Multiple-effect generator and absorption type power-air exhaust jet refrigeration electricity generating circulation system

Abstract

The invention relates to power acting through the seawater temperature difference, in particular to a multiple-effect generator and an absorption type power-air exhaust jet refrigeration electricity generating circulation system. The multiple-effect generator comprises a shell, an inlet, a backflow opening, a dilute solution outlet, warm water pipes and liquid distributors; the inlet, the backflowopening and the dilute solution outlet are formed in the shell, the inlet comprises a falling film evaporation inlet, a rising film evaporation inlet and a hydraulic filling evaporation inlet, the falling film evaporation inlet, the rising film evaporation inlet, the backflow opening and a gas outlet are formed in the top surface of the shell, the hydraulic filling evaporation inlet and the dilute solution outlet are formed in the bottom surface of the shell, the warm water pipe and the liquid distributors are arranged in the shell, multiple layers of liquid distributors are arranged in the shell from top to bottom at intervals, the warm water pipes are arranged above the liquid distributors, and at least one warm water pipe is arranged below the last liquid distributor. The ocean temperature difference, that is the widely-existing low-grade heat energy, can be used for driving an absorption type working medium to carry out cold-electricity combined supply circulation, and energy multi-stage use can be achieved independently without solar energy, waste heat, and afterheat.

Description

technical field [0001] The invention relates to the use of seawater temperature difference energy to do work, in particular to a multi-effect generator and an absorption type power-pumping jet refrigeration power generation cycle system. Background technique [0002] With the development of the world economy and the increase of energy consumption, energy and environmental issues have become a hot issue of common concern all over the world. Low-grade heat energy comes from a wide range of sources, such as solar energy, ocean energy, low-grade waste heat generated in the production process of enterprises, Even the heat emitted by the flue gas is difficult to be utilized. Among them, the ocean temperature difference energy has the unique advantages of large reserves and stable quality of heat sources, and has great development prospects. [0003] The essence of the organic Rankine ocean temperature difference power generation technology is to use the solar energy stored in the...
