Abstract

The invention relates to a seawater desalting technology, in particular to a portable seawater desalting device and a water purifying cup including the same in order to solve the problems that an existing seawater desalting device is complex in structure, high in cost, serious in membrane pollution and oxidation and large in waste water amount, and cannot be miniaturized.A plurality of three-way capillary tubes form a circle, a perfluor sulfoacid membrane is wound around the outer side of the circle for a circle and is located on the junction of a sweater inlet segment, a desalted water outlet segment and a concentrated water outlet segment, small holes are formed in the side wall of each three-way capillary tube, and the small holes are located in the contact positions of the perfluor sulfoacid membrane and the three-way capillary tubes.A concentrated water reflux tank is used for containing water dropping from the concentrated water outlet segment.A positive electrode of a power source is built in the seawater inlet segment through a small hole in the side wall of the seawater inlet segment, and a negative electrode of the power source is fixed to the perfluor sulfoacid membrane.The water purifying cup including the portable seawater desalting device comprises a cup body and the portable seawater desalting device.The portable seawater desalting device is high in purifying efficiency, low in energy consumption, low in waste water ratio, convenient to carry and suitable for desalting sweater, and scale-free desalting is achieved.

Description

technical field [0001] The invention relates to seawater desalination technology. Background technique [0002] The main methods currently used for seawater desalination are: distillation, reverse osmosis and electrodialysis, but all have some disadvantages. [0003] Distillation is a method of boiling seawater by heating it to vaporize it, and then condensing the steam into fresh water. Distillation seawater desalination technology is the first desalination technology put into industrial application. It is characterized by being applicable even in seawater environments with severe pollution and high biological activity, and the produced water has high purity. However, the distillation method also has many disadvantages in practical applications, such as high operating costs for large-scale equipment, complex equipment structure, difficult operation, and the need to be used in conjunction with power stations. However, a small seawater desalination device that can be used a...
