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. It consists of pressure gauge, liquid level gauge, heat pipe, liquid distributor, baffle, relief valve, cylinder, support, one-way valve, fresh water pump, jet vacuum pump, seawater pump, partition, demister and connecting pipes composed of roads. This invention makes full use of the advantage of the high thermal conductivity of the gravity heat pipe, uses the heat of the ship engine cooling water as the heat source, and greatly reduces the boiling point of seawater in the vacuum environment created by the jet vacuum pump driven by the centrifugal pump. Distillation at the boiling point of the seawater desalination device makes the seawater desalination device simple to manufacture, compact in structure, and low in consumables. It achieves the dual purposes of recycling the cooling water of the ship's engine and self-sufficiency of the ship's fresh water. It has the advantages of easy maintenance, low cost, long life, and small installation space. .

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
