Description
Technical Field
[0001] The utility model relates to the technical field of chemical production, in particular to a desulfurization tower with a gas absorption mechanism. Background Art
[0002] A desulfurization tower is a chemical waste gas treatment device commonly used in the chemical production field to remove chemical waste gases such as sulfur dioxide and other gases from chemical gases. Currently, this type of device is relatively common in the chemical production field.
[0003] In the prior art, most desulfurization towers remove sulfur dioxide by spraying. Generally, the waste gas is introduced into the tower body, and then a spraying pipe is arranged in the tower body. The harmful gases in the waste gas are dissolved in water by spraying, and then the gas after waste gas treatment is discharged outside the tower body.
[0004] The above-mentioned desulfurization tower has some problems in absorbing sulfur dioxide and other gases in the waste gas by spraying. For example, this method requires continuous spraying operations through power facilities, and this process continuously consumes production costs, which is not conducive to the improvement of production costs. Moreover, the spraying operation is difficult to completely cover all the waste gas introduced into the tower body, resulting in poor treatment effects. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a desulfurization tower with a gas absorption mechanism to solve the technical problem that some existing desulfurization towers in the background art increase production costs by spraying water in the long run.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A desulfurization tower with a gas absorption mechanism includes a tower body. Two upper and lower opposite partitions are fixed in the tower body. A water storage cavity is formed between the tower body and the two partitions. A first through hole is opened on the upper partition. A guiding shell with a conical shell structure is fixed in the water storage cavity. A plurality of disks distributed up and down are fixed in the guiding shell. The circular cross-sectional shape of the disk at the corresponding position of the guiding shell is adapted. A plurality of second through holes are opened on each disk. A ventilation pipe is fixedly penetrated through the lower part of the tower body. The ventilation pipe penetrates into the guiding shell from the bottom of the guiding shell and passes through the disk at the uppermost position. An exhaust pipe is fixedly penetrated through the upper part of the tower body. A third through hole communicating with the water storage cavity is opened near the bottom of the guiding shell.
[0008] Working Principle:
[0009] When desulfurization treatment of waste gas is required, production personnel first inject clean water into the water storage cavity, and then introduce the external waste gas into the ventilation pipe. The waste gas in the ventilation pipe is injected into the water storage cavity at a certain air flow rate, and is injected at a position near the top of the injection guide shell. Then, the waste gas entering the guide shell will flow downward from the upper position of the water storage cavity under the restriction of the shape of the guide shell. During this process, the waste gas in the clean water of the water storage cavity will flow through the second through holes on each disc from top to bottom. And during the process of the waste gas flowing through each disc, it is disrupted by the second through holes on that disc. And because the waste gas in the ventilation pipe has a certain flow rate, a large number of bubbles will be formed during the process of entering the water storage cavity, and it will push the flow of the clean water in the water storage cavity, accelerating the flow of the waste gas in the water storage cavity, enabling the waste gas to fully contact the clean water in the water storage cavity, so that the harmful gas is dissolved in the clean water. Then the gas enters other areas of the water storage cavity except the guide shell through the third through holes, and finally flows upward in the tower body through the first through holes, and finally is discharged from the tower body through the exhaust pipe.
[0010] The beneficial effects of the present utility model are as follows:
[0011] During the use of the present utility model, production personnel pass the waste gas with a certain flow rate through the ventilation pipe into the area within the water storage cavity and inside the guide shell. Then, under the restriction of the shape of the guide shell, the waste gas flows through each of the above-mentioned discs from top to bottom, and has to flow through the second through holes on each disc from top to bottom. And during the process of the waste gas flowing through each disc, it is disrupted by the second through holes on that disc. And because the waste gas in the ventilation pipe has a certain flow rate, a large number of bubbles will be formed during the process of entering the water storage cavity, and it will push the flow of the clean water in the water storage cavity, accelerating the flow of the waste gas in the water storage cavity, enabling the waste gas to fully contact the clean water in the water storage cavity, so that the harmful gas is dissolved in the clean water. In the long run, this method replaces the spraying method for desulfurization, which is beneficial to reducing production costs.
[0012] And this process is beneficial to the full contact between the waste gas and the clean water in the water storage cavity, and is more beneficial to thoroughly removing the waste gas dissolved in water in the waste gas. While reducing production costs, it is beneficial to improve the operation efficiency. Description of the Drawings

Detailed implementation manners
[0016] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] As Figure 1 shown, a desulfurization tower with a gas absorption mechanism includes a tower body 1. Two upper and lower opposite partition plates 2 are fixed inside the tower body 1. A water storage cavity is formed between the tower body 1 and the two partition plates 2. A first through hole 3 is opened on one of the upper partition plates 2. A guide shell 4 with a conical shell structure is fixed in the water storage cavity. A plurality of vertically distributed discs 5 are fixed inside the guide shell 4. The circular cross-sectional shape of each disc 5 matches the corresponding position of the guide shell 4. A plurality of second through holes 6 are opened on each disc 5. A ventilation pipe 7 is fixedly penetrated through the lower part of the tower body 1. The ventilation pipe 7 penetrates upward from the bottom of the guide shell 4 into the guide shell 4 and passes through the disc 5 at the uppermost position. An exhaust pipe 8 is fixedly penetrated through the upper part of the tower body 1. A third through hole communicating with the water storage cavity is opened near the bottom of the guide shell 4. One end of a water pipe 17 that penetrates through the upper partition plate 2 and extends out of the tower body 1 is fixed on the partition plate 2 at the uppermost position. The other end of the water pipe 17 penetrates into the water storage cavity. Through the water pipe 17, clean water can be injected into the water storage cavity and the wastewater after treating the gas can be discharged, which can facilitate the timely replacement of clean water and ensure the efficiency of waste gas treatment.
[0018] Production personnel pass the waste gas with a certain flow rate through the ventilation pipe 7 through the area in the water storage cavity and inside the guide shell 4. Then, under the restriction of the shape of the guide shell 4, the waste gas flows through each of the above-mentioned discs 5 from top to bottom, and has to flow through the second through holes 6 on each disc 5 from top to bottom. And during the process that the waste gas flows through each disc 5, it is disrupted by the second through holes 6 on this disc 5. And because the waste gas in the ventilation pipe 7 has a certain flow rate, a large number of bubbles will be formed during the process of entering the water storage cavity, and the flow of the clean water in the water storage cavity will be promoted, accelerating the circulation of the waste gas in the water storage cavity, enabling the waste gas to fully contact the clean water in the water storage cavity, so as to dissolve the harmful gas in the clean water.
[0019] As Figure 1 and Figure 2As shown, a rotating shaft 9 that can rotate relative to the disc 5 is inserted through each disc 5. A plurality of force-receiving plates 10 with inclined downward plate surfaces are fixed to the upper part of each rotating shaft 9, and a first floating ball 11 with spikes on its surface is fixed to each rotating shaft 9. Since the waste gas introduced into the air pipe 7 has a certain flow rate, after the waste gas enters the water storage chamber, it will form a certain thrust or stirring force on the clear water in the water storage chamber while forming bubbles. At this time, the clear water mixed with bubbles may form a certain thrust on the force-receiving plate 10, and this part of the thrust is uncertain. The setting of this structure cannot ensure that the force-receiving plate 10 always drives the rotating shaft 9 to rotate under force. Its purpose is to form an external force on the force-receiving plate 10 in some cases, so that the force-receiving plate 10 can drive the rotating shaft 9 to rotate, and then the rotating shaft 9 drives the first floating ball 11 to rotate. The rotation of the first floating ball 11 can further pierce the bubbles in the water storage chamber, making the bubbles form more small bubbles, thereby further increasing the contact degree between the bubbles and the clear water and further improving the efficiency of dissolving in water. A second floating ball 12 with spikes on its surface is provided in the water storage chamber and between adjacent discs 5. When the bubbles pass between the two discs 5, they can be further pierced by the second floating ball 12, further increasing the contact degree between the waste gas and the clear water.
[0020] As Figure 1 and Figure 2 shown, a guide cylinder 13 fixed to the periphery of the guide housing 4 and coaxial with the guide housing 4 is provided in the water storage chamber. The bottom of the guide cylinder 13 is open, and the opening height at the bottom of the guide cylinder 13 is lower than the third through hole. After the bubbles formed by the waste gas pass through the lowermost disc 5, due to the natural phenomenon of the bubbles rising in the clear water, most of the bubbles will move upward to the top of the guide cylinder 13. Then, under the continuous discharge of the waste gas into the water storage chamber, the bubbles entering the guide cylinder 13 will move downward and flow into other areas outside the guide cylinder 13 through the gap between the bottom opening of the guide cylinder 13 and the guide housing 4, and finally are discharged from the water storage chamber through the first through hole 3. This setting further prolongs the flow path of the bubbles in the water storage chamber, further increases the contact degree between the waste gas and the clear water, and improves the waste gas treatment efficiency. A guide pipe 14 that extends upward near the top of the guide cylinder 13 is fixedly inserted through the third through hole. The top of the guide pipe 14 is a filter screen structure. The gas entering the guide housing 4 can ensure that all of it flows into the top of the guide cylinder 13 through the guide pipe 14 and the filter screen structure at its top. This method ensures that all the gas extends the flow path of the air flow, further ensuring the waste gas treatment efficiency.
[0021] As Figure 1 and Figure 2As shown, multiple split rings 15 distributed vertically are fixed to the outer side of the guide pipe 14. These multiple split rings 15 are all fixedly sleeved on the guide housing 4 in a manner adapted to the cross-section of the guide housing 4. The split ring 15 is also a filter mesh structure. The filter mesh-shaped split ring 15 is provided to further cut the bubbles when the bubbles pass through the split ring 15, so as to form more bubbles with smaller volumes and further improve the efficiency of waste gas treatment. Multiple third floating balls 16 with spikes on their surfaces are provided in the water storage cavity and between two adjacent split rings 15. The third floating balls 16 are also provided to further puncture the bubbles with a greater probability during the floating process of the third floating balls 16 in the clear water.
[0022] Working principle:
[0023] When desulfurization treatment of waste gas is required, production personnel first inject clear water into the water storage cavity, and then introduce the external waste gas into the ventilation pipe 7. The waste gas in the ventilation pipe 7 is injected into the water storage cavity at a certain air flow rate and is injected into the position near the top of the guide housing 4. Then, the waste gas entering the guide housing 4 will flow downward from the upper position of the water storage cavity under the limitation of the shape of the guide housing 4. During this process, the waste gas in the clear water in the water storage cavity will flow from top to bottom through the second through holes 6 on each disc 5. And during the process that the waste gas flows through each disc 5, it is disrupted by the second through holes 6 on this disc 5. And because the waste gas in the ventilation pipe 7 has a certain flow rate, a large number of bubbles will be formed during the process of entering the water storage cavity, and it will push the flow of the clear water in the water storage cavity, accelerating the flow of the waste gas in the water storage cavity, enabling the waste gas to fully contact the clear water in the water storage cavity, so as to dissolve the harmful gas in the clear water. Then the gas enters the guide pipe 14 outside the guide housing 4 in the water storage cavity through the third through holes, and then flows out of the guide pipe 14 and passes through multiple split rings 15 from top to bottom again. Then the bubbles flow out of the guide cylinder 13 through the gap between the bottom opening of the guide cylinder 13 and the guide housing 4, and finally flow upward to the upper part of the tower body 1 through the first through hole 3 and are finally discharged from the tower body 1 through the exhaust pipe 8.
