Abstract
The invention relates to the field of refined bitumen coking and particularly relates to a coking device for refined bitumen in a laboratory. The coking device comprises a test tube furnace and test tubes and is characterized in that the number of the test tubes are the same as the number of moderate heat reactivity experiments in one set, all test tubes are all in parallel connection with a nitrogen pipeline through a connection pipe, a nitrogen port formed at one end of the nitrogen pipeline is connected with an air source, a spreading port is formed at the other end of the nitrogen pipeline, a drain valve is arranged in a middle and low position of the nitrogen pipeline, the pressure of nitrogen meets the requirements of pressure conditions in experiments, the pressures in all test tubes are uniform, and the elevated temperatures are identical. A tar valve for controlling the number of the experiments is arranged on the connection pipe. Compared with the prior art, the utility model has the benefits as follows: the test tubes to be coked are placed into the matched test tube furnace for coking under uniform pressures, one set of heat reactivity experiments under uniform elevated temperature conditions and uniform pressure conditions requires only 26 hours, and meanwhile, experimental data is enabled to have the advantages of comparability, accuracy in coking condition quantification, and convenient and in-time guidance for production.
Description
Technical field
The present invention relates to refined bitumen coking field, the coking plant of particularly a kind of laboratory refined bitumen.
Background technology
Needle coke is a kind of high-quality carbon material; Gain the name owing to being elongated acicular texture after pulverizing; The needle coke outward appearance has metallic luster, inside has layer structure, and therefore its orientation and conduction, good heat conductivity are to make the primary raw material of steel-making with ultra-high power graphite electrode.The coking principle of needle coke is that pitch is under certain heating condition; Asphaltene molecule is through oligomeric and dehydrogenation polycondensation reaction, and then forms plane macromolecular condensation polymer, becomes spherula through being gathered into karyomorphism; Spherula melts also; Diameter becomes gradually and greatly slowly forms the middle phase of continuity flowable state, at a certain temperature, draws Jiao to make middle solidifying form the green coke (half needle coke) of streamline form through air-flow.
Needle coke production is made up of three unit; Be pretreatment of raw material unit, delayed coking unit, calcining unit; Because PRODUCTION OF PITCH producer is different, because of family's component of refined bitumen is different, its heat reactivity is different; Cause the coking production condition different, make in the big production every tower green coke difference in quality very big.In order to find out the coking condition of component refined bitumen not of the same clan; Must grope the coking condition of different refined bitumens; This groping property experiment can not be carried out big production on the coke drum; In order accurately to quantize the coking condition of pitch, need produce so that in time instruct in the condition of experiment lab simulation coking unit.
Experimental period is long; One time coking heat reactivity experimental period needs 26 hours; Doing one group of heat reactivity experiment needs 10 days, owing to require each heat reactivity experimentation experiment condition unanimity in a group, experiment conclusion just can have comparative; But conditionally completes such as the intensification in experimentation in one group of experiment of the very difficult assurance of coking furnace, constant temperature, pressure are consistent, so experimental result and unsatisfactory.
Summary of the invention
The coking plant that the purpose of this invention is to provide a kind of laboratory refined bitumen; Overcome the deficiency of prior art, can guarantee in one group that the conditionally completes such as intensification, constant temperature, pressure of each heat reactivity experiment are consistent, make the experimental data comparativity strong; Coking condition quantizes accurately, in time instructs and produces.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The coking plant of laboratory refined bitumen comprises test tube stove and test tube, the quantity of test tube with one group in heat reactivity experiment quantity consistent; Each test tube is connected in parallel on the nitrogen pipeline through tube connector respectively, and an end of nitrogen pipeline is provided with nitrogen interface and source of the gas joins, and the other end of nitrogen pipeline is provided with and diffuses mouth; The middle part low level of nitrogen pipeline is provided with tapping valve; Nitrogen pressure satisfies the requirement of pressure condition in the experiment, and pressure is consistent in each test tube, and temperature rise is consistent.
Said tube connector is provided with the tar valve of control experiment number.
Compared with prior art, the invention has the beneficial effects as follows: the coking test tube is put into supporting test tube stove, under unified nitrogen pressure, carries out coking test, can accomplish unified temperature condition; Unified pressure condition according to requirement of experiment, takes out test tube respectively; 10 data can be done for one group,, a test tube arbitrarily can be made for one group according to this thinking; Go out any number certificate, can save time like this, do one group of heat reactivity experiment and only need 26 hours; Make experimental data have more comparativity simultaneously, coking condition quantizes accurately, is convenient in time instruct produce.
