Mixed heating LNG gasifier
InactiveCN110319345ASuppress vibration phenomenonReduce heat pollutionFluid handledPressure vesselsStable stateEngineering
The invention provides a mixed heating LNG gasifier. The mixed heating LNG gasifier is composed of a hot water distributor, a finned tube, an LNG distribution tank, an NG gas collecting tank and the like. The hot water distributor comprises a hot water distribution box, a water inlet pipe, a hot water tank, a convex overflow plate, a cylindrical buffer, a buffer cover plate, a distribution plugboard, a trough type channel, an overflow plugboard and a drainage board, wherein the hot water tank is divided into a buffer area, a distribution area, an overflow area and a heat exchange area by the distribution plugboard and the overflow plugboard, the non-communication of the buffer area and the heat exchange area ensures that the hot water in the heat exchange area is in a stable state, so thathot water forms a uniformly-distributed hot water solution film on the outer surface of the finned tube through a flow guide plate. When the temperature in the daytime is high, the LNG is heated by taking air as a heat source. When the temperature at night is low, the LNG is heated by utilizing plant hot water, so that the gasification efficiency of LNG is improved.
