Description

Technical Field

[0001] This utility model relates to the field of heat energy recovery technology, and in particular to a heat energy recovery device. Background Technology

[0002] Industrial silicon is obtained by reducing silicon oxide (SiO2) with carbon in a submerged arc furnace at a high temperature of around 1800℃. Industrial silicon is a dark gray solid with a metallic luster, and is therefore often called metallic silicon. Industrial silicon is an important basic material in modern industry and is widely used in various sectors of the national economy, including metallurgy, chemical industry, electronic information, optoelectronic technology, aerospace, photovoltaic new energy, and shipbuilding. Industrial silicon is an indispensable basic material in modern industry, including high-tech industries.

[0003] For example, Chinese Patent Publication No. CN220270153U describes a high-efficiency heat recovery device, belonging to the field of heat recovery technology. It includes a heating box, with a water inlet pipe and an air inlet pipe fixedly installed at the upper end of the heating box. The air inlet pipe extends through the outer wall of the heating box to the inner top wall. A spiral tube is fixedly installed at the lower end of the air inlet pipe, and an air outlet pipe is fixedly installed on the side of the spiral tube away from the air inlet pipe. The air inlet pipe allows air to enter the spiral tube, while the air outlet pipe allows air to exit the spiral tube. The water inlet pipe adds water to the interior of the heating box, allowing the hot air in the spiral tube to heat the water.

[0004] However, in the above-mentioned scheme, it is not convenient to clean the surface of the spiral tube during use. After long-term use, a large amount of dirt and scale will adhere to the surface of the spiral tube. These dirt and scale will affect the heat exchange efficiency of the spiral tube, resulting in a low heat recovery and utilization effect. Utility Model Content
