摘要： The present disclosure provides a phosgene synthesis and brine evaporation electrolysis integrated treatment process, comprising the following steps: 1) introducing premixed CO and chlorine to a primary phosgene synthesis tower to be synthesized into phosgene, the primary phosgene synthesis tower being provided with a heat transfer agent circulation space, and the heat transfer agent circulating in the heat transfer agent circulation space; 2) introducing the heat transfer agent, which absorbs reaction heat, in the heat transfer agent circulation space to a steam generator, exchanging heat with water to generate superheated steam, and returning the heat-exchanged heat transfer agent to the heat transfer agent circulation space for further absorbing the reaction heat generated by phosgene synthesis; 3) supplying the superheated steam to a brine evaporation concentration device, the brine evaporation concentration device performing evaporation concentration on brine by using the superheated steam as a heat source; and 4) electrolyzing the strong brine or dry salt obtained in step 3) to generate chlorine. The phosgene synthesis and brine evaporation electrolysis integrated treatment process can realize rational utilization of energy and resource utilization of effluent brine.

摘要： Provided are an apparatus and method for rapid cooling of a high temperature gas. The apparatus includes one or more cylindrical housings (001) connected to one another, a jacket (002) on an outer side of a housing, an inner cylinder (003) disposed at least in an interior of a first cylindrical housing, a heat insulation gasket (005), inner members (006), a corrosive high temperature gas inlet (N01) disposed on the heat insulation gasket (005), a gas and liquid phase outlet (N02) disposed at a bottom of the housing or a bottom of a last housing and a coolant inlet and outlet (N03-N05) connected to an interior of the jacket (002). The heat insulation gasket (005) seals the first cylindrical housing (001) and a top of the inner cylinder (003) in the interior of the first cylindrical housing (001). The inner members (005) are distributed along a wall of the housing (001), communicate an interior of the jacket (002) with an interior of the housing (001), and distribute a liquid in the interior of the jacket (002) to the interior of the housing (001). The method replaces a filter and a cooler and effectively reduces a risk of blockage when a solid-containing gas is cooled.
