Semi-automatic production method and equipment for preparing ice and desalinating seawater by natural energy resources

Abstract

The invention discloses a semi-automatic production method and equipment for preparing ice and desalinating seawater by natural energy resources. The equipment comprises a plurality of terrace-shaped icing ponds arranged in a vertical and horizontal manner, and is characterized in that seawater is poured into the icing ponds at the temperature below 0 DEG C, unfrozen water at the bottom of the icing ponds is discharged after the seawater ices to 1-2cm, and the sea ice is smashed to slump into the bottom of the ponds; an electric lifting gate of each icing pond is opened, the smashed sea ice slides down along the sloping surface of the bottom of the pond, and falls into a container after impacting an ice blocking wall; a drainage valve at the lower part of the container is opened, the sea ice melts and ices repeatedly along with the temperature difference between day and night, and salted ice water is discharged; the drainage valve is closed when the salinity of the discharged salted ice water is detected to be less than 1 per mill, and the ice in the container melts into fresh water by integral bask in natural state. The invention utilizes gravity to lead the ice to smash automatically to slide into a vehicle through a sloping surface, thus heavy physical labor in the link that ice is collected and transported into the icing pond is omitted in the prior art.

Description

Technical field [0001] The invention relates to a production method and equipment for seawater desalination, in particular to a semi-automatic production method and equipment for using natural energy to make ice and desalinate seawater. Background technique [0002] At present, the indirect desalination method of seawater desalination (mainly the method of producing fresh water from sea ice) is gradually attracting people's attention. Among them, the method of using natural energy to make sea ice and sea ice to make fresh water is most in line with the requirements of environmental protection and is most worthy of promotion. But so far, the above-mentioned method has not been used for large-scale factory production, and large-scale factory production must have corresponding mechanized or automated equipment, but there has been no relevant research report so far. [0003] For example, the patent CN1686839A (the method of using natural cold source to make ice to desalinize br...

Problems solved by technology

[0006] If the process of picking and transporting ice requires a lot of heavy physical labor, then this kind of production can only be workshop-style production, and it is difficult to have the development prospect of large-scale factory production
