' H', > is the current thermal oil furnace cleaning and descaling process The best product for professional carbon removal for oil furnace cleaning pipes. The appropriate thermal oil furnace cleaning agent should be selected according to the usage conditions of the company's own thermal oil furnace. Otherwise, not only will the purpose of cleaning not be achieved, but the normal operation of later production will be affected. Here are several methods for you.
< ' H', ' H', >. Alkaline water-based cleaning agent has a good effect on oily medium-temperature coke deposits. However, after treatment, there is still a dense graphitized high-temperature coke layer remaining on the inner wall of the specimen, so it must be It is removed after further pickling to prevent the residual carbon layer from affecting the quality and heat transfer effect of the thermal oil. The two-step cleaning process of alkali washing and pickling is used for carbon deposits in heat medium furnaces and pipes. It has the advantages of high cleaning rate, low cleaning temperature, non-toxicity and low cleaning cost.
< ' H', ' H', >. Since coke scale is a complex mixed dirt mainly composed of organic matter, its adhesion to the metal surface is mainly the physical adsorption of van der Waals force, and the dissolution and washing method is used. , dissolve the tar in the organic solvent and remove it naturally as the organic matter dissolves. The cleaning ability of this cleaning agent is quite strong and is not greatly affected by temperature.
< ' H', ' H', >. The additives use the similar miscibility principle to elute or degrade tar scale and prevent the deterioration of thermal oil. This method can be used for cleaning without stopping the machine. The additives can withstand high temperatures above ℃ and dissolve in the thermal oil without affecting the chemical properties of the thermal oil.
< ' H', ' H', >. Composite cleaning agents are mainly composed of several surfactants under the synergistic effect of detergent builders. They first adsorb on the surface of grease to make it wet and expand, and then the cleaning agent penetrates into The oil and dirt gaps gradually curl into micelles under the action of the compound cleaning agent and are continuously emulsified. The continuous circulation of the pump can make the dispersed and emulsified oil and dirt separate from the heat transfer surface.
< ' H', ' H', >. Additives can capture the coke-generating groups of aromatic hydrocarbons and hydrocarbon chain dehydrogenation cracking and condensation reactions, and inhibit the deterioration and coking of heat transfer oil. In addition, certain components in the additives clean and disperse the heavy components of coked and condensed aromatic hydrocarbons after dehydrogenation in the system, causing them to liquefy and peel off from the metal surface.
