Description

Technical Field

[0001] This application belongs to the field of combustion engine technology, specifically a cooling device for a built-in biomass combustion engine. Background Technology

[0002] With the increasing severity of the global energy crisis and environmental pollution, biomass energy, as a renewable and low-carbon energy form, has received widespread attention. Built-in biomass burners, through optimized combustion chamber structure, improved feeding system, and air distribution design, achieve complete combustion of biomass fuel, improve thermal efficiency, and reduce pollutant emissions.

[0003] For example, application CN221259101U discloses a dust-free built-in biomass burner, whose structure includes a body, a conveying auger, a furnace, a hopper, a blower, and a centrifugal dust collection chamber. A waste heat recovery box is installed above the furnace. The waste heat recovery box is equipped with a temperature sensor, a first solenoid valve, a second solenoid valve, a liquid level sensor I, and a liquid level sensor II. The temperature sensor is fixedly connected to one end of the waste heat recovery box, the first solenoid valve is sealed to one side of the upper end of the waste heat recovery box, and the second solenoid valve is sealed to the lower part of the other end of the waste heat recovery box. This utility model realizes the recovery of heat generated during the use of the burner, avoids the direct emission of heat energy generated during biomass combustion, reduces the waste of heat energy generated during biomass combustion, and improves the energy-saving and environmental protection concept of the burner during use.

[0004] However, the heat generated by combustion in this application can cause the combustion furnace to deform, and the combustibles do not have secondary combustion support, resulting in incomplete combustion, low energy collection and utilization efficiency, and short equipment lifespan. Utility Model Content

[0005] The purpose of this application is to provide a cooling device for a built-in biomass burner in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A cooling device for a built-in biomass burner includes a main equipment shell, an ash collection box fixedly connected to the bottom of the equipment shell, an ash drain pipe fixedly connected to the top of the ash collection box, a combustion furnace fixedly connected to the top of the ash drain pipe, a flame nozzle fixedly connected to the top of the combustion furnace, uniformly distributed jet pipes fixedly connected around the flame nozzle, a cooling water layer shell fixedly connected to the outer end of the jet pipes, a conveying auger water-cooled shell fixedly connected to the outer side of the cooling water layer shell, and a cooling air layer shell fixedly connected to the outer side of the conveying auger water-cooled shell.

[0007] By adopting the above technical solution, during the operation of the equipment, the water pump starts and delivers water cooled by the cooling tank through the inlet pipe to the space between the combustion furnace and the cooling water layer shell. The water fills the space between the combustion furnace, the cooling water layer shell, and the water-cooled inner shell of the conveying auger, reducing the heat on the combustion furnace and the water-cooled inner shell of the conveying auger. When the water is full, the solenoid valve opens, and the water carries away the heat through the outlet pipe into the cooling tank, where it is then circulated again, allowing the equipment to continue cooling. The air pump can be activated, generating gas that enters the space between the cooling water layer shell and the cooling air layer shell through the air delivery pipe. This carries away some of the heat lost from the water, and the gas is then ejected through the jet pipe into the burner nozzle, efficiently collecting heat and preventing energy waste. Simultaneously, the gas ejected into the burner nozzle provides secondary combustion support, improving combustion efficiency. The operation of this high-efficiency device fully collects combustion energy, improving energy utilization efficiency, and protects the equipment from deformation due to excessive heat, thus extending the equipment's service life.

[0008] In a preferred embodiment, an air pump is fixedly connected to the bottom upper part of the device housing, an air supply pipe is fixedly connected to the right side of the air pump, and a cooling air layer housing is fixedly connected to the other end of the air supply pipe.

[0009] By adopting the above technical solution, gas can be generated and enter between the outer shell of the cooling air layer and the outer shell of the cooling water layer to collect the heat lost by water cooling.

[0010] In a preferred embodiment, an outlet pipe is fixedly connected to the outer side of the cooling water layer shell, a cooling tank is fixedly connected to the outer side of the outlet pipe, a water supply pipe is fixedly connected to the top of the cooling tank, a water pump is fixedly connected to the other end of the water supply pipe, an inlet pipe is fixedly connected to the left side of the water pump, and the other end of the inlet pipe is fixedly connected to the cooling water layer shell.

[0011] By adopting the above technical solution, cooling water can be circulated to ensure the continuous operation of the equipment.

[0012] In a preferred embodiment, a conveying auger water-cooled inner shell is fixedly connected to the inner side of the conveying auger water-cooled outer shell, and a combustion furnace is fixedly connected to the right side of the conveying auger water-cooled inner shell.

[0013] By adopting the above technical solution, water will be filled between the water-cooled outer shell and the water-cooled inner shell of the conveying auger, which can cool the heat generated by the collection equipment.

[0014] In a preferred embodiment, a feed hopper is fixedly connected to the outer side of the water-cooled inner shell of the conveying auger.

[0015] By adopting the above technical solution, it is convenient to place combustible materials.

[0016] In a preferred embodiment, a conveying auger is rotatably connected to the inner side of the water-cooled inner shell of the conveying auger.

[0017] By adopting the above technical solution, combustibles can be transported into the combustion furnace.

[0018] In a preferred embodiment, a solenoid valve is fixedly connected to the outside of the water outlet pipe.

[0019] By adopting the above technical solution, it can be ensured that the space between the cooling water layer shell and the combustion furnace is filled with water.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, during equipment operation, the water pump starts and delivers water cooled by the cooling tank through the inlet pipe to the space between the combustion furnace and the cooling water layer shell. The water fills the space between the combustion furnace, the cooling water layer shell, and the water-cooled inner shell of the conveying auger, reducing heat on these surfaces. When the space is full, the solenoid valve opens, and the water carries heat through the outlet pipe back into the cooling tank, where it circulates again, ensuring continuous cooling of the equipment. The air pump can be activated, generating gas that enters the space between the cooling water layer shell and the cooling air layer shell through the air delivery pipe. This gas carries away some of the heat lost from the water and is then ejected through the jet pipe into the burner nozzle, efficiently collecting heat and preventing energy waste. Simultaneously, the gas ejected into the burner nozzle provides secondary combustion support, improving combustion efficiency. The operation of this high-efficiency device fully collects combustion energy, improving energy utilization efficiency, and protects the equipment from deformation due to excessive heat, extending its service life.
