Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas treatment equipment, and particularly relates to a kiln tail gas treatment equipment for ceramic pigment processing. Background Art

[0002] Kiln tail gas treatment is an important environmental protection link, aiming to reduce the environmental pollution caused by harmful gases and particulate matters generated during the combustion process of the kiln. When treating the kiln tail gas, in order to remove sulfides, nitrides and nitrates in the kiln tail gas, generally, the dust-removed kiln tail gas is introduced into a spray tower for spraying operation, so as to neutralize sulfides, nitrides and nitrates in the kiln tail gas by using the alkaline solution sprayed by the spray pipe, and then enable the kiln tail gas to meet the discharge standards.

[0003] However, when introducing the kiln tail gas into the spray tower, since the flow rate of the kiln tail gas is unstable and uneven during introduction, and the flow rate during spraying of the spray pipe is fixed, when the amount of tail gas introduced is small, the sprayed alkaline solution will be relatively excessive, resulting in waste of the alkaline solution.

[0004] Therefore, it is necessary to invent a kiln tail gas treatment equipment for ceramic pigment processing to solve the above problems. Summary of the Invention

The two ends of the reset spring on the push rod at the bottom are respectively fixedly connected to the baffle plate and the adjacent fixing ring.

[0012] Further, the connecting assembly includes an L-shaped connecting rod, two movable rings, two blocking strips and two connecting columns.

[0017] Technical effects and advantages of the present invention:

[0018] 1. In the present invention, by providing an adjustment assembly, during the process of spraying the tail gas with the alkaline solution, as the amount of the tail gas introduced changes, the adjustment assembly opposite to the intake pipe can drive the adjustment assembly opposite to the liquid inlet pipe and make adjustments through the connection assembly, thereby controlling the spraying amount of the alkaline solution, so that the alkaline solution can change synchronously according to the change of the amount of the tail gas introduced, avoiding waste of excessive alkaline solution;

[0019] 2. In the present invention, by providing a movable ball, when the tail gas in the exhaust plate is ejected through the movable ball, the gas can be ejected upward under the guiding action of the movable ball, thereby avoiding the tail gas being sprayed obliquely on the inner wall of the spray pipe, resulting in the alkaline solution being unable to contact the tail gas. When the tail gas contacts the protective cover, the tail gas can be ejected evenly along the bottom edge of the protective cover under the blocking of the protective cover, thereby increasing the ejection area of the tail gas, enabling the nitrogen, sulfur, and nitrogen oxides in the tail gas to contact the alkaline solution more evenly, and improving the treatment effect of the alkaline solution on the tail gas;

[0020] 3. In the present invention, by providing a top rod, when the baffle drives the movable ring to move together through the connecting column under the push of the air flow, the L-shaped rod can drive the top rod to jack up the top plate upward, so that the exhaust plate can swing up and down, and further change the jet area of the exhaust holes at the top of the exhaust plate, enabling the exhaust plate to better meet the spraying requirements of the alkaline solution when the intake amount of the kiln tail gas is different.

Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] The present invention provides a Figures 1 to 10 shown kiln tail gas treatment device for ceramic pigment processing, including a spray tower 1, a spray pipe 2 is arranged in the spray tower, a gas guiding assembly is arranged at the bottom of the spray pipe 2, and the gas guiding assembly includes a gas duct 3, two exhaust plates 4, two arc plates 5, and a leak-proof sleeve 6;

[0034] The two exhaust plates 4 are symmetrically distributed on the front and rear sides of the air duct 3, and exhaust holes are evenly formed in the top of the exhaust plates 4. The two arc-shaped plates 5 are respectively fixedly sleeved on the opposite sides of the two exhaust plates 4. Air guide holes communicating with the two exhaust plates 4 are formed in the front and rear sides of the air duct 3. The leak-proof sleeve 6 is fixedly sleeved on the outer side of the air duct 3, and the lower half of the middle section of the leak-proof cover is designed to be open. The exhaust plate 4 is inserted into the middle opening part of the leak-proof cover, and the arc-shaped plate 5 is slidably installed in the gap between the leak-proof cover and the air duct 3;

[0035] Connection sleeves 7 are connected to the inlet ends of the spray pipe 2 and the air duct 3. An adjusting component for adjusting the flow rate is arranged in the connection sleeve 7. A connection component is arranged between the two adjusting components. The inner diameter of the connection sleeve 7 gradually increases in the direction close to the spray pipe 2 or the air duct 3. A connection hole 11 is formed through the top of the connection sleeve 7;

[0036] An air inlet pipe 8 and a liquid inlet pipe 9 are inserted through one side of the spray tower 1, and the liquid inlet pipe 9 is located directly above the air inlet pipe 8. The ends of the liquid inlet pipe 9 and the air inlet pipe 8 located inside the spray tower 1 are respectively connected to the connection sleeves 7 on the spray pipe 2 and the air duct 3. A discharge pipe 10 is connected to the other side of the spray tower 1;

[0037] When spray-treating the tail gas of the kiln, as the tail gas is introduced into the air inlet pipe 8, the tail gas can push open the adjusting component in the corresponding connection sleeve 7 and enter the air duct 3. Subsequently, the tail gas can enter the two exhaust plates 4 through the air duct 3 and finally be evenly sprayed upward through the exhaust holes evenly arranged on the exhaust plates 4. When the sprayed tail gas moves upward, the alkaline solution introduced from the liquid inlet pipe 9 can push open the adjusting component in the corresponding connection pipe and enter the spray pipe 2, thereby realizing the spraying operation on the sprayed gas. During the process of the tail gas passing through the air inlet pipe 8, the adjusting component can automatically change the opening amplitude of the adjusting component according to the change in the tail gas introduction amount. With the adjustment of the adjusting component opposite to the air inlet pipe 8, this adjusting component can drive the adjusting component opposite to the liquid inlet pipe 9 through the connection component and make adjustments, thereby controlling the spraying amount of the alkaline solution, so that the alkaline solution can change synchronously according to the change in the tail gas introduction amount and avoid waste of excessive alkaline solution.

[0038] Such as Figures 2 to 6As shown, the adjusting component includes a baffle 12, a push rod 13, two fixing rings 14, a plurality of fixing rods 15 and a return spring 16. The baffle 12 is frustum-shaped, and the diameter of the baffle 12 is between the inner diameters of both ends of the connecting sleeve 7. In the initial state, the baffle 12 blocks one end of the inlet of the connecting sleeve 7. The push rod 13 at the top is vertically and fixedly connected to the center of the baffle 12 on the side close to the liquid inlet pipe 9, and the push rod 13 at the bottom is vertically and fixedly connected to the center of the baffle 12 on the side close to the air guide pipe 3. Both of the two fixing rings 14 are slidably sleeved on the push rod 13. A plurality of the fixing rods 15 are respectively fixedly connected to the outer sides of the two fixing rings 14, and the ends of the fixing rods 15 away from the fixing rings 14 are fixedly connected to the inner wall of the liquid inlet pipe 9 or the air guide pipe 3. The return spring 16 is sleeved on the push rod 13. The two ends of the return spring 16 on the top push rod 13 are respectively fixedly connected to the free end of the push rod 13 and the adjacent fixing ring 14, and the two ends of the return spring 16 on the bottom push rod 13 are respectively fixedly connected to the baffle 12 and the adjacent fixing ring 14;

[0039] The connecting component includes an L-shaped connecting rod 17, two movable rings 18, two retaining bars 19 and two connecting columns 20. The connecting rod 17 is fixedly connected between the two movable rings 18, and the top end of the connecting rod 17 is located in front of the top movable ring 18. Both of the two movable rings 18 are slidably sleeved on the two connecting sleeves 7. The two retaining bars 19 are respectively horizontally and fixedly connected to the top positions of the two movable rings 18. The bottom of the retaining bar 19 is in sliding fit with the surface of the connecting sleeve 7, and the width and length of the retaining bar 19 are both greater than the opening width and opening length of the connecting hole 11. The connecting column 20 is fixedly connected to the bottom of the retaining bar 19. The connecting column 20 is inserted into the connecting hole 11, and the bottom end of the connecting column 20 is fixedly connected to the top of the baffle 12;

[0040] When the alkaline solution and the tail gas enter the corresponding connecting sleeves 7 through the liquid inlet pipe 9 and the gas inlet pipe 8 respectively, the baffle 12 can move towards the outlet direction of the connecting sleeve 7 under the thrust of the solution or the airflow. During this process, the baffle 12 can drive the push rod 13 to move together, and the return spring 16 can be gradually compressed under the extrusion of the free end of the push rod 13 or the baffle 12. During the process of the tail gas entering the exhaust plate 4 through the gas inlet pipe 8, as the flow rate of the tail gas increases, the baffle 12 also moves towards the direction closer to the outlet end of the connecting sleeve 7 under the thrust of the tail gas. As the baffle 12 moves, since the baffle 12 is closer to the outlet end of the connecting sleeve 7, the inner diameter of the corresponding position of the connecting sleeve 7 is also larger, so that more tail gas can flow towards the outlet end of the connecting sleeve 7 through the gap between the baffle 12 and the inner wall of the connecting sleeve 7. When the flow rate of the tail gas decreases, the compressed return spring 16 can reset, pushing the baffle 12 to move towards the inlet end of the connecting sleeve 7, so that less tail gas can flow towards the outlet end of the connecting sleeve 7 through the gap between the baffle 12 and the inner wall of the connecting sleeve 7;

[0041] In addition, since a connecting component is connected between the two baffles 12, when the baffle 12 in the bottom connecting sleeve 7 moves towards the outlet end of the connecting sleeve 7 under the push of the airflow, the baffle 12 can drive the movable ring 18 to move along the outside of the connecting sleeve 7 through the connecting column 20. At the same time, the movable ring 18 at the top can move together under the drive of the connecting rod 17. As the top movable ring 18 moves, the movable ring 18 can drive the baffle 12 to move together through the connecting column 20 connected to it, so as to realize the control of the flow rate of the alkaline solution, so that the alkaline solution sprayed from the spray pipe 2 can change together according to the change of the flow rate of the tail gas introduced, avoiding waste of too much alkaline solution when the flow rate of the tail gas introduced decreases.

[0042] As Figures 5 to 8 shown, a movable ball 21 is rotatably installed in the exhaust hole of the exhaust plate 4. A through hole is formed through the top and bottom of the movable ball 21. A weight ring 22 is fixedly connected to the bottom edge position of the through hole. A conical protective cover 23 is arranged at the top of the through hole. A plurality of connecting rods 24 are fixedly connected between the protective cover 23 and the top of the movable ball 21. The weight of the weight ring 22 is greater than the sum of the weights of the movable ball 21, the protective cover 23 and the plurality of connecting rods 24;

[0043] When the tail gas of the kiln enters the exhaust plate 4, due to the existence of the movable balls 21, the movable balls 21 can drive the through holes of the movable balls 21 to be in a vertical state under the action of the counterweight rings 22. Therefore, when the tail gas enters the movable balls 21, the gas can be ejected upward, preventing the tail gas from spraying obliquely on the inner wall of the spray pipe 2, which may cause the alkaline solution to be unable to contact the tail gas. When the tail gas contacts the protective cover 23, the tail gas can be ejected uniformly along the bottom edge of the protective cover 23 under the blockage of the protective cover 23, thereby increasing the ejection area of the tail gas, enabling the nitrogen, sulfur, and nitrogen oxides in the tail gas to contact the alkaline solution more uniformly, improving the treatment effect of the alkaline solution on the tail gas. In addition, due to the existence of the protective cover 23, the protective cover 23 can also prevent the alkaline solution from entering the exhaust plate 4 through the through holes and avoid the retention of the alkaline solution in the exhaust plate 4.

[0044] As Figure 3 and Figure 4 shown, a retaining plate 25 is fixedly connected to one side of the baffle plate 12 close to the liquid inlet pipe 9 or the gas inlet pipe 8, and the diameter of the retaining plate 25 is smaller than the inner diameter of the gas inlet pipe 8 or the liquid inlet pipe 9;

[0045] By providing the retaining plate 25, when the airflow or the solution impacts on the retaining plate 25, the retaining plate 25 can play a certain agglomerating effect on the solution or the airflow, thereby enhancing the pushing effect of the airflow or the solution on the baffle plate 12, and further enabling the baffle plate 12 to move more smoothly inside the connecting sleeve 7 under the thrust of the water flow or the airflow.

[0046] As Figures 5 to 7 shown, a top plate 26 is fixedly connected to the bottom of the exhaust plate 4, and the height of the top plate 26 gradually decreases in the direction close to the gas inlet pipe 8. A top rod 27 is horizontally arranged at the bottom of the two top plates 26. An L-shaped rod 28 is fixedly connected to the middle position of the top rod 27. One end of the L-shaped rod 28 away from the top rod 27 is fixedly connected to the movable ring 18 at the bottom. The two ends of the top rod 27 are rotatably sleeved with bushing 29, and the two bushings 29 can always be in contact with the two top plates 26;

[0047] By providing the ejector rod 27, when the baffle 12 is pushed by the airflow to drive the movable ring 18 to move together through the connecting column 20, the movable ring 18 can drive the ejector rod 27 to move along the axis direction of the air duct 3 through the L-shaped rod 28. During this process, the bushing 29 on the ejector rod 27 can drive the two exhaust plates 4 to deflect upward with the air duct 3 as the axis through the upward pushing force on the top plate 26. And as the thrust of the airflow on the baffle 12 changes, the amplitude of the ejector rod 27 pushing the exhaust plates 4 to swing up and down through the top plate 26 also changes accordingly, so that the two exhaust plates 4 can be in a dynamic deflection state. And as the deflection angle of the exhaust plates 4 changes, the jet area corresponding to the exhaust holes at the top of the exhaust plates 4 also changes. The specific change is that the larger the upward deflection angle of the exhaust plates 4, the larger the jet area. Thus, when the intake volume of the kiln tail gas is larger, the exhaust plates 4 can disperse the kiln tail gas in a larger area through the jet holes on their surfaces, so that the alkaline solution sprayed by the spray pipe 2 can better neutralize the nitrogen, sulfur, and nitroxide gases in the kiln tail gas. When the intake volume of the kiln tail gas decreases, the deflection angle of the exhaust plates 4 is smaller, so the corresponding jet area is smaller, and at this time the sprayed amount of the corresponding alkaline solution also decreases accordingly, thus better meeting the spraying requirements of the alkaline solution at different intake volumes of the kiln tail gas.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
