Abstract

The invention discloses a seawater desalinating device, relating to equipment with a small falling film evaporator and particularly relating to a device which carries out transverse-tube falling film evaporation by using solar energy. The seawater desalinating device comprises a seawater pretreatment system, an evaporator, a self-excited transverse-tube falling film evaporation-condensation device, a condenser, a grooved solar device and the like, wherein heat collected by the grooved solar device is transferred to the evaporator through heat exchange so as to supply a power source to the whole device. According to the seawater desalinating device, a pressure regulating device is arranged, so that the problem of control on difference of pressure inside the evaporator and the self-excited transverse-tube falling film evaporation-condensation device is solved; pretreated seawater is subjected to further filtering, so that the problem of pipeline blockage caused by seawater subjected to falling film is solved; and desalinated water collection tanks which are simple in structure and convenient in use are provided, so that the problem of low water yield caused by the fact that steam is condensed on an interior wall is solved. Compared with the prior art, the seawater desalinating device has the advantages that the effect on reducing the steam waste caused by wall condensation can be achieved, so that the water yield is increased.

Description

technical field [0001] The invention belongs to the technical field of seawater treatment devices, in particular to a seawater desalination device. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. The water quality is good and the price is becoming more and more reasonable. It can ensure stable water supply such as drinking water for coastal residents and supplementary water for industrial boilers. The process of obtaining fresh water from sea water is called desalination. [0003] At present, the global daily output of seawater desalination is about 35 million cubic meters, 80% of which is used for drinking water, which solves the water supply problem of more than 100 million people, that is, 1 / 50 of the world's population r...
