A spray absorption tower

Abstract

This utility model discloses a spray absorption tower, belonging to the technical field of spray absorption towers. It includes a tower body with a tower cover at the top, a rotating air intake assembly at the bottom of the tower's inner cavity, a drive assembly for driving the rotating air intake assembly at the bottom of the tower's outer surface, a spray hood fixedly mounted on the upper part of the tower's inner cavity, a packing disc mounted on the inner cavity above the spray hood via a mounting base, a pump body mounted on the bottom of the tower's outer wall, and a vertical pipe connected to the top outlet of the pump body. The vertical pipe is connected to the spray hood via an inlet pipe. This utility model features a unique swirling waste gas treatment method. A motor drives the air intake pipe, hollow support frame, and rotating ring to rotate, causing the waste gas to rise in a swirling state. Compared to the traditional linear upward method, this increases the residence time of the waste gas within the tower, making its movement path more complex and thus increasing the opportunity for contact between the waste gas and the absorbent liquid, creating more sufficient conditions for subsequent purification reactions.

Description

Technical Field

[0001] This utility model relates to the field of spray absorption tower technology, and specifically to a spray absorption tower. Background Technology

[0002] Spray absorption towers are a type of environmental protection equipment widely used in industrial waste gas treatment. Waste gas flows in from the bottom of the tower and comes into full contact with the absorbent liquid sprayed down from the top of the tower. The pollutants in the waste gas are captured by the absorbent liquid, thereby achieving the purpose of purifying the waste gas.

[0003] For example, Chinese Patent CN106984141 B discloses a spray absorption tower, which includes a tower body. The tower body is provided with a spray device inside. The tower body has an opening corresponding to the position of the spray device. A fixing plate is installed inside the opening. The spray device is located between a first exhaust pipe and a second exhaust pipe. The sides of the spray device are provided with a first mounting block and a second mounting block, which facilitates the disassembly of the spray device and makes it easy to assemble and disassemble the spray device.

[0004] While the aforementioned document addresses the issue of low gas treatment efficiency in existing spray towers, it still suffers from unsatisfactory purification effects. The exhaust gas enters the tower directly from a single exhaust pipe, resulting in a relatively short flow path within the tower and insufficient contact time with the absorbent liquid. Consequently, some harmful substances fail to be fully absorbed. Therefore, we provide a spray absorption tower to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a spray absorption tower that, through the cooperation of a rotating air intake component and a drive component, solves the problem in the prior art where a single exhaust pipe allows waste gas to enter the tower body, resulting in a relatively short flow path of the waste gas inside the tower and insufficient contact time with the absorption liquid, leading to unsatisfactory purification effects.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A spray absorption tower includes a tower body 1, a tower cover 8 at the top of the tower body 1, a rotating air intake assembly 2 at the bottom of the inner cavity of the tower body 1, a drive assembly 3 for driving the rotating air intake assembly 2 at the bottom of the outer side of the tower body 1, a spray hood 4 fixedly installed at the upper part of the inner cavity of the tower body 1, a packing disc 7 installed above the spray hood 4 in the inner cavity of the tower body 1 via a mounting base 6, a pump body 9 installed at the bottom of the outer wall of the tower body 1, and a vertical pipe 10 connected to the top outlet of the pump body 9, the vertical pipe 10 being connected to the spray hood 4 via an inlet pipe.

[0008] The rotating air intake assembly 2 includes a rotating ring 201, which is a hollow structure. The outer wall of the rotating ring 201 has a protrusion that is movably connected to an annular groove on the inner wall of the tower body 1. The inner wall of the rotating ring 201 is provided with a plurality of air outlet pipes 202. The bottom of the rotating ring 201 is fixedly connected to a "V"-shaped hollow support frame 203. The middle part of the hollow support frame 203 is fixedly connected to an air intake shell 204. The bottom of the air intake shell 204 is fixedly connected to an air intake pipe 205.

[0009] The drive assembly 3 includes a motor 301, a drive wheel 302, and a driven wheel 303. The motor 301 is fixedly installed on the outer bottom of the tower body 1. The drive wheel 302 is fixedly installed on the output shaft of the motor 301. The air inlet pipe 205 extends out of the bottom of the tower body 1 and the driven wheel 303 is fixedly installed on it. The driven wheel 303 and the drive wheel 302 mesh with each other.

[0010] An air receiving plate 11 is fixedly installed on the outer side wall at the bottom of the tower body 1. The air receiving plate 11 is connected to the air inlet pipe 205 through a connecting pipe. The air inlet pipe 205 is rotatably connected to the connecting pipe.

[0011] The tower body 1 has symmetrically fixed load-bearing frames 12 on both sides of its bottom, and the bottom of the load-bearing frames 12 has fixed support pads.

[0012] An annular cover 13 is fixedly installed on the inner wall of the tower body 1 between the spray hood 4 and the rotating air intake assembly 2. Several spray heads 14 are provided on the inner wall of the annular cover 13. The annular cover 13 is connected to the vertical pipe 10 through an inlet pipe.

[0013] The bottom of the tower body 1 is equipped with a drain pipe with a valve.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model has a unique swirling waste gas treatment method. The motor drives the air inlet pipe, hollow support frame and rotating ring to rotate, so that the waste gas rises in a swirling state. Compared with the traditional straight rising method, it can increase the residence time of the waste gas in the tower and make the movement path of the waste gas in the tower more complex, thereby increasing the chance of contact between the waste gas and the absorbent liquid, creating more sufficient conditions for the subsequent purification reaction.

[0016] 2. The pump body of this utility model draws in the absorbent liquid, and injects the absorbent liquid into the spray hood and the annular hood through the vertical pipe. Then, the absorbent liquid is sprayed out over a large area by the spray head on the spray hood and the upper spray head on the annular hood. This achieves large-area spraying of the absorbent liquid, and the large area of ​​absorbent liquid can fully contact the swirling and rising exhaust gas, ensuring that the pollutants in the exhaust gas can be more effectively captured and purified by the absorbent liquid, which greatly improves the removal capacity of pollutants in the exhaust gas.

[0026] Example 1

[0027] like Figures 1-4 As shown, this embodiment provides a spray absorption tower, including a tower body 1, a tower cover 8 at the top of the tower body 1, a rotating air intake assembly 2 at the bottom of the inner cavity of the tower body 1, a driving assembly 3 for driving the rotating air intake assembly 2 at the bottom of the outer side of the tower body 1, a spray hood 4 fixedly installed at the upper part of the inner cavity of the tower body 1, a packing disc 7 installed above the spray hood 4 in the inner cavity of the tower body 1 via a mounting base 6, a pump body 9 installed at the bottom of the outer wall of the tower body 1, and a vertical pipe 10 connected to the top outlet of the pump body 9, the vertical pipe 10 being connected to the spray hood 4 via an inlet pipe.

[0028] The rotating air intake assembly 2 includes a rotating ring 201, which is a hollow structure. The outer wall of the rotating ring 201 has a protrusion that is movably connected to an annular groove on the inner wall of the tower body 1. The inner wall of the rotating ring 201 is provided with several air outlet pipes 202. The bottom of the rotating ring 201 is fixedly connected to a "V"-shaped hollow support frame 203. An air intake shell 204 is fixedly connected to the upper part of the middle of the hollow support frame 203. An air intake pipe 205 is fixedly connected to the bottom of the air intake shell 204.

[0029] The drive assembly 3 includes a motor 301, a drive wheel 302, and a driven wheel 303. The motor 301 is fixedly installed on the outer bottom of the tower body 1. The drive wheel 302 is fixedly installed on the output shaft of the motor 301. The air inlet pipe 205 extends out of the bottom of the tower body 1 and the driven wheel 303 is fixedly installed on it. The driven wheel 303 and the drive wheel 302 mesh with each other.

[0030] An air receiving plate 11 is fixedly installed on the outer side wall at the bottom of the tower body 1. The air receiving plate 11 is connected to the air inlet pipe 205 through a connecting pipe. The air inlet pipe 205 is rotatably connected to the connecting pipe.

[0031] Specifically, exhaust gas is introduced into the intake pipe 205 through the air receiving plate 11. Simultaneously, the motor 301 is turned on. The output shaft of the motor 301 drives the drive wheel 302 to rotate. The drive wheel 302 drives the driven wheel 303 to rotate via a belt. The driven wheel 303 drives the intake pipe 205 to rotate, which in turn drives the hollow support frame 203 to rotate. The exhaust gas in the intake pipe 205 passes through the intake shell 204 into the inner cavity of the rotating ring 201 and is ejected through the outlet pipe 202. The hollow support frame 203 drives the rotating ring 201 to rotate, causing the exhaust gas to rise upwards in a swirling state. The intake pipe 205 is connected to the air receiving plate 11, allowing exhaust gas to continuously enter the rotating intake assembly 2 through the intake pipe 205.

[0032] Two load-bearing frames 12 are symmetrically fixed on both sides of the bottom of the tower body 1, and the bottom of each load-bearing frame 12 is fixed with a support pad with good anti-slip properties. The two load-bearing frames 12 can provide stable support for the bottom of the tower body 1, greatly improving the placement stability of the spray absorption tower.

[0033] An annular hood 13 is fixedly installed on the inner wall of the tower body 1 between the spray hood 4 and the rotating air intake assembly 2. Several spray heads 14 are installed on the inner wall of the annular hood 13. The annular hood 13 is connected to the vertical pipe 10 via an inlet pipe. The absorbent liquid enters the annular hood 13 simultaneously with the spray hood 4 and is sprayed out through the spray heads 14 on the inner wall of the annular hood 13, further improving the purification efficiency of the exhaust gas.

[0034] The bottom of the tower body 1 is equipped with a drain pipe with a valve.

[0035] A support plate is fixedly connected to the bottom of the inner cavity of the tower body 1, and a waterproof shell is fixedly connected to the bottom of the support plate. The bottom of the waterproof shell is fixedly connected to the bottom of the inner cavity of the tower body 1. The inner cavity of the support plate is movably connected to the surface of the air inlet pipe 205, which can improve the stability of the air inlet pipe 205 when it rotates. The waterproof shell can seal the connection gap between the air inlet pipe 205 and the bottom of the tower body 1. The sprayed waste liquid flows into the bottom of the tower body 1 and produces sediment. The staff regularly opens the valve to discharge the wastewater through the drain pipe. When it is necessary to disassemble the packing disc 7 for cleaning or replacement, the bolts on the first mounting plate and the second mounting plate are removed, and then the tower cover 8 can be removed to disassemble the packing disc 7.

[0036] The tower cover 8 is fixedly connected to both sides with a first mounting plate, and the top of both sides of the tower body 1 is fixedly connected to a second mounting plate. The first mounting plate and the second mounting plate are fixedly connected by bolts.

[0037] The working principle of this utility model is as follows: Waste gas is introduced into the inlet pipe 205 through the gas receiving plate 11. Simultaneously, the motor 301 and pump body 9 are turned on. The output shaft of the motor 301 drives the drive wheel 302 to rotate. The drive wheel 302 drives the driven wheel 303 to rotate via a belt. The driven wheel 303 drives the inlet pipe 205 to rotate. The inlet pipe 205 drives the hollow support frame 203 to rotate. The waste gas in the inlet pipe 205 enters the rotating ring through the inlet shell 204 and the hollow support frame 203. The exhaust gas is ejected from the inner cavity of 201 through the exhaust pipe 202. The hollow support frame 203 drives the rotating ring 201 to rotate, causing the exhaust gas to rise in a swirling state. The pump body 9 operates to draw in the absorbent liquid, and injects the absorbent liquid into the spray hood 4 and the annular hood 13 through the vertical pipe 10. The absorbent liquid is sprayed out over a large area through the spray head 5 on the spray hood 4 and the upper spray head 14 on the annular hood 13. The swirling exhaust gas comes into full contact with the absorbent liquid sprayed over a large area, and the pollutants in the exhaust gas are purified by the absorbent liquid.
