| titleOfInvention | Novel petroleum wax is clear away device |
| abstract | The invention provides a novel petroleum wax removing device which can realize wax removing processes such as wax breaking, wax removing, wax prevention and the like at one time, and the wax removing processes are matched and supplemented with each other in a plurality of wax removing modes, so that the efficient, quick, convenient, self-adaptive and environment-friendly wax removing process is realized. In the paraffin removal process, the chemical paraffin removal and softening layer is used for realizing high efficiency of mechanical paraffin removal, the paraffin removal tool bit can be protected by the chemical paraffin removal and softening layer, and after the mechanical paraffin removal is finished, the biological paraffin removal is used for performing paraffin prevention and paraffin removal treatment on the inner part of the pipeline, so that dead corners and residual paraffin which cannot be touched by the tool bit can be removed. |
