Ether and polyoxyethylene sorbitan monooleate mix, wherein, the Volume fraction of each material is：1-2:0.5-1:
0.2-0.4:1-2。
Wherein, the emulsifying agent by APES, polyacrylamide, NPE mixing and
Into wherein the Volume fraction of each material is 1-2:0.5-0.8:1.5-3.
In addition, the invention provides the preparation method of the cleaning agent for high-wax oil volume pipe, wherein, it is prepared
Method is：
1）Under normal temperature, surfactant and emulsifying agent are proportionally added into water, 10- is stirred with 250-300r/min speed
15min, obtain mixture A；
2）Cosolvent is proportionally added into mixture A and stirred, obtains mixture B；
3）Under conditions of stirring, solvent is slowly added into mixture B, is stirred until homogeneous and can obtain emulsion-type wax removal
Agent.
In addition, present invention also offers the application method of described volume pipe cleaning agent, first by volume pipe with 50-60 DEG C
Hot water continuous flushing 5 hours, then the cleaning agent is configured to the cleaning fluid that volumetric concentration is 10% 5 are persistently cleaned to volume pipe
My god, finally with identical hot water injection 2 hours.
Beneficial effects of the present invention are：The present invention obtains emulsion cleaner the speed of paraffin dissolution and reaches more than 0.4g/min, closes
Mouth flash-point is higher than 25 DEG C, no organochlorine, carbon disulfide, can effectively clean volume pipe wax deposition, has safety and environmental protection, stability good
Feature；The present invention has the advantages of cleaning temperature is low, and concentration is small, and scavenging period is short, and cleaning efficiency is high, cheap；
Mix oil transportation and Dongying oil depot for Gudao crude, isolated island oil recovery factory multi-purpose station and mix on the treatment effect of oil transportation, effect considerably beyond
Common paraffin remover.
