Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a spray tower for waste gas treatment. Background Technology

[0002] Waste gas treatment, also known as waste gas purification, usually requires the use of spray towers. The principle of a waste gas spray tower is that the waste gas enters the spray tower and comes into contact with the spray liquid sprayed down from the top of the spray tower, turning the waste gas into waste liquid, which is then recycled and treated.

[0003] Existing technologies have the following problems:

[0004] Extensive searches revealed that Chinese Patent Publication No. CN212504332U discloses a spray tower for waste gas treatment, belonging to the technical field of waste gas treatment devices. The tower includes a tower body with a drain pipe at its lower end and a wastewater filter box at the other end. The wastewater filter box comprises a box body, a filter screen layer, a quartz sand layer, a neutralization layer, an adsorption resin layer, a water pump, and an activated carbon layer. This invention, by setting up a wastewater filter box, allows used wastewater from the tower to be discharged into the filter box through the drain pipe. The wastewater is filtered through three layers of filtration. By filtering the water to produce clean water and enabling its recycling, this invention significantly reduces costs and eliminates water waste. Through the installation of a sediment placement valve and a water injection valve, the sediment and repeatedly used wastewater in the tank can be drained by opening the sediment placement valve, and clean water can be injected into the tank through the water injection valve, thus achieving rapid replacement of the wastewater in the wastewater treatment tank. However, during the wastewater treatment process, some solid impurities are generated. If these impurities are not cleaned separately, they may clog the return water pipe, leading to problems with water circulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please refer to the following: Figure 1-4A spray tower for waste gas treatment includes a spray tower body 1. A collection frame 2 is fixedly installed on the lower surface of the spray tower body 1. A filter plate 3 is fixedly installed on the inner wall of the collection frame 2. A partition 4 is fixedly installed on the inner wall of the collection frame 2. A rotating shaft 8 is movably installed on the inner wall of the collection frame 2. A movable door 9 is fixedly installed on the outer surface of the rotating shaft 8. The partition 4, filter plate 3, and movable door 9 divide the interior of the collection frame 2 into a filter tank, a sewage tank, and a collection tank. A telescopic rod 5 is movably installed on the left inner wall of the filter tank. A push plate 6 is fixedly installed on the right end of the telescopic rod 5. A push column 7 is fixedly installed on the right surface of the push plate 6. A torsion spring 10 is sleeved on the outer surface of the rotating shaft 8. A collection box 11 is movably installed on the inner wall of the collection tank. A return water pipe 12 is connected to the outer surface of the sewage tank. A water tank 13 is fixedly installed on the upper surface of the spray tower body 1.

[0024] Specifically: In the process of using this utility model, firstly, exhaust gas is introduced into the interior of the spray tower body 1 through the air inlet pipe 20. When the exhaust gas enters, the spray head sprays water from the water tank 13, causing the water to come into contact with the exhaust gas in the spray tower body 1. After the water in contact with the exhaust gas becomes a liquid containing impurities, it falls to the bottom of the spray tower body 1 by its own gravity. At this time, the valve opens, and the liquid mixed with impurities falls into the interior of the outer frame through the air outlet pipe 21. When the waste liquid reaches the filter plate 3, the filter plate 3 filters the liquid, thereby filtering the impurities contained in the liquid to the top of the filter plate 3. The filtered liquid falls into the interior of the liquid tank and is transported back to the interior of the water tank 13 through the pump and the return water pipe 12, thus completing the water circulation. The filtered impurities remain above the filter plate 3. At this time, the telescopic rod 5 is activated, driving the push plate 6. Moving to the right, the push plate 6 drives the push column 7 to move to the right. During this movement, the push plate 6 pushes the impurities on the filter plate 3. When the push column 7 first contacts the movable door 9, it squeezes the movable door 9, causing it to rotate along the pivot 8. At this time, the torsion spring 10 rotates until the push plate 6 moves to the movable door 9, at which point the movable door 9 is in the open state. The push plate 6 pushes the impurities into the collection tank and then into the collection box 11. After this is completed, the telescopic rod 5 drives the push plate 6 and the push column 7 to retract. During the retraction process, the torsion spring 10, due to its own elasticity, drives the movable door 9 to gradually close until the push plate 6 and the push column 7 are completely away from the movable door 9. The movable door 9 then closes, and the impurities inside the collection box 11 are then manually disposed of.

[0025] In this embodiment: an air inlet pipe 20 is fixedly installed on the left surface of the spray tower body 1, an air outlet pipe 21 is fixedly installed on the lower surface of the spray tower body 1, and a support column 22 is fixedly installed on the lower surface of the spray tower body 1.

[0026] Specifically: Support column 22 supports the main body 1 of the spray tower, making it more stable.

[0027] In this implementation scheme: the two ends of the torsion spring 10 are fixedly connected to the front surface of the movable door 9 and the front inner wall of the outer frame, respectively; the inside of the return water pipe 12 is fixedly connected to the inside of the sewage tank; the lower surface of the push plate 6 is in contact with the upper surface of the filter plate 3; a pump is provided at the connection between the return water pipe 12 and the sewage tank; a spray head is provided on the outer surface of the water tank 13; the spray head is located inside the spray tower body 1; and the collection box 11 and the collection frame 2 are designed as drawers.

[0028] Specifically: The spray head technology is an existing structure, so it will not be described again. When the torsion spring 10 is in the normal state, the movable door 9 is in the closed state. The drawer design makes it convenient for workers to clean up impurities later.

[0029] In this embodiment: the interior of the air inlet pipe 20 and the interior of the air outlet pipe 21 are interconnected, and a valve is provided on the outer surface of the air outlet pipe 21.

[0030] Specifically: the valve controls the opening and closing of the air outlet pipe 21.

[0031] Working principle: This utility model uses the combined design of filter plate 3 and push plate 6 to filter the liquid and achieve solid-liquid separation. At the same time, the design of movable door 9 is to prevent the liquid from flowing into the collection box 11 along the filter plate 3 during filtration, thus avoiding liquid waste. Compared with related technologies, the spray tower for waste gas treatment provided by this utility model has the following beneficial effects: This design realizes the solid-liquid separation operation of the treated liquid, avoiding the situation where solids enter the return water pipe 12 and cause blockage of the return water pipe 12, thus affecting water circulation.

[0032] Example 2:

[0033] Please refer to the following: Figure 1-4 A pH meter 14 is fixedly installed on the front surface of the water tank 13. A medicine tank 15 is fixedly installed on the upper surface of the spray tower body 1. A medicine delivery pipe 16 is fixedly installed on the upper surface of the medicine tank 15. An electromagnetic valve 17 is provided on the outer surface of the medicine delivery pipe 16. A stirring structure 18 is provided inside the medicine tank 15. A controller 19 is fixedly installed on the outer surface of the spray tower body 1.

[0034] Specifically: When the filtered liquid enters the water tank 13 through the return water pipe 12, the pH detector will detect the acidity of the liquid inside the water tank 13 in real time. When the acidity of the liquid inside is lower than the required acidity, the controller 19 controls the solenoid valve 17 to open, and the acidic medicine in the medicine tank 15 is input into the water tank 13 through the medicine delivery pipe 16. At the same time, the stirring structure 18 is started to stir the medicine and water inside the water tank 13, so that they are fully mixed, and then sprayed into the interior of the spray tower body 1 through the spray head.

[0035] In this implementation scheme: pH meter 14 is electrically connected to controller 19, solenoid valve 17 is electrically connected to controller 19, stirring structure 18 is electrically connected to controller 19, and the interior of drug delivery pipe 16 is interconnected with the interior of drug delivery box and water tank 13.

[0036] Specifically: pH meter 14 is model BPH-220.

[0037] Working principle: This design uses a pH meter that can monitor the acidity and alkalinity of the water inside the water tank 13 in real time, thereby achieving the effect of controlling the acidity and alkalinity of the water inside the water tank 13. Compared with related technologies, the spray tower for waste gas treatment provided by this utility model has the following beneficial effects: This design achieves the effect of real-time detection of the liquid inside the water tank 13, avoiding uneven treatment effect or missed treatment due to the deviation of the liquid acidity and alkalinity.

[0038] The controller 19 is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0039] The selection of various devices varies depending on the specific circumstances, and should be based on the actual needs and various parameters, taking into account the function and desired effect of the equipment.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
