Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to a waste heat recovery evaporator. Background Art

[0002] In the copper smelting acid conversion process, the flue gas temperature generated in the upstream process is relatively high, some process gases are 560-575 degrees Celsius, some process gases are 600-628 degrees Celsius, while the flue gas temperature required by the downstream equipment is between 415-425 degrees Celsius. The flue gas has the characteristics of large pressure fluctuations (0-35KPa), large flue gas concentration fluctuations and large flue gas flow fluctuations; therefore, the flue gas temperature needs to be reduced to the required temperature, and the recovered heat requires energy-saving utilization.

[0003] After searching, the application number "202222803210.7" discloses a flue gas waste heat recovery evaporator, which belongs to the technical field of evaporators, including an evaporator body, the left end of the evaporator body is fixedly installed with an air inlet assembly, and the right end of the evaporator body is fixedly installed with an air outlet assembly; the upper end of the evaporator body is installed with a steam assembly; the steam assembly includes a cross pipe, a steam generating cylinder, a safety valve, a straight pipe, a water injection pipe and heat-conducting fins; the lower end of the steam generating cylinder is fixedly installed on the evaporator body, and the inner top of the steam generating cylinder is fixedly connected with a number of evenly distributed heat-conducting fins, and the lower end of the heat-conducting fins extends into the interior of the evaporator body. Through the above method, the first anti-corrosion inner cylinder and the second anti-corrosion inner cylinder of the utility model are both made of existing high-aluminum fire-resistant and acid-resistant materials, which can improve the corrosion resistance, reduce the degree of corrosion of the air inlet and outlet of the evaporator, and extend its service life.

[0004] When this technical solution is in use, the air inlet and outlet on it need to be installed with the pipeline to allow the gas to enter and exhaust the evaporator, but there is no suitable fixing device on it, and then it needs to be fixed with a fixing device that is compatible with the equipment at the pipeline and the connection port.
