Technical field
The invention belongs to pitch processing technique fields, and in particular to a kind of modified pitch second heating apparatus and heating side
Method.
Background technique
Today of construction, the production efficiency and finished product asphaltum of modified asphalt device are widely popularized in Modified Bitumen Pavement
Quality the problem of can not despising at one.To obtain the Modified Bitumen Pavement of function admirable, it is ensured that work progress it is suitable
Benefit carries out, then of crucial importance for the control of temperature in the processing link of modified pitch.
The fusing point of SBS modifier is at 180 DEG C or so, however the heating temperature general control of matrix pitch (No. 70) is 145
DEG C~155 DEG C.It must be discarded when matrix pitch is heated to 195 DEG C, main cause is that high temperature can accelerate lightweight in matrix pitch
Situations such as oil component volatilizees, and leads to ageing of asphalt, oxidation, coking appearance, the indices of pitch can all reduce.
In the prior art, for bituminous pitch storing in sleeping tank, sleeping tank not only has the function of storage, is also equipped with the function of heating,
The heat medium of sleeping tank is conduction oil.Asphalt heating temperature should be controlled at 150 DEG C or so before producing.SBS modifier, which mixes to match, dissolves each other
It is preceding matrix pitch is lifted temperature to rapidly again 185 DEG C reach mix with require.
Bituminous pitch storing and heating are carried out using 50 tons of sleeping tanks in traditional handicraft, specifically: thermally conductive oil temperature is risen to 240
DEG C, because sleeping tank is a whole inner cavity, in heating process in order to make matrix and conduction oil uniformly, sufficiently heat exchange, the can body body that crouches carries out
Agitating device inside rotation either starting makes materials inside constantly overturn, switch.Sleeping tank heating about needs 5 hours could
Pitch is added to 185 DEG C from 150 DEG C.Conduction oil will be kept temperature 5 hours or more in 240 DEG C, and thermal energy consumption is big.Pitch adds
The hot time is long, and not only working efficiency is slow, and pitch (is up to more than 5 hours) more than 150 DEG C at a high temperature of long-time and also results in
Ageing of asphalt influences quality control.
