Description
Technical field
The invention belongs to ground surface material technical field, and in particular to a kind of full-closed zero discharge continuous prodution modified pitch
Device and method.
Background technology
It is right as the trend on China's road construction " high-quality road ", " environment-friendlyroad road ", " ecological road ", " characteristic road " is increased rapidly
The performance of asphalt pavement material proposes requirement higher, to asphalt pavement material production system and asphalt pavement construction operation
Energy-conserving and environment-protective it is also proposed requirement higher.
In order to adapt to the demand in pavement material market, SBS modified pitch, SBS asphaltum with high viscosity, rubber powder modified asphalt, coloured silk
All kinds of modified pitch such as color pitch, warm-mixed asphalt are more and more applied, and are allowed to produce the process units of modified pitch,
Increased rapidly.However, current modified asphalt production device, is produced using pot type gap method, technology controlling and process temperature
Degree is all controlled more than 175 DEG C, is not only consumed energy big, and smoke pollution is serious, can also cause the aging of modified pitch, influences product matter
Amount.And it is current, reply modified pitch produces waste gas also not effectively eliminate measure when producing and paving.
The content of the invention
It is an object of the present invention to provide a kind of device and method of full-closed zero discharge continuous prodution modified pitch.
The device of the full-closed zero discharge continuous prodution modified pitch that the present invention is provided, its structure and process chart are such as
Shown in Fig. 1.The device is by three bitumenpumps, forced feed machine, a reciprocating spiral mixing machine, a single-stage high shear
Mulser, a combined static blender, a multi-stage high shear mulser and according to technological requirement connect above equipment
Pipeline composition；Wherein, bitumenpump 1, forced feed machine 2 connect reciprocating spiral mixing machine 3, reciprocating spiral mixing machine respectively
After 3 connection single-stage high-shear emulsion machines 4, be sequentially connected bitumenpump 5, combined static blender 6, multi-stage high shear mulser 7,
Bitumenpump 8.The outlet of bitumenpump 8 connects modified pitch storage tank or bitumen concrete mixing station by pipeline.
In the present invention, the single-stage high-shear emulsion machine and multi-stage high shear mulser can use functionally similar colloid mill
Substitute.
The device of the full-closed zero discharge continuous prodution modified pitch that the present invention is provided, produces the specific stream of modified pitch
Journey is as follows：110 DEG C -150 DEG C of matrix pitch temperature from storage tank, by the first bitumenpump（1）Input reciprocating spiral mix
Machine（3）, meanwhile, the SBS and the compound of additive being pre-mixed in proportion, by forced feed machine（2）Add reciprocating
Spiral mixing machine（3）；The mixed material of SBS and additive, in reciprocating spiral mixing machine（3）It is interior mix with matrix pitch after,
It is continuous uninterrupted into single-stage high-shear emulsion machine（4）In, preliminary dispersion, shearing, then by the second bitumenpump（5）It is input to group
Box-like static mixer（6）Be stirred, mix, it is swelling, subsequently into multi-stage high shear mulser（7）, finally by the 3rd drip
Blue or green pump（8）Input storage tank or bitumen concrete mixing station.Realize the purpose of full-closed zero discharge continuous prodution SBS modified pitch.
The composition of SBS of the present invention and additive formulations is（By weight）：
Matrix pitch 80-90 parts；
SBS 2-7 parts；
Additive：Aromatic naphtha or machine oil 4-10 parts；
Additive：Microwax and/or stearic acid 3-10 parts.
Further, in process of production, suitable additive is selected, operation temperature, saving energy consumption can be further reduced.
For example, if additive uses aromatic naphtha and microwax, operation temperature is controlled at 160 DEG C -180 DEG C in addition to forced feed machine；
At this moment matrix pitch temperature is preferably 120 DEG C -150 DEG C.If additive uses machine oil, and microwax and stearic acid, operation temperature
Degree is controlled at 130 DEG C -150 DEG C in addition to forced feed machine；At this moment matrix pitch temperature is preferably 110 DEG C -130 DEG C.
It can be seen that, when additive is machine oil and microwax and stearic acid, the operation temperature of production process can be made to change than conventional
Property 25 DEG C -35 DEG C of asphalt production process reduction, the modified pitch of production can also reduce by 25 DEG C of bitumen concrete mix decking and rolling temperature -
35 DEG C, further energy-saving and emission-reduction.
In the present invention, conduction oil that the control of operation temperature can be configured by present device and its relevant connection pipeline or
Electric heating automatic control system is realized.
The device and method of full-closed zero discharge continuous prodution modified pitch of the invention, changes traditional SBS and is modified
The technique of asphalt production, from the pitch from storage tank to the qualified SBS modified pitch of output, production process is totally-enclosed, no to appoint
What waste gas discharge.Process route is concise, simple to operate simultaneously, and floor space is small, very convenient supporting with bitumen concrete mixing station, does
To with bitumen concrete mixing station simultaneously startup-shutdown production, it is necessary to how many SBS modified pitch just produce how much, reduce pitch or product
Multiple transport and heat influence to product quality repeatedly, it is cost-effective while energy-saving.
