Condensate water supercharging device based on steam injection and condensate water system

Abstract

The embodiment of the invention provides a condensate water supercharging device based on steam injection and a condensate water system. The condensate water supercharging device comprises a condensate water input channel, a first steam input channel and a condensate water output channel. The outlet ends of the condensate water input channel and the first steam input channel are communicated withthe inlet end of the condensate water output channel; condensed water is introduced into the condensed water input channel so as to form an output condensed water fluid at the outlet end of the condensed water input channel; the first steam input channel is used for introducing steam with preset pressure, the outlet ends of the first steam input channel are arranged around the outlet end of the condensate water input channel in the same direction so as to form an output steam fluid, and the steam fluid is in contact with the condensate water fluid; according to the device, the operation is stable and reliable, the full utilization of steam energy is realized, the noise is low, the simultaneous heating and pressurizing of condensed water are realized, the compactness of the overall structure of a condensed water system is ensured, and the working efficiency of a ship power system is improved.

Description

technical field [0001] The invention relates to the technical field of ship power, in particular to a condensed water pressurization device and a condensed water system based on steam injection. Background technique [0002] The power system is the core component of ships, offshore platforms and other marine devices, providing sailing power, living energy and electricity for marine devices. The power system of marine devices is different from that of land equipment. It not only needs to take into account the limited space and load-bearing capacity of the ship, but also needs to control the noise level of the cabin based on the comfort of the crew on the ship, so that the compactness and vibration of the power system Noise puts forward higher requirements. [0003] The steam Rankine cycle is one of the common cycles in the ship power system, and the condensation system is one of the key components of the steam Rankine cycle. The condensate system includes a heat trap, a dea...
