What are the general reasons for heat exchanger cleaning? The reason of cleaning the heat exchanger cleaning the reason of the cleaning of the heat exchanger is that in the production process of the chemical industry  due to many reasons  the heat exchanger equipment and the pipeline line will produce many dirt such as coking, oil dirt, scale, scale, sediment, corrosion products, polymer, etc. These fouling will make the equipment and pipeline fail. The production of the system will be reduced; the energy consumption and material consumption will increase. When the dirt corrosion is especially serious, the process will be interrupted. The equipment system will be forced to stop production. All kinds of economic losses will be caused directly. Even the malignant production accidents may occur. In the scientific development, it is almost impossible to avoid the generation of dirt completely. Therefore, the cleaning of heat exchanger and other equipment becomes an indispensable link in industrial production, especially in petrochemical and thermal power plant production. The development of heat exchanger cleaning is influenced by the traditional thinking concept and the lack of cleaning technology resources. Most enterprises and individuals have influence on the fouling of heat exchanger and the removal process still stays in the traditional "destructive" process and concept of mechanical, high pressure water and chemical pickling; And simply think that the equipment cleaning only in the case of serious impact on production will consider the formation of its unknown scale in the continuous impact on the energy consumption of enterprises  engulf the profits of the enterprise. Moreover, in order to reduce the cost of cleaning, the cleaning method which damages and corrodes the equipment is selected. The equipment scrap and production stagnation are caused. The cost is hundreds times higher than the cleaning agent, even thousands times higher than that of the cleaning agent. For example, a cement group uses oxalic acid to clean heat exchanger. The cleaning time is not more than 2 hours. Because the cleaning is not thorough, the cleaning time has changed from one year to three times a year. The two times of shutdown and shutdown time have been increased. The indirect loss to the enterprise has been caused. At present, all countries are developing environmental cleaning technology to reduce energy consumption and stop the excessive damage to the environment.
