Abstract

The invention relates to a solar seawater desalting system. A solar heat collector array is connected with an oil pipeline in a seawater evaporating tank, the inner side wall of the seawater evaporating tank is provided with an atomizing spray head, the atomizing spray head is connected with an unevaporated seawater outlet on the lower end of the seawater evaporating tank and a cold seawater outlet of a condenser through a cycling pump, and a steam outlet on the upper end of the seawater evaporating tank is connected with a steam inlet of the condenser. A coiled pipe is fully distributed inside the condenser, a water inlet of the coiled pipe is connected with a throttling valve for controlling the cold seawater inlet quantity, and a liquid water outlet on the lower end of the condenser is connected with a fresh water collecting device. The solar seawater desalting system does not need external energy, the radiation energy is converted to the heat for heating the working medium oil through the solar heat collector, and the heat is transferred to the seawater in the evaporating tank through the circulation of the oil inside the pipeline so as to heat the seawater. In addition, the atomizing spray head is also installed inside the evaporating tank, so that the heated area of the seawater is increased, and the evaporation of the seawater can be accelerated. The steam is condensed into the fresh water through the condenser, so that the desalting of the seawater can be realized.

Description

technical field [0001] The invention relates to the field of solar heat utilization and seawater desalination, in particular to a solar energy desalination system and device. Background technique [0002] The existing solar desalination systems and devices on the market are relatively large in size and extremely complicated, resulting in expensive devices, and the evaporation efficiency of seawater is not very high, resulting in waste of energy and materials. At present, there are many devices and methods for solar desalination of seawater, all of which use the heat of the sun to directly heat seawater. Many types of devices have been derived from this, but they are not perfect. Each device has its own advantages and disadvantages. Inadequacies. In addition to the efficiency of seawater desalination, the service life of the device is also the key. The device of the present invention starts from the two aspects of the efficiency of seawater desalination and the service lif...
