Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically a multifunctional exhaust gas treatment scrubbing tower. Background Technology

[0002] A tail gas scrubbing tower is an environmental protection device used to treat harmful substances and particulate matter in industrial tail gas and waste gas. It typically consists of a tower body, a spray system, a packing layer, a demister, and a circulating water tank. Its working principle is as follows: waste gas enters the tower through the inlet at the bottom and, during its ascent, comes into full contact with the scrubbing liquid sprayed by the spray system. Pollutants in the waste gas are absorbed or removed by the scrubbing liquid. Further treatment by the packing layer effectively traps fine particulate matter and residual pollutants in the waste gas. Finally, the demister removes water droplets from the waste gas, and the purified gas is discharged from the top of the tower.

[0003] Utility model patent CN217613961U discloses a sulfuric acid tail gas scrubbing tower. The scrubbing tower includes a tower body. A waste gas inlet is connected to the lower left side of the tower body, and a filter screen is installed inside the waste gas inlet. Multiple packing layers are installed inside the tower body on the upper right side of the waste gas inlet. A spray assembly is installed inside the tower body directly above the packing layers. The spray assembly includes a spray pipe, which is fixedly installed above the packing layers by a positioning frame. A wet electrostatic precipitator is installed at the uppermost end of the spray assembly on the tower body. A cold water coil is installed inside the tower body directly above the wet electrostatic precipitator. An exhaust port is connected to the upper end of the tower body. The end of the spray pipe is connected to a dosing tank via a connecting pipe. When the exhaust gas reaches the packing layer, the alkaline solution in the dosing tank is pumped into the spray pipe through the connecting pipe to purify the exhaust gas. Then, the acid mist is adsorbed by a wet electrostatic precipitator, adsorbing the acidic impurities onto the anode of the wet electrostatic precipitator. At the same time, the anode of the wet electrostatic precipitator is sprayed with pure water to clean the wet electrostatic precipitator, which can greatly ensure the treatment effect of sulfuric acid tail gas.

[0004] Although the sulfuric acid tail gas scrubbing tower guarantees the treatment effect of sulfuric acid tail gas, the device still has the following problems in actual use: During the operation of the tail gas treatment scrubbing tower, although the tail gas will come into contact with the sprayed purification liquid as it rises in the tower, when the tail gas concentration increases, this contact is often insufficient to support a sufficient chemical reaction or absorption process between the two. High-concentration tail gas may quickly penetrate the purification liquid layer, causing some untreated tail gas to continue to rise, while the purification liquid falls directly to the bottom of the tower due to insufficient action. This phenomenon not only wastes purification resources, but also significantly reduces the overall purification efficiency and treatment effect of the tail gas. In view of this, we propose a multi-functional tail gas treatment scrubbing tower. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional exhaust gas treatment scrubbing tower to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multifunctional exhaust gas treatment scrubbing tower includes a tower body, an exhaust port installed at the top of the tower body, a hollow connecting compartment provided at the rear side of the tower body, an air inlet installed at the rear end face of the connecting compartment, a connecting pipe connected to the inner cavity of the tower body installed above the front face of the connecting compartment, a bent pipe inserted into the tower body installed below the front face of the connecting compartment, a hollow plate installed at the end of the bent pipe, the plate being located at the inner bottom of the tower body, and multiple air bubbles installed on the top of the plate.

[0009] A water pump is installed on the front side of the tower. An inlet pipe is installed at the inlet of the water pump, and a drain pipe is installed at the outlet of the water pump. Multiple horizontal pipes are installed on the outer wall of the drain pipe. The horizontal pipes pass into the tower body, and multiple nozzles are installed at the bottom of the outer wall of the horizontal pipes.

[0010] As a preferred technical solution of this utility model, a water inlet is installed at the top of the outer wall of the cooling box, and a drain outlet is installed at the bottom of the outer wall of the cooling box.

[0011] As a preferred technical solution of this utility model, two inspection ports are installed at the rear end of the outer wall of the tower body, and the inspection ports are connected to the inner cavity of the tower body.

[0012] As a preferred technical solution of this utility model, the air bubble stones are fixedly connected to the disc body by bolts, and multiple air bubble stones are distributed in a ring with equal spacing.

[0013] As a preferred technical solution of this utility model, the cooling box is provided with two supports, and the cooling box passes through the supports and is fixedly connected to the supports by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By designing a tower, cooling tank, and water pump, the exhaust gas is cooled in two ways: firstly, the flow channel facilitates cooling of the exhaust gas, preventing high-temperature exhaust gas from entering the tower and ensuring effective purification; secondly, the cooled exhaust gas enters the tower and the pan respectively through the inlet and bend. The exhaust gas entering the tower reacts with the purification liquid sprayed from the nozzles, while the exhaust gas entering the pan escapes as bubbles through multiple air bubbles into the solution at the bottom of the tower, where it reacts again. This dual treatment method ensures both overall purification efficiency and effectiveness while preventing the waste of purification liquid. Attached Figure Description

A cooling box 2 is provided at the rear. A flow channel 20 is provided inside the cooling box 2. A cooling jacket 21 for the flow of cooling water is provided on the outside of the flow channel 20. An air inlet pipe 22 connected to the flow channel 20 is installed at the rear end of the cooling box 2. An air inlet 14 is connected to the flow channel 20. A water pump 3 is provided at the front of the tower body 1. An inlet pipe 30 is installed at the inlet of the water pump 3. A drain pipe 31 is installed at the outlet of the water pump 3. Multiple horizontal pipes 32 are installed on the outer wall of the drain pipe 31. The horizontal pipes 32 penetrate into the tower body 1. Multiple nozzles 33 are also installed at the bottom of the outer wall of the horizontal pipes 32.

[0029] In this embodiment, a water inlet 23 is installed at the top of the outer wall of the cooling tank 2, and a drain outlet 24 is installed at the bottom of the outer wall of the cooling tank 2. The water inlet 23 and the drain outlet 24 facilitate the entry and exit of cooling water into the flow channel 20.

[0030] In this embodiment, two inspection ports 11 are installed at the rear end of the outer wall of the tower body 1, and the inspection ports 11 are connected to the inner cavity of the tower body 1. The inspection ports 11 facilitate the inspection and maintenance of nozzles 33 and other components inside the tower body 1.

[0031] In this embodiment, the air bubbles 18 are fixedly connected to the disc 17 by bolts, and multiple air bubbles 18 are distributed in a ring with equal spacing. The arrangement of multiple air bubbles 18 facilitates the uniform entry of exhaust gas into the purification liquid for reaction.

[0032] In this embodiment, two supports 25 are provided at the cooling box 2. The cooling box 2 passes through the supports 25 and is fixedly connected to the supports 25 by bolts. The supports 25 provide stable support and fixation for the cooling box 2.

[0033] In this embodiment, the connecting chamber 13 and the air inlet 14 are integrally formed structures, and both the connecting chamber 13 and the air inlet 14 are made of stainless steel. The integrally formed connecting chamber 13 and the air inlet 14 have better connection strength, while the stainless steel material gives the connecting chamber 13 and the air inlet 14 the advantage of corrosion resistance, ensuring the service life of the connecting chamber 13 and the air inlet 14.

The main function of the packing layer is to provide an increased gas-liquid contact area to promote sufficient contact and reaction between the exhaust gas and the spray liquid. The above are existing conventional technologies and will not be elaborated further here.

[0036] In practical use, the exhaust gas enters the flow channel 20 through the inlet pipe 22 and flows into the inlet 14 and the connecting chamber 13. At the same time, the cooling water flows in the cooling jacket 21. Under the action of the cooling water, the exhaust gas in the flow channel 20 can be cooled. The cooled exhaust gas enters the connecting pipe 15 and the bend pipe 16 through the inlet 14 and the connecting chamber 13. The exhaust gas enters the tower body 1 through the connecting pipe 15 and rises. During the rise, the exhaust gas reacts with the purification liquid sprayed by the nozzle 33. At the same time, the exhaust gas enters the plate 17 through the bend pipe 16 and enters the purification liquid at the bottom of the tower body 1 through multiple air bubbles 18 and reacts with the purification liquid. Then the exhaust gas leaves the purification liquid at the bottom of the tower body 1 and continues to rise. During the rise, the exhaust gas reacts again with the purification liquid sprayed by the nozzle 33. Finally, the purified exhaust gas is discharged to the outside through the exhaust port 10.
