Description
Technical Field
The utility model relates to the technical field of seawater treatment, in particular to a structure for treating seawater by utilizing a degassing membrane group and a reverse osmosis membrane group.
Background
At present, cooling water and domestic water of a naval vessel are mainly prepared by adding a fresh water storage tank and an offshore desalination device, so that the naval vessel consumes power in actual operation, has limited supply time, high equipment requirement and larger limitation, and greatly influences the endurance time of the naval vessel. With the increase of the number of ships, the fresh water treatment capacity of the ships needs to be correspondingly improved so as to deal with long-time and long-distance operation, and a certain test is brought to the traditional water storage method and the seawater desalination device.
The seawater desalination technology by distillation is a distillation process, i.e. a process of heating seawater by distillation, condensing the evaporated steam to produce fresh water and simultaneously concentrating the seawater.
The seawater desalination distillation method mainly comprises two process methods of multi-stage flash evaporation and multi-effect distillation. The multi-stage flash evaporation is a seawater desalination process which preheats seawater by using steam, and then reduces pressure step by step to evaporate seawater rapidly to obtain fresh water. The multi-effect distillation is a seawater desalination process which utilizes steam to condense in a condensing tube so that seawater is gradually and multi-effect evaporated outside the condensing tube to obtain fresh water.
At present, a seawater desalination device utilizing a multi-stage flash evaporation method and the existing multi-effect distillation method has high energy consumption, so that the cost for reducing seawater desalination is limited; in addition, the fresh water produced in the seawater desalination process by the existing distillation method needs to be post-treated when being used for desalted water for boilers, and if the temperature is not increased in the operation process, serious scaling can occur.
The seawater may cause serious corrosion to pipelines, equipment and the like due to excessive oxygen content, so that the breeding of aerobic bacteria is aggravated, and ferroferric hydroxide precipitate is generated after reaction. Currently, there are three methods commonly used for seawater deoxygenation: gas stripping deoxidation, vacuum deoxidation and chemical deoxidation. The gas stripping deoxidation adopts a deoxidation technology of a deoxidation machine, but has the defects of large maintenance workload, large vibration of a machine set and the like. The core equipment of vacuum deoxidation is a vacuum deoxidation tower, which is limited by the height of an offshore platform layer, so that great inconvenience is brought to the arrangement of offshore equipment, and the oxygen content of effluent water is difficult to meet the requirement. Chemical deoxidation is carried out by adding a deoxidation agent, the treatment scale is large, the operation cost is greatly increased, and the method is not generally adopted.
