Shanghai New Machinery Factory builds a 4~b300’ millimeter Tata tower body ring weld joint at Zhejiang University’s 300,000 tons/year synthesis ammonia carbon monoxide, and adopts an electric infrared heat treatment new technology to use the cyclone tray for testing to obtain a lighter version. Jingjiang Jiangxi Institute of Technology adds float valve-shaped stone to the frit in the sieve plate------F In the vacuum distillation column with a diameter of 4.5 meters, it passes through the float valve tray. After the test, the effect is better than that of a steel plate net tower. Quantity than sieve?
