Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 to Figure 4 shown. A solar desalination device, including a crown-shaped solar collector 1 composed of hexagonal light-transmitting glass 6, a circular sump with "concave" groove 2, a stainless steel shell condensing heat exchanger 3, and a stainless steel connecting pipe 4. Stainless steel serpentine coil 5. The crown-shaped solar collector 1 is buckled upside down in the "concave" groove of the circular sump 2; the serpentine coil 5 is assembled in the condensation heat exchanger 3; the connecting pipe 4 connects the crown-shaped solar collector 1 with the condensation heat exchanger The heaters 3 are connected together.

[0024] Each piece of hexagonal light-transmitting glass 6 on the crown-shaped solar heat collector 1 can accurately focus the sunlight projected on its surface on the liquid surface of the circular pool 2 .

Abstract

The invention discloses a solar energy sea water desalinating device which comprises a sea water heater and a condensing heat exchanger. The solar energy sea water desalinating device is characterized in that the sea water heater is composed of a sea water collection tank and a crown solar heat collector covered on the sea water collection tank, the condensing heat exchanger leads in sea water by a sea water inlet and leads the sea water into the sea water collection tank by a sea water supply pipe communicated with the sea water collection tank; the crown solar heat collector is composed of a plurality of transmitting glass; each transmitting glass is a biconvex mirror, and sunlight projecting the surface of each transmitting glass is respectively focused on sea water in the circular seawater collection tank, the top of the crown solar heat collector is connected with the condensing heat exchanger by a communicating pipe, and stream evaporated by the sea water collection tank is guided into the condensing heat exchanger to be output through a fresh water pipe after being condensed into fresh water.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a solar seawater desalination device. Background technique [0002] 97.2% of the water on the earth is undrinkable seawater, fresh water only accounts for 2.8%, 70% of which exists in the form of ice and snow in the south and north poles, and the water actually supplied to human life activities is less than 0.8% of the total. [0003] "Water is the oil of the 21st century". The United Nations predicts that fresh water will become the world's most stressed natural resource in the 21st century. Currently, seawater desalination technologies include natural freezing, artificial freezing, solar desalination, nuclear desalination, multi-stage flash (MSF) and reverse osmosis (RO) technologies. Among them, the most widely used technologies are multi-stage flash (MSF) and reverse osmosis (RO). [0004] The production capacity of multi-stage flash (MSF) accounts for 56% of the total pro...
