Description

A device for cleaning the inner wall of the condensation pipe with high-pressure water jet

technical field

The utility model relates to a device for cleaning the inner wall of a condensation pipe by using high-pressure water jet technology, and belongs to the technical field of material surface treatment.

Background technique

The condenser tube in the condenser is mainly used for the circulating flow of cooling water, so as to achieve the purpose of refrigeration. After the widely used condensing tube works for a period of time, deposits such as scale and dirt begin to precipitate in the tube, and the thickness continues to increase with time, resulting in a decrease in heat exchange efficiency and affecting the cooling effect. Usually, chemical methods are used to clean the inner wall, which is costly, and the cleaning liquid also pollutes the environment and has a certain corrosion effect on the condenser tube, which is prone to leakage.

In 2009, the Chinese Patent Publication No. 201463705U "Condenser Condenser Tube Inner Wall Cleaning Device" disclosed a condenser condensate tube inner wall cleaning device, including a condensate tube. The end of the condensate tube is connected with a brush chamber. The tube is provided with brushes composed of brush caps, bristles, and stainless steel shafts. The invention can automatically clean the condenser tubes without chemical cleaning and keep the tubes free of scale and deposits. But, the hairbrush of this patent is easy to wear and tear and block pipeline.

In 2008, the Chinese Patent Publication No. 201297887 "Condenser Tube Descaling Device" disclosed a condenser tube descaling device, which fits on the condenser tube so that the descaling block can scrape off the scale on the condenser tube. This patent also has the problem of clogged pipes.

Among the currently disclosed information, the main problems are: the use of chemical cleaning technology is easy to pollute the environment and corrode the condensation pipe, and the use of brushes and descaling blocks has high cost and easy blockage of pipelines.
