Abstract
The invention discloses an allocating technique of fuel oil, which comprises the following steps: selecting coal tar through 10-order, 20-order, 40-order, 60-order and 80-order multi-grade filter to remove gel, tar and ash; inputting the raw material into oil water separating tank; heating to 70 deg. c; separating oil from water; transmitting the dehydrating raw material into reserving tank to blend with certain proportion of combustion adjuvant; filtering through 80-order to obtain the product.
Description
Technical field:
The present invention relates to the allocating technology of oil fuel, especially a kind of blending technology of coal-tar fuel.
Background technology:
At present, coal tar is being that advantage substitutes and to be mixed crude oil applications in injection boiler with cheap price just, but its effect is general, mainly has following problem: the one, and the coal tar ash content is bigger, and the boiler soot-blowing number of times is more relatively.The 2nd, coal tar smell when low temperature is little, but temperature is when reaching 60 ℃, and volatile quantity increases, and smell is bigger.The 3rd, because the viscosity height, coal tar can only use more than 60 ℃, uses like this to be restricted, and has increased cost simultaneously.
The Liaohe Oil Field utilizes coal-tar fuel to be applied to this technology of heat-collecting steam boiler at present, after having done a large amount of experiments, determined the modulator approach of coal tar, at first, the main source of ash content when thinking the coal-tar fuel burning, mechanical impurity in coal tar mainly contains following material and constitutes: formations such as some solid particulates of sneaking in coal dust, tar acid, tar bases and the course of processing in the impurity.Wherein other solid particulates of sneaking in the coal dust and the course of processing can be removed fully by cascade filtration, and the removal of tar acid, tar bases, can remove by adding chemical agent reaction back generation precipitation, also can directly select the base oil that does not contain tar acid or tar bases for use in addition.By adding the ignition dope of light constituent, well to regulate the coal tar oil viscosity, thereby reached 40 ℃ of incendivities, the state of transportation has been saved heating cost, and the volatilization of smell has simultaneously also obtained effective control.
Summary of the invention:
The object of the invention is in order to overcome above-mentioned shortcoming, and a kind of blending technology of coal-tar fuel that provides, modulated coal-tar fuel has overcome because of the coal tar ash content is big, and smell is big, have a strong impact on coal-tar fuel oil and be applied to the gas injection boiler and send out drawback, widened the coal-tar fuel range of application.
Technical scheme:
For reaching above-mentioned target, the present invention adopts following steps to finish; Getting coal tar raw material filters and removes colloid through 10 orders, 20 orders, 40 orders, 60 orders, the multistage selected formula strainer of 80 orders, in bituminous matter and the ash impurities input gun barrel, be heated to and carry out oily water separation more than 70 ℃, then dehydrated raw material oil is sent in the storage tank with after a certain proportion of ignition dope mixes, again after 80 order strainers filter product.
Described ignition dope is the heavy oil of content 10-30%, and its addition is 0.5-10%.
The present invention compared with prior art has distinguishing feature:
After coal tar fuel was allocated processing, before being better than allocating, ash content, calorific value, smell all had obvious variation.
(1) principal element that influences the coal-tar fuel burning quality has ash content, its source is the mechanical impurity in the coal tar, mainly containing following materials constitutes: the formations such as some other solid particulate of sneaking in coal dust, tar acid, tar bases and the course of processing, the present invention removes by the cascade filtration method, thereby has reached the standard of on-the-spot use.
(2) generally about 8800 kilocalories, after adding ignition dope, calorific value increases to more than 8900 kilocalories preceding calorific value of allotment, and combustion efficacy is more abundant, and thermo-efficiency is higher.
(3) smell is little during coal-tar fuel low temperature, but that temperature reaches 60 ℃ of volatile quantities is bigger, the peculiar smell height, so the removal of peculiar smell hides agent and reduces use temperature by adding, and removes peculiar smell thereby reduce volatilization.
In addition, after this coal tar had burnt, pollution-free, unit consumption was low, the thermo-efficiency height, and chemical transformation does not take place in long-term placement, can be used for uphole steam generator, and during use, not needing heating is incendivity, does not stop up nozzles during burning, and the low temperature volatile matter is few, and loss is few.
Embodiment:
The present invention is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Embodiment 1:
Main raw material coal tar in this invention is middle temperature oil fuel, oil viscosity is little, the calorific value height, ash content is low, moisture few the use do not have corrosion to equipment, raw material needs through 10 orders during auxiliary tone, 20 orders, 40 orders, 60 orders, the multistage selected formula strainer of 80 orders filters, can remove colloid wherein, bituminous matter and ash impurities, solved the problem of stopping up nozzles in the use, during allotment, in the input gun barrel, be heated to more than 70 ℃, can make oil in the raw material, water is accelerated to separate, and through dehydrated raw material oil, is transported to and carries out the technology allotment in the storage tank, adding content earlier is 10-30% addition 0.5-10% heavy oil, ignition dope (heavy oil) and the industrial essence of hiding agent of thousandth to ten thousand/five will add liquid then and raw material stirring is even, be product after filtering in the warp let-off 80 purpose strainers after mixing.
Embodiment 2:
An amount of ignition dope that is added during preparation among the present invention and industrial essence have played as decoking agent and dispersion agent and have improved the effect of oil product flowing property and in use reduce viscosity, improve calorific value, reduce and pollute, smolder when having solved burning, stupid, the naphthalene in dust stratification and the high temperature tar, methylbenzene high volatility, the peculiar smell hang-up, the stock oil of being allocated filters through 10 orders, 20 orders, 40 orders, 60 orders, the multistage selected formula strainer of 80 orders in addition, after adding ignition dope, can remove coal dust, tar acid, tar bases and can reduce living load again, thoroughly removal of contamination.Incendivity during 40 ℃ of this coal tar combustion oils.
Claims (2)
1, a kind of blending technology of coal-tar fuel is characterized in that: described allocating technology adopts following steps to finish; Getting coal tar raw material filters through 10 orders, 20 orders, 40 orders, 60 orders, the multistage selected formula strainer of 80 orders, remove wherein colloid, bituminous matter and ash impurities composition are input in the gun barrel, be heated to and carry out oily water separation more than 70 ℃, then dehydrated raw material oil is sent in the storage tank with after a certain proportion of ignition dope mixes, again after 80 order strainers filter product.
2, a kind of blending technology of coal-tar fuel according to claim 1 is characterized in that: described ignition dope is the heavy oil of content 10-30%, and its addition that joins in the coal-tar fuel is 0.5-10%.
