Plate&frame heat exchanger cleaning
The scaling of chemical equipment causes the heat transfer coefficient of the plate heat exchanger and other equipment to decrease. The flow area of the pipe is reduced or the flow resistance is increased, the consumption of energy and materials is increased, and the production efficiency is reduced significantly. At this time, the production efficiency of the production equipment is restored by cleaning and descaling (industrial cleaning|chemical cleaning|boiler cleaning|heat exchanger cleaning).
A buffering agent and an external active agent were added to the formic acid washing solution, and it was found by trial and error. The cleaning effect is better and the corrosion of the cleaning liquid on the plate can be reduced. By chemical test studies on scale samples, formic acid is effective in removing scale. Through the acid immersion test, it was found that formic acid can effectively remove the scale attached to the sheet, and its corrosion effect on the heat exchanger plate is also small. Use hydrochloric acid for cleaning (industrial cleaning | chemical cleaning | boiler cleaning | heat exchanger cleaning) liquid. It is easy to corrode the plate.
