The EA109 low-pressure reaction water condenser is an important equipment of the Tianji Group nitric acid plant, with a total length of 14.6 meters, a heat exchange area of ​​1,798 square meters, and a net weight of 48,055 kilograms. Its function is to rapidly condense the condensate in the nitrogen oxide. After 17 years of operation, about 1/3 of the 2020 heat exchange tubes of 2#EA109 low pressure reaction water condenser were blocked due to leakage, and the flow rate could not meet the design requirements, which directly affected the output of the nitric acid unit. Facing the reality, in the domestic can not find the heat exchange tube and tube plate to implement the inner hole welding manufacturer, the Tianji Group Machinery Factory developed the inner hole welding technology to manufacture the EA109 low pressure reaction water condenser.
The inner hole welding technology is very different from the ordinary welding technology. It is a very high-demand and extremely difficult technology in the equipment manufacturing. It is to insert a special welding torch into the heat exchange tube, and use the no-wire automatic argon arc welding method to heat the tube and tube. Plate welding prevents the liquid from directly scouring the weld. The machinery factory relies on its own strength and utilizes the EA109 low-pressure reaction water condenser manufactured by itself for 5 months. The innovations embodied in the internal hole welding form, the mechanical processing of the tube sheet, and the manufacturing process of the equipment. From the operation effect, the water pressure test and ammonia leakage test of the shell and tube process reached 100%, saving the group company 344,000 yuan.
