Description

Technical Field

[0001] This utility model relates to the field of spray tower technology, and in particular to a multi-format chemical spray integrated tower. Background Technology

[0002] A spray tower is an environmentally friendly waste gas treatment device. When dusty or oily waste gas passes through the spray tower, a liquid medium, sometimes an alkaline solution and sometimes a sulfuric acid solution, is sprayed out from a suitable location inside the tower (depending on the design). If the waste gas is acidic, an alkaline solution is used to neutralize the acid; if it is alkaline, a sulfuric acid solution is used for absorption. Waste gas without acid or alkali but containing oil or dust can be treated by spraying with a circulating water solution. When the waste gas enters from the bottom of the tower, it comes into contact with the spray medium sprayed out by the spray tower. After contact, the waste gas or oil is coated with water droplets. The water droplets coating the pollutants collide again, increasing their surface area and gravity. Under the influence of gravity, the water droplets coating the pollutants fall to the bottom of the spray tower. Heavier pollutants sink to the bottom of the tower, while lighter pollutants float on the surface of the circulating water.

[0003] When treating high-concentration acid and alkali waste gas or waste gas with high oil and dust concentration, the treatment efficiency of a single-stage traditional spray tower device is insufficient. It is often necessary to use multiple spray towers in series. In order to increase the treatment efficiency, the concentration of the spray solution is also increased, which significantly increases the treatment cost. Utility Model Content

[0004] In order to reduce the cost of waste gas treatment and improve the treatment efficiency, this utility model provides a multi-format chemical spray integrated tower.

[0005] The integrated chemical spray tower with compartmentalized structure provided in this application adopts the following technical solution:

[0006] A multi-stage chemical spraying integrated tower includes a tower body and a water tank coaxially fixed at the bottom of the tower body. Three partition plates are arranged sequentially from top to bottom within the tower body, each partition plate equipped with a ventilation component. The three partition plates divide the internal space of the tower body into an air inlet zone, a primary spraying zone, a secondary spraying zone, and a final spraying zone from bottom to top. The air inlet zone is connected to an air inlet pipe for introducing waste gas. Spraying components and chemical recovery components are provided in the primary, secondary, and final spraying zones. The final spraying zone has an air outlet at its top. The water tank has four baffles that divide the internal space of the water tank into a first liquid storage chamber, a second liquid storage chamber, a third liquid storage chamber, and a fourth liquid storage chamber. The first liquid storage chamber is connected to the air inlet zone. The second, third, and fourth liquid storage chambers correspond one-to-one with the primary, secondary, and final spraying zones and are connected via corresponding spraying components. The concentration of the spray liquid in the first, second, third, and fourth liquid storage chambers gradually increases.

[0007] By adopting the above technical solution, the first liquid storage chamber and the air inlet area are connected. The exhaust gas first enters the first liquid storage chamber and the air inlet area and mixes with the spray liquid with the lowest concentration for pretreatment. Then, the exhaust gas enters the primary shower zone through the ventilation components on the bottom partition plate. The spray liquid in the second liquid storage chamber sprays the exhaust gas in the primary shower zone through the corresponding spray components. The exhaust gas that has undergone primary shower treatment enters the secondary shower zone through the ventilation components on the middle partition plate. The spray liquid in the third liquid storage chamber sprays the exhaust gas in the secondary shower zone through the corresponding spray components. The exhaust gas that has undergone secondary shower treatment passes through the partition plate located at the top. The ventilation components enter the final rinsing zone, and the spray liquid in the fourth storage chamber sprays the exhaust gas in the final rinsing zone through the corresponding spray components. The exhaust gas passes through pretreatment, primary rinsing, secondary rinsing and final rinsing in sequence. The concentration of the spray liquid gradually increases, thereby improving the treatment effect on the exhaust gas. The treated gas is discharged through the outlet. The chemical solutions in the primary rinsing zone, secondary rinsing zone and final rinsing zone are recycled and reused through the chemical solution recovery unit, thereby reducing costs and improving the chemical solution utilization rate. Moreover, the spraying in the primary rinsing zone, secondary rinsing zone and final rinsing zone is controlled individually by the corresponding spray components, which facilitates the spraying adjustment at different stages, thereby improving the efficiency of exhaust gas treatment.

[0008] Optionally, the air inlet pipe extends into the first liquid storage chamber and the air inlet area, and multiple downward-extending branch pipes are evenly distributed on the air inlet pipe, with the bottom ends of the multiple branch pipes extending below the liquid surface of the spray liquid located in the first liquid storage chamber and the air inlet area.

[0009] By adopting the above technical solution, the exhaust gas enters the first liquid storage chamber and the air inlet area through multiple branch pipes and mixes with the spray liquid to achieve the aeration effect, thereby improving the effect of exhaust gas pretreatment and thus improving the efficiency of exhaust gas treatment.

[0010] Optionally, the partition plate has coaxial ventilation holes, and the ventilation assembly is disposed at the ventilation holes. The ventilation assembly includes:

[0011] An air inlet cylinder is provided on the vent and extends upward. The air inlet cylinder, the partition plate and the inner wall of the tower form a collection space for collecting the sprayed liquid. The liquid recovery component is connected to the collection space. The air inlet cylinder is conical and open at the top. The diameter of the top of the air inlet cylinder is smaller than the diameter of the vent. The top of the air inlet cylinder has a connecting rod.

[0012] The diverter plate is conical and fixed on the connecting rod and located below the spray assembly. The bottom end of the diverter plate covers the top end of the air inlet cylinder. The diameter of the bottom end of the diverter plate is larger than the diameter of the top end of the air inlet cylinder. The diverter plate is used to guide the sprayed liquid to the collection space.

[0013] By adopting the above technical solution, taking the primary rinsing zone as an example, the exhaust gas escapes into the primary rinsing zone through the gap between the air inlet and the diverter plate after passing through the vent and air inlet. The spray assembly draws the spray liquid in the second liquid storage chamber and sprays it into the primary rinsing zone. The exhaust gas and spray liquid are mixed and treated. After primary rinsing, the exhaust gas rises and enters the secondary rinsing zone after passing through the vent on the middle partition plate. Meanwhile, the sprayed liquid in the primary rinsing zone falls down. The diverter plate guides and diverts the liquid, and the liquid slides down the inclined surface of the diverter plate into the collection space, thus preventing the liquid in the primary rinsing zone from falling back into the air inlet zone. The same principle applies to the secondary and final rinsing zones, thereby achieving continuous treatment of exhaust gas. However, liquids of different concentrations can be collected and reused separately, thereby improving the efficiency of exhaust gas treatment while reducing costs.

[0014] Optionally, the spray assembly includes:

[0015] A spray pump, wherein the spray pump is mounted on a water tank and the water inlet extends into the second liquid storage chamber;

[0016] A spray pipe is provided at the outlet end of the spray pump and extends into the initial spray zone. The spray pipe has multiple downward-facing spray heads located above the diverter plate.

[0017] By adopting the above technical solution, taking the primary shower zone as an example, the spray pump draws the spray liquid from the second storage chamber, and the spray liquid is sprayed out from multiple spray heads after passing through the spray pipe to treat the waste gas. The same applies to the secondary shower zone and the final shower zone. The waste gas is treated in stages by spray liquid of different concentrations, thereby improving the treatment effect.

[0018] Optionally, the initial spray zone is further provided with a functional component, which is a gas distributor or a packing layer, and the functional component is located between the spray pipe and the diversion plate.

[0019] By adopting the above technical solutions, the gas distributor or packing layer is used to increase the mixing efficiency of waste gas and spray liquid. Functional components are selected according to the composition of waste gas, thereby improving the waste gas treatment efficiency.

[0020] Optionally, the liquid recovery component is a return pipe. One end of the return pipe located in the initial rinsing zone is connected to the collection space and the other end is connected to the third liquid storage chamber. One end of the return pipe located in the secondary rinsing zone is connected to the collection space and the other end is connected to the fourth liquid storage chamber. One end of the return pipe located in the final rinsing zone is connected to the collection space and the other end is connected to the first liquid storage chamber.

[0021] By adopting the above technical solution, the spray liquid in the second storage chamber flows to the third storage chamber through the return pipe after spraying, and the spray liquid in the third storage chamber flows to the fourth storage chamber through the return pipe after spraying. The high-concentration spray liquid is replenished by the low-concentration spray liquid, and the spray liquid in the fourth storage chamber flows to the first storage chamber through the return pipe after spraying, thereby realizing the recycling of the spray liquid and reducing operating costs.

[0022] Optionally, a demister is provided at the top of the final shower zone, and the demister is located below the air outlet.

[0023] By adopting the above technical solution, the demister is used to separate liquid droplets carried in the gas, prevent liquid from entering the subsequent pipeline or fan, and ensure that the purified gas remains dry.

[0024] Optionally, the tower body is provided with an inspection port in the circumference.

[0025] By adopting the above technical solutions, the inspection port improves the convenience of tower inspection and maintenance.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The first liquid storage chamber and the air inlet zone are connected. The exhaust gas first enters the first liquid storage chamber and the air inlet zone and mixes with the lowest concentration of spray liquid for pretreatment. Then, the exhaust gas enters the primary shower zone through the ventilation components on the bottom partition plate. The spray liquid in the second liquid storage chamber sprays the exhaust gas in the primary shower zone through the corresponding spray components. The exhaust gas that has undergone primary shower treatment enters the secondary shower zone through the ventilation components on the middle partition plate. The spray liquid in the third liquid storage chamber sprays the exhaust gas in the secondary shower zone through the corresponding spray components. The exhaust gas that has undergone secondary shower treatment enters the secondary shower zone through the ventilation components on the top partition plate. Upon entering the final rinsing zone, the spray liquid in the fourth storage chamber sprays the exhaust gas in the final rinsing zone through the corresponding spray components. The exhaust gas sequentially passes through pretreatment, primary rinsing, secondary rinsing, and final rinsing, with the concentration of the spray liquid gradually increasing, thereby improving the treatment effect on the exhaust gas. The treated gas is discharged through the outlet. The chemical solutions in the primary rinsing zone, secondary rinsing zone, and final rinsing zone are recycled and reused through chemical solution recovery components, thereby reducing costs and improving chemical solution utilization. Furthermore, the spraying in the primary rinsing zone, secondary rinsing zone, and final rinsing zone is individually controlled by the corresponding spray components, facilitating spray adjustment at different stages and thus improving the efficiency of exhaust gas treatment.

[0028] 2. The continuous treatment of exhaust gas is achieved through the combination of the air inlet and the diverter plate, while the chemical solutions of different concentrations can be collected and reused separately, thereby improving the efficiency of exhaust gas treatment while reducing costs.

[0029] 3. After being sprayed, the spray liquid in the second storage chamber flows to the third storage chamber through the return pipe. After being sprayed, the spray liquid in the third storage chamber flows to the fourth storage chamber through the return pipe. After being sprayed, the spray liquid in the fourth storage chamber flows to the first storage chamber through the return pipe. By replenishing the high-concentration spray liquid with low-concentration spray liquid, the spray liquid is recycled, reducing operating costs. Attached Figure Description

When the detection values ​​of the four sensors are the same, the used spray liquid is discharged and replaced with new spray liquid.

[0051] The working principle of Embodiment 1 of this application:

[0052] The first liquid storage chamber 22 is connected to the air inlet zone 13. Exhaust gas first enters the first liquid storage chamber 22 and the air inlet zone 13, mixing with the lowest concentration of the spray liquid for pretreatment. Then, the exhaust gas escapes through the vent 121 on the lowest partition plate 12, the gap between the air inlet cylinder 31 and the diverter plate 32, and into the initial spray zone 14. The spray pump 41 draws the spray liquid from the second liquid storage chamber 23 and sprays it into the initial spray zone 14 through the spray head 421. The exhaust gas and spray liquid mix and enter the initial spray zone 14. In the process, the exhaust gas after the initial rinsing rises and enters the secondary rinsing zone 15 after passing through the vent 121 on the middle partition plate 12. Meanwhile, the sprayed liquid in the initial rinsing zone 14 falls down, and the diversion plate 32 guides and diverts the liquid. The liquid slides down the inclined surface of the diversion plate 32 into the collection space 33, thus preventing the liquid in the initial rinsing zone 14 from falling back into the air intake zone 13. The same applies to the secondary rinsing zone 15 and the final rinsing zone 16, thereby achieving continuous treatment of the exhaust gas.

[0053] After being sprayed, the spray liquid in the initial spray zone 14 flows to the third storage chamber 24 through the return pipe 51. After being sprayed in the secondary spray zone 15, the spray liquid in the third storage chamber 24 flows to the fourth storage chamber 25 through the return pipe 51. After being sprayed in the final spray zone 16, the spray liquid in the fourth storage chamber 25 flows to the first storage chamber 22 through the return pipe 51. By replenishing the high-concentration spray liquid with low-concentration spray liquid, the spray liquid is recycled, reducing operating costs.

[0054] The exhaust gas passes through pretreatment, primary rinsing, secondary rinsing, and final rinsing in sequence, with the concentration of the spray liquid gradually increasing, thereby improving the treatment effect on the exhaust gas. The treated gas is discharged through the exhaust port 161. The chemical solution in the primary rinsing zone 14, secondary rinsing zone 15, and final rinsing zone 16 is recycled and reused through the chemical solution recovery unit 5, thereby reducing costs and improving the utilization rate of the chemical solution. Furthermore, the spraying in the primary rinsing zone 14, secondary rinsing zone 15, and final rinsing zone 16 is individually controlled by the corresponding spraying components 4, which facilitates the adjustment of the spraying at different stages, thereby improving the efficiency of exhaust gas treatment.

[0055] Example 2

[0056] Different types of spraying liquid are placed in water tank 2 to remove different pollutants at different stages. When the spraying liquids placed in the first storage chamber 22, the second storage chamber 23, the third storage chamber 24 and the fourth storage chamber 25 are inconsistent, one end of the return pipe 51 located on the initial spraying zone 14 is connected to the collection space 33 and the other end is connected back to the second storage chamber 23. One end of the return pipe 51 located on the secondary spraying zone 15 is connected to the collection space 33 and the other end is connected back to the third storage chamber 24. One end of the return pipe 51 located on the final spraying zone 16 is connected to the collection space 33 and the other end is connected back to the fourth storage chamber 25, thereby avoiding the mixing of the spraying liquids.

[0057] The difference between the working principle of Embodiment 2 and Embodiment 1 is that the spray liquid in the first liquid storage chamber 22, the second liquid storage chamber 23, the third liquid storage chamber 24 and the fourth liquid storage chamber 25 is recycled after being sprayed through the return pipe 51.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
