Abstract
The invention provides an industrial cleaning agent which consists of 0.1-5wt% of polysaccharide colloid dispersing agent or triglycerin-3-diisostearate/dimer glyceride copolymer dispersing agent, 0.01-5wt% of iron ion complexing agent, 0.01-5wt% of manganese-containing composite oxidant, 0.01-3wt% of passivating agent, 0.01-5wt% of water softener and 95-99.8wt% of water. The industrial cleaning agent has the advantages of simple preparation method, high efficiency, cleanness, improvement of the safety of maintenance operation and improvement of the maintenance operation environment.
Description
Technical Field
The invention belongs to the field of industrial cleaning agents, and particularly relates to a cleaning agent for overhauling and cleaning an oil refining chemical device.
Background
In recent years, the requirements of the national on the safety and environmental protection of the maintenance operation of chemical equipment are increasingly increased. For example, in the oil refining device, not only is the cleaning and high efficiency requirements required in the cleaning process of the equipment met, but also the ferrous sulfide cannot be remained after the equipment is opened, so that the spontaneous combustion accident is prevented. Meanwhile, the odor escape of malodor needs to be avoided, and the environmental odor of operation construction is ensured to be effectively controlled. When overhauling, the requirements of safety and environmental protection are firmly met, and safety production accidents in overhauling operation are avoided. When a general chemical device is cleaned, long-chain organic fatty acid salt is used as an emulsifying agent and a penetrating agent, and the components are added to facilitate the cleaning of equipment, but the long-chain organic fatty acid salt is dissolved in the waste water after the equipment is cleaned, so that the COD in the waste water is obviously improved. When the COD of the chemical cleaning wastewater of the oil refining device exceeds 1000mg/L, the chemical cleaning wastewater is not suitable to directly enter a biochemical wastewater treatment system, which clearly brings challenges to the post-treatment of the wastewater.
Disclosure of Invention
The invention aims to provide an industrial cleaning agent aiming at the defects of the prior art.
The technical scheme of the invention is as follows:
An industrial cleaning agent consists of 0.1-5wt% of polysaccharide colloid dispersing agent or triglycerin-3-diisostearate/dimer glyceride copolymer dispersing agent, 0.01-5wt% of iron ion complexing agent, 0.01-5wt% of manganese-containing composite oxidant, 0.01-3wt% of passivating agent, 0.01-5wt% of water softener and 95-99.8wt% of water. The metal salt selected by the passivating agent can be combined with sulfur anions to generate sulfides with a solubility product lower than that of ferrous sulfide, such as zinc salt, zinc sulfate, zinc acetate, zinc nitrate, zinc chloride, zinc gluconate and the like, so that the ferrous ions and the sulfur anions are prevented from being combined to generate the ferrous sulfide to achieve the deodorizing effect. The manganese-containing composite oxidant is combined to oxidize negative bivalent sulfur into higher valence state, so that malodorous smell in the oil refining device is effectively removed, and the overhaul operation environment is improved. The water softener is used for forming a complex with calcium and magnesium ions to play a role in scale prevention, and common water softeners include phosphate, hydrogen phosphate, dihydrogen phosphate, disodium ethylenediamine tetraacetate and the like. The iron ion complexing agent has the function of complexing with iron ions to prevent the formation of iron compound precipitation in alkaline environment, and common iron ion complexing agents include citrate, gluconate, sorbate and the like. According to the invention, the polysaccharide colloid dispersing agent or the triglycerol-3-diisostearate/dimer glyceride copolymer dispersing agent enables a cleaning agent system to form colloid, so that the composite oxidant is more uniformly dispersed, the oxidation effect is better, a new COD source is not introduced, and the cleaning wastewater is beneficial to directly enter a biochemical sewage treatment system for treatment.
As a further improvement of the technical scheme, the manganese-containing composite oxidant accounts for 0.01 to 3 weight percent for balancing the oxidation effect and the cost. The manganese oxidant is one or a mixture of more of potassium permanganate, potassium manganate, manganese sulfate, manganese nitrate and manganese acetate.
As a further improvement of the technical scheme, in order to enhance the S 2- oxidation effect, the manganese-containing composite oxidant consists of a manganese oxidant and an iron oxidant, wherein the content of the iron oxidant is 0.01-1wt% based on the mass of the cleaning agent, and the iron oxidant is one or a mixture of more of ferric sulfate, ferric chloride and ferric nitrate.
As a further improvement of the technical scheme, the passivating agent content is 0.01-1wt% in order to balance the passivating effect and the cost.
