Description

Technical Field

[0001] This utility model relates to the field of natural gas heating, and in particular to a natural gas heating and combustion supply equipment. Background Technology

[0002] Natural gas heating and combustion equipment is a system that generates heat energy by burning natural gas and transfers the heat to a medium such as air or water, thereby providing a stable heat source. Its working principle is as follows: natural gas mixes with air in a burner and ignites, producing a high-temperature flame. The heat is transferred to the circulating medium (such as air or water) through a heat exchanger, and then a fan or pump transports the heated medium to the area requiring heat, achieving functions such as heating, drying, or process heating.

[0003] During the combustion of natural gas, the natural gas is ignited by an igniter to generate high-temperature heat, and the gas is converted into carbon dioxide and water vapor. However, the combustion efficiency of natural gas is relatively low and the combustion is incomplete. At the same time, after the natural gas combustion is completed, there is a large amount of high-temperature gas inside the tank, which is relatively inefficient to cool naturally. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a natural gas heating and combustion supply equipment that improves the combustion efficiency of the device and the cooling efficiency after the device has completed its heating process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Natural gas heating and combustion equipment for supplying hot gas includes:

[0007] A support tank for support, with an upper traction frame fixedly connected to the top of the support tank, a transmission pipe fixedly connected to the top of the upper traction frame, a vortex fan fixedly connected to the middle of the bottom of the support tank, a transmission sleeve fixedly connected to the top of the inner side of the support tank, a combustion tank fixedly connected to the bottom of the transmission sleeve, an air inlet pipe fixedly connected to the right side of the support tank, a support plate fixedly connected to the middle of the bottom of the combustion tank, the inner side of the air inlet pipe fixedly connected to the inside of the support plate, and a staggered air inlet assembly installed on the outside of the combustion tank to ensure sufficient internal air to accelerate combustion efficiency.

[0008] A transmission air plate is used to support the bottom of the tank. A support plate is fixedly connected to the left side of the tank. A cooling air pump is fixedly connected inside the support plate. A cooling pipe is fixedly connected to the output end of the cooling air pump. The bottom end of the cooling pipe is fixedly connected to the left side of the transmission air plate. A cooling channel is installed on the inner wall of the tank to enable rapid cooling of the heating equipment after use.

[0009] Furthermore, the cooling channel includes a cooling ring groove opened on the inner wall of the supporting tank, and multiple traction rings are uniformly fixedly connected inside the cooling ring groove from bottom to top, and multiple cooling slots are uniformly opened on the inner side of the supporting tank.

[0010] Furthermore, the staggered air intake assembly includes multiple traction arc plates fixedly connected around the outside of the combustion tank, and multiple air intake slots are opened around the outside of the combustion tank, with the outer side of each air intake slot corresponding to the inner side of the traction arc plate.

[0011] Furthermore, the multiple traction arc plates are staggered among themselves.

[0012] Furthermore, a reinforcing disc is fixedly connected to the upper outer side of the combustion tank, and the reinforcing disc is fixedly connected to the inner side of the supporting tank body.

[0013] Furthermore, an igniter is fixedly connected to the front bottom of the supporting tank, and the ignition end of the igniter penetrates the interior of the combustion tank.

[0014] Furthermore, the external dimensions of the plurality of traction rings gradually decrease from bottom to top.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, natural gas is transmitted to the interior of the combustion tank through an air inlet pipe, external air is accelerated into the interior of the supporting tank by a vortex fan, and air is drawn into the interior of the combustion tank by a traction arc plate, thereby increasing the oxygen content inside the combustion tank, improving the combustion effect of the device, and accelerating the combustion efficiency.

[0017] In this invention, external air is accelerated into the cooling pipe by a cooling air pump, and discharged upward into the cooling ring groove by a transmission air plate. The air is also drawn into the support tank by multiple traction rings, which agitates the high-temperature gas inside, thereby improving the cooling efficiency after the device has completed heating and enhancing the safety of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a natural gas heating and combustion hot gas supply device, comprising: a support tank 1 for support, an upper traction frame 2 fixedly connected to the top of the support tank 1, a transmission pipe 3 fixedly connected to the top of the upper traction frame 2, a vortex fan 9 fixedly connected to the middle of the bottom end of the support tank 1, an 11 fixedly connected to the top of the inner side of the support tank 1, a transmission sleeve 10 fixedly connected to the inner side of the 11, a combustion tank 14 fixedly connected to the bottom end of the transmission sleeve 10, an air inlet pipe 15 fixedly connected to the right side of the support tank 1, a support plate 20 fixedly connected to the middle of the bottom end of the combustion tank 14, and an inner side of the air inlet pipe 15 fixedly connected to the support plate 20. Inside the combustion tank 14, an offset air intake assembly is installed on the outside to ensure sufficient internal air and accelerate combustion efficiency. The offset air intake assembly includes multiple traction arc plates 13 fixedly connected around the outside of the combustion tank 14. Multiple air intake slots 19 are opened around the outside of the combustion tank 14. The outer sides of the air intake slots 19 correspond to the inner sides of the traction arc plates 13. The multiple traction arc plates 13 are staggered. A reinforcing plate 12 is fixedly connected to the upper outside of the combustion tank 14. The outside of the reinforcing plate 12 is fixedly connected to the inner side of the supporting tank body 1. An igniter 8 is fixedly connected to the front bottom of the supporting tank body 1. The ignition end of the igniter 8 penetrates the inside of the combustion tank 14.

[0026] Natural gas is delivered to the combustion tank 14 through the intake pipe 15. At the same time, the vortex fan 9 is activated to pressurize the external air and introduce it into the support tank 1. The air is divided inside the support tank 1: one part enters the combustion chamber directly through the bottom hole of the combustion tank 14, and the other part flows along the outer wall of the combustion tank 14. After being guided by the traction arc plate 13, it enters the combustion tank 14 through the air inlet 19. After the igniter 8 ignites the mixed gas, the accelerated air flow significantly increases the oxygen concentration in the combustion tank 14, making the natural gas burn more completely. This design, by optimizing the air supply path and mixing efficiency, not only improves the combustion effect and heating performance, but also significantly improves the overall combustion efficiency.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The transmission air plate 7 is used to support the bottom of the tank 1. A support plate 5 is fixedly connected to the left side of the support tank 1. A cooling air pump 4 is fixedly connected inside the support plate 5. A cooling pipe 6 is fixedly connected to the output end of the cooling air pump 4. The bottom end of the cooling pipe 6 is fixedly connected to the left side of the transmission air plate 7. A cooling channel is installed on the inner wall of the support tank 1 to achieve rapid cooling of the heating equipment after use. The cooling channel includes a cooling ring groove 16 opened on the inner wall of the support tank 1. Multiple traction rings 17 are evenly fixedly connected inside the cooling ring groove 16 from bottom to top. Multiple cooling slots 18 are evenly opened on the inner side of the support tank 1. The external dimensions of the multiple traction rings 17 gradually decrease from bottom to top.

[0028] After the heating is finished, the system starts the cooling air pump 4, which pressurizes and delivers external cold air through the cooling pipe 6 to the transmission air plate 7. The air flows upward and enters the cooling ring groove 16 through the slot at the bottom of the support tank 1. Under the guidance of multiple traction rings 17, a vortex is formed. The inclined structure on the inner side of the traction ring 17 accelerates the air and enters the interior of the support tank 1 through the cooling slot 18, where it undergoes forced convection heat exchange with the high-temperature gas. This synergistic effect of multi-stage guidance and forced circulation significantly improves the cooling efficiency of the device, ensures that the safe temperature is reached quickly, and effectively guarantees the safety and reliability of the equipment.

[0029] Working principle: Natural gas is discharged into the combustion tank 14 through the intake pipe 15. Simultaneously, the vortex blower 9 is activated, accelerating the external air and drawing it into the supporting tank 1. The air flows rapidly within the supporting tank 1, causing a split. Part of the air enters the combustion tank 14 through the bottom hole, while the other part flows outside the combustion tank 14 and is drawn into the intake slot 19 by the traction arc plate 13, thus entering the combustion tank 14. The igniter 8 ignites the gas inside the combustion tank 14, burning the natural gas. The accelerated air intake also raises the pressure inside the combustion tank 14. The internal oxygen content is increased to improve the completeness of natural gas combustion and improve combustion efficiency. After the heating of the device is completed and the heating is turned off, the cooling air pump 4 is started to accelerate the external air into the interior of the cooling pipe 6, thereby accelerating the air into the interior of the transmission air plate 7. The air is discharged to the upward side and enters the interior of the cooling ring groove 16 through the groove at the bottom of the support tank 1. The air flows from bottom to top and passes evenly through multiple traction rings 17. The air is accelerated through the inclined surface on the inner side of the traction ring 17 and enters the interior of the support tank 1 through the cooling groove 18, thereby agitating the high-temperature gas inside the support tank 1 and improving the cooling efficiency of the device.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
