For a long time, traditional cleaning methods such as mechanical methods (scraping, brush), high-pressure water, chemical cleaning (pickling), etc. in the heat exchanger cleaning, there are many problems: can not completely remove scale and other sediments, acid and corrosion of equipment caused by the formation of loopholes, residual acid on the material produced two times corrosion or corrosion, resulting in the replacement of equipment, in addition, Clean waste liquid is poisonous, need large amount of money to carry on waste water treatment. New research issued on the equipment corrosion-free cleaning agent, which should have a better technology with the blessing of the grams of detergent, its high efficiency, environmental protection, safety, non-corrosive, not only good cleaning effect and no corrosion of equipment, to ensure long-term use of heat exchangers. Cleaning agent (special wetting agent and penetrating agent) can effectively remove the most stubborn scale (calcium carbonate) produced in water equipment. Rust, grease, sticky mud and other sediments, at the same time will not cause harm to the human body, steel, copper, nickel, titanium, rubber, plastics, fiber, glass, ceramics and other materials to produce erosion, pitting,
Oxidation and other harmful reactions, can greatly prolong the service life of the equipment. In the process of industrial production, sometimes due to improper operation caused by the unexpected situation of individual equipment or local pipeline line scaling, plugging, affecting the normal operation of production. For this situation, the main is the rapid removal of dirt, to ensure the normal operation of production equipment, restore normal production status. Recovery unit production efficiency. For example, chemical equipment scaling caused heat exchangers and other equipment transfer heat coefficient of heat, reduce the flow of the pipeline area or increase the flow resistance, so that energy, things and other consumption increased, productivity significantly decreased.
At this time by cleaning and descaling to restore production equipment production efficiency. For many reasons, heat exchanger equipment and pipeline lines will produce a lot of such as coking, oil dirt, scale, sediment, corrosion products, polymers, fungi, algae, slime and other dirt. However, the dirt produced at work will invalidate the equipment and piping lines, the installation system will produce a decline in production, energy consumption, increase in material and other adverse conditions, especially serious dirt corrosion will also make the process interruption, the installation system is forced to stop production, directly causing a variety of economic losses, and even the possibility of vicious production accidents. In the scientific development of today to completely avoid the emergence of dirt is almost impossible, so, heat exchangers and other equipment cleaning will become the industry (such as: oil, chemical, electric power, metallurgical industries) in the production of an indispensable important link.
