Description

Technical Field

[0001] This utility model relates to the field of exhaust gas purification technology, specifically to an exhaust gas purification device for high-tower compound fertilizer granulation. Background Technology

[0002] Compound fertilizers are chemical fertilizers containing two or more nutrients. They have advantages such as high nutrient content, fewer byproducts, and good physical properties, playing a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. During the processing of compound fertilizers, the exhaust gas contains dust and particulate matter, requiring filtration of these particles during emission.

[0003] Existing technologies, such as the utility model with authorization publication number CN213313979U, have the advantages of simple operation, increased filter plate lifespan, and improved exhaust gas treatment safety.

[0004] Currently, there is a lack of exhaust gas purification equipment for high-tower compound fertilizer granulation that can achieve multiple filtrations, including dust and particle filtration, and utilize solutions to neutralize acidic gases to treat the exhaust gas. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tail gas purification device for high-tower compound fertilizer granulation, which realizes multiple filtration, dust and particle filtration, and utilizes solution to neutralize acidic gas to treat the tail gas.

[0006] This utility model achieves its invention objective using the following technical solution:

[0007] A tail gas purification device for high-tower compound fertilizer granulation is characterized by comprising: a water tank assembly, serving as a terminal absorption device, which dissolves soluble gases and settles particulate matter through water; a first filter box assembly, installed on the upper side wall of the water tank assembly; a second filter box assembly, installed on the upper side wall of the water tank assembly, with the first filter box assembly fixedly connected to the second filter box assembly; forming a two-stage pretreatment system for dry filtration (dust removal); and a spray assembly, disposed inside the water tank assembly, to enhance gas-liquid contact efficiency and neutralize acidic gases through an atomized water curtain. This constructs a multi-stage purification system, realizing a complete treatment chain for tail gas from gaseous pollutants to liquid absorption.

[0008] As a further limitation of this technical solution, the water tank assembly includes a water tank, which is fixedly connected to an exhaust pipe to discharge purified gas; the first filter box assembly includes a first filter box, which is fixedly connected to a first air inlet pipe and a first air outlet pipe. The first air inlet pipe introduces exhaust gas, and coarse particles initially settle due to gravity; the first air outlet pipe guides the pretreated gas to the second stage; the second filter box assembly includes a circular box, which is fixedly connected to the first air outlet pipe, and the circular box is fixedly connected to a second air outlet pipe. The second air outlet pipe passes through the water tank in a sealed manner and is provided with two sets of exhaust holes to disperse the gas after secondary filtration into the water tank, increasing the contact area with water; the circular box is bearing-connected to the central shaft of the rotating roller, and the rotating roller is fixedly connected to a set of mounting frames. Each mounting frame is fixedly connected to a second filter plate, and the mounting frame matches the circular box. The rotational design allows the filter plates to periodically contact the airflow, avoiding local blockage. The first filter box and the circular box are respectively fixedly connected to the water tank.

[0009] As a further limitation of this technical solution, the exhaust holes are distributed at an angle.

[0010] As a further limitation of this technical solution, a booster pump is installed on the first exhaust pipe. This compensates for the pressure drop between the first filter box and the circular box, making it particularly suitable for scenarios with high-viscosity dust or high-humidity exhaust gas, and preventing airflow stagnation from causing a decrease in purification efficiency.

[0011] As a further limitation of this technical solution, a set of mounting plates is provided inside the first filter box. One of the adjacent mounting plates is fixedly connected to the top plate of the first filter box, and the other of the adjacent mounting plates is fixedly connected to the bottom plate of the first filter box. The adjacent mounting plates are fixedly connected to the first filter plate. This forms an "S-shaped" airflow channel. Particles settle due to inertial impact on the mounting plates, and the first filter plate intercepts fine particles.

[0012] As a further limitation of this technical solution, the spray assembly includes a set of water pipes, each of which is connected to the water tank by a bearing, and each of which is fixedly connected to a set of nozzles. This allows the water pipes to swing, enabling the nozzles to spray at multiple angles and avoiding dead zones in the water mist.

[0013] As a further limitation of this technical solution, each water pipe is fixedly connected to a rocker arm, and each rocker arm rotates to connect to a parallel rod, which is fixedly connected to a vertical groove. By driving the vertical groove to move, the parallel rod drives a set of rocker arms to move, thereby realizing the oscillation of a set of water pipes.

[0014] As a further limitation of this technical solution, a transmission assembly is also included. The transmission assembly includes a large gear, which is fixedly connected to the central shaft of the rotating roller. A small gear is connected to the circular bearing, and the large gear meshes with the small gear. The water tank bearing is connected to the central shaft of the rotating wheel. Synchronous pulleys are fixedly connected to the small gear and the central shaft of the rotating wheel, respectively. The two ends of the synchronous belt are respectively wrapped around the corresponding synchronous pulleys. A circular block is fixedly connected to the eccentric part of the rotating wheel, and the circular block is disposed within the vertical groove. The exhaust gas flow drives the rotating roller to rotate, and mechanical energy is transmitted to the spraying system, reducing the need for external power.

[0015] Compared with related technologies, the exhaust gas purification equipment for high-tower compound fertilizer granulation provided by this utility model has the following beneficial effects:

[0016] (1) The first filter box assembly and the second filter box assembly are connected in series to form a two-stage pretreatment for dry filtration (dust removal).

[0017] (2) The mounting plate and the first filter box form an “S-shaped” airflow channel. Particles settle due to inertial impact on the mounting plate, and the first filter plate intercepts fine particles. The pressurization pump compensates for the pressure drop of the first filter box to ensure smooth gas flow, especially in high-viscosity dust or high-humidity exhaust gas scenarios, to prevent airflow stagnation from causing a decrease in purification efficiency. The second filter plate periodically contacts the airflow to avoid local blockage and extend its service life.

[0018] (3) The nozzle sprays water mist at multiple angles to enhance the gas-liquid contact efficiency. By neutralizing acidic gas through atomized water curtain, the exhaust gas is further purified. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example 1: A tail gas purification device for high-tower compound fertilizer granulation includes: a water tank assembly 4, serving as a terminal absorption device, which dissolves soluble gases and settles particulate matter through water; a first filter box assembly 1, installed on the upper side wall of the water tank assembly 4; a second filter box assembly 2, installed on the upper side wall of the water tank assembly 4, with the first filter box assembly 1 fixedly connected to the second filter box assembly 2; forming a two-stage pretreatment for dry filtration (dust removal); and a spray assembly 5, disposed inside the water tank assembly 4, enhancing gas-liquid contact efficiency and neutralizing acidic gases through an atomized water curtain. This constructs a multi-stage purification system, realizing a complete treatment chain for tail gas from gaseous pollutants to liquid absorption.

[0031] The water tank assembly 4 includes a water tank 41, which is fixedly connected to an exhaust pipe 42 to discharge purified gas; the first filter box assembly 1 includes a first filter box 11, which is fixedly connected to a first air inlet pipe 12 and a first air outlet pipe 15. The first air inlet pipe 12 introduces exhaust gas, and coarse particles initially settle due to gravity; the first air outlet pipe 15 guides the pretreated gas to the second stage; the second filter box assembly 2 includes a circular box 21, which is fixedly connected to the first air outlet pipe 15. A second vent pipe 22, which seals and passes through the water tank 41, is provided with two sets of vent holes 23 to disperse the gas after secondary filtration into the water tank 41, increasing the contact area with water. The circular box 21 is bearing-connected to the central shaft of the rotating roller 24, which is fixedly connected to a set of mounting frames 26. Each mounting frame 26 is fixedly connected to a second filter plate 25, and the mounting frame 26 matches the circular box 21. The rotational design allows the filter plate 25 to periodically contact the airflow, avoiding local blockage. The first filter box 11 and the circular box 21 are respectively fixedly connected to the water tank 41.

[0032] The exhaust ports 23 are distributed at an angle.

[0033] A booster pump 16 is installed on the first exhaust pipe 15. It compensates for the pressure drop between the first filter box 11 and the circular box 21, and is especially suitable for high-viscosity dust or high-humidity exhaust gas scenarios, preventing airflow stagnation from causing a decrease in purification efficiency.

[0034] The spray assembly 5 includes a set of water pipes 51, each of which is connected to the water tank 41 by a bearing, and each of which is fixedly connected to a set of nozzles 52. The water pipes 51 are allowed to swing, and the nozzles 52 spray at multiple angles to avoid dead zones in the water mist.

[0035] Each water pipe 51 is fixedly connected to a rocker arm 53, and each rocker arm 53 rotates to connect to a parallel rod 55, which is fixedly connected to a vertical groove 54. By driving the vertical groove 54 to move, the parallel rod 55 drives a set of rocker arms 53 to move, thereby realizing the swinging of a set of water pipes 51.

[0036] The working principle of the exhaust gas purification equipment for high-tower compound fertilizer granulation provided by this utility model is as follows:

[0037] Connect one end of a hose to water pipe 51 and the other end to the neutralizing liquid source. Connect one end of a hose to vent pipe 42 and the other end to the gas collection system.

[0038] The exhaust gas is introduced into the first intake pipe 12, where it undergoes preliminary filtration in the first filter box 11. The pre-filtered gas then enters the second filter box assembly 2 through the first outlet pipe 15. The pressurization pump 16 starts working to compensate for the pressure drop in the first filter box 11, ensuring smooth gas flow, especially in scenarios with high-viscosity dust or high-humidity exhaust gas, preventing airflow stagnation that could reduce purification efficiency. In the second filter box assembly 2, the gas blows and moves the second filter plates 25 in contact with it, causing the rotating roller 24 to rotate, thus moving a set of second filter plates 25. This ensures that the second filter plates 25 periodically contact the airflow, preventing localized blockages and extending their service life. The gas is further filtered by the second filter plates 25, intercepting fine particulate matter.

[0039] At this point, the spray assembly 5 begins to operate. The water pipe 51 swings under the influence of the rocker arm 53, the parallel rod 55, and the vertical groove 54. The nozzle 52 sprays water mist at multiple angles, enhancing gas-liquid contact efficiency. By neutralizing the acidic gas through the atomized water curtain, further purification of the exhaust gas is achieved. Finally, the purified gas is discharged through the exhaust pipe 42 of the water tank 41, completing the entire purification process.

[0040] In this embodiment, additional power is required to move the vertical channel 54, thereby enabling the water pipe 51 to swing.

[0041] Example 2: This example further elaborates on Example 1. A set of mounting plates 13 is provided inside the first filter box 11. One of adjacent mounting plates 13 is fixedly connected to the top plate of the first filter box 11, and the other of adjacent mounting plates 13 is fixedly connected to the bottom plate of the first filter box 11. Adjacent mounting plates 13 are fixedly connected to first filter plates 14. This forms an "S-shaped" airflow channel. Particles settle due to inertia impacting the mounting plates 13, while the first filter plates 14 intercept fine particles.

[0042] The working principle of the exhaust gas purification equipment for high-tower compound fertilizer granulation provided by this utility model is as follows:

[0043] The exhaust gas is introduced into the first intake pipe 12. The exhaust gas undergoes preliminary filtration in the first filter box 11. Coarse particles settle initially on the first filter plate 14 due to gravity. The gas that has undergone preliminary filtration enters the second filter box assembly 2 through the first exhaust pipe 15.

[0044] Example 3: This example further elaborates on Example 1 or 2, and also includes a transmission assembly 3. The transmission assembly 3 includes a large gear 36, which is fixedly connected to the central shaft of the rotating roller 24. A small gear 31 is connected to the bearing of the circular box 21, and the large gear 36 meshes with the small gear 31. The central shaft of the rotating wheel 35 is connected to the bearing of the water tank 41. The central shafts of the small gear 31 and the rotating wheel 35 are respectively fixedly connected to synchronous pulleys 32. The two ends of the synchronous belt 33 are respectively wrapped around the corresponding synchronous pulleys 32. A circular block 34 is fixedly connected to the eccentric part of the rotating wheel 35, and the circular block 34 is disposed in the vertical groove 54. The exhaust gas flow drives the rotating roller 24 to rotate, and the mechanical energy is transmitted to the spraying system, reducing the external power requirement.

[0045] The transmission component 3 can be protected by installing a protective cover, which can be placed within the area formed by the protective cover and the water tank 41.

[0046] The working principle of the exhaust gas purification equipment for high-tower compound fertilizer granulation provided by this utility model is as follows:

[0047] When the rotating roller 24 rotates, it drives the large gear 36 to rotate, the large gear 36 drives the small gear 31 to rotate, the small gear 31 drives the lower synchronous wheel 32 to rotate, the lower synchronous wheel 32 drives the synchronous belt 33 to move, the synchronous belt 33 drives the rotating wheel 35 to rotate, the rotating wheel 35 drives the round block 34 to swing in the vertical groove 54, the round block 34 drives the vertical groove 54 to swing, the vertical groove 54 drives the parallel rod 55 to swing, the parallel rod 55 drives the rocker arm 53 to swing, the rocker arm 53 drives the water pipe 51 to swing, and the water pipe 51 drives the nozzle 52 to swing.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
