Abstract
The invention relates to a method for treating hydrocarbons-containing organic sludge, in particular to a hydrocarbons-containing organic sludge and cement kiln joint disposal pretreatment method. The method comprises the following steps of: pretreating: analyzing, screening, batching and mixing the hydrocarbons-containing organic sludge; and then recycling: feeding the pretreated hydrocarbons-containing organic sludge in a cement kiln to be recycled. The invention provides a sludge disposal method which has good safety, does not influence the normal production of the cement kiln and is convenient for casting in the kiln simultaneously. The pretreatment method is simple and convenient for operation and wider in application range and is a convenient and feasible method for treating and disposing the hydrocarbons-containing organic sludge in the cement kiln. According to the method for disposing sludge, fuels required by the cement kiln are saved; simultaneously, the production working condition of the cement kiln is satisfied; the secondary pollution of the hydrocarbons-containing organic sludge is avoided; and the purposes of saving energy and protecting environment are achieved.
Description
Technical field
The present invention relates to a kind of treatment process of hydrocarbon-containifirst organic matter sludges.
Background technology
The treatment principle of trade waste is:
1, minimizing.Minimizing is meant quantity and the volume that reduces solid waste by suitable means.Mainly contain two approach: the one, by reform technology, product design or change society consumption structure and refuse mechanism reduce the solid waste generating capacity; The 2nd, as compression, processing such as burning subtract appearance by solid waste disposal.
2, innoxious.The innoxious solid waste that is meant is handled by engineering, reaches and does not damage HUMAN HEALTH, does not pollute the purpose of physical environment on every side.
3, resource utilization.Resource utilization is meant by the whole bag of tricks and reclaims the useful component and the energy that from solid waste purpose is to reduce resource consumption, quickens resources circulation, the protection environment.Comprehensive utilization solid waste can be subjected to good economic benefit and environmental benefit.
The hydrocarbonaceous organic matter sludges belongs to danger wastes, is meant the waste that related industries such as oil, petrochemical industry, boats and ships, coating, oil plant, pigment produce, and generally this type of waste has certain calorific value.Along with above-mentioned industrial development, hydrocarbonaceous organic matter sludges quantity increases day by day.Its general treatment process is a burning method, this method possibility atmosphere pollution, and produced simultaneously burning waste residue also needs land occupation to carry out security landfill, and the land occupation resource is detrimental to health.Still the good pretreatment process of none can carry out the hydrocarbonaceous organic matter sludges regeneration, and this is exist at present one an extremely serious environmental problem.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, under the prerequisite that improves environment, economic benefit, a kind of hydrocarbon-containifirst organic matter sludges and the cement kiln pretreatment process that coexistence is put is provided, method is simple, mud after the processing can regeneration, utilize cement kiln to handle the hydrocarbonaceous organic matter sludges, meet the treatment principle of above-mentioned trade waste.
The technical scheme that the present invention is adopted for achieving the above object is: the pretreatment process that a kind of hydrocarbon-containifirst organic matter sludges and cement kiln coexistence are put, at first carry out pre-treatment: the hydrocarbon-containifirst organic matter sludges is analyzed, sieves, prepared burden and puddles;
And then utilize: hydrocarbon-containifirst organic matter sludges after the pre-treatment is sent in the cement kiln utilized again.
Described pre-treatment: wherein analyze to analyzing the water content of mud; Wherein screening is for sieving the bulk matter of choosing in the mud such as iron block; Wherein batching guarantees to reach cement kiln charging standard for to carry out compatibility according to sludge moisture content with other batchings; Wherein puddle to according to proportion scale mixing stirring, the water ratio of hydrocarbon-containifirst organic matter sludges is that 10% 1 40%(represents with weight percent after pre-treatment).
Described utilization again, pretreated hydrocarbon-containifirst organic matter sludges rotary cement kiln burning method as novel dry is disposed, and incineration temperature is 900-1450 ℃, and residence time of material is 10-40 minute.
Describedly utilize: the hydrocarbon-containifirst organic matter sludges enters cement kiln by kiln tail predecomposition furnace and carries out incineration disposal after the pre-treatment again.
Described hydrocarbon-containifirst organic matter sludges is the waste that related industries such as oil, petrochemical industry, boats and ships, coating, oil plant, pigment produce.The water ratio of described raw material hydrocarbon-containifirst organic matter sludges is that 30% 1 95%(represents with weight percent).
Described batching adopts one or more in spent resin, the trade wastes such as useless dust, unused sandwheel end and waste wood.
Pretreatment process of the present invention is simple, but the present invention provides new method for the harmless treatment of hydrocarbon-containifirst organic matter sludges, can regeneration through the hydrocarbon-containifirst organic matter sludges after this kind treatment process, particularly opened up the regeneration approach that is used to make cement, and utilize cement kiln to handle such mud, hydrocarbon compound in the cement kiln of airtight alkaline environment in the mud can fully burn, and it can not work the mischief to environment.The present invention had both saved the required fuel of cement kiln, had avoided the secondary pollution of hydrocarbon-containifirst organic matter sludges again, thereby had reached the purpose of energy-conserving and environment-protective.Therefore the harmless treatment that utilizes cement kiln to carry out the organic class mud of hydrocarbonaceous can reach the requirement of " innoxious, minimizing, resource utilization " fully.
