How to clean an electric heat conduction oil furnace

During use, hot oil will coke and accumulate carbon, which can form an insulation layer and reduce heat exchange efficiency. Professor Guangzhi of Yancheng City, how to add alkali, organic solvent, surfactant, complexing agent, oxidant, corrosion inhibitor, adsorbent, anti sedimentation agent and other additives, and clean the system by heating and mechanical scrubbing. Decoking is achieved through methods such as dissolution, wetting, adsorption, emulsification, and dispersion.
The electric heating heat transfer oil furnace undergoes two steps of alkali washing and acid washing: discharging the heat transfer oil → steam blowing the stagnant oil → alkali washing agent → water washing → acid washing → passivation → completion. Mechanism: Alkaline water-based cleaning agents have good treatment effects on oily medium temperature carbon deposits, but after treatment, there is still a dense graphitized high-temperature carbon deposit layer on the inner wall of the sample, which needs to be further removed by acid washing to prevent the residual carbon layer from affecting the quality and heat transfer effect of the heat transfer oil. The use of alkali washing and acid washing for pipeline carbon deposition has the advantages of high cleaning rate, low cleaning temperature, and low cost.
The organic elution process of the thermal conductivity oil heating device: adding additives to the running thermal conductivity oil can peel off carbon deposits, and then remove oil residue through clarification and filtration. Principle: The present invention adopts a similar mixing principle to wash off coking oil scale or degrade coking oil scale to prevent its deterioration. This method can be continuously cleaned. It can dissolve in heat transfer oil at high temperatures above 260 ℃ without affecting its physical properties, and the dosage can exceed 5% of the heat transfer oil. In application, the heat transfer oil heater and pipeline do not require cooling and do not affect production.
Dissolution cleaning process: discharge of heat transfer oil → steam blowing of retained oil → organic solvent cleaning solution → passivation solution. Coke scale is a complex mixture mainly composed of organic matter, and its adhesion to metal surfaces is mainly through physical adsorption. The Yancheng Guangzhi thermal oil furnace adopts a solubility washing method to dissolve tar in organic solvents and naturally remove it as organic matter dissolves. This type of cleaning agent has a good cleaning effect.
The comprehensive cleaning process for the heat transfer oil heater: discharge of heat transfer oil → steam blowing of stagnant oil → circulating cleaning with cleaning solution. Mechanism: Compound cleaning agents are mainly composed of various surfactants that adsorb onto the oily surface under the synergistic effect of cleaning aids, causing it to wet and expand. Then, the cleaning agent is infiltrated into the oil tank, gradually rolling up the oil, and continuously emulsifying under the action of the composite cleaning agent. By using a continuous circulation cleaning pump, dispersed emulsified oil can be separated from the heat transfer surface. It can effectively crush and disperse carbon deposits, as well as effectively dissolve organic hydrocarbons. The process flow is simple, and the heat transfer oil heater is basically corrosion-free, but it must be cleaned when parking.
