Problems solved by technology

[0004] In recent years, in ships, along with the improvement of fuel consumption, the temperature of the cylinder liner cooling water for cooling the internal combustion engine has risen, for example, it has gradually reached 90°C or higher, and a large amount of salt and scale precipitated due to the evaporation of seawater adhere to the seawater flow In the heat exchanger that has been overheated, there is a problem that not only the decrease in water production due to the decrease in thermal conductivity cannot be avoided, but also the maintenance to remove said salt and scale requires huge work

Abstract

A water making method and a water making device are disclosed. The water making device is provided with a heat exchanger and a condenser, wherein the heat exchanger heats sea water through cooling water cooling an internal combustion engine, reduces the pressure of the sea water to be lower than the atmospheric pressure and generates water vapor; the condenser cools the vapor generated by the heat exchanger to generate distilled water; the condenser comprises a bypass channel connecting the upstream side and the downstream side of the heat exchanger; and the cooling water in the downstream side of the heat exchanger is returned to the cooling water in the upstream side through the bypass channel.

Description

technical field [0001] The invention relates to a water production device and a water production method. Background technique [0002] Conventionally, for cooling internal combustion engines such as diesel engines mounted on ships, for example, in a water production device that uses cylinder liner cooling water at about 80°C as a heat source, the circulation channel of the cylinder liner cooling water of the internal combustion engine is provided with a pressure reduction to An indirect heat exchanger below atmospheric pressure. In the heat exchanger, the cylinder liner cooling water of the internal combustion engine is used as a heat source to heat seawater extracted from the sea to generate water vapor, followed by gas-liquid separation, And the water vapor after gas-liquid separation is condensed, and fresh water is produced (for example, refer patent document 1). [0003] Patent Document 1: Japanese Patent No. 3923820 [0004] In recent years, in ships, along with the ...
