Marine heat pipe type seawater desalination device

Abstract

The invention belongs to the field of seawater desalination, and particularly relates to a marine heat pipe type seawater desalination device. The marine heat pipe type seawater desalination device is composed of a pressure gage, a liquidometer, heat pipes, a liquid distributor, a baffling plate, a snuffle valve, a cylinder body, a support, a one-way valve, a fresh water pump, a jet flow vacuum pump, a seawater pump, a partition plate, a demister and connecting pipelines. The marine heat pipe type seawater desalination device provided by the invention fully utilizes the advantage that the heat conductivity coefficient of a gravity heat pipe is high, adopts the heat of the cooling water of a ship engine as a heat source, and can greatly reduce the seawater boiling point under the vacuum environment created by the jet flow vacuum pump driven by a centrifugal pump; the seawater is distilled under the lower boiling point, thus the seawater desalination device provided by the invention has the advantages that the manufacture is simple, the structure is compact, the material consumption is less, the dual purposes that the cooling water of the ship engine is recycled and fresh water of a ship body is autarkical are achieved, the maintenance is convenient, the cost is low, the service life is long, and the installation space is small.

Description

Technical field [0001] This patent relates to a new type of single-effect low-temperature distillation seawater desalination device, which is used to produce fresh water from fishing boats, supply ships, passenger and cargo ships, coastal areas and islands where fresh water is scarce. Background technique [0002] At present, the shortage of freshwater resources has become a bottleneck restricting the development of my country's national economy and the improvement of people's living standards. Desalination is one of the fundamental ways to solve the shortage of water resources in coastal areas. Seawater desalination technology, also known as seawater desalination technology, is a process of separating salt and water in seawater. According to the separation principle and method, seawater desalination technology can be divided into two categories: phase change method and non-phase change method. The phase change method includes: distillation method (solar distillation method, low ...

AI Technical Summary

Problems solved by technology

But there are the following defects: 1. The plate heat exchanger used has poor sealing performance and is not suitable for producing fresh water for people to drink directly

2. The flow channel of the plate heat exchanger is small, which is not suitable for gas-gas heat exchange or steam condensation

But there are the following defects: 1. The outlet temperature of the diesel engine cooling water is 70-90°C, under normal pressure, it is difficult to distill seawater

2. Diesel engine flue gas contains a large amount of sulfur dioxide and sulfur trioxide, which is prone to dew point corrosion and the service life of the equipment is short
