How to Clean a Tubular Heat Exchanger

Firstly, the tubular heat exchanger is a widely used type of heat exchanger. It is a type of inter wall heat exchanger. Mainly composed of shell, tube plate, heat exchange tube, head, and baffle. So in use, it is necessary to clean the tube heat exchanger in a timely manner to ensure the extension of the equipment's service life.

Long term operation of tubular heat exchangers can lead to equipment being blocked by scale, which will reduce efficiency, increase energy consumption, and shorten service life. If scale cannot be removed in a timely manner, there is a risk of equipment maintenance, shutdown, or scrapping and replacement. For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, and chemical cleaning (acid washing) have encountered multiple problems when cleaning heat exchangers: they cannot completely remove sediment such as scale, which causes corrosion to the equipment. The remaining acid causes secondary corrosion or corrosion under the scale, ultimately leading to equipment replacement. In addition, the cleaning waste liquid is toxic and requires a large amount of funds for wastewater treatment.

At this point, an efficient and environmentally friendly cleaning agent can be used to avoid the above situation. It has the characteristics of high efficiency, environmental protection, safety, and no corrosion. It not only has a good cleaning effect but also does not corrode the equipment, ensuring the long-term use of the air compressor. Cleaning agents and penetrating agents can effectively remove stubborn scale (calcium carbonate), rust, oil, mud, and other sediment generated in water consuming equipment, without causing harm to the human body or causing other harmful reactions such as corrosion, pitting, oxidation, etc. to materials such as steel, copper, nickel, titanium, glass, ceramics, etc., greatly extending the service life of the equipment.
