Abstract
The invention relates to a heat-transfer-oil strong cleaning agent, and concretely relates to a heat-transfer-oil organic strong cleaning agent and a usage method saving the same. The heat-transfer-oil organic strong cleaning agent composition is prepared by selecting an organic solvent, a surfactant, an oxidant, a corrosion inhibitor, an adsorbent, a stabilizer and a compolexing agent according a specific ratio, successively adding into a material mixing tank and uniformly mixing the above raw materials. When being used, the organic cleaning agent composition is capable of relatively completely dissolving oil dirt and carbon deposit. Compared with a conventional method which causes waste because of large circulating usage amount of the cleaning agent composition, a disclosed usage method is capable of reaching the same effect under the premise of using a less amount of the cleaning agent.
Description
Technical field
The present invention relates to a kind of clean-out system, particularly, relate to the using method of the organic strong detergent of a kind of thermal oil and saving clean-out system.
Background technology
Thermal oil is a kind of organic heat-carrying agent, as medium liquid phase circulation in heat-exchange equipment system, reaches the object of transferring heat.The industries such as wood-based plate, petrochemical complex, weaving, chemical fibre, printing and dyeing, light industry, Crude Oil Transportation, food, highway engineering, building materials are widely used at present.Have good thermal conduction, thermo-efficiency is high, and thermal capacity is large, the advantages such as running maintenance cost is low.But thermal oil is easily oxidized in heat-processed, thermo-cracking, thermal polycondensation reaction at high temperature occur, and thermal polycondensation reaction can cause generating macromolecule product, forms colloid.Thus colloid is attached to boiler tube inwall, just easily forms coking, further, when service temperature exceedes its design temperature, often also cause autocatalysis thermolysis, cause managing interior coking.Process stream leaks brings heat-conducting oil system into, form corrosion product and generate iron rust, and the contaminating impurity brought in overhaul all can impel inside pipe wall generation coking.Therefore heat conduction grease comprises wax, Jiao Zhi, pitch, carbide, charcoal divide, ferric oxide, organic polymer and catalyzer etc.
Coking can cause furnace tube heat transfer decrease in efficiency, and boiler tube internal-external temperature difference is large, when outside wall temperature reaches 600-700 DEG C, easily burns boiler tube, thus causes accident.Therefore, coking becomes the greatest problem that hot oil furnace faces, and solution normally carries out cleaning and descaling.
Clean-out system conventional at present comprises: the kinds such as basic solution, organic solvent and surfactant soln, basic solution refers to the alkaline cleaner comprising the alkaline substance such as sodium hydroxide, sodium carbonate composition, this clean-out system is to better to vegetable and animals oils cleaning performance, but poor to mineral oil cleansing power, and the use of highly basic easily makes mechanical part sustain damage; Conventional petroleum solvents, halogenated hydrocarbon solvent have stronger solubilizing reaction to oils, and with clear heavy oil stain, tar dirt and coke dirt, but lower boiling petroleum solvents is all inflammable, and application is restricted; Surfactant soln is owing to having amphiphilic structure, and thus its aqueous solution has the effect such as emulsion dispersion and solubilising, has good Scavenging activity for liquid grease, but poor for solid-state grease removal ability.
In addition, general thermal oil equipment washing, no matter organic or inorganic cleaning, all must fill heat-conducting oil system by liquid, ON cycle pump, dissolves the coking in pipeline and equipment, waste very much with a large amount of clean-out systems.
The invention provides the organic strong detergent composition of a kind of thermal oil, this additive can remove grease, or make grease degraded prevent thermal oil from going bad, and the organic strong detergent composition of thermal oil of the present invention, can clean when not stopping, consumption is few, and efficiency is high, along with the operation of thermal oil, gradually grease got rid of or eliminate.
