Abstract

The invention discloses an internal-combustion engine assisted sea water desalinization/poor-quality water purification method and a device thereof. The method comprises the following steps: 1, purifying high-temperature tail gas exhausted from a smoke exhaust pipe of an internal-combustion engine; 2, allowing the purified high-temperature tail gas to enter an evaporation chamber from the bottom of the evaporation chamber, meanwhile, heating raw water to form high-temperature raw water by the high-temperature tail gas, then spraying the high-temperature raw water from a spraying nozzle arranged in the middle of the evaporation chamber to form atomized high-temperature raw water, and carrying out explosive evaporation on the high-temperature tail gas and the atomized high-temperature raw water after meeting in the evaporation chamber to form high-temperature water vapor; 3, allowing the water vapor to pass through a condensate heat exchange chamber arranged on the upper part of the evaporation chamber to form condensate water; and 4, discharging the condensate water from a condensate water discharge pipe, and inputting the condensate water after being purified into a drinking water cabinet. The invention can make full use of the residual heat of cooling water and the tail gas of the internal-combustion engine, has high heat transfer efficiency, large water production rate and good effluent quality, can be used in the places or units which use the internal-combustion engine, and can also be used as pretreatment equipment of various reverse osmosis systems, therefore, the invention can be widely used in small and medium-sized boats such as ocean-going ships or ocean-going fishing-boats and the like which have a long time for sailing at sea.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a method and equipment for desalination of seawater and purification of inferior water. Background technique [0002] As we all know, it is very difficult to directly convert seawater, brackish water and other low-quality water into drinkable pure water. From a global perspective, there are many desalination methods. At present, reverse osmosis and electrodialysis are mostly used for desalination of brackish water, and distillation and reverse osmosis are mainly used for seawater desalination. Distillation (including multi-effect evaporation ME, flash evaporation FLASH and pressure steam distillation VC, etc.) is the process of heating brackish water or seawater to make it boil and evaporate, and then condensing the steam into fresh water. The main advantages of the distillation method are relatively simple structure, easy operation, and good fresh water quality. The disadvantage...
