Filtering and heating device for water used for yachts and ships

Abstract

The invention relates to a filtering and heating device for water used for yachts and ships; the filtering and heating device is applied to the field of kitchen appliances used for the yachts or the ships. The device comprises a front filter, a first front filter element, a first reverse osmosis (RO) filter element, a pressure barrel, a second front filter element, a second RO filter element, granular active carbon and a drinking water outlet which are sequentially installed from a water inlet end; the pressure barrel is externally connected with the drinking water outlet. The product adopts atwo-stage reverse osmosis filtration technology so as to greatly improve the filtration precision, and separates domestic water from drinking water; the device adds a heating function to the drinkingwater, and can realize stepless adjustment of temperature from normal temperature to 98 DEG C, thus largely avoiding the risk of personal safety and property loss which are caused by boiling water onthe yachts while meeting the different temperature demands of crews.

Description

technical field [0001] The invention relates to a water filtering and heating device for yachts and ships, which is applied to the field of kitchen appliances for yachts. Background technique [0002] my country has more than 18,000 kilometers of coastline, more than 6,500 large and small islands and more than 24,000 lakes. With the improvement of people's living standards and the upgrading of consumption concepts, yachts, as a Western-style lifestyle, have become more and more popular in recent years. People's favor, it can be predicted that the kitchen appliances specially used for yachts will also show a blowout growth. [0003] In modern navigation, fresh water is still a relatively scarce and precious resource. The fresh water used by the yacht mainly comes from its own fresh water, which is expensive for the yacht and increases its own weight, which affects its maneuverability. Moreover, due to the limited space of the yacht, it is often impossible to provide a larger ...

AI Technical Summary

Problems solved by technology

The fresh water used by the yacht mainly comes from its own fresh water, which is expensive for the yacht and increases its own weight, which affects its maneuverability. Moreover, due to the limited space of the yacht, it is often impossible to provide a larger fresh water storage compartment. Lake water purification or seawater desalination has become an important way to ensure the continuous and stable supply and replenishment of drinking water for yachts

[0004] The existing seawater filtration devices are mainly distillation type and reverse osmosis type, and the most widely used is the distillation type. The heat source mainly consists of electric energy, hot water, steam, and waste heat from the exhaust of gas turbines. Commonly used distillation type seawater desalination devices mainly use diesel engine cooling water Steam is used as a heat source for seawater desalination, and its use conditions are limited by the working conditions of the main engine. Seawater desalination can only be performed when the main power unit is working, and the system is complex and difficult to manage

The reverse osmosis type has the characteristics of low energy consumption, simple operation and high desalination efficiency, but because the total dissolved solids (Total dissolved solids, abbreviated TDS) in seawater is generally high, sometimes as high as 20,000-30,000ppm, even if it reaches more than 90% The desalination rate and the TDS of the desalinated water are also 2,000-3,000ppm, far exceeding the national drinking water standard. It can only be called "life-saving water" and far from "healthy water".

And at present, whether it is distillation or reverse osmosis, it can only provide filtering function for yachts or ships, but cannot realize heating function

[0005] After searching, the current "seawater desalination" devices or systems are generally large in size and heavy in weight, and are not suitable for use on sea yachts. Some systems require additional heating of seawater, which will cause a shortage of offshore energy supply.
