Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a biomass gasification boiler with waste heat recovery. Background Technology

[0002] A biomass gasification boiler is a boiler that uses biomass energy as fuel. The combustion of biomass energy in the boiler generates excess heat, which is released with the combustion gases. This heat can be collected and utilized in a reasonable manner.

[0003] Existing technology, patent CN219798085U, discloses a biomass boiler with waste heat recovery capability, including a device shell and a cleaning structure. A heat exchanger, composed of multiple heat exchange plates, is installed at the upper end of the device shell. The cleaning structure is located inside the upper part of the device shell and includes a first drive motor. A reciprocating screw is installed at the output end of the first drive motor. A strip-shaped shell is threaded onto the outside of the reciprocating screw and slidably connected to the device shell via a sliding rod. Several nozzles are installed on the left and right sides of the outer side of the strip-shaped shell, and automatic brush structures are provided on the left and right sides of the lower end of the strip-shaped shell. This utility model, by adding a cleaning structure inside the biomass boiler, makes cleaning the exterior of the waste heat recovery structure more convenient.

[0004] This device recovers heat from the gas by using a combination of a heat exchanger and a water storage tank. However, while the device cleans the heat exchanger by driving a roller brush via a drive mechanism, which is effective, the roller brush and drive mechanism themselves become contaminated. Furthermore, cleaning dead zones are left in the corners of the heat exchanger. Moreover, the recovered gas is not purified, and direct emission causes environmental pollution. Therefore, a biomass gasification boiler with waste heat recovery is needed. Utility Model Content

[0005] The purpose of this invention is to provide a biomass gasification boiler with waste heat recovery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass gasification boiler with waste heat recovery, comprising a biomass gasification boiler body, a heat exchanger installed on the top of the biomass gasification boiler body, a water tank installed on the heat exchanger, support columns installed on the biomass gasification boiler body and the heat exchanger, an air outlet provided on the top of the biomass gasification boiler body, a first disassembly pipe detachably installed inside the air outlet, a first flexible hose installed on the first disassembly pipe, a filter cartridge installed on the first flexible hose, a purification cartridge connected in series on the filter cartridge, a second flexible hose installed at the air outlet end of the purification cartridge, an air inlet pipe installed at the air inlet of the heat exchanger, a second disassembly pipe detachably installed inside the air inlet pipe, and a second flexible hose installed on the second disassembly pipe.

[0007] Preferably, a miniature mounting sleeve is installed on the outer wall of both the air outlet and the air inlet pipe, and an L-shaped plug is installed on both the first and second disassembly pipes. A locking block is movably installed inside the miniature mounting sleeve, and the locking block is engaged with the L-shaped plug.

[0008] Preferably, a spring and a guide telescopic rod are installed inside the miniature mounting sleeve, and the other end of the spring and the guide telescopic rod are mounted on the locking block.

[0009] Preferably, the miniature mounting sleeve has a slot, the card block has a lever installed on it, and the lever is slidably installed in the slot.

[0010] Preferably, both the first and second disassembly pipes are equipped with positioning rods, and the air outlet and the outer wall of the air inlet pipe are equipped with positioning sleeves, with the positioning rods inserted into the positioning sleeves.

[0011] Preferably, the heat exchanger is equipped with a return pipe at the exhaust end, an exhaust pipe is installed on the return pipe, and a first valve body and a second valve body are respectively installed on the exhaust pipe and the return pipe.

[0012] Preferably, the water tank is equipped with a water outlet pipe, and the water outlet pipe is equipped with a No. 3 valve body.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the gas generated within the biomass gasification boiler is discharged through an outlet. The discharged gas then flows through a first disassembly pipe into a first flexible hose, and from there into a filter cartridge for filtration. This filtration removes impurities from the gas, preventing contamination of the heat exchanger. The filtered gas then enters a purification cartridge for further purification, removing harmful substances and preventing direct emissions that could cause environmental pollution.

[0015] This invention features a sliding mechanism where a sliding block within a slot allows a locking block to enter a miniature mounting sleeve. This eliminates the locking block's engagement with the L-shaped insert, enabling the first and second disassembly tubes to be directly pulled out from the air outlet and inlet pipes, facilitating the assembly and disassembly of the filter and purification cartridges. The first and second disassembly tubes are then inserted into the air outlet and inlet pipes respectively; the spring action causes the locking block to engage within the L-shaped insert, allowing for quick and easy replacement of the filter and purification cartridges while ensuring effective gas filtration and purification.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0022] like Figure 1-4As shown, this embodiment provides a biomass gasification boiler with waste heat recovery, including a biomass gasification boiler body 1, a heat exchanger 2 installed on the top of the biomass gasification boiler body 1, a water tank 3 installed on the heat exchanger 2, support columns 4 installed on the biomass gasification boiler body 1 and the heat exchanger 2, a gas outlet 5 provided on the top of the biomass gasification boiler body 1, a first disassembly pipe 6 detachably installed in the gas outlet 5, a first flexible hose 7 installed on the first disassembly pipe 6, a filter cartridge 8 installed on the first flexible hose 7, and a purification cartridge connected in series on the filter cartridge 8. 9. A second flexible hose 10 is installed at the outlet of the purification cylinder 9, and an inlet pipe 11 is installed at the inlet of the heat exchanger 2. A second disassembly pipe 12 is detachably installed inside the inlet pipe 11, and the second flexible hose 10 is installed on the second disassembly pipe 12. The gas generated in the biomass gasification boiler body 1 is discharged through the outlet 5. The gas discharged through the outlet 5 enters the first flexible hose 7 through the first disassembly pipe 6, and then enters the filter cylinder 8 for filtration to remove impurities mixed in the gas and prevent pollution of the heat exchanger 2. The gas filtered by the filter cylinder 8 enters the purification cylinder 9 for purification to remove harmful substances and prevent direct discharge that would cause environmental pollution. The gas treated by the filter cylinder 8 and the purification cylinder 9 enters the heat exchanger 2 sequentially through the second flexible hose 10, the second disassembly pipe 12, and the inlet pipe 11, and the heat exchanger 2 recovers heat. The recovered heat heats the water stored in the water tank 3, which can play a role in heat recovery and utilization.

[0023] To facilitate the disassembly and replacement of filter cartridge 8 and purification cartridge 9, and to ensure the filtration and purification effect on the gas. Miniature mounting sleeves 13 are installed on the outer walls of both the air outlet 5 and the air inlet pipe 11. L-shaped inserts 14 are installed on both the first disassembly pipe 6 and the second disassembly pipe 12. A locking block 15 is movably installed inside the miniature mounting sleeve 13 and engages with the L-shaped insert 14. A spring 16 and a guide telescopic rod 17 are installed inside the miniature mounting sleeve 13, and the other ends of the spring 16 and the guide telescopic rod 17 are installed on the locking block 15. A groove 18 is provided on the miniature mounting sleeve 13, and a lever 19 is installed on the locking block 15. The lever 19 is slidably installed in the groove 18. After long-term use, the lever 19 can be moved. The lever 19 slides in the groove 18 and can drive the locking block 15 into the miniature mounting sleeve 13, so that the locking block 15 is no longer engaged with the L-shaped insert 14. At this time, the first disassembly pipe 6 and the second disassembly pipe 12 can be directly pulled out from the air outlet 5 and the air inlet pipe 11, making it convenient to disassemble and reassemble the filter cartridge 8 and the purification cartridge 9.

[0024] Next, insert the No. 1 disassembly tube 6 and the No. 2 disassembly tube 12 into the air outlet 5 and the air inlet tube 11 respectively. The locking block 15 will be squeezed into the miniature mounting sleeve 13 by the L-shaped plug 14. At this time, the spring 16 and the guide telescopic rod 17 will also be compressed. When the locking block 15 and the locking hole on the L-shaped plug 14 coincide, the locking block 15 will be driven into the L-shaped plug 14 under the action of the spring 16. The filter cartridge 8 and the purification cartridge 9 can be replaced quickly. The operation is convenient and ensures the filtration and purification effect of the gas.

[0025] To position the L-shaped insert 14, positioning rods 20 are installed on both the first disassembly pipe 6 and the second disassembly pipe 12, and positioning sleeves 21 are installed on the outer walls of the air outlet 5 and the air inlet pipe 11. The positioning rods 20 are inserted into the positioning sleeves 21. The positioning rods 20 are pre-aligned with the positioning sleeves 21 and inserted. At this time, the L-shaped insert 14 will correspond to the locking block 15, which can position the L-shaped insert 14.

[0026] To improve gas treatment efficiency and heat exchange efficiency through multiple filtrations, purifications, and heat exchanges, a return gas pipe 22 is installed at the exhaust end of the heat exchanger 2. An exhaust pipe 23 is installed on the return gas pipe 22, and a first valve body 24 and a second valve body 25 are respectively installed on the exhaust pipe 23 and the return gas pipe 22. When the second valve body 25 is opened and the first valve body 24 is closed, the heat-exchanged gas re-enters the biomass gasification boiler body 1 through the return gas pipe 22 and exits through the gas outlet 5. This allows for repeated filtration, purification, and heat exchange of the gas, resulting in good gas treatment and high heat recovery efficiency.

[0027] In order to drain the water in water tank 3 for reuse, water tank 3 is equipped with a water outlet pipe 26, and a third valve body 27 is installed on the water outlet pipe 26; the third valve body 27 is opened, and the heated water is collected and reused through the water outlet pipe 26.

[0028] Working Principle: During operation, the gas generated within the biomass gasification boiler body 1 is discharged through outlet 5. The gas discharged through outlet 5 enters hose 7 via disassembly pipe 6, and then flows into filter cartridge 8 for filtration, removing impurities and preventing contamination of heat exchanger 2. The filtered gas then enters purification cartridge 9 for further purification, removing harmful substances and preventing direct emissions that could cause environmental pollution. It should be noted that filter cartridges 8 and 9 are existing components in the current technology; their specific structures and working principles are not detailed here. The gas treated by filter cartridges 8 and 9 then flows through hose 10, disassembly pipe 12, and inlet pipe 11 into heat exchanger 2, where heat is recovered. This recovered heat heats the water stored in water tank 3, thus achieving heat recovery and utilization. Valve 27 is opened, and the heated water is collected and utilized through outlet pipe 26. Open valve body 25 and close valve body 24. The gas that has undergone heat exchange will re-enter the biomass gasification boiler body 1 through return gas pipe 22 and be discharged from the biomass gasification boiler body 1 through gas outlet 5. The gas can be repeatedly filtered, purified and heat exchanged, resulting in good gas treatment effect and high heat recovery efficiency. After prolonged use, the lever 19 can be moved. The lever 19 slides in the lever groove 18, which can drive the locking block 15 into the miniature mounting sleeve 13, so that the locking block 15 is no longer locked with the L-shaped plug 14. At this time, the first disassembly tube 6 and the second disassembly tube 12 can be directly pulled out from the air outlet 5 and the air inlet pipe 11, making it convenient to disassemble and reassemble the filter cartridge 8 and the purification cartridge 9. Then, the first disassembly tube 6 and the second disassembly tube 12 are inserted into the air outlet 5 and the air inlet pipe 11 respectively. The locking block 15 will be squeezed into the miniature mounting sleeve 13 by the L-shaped plug 14. At this time, the spring 16 and the guide telescopic rod 17 will also be compressed. When the locking block 15 and the locking hole on the L-shaped plug 14 coincide, the spring 16 will drive the locking block 15 to lock into the L-shaped plug 14, which can quickly complete the replacement of the filter cartridge 8 and the purification cartridge 9. The operation is convenient and ensures the filtration and purification effect of the gas.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
