Description

Technical Field

[0001] The utility model relates to the field of temperature difference power generation, in particular to a temperature difference generator based on a swirl burner. Background Art

[0002] Thermoelectric generator is a commonly used power generation equipment. Patent publication CN107154752B discloses a thermoelectric generator. The combustion chamber of this thermoelectric generator is a square box. Since there is only one combustion chamber inside the box, the combustion chamber cannot cause the fuel burning inside to swirl. Therefore, the combustion chamber of this structure cannot fully burn the fuel, and the utilization efficiency of the heat generated by the fuel combustion is relatively low. Utility Model Content

[0003] In view of the above problems, the utility model proposes a temperature difference generator based on a swirl burner.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A temperature difference generator based on a swirl burner comprises a base, an inner tube, a first air inlet pipe and a second air inlet pipe, wherein a cavity is arranged in the base, the inner tube is arranged in the cavity, the first air inlet pipe and the second air inlet pipe are both arranged on the base, one pipe opening of the first air inlet pipe is located outside the base, and the other pipe opening of the first air inlet pipe is located in the inner tube, one pipe opening of the second air inlet pipe is located outside the base, and the other pipe opening of the second air inlet pipe is located between the inner wall of the base and the outer wall of the inner tube, a plurality of notches are arranged at the tube opening of the inner tube, and the distance between two adjacent notches is equal, an annular baffle is arranged in the base, and the annular baffle is located above the notch.

[0006] In this type of temperature difference generator, a cavity is provided inside the base, and an inner cylinder is provided in the cavity of the base. Gas (or other forms of fuel) enters the inner cylinder from the first air inlet pipe, and air enters between the outer wall of the inner cylinder and the inner wall of the base from the second air inlet pipe. The air and gas are mixed into a mixed airflow. The presence of the annular baffle forces the mixed airflow to flow out of the inner cylinder from between the notches, thereby forming a vortex, so that the fuel is fully burned. At the same time, due to the effect of the vortex, the hot air flows in one direction. It is only necessary to set a collector in this direction to fully utilize the heat, which effectively improves the utilization efficiency of the heat generated by the fuel.

[0007] To sum up, in this type of generator, an inner cylinder is set in the cavity of the base, the fuel gas enters the inner cylinder from the first air inlet pipe, and the air enters between the outer wall of the inner cylinder and the inner wall of the base from the second air inlet pipe. The air and the fuel gas are mixed to form a vortex, so that the fuel is fully burned, effectively improving the utilization efficiency of the heat generated by the fuel.

[0008] Specifically in this device, a connecting screw hole is opened on the step inside the base, and a connecting screw hole is opened on the ring baffle. During installation, the ring baffle is installed on the step of the base by screws, and the screws are located in the connecting screw holes.

[0009] Specifically, in order to make the gas and air mix more evenly and the gas burn more completely, in this temperature difference generator, the directions of the first air intake pipe and the second air intake pipe are set so that the directions of the first air intake pipe and the second air intake pipe are different, that is, the flow direction of the gas flowing out of the first air intake pipe is different from the flow direction of the gas flowing out of the second air intake pipe, and the two air flows merge to form a mixed vortex.

[0010] Specifically in this generator, in order to ensure the flow direction of the swirl after the two airflows are mixed, the notch at the mouth of the inner cylinder has the same rotation direction relative to the center axis of the cylinder, so that the hot air flow generated after combustion can flow to the top of the base.

[0011] Optionally, it also includes a heat exchange sleeve, a heat collector and a temperature difference power generation component, the heat exchange sleeve is arranged on the base, the space inside the heat exchange sleeve is connected to the cavity inside the base, the heat collector is arranged on the heat exchange sleeve, the temperature difference power generation component is arranged on the heat collector, and the temperature difference power generation component is located outside the heat exchange sleeve.

[0012] In this type of generator, the hot air flowing out of the base flows into the heat exchange sleeve. The function of the collector is to collect heat, and the function of the temperature difference power generation component is to generate electricity using the temperature difference. Specifically, in order to improve the power generation efficiency of the temperature difference power generation component, this generator is provided with a water cooling component on the temperature difference power generation component. The water cooling component and the collector are respectively located on both sides of the temperature difference power generation component. In this way, a relatively large temperature difference can be formed on both sides of the temperature difference power generation component, thereby improving the power generation efficiency of the temperature difference power generation component.

[0013] Specifically in this generator, two heat collectors are arranged on the heat exchange sleeve, and the two heat collectors are in a non-contact state, and a temperature difference generator is arranged on each heat collector.

[0014] Specifically in the generator, flanges are provided on the base and the heat exchange sleeve, and the flange on the base and the flange on the heat exchange sleeve are detachably connected together by bolts.

[0015] Optionally, the heat collector is provided with heat collecting pin fins, the heat collecting pin fins are located in the heat exchange sleeve, and the heat collecting pin fins are integrally formed with the heat collector.

[0016] Specifically, multiple collecting pin fins are set on each collector, and the collecting pin fins on the same collector are in a parallel and non-contact state. This design allows the hot air flowing through the collecting pin fins to fully exchange heat with the collecting pin fins, thereby improving the heat collection effect of the collecting pin fins, thereby increasing the temperature of the hot end of the thermoelectric power generation component.

[0017] Optionally, the heat collecting pin fins are circular, oval, square or hexagonal heat collecting pin fins.

[0018] Optionally, a temperature difference power generation component is arranged on the outer wall of the base.

[0019] The purpose of setting a thermoelectric power generation component on the outer wall of the base is to make full use of the heat on the base. At the same time, in order to ensure the power generation efficiency of the thermoelectric power generation component, a water cooling component is also provided on the thermoelectric power generation component on the base, and the power generation efficiency of the thermoelectric power generation component is higher.

[0020] Optionally, a bayonet is provided on the heat exchange sleeve, and the heat collector is fixed on the bayonet.

[0021] Specifically, the heat exchange sleeve is a square tube-shaped heat exchange sleeve, the bayonet is a square bayonet, the heat collector is a square block-shaped heat collector, and the square block-shaped heat collector is clamped and fixed in the square bayonet.

[0022] Optionally, the diameter of the first air intake pipe is smaller than the diameter of the second air intake pipe.

[0023] The diameter of the second air intake pipe is greater than the diameter of the first air intake pipe, which can ensure that the air intake amount is greater than the gas intake amount, thereby ensuring sufficient combustion of the gas.

[0024] The beneficial effect of the utility model is that an inner cylinder is arranged in the cavity of the base, the gas enters the inner cylinder from the first air inlet pipe, and the air enters between the outer wall of the inner cylinder and the inner wall of the base from the second air inlet pipe, the air and the gas are mixed to form a swirl, so that the fuel is fully burned, and the utilization efficiency of the heat generated by the fuel is effectively improved.

At the same time, due to the effect of the vortex, the hot air flows in one direction. It is only necessary to set the collector 2 in this direction to fully utilize the heat, which effectively improves the utilization efficiency of the heat generated by the fuel.

[0037] Specifically in this generator, in order to ensure the flow direction of the swirl after the two airflows are mixed, the notch 801 at the mouth of the inner cylinder 8 has the same rotation direction relative to the center axis of the cylinder, so that the hot air flow generated after combustion can flow to the top of the base 7.
