Description

Technical Field

[0001] This utility model relates to the field of exhaust gas absorption tower technology, specifically an exhaust gas absorption tower. Background Technology

[0002] A waste gas absorption tower is a device used to treat and purify waste gas. It is widely used in various fields such as power, pharmaceuticals, chemicals, electrical and electronic engineering, metallurgy, and brewing. However, existing waste gas absorption towers often suffer from poor reaction efficiency and incomplete reactions, resulting in the discharge of small amounts of polluting and toxic gases. Furthermore, long-term use makes it impossible to clean internal sediments, increasing maintenance costs.

[0003] As disclosed in the authorization announcement CN208660800U, a tail gas absorption tower is characterized by comprising an air inlet, a reverse nozzle, a gas-liquid separation tank, an electrostatic precipitator, a gas-sealed insulation box, a mist-collecting layer, a sedimentation anode tube, an exhaust stack, and a hot air inlet device. The reverse nozzle is connected to the air inlet and to the side of the gas-liquid separation tank. The top of the gas-liquid separation tank is equipped with a mist-collecting layer connected to the electrostatic precipitator. The electrostatic precipitator contains a sedimentation anode tube and has a gas-sealed insulation box at its top. The exhaust stack is connected to the top outlet of the electrostatic precipitator. This utility model can treat waste gas to meet the standards for sulfur dioxide and acid mist with a single device, requiring little space and suitable for the retrofitting of old plants where space is limited. It saves investment and is convenient to operate and manage. However, it does not solve the problems of poor reaction treatment effect and incomplete reaction in tail gas absorption towers, resulting in the exhaust gas containing small amounts of polluting and toxic gases, and the inability to clean internal sediments after long-term use, which increases maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a tail gas absorption tower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tail gas absorption tower includes an absorption tower body, a processing mechanism, and a collection mechanism. The processing mechanism is installed at the top of the interior of the absorption tower body, and the collection mechanism is fixedly installed at the bottom of the processing mechanism. The collection mechanism is located at the bottom of the absorption tower body, and a base is fixedly installed at the bottom of the absorption tower body. An inlet is opened at the top of the absorption tower body.

[0007] The treatment mechanism includes a treatment chamber, an annular toothed belt, and a main drive gear. The treatment chamber is fixedly installed inside the absorption tower body. An annular toothed belt is fixedly installed at the bottom of the treatment chamber. A main drive gear is fixedly installed in the center of the annular toothed belt. Three sets of auxiliary drive gears are installed on one side of the main drive gear, evenly distributed on it. The main drive gear and auxiliary drive gears are meshed and fixed. The other side of each auxiliary drive gear is meshed and fixed on the annular toothed belt. During operation, exhaust gas is discharged into the treatment chamber through an inlet at the top. A drive motor at the bottom drives the main drive gear and auxiliary drive gears at the top to rotate on the annular toothed belt, improving the stability of the internal structure during rotation.

[0008] Preferably, a connecting rod is fixedly connected above the main drive gear, a square plate is provided above the connecting rod, and a filter layer is fixedly provided above the square plate. By fixing the connecting rod and the square plate above, the internal exhaust gas flow is accelerated, and the filter layer provided above improves the processing efficiency and processing effect of the device.

[0009] Preferably, a pipe is fixedly connected above each of the auxiliary transmission gears, and a treatment liquid is fixedly installed inside the pipe. A spray nozzle is opened inward at the other end of each pipe, and a nozzle is fixedly installed above each spray nozzle. By continuously rotating, the nozzle above the pipe continuously sprays the treatment liquid, thereby achieving uniform and sufficient treatment of the exhaust gas.

[0010] Preferably, the collection mechanism includes a drive motor, a transmission rod, and an annular scraper. A collection plate is fixedly installed above the bottom of the absorption tower body. Holes are evenly distributed above the collection plate. A drive motor is fixedly installed at the center of the bottom of the collection plate. A transmission rod is connected to the output end of the drive motor. An annular scraper is fixedly installed on one side of the transmission rod. The top end of the transmission rod is fixedly connected to a column transmission gear. Through the collection mechanism, the continuously rotating annular scraper pushes the sediment above the holes, and it enters the collection chamber at the bottom through the holes, thus facilitating collection and processing.

[0011] Preferably, the annular scraper is centrally symmetrical on both sides, and the bottom end of the annular scraper is cut inward at an angle. With the annular scraper rotating continuously above, the centrally symmetrical design and the inward cut at the bottom end of the annular scraper facilitate pushing the sediment accumulated above into the collection chamber set at the bottom of the hole.

[0012] Preferably, a collection chamber is installed at the bottom of the collection plate, and a handle is fixedly installed on one side of the collection chamber, so that the collection chamber and the handle can be used to facilitate opening and collection.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This exhaust gas absorption tower, through its processing mechanism, allows exhaust gas to be discharged into the processing chamber through an inlet at the top. A drive motor at the bottom drives the main transmission gear and the secondary transmission gear at the top to mesh and rotate on a ring-shaped toothed belt, improving the stability of the internal structure during rotation. A connecting rod and pipe are fixedly connected at the top, thereby allowing the exhaust gas inside to be evenly sprayed with treatment liquid during rotation and accelerated through a continuously rotating square plate. The exhaust gas then passes through a filter layer at the top, thereby improving the treatment efficiency and effect of the device.

[0015] 2. This tail gas absorption tower, through a collection mechanism at the bottom, allows the precipitate after the treated liquid and tail gas have fully reacted to accumulate on the collection plate. The continuously rotating annular scraper at the top, with its centrally symmetrical design and inwardly slanted bottom, facilitates the pushing of the accumulated precipitate into the collection chamber at the bottom of the holes, thereby reducing the maintenance cost of the device and improving its practicality.

A base 4 is fixedly installed at the bottom of the absorption tower body 1, and an inlet 5 is opened at the top of the absorption tower body 1.

[0024] The treatment mechanism 2 includes a treatment chamber 201, an annular toothed belt 202, and a main drive gear 203. The treatment chamber 201 is fixedly installed inside the absorption tower body 1. An annular toothed belt 202 is fixedly installed at the bottom of the treatment chamber 201. A main drive gear 203 is fixedly installed in the center of the annular toothed belt 202. Three sets of auxiliary drive gears 204 are installed on one side of the main drive gear 203, evenly distributed on it. The main drive gear 203 and auxiliary drive gears 204 are meshed and fixed. The other side of each auxiliary drive gear 204 is meshed and fixed on the annular toothed belt 202. During use, exhaust gas is discharged into the treatment chamber 201 through the inlet 5 at the top. The drive motor 301 at the bottom drives the main drive gear 203 at the top to mesh with the auxiliary drive gears 204, rotating them on the annular toothed belt 202, thus improving the stability of the internal structure during rotation.

[0025] In this embodiment, preferably, a connecting rod 6 is fixedly connected above the main drive gear 203, a square plate 7 is provided above the connecting rod 6, and a filter layer 8 is fixedly provided above the square plate 7. By fixing the connecting rod 6 and the square plate 7 above, the internal exhaust gas flow is accelerated, and by using the filter layer 8 above, the processing efficiency and processing effect of the device are improved.

[0026] In this embodiment, preferably, a pipe 9 is fixedly connected above the secondary transmission gear 204, and a treatment liquid 10 is fixedly installed inside the pipe 9. A spray port 11 is opened inward at the other end of the pipe 9, and a nozzle 12 is fixedly installed above the spray port 11. By continuously rotating, the nozzle 12 above the pipe 9 continuously sprays the treatment liquid 10, thereby achieving uniform and sufficient treatment of the exhaust gas.

[0027] In this embodiment, preferably, the collection mechanism 3 includes a drive motor 301, a transmission rod 302, and an annular scraper 303. A collection plate 304 is fixedly installed above the bottom end of the absorption tower body 1. Holes 305 are evenly opened above the collection plate 304. A drive motor 301 is fixedly installed at the center of the bottom end of the collection plate 304. The output end of the drive motor 301 is connected to the transmission rod 302.

[0028] In this embodiment, preferably, the annular scraper 303 is centrally symmetrical on both sides, and the bottom end of the annular scraper 303 is cut inward at an angle.

During operation, tail gas is discharged into the processing chamber 201 through an inlet 5 at the top. A drive motor 301 at the bottom drives the main transmission gear 203 at the top to mesh with the secondary transmission gear 204, rotating them on an annular toothed belt 202. This improves the stability of the internal structure during rotation. A connecting rod 6 and a pipe 9 are fixedly connected at the top, allowing for the uniform spraying of the processing liquid 10 onto the internal tail gas. A continuously rotating square plate 7 further accelerates the flow of the tail gas. A filter layer 8 at the top further enhances the processing efficiency and effectiveness. A collection mechanism 3 at the bottom collects sediment from the reaction between the processing liquid 10 and the tail gas. This sediment accumulates on a collection plate 304, and a continuously rotating annular scraper 303, with its centrally symmetrical design and inwardly angled bottom, easily pushes the accumulated sediment into the collection chamber 13 at the bottom of the opening 305, thus reducing maintenance costs and improving practicality.
