The invention relates to an agricultural waste comprehensive utilization technology and specially, relates to a preparation method of modified biological tar asphalt. The preparation method comprises the following steps of 1, a biological asphalt preparation process comprising removing a fraction having a temperature below 220 DEG C of biological tar by normal pressure distillation and collecting a residue, wherein the residue is biological asphalt, 2, a heating process comprising heating the residue so that the residue becomes liquid, and 3, a modifier addition process comprising adding 1 to 3% of a chloroprene rubber latex asphalt modifier into the liquid obtained by the step 2 according to a certain ratio, and heating with uniform stirring to obtain the modified biological tar asphalt. The preparation method realizes effective utilization of biological tar, solves the problems of biological tar secondary pollution in agricultural waste carbon gasification technology utilization, changes waste into valuables, and improves the economic benefit of the agricultural waste carbon gasification technology utilization.
Description
Technical field
The present invention relates to a kind of agricultural wastes comprehensive utilization technique, particularly a kind ofly agricultural wastes are fully utilized the biological tar that produces in the switching process convert biological modified by tar bituminous making method to
Background technology
Biological tar is a kind of important chemical material, and quality is higher than coal tar, its complicated component; Each component content of the biological tar of different starting material gained is different, wherein contains 5～6% the hydro carbons of having an appointment, 2～3% alcohols; 40～60 creosote, a small amount of aldehydes exists with liquid state when being lower than 200 ℃; Pyrolysis takes place in the time of more than 200 ℃, and pyrolysis becomes micro-molecular gas.Pressing in the biological tar distillation cut of normal pressure temperature collection, is the sour water cut below 110 ℃, is light oil distillate in the time of 110～190 ℃, is the creosote cut in the time of more than 190 ℃, also has higher residual the heating up in a steamer of thermal value.The sour water cut that wherein biological tar distillation obtains can be processed with biological acetic acid; Light oil distillate can be used as the floatation frother that fuel or non-ferrous metal ore are used; All the other cuts can further convert biological stopper, biological anti-oxidant, industrial creosote and liquid fuel etc. to, and its residue is that biological pitch can be used for making biological modified by tar bituminous raw material.
In the existing agricultural wastes charcoal gasification system; The method of washing decoking is generally adopted in the separation of combustion gas and purification, and the waste water that is mixed with biological tar and wood vinegar is in a large number entered the farmland, collects utilization and abandons it; Cause soil and water source severe contamination, agroecological environment is done great damage.
How biological tar is effectively utilized; Solve agricultural wastes charcoal gasification technology and utilize in the process, secondary pollution problem turns waste into wealth; Agricultural wastes charcoal gasification technology is applied, promoted the development of agricultural wastes utilization of resources technology to have vital role.
Existing modifying asphalt is to mix rubber, resin, high molecular polymer, levigated rubber powder or other fillers at petroleum pitch, coal-tar pitch or wood tar pitch; Or take to measures such as pitch mild oxidation processing the asphaltic binder that makes the performance of pitch or asphalt be improved and process.Modifying asphalt can improve the road surface resistance to flow, the ability of anti-rut under the high temperature; Improve flexibility and elasticity, the i.e. ability of cracking resistance under the low temperature; Improve the abrasion performance ability and increase the service life.Also do not find the concrete process method of producing modifying asphalt at present with biological tar (the careless tar that is produced with agricultural wastes pyrolysis such as stalks).
Summary of the invention
Main purpose of the present invention is; Overcome in the existing agricultural wastes charcoal gasification technology utilization; The waste water that contains biological tar and wood vinegar is in a large number entered the farmland, and severe contamination soil and water source work the mischief to agroecological environment; Utilize biological tar to make biological modified by tar bituminous making method and provide a kind of, technical problem to be solved be make produced in the agricultural wastes charcoal gasification technology impurity--biological tar is utilized effectively.
Biological modified by tar bituminous making method provided by the present invention is realized by following technical scheme.
A kind of biological modified by tar bituminous making method, comprising following steps:
