Problems solved by technology

The biggest problem when cleaning is to dismantle the whole seawater desalination device, then soak it with water, neutralize it with a neutralizer, and rinse it with fresh water. Since disassembly and assembly are troublesome, cleaning is usually done in ship repair How to find a simple cleaning method becomes a demand

Embodiment Construction

[0033] Such as Figure 2 to Figure 4 As shown, the present invention is figure 1 On the basis of the seawater desalination system used by ships, a cleaning part is added, and the cleaning part mainly includes a liquid storage tank 11 and an infusion pipeline 12 . Wherein, the two ends of the infusion pipeline 12 communicate with the liquid outlet end of the liquid storage tank 11 and the liquid injection end of the heat exchange cylinder 3 in the existing marine seawater desalination system respectively, and the infusion pipeline 12 communicates with the liquid storage tank 11 One end is the liquid inlet, and the end connected with the heat exchange barrel is the liquid outlet. The liquid outlet of the infusion pipeline extends to the inside of the heat exchanger and is arranged on the upper side of the copper tube group 17 inside the heat exchanger. In addition, an infusion regulating switch 15 is installed on the infusion pipeline 12, and the flow rate of the liquid in the ...

Abstract

The invention provides a marine seawater desalination system with a cleaning function. A cleaning part comprises a liquid storage tank and a liquid delivery pipe. Two ends of the liquid delivery pipe respectively communicates with a liquid outlet end of the liquid storage tank and a liquid injection end of a heat exchange cylinder. A cleaning liquid and a neutralizing solution are injected into a copper pipe set through the liquid delivery pipe, and is discharged through a residue discharge valve provided at the bottom of the copper pipe set; clear water is injected into the copper pipe set through the liquid delivery pipe, and is used for flushing the copper pipe set. A method for applying the system comprises the following steps: an acidic cleaning liquid is injected into the copper pipe set, and is discharged after 2-3h of soaking; a sodium hydroxide solution is injected into the copper pipe set, and is discharged after 2-3h of soaking; and clear water is injected into the copper pipe set inside the heat exchange cylinder for flushing, such that a cleaning process is completed. According to the invention, the entire system does not need to be disassembled during the cleaning process. The system has the advantages of convenient application, low cost, and good cleaning effect. With the system, operator labor intensity is greatly reduced.

Description

technical field [0001] The invention belongs to the field of seawater desalination, in particular to a marine seawater desalination system with cleaning function and a cleaning method. Background technique [0002] At present, there are seawater desalination devices on ships at home and abroad. The desalination method is almost always distillation. There are two common distillation methods, namely vacuum boiling type and vacuum flash type. Among them, vacuum boiling type is more common. Now we will briefly explain the vacuum The working principle and working process of the boiling seawater desalination device. Working principle: Seawater desalination by distillation is to make use of the characteristics that salt is almost insoluble in low-pressure water vapor to heat and vaporize seawater, and then condense the water vapor generated by seawater to obtain fresh water with little salt content and distilled water. The purpose of using vacuum is to reduce the boiling point of ...
