Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a multi-element circulating intelligent infrared heating system. Background Technology

[0002] A hot air furnace is a thermal energy device that burns fuel (coal, natural gas, biomass fuel) to generate heat and transfers that heat to the air, thus outputting high-temperature hot air. It is widely used in drying, heating, and industrial heating fields, such as grain drying, building material processing, and greenhouse heating, and is characterized by relatively low cost and stable heating. Hot air furnaces have two heating methods: one is to directly mix outside cold air with internal hot air and deliver it to the heating area; this method is only suitable for heating applications with low cleanliness requirements. The other method uses a heat exchanger to exchange heat between the hot air inside the furnace and the cold air passing through the heat exchanger before delivering it to the heating area; this method is suitable for heating applications with high cleanliness requirements, but it has lower heat transfer efficiency and higher heat loss. Infrared heating is a heating technology that uses infrared radiation to transfer heat. It emits electromagnetic waves of a specific wavelength through an infrared radiation source; when these electromagnetic waves irradiate the surface of an object, they are absorbed and converted into heat energy, thus achieving the heating target. Unlike traditional convection or conduction heating (such as coal-fired hot air furnaces), infrared heating is a form of radiative heat transfer, which has the advantages of fast heating speed and concentrated energy. Therefore, we combine far-infrared rays with hot air furnaces to provide a heating system with high heat transfer efficiency and low energy loss, making it more suitable for heating areas with high cleanliness requirements. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects and provide a multi-element circulating intelligent infrared heating system.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a multi-element circulating intelligent infrared heating system, comprising a combustion furnace, a heat exchange chamber, and an insulation shell. The combustion furnace is located in the middle, and the insulation shell covers the outside of the combustion furnace. A partition cylinder is also fitted inside the insulation shell. A heat exchange chamber is formed between the partition cylinder and the side wall of the combustion furnace, and a waste gas recovery chamber is formed between the partition cylinder and the insulation shell. A chimney is provided on the top of the combustion furnace, and the chimney is connected to the inlet of the waste gas recovery chamber. Both the partition cylinder and the side wall of the combustion furnace are made of thermally conductive metal, and the inner side of the partition cylinder and the outer side of the combustion furnace are coated with an infrared radiation coating.

[0005] Furthermore, the heat exchange chamber is provided with a spiral partition plate, which forms a spiral air duct in the heat exchange chamber. The bottom of the duct has a cold air inlet and the top has a hot air outlet.

[0006] Furthermore, the exhaust gas recovery chamber is provided with multiple vertical partitions, and an exhaust gas channel is provided between the vertical partitions and the top or bottom of the exhaust gas recovery chamber, with adjacent exhaust gas channels arranged alternately vertically.

[0007] Furthermore, the top of the waste gas recovery chamber is equipped with multiple high-pressure gas nozzles, which are located between two adjacent vertical partition plates.

[0008] Furthermore, the bottom of the waste gas recovery chamber is provided with multiple dust collection hoppers, the bottom of which is provided with a cleaning port and a sealing cover.

[0009] Furthermore, the combustion furnace is provided with a fuel inlet at the top and a screw feeder on one side, with the outlet of the screw feeder aligned with the fuel inlet.

[0010] Furthermore, the fuel inlet is equipped with an insulated door, and the top of the insulation shell is equipped with an electric telescopic rod, the two ends of which are respectively hinged to the top wall of the insulation shell and the insulated door.

[0011] The significant advantages of this invention are: the heat exchange chamber is directly installed on the outside of the combustion furnace, effectively reducing heat loss during gas transport. Furthermore, the high-temperature gas generated inside the combustion furnace is introduced into the waste gas recovery chamber, where heat exchange occurs simultaneously on both the inside and outside of the cold air, thereby accelerating the heat exchange rate and improving heat exchange efficiency. Simultaneously, the infrared radiation coating on the inside and outside of the heat exchange chamber further enhances the heating speed. Attached Figure Description

[0019] It is worth noting that the combustion furnace 1 has an air inlet (not shown in the figure) on one side or top to provide oxygen for combustion, and a blower is connected to this air inlet. The combustion furnace 1 has a gas recovery port at the top, and the outlet of the exhaust gas recovery chamber 5 is connected to the gas recovery port, so that the high-temperature exhaust gas after heat exchange returns to the combustion furnace, which is beneficial to fuel combustion and reduces heat loss.

[0020] It is worth noting that the chimney 6 is equipped with a high-temperature resistant guide fan to draw high-temperature gas into the waste gas recovery chamber 5.
