Description

Technical Field

[0001] This utility model relates to the field of smoke and mist removal technology, and in particular to a desulfurization flue gas water collection, dust removal, and mist removal device. Background Technology

[0002] Existing flue gas desulfurization methods can be classified into the following five types according to the type of desulfurizing agent: calcium method based on limestone, magnesium method based on magnesium oxide, sodium method based on sodium sulfide, ammonia method based on ammonia, and organic alkali method based on organic alkali.

[0003] The existing device uses a condenser to initially cool the flue gas in the exhaust pipe, which greatly reduces the heat in the flue gas and allows it to enter the desulfurization solution. Due to the significant reduction in heat, the evaporation of water in the desulfurization solution by the heat of the flue gas is effectively prevented, thus avoiding the condensation of solid substances and the clogging of the demister. However, the existing device is inconvenient to circulate the cooling water during use, which can easily lead to water waste and is quite inconvenient. Utility Model Content

[0027] like Figure 1 and Figure 2 As shown, this utility model provides a desulfurization flue gas water collection, dust removal, and demisting device, which includes: a flue gas tower 1, a water tank 9, and a purification tank 11. A condenser pipe 4 is connected to the outer surface of the flue gas tower 1. One end of the condenser pipe 4 penetrates the flue gas tower 1 and extends into its interior. A first drain pipe 8 is connected to the end of the condenser pipe 4. The other end of the first drain pipe 8 is connected to the purification tank 11. A water collection tank 7 is fixedly connected to the inner surface of the flue gas tower 1. A second drain pipe 10 is connected to one end of the water collection tank 7. The other end of the second drain pipe 10 penetrates the flue gas tower 1 and is connected to the purification tank 11. Both the water tank 9 and the purification tank 11 are located at the bottom of the chimney 1. The purification tank 11 is equipped with an activated carbon filter 12. The upper surface of the purification tank 11 is connected to a first water pump 13. The input end of the first water pump 13 is connected to a first water inlet pipe 14. The lower end of the first water inlet pipe 14 passes through the interior of the purification tank 11. The output end of the first water pump 13 is fixedly connected to a first water outlet pipe 15. The upper end of the first water outlet pipe 15 passes through the interior of the water tank 9. The left side of the water tank 9 is connected to a third water inlet pipe 25. The right end of the third water inlet pipe 25 passes through the interior of the condenser pipe 4.

[0028] The technical solution of this utility model is to set up a purification box 11. When the operator needs to circulate cooling water, after the flue gas treatment is completed, the water in the condenser pipe 4 and the water collection tank 7 is discharged into the purification box 11, purified and filtered by the activated carbon filter screen 12. The operator then controls the operation of the first water pump 13 to make the purified cooling water flow into the water tank 9 through the first water inlet pipe 14 and the first water outlet pipe 15. The purified water in the water tank 9 is then transported to the condenser pipe 4 through the third water inlet pipe 25, thereby completing the recycling of water resources.

[0029] Specifically, in this embodiment, the condenser pipe 4 is fixedly connected to the outer surface of the chimney tower 1, and the interior of the condenser pipe 4 is movably connected to the exhaust pipe 5. The interior of the chimney tower 1 is fixedly connected to the solution tank 2. The upper end of the exhaust pipe 5 passes through the condenser pipe 4 and the solution tank 2 in sequence and extends into the interior of the solution tank 2. The top end of the exhaust pipe 5 is connected to an L-shaped pipe 6, and one side of the solution tank 2 is connected to an inlet pipe 3. The upper end of the inlet pipe 3 passes through the chimney tower 1.

[0030] A second water pump 16 is fixedly connected to the upper surface of the water tank 9. A second water inlet pipe 17 is fixedly connected to the input end of the second water pump 16, and the lower end of the second water inlet pipe 17 passes through the inside of the water tank 9. A second water outlet pipe 18 is fixedly connected to the output end of the second water pump 16, and a booster compressor 19 is fixedly connected to the upper end of the second water outlet pipe 18. A dust collector 21 and a demister 22 are also connected to the inner surface of the chimney 1. Specifically, the dust collector 21 and the demister 22 are snapped onto the inner surface of the chimney 1. The booster compressor 19 is connected to the top of the chimney 1, and a bidirectional sprayer 20 is connected to the lower end of the booster compressor 19. The bidirectional sprayer 20 is positioned between the dust collector 21 and the demister 22.

[0031] By adopting the above technical solution, the desulfurization flue gas water collection, dust removal, and demisting device is equipped with a booster 19 and a second water pump 16. The second water pump 16 supplies water to the booster 19, which pressurizes the water flow. The water is then sprayed out through the bidirectional sprayer 20. The strong water pressure gives the water flow a strong impact force, causing the water flow to be sprayed towards the dust collector 21 and the demister 22. This can wash away the condensed scale, prevent the dust collector 21 and the demister 22 from being blocked, and improve the practicality of the device.

[0032] A water collection tank 23 is fixedly connected to the bottom of the outer surface of the chimney 1. The water collection tank 23 and the bidirectional sprayer 20 are correspondingly arranged. The lower end of the water collection tank 23 is connected to a third drain pipe 24, and the lower end of the third drain pipe 24 is connected to the purification tank 11. A water inlet 28 is provided on the upper surface of the water tank 9. A sewage pipe 26 is connected to one side of the purification tank 11, and a valve 27 is provided on the surface of the sewage pipe 26.

[0033] Working principle:

[0034] Limestone solution is added to solution tank 2 through inlet pipe 3. Then, booster compressor 19 and second water pump 16 are powered on. Second water pump 16 supplies water to condenser pipe 4 and booster compressor 19. At the same time, the water inlet of dust collector 21 and demister 22 obtains water through second outlet pipe 18. Flue gas enters the interior of flue gas tower 1 through exhaust pipe 5. When the flue gas is transmitted in exhaust pipe 5, exhaust pipe 5 is connected to the interior of condenser pipe 4. Water in condenser pipe 4 performs initial cooling of flue gas. Water in condenser pipe 4 evaporates and then condenses and drips into water collection tank 7. It flows into purification tank 11 through second drain pipe 10. After initial cooling, flue gas is transmitted to L-shaped pipe 6 and discharged through the outlet of L-shaped pipe 6, contacting the limestone solution inside solution tank 2 for desulfurization treatment. After desulfurization, the flue gas undergoes water collection, dust removal, and smoke removal treatment via dust collector 21 and demister 22 before being discharged into the air. Water is pressurized by booster 19 and sprayed out by bidirectional sprayer 20 to clean dust collector 21 and demister 22. The cleaned water, along with the water generated by dust collector 21 and demister 22, flows into water collection tank 23 and then into purification tank 11 through third drain pipe 24. After flue gas treatment is completed, the second water pump 16 is de-energized. After the exhaust pipe 5 cools down, all the water in the condenser pipe 4 is drained into purification tank 11. For the next use, the wastewater is purified by activated carbon filter 12. The operator controls the first water pump 13 to pump the purified cooling water through the first inlet pipe 14 and first outlet pipe 15 into water tank 9. The purified water in water tank 9 then flows through the third inlet pipe 25 into condenser pipe 4, thus completing the water resource recycling process. It should be noted that all electrical components in this device are electrically connected to an external power supply via an external control switch.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
