Description

Technical Field

[0001] This utility model relates to the field of air supply technology, specifically to an air supply device for biomass fuel power generation. Background Technology

[0002] Biomass energy refers to solar energy stored in biomass in the form of chemical energy. It is the fourth largest energy source after coal, oil, and natural gas. With increasing social attention to biomass energy, many countries and regions have encouraged or mandated its use through legislation because it plays an important role in addressing energy supply and demand imbalances, global climate change, and ecological environmental protection. It is also the most important new energy source.

[0003] In the field of biomass fuel power generation, the main role of air supply equipment in fuel power generation is to provide an appropriate amount of air to the combustion chamber or gasifier to support the full combustion or gasification of fuel. This helps to improve power generation efficiency, reduce fuel waste, and reduce emissions.

[0004] To improve resource utilization efficiency, existing air supply systems typically recycle and transport exhaust gas from the power generation system to the combustion chamber. However, this exhaust gas contains numerous particulate impurities, which can affect the combustion efficiency of biomass fuel. Therefore, filtration mechanisms are often installed within the air supply equipment. However, traditional filtration mechanisms are prone to clogging after filtering the exhaust gas, requiring frequent cleaning. Furthermore, the traditional filter plates are located inside the air supply equipment, making cleaning difficult and time-consuming, thus reducing the efficiency of the air supply equipment. Therefore, those skilled in the art have provided an air supply device for biomass fuel power generation to address the problems mentioned in the background. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an air supply device for biomass fuel power generation, which solves the problems of traditional filtration mechanisms being prone to clogging after filtering exhaust gas and requiring frequent cleaning, and the traditional filter plates being located inside the air supply device, making cleaning difficult and requiring a lot of time to disassemble, thus reducing the working efficiency of the air supply device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an air supply device for biomass fuel power generation, comprising a blower, a return air duct, and an air supply pipe. One side of the blower is connected to the return air duct, and the other side of the blower is connected to the air supply pipe. A groove is formed in the upper side wall of the air supply pipe, and a through groove is formed on one side of the groove. A guide hood is installed on the upper side of the through groove, and a dust collection bag is connected to one side of the guide hood. A limit rod is installed on the upper side of the guide hood, and an insert plate is sleeved on the limit rod. A tension spring is connected to one end of the insert plate. A rotating shaft is rotatably engaged in the end of the through groove adjacent to the groove. A first baffle, a filter plate, and a second baffle are installed sequentially on the rotating shaft. The first baffle, the filter plate, and the second baffle are T-shaped. A slot is formed at the end of the second baffle away from the rotating shaft.

[0009] Preferably, the first baffle is fitted with the groove, and the exhaust gas is input into the air supply pipe by the blower. When the exhaust gas in the air supply pipe passes through the filter plate, it impacts the filter plate. At this time, the filter plate is in a vertical state under the engagement of the first baffle and the groove, thereby filtering the exhaust gas.

[0010] Preferably, a handle is installed on one side of the second baffle. By pulling the handle, the second baffle is flipped to a vertical position and in contact with the side wall of the shroud.

[0011] Preferably, the tension spring is sleeved with the limiting rod, one end of the tension spring is connected to the insert plate, and the other end is connected to the top side wall of the flow guide. The insert plate passes through the flow guide and is inserted into the slot, which has the effect of positioning the second baffle.

[0012] Preferably, the filter plate passes through the through groove. When the first baffle blocks the air supply pipe, the filter plate rotates into the through groove with the filter surface facing upward. After the exhaust gas impacts the first baffle, it is blocked and guided into the guide hood, thereby achieving the effect of backflushing and cleaning the filter plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a wind supply device for biomass fuel power generation, which has the following beneficial effects:

[0015] The air supply equipment in this utility model is designed to consist of a return air duct, a blower, and an air supply pipe. When filtering exhaust gas, the blower directs the exhaust gas into the air supply pipe. The exhaust gas in the air supply pipe is filtered by the filter plate. When the filter plate needs cleaning, the second baffle is pulled by the handle, causing it to flip vertically and fit against the side wall of the guide shroud. The insert plate on the guide shroud, under the limiting tension of the tension spring and the limiting rod, is inserted and positioned into the slot within the vertical section of the second baffle. Inside the air supply duct, the first baffle blocks the air supply duct, and the filter plate rotates into the through slot with the filter surface facing upwards. When the exhaust gas impacts the first baffle, it is blocked and guided into the guide hood, thus achieving the effect of backflushing and cleaning the filter plate. The cleaned particles are collected by the dust collection bag. After the filter plate is cleaned, the insert plate can be pulled out, allowing the first baffle, filter plate, and second baffle to return to their original positions to continue filtration. This air supply equipment does not require disassembly and cleaning of the filter plate, greatly improving the working efficiency of the air supply equipment. Attached Figure Description

A slot 1201 is formed at the end of the second baffle 12 away from the rotating shaft 9.

[0023] Please see Figure 2 , Figure 3 , Figure 4 The first baffle 10 is fitted with the groove 301. The exhaust gas is input into the air supply pipe 3 by the blower 1. When the exhaust gas in the air supply pipe 3 passes through the filter plate 11, it impacts the filter plate 11. At this time, the filter plate 11, under the engagement of the first baffle 10 and the groove 301, is in a vertical state, thereby filtering the exhaust gas. A handle 1202 is installed on one side of the second baffle 12. By pulling the second baffle 12 with the handle 1202, the second baffle 12 is flipped to a vertical state and fitted with the side wall of the guide shroud 4. The tension spring Spring 7 is sleeved with limiting rod 8. One end of tension spring 7 is connected to plate 6, and the other end is connected to the top side wall of guide shroud 4. Plate 6 penetrates guide shroud 4 and is inserted into slot 1201, which has the effect of positioning second baffle 12. Filter plate 11 penetrates through slot 302. When first baffle 10 blocks air supply pipe 3, filter plate 11 rotates into through slot 302, and the filter surface of filter plate 11 faces upward. After exhaust gas impacts first baffle 10, it is blocked and guided into guide shroud 4, thereby achieving the effect of backflushing and cleaning filter plate 11.

[0024] The air supply equipment in this utility model consists of a return air duct 2, a blower 1, and a blower 3. One side of the blower 1 is connected to the return air duct 2, which is used for the input of exhaust gas. The other side of the blower 1 is connected to the blower 3, which is used for the input of filtered exhaust gas.

[0025] A groove 301 is provided on the upper side wall of the air supply duct 3, and a through groove 302 is provided on one side of the groove 301. A guide hood 4 is provided above the through groove 302. A dust collection bag 5 is connected to one side of the guide hood 4.

A first baffle 10, a filter plate 11 and a second baffle 12 are arranged on the rotating shaft 9 at 90° intervals. The first baffle 10, the filter plate 11 and the second baffle 12 form a T-shape.

[0026] When filtering the exhaust gas, the blower 1 inputs the exhaust gas into the air supply pipe 3. When the exhaust gas in the air supply pipe 3 passes through the filter plate 11, it impacts the filter plate 11. At this time, the filter plate 11, under the engagement of the first baffle 10 and the groove 301, is in a vertical state, thereby filtering the exhaust gas. When the filter plate 11 needs to be cleaned, the second baffle 12 is pulled by the handle 1202, causing the second baffle 12 to flip to a vertical state and fit against the side wall of the guide shroud 4. At this time, the insert plate 6 on the guide shroud 4 is perpendicular to the second baffle 12 under the limiting tension of the tension spring 7 and the limiting rod 8. The upper end of the slot 1201 is inserted and positioned to position the second baffle 12. At this time, the first baffle 10 blocks the air supply pipe 3, and the filter plate 11 rotates into the through groove 302 with the filter surface of the filter plate 11 facing upward. After the exhaust gas impacts the first baffle 10, it is blocked and guided into the guide hood 4, thereby achieving the effect of back-blowing and cleaning the filter plate 11. The cleaned particles are collected by the dust collection bag 5. After the filter plate 11 is cleaned, the insert plate 6 can be pulled out so that the first baffle 10, the filter plate 11 and the second baffle 12 return to their original positions to continue filtration.
