Modular and portable reverse osmosis seawater desalination integrated equipment and usage method

Abstract

The invention relates to the field of seawater desalination, and concretely relates to a modular portable reverse osmosis seawater desalination integration apparatus and a use method thereof. The apparatus is characterized in that a water intake pump, a bactericide dosing device, a filter, an ultrafiltration membrane assembly, a circulating pump, a reducing agent dosing device, a scale inhibitor dosing device, a high pressure pump, a reverse osmosis membrane assembly, a post-treatment dosing system, a cleaning water tank and a foldable water storage bag form a reverse osmosis seawater desalination system, the above devices except the water intake pump, the cleaning water tank and the foldable water storage bag all are fixedly installed in a trailer box body, and the whole body is a reverse osmosis desalination module. A pretreatment unit, a reverse osmosis desalination unit, a chemical dosing unit, a chemical cleaning unit and an electric and control unit are compactly, stably and reasonably integrated in the trailer with a closed box body trough a filter + ultrafiltration + reverse osmosis double membrane process, so the apparatus has the advantages of small size, light weight, flexible movement, and realization of transportation through aviation, highway, railways and ships.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a modular and movable reverse osmosis seawater desalination integrated equipment and a use method. Background technique [0002] Today, with the increasing economic development, most countries in the world are facing the common problem of water shortage. my country is a large oceanic country with many islands, and the coastal and central and western regions have extremely rich underground brackish water resources. Under the circumstances that underground water intake and cross-regional water transfer are subject to more and more conditions, the development and utilization of seawater and brackish water Desalination of seawater (brackish water) has become an important strategic way to increase revenue and reduce expenditure, and to solve the shortage of fresh water in my country. [0003] Reverse osmosis is currently a more economical and applicable seawater desalination techn...

Problems solved by technology

However, although the energy recovery device can greatly reduce the operating energy consumption and water production cost of the reverse osmosis seawater desalination device, due to the high price of the energy recovery device itself, the attached booster pump and high-pressure pipeline will increase the system investment cost and maintenance cost , which is obviously uneconomical for a load-type seawater desalination system with a small water production scale

Moreover, energy recovery devices are mostly used in large and medium-sized seawater desalination systems at present, and are not suitable for small vehicle-mounted seawater desalination systems

[0009] In addition, the Chinese utility model patent (publication number is CN201056504Y) and the Chinese utility model patent (publication number is CN201538698U), the above two patents do not mention the form of the car body and the power supply method of the seawater desalination system
