Abstract
The invention relates to a system and a method for rapidly melting asphalt. The system comprises a rapid asphalt melter with a stirrer, an asphalt delivery pump arranged between a bottom asphalt outlet and an asphalt inlet of the rapid asphalt melter, a filter arranged between the bottom asphalt outlet and asphalt delivery pump, a first pneumatic asphalt valve arranged between the bottom asphalt outlet and filter, a second pneumatic asphalt valve arranged between the filter and asphalt delivery pump, and a third pneumatic asphalt valve arranged between asphalt delivery pump and asphalt inlet. The inventive system has advantages of rapid asphalt melting speed of a buried pump rapid asphalt melter, and low failure rate of a stirring type rapid asphalt melter.
Description
Technical field
The present invention relates to a kind of asphalt melting system and method, relate in particular to the system and method for a kind of pitch rapid melting of charcoal element, chemical industry.
Background technology
Pitch rapid melting technique generally adopts the tube bundle heater pitch rapid melting device with buried pump at present, or employing is with the tube bundle heater pitch rapid melting device of agitating vane, tube bundle heater pitch rapid melting device with buried pump, burn-off rate is fast, but because pitch contains impurity, buried pump easily breaks down, and buried pump is placed in in the cell body that is incubated heating agent, the maintenance difficulty.With the tube bundle heater pitch rapid melting device failure rate is low of agitating vane, but the rotating speed of agitating vane is slower, and the speed of asphalt melting is slow.
Summary of the invention
In order to address the above problem the system and method that the invention provides a kind of pitch rapid melting, its objective is in order to solve buried pump pitch rapid melting device overhaul of the equipments difficulty, the low problem of stirring type asphalt rapid melting device melting efficiency.
For reaching the system of a kind of pitch rapid melting of above-mentioned purpose the present invention, comprise the pitch rapid melting device that band stirs, being provided with the asphalt delivery pump between the bottom pitch outlet of the pitch rapid melting device that band stirs and the pitch import is connected, between the outlet of bottom pitch and asphalt delivery pump, be provided with strainer, be provided with the first pneumatic asphalt valve between bottom pitch outlet and the strainer, be provided with the second pneumatic asphalt valve between strainer and the asphalt delivery pump, be provided with the 3rd pneumatic asphalt valve between asphalt delivery pump and the pitch import.
Be provided with two group of first pneumatic asphalt valve, strainer, the second pneumatic asphalt valve, asphalt delivery pump and the 3rd pneumatic asphalt valve between the pitch outlet of described bottom and the pitch import.
A kind of method of pitch rapid melting, when comprising the steps: molten asphalt, when adding solid bitumen, the first pneumatic asphalt valve, the second pneumatic asphalt valve and the 3rd pneumatic asphalt valve are open-minded, start the asphalt delivery pump, eu-bitumen is by the heating of pitch jacket pipe, be filtered, by the pitch rapid melting device that the asphalt delivery pump delivery stirs to band, overheated eu-bitumen washes away solid bitumen, the fusing of accelerating solid pitch, the pitch that fusing is good overflows to upstream device.
Advantageous effect of the present invention: aborning, technical process of the present invention is to change buried pump into common asphalt delivery pump, simultaneously, increase asphalt filter, reduce impurity and enter in the pump, simultaneously, melting tank adopts the tube bundle heater pitch rapid melting device that agitating vane is arranged.The asphalt delivery pump through filter, is extracted eu-bitumen from the pitch outlet of melting tank bottom out, through the heating of pitch jacket pipe, is transported to melting tank, accelerates melting efficiency, reduces equipment failure, convenient maintenance.The fireballing advantage of asphalt melting of existing buried pump pitch rapid melting device has again the advantage of stirring type asphalt rapid melting device failure rate is low.
