Description

Technical Field

[0001] This utility model relates to the field of flue gas desulfurization technology, specifically a flue gas desulfurization and dust removal device. Background Technology

[0002] Flue gas is a mixture of gases produced during the combustion, pyrolysis, or chemical reaction of substances. Its main components include harmless gases such as nitrogen, oxygen, and carbon dioxide, but it also contains a variety of pollutants. Among them, solid particulate matter such as dust and soot can reduce atmospheric visibility, sulfur dioxide and nitrogen oxides can easily cause acid rain, carbon monoxide is toxic, and volatile organic compounds can participate in photochemical reactions to form ozone pollution. In industrial production, transportation, and daily life, the emission and control of flue gas directly affect air quality and the ecological environment.

[0003] Flue gas desulfurization refers to the process of removing sulfur oxides such as sulfur dioxide from flue gas through physical, chemical, or combined physical and chemical methods. Its purpose is to reduce sulfur oxide emissions, prevent acid rain formation, reduce air pollution, and protect the ecological environment and human health. In the industrial field, flue gas desulfurization is a key technology for coal-fired power plants, steel plants, and other enterprises to control waste gas emissions and achieve environmental compliance.

[0004] Most existing flue gas desulfurization devices use filter bags to filter flue gas. However, these bags can become clogged when filtering dust particles of different diameters, resulting in poor desulfurization performance. Therefore, a flue gas desulfurization and dust removal device is proposed to address this problem. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A flue gas desulfurization and dust removal device according to this utility model includes a dust collection box; a valve is fixedly connected to the side wall of the dust collection box; an air inlet is fixedly connected to the side wall of the dust collection box; the air inlet extends to the bottom of the dust collection box; multiple exhaust ports are opened at the top of the air inlet; a suction pump is fixedly connected to the top of the dust collection box; an air outlet is fixedly connected to the side wall of the suction pump; an activated carbon adsorption layer is slidably connected to the inner side wall of the dust collection box; a glass fiber filter layer is slidably connected to the inner side wall of the dust collection box; the dust collection box... The bottom is fixedly connected to a first container. The flue gas first passes through the water in the first container to absorb pollutants, and then passes through two layers of filtration: an activated carbon adsorption layer and a glass fiber filter layer, for further desulfurization and dust removal. This achieves purification through physical water washing and filtration adsorption, ensuring that the flue gas is fully treated. Starting the air pump can extract the flue gas from the equipment, accelerate the flow speed of the flue gas inside the dust collector, reduce the slow processing caused by slow natural flow, and improve the overall purification efficiency. The activated carbon adsorption layer and the glass fiber filter layer are connected by a sliding connection, which can be directly pulled out for cleaning or replacement, reducing maintenance difficulty.

[0007] Preferably, a water pump is fixedly connected to the side wall of the dust collector; the water pump is positioned above the air inlet; a second container is fixedly connected to the side wall of the dust collector; a water pump pipe is fixedly connected to the side wall of the water pump; the water pump pipe is connected to the second container; a water spray pipe is fixedly connected to the inner side wall of the dust collector; the water spray pipe is positioned below the glass fiber filter layer; multiple sets of nozzles are fixedly connected to the bottom end of the water spray pipe; by adding a special desulfurization agent to the second container and starting the water pump, the agent is sprayed from the nozzles in a mist form to fully contact the flue gas, which can react with the sulfur oxides in the flue gas, further increasing water washing and filtration, improving desulfurization efficiency, and ensuring that the flue gas meets emission standards.

[0008] Preferably, a support frame is fixed to the side wall of the dust collector; a motor is fixed to the top of the support frame; and a stirring blade is fixed to the output end of the motor. By driving the stirring blade to rotate, the airflow in the first container is agitated by the motor, which can accelerate the contact frequency and mixing uniformity between flue gas and water flow, so that the sulfides in the flue gas can be fully dissolved in the water, thereby increasing the desulfurization reaction effect.

[0009] Preferably, a partition plate is fixed to the inner wall of the first container; the partition plate is located below the motor; the partition plate divides the rising flue gas into fine airflows, increases the contact area between the flue gas and the water flow inside the first container, and allows the pollutants in the flue gas to be more fully absorbed by the water, thereby increasing the efficiency of water washing desulfurization.

[0010] Preferably, a filter box is fixedly connected to the middle of the side wall of the air inlet; a primary filter layer is fixedly connected to the top of the filter box; and a cover plate is fixedly connected to the middle of the filter box. The cover plate performs preliminary filtration of the flue gas entering the equipment, intercepting large particulate impurities, dust and other pollutants in the flue gas, thereby increasing the treatment effect of the subsequent water washing of the first container, the activated carbon adsorption layer and the glass fiber filter layer.

[0011] Preferably, a fixed base is fixedly connected to the top of the dust collector; an inclined plate is rotatably connected to the middle of the fixed base; the inclined plate contacts the discharged desulfurized airflow, which can guide the airflow direction and reduce the impact of the airflow discharged from the outlet on the equipment around the dust collector.

[0012] The advantages of this utility model are:

[0013] 1. The flue gas desulfurization and dust removal device of this utility model first passes the flue gas through water in a first container to absorb pollutants, and then passes through two layers of filtration, namely an activated carbon adsorption layer and a glass fiber filter layer, to further desulfurize and remove dust. This achieves purification through physical water washing and filtration adsorption, ensuring that the flue gas is fully treated. Starting the air pump can extract the flue gas from the equipment, accelerate the flow speed of the flue gas inside the dust removal box, reduce the slow processing caused by slow natural flow, and improve the overall purification efficiency. The activated carbon adsorption layer and the glass fiber filter layer are slidably connected, which can be directly extracted for cleaning or replacement, reducing the difficulty of maintenance.

[0014] 2. The flue gas desulfurization and dust removal device of this utility model adds a special desulfurization agent to the second container. After the water pump is started, the agent is sprayed out in a mist from the nozzle and comes into full contact with the flue gas. It can react with the sulfur oxides in the flue gas, further increasing water washing and filtration, improving desulfurization efficiency, and ensuring that the flue gas meets emission standards.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a flue gas desulfurization and dust removal device includes a dust collection box 1; a valve 11 is fixedly connected to the side wall of the dust collection box 1; an air inlet 12 is fixedly connected to the side wall of the dust collection box 1; the air inlet 12 extends to the bottom of the dust collection box 1; multiple sets of exhaust ports 17 are opened at the top of the air inlet 12; a suction pump 13 is fixedly connected to the top of the dust collection box 1; an air outlet 14 is fixedly connected to the side wall of the suction pump 13; an activated carbon adsorption layer 15 is slidably connected to the inner side wall of the dust collection box 1; and a glass fiber filter is slidably connected to the inner side wall of the dust collection box 1. Filter layer 16; The bottom of the dust collector 1 is fixedly connected to a first container 18; During operation, the dust collector 1 is moved to a designated position, and the air inlet 12 is connected to the flue gas outlet, so that the flue gas enters the dust collector 1 from the middle of the air inlet 12. After the flue gas enters the dust collector 1, water can be added to the first container 18. At this time, the flue gas entering from the middle of the air inlet 12 can be discharged from multiple sets of exhaust ports 17, so that the flue gas comes into contact with the water in the middle of the first container 18. After the water absorbs the substances in the flue gas, the flue gas floats up and is filtered by the activated carbon adsorption layer 15 and the glass fiber filter. Layer 16 contacts the activated carbon adsorption layer 15 and the glass fiber filter layer 16, which further filter the flue gas and desulfurize it. During the treatment of the flue gas inside the dust collector 1, the suction pump 13 can be activated to draw the flue gas into the dust collector 1, accelerating the treatment effect. The treated flue gas can be discharged from the outlet 14. After prolonged use, the activated carbon adsorption layer 15 and the glass fiber filter layer 16 can be extracted for cleaning and continued use. The water inside the first container 18 can be discharged from the valve 11. The gas first passes through the water in the first container 18 to absorb pollutants, and then passes through two layers of filtration: the activated carbon adsorption layer 15 and the glass fiber filter layer 16, for further desulfurization and dust removal. This achieves purification through physical water washing and filtration adsorption, ensuring that the flue gas is fully treated. Starting the air pump 13 can extract the flue gas from the equipment, accelerate the flow speed of the flue gas inside the dust collector 1, reduce the slow processing caused by slow natural flow, and improve the overall purification efficiency. The activated carbon adsorption layer 15 and the glass fiber filter layer 16 are connected by a sliding connection, which can be directly extracted for cleaning or replacement, reducing maintenance difficulty.

[0025] like Figure 1 and Figure 5As shown, a water pump 2 is fixedly connected to the side wall of the dust collector 1; the water pump 2 is positioned above the air inlet 12; a second container 22 is fixedly connected to the side wall of the dust collector 1; a water pump pipe 21 is fixedly connected to the side wall of the water pump 2; the water pump pipe 21 is connected to the second container 22; a water spray pipe 23 is fixedly connected to the inner side wall of the dust collector 1; the water spray pipe 23 is positioned below the glass fiber filter layer 16; multiple sets of spray nozzles 24 are fixedly connected to the bottom end of the water spray pipe 23; during operation, when dust is collected... When treating the flue gas inside container 1, a special desulfurization agent is added to the second container 22. The water pump 2 is started so that the agent inside the second container 22 is sprayed out in a mist from the center of multiple nozzles 24 and comes into contact with the flue gas. By adding the special desulfurization agent to the second container 22 and starting the water pump 2, the agent is sprayed out in a mist from the nozzles 24 and comes into full contact with the flue gas. It can react with the sulfur oxides in the flue gas, further increase water washing and filtration, improve desulfurization efficiency, and ensure that the flue gas meets emission standards.

[0026] like Figures 1 to 2 As shown, a support frame 3 is fixedly connected to the side wall of the dust collector 1; a motor 31 is fixedly connected to the top of the support frame 3; and a stirring blade 32 is fixedly connected to the output end of the motor 31. During operation, when flue gas enters the dust collector 1 and is discharged from the exhaust port 17, the motor 31 can be started to drive the stirring blade 32 to rotate, stirring the airflow in the middle of the first container 18, allowing the flue gas to come into contact with the water flow inside the first container 18. By driving the stirring blade 32 to rotate and stir the airflow in the first container 18, the contact frequency and mixing uniformity of the flue gas and water flow can be accelerated, so that the sulfides in the flue gas can be fully dissolved in the water, thereby increasing the desulfurization reaction effect.

[0027] like Figures 1 to 2 As shown, a partition plate 4 is fixed to the inner wall of the first container 18; the partition plate 4 is located below the motor 31; during operation, as the flue gas rises from the first container 18, it can come into contact with the partition plate 4, which divides the flue gas into fine flue gas particles that come into contact with the water flow inside the first container 18; by dividing the rising flue gas into fine airflows through the partition plate 4, the contact area between the flue gas and the water flow inside the first container 18 is increased, allowing the pollutants in the flue gas to be more fully absorbed by the water, thereby increasing the efficiency of water washing desulfurization.

[0028] like Figures 1 to 3As shown, a filter box 5 is fixedly connected to the middle of the side wall of the air inlet 12; a primary filter layer 51 is fixedly connected to the top of the filter box 5; and a cover plate 52 is fixedly connected to the middle of the filter box 5. During operation, when the flue gas enters the dust collector 1 from the middle of the air inlet 12, the flue gas can pass through the middle of the filter box 5 and come into contact with the cover plate 52 inside the filter box 5. The cover plate 52 performs preliminary filtration of the flue gas. The cover plate 52 can be removed from the top of the filter box 5 to replace the primary filter layer 51. The cover plate 52 performs preliminary filtration of the flue gas entering the equipment, intercepting large particulate impurities, dust and other pollutants in the flue gas, thereby increasing the treatment effect of the subsequent water washing of the first container 18, the activated carbon adsorption layer 15 and the glass fiber filter layer 16.

[0029] like Figures 1 to 4 As shown, a fixed base 6 is fixedly connected to the top of the dust collector 1; an inclined plate 61 is rotatably connected to the middle of the fixed base 6; during operation, when the desulfurized flue gas is discharged from the air outlet 14, it can contact the inclined plate 61, and the inclined plate 61 contacts the airflow to guide the airflow; by the inclined plate 61 contacting the discharged desulfurized airflow, the direction of the airflow can be guided, reducing the impact of the airflow discharged from the air outlet 14 on the equipment around the dust collector 1.

[0030] Working principle: The dust collector 1 is moved to the designated position, and the air inlet 12 is connected to the flue gas outlet, allowing the flue gas to enter the dust collector 1 from the middle of the air inlet 12. After the flue gas enters the dust collector 1, water can be added to the first container 18. At this time, the flue gas entering from the middle of the air inlet 12 can be discharged from multiple sets of exhaust ports 17, allowing the flue gas to contact the water in the middle of the first container 18. After the water absorbs the substances in the flue gas, the flue gas floats up and contacts the activated carbon adsorption layer 15 and the glass fiber filter layer 16. The activated carbon adsorbs... The auxiliary layer 15 and the glass fiber filter layer 16 further filter the flue gas, performing desulfurization treatment. During the treatment of the flue gas inside the dust collector 1, the suction pump 13 can be activated to draw the flue gas into the dust collector 1, accelerating the treatment effect. The treated flue gas can be discharged from the outlet 14. After prolonged use, the activated carbon adsorption layer 15 and the glass fiber filter layer 16 can be extracted for cleaning and continued use. The water inside the first container 18 can be discharged from the valve 11. When treating the flue gas inside the dust collector 1, a special desulfurization agent is added to the second container 22. The water pump 2 is started, causing the agent inside the second container 22 to be sprayed into a mist from the center of multiple nozzles 24, contacting the flue gas. When the flue gas enters the dust collector 1 and is discharged from the exhaust port 17, the motor 31 can be started to drive the stirring blades 32 to rotate, agitating the airflow in the center of the first container 18, allowing the flue gas to contact the water flow inside the first container 18. As the flue gas rises from the first container 18, it can contact the partition plate 4. The separator 4 divides the flue gas into fine flue gas particles, which come into contact with the water flow inside the first container 18. When the flue gas enters the dust collector 1 from the middle of the air inlet 12, it can pass through the middle of the filter box 5 and come into contact with the cover plate 52 inside the filter box 5. The cover plate 52 performs preliminary filtration of the flue gas. The cover plate 52 can be removed and replaced by removing the primary filter layer 51 from the top of the filter box 5. When the desulfurized flue gas is discharged from the air outlet 14, it can come into contact with the inclined plate 61. The inclined plate 61 comes into contact with the airflow and guides the airflow.
