Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization water washing towers, in particular to a water circulation treatment type sodium alkali process desulfurization water washing tower. Background Art

[0002] Sulfuric acid is an inorganic compound with the chemical formula H2SO4. It is the most important oxygen-containing acid of sulfur. Pure sulfuric acid is a colorless oily liquid that crystallizes at 10.36°C. It is usually produced in the form of aqueous solutions of various concentrations using a tower method and a contact method. During the production of sulfuric acid, a water scrubber is required to desulfurize the tail gas. However, in the existing sodium-alkali desulfurization water scrubber for sulfuric acid tail gas, the gas does not react fully in the solution tank, which affects the treatment effect, resulting in a decrease in the practicability of the overall mechanism, and the water in the water tower is not convenient for secondary use.

[0003] As the application number is 202121619190.7, the utility model discloses a sulfuric acid tail gas sodium alkali desulfurization water washing tower, including a bottom plate and a solution tank, the upper surface of the bottom plate is fixedly connected with the solution tank, the interior of the solution tank is equipped with a power mechanism, the outer wall of the motor output shaft is fixedly connected with a reciprocating screw, the outer wall of the reciprocating screw is movably connected with the solution tank, the outer wall of the reciprocating screw is equipped with a slide seat, and the internal gap of the slide seat is matched with a guide rod. The sulfuric acid tail gas sodium alkali desulfurization water washing tower, through the coordinated use of a motor, a reciprocating screw, a slide seat, a guide rod and a scraper, etc., through the stirring of the solution, ensures that the solution is fully in contact with the gas and the treatment effect is ensured, through the coordinated use of annular plates, conical buckets, bolts and mesh cylinders, etc., water enters the conical bucket along the annular plate, and then the water resources are recycled, and the treated tail gas is discharged through the top of the water tower. The setting of the mesh cylinder filters the solid impurities in the water, saving the use of water resources. However, during pretreatment, the desulfurization water washing tower cannot prevent the gas from directly entering the subsequent water tower, and cannot replace the water in the water tower at any time. It is also necessary to ensure that the device can continue to work during replacement, and it is not convenient to replace the filter inside the water tower.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a water circulation treatment type sodium alkali desulfurization water washing tower is proposed. Utility Model Content

At the same time, the sealing block 5 is sealed by the sealing strip 6, so that the gas can be prevented from directly entering the water bucket 9 without reaction. When there is liquid inside, the sealing block 5 is always parallel to the liquid surface under the action of buoyancy. When the sealing block 5 is completely higher than the through groove 7, the sealing block 5 is away from the sealing strip 6 at the same time, so that the external gas can enter the reaction box 1 to react and then enter the water bucket 9, thereby improving the reaction effect and filtering effect of the device;

[0024] Furthermore, the sealing strip 6 can prevent the sealing block 5 from being lifted up by the gas when the liquid level rises, thereby further preventing the gas from directly entering the water bucket 9 without reacting.

[0025] like Figure 3-Figure 4As shown, a sealing strip 6 is slidably provided inside the lower end of the sealing block 5, and four sealing strips 6 are evenly distributed around the center of the air inlet pipe 2, and the lower end of the sealing strip 6 is fixedly connected to the reaction box 1, and a through groove 7 is opened at the upper end of the sealing strip 6 through the air inlet pipe 2, and the lower end of the through groove 7 and the blocked upper end of the sealing strip 6 are located in the same plane, a guide tube 8 is fixedly provided on the other side of the reaction box 1, a water bucket 9 is fixedly provided on the other end of the guide tube 8, and a base 10 is fixedly provided on the other end of the water bucket 9, a spring 2 11 is fixedly provided on the lower end of the base 10, and a sealing plate 12 is fixedly provided on the upper end of the spring 2 11, and the sealing plate 12 is slidably connected to the base 10 at the same time, and a threaded groove 13 is opened on the upper end of the base 10.

Inside the water tank 18, a through hole 21 is opened around the lower end of the conduit 3 20, and four through holes 21 are evenly arranged around the center of the conduit 3 20. A sealing gasket 22 is slidably arranged inside the water tank 18 below the conduit 3 20, and the sealing gasket 22 is also slidably connected to the conduit 3 20. A bracket 23 is arranged at the lower end of the sealing gasket 22, and the bracket 23 is arranged in a cross shape. The bracket 23 is fixedly connected to the water tank 18, and a bolt 25 is meshed in the middle of the bracket 23. A drain pipe 24 is rotatably arranged around the bolt 25, and the bolt 25 penetrates the lower end of the drain pipe 24. The drain pipe 24 is also fixedly connected to the water tank 18, and the drain pipe 24 is arranged as a three-way pipe. The water in the bucket 9 During circulation, the water first passes through the filter element 16, and then enters the water tank 18 after being filtered by the filter element 16, thereby ensuring the effect of water washing and preventing the water pipe from being blocked. When the filter element 16 needs to be replaced, it is directly screwed down. As the filter element 16 is taken out, the sealing plate 12 first moves upward under the action of the spring 11 to seal the lower end of the base 10 to prevent the circulating water from directly entering the water tank 18 without being filtered. At the same time as the sealing plate 12 is drawn out, the air in the airbag 15 is discharged through the airway 14, so that the airbag 15 is retracted. This can further ensure the sealing effect of the filter element 16 and facilitate the placement and removal of the filter element 16, so that the device can be pushed for maintenance without suspending the device.When replacing the water in the water tank 18, the bolt 25 is directly screwed to drive the upper sealing gasket 22 to move up and down along the thread direction, so that the conducting direction of the conduit 3 20 can be changed.

[0027] Working principle: When using the water circulation treatment type sodium alkali desulfurization water washing tower, first, when there is no liquid in the reaction box 1, the sealing block 5 is always located at the lower end of the air inlet pipe 2 on the spring 4 and seals the through grooves 7 around it, and at the same time, the sealing block 5 is sealed by the sealing strip 6, so that the gas can be prevented from directly entering the water bucket 9 without reaction. When there is liquid inside, the sealing block 5 is always parallel to the liquid surface under the action of buoyancy. When the sealing block 5 is completely higher than the through groove 7, the sealing block 5 is away from the sealing strip 6 at the same time, so that the external gas can enter the reaction box 1 to react and then enter the water bucket 9, thereby improving the reaction effect and filtering effect of the device; secondly, when the water in the water bucket 9 is circulating, it will first pass through the filter element 16, and after being filtered by the filter element 16, it can enter the water tank 18, thereby ensuring the water washing effect, and then avoiding the water pipe from being blocked, and when the filter element 16 needs to be replaced, it can be directly unscrewed and replaced with the filter element. 16 is taken out, first the sealing plate 12 moves up under the action of the spring 2 11, and the lower end of the base 10 is sealed to prevent the circulating water from directly entering the water tank 18 without being filtered, and when the sealing plate 12 is withdrawn, the air in the airbag 15 is discharged through the airway 14, so that the airbag 15 is retracted, which can further ensure the sealing effect of the filter element 16, and can also facilitate the placement and removal of the filter element 16, so that the device can be promoted for maintenance without suspending the device; finally, when the water in the water tank 18 is replaced, the bolt 25 is directly screwed to drive the sealing gasket 22 at the upper end to move up and down along the thread direction, so that the conduction direction of the conduit 3 20 can be changed, and through the cooperation of the conduit 3 20, the sealing gasket 22 and the bolt 25, the conduit 3 20 has three different working states, so that the conduction direction of the conduit 3 20 can be flexibly changed according to different maintenance requirements, so as to facilitate better maintenance of the device seat.
