Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to an exhaust gas emission structure for heating boilers. Background Technology

[0002] Heating boilers are important thermal equipment in the field of civil engineering. According to the heating medium, they can be divided into steam boilers and hot water boilers. Hot water boilers are the mainstream choice for heating systems. Fuel types are further divided into four categories: coal-fired, gas-fired, oil-fired, and electric boilers. During the combustion process, heating boilers produce a large amount of exhaust gas, which contains a large number of harmful substances. It cannot be directly discharged into the air and needs to be purified by exhaust gas treatment equipment to meet emission standards.

[0003] However, traditional exhaust gas treatment equipment lacks consideration for temperature when treating exhaust gas. The exhaust gas emitted by heating boilers is often accompanied by high temperature. If it is not treated, it may damage the purification materials in the purification device. Large particles in the exhaust gas may even clog the pores of the filter material and affect its service life.

[0004] For example, when exhaust gas that has not been cooled is directly subjected to adsorption treatment, the high-temperature exhaust gas comes into direct contact with materials such as activated carbon and filter bags in the purification material, which will cause the surface temperature of the material to rise. Large particles in the exhaust gas may even clog the filter pores, rendering the filter material unusable. Utility Model Content

[0005] This utility model discloses a tail gas emission structure for heating boilers, aiming to solve the technical problem that traditional tail gas treatment equipment lacks temperature control during tail gas treatment, which leads to damage to the purification materials in the purification device, and large particles in the tail gas may even clog the pores of the filter material, affecting its service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tail gas emission structure for a heating boiler includes a base and a water tank fixed to the top left side thereon. A connecting pipe is fixedly connected to the top of the water tank, and a purification cabinet is fixedly connected to the other end of the connecting pipe. An exhaust port is fixedly connected to the top of the purification cabinet. The structure also includes: a cooling mechanism: the cooling mechanism includes an air intake hood fixedly connected to the left side of the water tank. A fan blade is disposed inside the air intake hood, and a transmission pipe is fixedly connected to the top of the air intake hood. A gear is fixedly connected to the bottom right end of the fan blade, and a rotating shaft is fixedly connected to the right side of the gear. A stirring plate is fixedly connected to the surface of the rotating shaft, and connection ports are provided on both the front and rear sides of the stirring plate; and a purification mechanism: the purification mechanism is slidably connected inside the purification cabinet.

[0008] In this solution, the exhaust gas is cooled by a cooling device. When the high-temperature, high-pressure exhaust gas is discharged into the intake hood, the airflow drives the fan blades to rotate. Through the transmission of gears and shafts, the stirring plate is stirred in the water. At the same time, the exhaust gas entering the intake hood enters the water tank through the transmission pipe and is discharged into the water in the tank. The stirring plate increases the water flow and breaks up large air bubbles in the water, thereby efficiently absorbing the temperature in the exhaust gas and adsorbing large particles. The cooled exhaust gas is discharged into the purification cabinet through the connecting pipe for further purification treatment.

[0009] In a preferred embodiment, the purification mechanism includes a purification box slidably connected inside the purification cabinet. A handle is fixedly connected to the front side of the purification box. A sliding groove is provided inside the purification box, and a placement plate slides inside the sliding groove. A fixing plate is rotatably connected to the top of the placement plate. There are four placement plates, which are equidistantly slidably connected in the sliding groove. A cavity for placing purification materials is provided in the placement plate. A buckle corresponding to the placement plate is provided on the right end of the fixing plate. Strip-shaped ventilation holes are opened on the surfaces of the placement plate and the fixing plate.

[0010] The purification system effectively purifies exhaust gases layer by layer, facilitating the replacement of the purification materials. As the exhaust gases diffuse upwards from the bottom of the purification cabinet, they come into contact with the layers of filter materials inside the placement plate, absorbing harmful substances and thus meeting emission standards before being discharged from the exhaust port. After long-term purification, the removable design of the purification box and placement plate allows for easy replacement of the purification materials, ensuring the purification effect of the system.

[0011] As described above, a tail gas emission structure for a heating boiler includes a base and a water tank fixed to its top left side. A connecting pipe is fixedly connected to the top of the water tank, and a purification cabinet is fixedly connected to the other end of the connecting pipe. An exhaust port is fixedly connected to the top of the purification cabinet. The structure also includes: a cooling mechanism: the cooling mechanism includes an air inlet hood fixedly connected to the left side of the water tank. A fan blade is disposed inside the air inlet hood, and a transmission pipe is fixedly connected to the top of the air inlet hood. A gear is fixedly connected to the bottom right end of the fan blade, and a rotating shaft is fixedly connected to the right side of the gear. A stirring plate is fixedly connected to the surface of the rotating shaft, and connection ports are provided on both the front and rear sides of the stirring plate; and a purification mechanism: the purification mechanism is slidably connected inside the purification cabinet. The tail gas emission structure for a heating boiler provided by this utility model has the technical effects of cooling high-temperature tail gas, adsorbing large particulate matter, and reducing damage to purification materials.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The exhaust gas emission structure disclosed in this utility model is mainly used in scenarios where exhaust gas needs to be cooled during exhaust gas purification to facilitate the replacement of purification materials.

[0019] Reference Figure 1 , Figure 2 and Figure 3A tail gas emission structure for a heating boiler includes a base 1 and a water tank 2 fixed on its top left side. A connecting pipe 3 is fixedly connected to the top of the water tank 2, and a purification cabinet 4 is fixedly connected to the other end of the connecting pipe 3. An exhaust port 5 is fixedly connected to the top of the purification cabinet 4. The structure also includes: a cooling mechanism: the cooling mechanism includes an air intake hood 6, which is fixedly connected to the left side of the water tank 2. A fan blade 7 is provided inside the air intake hood 6. A transmission pipe 8 is fixedly connected to the top of the air intake hood 6. A gear 9 is fixedly connected to the bottom right end of the fan blade 7. A rotating shaft 10 is fixedly connected to the right side of the gear 9. A stirring plate 11 is fixedly connected to the surface of the rotating shaft 10. Connection ports 12 are provided on the front and rear sides of the stirring plate 11; and a purification mechanism: the purification mechanism is slidably connected inside the purification cabinet 4.

[0020] Specifically, when the high-temperature and high-pressure exhaust gas is discharged into the intake hood 6, the airflow will drive the fan blades 7 to rotate, which in turn will drive the stirring plate 11 to stir the water through the transmission of gear 9 and rotating shaft 10. At the same time, the exhaust gas entering the intake hood 6 will enter the water tank 2 along the transmission pipe 8 and then be discharged into the water in the water tank 2. The stirring plate 11 can increase the fluidity of the water and break up the large air bubbles in the water, thereby absorbing the temperature in the exhaust gas and adsorbing large particulate matter. The cooled exhaust gas is discharged into the purification cabinet 4 along the connecting pipe 3 for further purification and absorption.

[0021] The fan blade 7 is rotatably connected to the inside of the air intake shroud 6 via a rotating rod. There are two gears 9, one of which is fixedly connected to the right end of the fan blade 7 and the other is fixedly connected to the left end of the rotating shaft 10. The two gears 9 mesh with each other. Through the design of the fan blade 7 and gears 9, the exhaust gas is further utilized. The power generated by the flow of exhaust gas is used to stir the water and improve the cooling effect.

[0022] The other end of the transmission pipe 8 is located at the bottom of the water tank 2. The connection port 12 is fixedly connected to the front and rear sides of the water tank 2. A filter screen is installed inside the connection port 12. By installing a filter screen in the connection port 12, the particles adsorbed in the water can be filtered to prevent harmful substances from being discharged to the outside world and to facilitate centralized treatment later.

[0023] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the purification mechanism includes a purification box 13, which is slidably connected inside the purification cabinet 4. A handle 14 is fixedly connected to the front side of the purification box 13. A slide groove 15 is provided inside the purification box 13. A placement plate 16 slides inside the slide groove 15. A fixing plate 17 is rotatably connected to the top of the placement plate 16.

[0024] Specifically, as the exhaust gas diffuses upward from the bottom of the purification cabinet 4, it comes into contact with the layers of filter purification materials set inside the placement plate 16, absorbing the harmful substances contained therein, thereby meeting the emission standards and being discharged from the exhaust port 5. After long-term purification, the design of the purification box 13 and the placement plate 16 being removable facilitates the replacement of the purification materials, ensuring the purification effect of the device.

[0025] The placement plates 16 are four in number and are equidistantly slidably connected in the slide groove 15. Each placement plate 16 has a cavity for placing purification materials. The right end of the fixing plate 17 has a buckle corresponding to the placement plate 16. The surfaces of the placement plates 16 and the fixing plate 17 are provided with strip-shaped ventilation holes. The multi-stage placement plates 16 can place corresponding purification and adsorption materials according to the composition of harmful substances in the exhaust gas, thereby improving the purification effect.

[0026] Reference Figure 1 and Figure 4 In a preferred embodiment, the right end of the connecting pipe 3 is connected to the bottom of the purification cabinet 4, and the bottom of the purification cabinet 4 is fixedly connected to the top right side of the base 1.

[0027] Specifically, after the exhaust gas enters from the bottom of the purification cabinet 4, the subsequent entry of exhaust gas can generate pressure, which helps the exhaust gas to pass through the purification layer better.

[0028] Working principle: During use, when treating exhaust gas, connect the inlet pipe to the front connection port 12 and the drain pipe to the rear connection port 12 to supply tap water to the water tank 2. After placing the purification material corresponding to the harmful substances to be filtered in the placement plate 16, connect the air intake hood 6 to the exhaust end of the heating boiler. When the high-temperature and high-pressure exhaust gas is discharged into the air intake hood 6, the airflow will drive the fan blade 7 to rotate, which will drive the gear 9 on the right end of the fan blade 7 to rotate, and then drive the other gear 9 meshing at the bottom to rotate. Under the transmission of the rotating shaft 10, the stirring plate 11 will be driven to stir in the water. The water flow entering from the front connection port 12 will also provide some power for the stirring plate 11. At the same time, the exhaust gas entering the air intake hood 6 will enter the water tank 2 along the transmission pipe 8, and then be discharged. The rotating stirring plate 11 in the water tank 2 increases the water's fluidity and breaks up large air bubbles, thus absorbing heat from the exhaust gas and adsorbing large particles. The cooled exhaust gas is discharged into the purification cabinet 4 along the connecting pipe 3. As the exhaust gas diffuses upward from the bottom of the purification cabinet 4, it comes into contact with the layers of filter materials inside the placement plate 16, absorbing and filtering the harmful substances it contains, thereby meeting emission standards and being discharged from the exhaust port 5. After long-term purification, the purification box 13 can be pulled forward by the handle 14, and the placement plate 16 can be pulled out to the right. The fixing plate 17 can be opened to replace the purification materials. After replacement, the placement plate 16 and purification box 13 can be put back in sequence to continue exhaust gas purification.

[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
