Description
Technical Field
[0001] The utility model relates to the technical field of heat recovery devices, in particular to a heat recovery device for fertilizer production. Background Art
[0002] In the process of producing fertilizers, boilers are needed to provide heat. Boilers will produce exhaust gas in the process of heating. These exhaust gases themselves have a high temperature. If they are discharged directly, a lot of heat energy will be wasted. In order to prevent the waste of heat, the boiler exhaust gas will be input into the heat recovery device to recover the heat of the exhaust gas. The hot water generated in the recovery process passes through the air compressor, and the heat is collected for granulation, which reduces energy consumption and improves energy utilization.
[0003] The exhaust gas with waste heat generated by the boiler not only has a high temperature, but also contains some acidic and harmful gases. When these gases enter the air inlet pipe through the external pipe, they will cause corrosion to the connection between the external pipe and the air inlet pipe and accelerate the aging of the inner wall of the pipe, which will cause the connection between the air inlet pipe and the external pipe to loosen. In severe cases, the external pipe and the air inlet pipe may be separated from each other. Utility Model Content
