DEVICE FOR STEAM CONDENSATION FROM STEAM-GAS MIXTURE

摘要

FIELD: energy.SUBSTANCE: invention can be used in oil and gas and chemical plants for condensation of vapour phase of vapour-gas mixture. Device for steam condensation from steam-gas mixture has a cylindrical housing with heat exchange tubular elements and unions to feed and discharge and condensate, as well as cooling agent circulation system. Heat exchange tubular elements are combined into upper and lower heat exchangers, between which a intermediate cavity, tubular elements of the upper heat exchanger are arranged concentrically and are fixed between the grates are shifted relative to their axes through angle ϕ, the value of which corresponds to the formula: ϕ=d/r, where d - inner diameter of tubular element, r- radius of the axes of the middle row of tubular elements relative to the centre of the array. Above the top heat exchanger there is a mixing chamber communicated with pump and equipped with steam-gas mixture supply nozzle and spraying nozzles, and under the lower heat exchanger is located accumulative cavity, in the lower part of which there are drain union, as well as branch pipe for supply of cooled condensate, connected with nozzles. In the intermediate cavity condensate level sensors are installed, which are connected with control unit and drain union. Cooling agent circulation system comprises coolant feed and discharge pipes in the upper and lower parts of the upper and lower heat exchangers respectively, pump and cooling unit, the annular space of heat exchangers are intercommunicated.EFFECT: invention allows to increase heat exchange processes using condensate as cooling medium.1 cl, 2 dwg
