Abstract
The present invention discloses a resource treatment method for oil, mud and sand. According to the resource treatment method, oil, mud and sand are conveyed to oil, mud and sand separation complete equipment to separate oil, plastics, sand, fine mud and sewage, wherein the oil and the plastics enter a cracking furnace so as to be subjected to high temperature cracking, the cracked product is adopted as a boiler fuel, the sand is adopted as a subgrade material, the fine mud is adopted as a mixing material for producing briquette, and the sewage is reused or enters an oil extraction sewage treatment plant so as to be treated. According to the invention, the complete separation effect of oil, mud, sand and water is achieved so as to easily achieve resource utilization on oil, mud and sand; and the physical method is adopted to separate so as to substantially reduce the treatment cost.
Description
Technical field
The invention belongs to the process field of solid waste, be specifically related to the recycling processing method of oil sludge and sand.
Background technology
Oil sludge and sand refers to and produces in field produces activity, is mainly derived from oil extraction, collects the links such as defeated and refining, by the mixture of the mud of crude oil and other Organic Pollution, sand, water.The hydrocarbons contained due to oil sludge and sand is larger to environmental hazard, is put into the hazardous waste (HW08 item) in " national Hazardous Waste List ".National each elephant has a large amount of oil sludge and sand to produce every year in process of production now.Being a large amount of exhaust emission environment of oil sludge and sand on the one hand, is that national environmental protection department starts the charges for disposing pollutants to oil sludge and sand discharge collection great number on the other hand.So no matter consider or consider from the economic interests of enterprise from environmental protection, the improvement of oil sludge and sand has all become the task of top priority, the key of dealing with problems is to find a kind of environmental friendliness and cost-effective processing method.
Oil sludge and sand is the thick material of a kind of brownish black of component complexity, is mainly made up of water, silt and mineral oil three parts, and water, oil and silt present a kind of highly stable suspension emulsified state.Oil sludge and sand solid concentration is low, and moisture content is high, presents suspended dispersed state, thereby bulky.The different oil sludge and sand of originating, as fresh and aging oil sludge and sand, its composition and physical property all may have bigger difference, as viscosity, moisture content, dehydration property, oil-water separativeness etc.
Conventional three-phase (oil, water, mud) separating treatment technology path has following several at present: (1) oil sludge and sand-heating homogenize-chemical demulsification-separation-mechanical dehydration of heating-mummification landfill; (2) oil sludge and sand-heating homogenize-Chemical Decomposition-mechanical dehydration-solidifying-microbiological treatment; (3) oil sludge and sand-heating homogenize-solvent extraction-oil separates.Chemical demulsification or Chemical Decomposition are by adding coagulant, flocculant or demulsifier to realize in oil sludge and sand.This class treatment technology not only will mix certain proportion water in oil sludge and sand, has increased the treating capacity of oil sludge and sand; And need to add a large amount of inorganic coagulants or organic polymer coargulator or demulsifier, increase processing cost.Adopting the methods such as solvent extraction to process oil sludge and sand is object mainly with simple recovery mineral oil, does not consider effective utilization of oil sludge and sand integrated treatment and other components.
Therefore, develop and a kind ofly oil sludge and sand is realized to method innoxious, recycling treatment there is important economy and social effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of recycling processing method of oil sludge and sand.
A recycling processing method for oil sludge and sand, comprises the steps: that oil sludge and sand is delivered to oil sludge and sand is separated into complete equipment, separates fuel-displaced, plastics, sand, thin mud, sewage; Described oil, plastics enter Pintsch process in pyrolysis furnace, and pyrolysis product is as boiler oil; Described sand is as roadbed material; Described thin mud is as the mix of producing moulded coal; Described sewage carries out reuse or enters oil extraction-generated waste water treatment plant processing.The cracking temperature of described oil, plastics is 400～450 ℃.The oil content of described sand is lower than 3%.
Oil sludge and sand is separated into complete equipment and is made up of agitator, high-pressure pump, heater, oil trap, sand scraper, water pump, settling tank; Heater and high-pressure pump generating high-pressure hot water; Oil sludge and sand in agitator is broken rapidly at high-pressure water heating with under stirring; On oil, warp float oil trap is collected; Sand sinks to falling into sand scraper through sieve aperture; Plastics are separated by mixing arm; Inputted in settling tank by water pump containing thin dirt water.The hot water temperature that described heater provides is 80 ℃～90 ℃.Described containing thin dirt water sedimentation time in settling tank be 3～5 hours.
The invention provides a kind of recycling processing method of oil sludge and sand, its remarkable advantage is: (1) has reached the thorough separating effect of oil, mud, sand, water, has realized the recycling of oil, mud, sand, and pollutant emission is zero; (2) physical methods such as combination screening, stirring, washing, sedimentation, compared with traditional handicraft, have stopped the use of chemical agent, greatly reduce processing cost; (3) equipment one-time investment expense is low, and operation management expense is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Hydro-thermal to 90 ℃ is started to agitator with moulded coal, selection rate setting is 10r/min.Then start roots blower, set the 4 cubic metres of compressed air that send per minute, with 0.5kg/cm
2pressure sprays from two bottom sides pore, and hot water is washed away at a high speed in agitator tank, adopts gravity system that oil sludge and sand is inputted to agitator tank, and transfer rate is 5 tons/hour.Broken rapidly under the conditions of making a concerted effort such as oil sludge and sand is washed away at high pressure, stirring, hot water, the density of oil is little, floats to rapidly whip topping, from oil trap, flows out and collects.The sandstone proportion of greater particle size is larger, sinks to spilling from sieve aperture rapidly, continues to use hot water back flush in dropping process, and the sand of rinsing well adopts sand scraper to collect, and delivers to construction site and uses as building materials.The foreign material such as plastics, faggot a small amount of in oil sludge and sand are taken out of agitator tank and are collected by mixing arm sorting.In agitator tank middle and high concentration sewage, contain a large amount of thin mud, pumping sewage is to settling tank, and after sedimentation in 4～5 hours, the sewage on top can be delivered in heater and continue to use, or is delivered to sewage treatment plant's processing; The thin mud of bottom sedimentation takes out for moulded coal raw material.
In order to save the sedimentation time, can mud scraper be set in settling tank bottom, on centre rotational axis, scrape very lentamente, be 2～20cm/S as set rotary speed.Cause hole owing to forming little eddy current, the Interstitial Water of mud granule and bubble are overflowed, concentrated effect can improve 20%, and concentration time can shorten 3～4 hours.
