Description

Technical Field

[0001] This utility model relates to the field of gas boiler technology, and more specifically, to a gas boiler with an auxiliary flue gas exhaust structure. Background Technology

[0002] Gas-fired boilers include gas-fired hot water boilers, gas-fired hot water boilers, and gas-fired steam boilers. Among them, gas-fired hot water boilers are also called gas-fired heating boilers and gas-fired bathing boilers. As the name suggests, gas-fired boilers refer to boilers that use gas as fuel. Compared with oil-fired boilers and electric boilers, gas-fired boilers are the most economical, so most people choose gas-fired boilers for steam, heating, and bathing. During operation, the flue gas produced by gas-fired boilers needs to be discharged to external flue gas treatment equipment through exhaust pipes. However, the existing technology has the following shortcomings in use: The exhaust pipe itself has a relatively simple structure. During the process of exhausting the smoke through the exhaust pipe, it is impossible to actively accelerate or guide the smoke, resulting in a slow exhaust speed. It is difficult to achieve efficient and rapid smoke exhaust and cannot meet actual needs.

[0003] Therefore, there is an urgent need for a gas-fired boiler with an auxiliary flue gas exhaust structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the problem that the existing exhaust pipes have a relatively simple structure, and cannot actively accelerate or guide the exhaust gas during the process of exhausting the smoke, resulting in a slow exhaust speed and difficulty in achieving efficient and rapid exhaust, thus failing to meet actual needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A gas-fired boiler with an auxiliary flue gas exhaust structure is proposed to improve the above-mentioned problems.

[0006] The application is as follows: A gas-fired boiler with an auxiliary flue gas exhaust structure includes a boiler body. A flue gas pipe is fixedly installed on the outside of the flue gas outlet of the boiler body. An outer ring is provided on the outer surface of the flue gas pipe. An air inlet is opened on the annular outer surface of the outer ring. An annular groove is opened on the annular inner surface of the outer ring. A plurality of parallelogram-shaped ventilation openings are arranged linearly around the flue gas pipe. An open mounting base is fixedly connected to the outer surface of the outer ring. A fan is fixedly installed on one side of the mounting base. A filter mechanism is provided at the end of the flue gas pipe away from the boiler body.

[0007] As a preferred technical solution of this application, the filtration mechanism includes a connecting ring fixedly installed on the outer side of the end of the flue pipe away from the boiler body, and a porous ceramic filter is installed on the inner surface of the connecting ring.

[0008] As a preferred technical solution of this application, the air inlet is connected to the annular slot, and the annular slot is connected to the parallelogram ventilation opening.

[0009] As a preferred technical solution of this application, the exhaust pipe is an L-shaped bend, and the openings at both ends of the exhaust pipe are consistent.

[0010] As a preferred technical solution of this application, the outer ring is fixedly welded to the outer surface of the exhaust pipe.

[0011] As a preferred technical solution of this application, the mounting base is located outside the air inlet.

[0012] As a preferred technical solution of this application, the connecting ring is provided with a plurality of mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By using an outer ring, air inlet, annular slot, parallelogram vent, mounting base and fan, the flue gas can be guided and diverted, increasing the flow rate of the flue gas in the exhaust pipe, so that the flue gas can be discharged from the exhaust pipe more quickly, improving the exhaust efficiency and meeting actual needs.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Example

[0022] like Figure 1-4 As shown, the gas-fired boiler with an auxiliary flue gas structure proposed in this embodiment includes a boiler body 1. A flue gas pipe 2 is fixedly installed on the outside of the flue gas outlet of the boiler body 1. The flue gas pipe 2 is an L-shaped bend, and the openings at both ends of the flue gas pipe 2 are consistent. An outer ring 3 is provided on the outer surface of the flue gas pipe 2. An air inlet 4 is opened on the annular outer surface of the outer ring 3. An annular groove 5 is opened on the annular inner surface of the outer ring 3. Several parallelogram-shaped ventilation openings 6 are arranged linearly around the flue gas pipe 2. The air inlet 4 is connected to the annular groove 5, and the annular groove 5 is connected to the parallelogram-shaped ventilation openings 6. An open mounting base 7 is fixedly connected to the outer surface of the outer ring 3. A fan 8 is fixedly installed on one side of the mounting base 7. A filter mechanism is provided at the end of the flue gas pipe 2 away from the boiler body 1. The blower 8 is electrically connected to an external control power supply. When the boiler body 1 is running, the generated flue gas is discharged into the flue pipe 2. The blower 8 is started, and airflow is injected into the annular slot 5 through the air inlet 4. The airflow enters several parallelogram vents 6 through the annular slot 5. The airflow is guided obliquely upward through the multiple parallelogram vents 6 into the flue pipe 2, so that the airflow and flue gas are mixed, making the flue gas flow more orderly and avoiding turbulence, eddies and other flow states that are not conducive to flue gas discharge. This increases the gas velocity inside the flue pipe 2, so that the flue gas can be discharged from the flue pipe 2 more quickly, improving the flue gas discharge efficiency. At the same time, the orderly and rapid flue gas flow can reduce the probability of particulate matter in the flue gas adhering to the inner wall of the flue pipe 2, reduce ash accumulation, help extend the service life of the flue pipe 2, and reduce subsequent maintenance costs.

[0023] like Figure 1 and Figure 3As shown, the filtration mechanism includes a connecting ring 9 fixedly installed on the outer side of the end of the flue pipe 2 away from the boiler body 1, and a porous ceramic filter 10 is installed on the inner surface of the connecting ring 9. The porous ceramic filter 10 has a uniform pore structure and high mechanical strength, and can withstand high temperature and chemical corrosion. When flue gas passes through the porous ceramic filter 10, particulate impurities will be trapped in the pores, achieving preliminary filtration of the flue gas. It can effectively remove tiny particles in the flue gas and improve the quality of the filtered flue gas.

[0024] like Figure 2 As shown, the outer ring 3 is fixedly welded to the outer surface of the exhaust pipe 2 to ensure the stability of the outer ring 3 installation.

[0025] like Figure 2 As shown, the mounting base 7 is located outside the air inlet 4. When the fan 8 is running, the external airflow enters the annular slot 5 through the mounting base 7 and the air inlet 4.

[0026] like Figure 3 As shown, the connecting ring 9 has several mounting holes 11. These mounting holes 11 facilitate the subsequent connection of the connecting ring 9 to the external flue gas treatment equipment via bolts, thus facilitating the subsequent treatment of the flue gas discharged from the exhaust pipe 2.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
