Portable equipment and process for producing water by sea water desalination

Abstract

The invention discloses portable equipment and a process for producing water by sea water desalination, belonging to the technical field of water treatment equipment and method. The portable equipment comprises a water taking module, an ultrafiltration module, a reverse osmosis module, a hardening and tempering module and a sterilizing module which are connected in sequence, wherein the ultrafiltration module comprises a group of ultrafiltration units which are mutually spliced; each ultrafiltration unit comprises a casing, a membrane sealing cover, membrane silks and a center tube; each membrane sealing cover is arranged inside the corresponding casing, and an inner cavity of each casing is divided into an upper water producing cavity and a lower filtering cavity; a discharging opening communicated with the center tube is formed in the top of each casing; a water producing port communicated with the upper water producing cavity is formed in the upper part of each casing; a water inlet communicated with the corresponding lower filtering cavity is formed in the lower end of each casing. The device disclosed by the invention is small in size, convenient in carrying and high in system adaptability; the water quality of incoming water and lower outgoing water of polluted seawater can meet the requirements of domestic drinking water.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment and methods, and in particular relates to a portable seawater desalination water production equipment and process. Background technique [0002] As the world's second largest economy, China is increasingly dependent on the ocean. However, with the increasing frequency of offshore operations, marine accidents caused by factors such as natural disasters and mechanical failures have occurred frequently, and the fresh water carried by life-saving facilities is limited, which cannot meet life-saving needs for a long time. Therefore, the development of emergency seawater treatment equipment is of great significance to marine emergency rescue. [0003] The discharge of coastal industrial waste, the accumulation of domestic garbage, the discharge of pollutants in the process of offshore oil exploitation and transportation, etc., have gradually increased the pollution of offshore waters....

AI Technical Summary

Problems solved by technology

However, the treatment effect of the front-end ultraviolet sterilizer is limited, and the rear-mounted ozone sterilizer has the influence of residual ozone, which has a safety impact on drinkers. The configured RO desalter is only suitable for surface water treatment and cannot adapt to the seawater environment.

[0006] It can be seen that the traditional process has poor adaptability to water quality, and the effluent water quality is unstable. Therefore, there is an urgent need for a seawater desalination equipment and seawater desalination water production process with strong water quality adaptability, stable desalinated water quality and easy operation.
