the inner wall of the spray chamber 6, the outer diameter of the water film forming chamber 16 decreasing sequentially from top to bottom, and the upper and lower ends of the water film forming chamber 16 being open, a connecting cylinder being coaxially fixedly connected to the lower end of the water film forming chamber 16, one end of the air inlet pipe 7 extending into the spray chamber 6 being fixedly connected to the lower outer wall of the water film forming chamber 16, and the axial direction of the air inlet pipe 7 being tangent to the periphery of the water film forming chamber 16, a connecting frame 17 being coaxially fixedly connected to the inner wall of the spray chamber 6, the outer contour of the connecting frame 17 being annular, and the connecting frame 17 being installed above the water film forming chamber 16; Combination Figures 1 to 7 As shown, and please refer to the following: Figure 3 A water tank 1 is welded to the outer wall of the spray chamber 6. A water pump 2 is installed on the top of the water tank 1. The inlet of the water pump 2 is connected to the inner cavity of the water tank 1 through a pipe. A spray pipe 3 is installed at the outlet of the water pump 2. The end of the spray pipe 3 away from the water pump 2 passes through the spray chamber 6. A hollow frame 12 is coaxially fixed to the inner wall of the spray chamber 6. The hollow frame 12 is hollow inside. The end of the spray pipe 3 that passes through the spray chamber 6 is in a through-connection state with the inner cavity of the hollow frame 12, so that when the water pump 2 starts, it can transport water from the water tank 1 to the spray pipe 3. Then, it is transported by the spray pipe 3 to the inner cavity of the hollow frame 12. The annular hole wall of the connecting frame 17 is fixed with a winding plate 15. The outer contour of the winding plate 15 is in the shape of a spiral spring, and the outer end of the winding plate 15 is fixed to the annular hole wall of the connecting frame 17. The inner end of the winding plate 15 is fixed with a hollow sleeve 18. The hollow sleeve 18 is coaxial with the spray chamber 6. When the hollow sleeve 18 rotates around its own circumference, it can generate a contraction force on the winding plate 15, thereby making the winding plate 15 in an elastic contraction state and accumulating elastic potential energy. Combination Figures 1 to 7 As shown, and please refer to the following: Figure 6Multiple spray nozzles 14 are welded onto the winding sheet 15, and the spray nozzles 14 are evenly distributed on the winding sheet 15 and located above the water film forming chamber 16. Multiple pipe interfaces 13 are fixed to the wall of the perforated frame 12, and the multiple pipe interfaces 13 are connected to the multiple spray nozzles 14 respectively through flexible hoses. The pipe interfaces 13 are in communication with the inner cavity of the perforated frame 12. When the water pump 2 delivers water to the inner cavity of the perforated frame 12, the water in the inner cavity of the perforated frame 12 will be delivered to the spray nozzles 14 through the pipe interfaces 13, and then sprayed by the spray nozzles 14 towards the water film forming chamber 16 below. Inside the water film forming chamber 16, water sprayed from the spray nozzles 14 near the outer side of the spray chamber 6 flows into the upper inner wall of the water film forming chamber 16. On the one hand, since the sprayed water has a certain flow velocity, it will produce a splashing effect on the upper inner wall of the water film forming chamber 16. That is, the water falling on the upper inner wall of the water film forming chamber 16 forms a water film towards the center of the water film forming chamber 16 under the impact force of the inner wall of the water film forming chamber 16. This makes a large water network formed at the center of the water film forming chamber 16, expanding the spray range and reducing the spray blind zone. On the other hand, some of the water flowing into the inner wall of the water film forming chamber 16 will flow along the inner wall of the water film forming chamber 16. In this way, the exhaust gas entering the water film forming chamber 16 tangentially has a certain initial velocity, so it can generate a swirling flow in the water film forming chamber 16. Under the action of centrifugal force or inertial force, the particulate matter in the exhaust gas can flow along the inner wall of the water film forming chamber 16 for a certain distance, and the direction of the flow is opposite to the direction of the water flow on the inner wall of the water film forming chamber 16. That is, the particulate matter flows from bottom to top, and the water flows from top to bottom. This allows the particulate matter and the water flow to come into full contact, so that the particulate matter can be fully wrapped by the water. Since the exhaust gas is relatively light after entering the water film forming chamber 16, the airflow formed by the exhaust gas will flow along the path with less resistance. At this time, the exhaust gas will spiral up in the water film forming chamber 16. Since the spray nozzle 14 in the middle of the connecting frame 17 can spray the exhaust gas, and due to the splashing, the water network formed in the center of the water film forming chamber 16 has a large range, so the spraying range of the exhaust gas is large. Combination Figures 1 to 7 As shown, and please refer to the following: Figure 6If the initial velocity of the exhaust gas is too high, it may cause the exhaust gas to spiral upwards at a high velocity within the water film forming chamber 16, resulting in insufficient spraying of the exhaust gas and consequently a high water content in the exhaust gas, which puts greater pressure on subsequent demisting. Therefore, in this embodiment, an installation hole is opened in the middle of the hollow frame 12, and the upper end of the hollow sleeve 18 passes through the installation hole. The hollow sleeve 18 is rotatably connected to the installation hole through an installation bearing, thereby allowing the hollow sleeve 18 to be rotatably connected to the hollow frame 12. The hollow sleeve 18 is coaxial inside. A rotating sleeve 19 is provided and fixed to a hollow sleeve 18. When the rotating sleeve 19 rotates, it will synchronously drive the hollow sleeve 18 to rotate. A fixed sleeve 4 is fixedly installed on the top of the spray chamber 6. A floating rod 8 is coaxially provided on the fixed sleeve 4. The floating rod 8 can slide freely vertically on the fixed sleeve 4, and the periphery of the floating rod 8 and the central hole of the fixed sleeve 4 are keyed together. This allows the floating rod 8 to slide freely on the fixed sleeve 4, and the floating rod 8 and the fixed sleeve 4 remain relatively stationary in the circumferential direction. Combination Figures 1 to 7 As shown, and please refer to the following: Figure 6 A float plate 11 is fixedly sleeved on the periphery of the floating rod 8. When the float plate 11 is subjected to the force of the spiraling upward airflow, it can move upward with the airflow, thereby driving the floating rod 8 to move upward. The floating rod 8 passes through the central hole of the rotating sleeve 19. Two rolling parts 20 are rotatably embedded in the wall of the central hole of the rotating sleeve 19. The two rolling parts 20 are symmetrically arranged along the axial direction of the rotating sleeve 19. In addition, two spiral rolling grooves 21 are opened on the periphery of the floating rod 8. The two rolling parts 20 are respectively engaged in the two spiral rolling grooves 21 and can roll freely in the spiral rolling grooves 21. When the floating rod 8 moves up and down, the two rolling parts 20 will... The 0 rolls in the two spiral rolling grooves 21 respectively. Since the floating rod 8 is keyed to the fixed sleeve 4, the rotating sleeve 19 can rotate. When the rotating sleeve 19 rotates, it will drive the hollow sleeve 18 to rotate. When the hollow sleeve 18 rotates, it will cause the winding plate 15 to undergo elastic contraction deformation, so that the spray nozzles 14 on the winding plate 15 can converge towards the inner side of the center of the water film forming chamber 16, thereby making the spray in the middle area of ​​the water film forming chamber 16 more concentrated, or in other words, the water flow rate sprayed in the middle area of ​​the water film forming chamber 16 is greater. This makes the spraying effect of the spray water on the exhaust gas better when the exhaust gas spirals upward. In addition, a stop ring 9 is fixedly sleeved on the upper side of the floating rod 8, and an elastic element 10 is provided between the float plate 11 and the stop ring 9. The two ends of the elastic element 10 elastically abut against the lower end face of the stop ring 9 and the upper surface of the float plate 11, respectively. When the float plate 11 moves upward, it generates elastic compression on the elastic element 10, thereby enabling the elastic element 10 to accumulate elastic potential energy. When the pressure of the spiraling upward airflow decreases, the elastic potential energy accumulated by the elastic element 10 will exert a downward force on the float plate 11, thereby enabling the float plate 11 to move downward and reset.

[0021] Working principle of the invention: After being pretreated and cooled, the high-temperature exhaust gas is introduced into the inlet pipe 7 and then enters the water film forming chamber 16 through the inlet pipe 7. The exhaust gas has a certain initial velocity, which allows it to flow along the inner wall of the water film forming chamber 16, thus creating a swirling flow within the chamber. This causes the particulate matter in the exhaust gas to be thrown into the inner wall of the chamber. The water sprayed from the spray nozzle 14 forms a water film on the inner wall of the chamber. This water film flows from top to bottom, preventing the particles from contacting the water in the water film and being encapsulated by it. The exhaust gas spirals upward in the central area of ​​the water film forming chamber 16, and the spray nozzle 14 above the center of the chamber sprays the exhaust gas. When the pressure of the spiraling exhaust gas is high, the thrust generated by the exhaust gas on the float plate 11 increases, which in turn causes the float plate 11 to overcome the elastic resisting force of the elastic element 10 on the float plate 11 and move upward. When the float plate 11 moves upward, the floating rod 8 will move upward synchronously. Since the floating rod 8 is keyed to the fixed sleeve 4, when the floating rod 8 moves upward, the rolling part 20 will roll in the spiral rolling groove 21, and the rotating sleeve 19 will rotate. When the rotating sleeve 19 rotates, it will drive the hollow sleeve 18 to rotate. When the hollow sleeve 18 rotates, the winding plate 15 will be in an elastic contraction state, which will cause the spray nozzles 14 on the periphery of the winding plate 15 to move towards the inner side of its center, thereby increasing the spray volume in the central area of ​​the water film forming chamber 16, so that the exhaust gas can be fully sprayed.
