Problems solved by technology

[0003] At present, there are many patents on desalination of seawater by using the difference in air saturation and humidity, but they all focus on the evaporation of seawater and the mixing of air. There is no excellent solution for how to condense the moisture in the saturated humid air better.

Embodiment Construction

[0011] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] The steam inlet 1 of the present invention is connected to the external steam pipe, and the water vapor enters the first air intake layer 2, and then flows into the first layer of condensing pipes 3 to condense and release heat, and the condensed fresh water gathers at the bottom of the first condensing chamber 4, without The condensed steam enters the second air intake layer 7 from the small elbow 6, and then diverts into the second layer condensing pipe 8 to continue to condense and release heat, and the condensed fresh water collects at the bottom of the second condensing chamber 9. After several condensation processes, all the water vapor is finally condensed into fresh water. Cold seawater enters the first cold water chamber 12 from the cold seawater inlet 11, enters the second cold water chamber from the large elbow 13 after absorbing he...

Abstract

The invention discloses a fresh water condenser for sea water desalinization. According to the condenser, cold sea water serves as a cooling medium, a plurality of inner pipes and outer pipes which are sleeved in a pairwise manner serve as heat exchanger parts, saturated moist air is cooled, and saturation humidity difference of air at different temperatures is utilized to acquire fresh water.

Description

1. Technical field [0001] The invention relates to the technical field of seawater desalination and heat exchangers, in particular to a fresh water condenser, which is divided into multiple layers, and can condense water vapor into fresh water through multiple condensations, and at the same time make non-condensable gas and fresh water gas liquid separation. 2. Background technology [0002] Seawater desalination technology is a process of removing salt from seawater and obtaining fresh water through seawater desalination equipment. Seawater desalination methods are mainly divided into membrane method and distillation method. The equipment used in membrane desalination is simple to operate, the investment is relatively small, and the start-up time is short, but it must rely on electricity to work. Distillation mainly includes three technologies: multi-stage flash evaporation, low-temperature multi-effect and compressed air distillation. The first two technologies use steam...
