Cleaning Of Heat Exchanger

- Oct 17, 2017-

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 when there are many problems: can not completely clear the scale and other sediments, acid liquid on the equipment caused by corrosion of the formation of loopholes, residual acid on the material produced two times corrosion or corrosion, and eventually lead to replacement equipment, in addition Cleaning waste liquid is poisonous and requires large amount of funds for wastewater treatment. The new research and development of the equipment non-corrosive cleaning agent, which should have a better technology of the Fu Shi Tai cleaning agent, its high efficiency, environmental protection, safety, non-corrosive, not only good cleaning effect and no corrosion equipment, to ensure the long-term use of heat exchangers. Cleaning agent (special adding wetting agent and penetrating agent, can effectively remove the most stubborn scale (calcium carbonate) produced in water equipment, rust, grease, slime and other sediments, at the same time will not cause harm to the human body, will not iron and steel, copper, nickel, titanium, rubber, plastics, fiber, glass, ceramics and other materials to produce erosion, pitting, Other harmful reactions such as oxidation can greatly prolong the service life of the equipment. In the process of industrial production, sometimes due to improper operation caused by the sudden 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 that the production device can be normal operation, return to normal production status. Restore plant productivity. For example, chemical equipment scaling caused heat exchangers and other equipment transfer heat coefficient reduction, pipeline circulation area or the flow resistance increased, so that energy, material consumption increased, the production efficiency decreased significantly. At this time, by cleaning and descaling to restore production equipment production efficiency. Because of many reasons, heat exchanger equipment and pipeline lines will produce many such as coking, oil dirt, scale, sediment, corrosion products, polymers, fungi, algae, slime and other dirt. However, the dirt produced during the work will disable the equipment and pipeline lines, the device system will produce a decline in production, energy consumption, material increase and other adverse conditions, dirt corrosion is particularly serious when the process will be interrupted, the installation system forced to suspend production, directly resulting in various economic losses, and even the possibility of a vicious production accident. In the development of science today to completely avoid the production of dirt is almost impossible, so the cleaning of heat exchangers and other equipment has become an industry (such as: petroleum, chemical, electric power, metallurgical industries) in the production of an important link.
