Description

Technical Field

[0001] This utility model belongs to the field of alcohol-based fuel technology, specifically relating to a detonation catalytic heating device. Background Technology

[0002] In the wave of energy structure transformation towards cleaner and lower-carbon energy, alcohol-based fuels, as a clean energy source with advantages such as wide availability of raw materials and low emissions, have become an important part of the new energy industry. Their application demand in multiple fields such as industrial heating, transportation, and residential heating continues to rise.

[0003] However, the heat exchange efficiency of existing catalytic heating devices is not fully utilized, resulting in waste. Furthermore, uneven mixing of internal gas and fuel may lead to incomplete catalytic combustion, a problem that needs to be solved by those in the field. Utility Model Content

[0004] The purpose of this invention is to provide a detonation catalytic heating device for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a detonation catalytic heating device, including a catalytic tank, a mixing chamber is opened inside the catalytic tank, a heat exchange cylinder is arranged in the middle of the catalytic tank, a number of fins are horizontally arranged in the middle of the heat exchange cylinder along the center line, two sets of air inlet pipes pass through the bottom of the heat exchange cylinder, the ends of the two sets of air inlet pipes are connected to the mixing chamber, an air outlet is arranged at the front end of the mixing chamber, a rotating shaft is arranged on the opposite side of the air outlet and rotatably connected to the right end of the catalytic tank, a mixing fan is arranged in annularly on the outer side of the rotating shaft, a number of partitions are arranged in annular intervals between the heat exchange cylinder and the catalytic tank, and a catalyst module is arranged between two adjacent partitions.

[0006] The present invention further explains that the center line of the heat exchange cylinder is arranged to coincide with the center line of the catalytic tank in the same direction, and the outer diameter of the heat exchange cylinder is smaller than the inner diameter of the catalytic tank.

[0007] The present invention further explains that the fins are arranged horizontally and equidistantly on both sides of the inner wall of the heat exchange cylinder, and the opposite sides of the fins on both sides are respectively connected to the outside of the air inlet pipe on that side.

[0008] This utility model further illustrates that the two sets of air inlet pipes form a connected structure between the air mixing chamber and the air outlet, and the air outlet is set in a conical shape.

[0009] The present invention further explains that the mixing fan forms a rotating structure with the catalyst tank through the rotating shaft, and the mixing fan is inclined and annularly arranged on the outer wall of the rotating shaft.

[0010] This utility model further illustrates that the end of the catalytic tank with the mixing fan is arranged in an arc shape.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: By setting up a mixing chamber, two sets of inlet pipes transport the gas to be reacted to the mixing chamber. The conical outlet can accelerate the gas flow rate and form a concentrated airflow when the gas flows out, which initially improves the uniformity of gas mixing. Inside the arc-shaped end of the right end of the catalytic tank, the mixing fan with an inclined ring distribution on the outside of the rotating shaft rotates under the push of the gas, and performs secondary stirring on the gas flowing out of the outlet. By using the shearing and guiding effect of the inclined fan blades, the gas stratification is broken, avoiding local gas concentration unevenness and achieving full mixing at the gas molecule level.

[0012] By setting up a heat exchange cylinder, the heat exchange cylinder in the middle of the catalytic converter and the fins arranged horizontally at equal distances inside form a high-efficiency heat exchange system. The center line of the heat exchange cylinder coincides with the center line of the catalytic converter, and the outer diameter is smaller than the inner diameter of the catalytic converter. This ensures that there is enough space around the heat exchange cylinder to accommodate the catalyst module and the reaction gas, while maximizing the heat exchange area. The two sides of the fins are connected to the outside of the inlet pipe. On the one hand, the heat inside the heat exchange cylinder can be transferred to the inlet pipe through the fins to preheat the incoming cold gas, increase the initial temperature of the gas, and reduce the energy consumption for reaction start-up. On the other hand, when the catalytic reaction generates a large amount of heat, the heat exchange cylinder and fins can quickly absorb the excess heat, preventing the temperature inside the catalytic converter from becoming too high and damaging the catalyst module, while also realizing heat recovery.

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] A detonation catalytic heating device, as shown in the figure, includes a catalytic tank 1, a mixing chamber 2 inside the catalytic tank 1, a heat exchange cylinder 3 in the middle of the catalytic tank 1, several fins 4 horizontally arranged along the center line in the middle of the heat exchange cylinder 3, two sets of air inlet pipes 5 passing through the bottom of the heat exchange cylinder 3, the ends of the two sets of air inlet pipes 5 connecting to a mixing chamber 6, an air outlet 7 at the front end of the mixing chamber 6, a rotating shaft 8 rotatably connected to the right end of the catalytic tank 1 on the opposite side of the air outlet 7, a mixing fan 9 circumferentially arranged on the outer side of the rotating shaft 8, several partitions 10 circumferentially spaced between the heat exchange cylinder 3 and the catalytic tank 1, and a catalyst module 11 arranged between two adjacent partitions 10.

[0016] The centerline of the heat exchange cylinder 3 is set to coincide with the centerline of the catalyst tank 1 in the same direction, and the outer diameter of the heat exchange cylinder 3 is smaller than the inner diameter of the catalyst tank 1. The centerline of the heat exchange cylinder 3 coincides with the centerline of the catalyst tank 1, and the outer diameter is smaller than the inner diameter of the catalyst tank 1. This ensures that there is enough space around the heat exchange cylinder 3 to accommodate the catalyst module 11 and the reaction gas, and also maximizes the heat exchange area.

[0017] The fins 4 are arranged horizontally and equidistantly on both sides of the inner wall of the heat exchange cylinder 3, and the opposite sides of the fins 4 on both sides are respectively connected to the outside of the air inlet pipe 5 on that side. The heat exchange cylinder 3 in the middle of the catalytic tank 1 and the fins 4 arranged horizontally and equidistantly inside constitute a high-efficiency heat exchange system.

[0018] The two sets of air inlet pipes 5 form a connected structure between the mixing chamber 6 and the air outlet 7, and the air outlet 7 is set in a conical shape. The two sets of air inlet pipes 5 deliver the gas to be reacted to the mixing chamber 6. The conical air outlet 7 can accelerate the gas flow rate and at the same time make the gas form a concentrated airflow when it flows out, thus initially improving the uniformity of gas mixing.

[0019] The mixing fan 9 forms a rotating structure with the catalytic tank 1 via the rotating shaft 8, and the mixing fan 9 is inclined and annularly arranged on the outer wall of the rotating shaft 8 to perform secondary stirring on the gas flowing out from the outlet 7. By utilizing the shearing and guiding effect of the inclined fan blades, the gas stratification is broken up, and local gas concentration unevenness is avoided.

[0020] The mixing fan 9 at one end of the catalytic tank 1 is set in an arc shape. The arc-shaped end of the right end of the catalytic tank 1 can reduce gas flow resistance, avoid the formation of vortices in the gas at the end that cause pressure accumulation, and reduce the risk of equipment operation. The mixing fan 9 adopts an inclined ring design, which can not only efficiently stir the gas, but also balance the gas pressure through rotation, avoiding excessive local pressure that could cause equipment damage.

[0021] Working principle: First, two sets of air inlet pipes 5 transport the gas to be reacted to the mixing chamber 6. The conical air outlet 7 can accelerate the gas flow rate and at the same time form a concentrated airflow when the gas flows out, which initially improves the uniformity of gas mixing. Inside the arc-shaped end of the right end of the catalytic tank 1, the mixing fan 9, which is inclined and annularly distributed on the outside of the rotating shaft 8, rotates under the push of the gas, and performs secondary stirring on the gas flowing out from the air outlet 7. By using the shearing and guiding effect of the inclined fan blades, the gas stratification is broken, local gas concentration is avoided, and the gas molecules are fully mixed. Next, the heat exchange cylinder 3 in the middle of the catalytic converter 1 and the fins 4 arranged horizontally and equidistantly inside form a high-efficiency heat exchange system. The centerline of the heat exchange cylinder 3 coincides with the centerline of the catalytic converter 1, and its outer diameter is smaller than the inner diameter of the catalytic converter 1. This ensures that there is sufficient space around the heat exchange cylinder 3 to accommodate the catalyst module 11 and the reaction gas, while maximizing the heat exchange area. The two sides of the fins 4 are connected to the outside of the inlet pipe 5. On the one hand, the heat inside the heat exchange cylinder 3 can be transferred to the inlet pipe 5 through the fins 4 to preheat the incoming cold gas, increase the initial temperature of the gas, and reduce the reaction start-up energy. On the one hand, when the detonation catalytic reaction generates a large amount of heat, the heat exchange cylinder 3 and the fins 4 can quickly absorb the excess heat, preventing the catalyst module 11 from being damaged by excessively high temperature inside the catalyst tank 1, and at the same time realizing heat recovery. Several partitions 10 arranged in an annular interval between the heat exchange cylinder 3 and the catalyst tank 1 divide the catalyst module 11 into independent catalytic areas, so that the mixed gas can be evenly distributed to each catalytic area and fully contact the catalyst module 11, avoiding problems such as gas flow obstruction and excessively rapid local catalyst activity decay caused by concentrated accumulation of catalyst.
