[0002] In the field of organic isocyanate synthesis, gas phase phosgene reaction process is gradually mature, and has realized large-scale production in toluene diisocyanate (TDI) and aliphatic isocyanate (ADI) field. But as a new industrial technology, gas phase phosgene process still has many technical details that need to be improved. Among them, the quenching design of high-temperature reaction mixed gas is one of the key links in the gas phase phosgene reaction process, and its basic principle is to rapidly cool and absorb the reaction mixed gas in the axial extension pipeline at the bottom of the gas phase reactor in the form of quenching liquid spray, so as to achieve the purpose of separating and collecting reaction products.

Compared with the existing design, the quenching cooler can install more atomizing nozzles on the same length of vertical section, improve the quenching absorption effect, the atomizing nozzle is fixed on the inner wall of the quenching cooler, each atomizing nozzle is configured with a dredger in the axial direction. The dredger is installed at the intersection of the central axis reverse extension line of the atomizing nozzle and the outer wall of the quenching cooler.
