Description

Technical Field

[0001] The utility model relates to the technical field of air discharge gas washing appliances, in particular to an air discharge gas washing tower. Background Art

[0002] In industry, to remove certain gases from a mixed gas, a washing solution that can react with these gases is often used to react with the gases to be removed by reverse spraying, so as to remove these gases. A common washing tower, such as the SO2 absorption tower used in the wet desulfurization process, is to use downward spraying of limestone slurry or ammonia water to react with SO2 in the flue gas to generate gypsum or ammonium sulfate to achieve the purpose of removing SO2.

[0003] In order to increase the contact area with the washing liquid and improve the reaction efficiency, the existing air discharge gas washing tower pours the air discharge gas into the washing liquid and discharges it through the air outlet holes. However, the existing air discharge hole structure is simple. When the air outlet position is small, after the gas passes through the air outlet hole to form small bubbles, it will adhere to the side wall of the gas transmission elbow pipe to form large bubbles again, reducing the contact area between the air discharge gas and the washing liquid and lowering the reaction efficiency of the washing. Therefore, this application designs an air discharge gas washing tower to solve the above problems. Summary of the Utility Model

A transparent cover plate is provided at the end of the observation pipe. An air inlet port is opened at the lower end of the side wall of the washing cylinder. A gas transmission elbow pipe is provided inside the washing cylinder at the side end of the air inlet port.

[0006] Preferably, a lifting pump is provided at the side end of the washing cylinder on the top surface of the liquid storage tank. A delivery pipe is provided above the lifting pump. A suction pipe is provided below the lifting pump. The delivery pipe has two branches, and spray plates are provided at the ends of both branches.

[0007] Preferably, an adsorption core plate is provided in the middle of the spray plate. The adsorption core plate is a porous sponge material.

[0008] Preferably, corrugated plate packings are provided below the spray plates. Packing support plates for supporting the corrugated plate packings are provided below the corrugated plate packings. The corrugated plate packings are porous corrugated laminates.

[0009] Preferably, the bottom wall and the side wall at the end of the gas transmission elbow pipe are both provided with first air outlet holes. An attachment connecting plate is arranged on the upper part of the gas transmission elbow pipe. A suction groove is horizontally arranged in the middle of the attachment connecting plate. A plurality of second air outlet holes are equidistantly arranged at the top of the attachment connecting plate at the end of the suction groove.

[0010] Preferably, a liquid outlet pipe is arranged at the side end of the liquid storage tank. A butterfly valve for discharging the liquid material is arranged on the liquid outlet pipe. A detection cover plate is arranged on the top surface of the liquid storage tank. The detection cover plate is horizontally hinged on the top plate of the liquid storage tank.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, through the arrangement of the gas transmission elbow pipe, the vent gas can be first introduced into the washing liquid, so that the vent gas reacts and washes with a large amount of washing liquid first. Through the arrangement of the lift pump, the conveying pipe and the suction pipe, the washing liquid can be better transferred to the spray plate to spray the vent gas. Through the arrangement of the adsorption core plate, the vent gas can stay better to improve the washing efficiency. Through the arrangement of the corrugated packing, the contact area between the washing liquid and the vent gas can be better increased, thereby improving the washing efficiency of the washing tower. Through the arrangement of the first air outlet holes and the attachment connecting plate, when the gas outlet position is small, it can be avoided that after the gas passes through the first air outlet holes to form small bubbles and adheres to the side wall of the gas transmission elbow pipe to form large bubbles again, resulting in a reduction in the contact area between the vent gas and the washing liquid and a decrease in the reaction efficiency of the washing. Through the arrangement of the liquid outlet pipe and the butterfly valve, the washing liquid can be better poured out of the liquid storage tank to replace the new washing liquid. Through the arrangement of the detection cover plate, the bubbles formed by the attachment connecting plate can be better observed. BRIEF DESCRIPTION OF THE DRAWINGS

A washing cylinder 2 is provided on the top surface of the liquid storage tank 1. An observation tube 4 is provided on the side wall of the washing cylinder 2. A transparent cover plate is provided at the end of the observation tube 4. An air inlet port 3 is opened at the lower end of the side wall of the washing cylinder 2. An air delivery elbow pipe 9 is provided inside the washing cylinder 2 at the side end of the air inlet port 3. Through the setting of the air delivery elbow pipe 9, the air release gas can be first introduced into the washing liquid, so that the air release gas reacts and washes with a large amount of washing liquid first; a lift pump is provided at the side end of the washing cylinder 2 on the top surface of the liquid storage tank 1. A delivery pipe 5 is provided above the lift pump, and a suction pipe 10 is provided below the lift pump. The delivery pipe 5 has two branches, and spraying plates 12 are provided at the ends of the branches. Through the setting of the lift pump, the delivery pipe 5 and the suction pipe 10, the washing liquid can be better delivered to the spraying plates 12 to spray the air release gas; an adsorption core plate 13 is provided in the middle of the spraying plate 12. The adsorption core plate 13 is a porous sponge material. Through the setting of the adsorption core plate 13, the air release gas can be better retained, thereby improving the washing efficiency.

[0021] In the present utility model, corrugated plate packings 7 are provided at the lower parts of the spray plates 12, and packing support plates 8 for supporting the corrugated plate packings 7 are provided at the lower parts of the corrugated plate packings 7. The corrugated plate packings 7 are porous corrugated laminates. By providing the corrugated plate packings 7, the contact area between the washing liquid and the vent gas can be better increased, thereby improving the washing efficiency of the washing tower. First air outlet holes are formed in both the bottom wall and the side wall at the end of the gas transmission elbow pipe 9. An attachment connecting plate 11 is provided above the gas transmission elbow pipe 9. An adsorption groove 14 is horizontally formed in the middle of the attachment connecting plate 11. A plurality of second air outlet holes 15 are equidistantly formed at the top of the attachment connecting plate 11 at the end of the adsorption groove 14. By providing the first air outlet holes and the attachment connecting plate 11, in the case where the gas outlet position is small, it can be avoided that after the gas passes through the first air outlet holes to form small bubbles and adheres to the side wall of the gas transmission elbow pipe 9, large bubbles are re-formed, resulting in a reduction in the contact area between the vent gas and the washing liquid and a decrease in the reaction efficiency of the washing. A liquid outlet pipe is provided at the side end of the liquid storage tank 1, and a butterfly valve for discharging the liquid material is provided on the liquid outlet pipe. A detection cover plate 6 is provided on the top surface of the liquid storage tank 1. The detection cover plate 6 is horizontally hinged to the top plate of the liquid storage tank 1.

By providing the detection cover plate 6, the bubbles formed by the attachment connecting plate 11 can be better observed.

[0022] Working principle: When the present utility model is in use, first, power is connected to the lift pump. Then, washing liquid is added to the liquid storage tank 1. Subsequently, vent gas is introduced into the air inlet port 3. Then, the vent gas passes through the first air outlet holes through the gas transmission elbow pipe 9. Subsequently, the vent gas enters the adsorption groove 14 of the attachment connecting plate 11. The provision of the first air outlet holes and the attachment connecting plate 11 can avoid the situation where, when the gas outlet position is small, after the gas passes through the first air outlet holes to form small bubbles and adheres to the side wall of the gas transmission elbow pipe 9, large bubbles are re-formed, resulting in a reduction in the contact area between the vent gas and the washing liquid and a decrease in the washing efficiency. Subsequently, the vent gas passes through the second air outlet holes 15 until it floats out of the liquid surface. Then, the vent gas passes through the corrugated plate packings 7 attached with the washing liquid. Subsequently, the vent gas passes through the adsorption core plate 13 made of porous sponge. Then, the vent gas passes through the corrugated plate packings 7 and the adsorption core plate 13 again. Finally, the washing of the vent gas is completed. Thus, the use of the vent gas washing tower is completed.
