Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment, and more specifically, to a waste gas treatment device for coal combustion. Background Technology
[0002] The main components of the exhaust gas produced after coal combustion include carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen oxides (NOx). x The exhaust gases produced by coal combustion contain particulate matter (such as dust and coal slag) and trace amounts of heavy metals (such as mercury and lead). Therefore, before the exhaust gases are released, they need to be treated by exhaust gas treatment devices to reduce their adverse environmental impact.
[0003] Because coal combustion produces large particulate impurities, and existing waste gas treatment devices operate at high speeds, the waste gas rapidly enters the intake chamber and strongly impacts the filter screen, causing large particulate impurities to adhere to the filter screen surface and accelerating clogging. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a waste gas treatment device for coal combustion, which aims to solve the problem that large particulate impurities are easily adsorbed on the surface of the filter screen due to the excessively fast intake speed of waste gas in existing waste gas treatment devices.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a waste gas treatment device for coal combustion, including a treatment chamber, a base, a drain pipe, a control plate, and a funnel. The base is fixedly connected to the bottom of the treatment chamber, the drain pipe is fixedly connected to the bottom of the treatment chamber, the control plate is fixedly connected to the top front of the treatment chamber, and the funnel is fixedly connected to the top of the treatment chamber. The interior of the treatment chamber is filled with clean water, which can cool and slow down the waste gas entering the treatment chamber by filling the interior with clean water through the funnel. A filter assembly is provided above the base, and auxiliary components are provided on the outer wall of the filter assembly.
[0007] The filtration assembly includes an air pump, a three-way connector, an external connector, an output pipe, a fixing component, a fixing ring, a rotating shaft, impellers, and a filter screen. The air pump is fixedly connected to the outer wall of the treatment chamber, the three-way connector is fixedly connected to the output end of the air pump, the external connector is fixedly connected to the outer wall of the three-way connector, the output pipe is fixedly connected to the output end of the three-way connector, the fixing component is fixedly connected to the inner wall of the treatment chamber, the fixing ring is fixedly connected to the bottom of the inner wall of the treatment chamber, the rotating shaft is installed on the top of the fixing ring, the impellers are fixedly connected to the outer wall of the rotating shaft, and the filter screen is disposed inside the treatment chamber.
[0008] Preferably, the output end of the output tube passes through the processing chamber and extends to below the horizontal plane inside the processing chamber, and the fixing member is located on the outer wall of the output tube and is fixedly connected to the outer wall of the output tube.
[0009] By adopting the above technical solution, the output pipe can transport the waste gas into the liquid inside the treatment chamber, and the setting of the fixing component can stabilize the output pipe.
[0010] Preferably, the rotating shaft is rotatably connected to the fixed ring, and the blades are inclinedly disposed on the surface of the rotating shaft.
[0011] By adopting the above technical solution, when the exhaust gas enters the treatment chamber through the output pipe, it will impact the inclined surface of the blade, causing the blade to rotate under the impact force.
[0012] Preferably, the outer wall of the filter screen is slidably connected to the inner wall of the treatment chamber, and the filter screen is located above the horizontal plane inside the treatment chamber.
[0013] By adopting the above technical solution, the filter screen can slide inside the treatment chamber, filter the exhaust gas inside the treatment chamber, and clean the filter screen when water is added.
[0014] Preferably, the auxiliary components include a fixed rod, a limiting plate, a return spring, a spring push rod, a brush plate, a motor, and an eccentric wheel. The fixed rod is fixedly connected to the top of the filter screen, the limiting plate is fixedly connected to the inner wall of the treatment chamber, the return spring is fixedly connected to the bottom of the limiting plate, the spring push rod is fixedly connected to the top of the rotating shaft, the brush plate is located at the bottom of the filter screen, the motor is fixedly connected to the outer wall of the treatment chamber, and the eccentric wheel is located inside the treatment chamber.
[0015] Preferably, the fixing rod passes through the limiting plate and is slidably connected to the inner wall of the limiting plate through which it passes, and the bottom of the reset spring abuts against the top of the filter screen.

[0018] By adopting the above technical solution, when the rotating shaft rotates, the brush plate can be driven by the spring push rod to clean the bottom of the filter screen. When the motor starts, the output end can drive the eccentric wheel to rotate, so that the eccentric wheel collides with the filter screen, thereby further improving the cleaning effect on the surface of the filter screen.
[0019] The beneficial effects of this utility model are:
[0020] 1. By filling the treatment chamber with clean water, the clean water creates resistance to the exhaust gas as it enters through the output pipe, thus reducing its flow velocity. Simultaneously, the inclined blades generate impact force as the exhaust gas enters the chamber, pushing the blades and agitating the clean water. This ensures thorough mixing of the exhaust gas and water, allowing large particles in the exhaust gas to absorb moisture and fall to the bottom of the chamber under gravity. This solves the problem in existing exhaust gas treatment devices where large particles easily adhere to the filter surface due to excessively high exhaust gas intake speed.
[0021] 2. When the blades drive the shaft to rotate under the impact of exhaust gas, the shaft drives the brush plate to clean the filter plate through the spring push rod, which prevents the filter screen from being blocked by particles in the exhaust gas during long-term use and ensures the filter screen's filtration effect on the exhaust gas.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-5 A waste gas treatment device for coal combustion includes a treatment chamber 1, a base 2, a drain pipe 3, a control plate 4, and a funnel 5. The base 2 is fixedly connected to the bottom of the treatment chamber 1, the drain pipe 3 is fixedly connected to the bottom of the treatment chamber 1, the control plate 4 is fixedly connected to the front of the treatment chamber 1, and the funnel 5 is fixedly connected to the top of the treatment chamber 1. The interior of the treatment chamber 1 is filled with clean water. The funnel 5 can be used to fill the interior of the treatment chamber 1 with clean water, which can cool and slow down the waste gas entering the treatment chamber 1. A filter assembly 6 is provided above the base 2, and an auxiliary assembly 7 is provided on the outer wall of the filter assembly 6.
[0031] The filter assembly 6 includes an air pump 601, a three-way pipe 602, an external connecting pipe 603, an output pipe 604, a fixing member 605, a fixing ring 606, a rotating shaft 607, a paddle 608, and a filter screen 609. The air pump 601 is fixedly connected to the outer wall of the treatment chamber 1. The three-way pipe 602 is fixedly connected to the output end of the air pump 601. The external connecting pipe 603 is fixedly connected to the outer wall of the three-way pipe 602. The output pipe 604 is fixedly connected to the output end of the three-way pipe 602. The output end of the output pipe 604 penetrates the treatment chamber 1 and extends below the horizontal plane inside the treatment chamber 1. The output pipe 604 can transport waste gas into the liquid inside the treatment chamber 1. The fixing member 605 is fixedly connected to the inner wall of the treatment chamber 1. The fixing member 605 is located on the outer wall of the output pipe 604 and is fixedly connected to the outer wall of the output pipe 604. The setting of the fixing member 605 can stabilize the output pipe 604. A fixed ring 606 is fixedly connected to the bottom of the inner wall of the treatment chamber 1. A rotating shaft 607 is installed on the top of the fixed ring 606 and is rotatably connected to the fixed ring 606. A blade 608 is fixedly connected to the outer wall of the rotating shaft 607 and is inclinedly arranged on the surface of the rotating shaft 607. When the exhaust gas enters the interior of the treatment chamber 1 through the output pipe 604, it will impact the inclined surface of the blade 608, causing the blade 608 to rotate the rotating shaft 607 under the impact force. A filter screen 609 is arranged inside the treatment chamber 1. The outer wall of the filter screen 609 is slidably connected to the inner wall of the treatment chamber 1. The filter screen 609 is located above the horizontal plane inside the treatment chamber 1 and can slide inside the treatment chamber 1. The filter screen 609 can filter the exhaust gas inside the treatment chamber 1. At the same time, when adding clean water, the clean water can clean the filter screen 609.
[0032] By filling the interior of the treatment chamber 1 with clean water, the waste gas enters the treatment chamber 1 through the output pipe 604. The clean water creates resistance to the waste gas, thereby reducing its flow velocity. At the same time, since the blades 608 are inclined, the impact force generated when the waste gas enters the treatment chamber 1 will generate thrust on the blades 608, causing the blades 608 to stir the clean water inside the treatment chamber 1. This ensures that the waste gas and clean water are fully mixed, allowing large particulate impurities in the waste gas to fully absorb the water and fall to the bottom of the treatment chamber 1 under the influence of gravity. This solves the problem in existing waste gas treatment devices where large particulate impurities are easily adsorbed on the surface of the filter screen 609 due to the excessively fast waste gas intake velocity.
[0033] Auxiliary component 7 includes a fixing rod 701, a limiting plate 702, a return spring 703, a spring push rod 704, a brush plate 705, a motor 706, and an eccentric wheel 707. The fixing rod 701 is fixedly connected to the top of the filter screen 609. The limiting plate 702 is fixedly connected to the inner wall of the processing chamber 1. The fixing rod 701 passes through the limiting plate 702 and is slidably connected to the inner wall through which the limiting plate 702 passes. The fixing rod 701 and the limiting plate 702 cooperate to ensure the stability of the filter screen 609 during the filtration process. The return spring 703 is fixedly connected to the bottom of the limiting plate 702, and the bottom of the return spring 703 abuts against the top of the filter screen 609. The spring push rod 704 is fixedly connected to the top of the rotating shaft 607. The brush plate 705 is located at the top of the filter screen 609. The bottom of the filter screen 609 and the bottom of the brush plate 705 are fixedly connected to the top output end of the spring push rod 704. When the rotating shaft 607 rotates, the brush plate 705 can be driven by the spring push rod 704 to clean the bottom of the filter screen 609. The motor 706 is fixedly connected to the outer wall of the treatment chamber 1. The eccentric wheel 707 is set inside the treatment chamber 1. The output end of the motor 706 passes through the outer wall of the treatment chamber 1 and is fixedly connected to the outer wall of the eccentric wheel 707. The outer wall of the eccentric wheel 707 abuts against the top of the filter screen 609. When the motor 706 starts, it can drive the eccentric wheel 707 to rotate through the output end, so that the eccentric wheel 707 collides with the filter screen 609, thereby further improving the cleaning effect on the surface of the filter screen 609.
[0034] When the blade 608 drives the shaft 607 to rotate under the impact of the exhaust gas, the shaft 607 drives the brush plate 705 to clean the filter plate through the spring push rod 704, so as to prevent the filter screen 609 from being blocked by particles in the exhaust gas during long-term use, thus ensuring the filtration effect of the filter screen 609 on the exhaust gas.
[0035] The working principle of this coal combustion exhaust gas treatment device is as follows: Clean water is poured into the treatment chamber 1 through the funnel 5 and ground to the outlet end of the output pipe 604. Then, the external pipe 603 is connected to the exhaust gas source, and the air pump 601 is started. The exhaust gas in the exhaust gas source enters the three-way pipe 602 through the external pipe 603. After the air pump 601 starts, it compresses the outside air and delivers it to the inside of the three-way pipe 602. It also carries the exhaust gas inside the three-way pipe 602 into the treatment chamber 1 through the output pipe 604 and blows the inclined blade 608 to rotate. After the blade 608 rotates, it drives the clean water inside the treatment chamber 1 to rotate, which performs preliminary filtration on the exhaust gas delivered to the clean water. The exhaust gas passing through the clean water will gradually rise under the action of air pressure and be filtered through the filter screen 609 before being discharged through the funnel 5.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
