Abstract

The invention relates to the field of energy recycling, aims to solve the problems of fresh water shortage and low energy utilization rate in remote coastal areas, and provides a coastal area cement production and seawater desalination combined implementation system and method. The coastal area cement production and sea water desalination combined implementation method is characterized in that waste heat of a cement system is used for sea water desalination through heat exchange of an AQC boiler, an SP boiler and a BP boiler. The device has the beneficial effects that the device is very suitable for remote coastal areas, cement production and seawater desalination can be organically combined, the energy utilization rate is high, and fresh water and cement can be produced 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 and seawater desalination 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. While cement and other resources are seriously lacking, 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 and cost of water resources. W...
