The Technique Of Heat Exchanger Cleaning Dirt And Grease!
Along with the development of the industry, "heat exchanger" now work has been very common in our life, heat exchanger has gradually become one of the many industries indispensable mechanical equipment, variety and development in the plate-fin heat exchanger, the belt type heat exchanger, hydraulic oil heat exchanger, and so on. However, some of the heat exchanger in the process of using prone to dirt, especially in petroleum processing this kind of industry, oil pollution is a very common thing on the site.
So, how to reasonably clean mixing of hot oil, dirt?
Nowadays, heat exchanger production is gradually increased, total investment of more and more, which fully shows the demand for heat exchanger is gradually increased. Measure the stand or fall of a heat exchanger operating condition in addition to some fixed equipment characteristics and its production process, how to ensure the neatness of the heat transfer surface, to ensure its good conduction are the important factors of space and the total heat transfer efficiency.
Heat exchanger is above have the dirt to damage from the gross industrial output value is very big, the dirt in the oil dirt is one of the most common and most difficult cleaning dirt, below in the refinery is the easiest scale of atmospheric and vacuum distillation unit and catalytic cracking unit of heat exchanger for cleaning object, the type of dirt are mainly hydrophobic organic compounds membrane oil dirties, is generally used when removing some oil dissolving reaction of some material to clear the oil, petroleum solvents are so common, net halogenated solvents, etc.
Finally, heat exchanger must remember timely cleaning, don't let the oil product time is not yet over the entire heat exchange equipment cleaning, will eventually affect the use of the heat exchanger efficiency.
