Description

Technical Field

[0001] This utility model application relates to the field of desulfurization equipment technology, specifically a desulfurization equipment with waste gas recovery function. Background Technology

[0002] Desulfurization equipment is an environmental protection technology used to remove sulfur oxides from industrial waste gas. Its core purpose is to reduce the emission of acidic gases, prevent the formation of acid rain, and meet environmental regulations. The mainstream technology is the wet limestone-gypsum process, which uses an alkaline absorbent to contact the flue gas in a countercurrent manner and convert SO2 into stable sulfate or sulfite byproducts through a chemical reaction. The equipment usually includes key components such as an absorption tower, circulating pump, oxidation fan, and demister. Modern desulfurization systems can achieve a desulfurization efficiency of over 95%, making it a key link in air pollution control.

[0003] However, current desulfurization devices typically discharge saturated wet flue gas after desulfurization, with the temperature dropping to 45-55℃. When this type of flue gas is directly discharged into the atmosphere, the sudden drop in temperature causes gaseous water in the flue gas to condense and precipitate, forming white smoke. This results in the direct release of waste heat from this part of the flue gas into the atmosphere, and also causes the moisture in the flue gas to flow into the atmosphere, making it impossible to reuse this moisture for production purposes, thus resulting in waste. Summary of the Invention

[0004] To address the problem of waste heat from flue gas being directly emitted into the atmosphere, and the resulting moisture from the flue gas flowing into the atmosphere and being unable to be reused in production, thus causing waste, this invention provides a desulfurization device with waste gas recovery function to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A desulfurization device with waste gas recovery function includes a desulfurization tower body. An air inlet is located on one side of the desulfurization tower body, and an exhaust outlet is located on the other side. A dustproof baffle is fixed to the upper part of the desulfurization tower body. Four support columns are symmetrically fixed to the top surface of the dustproof baffle. Several condensate pipes are mounted on the four support columns. Each condensate pipe has a support frame at its bottom end, and each support frame is fixedly connected to a support column. The condensate pipes are interconnected. One side of the upper condensate pipe is connected to a water inlet. An inlet pipe is located on the outside of the desulfurization tower body and connected to the water inlet. The other side of the upper condensate pipe is connected to a drain outlet, which is connected to an external recovery water pipe. A recovery box is fixed to the bottom end of the lower support frame. A first recovery pipe and a second recovery pipe are respectively opened on both sides of the recovery box.

[0006] Furthermore, a servo motor is fixed on the top surface of the desulfurization tower body, the output end of the servo motor extends to below the dust baffle, the output end of the servo motor is rotatably connected to the dust baffle, and a dust removal plate is fixed on the output end of the servo motor.

[0007] Furthermore, the top surface of the dust removal plate is attached to the bottom surface of the dustproof baffle, and the shape of the dust removal plate is a triangular scraper.

[0008] Furthermore, the recycling bin is square in shape, and its length is greater than the length between any two adjacent support columns.

[0009] Furthermore, the recycling bin has an inclined surface in the middle that slopes toward the first recycling pipe and the second recycling pipe, and each of the first recycling pipe and the second recycling pipe is connected to an external recycling water pipe.

[0010] Furthermore, a dustproof net is fixed to the side of the exhaust port near the condensate pipe, and the exhaust port is located above the condensate pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a dustproof baffle is installed above the interior of the desulfurization tower body, and a support column is fixed inside the dustproof baffle. A condensate pipe is fixed on the dustproof baffle, so that when the flue gas enters above the dustproof baffle, cold water is injected into the condensate pipe through the inlet and then flows out through the outlet. This causes the high-temperature flue gas to condense in the condensate pipe and drip into the recovery tank. Finally, the condensate in the recovery tank is reinjected into the boiler through the first and second recovery pipes for use as production water. At the same time, the cold water that has absorbed heat is discharged through the outlet and then re-enters the boiler. This solves the problem of waste heat in the flue gas being directly emitted into the atmosphere, and also solves the problem of water in the flue gas flowing into the atmosphere, which cannot be reused for production and is thus wasted.

[0012] 2. In this utility model, by setting a servo motor on the top surface of the desulfurization tower body, the servo motor drives the dust removal plate to rotate, so that the dust removal plate scrapes off the dust attached to the bottom of the dust baffle. This solves the problem that a small amount of dust attached to the flue gas after desulfurization is easily discharged into the atmosphere through the exhaust port, and also avoids the problem of reduced flue gas flow caused by dust adhering to the bottom of the dust baffle.

Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A desulfurization device with waste gas recovery function includes a desulfurization tower body 1. An air inlet 2 is located on one side of the desulfurization tower body 1, and an exhaust outlet 3 is located on the other side. A dustproof baffle 4 is fixedly installed above the interior of the desulfurization tower body 1. Four support columns 5 are symmetrically fixed on the top surface of the dustproof baffle 4. Several condensate pipes 7 are installed on the four support columns 5. Each condensate pipe 7 has a support frame 6 at its bottom end, and each support frame 6 is fixedly connected to the support column 5. The several condensate pipes 7 are interconnected. One side of the upper condensate pipe 7 is connected to a water inlet 8. An inlet pipe is located on the outside of the desulfurization tower body 1 and connected to the water inlet 8. The other side of the upper condensate pipe 7 is connected to a drain outlet 9, which is connected to an external recovery water pipe. A recovery box 10 is fixed at the bottom of the lower support frame 6. A first recovery pipe 11 and a second recovery pipe 12 are respectively opened on both sides of the recovery box 10, allowing the flue gas to be condensed through the condensate pipes 7.

[0018] Specifically, a dustproof net is fixed on the side of the exhaust port 3 near the condensate pipe 7, and the exhaust port 3 is located above the condensate pipe 7 to prevent external dust from entering the desulfurization tower body 1.

[0019] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a servo motor 13 is fixed on the top surface of the desulfurization tower body 1. The output end of the servo motor 13 extends to the bottom of the dust baffle 4. The output end of the servo motor 13 is rotatably connected to the dust baffle 4. A cleaning plate 14 is fixed to the output end of the servo motor 13. The top surface of the cleaning plate 14 is in contact with the bottom surface of the dust baffle 4. The cleaning plate 14 is a triangular scraper, which allows the cleaning plate 14 to clean the dust at the bottom of the dust baffle 4.

[0020] Specifically, the recycling bin 10 is square in shape, and the length of the recycling bin 10 is greater than the length between every two adjacent support columns 5. The recycling bin 10 has an inclined surface in the middle of its interior that slopes toward the first recycling pipe 11 and the second recycling pipe 12. Each of the first recycling pipe 11 and the second recycling pipe 12 is connected to an external recycling water pipe, thereby increasing the speed at which the first recycling pipe 11 and the second recycling pipe 12 recycle condensate.

[0021] Working principle: When flue gas enters the desulfurization tower body 1 through inlet 2 and undergoes wet desulfurization treatment, the high-temperature flue gas rises above the dust baffle 4. At this time, cold water is injected into the condensate pipe 7 through inlet 8. When the water flows through the condensate pipe 7, it comes into contact with the high-temperature flue gas, causing the high-temperature flue gas to condense. Simultaneously, the condensate adhering to the condensate pipe 7 drips into the recovery tank 10 and flows back into the boiler through the first recovery pipe 11 and the second recovery pipe 12 for recycling. The cold water inside pipe 7 absorbs heat and is discharged through drain outlet 9. The water that has absorbed heat also flows into the boiler through the pipe for use. At the same time, the dust baffle 4 prevents dust in the high-temperature flue gas from entering the area above the dust baffle 4. When a lot of dust adheres to the bottom of the dust baffle 4, the servo motor 13 is started, which drives the cleaning plate 14 to rotate. The cleaning plate 14 then cleans the dust at the bottom of the dust baffle 4, preventing dust from blocking the flue gas flow path. The condensed flue gas at normal temperature is then discharged into the atmosphere through exhaust outlet 3.
