DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 As shown, a spray tower with an exhaust gas flow deceleration structure includes a tower body 1, a guide plate 4 and a flow deceleration component 7. A sedimentation tank 2 is arranged at the lower part of the tower body 1, and an air intake component 3 is arranged on one side of the sedimentation tank 2. The air intake component 3 includes an air intake pipe 301, a diverter pipe 302 and an annular pipe 303. The air intake pipe 301 is in an "L"-shaped structure, and the air intake pipe 301 passes through the side wall of the tower body 1. The bottom end of the air intake pipe 301 is connected with the diverter pipe 302, and the outer side of the diverter pipe 302 is connected with the annular pipe 303, and the diverter pipe 302 is in a "cross"-shaped structure; the air intake component 3 also includes an air outlet 304, the diverter pipe 302 and the annular pipe 303 are both located inside the sedimentation tank 2, and the lower side of the diverter pipe 302 and the inner side of the annular pipe 303 are both provided with an air outlet 304; a guide plate 4 is fixed at the middle and lower part of the interior of the tower body 1, and a demister plate 5 is installed at the upper part of the interior of the tower body 1;

[0023] The specific operation is as follows: the waste gas to be treated can enter the inside of the diverter pipe 302 and the annular pipe 303 through the air inlet pipe 301, so that the waste gas can be evenly discharged into the water body of the sedimentation tank 2 through the air outlet 304, thereby purifying and cooling the waste gas. At the same time, some impurities in the waste gas can be dissolved in water, and then the waste gas rises to facilitate subsequent spray purification. The setting of several guide plates 4 is convenient for extending the flow path of the waste gas inside the tower body 1, so that the waste gas flows in an "N" shape. The rising airflow after spraying can be discharged through the exhaust pipe 8 after defogger plate 5.

[0024] like Figure 1 and Figure 4 As shown, a circulating spray assembly 6 is installed on the outside of the sedimentation tank 2, and the circulating spray assembly 6 includes a water guide pipe 601, a water pump 602, a pump water pipe 603 and an outer ring pipe 604. The outer side of the sedimentation tank 2 is connected to the water pump 602 through the water guide pipe 601, and the upper side of the water pump 602 is connected to the pump water pipe 603, one end of the pump water pipe 603 is connected to the outer ring pipe 604, and the outer ring pipe 604 is installed on the outside of the tower body 1; the circulating spray assembly 6 also includes a connecting pipe 605, a spray pipe 606 and a nozzle 607, four outer ring pipes 604 are distributed, and the connecting pipes 605 are connected between the outer ring pipes 604, the inner side of the outer ring pipe 604 is connected to the spray pipe 606, and the nozzle 607 is installed equidistantly below the spray pipe 606, and the spray pipe 606 is located between the guide plates 4 inside the tower body 1;

[0025] The specific operation is as follows: the water in the sedimentation tank 2 can be pumped out to the interior of the top outer ring pipe 604 through the water guide pipe 601, the water pump 602, and the pump water pipe 603. The water in the top outer ring pipe 604 can flow into the interior of other outer ring pipes 604 through the connecting pipe 605. The outer ring pipe 604 and the spray pipe 606 are interconnected, so that the nozzle 607 under the spray pipe 606 can spray the exhaust gas flowing between the guide plates 4. The guide plates 4 are in an inclined structure, so that the water after spraying can flow downward in sequence and finally return to the interior of the sedimentation tank 2 for recycling.

[0026] like Figure 2-Figure 3As shown, a flow deceleration component 7 is installed in the middle of the tower body 1, and the flow deceleration component 7 includes a motor 701, a driving gear 702, a ring gear 703, a rotating shaft 704 and an air blowing fan 705. The lower side of the output shaft of the motor 701 is connected to the driving gear 702, and one side of the driving gear 702 is meshed with a ring gear 703, the ring gear 703 is rotatably connected to the upper wall of the tower body 1, and the inner side of the ring gear 703 is connected to the rotating shaft 704 through a fixed rod, and the air blowing fan 705 is installed on the lower outer side of the rotating shaft 704; the flow deceleration component 7 also includes a scraper 706, and two groups of scrapers 706 are connected to the upper outer side of the rotating shaft 704, and the two groups of scrapers 706 are located on the upper and lower sides of the defogger plate 5; the vertical center line of the rotating shaft 704 coincides with the vertical center line of the tower body 1, and the rotating shaft 704 is rotatably connected to the guide plate 4;

[0027] The specific operation is as follows: the motor 701 is used to drive the rotation of the driving gear 702, which can then drive the rotation of the ring gear 703 and the rotating shaft 704, so that the rotating shaft 704 drives multiple air blowing fans 705 to rotate to form a downward airflow, thereby slowing down and buffering the rising exhaust gas, extending the flow time of the exhaust gas inside the tower body 1, and promoting the full spraying of the exhaust gas. At the same time, the rotating shaft 704 can drive the scraper 706 to rotate, thereby promoting the sedimentation of droplets at the defogger plate 5.

[0028] In summary, if Figure 1-Figure 4 As shown, the spray tower with the exhaust gas flow deceleration structure, when in use, can first allow the exhaust gas to be treated to enter the inside of the diverter pipe 302 and the annular pipe 303 through the air inlet pipe 301, so that the exhaust gas can be evenly discharged into the water body of the sedimentation tank 2 through the air outlet 304, thereby purifying and cooling the exhaust gas, and at the same time, some impurities in the exhaust gas can be dissolved in the water, and then the exhaust gas rises. At this time, the setting of several guide plates 4 can extend the flow path of the exhaust gas inside the tower body 1, so that the exhaust gas flows in an "N" shape. In this process, the water in the sedimentation tank 2 can be pumped into the inside of the top outer ring pipe 604 through the water guide pipe 601, the water pump 602, and the pump water pipe 603, so that the nozzle 607 under the spray pipe 606 inside the multiple outer ring pipes 604 can spray the exhaust gas flowing between the guide plates 4. The guide plates 4 are in an inclined structure, so that the water body after spraying can flow downward in sequence and finally return to the inside of the sedimentation tank 2 for recycling;

[0029] During the spraying process, the motor 701 can drive the rotation of the driving gear 702, which can then drive the rotation of the ring gear 703 and the rotating shaft 704, so that the rotating shaft 704 drives multiple air fans 705 to rotate to form a downward airflow, thereby slowing down and buffering the rising exhaust gas, extending the flow time of the exhaust gas inside the tower body 1, and promoting sufficient spraying of the exhaust gas. Then, the rising airflow after spraying can be defogged by the defogger plate 5 and discharged through the exhaust pipe 8, thus completing the use of the spray tower with an exhaust gas flow deceleration structure.
