Abstract
The utility model discloses a preparation device of high-softening-point asphalt. The preparation device comprises a monomer container which is provided with a stirring mechanism and at least three sections of heating areas vertically, wherein each section of heating area is provided with an independent heater; and an inert gas inlet is arranged in the bottom of the monomer container. According to the utility model, the modified asphalt is heated evenly, and the modified asphalt is also evenly heat in the monomer container even if required softening point of the modified asphalt is relatively high. Therefore, all modified asphalt is involved in a polymerization reaction so as to control the softening point within a relatively narrow range, and the quality of products is stable.
Description
Technical field
The utility model relates to the asphalt production technical field, is specifically related to a kind of preparation facilities of high softening point bitumen.
Background technology
At present, modified pitch is by the product that obtains after the coal tar deep processing, and it is the product that coal tar obtains through air distillation, underpressure distillation.Now, along with more and more higher to the requirement of environment, the energy, small-scale steel-making blast furnace is eliminated gradually, and the softening temperature in order to the fire bond of repairing steel-making blast furnace that uses in the market is generally 150 ℃～160 ℃, and carbon content is very low, therefore unstable when temperature is higher, increasing along with the scale of steel-making blast furnace, working temperature is also more and more higher, present fire bond has not reached requirement far away.Pitch then is one of main raw material of preparation fire bond, and its softening temperature plays vital effect to the softening temperature of fire bond.
Especially use the high softening-point special asphalt, can greatly improve the softening temperature of fire bond.The high softening-point special asphalt is the main raw material of preparation fire bond, and it is take modified pitch as raw material, through heat temperature raising, improves the softening temperature of pitch and the content of toluene insolubles.The fire bond of producing like this is used in the steel-making blast furnace and can increases the service life, and has preferably heat shock resistance and chemical erosion ability, thermal conductivity is low and the coefficient of expansion is low.When preparation high softening-point special asphalt, need to carry out heat treated to modified pitch.But when in existing reactor, heating, because modified pitch itself is more sticky, and thermal conductivity is very poor, therefore in reactor during the rising temperature, the temperature of modified pitch itself is difficult to control suitably, thereby cause the inequality of being heated, the high softening-point special asphalt quality of producing is stable not, and namely the softening temperature of product is uncontrollable in a narrower scope.For this reason, at present the average softening temperature of pitch is generally not high yet, and when required softening temperature was high again, pitch will be inhomogeneous owing to being heated, and causes softening temperature uncontrollable in a narrower scope.Therefore need a kind of high softening point bitumen preparation facilities rational in infrastructure of design.
The utility model content
Technical problem to be solved in the utility model provides a kind of preparation facilities of high softening point bitumen, and it can make inner pitch reaction evenly, makes high softening point bitumen, thereby eliminates defective in the above-mentioned background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of preparation facilities of high softening point bitumen comprises monomer container, and described monomer container is provided with stirring mechanism, and described monomer container is setting up and down that at least three sections heating regions are arranged, and described every section heating region is provided with separately independently well heater; The bottom of described monomer container is provided with inert gas entrance.
As a kind of improvement, described monomer container is provided with four sections heating regions, and described every section heating region is provided with separately independently electric heater.
As a kind of further improvement, described each electric heater connects independently temperature regulator.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The device that the utility model provides, be applicable to prepare high softening point bitumen, it is setting up and down at least three sections heating regions, every section heating region is provided with separately independently well heater, therefore can realize at least three sections reacting by heating that modified pitch is arranged above and below in monomer container, just can make modified pitch wherein be heated more even, when even if the required softening temperature of modified pitch is higher, modified pitch also can be heated evenly in monomer container, guarantee that all modified pitches all can participate in polyreaction, thereby softening temperature is controlled in the narrower scope.
The preferred four sections heating regions of the utility model, the softening temperature of modified pitch can be controlled in the narrower scope, namely can avoid modified pitch in monomer container because the inhomogeneous softening temperature that causes that is heated is uncontrollable, simultaneously, four sections electrically heated also are to guarantee that modified pitch reaches under the prerequisite of higher softening temperature, and reduced the reaction times, and it is minimum to consume energy, and comprehensive benefit reaches maximization.
Description of drawings
Accompanying drawing is the utility model structural representation;
Among the figure: 1. monomer container, 2. stirring mechanism, 3. electric heater, 4. inert gas entrance, 5. temperature regulator.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in drawings, the preparation facilities of high softening point bitumen comprises monomer container 1, and described monomer container is provided with stirring mechanism 2, and described monomer container is provided with at least three sections heating regions, and every section heating region setting is well heater independently separately; The bottom of described monomer container is provided with inert gas entrance 4.Because when adopting four sections electrically heated, the softening temperature of modified pitch can be controlled in the narrower scope, namely can avoid modified pitch in monomer container 1 because the inhomogeneous softening temperature that causes that is heated is uncontrollable, simultaneously, four sections electrically heated also are to guarantee that modified pitch reaches under the prerequisite of higher softening temperature, it is minimum to consume energy, comprehensive benefit reaches maximization, therefore the monomer container 1 of following examples employing is provided with four sections heating regions, every section heating region is provided with separately independently electric heater 3, described electric heater 3 is connected with independently temperature regulator 5, realizes separately independent control.But, it will be understood by those skilled in the art that well heater also can adopt three, five etc.
The utility model is not limited to above-mentioned embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done all falls among the protection domain of the present utility model.
