Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger air, and in particular to a heat exchanger air shroud assembly. Background Technology
[0002] High-temperature heat exchangers are devices used for cooling and heat recovery of large-volume, high-temperature flue gas. For example, in the color-coated steel sheet production line equipment of the steel industry, the gases generated during the spraying and curing process contain a large amount of flammable substances harmful to the environment (such as benzene, phenol, and resins). Directly releasing these gases into the atmosphere would cause significant harm to the surrounding environment, failing to meet air emission standards and relevant environmental protection requirements. Furthermore, with the dwindling resources of oil and coal, directly releasing these gases containing large amounts of flammable substances without utilization violates national energy conservation requirements and runs counter to the steel industry's policy of energy conservation and emission reduction. Therefore, the release of harmful gases into the atmosphere... Before application, the gases need to be rendered harmless. This typically involves collecting and extracting harmful gases, adding a certain proportion of coal gas, mixing them, and then incinerating them. During combustion, most harmful substances undergo chemical reactions to form harmless substances, ensuring the post-combustion gases meet relevant atmospheric emission standards. The resulting high-temperature flue gas (approximately 800°C) enters the tube side of a high-temperature heat exchanger for heat recovery, exchanging heat with fresh air from a blower. The fresh air passes through the tube side of the high-temperature heat exchanger, where its temperature is gradually heated to approximately 650°C to meet the curing requirements of the spray coating process. After heat exchange with the fresh air in the high-temperature heat exchanger, the temperature of the high-temperature flue gas gradually decreases to approximately 300°C. This high-temperature fresh air then enters the spray booth for the steel plate spray coating process. The resulting harmful gases are then mixed with coal gas and returned to the incinerator for combustion, creating a continuous cycle.
[0003] In traditional heat exchanger designs, the air shroud is a critical component, primarily responsible for preventing airflow loss during operation and ensuring the efficiency of forced convection heat transfer. However, traditional methods typically employ stamped sheet metal parts, which are then welded together. Over long-term use, this approach is prone to causing cracks at the weld seams due to impact, leading to breakage and severely impacting the heat exchanger's stability and lifespan. Furthermore, the fixed shroud design prevents adjustments to the number of heat exchange ducts based on actual production needs, limiting equipment flexibility and cost-effectiveness.

In this way, during long-term use, the weld seams are prone to cracks due to impact, which can lead to breakage and seriously affect the stability and service life of the heat exchanger.
[0005] The technical solution adopted in the embodiments of this application is as follows:
[0006] A heat exchanger shroud assembly includes a heat exchanger body, the body comprising a shell made of high-strength corrosion-resistant material and a heat exchanger tube bundle made of high-efficiency heat transfer material;
[0007] The air guide cover is made of high-strength plastic or lightweight alloy material using an integrated molding technology.

[0010] The air guide shroud contains multiple independent air duct components, each equipped with an independent adjustment mechanism to adjust the number and shape of the air ducts according to actual production needs.
[0011] A further technical solution is as follows: the shell adopts a double-layer structure, with the inner layer being heat-resistant stainless steel and the outer layer being carbon steel.
[0012] A further technical solution is that the heat exchange tube bundle uses high-efficiency heat transfer materials such as copper or aluminum.

Furthermore, this invention employs a quick-connect mechanism, facilitating rapid disassembly and assembly of the air guide shroud and the heat exchanger body, significantly saving maintenance and repair time and reducing maintenance costs. This is especially important for heat exchangers that require frequent cleaning or component replacement. The shell utilizes a double-layer structure, with an inner layer of heat-resistant stainless steel and an outer layer of carbon steel, enhancing its high-temperature resistance and corrosion resistance.
