Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flue gas spraying, and more specifically, to a spray tower for flue gas treatment. Background Art
[0002] During the flue gas treatment process, a spray tower is needed to spray and purify the flue gas so that it meets the emission standards before being discharged. When the existing spray tower sprays the flue gas, generally a number of annular spray pipes are arranged in sequence from top to bottom in the spray tower. The flue gas passes through the spray pipes from bottom to top, and the liquid sprayed from the spray pipes treats the flue gas so that it meets the emission standards. However, the speed at which the flue gas passes through the spray pipes is fast, and the path of the flue gas in the spray tower is also short, which sometimes leads to incomplete purification and poor spraying effect. In addition, a drainage device is generally provided at the bottom of the spray tower to facilitate the discharge of the water sprayed in the spray tower to avoid the water level being too high to affect the air intake. However, if all the water in the spray tower is discharged, the flue gas entering the spray tower at this time will also be discharged from the drainage device at the bottom along with the sewage, which will cause flue gas leakage and affect the air quality.

[0016] Beneficial effects:
[0017] 1. The utility model is provided with a spray device, through which liquid medicine can be introduced through a spray pipe and sprayed out through a spray nozzle, and smoke enters the air intake section through an air intake pipe, flows upward, passes through the through hole on the baffle plate to enter above the baffle plate, and continues to spray the smoke through the spray pipe above, and the smoke continues to flow to the through hole of the baffle plate and passes through the through hole to enter above the baffle plate, thereby improving the spraying effect.
[0018] 2. The utility model is provided with a drainage device. When the water level in the collecting bucket rises, the buoyancy of the float increases.

An air intake pipe 26 is provided on the air intake section 4, and the lowest point of the air intake pipe 26 is higher than the highest point of the first water inlet pipe 10 and the second water inlet pipe 11.
[0031] In this embodiment, the air intake pipe 26 is connected to the smoke pipe, and the liquid inlet pipe 8 is connected to the external liquid medicine. The liquid medicine is first sprayed into the connecting section 3 through the spray pipe 6 and the spray nozzle 7 to make the water level higher than the highest point of the first water supply pipe 12 and the second water supply pipe 13. At this time, the buoyancy of the floating block 18 is less than the force of the spring 21. At this time, the smoke is passed from the air intake pipe 26 into the air intake section 4 and is treated by the liquid medicine sprayed by the spray pipe 6 under the lowest baffle 5. The smoke passes through the through hole 9 on the baffle 5 into the previous connecting section 3 and is sprayed through the spray pipe 6 in the previous connecting section 3. The smoke continues to rise to the exhaust hopper 2 and is discharged.
[0032] See also Figure 1-6 As an embodiment of the drainage device, the drainage device includes a fixed seat 16, a sealing seat 17, a floating block 18, a first connecting rod 19, a lifting frame 20, a spring 21 and a connecting nut 22. The top of the sealing seat 17 and the floating block 18 are fixedly connected by the first connecting rod 19. The bottom of the sealing seat 17 is provided with a second connecting rod 23, and the bottom of the second connecting rod 23 is provided with a threaded rod 24, which penetrates the lifting frame 20 and is threadedly connected with the connecting nut 22. The two ends of the spring 21 are respectively fixedly connected with the lifting frame 20 and the fixed seat 16. The fixed seat 16 is provided with a drainage hole 25, and the second connecting rod 23 is arranged in the drainage hole 25. A first drainage pipe 27 is provided at the bottom of the collecting bucket 1. The first drainage pipe 27 and the collecting bucket 1 are detachably connected by bolts. The fixed seat 16 is fixedly arranged in the first drainage pipe 27. The lower surface of the sealing seat 17 is provided with a first conical surface 28, and the drainage hole 25 is provided with a second conical surface 29 that matches the first conical surface 28. A guide rod 30 is provided on the upper surface of the lifting frame 20, and a guide hole 31 is provided on the lower surface of the fixing seat 16 to cooperate with the guide rod 30. A second drain pipe 32 is provided on one side of the first drain pipe 27, and an opening and closing valve 33 is provided at the second drain pipe 32.
[0033] More specifically, the spray liquid during the spraying process falls onto the baffle 5, and passes through the first water supply pipe 12 or the second water supply pipe 13 into the first connecting pipe 14 or the second connecting pipe 15, and enters the collecting bucket 1. At this time, the liquid level in the collecting bucket 1 rises. When the liquid level rises to the point where the buoyancy of the float 18 is greater than the force of the spring 21, the float 18 moves upward, driving the sealing seat 17 to leave the fixed seat 16, so that the water in the collecting bucket 1 is discharged from the first drain pipe 27. During this process, the spring 21 contracts. When the water level drops to the point where the buoyancy is less than the force of the spring 21, the spring 21 resets and drives the sealing seat 17 to reset, so that the water level is controlled to remain between the lowest point of the air intake pipe 26 and the highest point of the first water supply pipe 12, so as to prevent the smoke from being discharged from the first drain pipe 27, the first water supply pipe 12 or the second water supply pipe 13 due to the water level being too low.
[0034] In summary, when the overall equipment is in use or running: the air intake pipe 26 is connected to the smoke pipe, the liquid inlet pipe 8 is connected to the external liquid medicine, and the liquid medicine is first sprayed into the connecting section 3 through the spray pipe 6 and the spray nozzle 7 to make the water level higher than the highest point of the first water supply pipe 12 and the second water supply pipe 13. At this time, the buoyancy of the floating block 18 is less than the force of the spring 21. At this time, the smoke is passed from the air intake pipe 26 into the air intake section 4, and is treated by the liquid medicine sprayed by the spray pipe 6 under the lowest baffle 5. The smoke passes through the through hole 9 on the baffle 5 into the previous connecting section 3, and is sprayed through the spray pipe 6 in the previous connecting section 3. The smoke continues to rise to the exhaust hopper 2 and is discharged.
[0035] During the spraying process, the spray liquid falls onto the baffle 5, and passes through the first water diversion pipe 12 or the second water diversion pipe 13 into the first connecting pipe 14 or the second connecting pipe 15, and enters the collecting bucket 1. At this time, the liquid level in the collecting bucket 1 rises. When the liquid level rises to the point where the buoyancy of the float 18 is greater than the force of the spring 21, the float 18 moves upward, driving the sealing seat 17 to leave the fixed seat 16, so that the water in the collecting bucket 1 is discharged from the first drain pipe 27. In this process, the spring 21 contracts. When the water level drops to the point where the buoyancy is less than the force of the spring 21, the spring 21 resets and drives the sealing seat 17 to reset, so that the water level is controlled to remain between the lowest point of the air inlet pipe 26 and the highest point of the first water diversion pipe 12, so as to prevent the smoke from being discharged from the first drain pipe 27, the first water diversion pipe 12 or the second water diversion pipe 13 due to the water level being too low.
[0036] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
