Abstract

The invention discloses an energy-saving condensing box. The energy-saving condensing box comprises a box body, wherein the box body is internally provided with partitioning plates; the box body is divided into a front precooling box, a middle precooling box and a tail condensing box by the partitioning plates; the partitioning plate between the front precooling box and the middle precooling box and the partitioning plate between the middle precooling box and the tail condensing box are respectively provided with a flow guiding port, so that the front precooling box, the middle precooling box and the tail cooling box are mutually communicated; a tail-gas backflow pipe is arranged between the front precooling box and the tail condensing box; and the two ends of the tail-gas backflow pipe are respectively communicated with the tail condensing box. The energy-saving condensing box disclosed by the invention has the advantages that improvement is carried out on the basis of the original condensing box, heat exchange is carried out on tail gas and oil gas to be treated, cold amount in the tail gas is absorbed, the temperature of the oil gas to be treated is reduced, the cold amount needed by an oil-gas condenser is saved, the refrigerating load of the condenser is reduced and the energy consumption of the system is greatly reduced.

Description

technical field [0001] The invention relates to a condensation box, in particular to a condensation box used in an oil gas condensation recovery process, and belongs to the technical field of oil gas recovery devices. Background technique [0002] At present, the condensation oil and gas recovery technology is becoming more and more mature. The condensation oil and gas recovery equipment has good safety, high oil and gas recovery rate, environmental protection requirements, complete equipment, simple installation, automatic operation process, easy use and maintenance, and short investment recovery period. And other characteristics, has been widely used in refineries, gas stations and oil depots. Condensation method oil gas recovery technology is to use cascade refrigeration cycle to produce low temperature, reduce the temperature of oil gas in stages, the temperature of oil gas is reduced to -110 ℃ through the oil gas condenser, most of the light hydrocarbon gas is condensed...
