Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, and particularly relates to a natural gas combustion heating equipment. Background Art

[0002] Natural gas is mainly composed of gaseous low-molecular hydrocarbons and non-hydrocarbon gases; using natural gas as an energy source can reduce the consumption of coal and petroleum, thus greatly improving the environmental pollution problem; as a clean energy source, it can reduce sulfur dioxide and dust emissions by nearly 100%, reduce carbon dioxide emissions by 60% and nitrogen oxide emissions by 50%, and help reduce the formation of acid rain, slow down the earth's greenhouse effect, and fundamentally improve the environmental quality. Therefore, in urban life, there are more and more natural gas combustion heating equipment.

[0003] The patent with the publication number CN213901244U proposes a natural gas combustion heating equipment, including a heating box, a water tank and a heating and heating module. There is a water tank on the upper side inside the heating box, an arc-shaped plate on the lower side inside the heating box, several copper pipes are embedded at the upper end of the arc-shaped plate, the upper ends of the copper pipes penetrate through the water tank, and several heat conduction fins are arranged at the upper part of the copper pipes and inside the water tank. There is a ceramic fireproof layer on the lower side of the inner wall of the heating box, a combustion heating module is arranged on the lower side inside the heating box, and a water supply pipe is arranged at the right end of the water tank.

[0004] When the above case is in use, the arc-shaped plate is heated by a gas nozzle, and then the heat is conducted to the cold water inside the water tank through a plurality of copper pipes vertically connected to the arc-shaped plate and the heat conduction fins outside the copper pipes. However, in actual work, after the cold water enters the water tank, it will directly flow to the bottom and then into the water supply pipe. If the device needs to be continuously turned on to provide hot water, it cannot fully heat the cold water, and when the gas burns in a closed space, a large amount of air is required. The device is not provided with a reasonable air supply structure, resulting in too low air supply efficiency of the device, making the gas prone to incomplete combustion and reducing the practicability of the device.

[0005] Therefore, the utility model provides a natural gas combustion heating equipment to meet the needs. Content of the Utility Model

[0006] The utility model provides a natural gas combustion heating equipment, which can solve the problems in the prior art that when in actual work, after the cold water enters the water tank, it will directly flow to the bottom and then into the water supply pipe. If the device needs to be continuously turned on to provide hot water, it cannot fully heat the cold water, and when the gas burns in a closed space, a large amount of air is required. The device is not provided with a reasonable air supply structure, resulting in too low air supply efficiency of the device, making the gas prone to incomplete combustion and reducing the practicability of the device.

[0007] To solve the above technical problems, the present utility model provides the following technical solutions:

[0024] The following describes in detail a natural gas combustion heating device provided by the present utility model in conjunction with the drawings and specific embodiments; meanwhile, it should be noted here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art can also adopt other alternative methods.

[0025] As Figures 1 to 3As shown in the figure, an embodiment of the present utility model provides a natural gas combustion heating device, which includes a main body 1. At the top of the inner cavity of the main body 1, a heat insulation frame 2 is fixedly connected. Inside the heat insulation frame 2, a heat conduction frame 3 is fixedly connected. At the bottom of the heat conduction frame 3, a plurality of heat transfer plates 15 are fixedly connected. The bottom ends of the heat transfer plates 15 penetrate out of the heat insulation frame 2 and are fixedly connected to a heating cover 5. A flow guiding assembly 4 is used to guide and slow down the flow of cold water. The flow guiding assembly 4 is connected to the heat conduction frame 3. The number of the flow guiding assemblies 4 is four, which are evenly distributed inside the heat conduction frame 3 from top to bottom and are arranged in a staggered and inclined manner. The flow guiding assembly 4 includes a flow guiding plate 401 fixedly connected to the heat conduction frame 3. At the top of the flow guiding plate 401, a plurality of arc-shaped plates 402 are fixedly connected. Inside the arc-shaped plates 402, a plurality of shunt holes 403 are opened. At the bottom end of the inner cavity of the main body 1, an ignition device 6 is fixedly connected. At the top of the ignition device 6, a plurality of flame spraying pipes 7 are fixedly connected, which are located directly below the heating cover 5. The heating cover 5 is fixedly connected to the main body 1. At the bottom of the ignition device 6, a gas pipe 12 is fixedly communicated, and its bottom end penetrates out of the bottom end of the main body 1. At the top end of one side of the main body 1, a water inlet pipe 13 is fixedly communicated. The heat conduction frame 3, the flow guiding assembly 4, the heat transfer plates 15, and the heating cover 5 are all made of high heat conduction materials.

[0026] When hot water needs to be supplied by the device, the ignition device 6 is started, natural gas is received through the gas pipe 12, and ignition combustion is carried out below the heating cover 5 through the flame spraying pipes 7. The heat generated by the combustion is transferred to the inside of the heat conduction frame 3 through the heating cover 5 and the heat transfer plates 15. Cold water enters the heat conduction frame 3 through the water inlet pipe 13. Under the guidance of the flow guiding plate 401 and the arc-shaped plates 402, it flows along an inclined path, is dispersed through the shunt holes 403, and gradually flows through a plurality of flow guiding plates 401 until it reaches the bottom end of the heat conduction frame 3. While the cold water is flowing, heat is transferred to the cold water through the heat conduction frame 3 and the flow guiding assembly 4 to heat it into hot water.

[0027] The flow guiding plate 401 is installed at a specific angle of inclination to guide the cold water to a preset flow track, avoiding the direct flow of the cold water to the bottom end after entering the heat conduction frame 3. As the cold water moves forward along the flow guiding plate 401, it will encounter the arc-shaped plates 402, which not only conform to the natural bending trend of the water flow but also cleverly open a plurality of shunt holes 403 inside them. These shunt holes 403 are like miniature shunt stations, which divide the cold water into smaller water flows, enabling each drop of water to come into more sufficient contact with the surfaces of the heat conduction frame 3 and the flow guiding assembly 4. In this process, the flow rate of the cold water is greatly slowed down, while its contact area and time with the heat conduction frame 3 and the flow guiding assembly 4 are significantly increased, thus achieving an efficient heating effect. When the cold water undergoes this series of guiding and dispersion, it will finally converge at the bottom of the heat conduction frame 3. At this time, the water temperature has been significantly increased. Subsequently, this warm hot water will flow along the established path to the water outlet pipe 14, enabling the device to ensure the stability of the outlet water temperature and the quality of the hot water even when it needs to continuously operate to supply hot water.

[0028] As shown Figures 1 to 4 in the figure, a number of air inlets 9 are provided at the bottom ends on both sides of the main body 1. A number of flow pipes 10 are fixedly connected inside the main body 1. A number of air guide rings 11 are fixedly connected inside the flow pipes 10. On both sides of the main body 1 and outside the diversion holes 403, barrier covers 8 are fixedly connected. The number of air inlets 9 and flow pipes 10 on one side of the main body 1 is three each. The number of air guide rings 11 inside the same flow pipe 10 is three. Air guide holes are provided inside the air guide rings 11 and are bent towards the inside of the main body 1. At the bottom end of the heat conduction frame 3 away from the water inlet pipe 13, a water outlet pipe 14 is fixedly communicated, and it extends to the outside of the main body 1.

[0029] To ensure the full combustion of the gas, external air enters through the air inlets 9, flows into the flow pipes 10, and the air guide rings 11 guide and accelerate the flow of the air, supplying air to the inside of the device. After the hot water flows into the bottom of the heat conduction frame 3, it flows out through the water outlet pipe 14, continuously supplying hot water.

[0030] After the air enters the flow pipe 10, it will encounter the air guide rings 11, causing the air to experience multiple processes of entering from a large space into a small space inside the flow pipe 10. This spatial change not only increases the complexity of the air flow but also makes the air continuously compressed and released during the flow process, further accelerating its flow speed. At the same time, this design also helps to evenly distribute the air around the heating cover 5, providing more sufficient oxygen support for the combustion of the gas.

[0031] The working principle provided by the present utility model: When the device needs to supply hot water, the ignition device 6 is started, natural gas is received through the gas pipe 12, and ignition combustion is carried out below the heating cover 5 through the flame spraying pipe 7. The heat generated by the combustion is transmitted to the inside of the heat conduction frame 3 through the heating cover 5 and the heat transfer plate 15. Cold water enters the heat conduction frame 3 through the water inlet pipe 13, and under the guidance of the flow guiding plate 401 and the arc-shaped plate 402, it flows along an inclined path, is dispersed through the diversion holes 403, and gradually flows through multiple flow guiding plates 401 until it reaches the bottom end of the heat conduction frame 3. While the cold water is flowing, heat is transferred to the cold water through the heat conduction frame 3 and the flow guiding component 4 to heat it into hot water. To ensure the full combustion of the gas, external air enters through the air inlets 9, flows into the flow pipes 10, and the air guide rings 11 guide and accelerate the flow of the air, supplying air to the inside of the device. After the hot water flows into the bottom of the heat conduction frame 3, it flows out through the water outlet pipe 14, continuously supplying hot water.

[0032] The above ignition device 6 is publicly known in the prior art in the present utility model and will not be described in detail here.

[0033] The utility model covers any alternatives, modifications, equivalent methods and solutions made to the essence and scope of the utility model; in order to enable the public to have a thorough understanding of the utility model, specific details are described in detail in the above preferred embodiments of the utility model, and those skilled in the art can fully understand the utility model without the description of these details.

[0034] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
