Title:
船舶エンジンの排気余熱を利用する間接低温マルチエフェクト海水淡水化システム
Document Type and Number:
Japanese Patent JP6404955
Kind Code:
B2
Abstract:
The present invention provides an indirect low-temperature multi-effect seawater desalination system by using waste heat of exhaust gas of a ship engine. The system comprises a low-temperature multi-effect seawater desalination apparatus, a low-temperature steam generating apparatus, and a waste heat recovery apparatus disposed in an exhaust pipeline of the engine. Pretreated and preheated seawater enters the low-temperature multi-effect seawater desalination apparatus for desalination processing, wherein a first-effect gas inlet and a condensation water outlet in the low-temperature multi-effect seawater desalination apparatus are connected to the low-temperature steam generating apparatus by means of a pipeline, and the low-temperature steam generating apparatus is connected to the waste heat recovery apparatus by means of an ascending pipe and a descending pipe. In the present invention, on the premise that the waste heat recovery apparatus is not corroded by acidic dews, the waste heat recovery apparatus makes full use of the waste heat of exhaust gas of the engine, so that the waste heat recovery apparatus can provide a heat source to the low-temperature multi-effect seawater desalination apparatus so as to generate steam or hot water at a temperature required by the low-temperature multi-effect seawater desalination apparatus.
