Abstract

The invention relates to the field of energy recovery and utilization, aims to solve the problems of lack of fresh water, electric energy and low energy utilization in remote coastal areas, and provides a system and method for joint realization of cement production, seawater desalination and power generation in coastal areas. The joint realization method of cement production, seawater desalination and power generation in the coastal area is that the waste heat of the cement system passes through the heat exchange of AQC boiler, SP boiler and BP boiler to drive the working medium to do work on the power generation system, and the exhaust steam of the steam turbine enters the seawater desalination system for seawater desalination. The beneficial effect of the invention is that it is very suitable for remote seaside areas, can realize the organic combination of cement production, power generation and seawater desalination, has high energy utilization rate and can produce fresh water, cement and electric energy at the same time.

Description

technical field [0001] The invention relates to the field of energy recovery and utilization, in particular to a system and method for joint realization of cement production, seawater desalination and power generation in coastal areas. Background technique [0002] Water covers about 70% of the earth's surface, but as an important condition for the survival and development of life, only 2.5% of it is fresh water, and in this very small proportion of fresh water, only 0.3% can be directly taken. The problem of water shortage is sweeping the world. [0003] The economies of the Middle East, North Africa, and the coastal areas of West Asia are relatively backward. Resources such as cement and electricity are seriously lacking, and fresh water resources are even more scarce. The shortage of water resources affects the development of all aspects of society, not only limited to domestic water, agricultural production and industrial production are also limited by the distribution ...
