Hydrophilic evaporation tank for tubular solar desalination device

Abstract

The invention provides a hydrophilic evaporation tank for a tubular solar desalination device, which belongs to the technical field of sea water desalinization and water treatment. The hydrophilic evaporation tank comprises a water tank, a hydrophilic ceramic membrane, catchment wings and a catchment device, wherein a cylindrical shell serves as the water tank, and an opening is axially formed onthe upper edge of the shell; through holes are uniformly and axially distributed on the outer edges on two sides at the top of the water tank; honeycomb holes are uniformly distributed on the outer surface of the water tank, and the hydrophilic ceramic membrane is uniformly adhered on the outer surface of the water tank; grooves are symmetrically arranged below the outer surface sides of the water tank, and the arc catchment wings equilong with the water tank are welded on the outer edges of the grooves; one ends of the catchment wings are semi-closed, and the other ends of the catchment wings are closed; the catchment device is arranged at one end of the water tank, and a drain hole is formed on the catchment device; and holes on the catchment wings are communicated with an inner cavity of the catchment device. The hydrophilic evaporation tank utilizes the hydrophilic performance of the hydrophilic ceramic membrane and the honeycomb hole structure to enhance the heat energy utilization efficiency of the tubular solar desalination device, thus enhancing water production rate and shortening system water outlet time.

Description

technical field [0001] The invention relates to a device for improving the performance of a tubular solar seawater desalination device, which belongs to the technical field of seawater desalination and water treatment. In particular, it relates to a device for improving the fresh water production capacity of a tubular solar seawater desalination device by using a special material and a corresponding structure. Background technique [0002] The problem of scarcity of fresh water resources has become a factor that cannot be ignored affecting the production and development of human society. Seawater desalination technology can solve this problem well to a certain extent. Considering the energy saving and environmental protection as well as the cost of construction and operation, the use of solar energy for seawater desalination has attracted more and more attention. Patent CN102167413A discloses a multi-effect tube solar seawater desalination device, which has attracted widesp...

Problems solved by technology

But at the same time, it also has certain defects. In the general tubular solar desalination device, when the seawater is evaporating and condensing, only the part of the casing facing the opening of the water tank can use the latent heat of evaporation. Seawater is heated unevenly, which to a certain extent also greatly reduces the utilization efficiency of heat energy and reduces the effect of seawater desalination
