Description
Technical field
The present invention relates to liquid carbon-containing fuel, specifically is oil fuel and the working method thereof that substitutes heavy gas oil with the heavy oil modification about a kind of.
Background technology
Heavy oil is that remaining residual oil makes after going out gasoline, kerosene and diesel oil by the cracked residue oil of oil and petroleum fractionating.Be characterized in that viscosity is big, can only be used for boiler, industrial furnace etc. usually and make fuel usefulness.Atomizing for the kinematic viscosity of improving heavy oil during with burning, in concrete the application, heavy oil is before getting into burner; Must heat with high-pressure water vapor in advance, but the high-pressure water vapor heating installation is huge, enterprise investment is big; And, be prone to cause environmental pollution because heavy oil combustion is incomplete.At present some medium and small sized enterprises adopt the heavy gas oil oil that acts as a fuel to be used for boiler or industrial furnace, but because of in recent years, the oil price of China is influenced by the world market oil price rise, and this has directly influenced the production cost of medium-sized and small enterprises.And contemporary petroleum industry faces oil product and becomes heavy, and carbon residue is too high, problems such as petroleum resources exhaustion; After some crude oil fractionated out gasoline, kerosene and diesel oil, the quality of remaining BO was extremely low, the burning difficulty; Even can't fire burns, these inferior quality heavy oil are deposited in the warehouse for a long time.In order to fully utilize these natural resourcess, find a way out for these inferior quality heavy oil, research purpose of the present invention is to heavy oil, and especially inferior quality heavy oil carries out modification, and making it becomes the oil fuel that substitutes heavy gas oil, to satisfy the needs of market oil fuel.
Summary of the invention
The present invention provides a kind of oil fuel and working method thereof that substitutes heavy gas oil with the heavy oil modification.
A kind of oil fuel with the alternative heavy gas oil of heavy oil modification is by heavy oil, diesel oil, and emulsifying agent contains benzene compound, and the printing and dyeing mill's trade effluent and the phosphoric acid that contain aniline are formed.It is a kind of good flowability that has, ignition quality and sprayability, and have high heating value, low ash content, low sulphur content, low mechanical impurity, non-corrosive fresh fuel oil.
The present invention is following with the component and the weight % content of the oil fuel of the alternative heavy gas oil of heavy oil modification:
Composition weight % content
Heavy oil 70-85
Diesel oil 2-8
Emulsifying agent 1-3
Contain benzene compound 1-5
The trade effluent 5-15 of printing and dyeing mill that contains aniline
Phosphatase 11-5
The present invention is a heavy oil with the raw oil that the heavy oil modification substitutes the oil fuel of heavy gas oil, can be brand heavy oil, for example No. 20; No. 60, No. 100, No. 200; Also can be low reduced fuel oil, residual oil for example, #180 heavy oil; #250 heavy oil, other BO of the 350-540 of #280 heavy oil or petroleum tar ℃ cut.Another raw oil is diesel oil, comprises heavy gas oil or solar oil.
Become the physical condition of water-in-oil-type for the oil fuel product that makes the heavy oil modification; The present invention selects the emulsifier prodn of HLB value (hydrophile-lipophile balance value)＜6 for use, the S60 that produces of the first chemical plant of Jiangyin City China for example, S65; S80 or S85, their HLB value is between 1.5-5.9.
The said benzene compound that contains is to be selected from benzene, toluene or YLENE, and containing benzene compound all has been the effect of ignition dope with the printing and dyeing mill's trade effluent that contains aniline, go out in addition mould and bacteriological action.
Said phosphoric acid is used to regulate the pH value and is 7-9, and is also favourable to desulfurization, and can improve the storage stability and the combustionproperty of oil fuel product.
The present invention is with the working method of the alternative heavy gas oil oil fuel of heavy oil modification, and the process flow sheet of working method is referring to Fig. 1.
With heavy oil, diesel oil, emulsifying agent, contain benzene compound, the printing and dyeing mill's trade effluent and the phosphoric acid that contain aniline is reinforced by the proportioning of above-mentioned prescription, order is carried out circulate repeatedly spray mixing emulsification and filtration of four steps in four placed in-line spray mixing emulsors.The first step; (" the spray mixing emulsor is applied for " utility model " patent ") is through spray mixing emulsification 0.5-2 hour that circulates repeatedly in the batching adding spray mixing emulsor 1; Mixed solution material temperature of reaction rises to 50-70 ℃, and the mixed solution material is emitted, and filters through the 180-320 order; In second step, the first step gained filtrating gets into spray mixing emulsor 2, and operation is with spray mixing emulsor 1; The mixed solution material of emitting filters through M28-M14; In the 3rd step, the second step gained filtrating gets into spray mixing emulsor 3 again and operates equally, and the mixed solution material of emitting filters through M10-M5; In the 4th step, the 3rd step gained filtrating gets into spray mixing emulsor 4 again, same operation, and the mixed solution material of emitting filters through M10-M5, promptly gets the oil fuel product that the heavy oil modification substitutes heavy gas oil.
The structure of said spray mixing emulsor is seen Fig. 2-Fig. 4, mainly comprises mixing kettle 3, charging stock tank 6, spraying plant 5, residual oil pump 1, hot resistance temperature measuring head 2, three-way valve 7 and drainage conduit 4.The filling tube 9 of said charging stock tank 6 bottoms be installed in mixing kettle 3 on cover, and stretch in the mixing kettle 3.Said spraying plant 5 comprises spray channel 19 and shoe 15.Spray channel 19 comprises the nozzle entrance 10 that communicates successively, turbulent flow road 11, hybrid chamber 12 and jet exit 13.Nozzle entrance 10 is doline, and the diameter in turbulent flow road 11 is 1.2-3mm, and two sides of hybrid chamber 12 walls respectively are provided with a flow and lead mouth 14.Shoe 15 is vertically to being arranged on the spray channel 19, and flow lead mouthfuls 14 and jet exit 13 between, be covered with aperture 16 on the shoe 15, the aperture of aperture 16 is 1-3mm, the percentage of open area on the shoe 15 is 60-80%.Also a filtering net 20 can be set below mixing kettle 3.Said residual oil pump places on the connecting tube 8 between three-way valve 7 and the mixing kettle 3 bottom discharge mouths 18, and drainage conduit 4 links to each other with three-way valve 7.Said hot resistance temperature measuring head 2 is fixedly set in the mixing kettle 3, and the loam cake that passes mixing kettle 3 through lead links to each other with temperature indicator 17.
The present invention is the shinny oil in water emulsion of a kind of Dark grey with the oil fuel that the heavy oil modification substitutes heavy gas oil, and its combustion heat value can reach 9000-12000KCal/kg, is a kind of good flowability that has; Ignition quality and sprayability, and have high heating value, low ash content; Low sulphur content, low mechanical impurity, non-corrosive oil fuel; Can be used for oil-firing boiler, industrial furnace and in, slow speed diesel engine.The present invention lists in table 1 with the oil fuel performance of products parameter that the heavy oil modification substitutes heavy gas oil.
