Description

Technical Field

[0001] This utility model relates to the field of heating boiler technology, specifically to a tail gas treatment device for heating boilers. Background Technology

[0002] The primary function of a heating boiler is to provide heat to the spaces within a building, maintaining a comfortable indoor temperature. In cold seasons, it distributes heat into the indoor air by delivering hot water or steam to various heating devices (such as radiators, underfloor heating pipes, and fan heaters). For example, in northern residential buildings, hot water from a boiler circulates in pipes. As the hot water flows past radiators, the metal fins transfer heat to the surrounding air. The heated air rises, creating natural convection, which gradually warms the entire room. In large commercial buildings or industrial plants, high-temperature steam from a steam boiler can be delivered to radiators via steam pipes. Because steam has a higher calorific value, it can meet the heating needs of large areas and high spaces. Many heating boilers also provide domestic hot water. In some homes or hotels, boilers can heat water to a suitable temperature to meet people's daily hot water needs, such as for bathing and washing dishes. By installing equipment such as hot water exchangers, the hot water produced by the boiler can exchange heat with domestic water, thereby heating the domestic water. This method is both convenient and efficient. Especially in places with centralized heating systems, using heating boilers to provide domestic hot water can reduce the investment in additional hot water equipment.

[0003] The existing technical solutions have the following drawbacks: When treating the exhaust gas generated by heating boilers, the adsorption operation is often carried out by filter plates. However, the particles contained in the exhaust gas will gradually accumulate on the surface of the filter plates during long-term operation, which will cause blockage. Once the filter plates are blocked, the exhaust gas cannot pass through smoothly, which greatly reduces the filtration effect of the exhaust gas and ultimately leads to a significant reduction in the overall exhaust gas treatment efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a tail gas treatment device for heating boilers, which has the advantage of easy filtration. It solves the problem that when treating tail gas generated by heating boilers, adsorption is often performed using filter plates. However, the particles contained in the tail gas gradually accumulate on the surface of the filter plates during long-term operation, causing blockage. Once the filter plates are blocked, the tail gas cannot pass through smoothly, resulting in a significant reduction in the filtration effect and ultimately a significant decrease in the overall tail gas treatment efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tail gas treatment device for a heating boiler, comprising a base plate, with support legs fixedly connected to the four corners of the bottom of the base plate, a sedimentation tank fixedly connected to the top of the base plate, a shell provided on the top of the sedimentation tank, the bottom of the shell being fixedly connected to the top of the base plate, a connecting pipe connected to the left side of the shell, the input end of the connecting pipe being connected to the tail gas output end of an external heating boiler, a discharge pipe connected to the right side of the shell, a filter plate fixedly connected to the left side of the discharge pipe, two discharge pipes, a cooling mechanism provided on the top of the base plate, and a cleaning mechanism provided on the top of the base plate.

[0006] As a preferred embodiment of this utility model, the cooling mechanism includes a mounting frame, the bottom of which is fixedly connected to the top of the sedimentation tank, and a water pump is fixedly connected to the top of the mounting frame. The input end of the water pump is connected to a pumping pipe, the output end of the water pump is connected to a delivery pipe, and the output end of the delivery pipe is connected to a spray plate. Both ends of the spray plate are fixedly connected to the inner wall of the housing.

[0007] In a preferred embodiment of this utility model, the cleaning mechanism includes a reinforcing frame, the right side of which is fixedly connected to the right side of the inner wall of the housing. A waterproof motor is fixedly connected inside the reinforcing frame, and a drive wheel is fixedly connected to the output end of the waterproof motor. There are two drive wheels, and a drive shaft is provided at the bottom of the waterproof motor. There are two drive shafts, and a driven wheel is fixedly connected to one end of each drive shaft. The drive wheel and the driven wheel are rotatably connected by a belt, and a cleaning brush is fixedly connected to the other end of the drive shaft.

[0008] As a preferred embodiment of this invention, the number of cleaning brushes is several, and the several cleaning brushes are arranged in a ring.

[0009] As a preferred embodiment of this invention, a filter box is fixedly connected inside the sedimentation tank, and the filter box is located at the bottom of the pumping pipe.

[0010] As a preferred embodiment of this invention, an observation window is provided on the front side of the housing, and the observation window is located at the top of the bottom plate.

[0011] As a preferred embodiment of this utility model, a limiting plate is fixedly connected to the rear side of the housing, and the interior of the limiting plate is snapped into the surface of the conveying pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a cooling mechanism to cause large particles in the exhaust gas to fall into the sedimentation tank under the influence of gravity and water mist. The cleaning mechanism effectively prevents excessive impurities from adhering to the filter plate surface, ensuring that the filter plate does not become clogged. This solves the problem that in treating exhaust gas from heating boilers, where filter plates are often used for adsorption, particles in the exhaust gas gradually accumulate on the filter plate surface over time, causing blockage. Once the filter plate is clogged, the exhaust gas cannot pass smoothly, significantly reducing the filtration effect and ultimately leading to a substantial decrease in the overall exhaust gas treatment efficiency. This invention offers the advantage of easy filtration.

[0014] 2. This utility model, by setting up a cooling mechanism, first starts a water pump when treating the exhaust gas of a heating boiler. The input end of the water pump draws water from inside the sedimentation tank through a water suction pipe. Then, the output end of the water pump delivers the water to a delivery pipe, which further delivers the water to a spray plate. At this time, the exhaust gas transmitted by the connecting pipe meets the water mist sprayed from the spray plate. Under the action of the water mist, large particles in the exhaust gas fall into the sedimentation tank due to gravity, thereby achieving the initial cooling of the exhaust gas and the separation of large particles.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a tail gas treatment device for a heating boiler, including a base plate 1, with support legs 2 fixedly connected to the four corners of the bottom of the base plate 1, a sedimentation tank 3 fixedly connected to the top of the base plate 1, a shell 4 set on the top of the sedimentation tank 3, the bottom of the shell 4 fixedly connected to the top of the base plate 1, a connecting pipe 5 connected to the left side of the shell 4, the input end of the connecting pipe 5 connected to the tail gas output end of an external heating boiler, a discharge pipe 6 connected to the right side of the shell 4, a filter plate 7 fixedly connected to the left side of the discharge pipe 6, and two discharge pipes 6, a cooling mechanism 8 set on the top of the base plate 1, and a cleaning mechanism 9 set on the top of the base plate 1.

[0022] refer to Figure 3 The cooling mechanism 8 includes a mounting frame 81, the bottom of which is fixedly connected to the top of the sedimentation tank 3. A water pump 82 is fixedly connected to the top of the mounting frame 81. The input end of the water pump 82 is connected to a pumping pipe 83, and the output end of the water pump 82 is connected to a delivery pipe 84. The output end of the delivery pipe 84 is connected to a spray plate 85, and both ends of the spray plate 85 are fixedly connected to the inner wall of the housing 4.

[0023] As a technical optimization of this utility model, by setting a cooling mechanism 8, when treating the exhaust gas of the heating boiler, the water pump 82 is first started. The input end of the water pump 82 draws water from the inside of the sedimentation tank 3 through the water pumping pipe 83. Then the output end of the water pump 82 delivers the water to the delivery pipe 84. The delivery pipe 84 further delivers the water to the spray plate 85. At this time, the exhaust gas transmitted by the connecting pipe 5 meets the water mist sprayed by the spray plate 85. Under the action of the water mist, the large particles in the exhaust gas fall into the inside of the sedimentation tank 3 due to gravity, thereby achieving the initial cooling of the exhaust gas and the separation of large particles.

[0024] refer to Figure 4 The cleaning mechanism 9 includes a reinforcing frame 91, the right side of which is fixedly connected to the right side of the inner wall of the housing 4. A waterproof motor 92 is fixedly connected inside the reinforcing frame 91. A drive wheel 93 is fixedly connected to the output end of the waterproof motor 92. There are two drive wheels 93. A drive shaft 94 is provided at the bottom of the waterproof motor 92. There are two drive shafts 94. A driven wheel 95 is fixedly connected to one end of the drive shaft 94. The drive wheel 93 and the driven wheel 95 are rotatably connected by a belt. A cleaning brush plate 96 is fixedly connected to the other end of the drive shaft 94.

[0025] As a technical optimization of this utility model, by setting up a cleaning mechanism 9, the output end of the waterproof motor 92 drives the drive wheel 93 to rotate, and the drive wheel 93 drives the driven wheel 95 to rotate synchronously via a belt. The driven wheel 95 drives the drive shaft 94 connected to it to rotate, and finally the drive shaft 94 drives the cleaning brush plate 96 to brush the surface of the filter plate 7. In this way, it is possible to effectively prevent excessive impurities from adhering to the surface of the filter plate 7, ensure that the filter plate 7 will not be blocked, and ensure the continuous and efficient operation of the exhaust gas treatment process.

[0026] refer to Figure 4 There are several cleaning brush plates 96, and these cleaning brush plates 96 are arranged in a ring.

[0027] As a technical optimization of this utility model, by setting the number of cleaning brush plates 96 to several, a more efficient and comprehensive brushing operation can be carried out on the surface of the filter plate 7, which greatly improves the cleaning efficiency and quality.

[0028] refer to Figure 3 A filter box 10 is fixedly connected inside the sedimentation tank 3, and the filter box 10 is located at the bottom of the water pumping pipe 83.

[0029] As a technical optimization of this utility model, by setting up a filter box 10, the water is effectively filtered by the filter box 10 when the water pumping pipe 83 performs the pumping operation, thereby preventing impurities in the water from being pumped into the water pump 82, ensuring the stable operation of the water pump 82 and the normal working order of the entire system, extending the service life of the equipment, and improving the reliability and safety of the system operation.

[0030] refer to Figure 1 An observation window 11 is provided on the front side of the housing 4, and the observation window 11 is located on the top of the base plate 1.

[0031] As a technical optimization of this utility model, by setting an observation window 11, the usage status of the filter plate 7 can be conveniently observed in real time through the window, so as to accurately determine whether it needs to be replaced and maintained, thereby effectively ensuring the continuous and stable operation of the exhaust gas treatment device, ensuring that it is always in a good working efficiency state, and greatly improving the reliability and safety of the entire heating boiler exhaust gas treatment system.

[0032] refer to Figure 2 A limiting plate 12 is fixedly connected to the rear side of the housing 4, and the interior of the limiting plate 12 is snapped into the surface of the conveying pipe 84.

[0033] As a technical optimization of this utility model, by setting the limiting plate 12, the conveying pipe 84 can be stably protected. During long-term operation, even if the water flow causes vibration, the conveying pipe 84 can be effectively prevented from loosening and gaps at the connection with the water pump 82 by the limitation and support of the limiting plate 12. This ensures the tightness and stability of the connection between the conveying pipe 84 and the water pump 82, maintains the normal, efficient and safe operation of the entire water conveying system, and provides a solid guarantee for the continuous operation of the heating boiler exhaust gas treatment.

[0034] The working principle and usage process of this utility model are as follows: When treating the exhaust gas of a heating boiler, the water pump 82 is started first. The input end of the water pump 82 draws water from the sedimentation tank 3 through the water pumping pipe 83. Then, the output end of the water pump 82 delivers the water to the delivery pipe 84, which further delivers the water to the spray plate 85. At this time, the exhaust gas transmitted by the connecting pipe 5 meets the water mist sprayed by the spray plate 85. Under the action of the water mist, large particles in the exhaust gas fall into the sedimentation tank 3 due to gravity, thereby achieving the initial cooling and separation of large particles from the exhaust gas. Next, the waterproof motor 92 is started. The output end of the waterproof motor 92 drives the drive wheel 93 to rotate. The drive wheel 93 drives the driven wheel 95 to rotate synchronously via a belt. The driven wheel 95 drives the drive shaft 94 connected to it to rotate. Finally, the drive shaft 94 drives the cleaning brush plate 96 to brush the surface of the filter plate 7. In this way, excessive impurities can be effectively prevented from adhering to the surface of the filter plate 7, ensuring that the filter plate 7 will not be blocked and ensuring the continuous and efficient operation of the exhaust gas treatment process.

[0035] In summary, the exhaust gas treatment device for this heating boiler, through the coordinated use of the base plate 1, support legs 2, sedimentation tank 3, shell 4, connecting pipe 5, discharge pipe 6, filter plate 7, cooling mechanism 8, and cleaning mechanism 9, solves the problem that when treating exhaust gas generated by heating boilers, the adsorption operation often relies on filter plates. However, the particles contained in the exhaust gas gradually accumulate on the surface of the filter plate during long-term operation, causing blockage. Once the filter plate is blocked, the exhaust gas cannot pass through smoothly, resulting in a significant reduction in the filtration effect and ultimately a significant decrease in the overall exhaust gas treatment efficiency.
