Manual-electric integrated axial plunger type seawater desalination machine and operation method

Abstract

The invention belongs to the technical field of seawater desalination equipment, and particularly discloses a manual-electric integrated axial plunger type seawater desalination machine and an operation method. The seawater inlet end, the energy recovery end and the power end of the seawater desalination machine are coaxially connected. The seawater inlet end comprises water inlet end plunger pumps which stretch out and draw back alternately, seawater raw water enters a pressurizing cavity through a raw water inlet pipe, the raw water in the cavity is pressurized through the action of a first ball shoe and a first swash plate, and then the raw water flows into a high-pressure seawater chamber; seawater in the high-pressure seawater chamber enters the fresh water chamber through a reverse osmosis membrane, and fresh water is supplied to the outside through a water production pipe; the high-concentration seawater which cannot pass through the reverse osmosis membrane enters the energy recovery cavity; the high-pressure concentrated water is recycled in the energy recycling cavity and used for assisting the energy recycling plunger pump to do circular motion on the second swash plate, and the concentrated water obtained after pressure relief is discharged to the outside under the action of the second flow distribution plate. The seawater desalination machine provided by the invention can be driven by electric power and manpower, and has the characteristics of small size, high integration level and light weight.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination equipment, and specifically discloses a flashlight-integrated axial plunger type seawater desalination machine and an operating method. Background technique [0002] At present, the preparation of seawater into potable fresh water can only be achieved by seawater desalination machines, but most large-scale seawater desalination devices rely on conventional energy sources, which require stable energy supply and long-term sites. For islands far away from the mainland and lack of energy, the power supply is limited Large-scale seawater desalination devices are not suitable for ships, offshore platforms, sea emergency rescue, field survival, scientific investigations, and other special occasions that require a small amount of short-term desalination. Not only are they poor in integration, poor in energy utilization, and large in size and weight. And can only rely on electric drive. Con...
