Description
Technical field
The present invention relates to a kind of slurry oil working method, relate in particular to the working method of the slurry oil using in a kind of firing system of prebaked anode oven.
Background technology
The conventional fuel of prebaked anode roasting has heavy oil, coal gas, Sweet natural gas etc.According to oil refining complete processing, heavy oil can be divided into four kinds, atmospheric residue, depressed heavy oil, catalytic heavy and mixing heavy oil.Atmospheric residue refers to the heavy oil that refinery's atmospheric unit fractionates out; Depressed heavy oil refers to the heavy oil that refinery's reliever fractionates out; Catalytic heavy refers to the heavy oil (being commonly called as slurry oil) that plant catalytic, cracking unit fractionate out; Mix the mixing that heavy oil refers generally to depressed heavy oil and catalytic heavy.The advantages such as heavy oil has heat-up rate fast as anode-baking fuel, and combustion period is short, and construction investment is few.But, due to anode-baking firing system equipment precision, therefore oil being required to harshness, the general fuel oil using is 200# heavy oil.Anode-baking furnace is the equipment that energy consumption is high, and firing rate is large, in order to reduce anode-baking cost, is necessary to find the fuel that price is lower and substitutes the 200# heavy oil using at present.
The physical and chemical index of slurry oil and 200# heavy oil approach, but, because catalytic cracking production technique, condensed-nuclei aromatics content higher (> 50%) in slurry oil also contains a certain amount of sulphur, alkali nitrogen and a large amount of catalyst fineses, nonflammable, at present mainly as the blend component of oil fuel or as industrial chemicals.Directly during as industrial heavy fuel oil, there are two problems: 1, slurry oil mechanical impurity is too high with crude slurry oil, easily cause wearing and tearing and the burner hearth coking of equipment, affect firing system steady running; 2, the condensed-nuclei aromatics content of slurry oil is higher, causes oil inhomogeneous, includes full-bodied oil and rolls into a ball, and easily directly causes system jams; Therefore, slurry oil enters burner hearth and air mixed while burning through nozzle atomization, and because its viscosity is large, elaioleucite is large, atomization difficulty, and what can not make that elaioleucite becomes is very tiny, causes and is difficult to perfect combustion, and can produce large quantity of exhaust gas, contaminate environment.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of by reduce viscosity low, reduce elaioleucite, thereby improve the method for combustion efficiency of slurry oil.
In order to address the above problem, the technical solution used in the present invention is:
A method that improves combustion efficiency of slurry oil, comprises the following steps:
(1) heating slurry oil,
(2) use filtration unit to filter for the first time slurry oil,
(3) grind slurry oil,
(4) use filtration unit to filter for the second time slurry oil.
Preferably, in (1) step, slurry oil is heated to 30 DEG C～130 DEG C.
Preferably, in (1) step, slurry oil is heated to 50 DEG C～100 DEG C.
Preferably, in (1) step, slurry oil is heated to 60 DEG C～90 DEG C.
Preferably, in (2), filtering filtration unit used is 1 order～22 order.
Preferably, in (2), filtering filtration unit used is 5 order～15 orders.
Preferably, in (4), filtering filtration unit used is 70 order～110 orders.
Preferably, in (4), filtering filtration unit used is 80 order～100 orders.
Preferably, also comprise and use 101 order～120 object filtration units to filter for the third time slurry oil.
The invention has the beneficial effects as follows: (1) after processing treatment, slurry oil reduced viscosity, granularity diminishes, easily atomization, thus improved the efficiency of combustion of slurry oil; (2) due to low according to above method slurry oil viscosity after treatment, granularity is little, easy atomization, therefore, goes for aluminum anode roasting firing system, has reduced roasting fuel cost; (3) slurry oil burning is more abundant, and efficiency of combustion is improved, and has reduced the discharge of waste gas, is conducive to protection of the environment.
