Description

Technical Field

[0001] This utility model relates to the field of industrial production, and in particular to the inlet flue of a quench deacidification tower. Background Technology

[0002] The inlet flue of the quench desulfurization tower is a key conveying component in the industrial flue gas purification system that connects the upstream flue gas generating equipment with the quench desulfurization tower. Its core function is to stably transport the high-temperature acidic flue gas generated by processes such as waste incineration and hazardous waste treatment to the quench desulfurization tower, providing a pre-conditioning for subsequent processes such as rapid cooling of flue gas and neutralization of acidic gases. It is an important hub to ensure the continuous operation of the entire purification system.

[0003] The inlet flue of the quench deacidification tower mostly adopts a combination structure of straight and bent pipes made of carbon steel or stainless steel. Some flues have metal filters that can be detachably installed near the inlet of the deacidification tower to achieve initial interception of large particulate impurities.

[0004] The existing technology has the following drawbacks: Existing methods use metal mesh to filter particulate impurities, but after long-term use, dust accumulation will clog the pores of the mesh, resulting in restricted flue gas intake. This requires cleaning the mesh by disassembling and reassembling it, and frequent maintenance will consume a lot of manpower and time, reducing the efficiency of the process to a certain extent. Therefore, a quenching deacidification tower inlet flue is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an inlet flue of a rapid cooling deacidification tower, which aims to improve the problem of filter screen clogging and difficulty in unclogging in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inlet flue of a quenching deacidification tower, comprising a conveying pipe, a connecting frame fixedly connected to the left end of the conveying pipe, a connecting pipe fixedly connected to the left end of the connecting frame, a filter frame detachably installed on the inner wall of the connecting frame, a movable frame slidably connected to the inner wall of the connecting frame, a hammer fixedly connected to the left side wall of the movable frame, an elastic connection between the right side wall of the movable frame and the connecting frame via a return spring, a pressing mechanism provided on the right side wall of the movable frame, a flange fixedly connected to the outer wall of the connecting pipe, a collection frame detachably installed at the bottom end of the connecting frame, and a sealing mechanism provided on the left side wall of the connecting pipe;

[0007] The extrusion mechanism includes an extrusion plate, which is fixedly connected to the right side wall of the movable frame. The inner side wall of the extrusion plate contacts an extrusion disc, and the outer wall of the extrusion disc is fixedly connected to a motor.

[0008] As a further description of the above technical solution:

[0009] The sealing mechanism includes a rubber ring, which is fixedly connected to the left side wall of the connecting pipe. A fixing pipe is provided at the left end of the connecting pipe, and an annular groove is provided on the right side wall of the fixing pipe. An air bladder is fixedly connected to the inner wall of the annular groove, and a sealing gasket is fitted between the connecting pipe and the fixing pipe.

[0010] As a further description of the above technical solution:

[0011] The sidewall of the rubber ring is in contact with the sidewall of the airbag.

[0012] As a further description of the above technical solution:

[0013] The rubber ring is inserted into the inner wall of the ring groove.

[0014] As a further description of the above technical solution:

[0015] The flange is fixedly connected to the outer wall of the fixed pipe.

[0016] As a further description of the above technical solution:

[0017] The right sidewall of the movable frame is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the right inner wall of the connecting frame.

[0018] As a further description of the above technical solution:

[0019] The extrusion plate is slidably connected to the inner wall of the connecting frame.

[0020] As a further description of the above technical solution:

[0021] The motor is fixedly connected to the outer wall of the conveying pipe, and the left end of the hammer is in contact with the right end of the filter frame.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the filter screen can accurately intercept large particulate impurities in high-temperature acidic flue gas, preventing impurities from clogging the quench spray gun nozzle and wearing down the core components inside the tower, thus significantly reducing the probability of the deacidification tower failure and downtime. At the same time, relying on the motor-driven extrusion and hammer reset, the filter frame can be periodically struck to shake the dust attached to the filter screen surface into the collection frame. Dust removal can be completed without frequent disassembly, which not only maintains long-term filtration efficiency but also extends the service life of the filter screen, reducing operation and maintenance costs and workload.

[0024] 2. In this utility model, the triple cooperation of the hard rubber ring, airbag, and sealing gasket forms a double seal. The rubber ring is inserted into the ring groove and squeezes the airbag to create a tight fit. The sealing gasket further fills the gap, which can effectively block the leakage of high-temperature acidic flue gas from the connection gap. This design not only avoids the environmental risks and personnel safety hazards caused by flue gas leakage, but also avoids the loss of flue gas volume due to leakage, ensuring the stability and efficiency of the subsequent deacidification process and improving the overall purification effect.

[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 Figures 1-3This utility model provides an embodiment of a quenching deacidification tower inlet flue, including a conveying pipe 1, a connecting frame 2 fixedly connected to the left end of the conveying pipe 1, and a connecting pipe 3 fixedly connected to the left end of the connecting frame 2. The conveying pipe 1, the connecting frame 2, and the connecting pipe 3 constitute the entire quenching deacidification tower inlet flue, allowing high-temperature acidic flue gas to be conveyed into the quenching deacidification tower. A filter frame 4 is detachably installed on the inner wall of the connecting frame 2, and a filter screen is provided on the filter frame 4. The filter screen is made of ultra-low carbon austenitic stainless steel, which can withstand long-term dust erosion and is not easily deformed. It can block impurities and dust from entering the quenching deacidification tower, avoiding physical damage to the core components inside the tower. A movable frame 5 is slidably connected to the inner wall of the connecting frame 2, and a striking hammer 6 is fixedly connected to the left side wall of the movable frame 5. The contact point 6 is located at the perimeter of the filter frame 4 and will not directly contact the filter screen. The right side wall of the moving frame 5 is elastically connected to the connecting frame 2 via a return spring 7. The return spring 7 is made of nickel-based high-temperature alloy material, which is resistant to high temperature and corrosion. The right side wall of the moving frame 5 is provided with a pressing mechanism. The outer wall of the connecting pipe 3 is fixedly connected with a flange 12. The flange 12 can be bolted to connect the fixed pipe 14 and the connecting pipe 3 to ensure the stability of the connection. The bottom of the connecting frame 2 is detachably equipped with a collection frame 11, which can collect dust and impurities after the filter screen is knocked. The top of the collection frame 11 is made of sealing rubber material. After the top of the collection frame 11 is installed in contact with the surface of the connecting frame 2, it can ensure a seal. The left side wall of the connecting pipe 3 is provided with a sealing mechanism.

[0034] The extrusion mechanism includes an extrusion plate 8, which is fixedly connected to the right side wall of the moving frame 5. When the extrusion plate 8 is L-shaped and is extruded, it will cause the extrusion plate 8 to move laterally with the moving frame 5. The inner side wall of the extrusion plate 8 contacts an extrusion disc 10. The protrusion on the extrusion disc 10 is inclined, which can be used to extrude the extrusion plate 8 to generate movement. The outer wall of the extrusion disc 10 is fixedly connected to a motor 9. The output shaft of the motor 9 is connected to the extrusion disc 10, which can cause the extrusion disc 10 to rotate.

[0035] Reference Figures 4-5 The sealing mechanism includes a rubber ring 13, which is fixedly connected to the left side wall of the connecting pipe 3. The rubber ring 13 is made of hard rubber material, which can fully compress the airbag 16 to deform it. A fixing pipe 14 is provided at the left end of the connecting pipe 3. The fixing pipe 14 is the existing connection end fixed to the quench deacidification tower, which facilitates subsequent connection and installation with the connecting pipe 3. An annular groove 15 is opened on the right side wall of the fixing pipe 14. The airbag 16 is fixedly connected to the inner wall of the annular groove 15. A sealing gasket 17 is attached between the connecting pipe 3 and the fixing pipe 14. The sealing gasket 17 can play the role of the first layer of sealing. The side wall of the rubber ring 13 is in contact with the side wall of the airbag 16. The rubber ring 13 is inserted into the inner wall of the annular groove 15. The annular groove 15 is the same size as the rubber ring 13.

[0036] Reference Figures 1-3 Flange 12 is fixedly connected to the outer wall of fixed pipe 14. The right side wall of moving frame 5 is fixedly connected to one end of return spring 7. When moving frame 5 moves to the right, it will compress return spring 7. When resetting, the elastic force of return spring 7 is used to move moving frame 5 to reset. The other end of return spring 7 is fixedly connected to the inner wall of right end of connecting frame 2. Extrusion plate 8 is slidably connected to the inner wall of connecting frame 2. Motor 9 is fixedly connected to the outer wall of conveying pipe 1. The left end of hammer 6 is in contact with the right end of filter frame 4.

[0037] Working Principle: When the entire device is in use, high-temperature acidic flue gas enters through the conveying pipe 1, flows sequentially through the connecting frame 2, connecting pipe 3, and finally to the fixed pipe 14, and is ultimately delivered to the quench deacidification tower. During this process, the flue gas first passes through the filter frame 4 inside the connecting frame 2. The filter screen, thanks to the erosion-resistant properties of ultra-low carbon austenitic stainless steel, intercepts large particles of impurities in the flue gas, preventing these impurities from entering the deacidification tower with the flue gas and clogging the quench spray nozzles or wearing down the core components inside the tower. As operating time increases, dust and impurities easily adhere to the surface of the filter screen, requiring regular cleaning. The motor 9, fixed to the outer wall of the conveying pipe 1, is started. The output shaft of motor 9 drives the extrusion disc 10 to rotate. The inclined protrusion on the 0 contacts the inner side wall of the extrusion plate 8. The inclined extrusion pushes the extrusion plate 8 to slide along the inner wall of the connecting frame 2, thereby driving the moving frame 5 to move laterally. When the moving frame 5 moves, it will compress the reset spring 7 connected to its right side wall. At the same time, the hammer 6 fixed to its left side wall will move away from the filter frame 4. When the protrusion of the extrusion plate 10 is no longer in contact with the extrusion plate 8, the reverse elastic force of the reset spring 7 will move the extrusion plate 8 to the left to reset. The extrusion plate 8 resets the moving frame 5 and the hammer 6, allowing the hammer 6 to strike the filter frame 4, causing the dust and impurities attached to the filter screen surface to fall off. The fallen dust and impurities fall into the collection frame 11 at the bottom of the connecting frame 2 under the action of gravity.

[0038] Throughout the flue gas transport process, the rubber ring 13 at the left end of the connecting pipe 3 is inserted into the annular groove 15 of the fixed pipe 14. The hard rubber ring 13 squeezes the air bladder 16 on the inner wall of the annular groove 15, causing it to deform and fit tightly against the rubber ring 13. Together with the sealing gasket 17 between the connecting pipe 3 and the fixed pipe 14, a double seal is formed, effectively preventing high-temperature acidic flue gas from leaking from the connection.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
