Pulping equipment is ground in the re-injection of micron order landwaste
Technical field
The utility model relates to a kind of landwaste re-injection operation that is used for the offshore oilfield drilling well and grinds the equipment of landwaste and pulping.
Background technology
Over past ten years; constantly perfect with laws and regulations of improving constantly along with public's environmental protection consciousness; adopt various measures as far as possible landwaste and some other discarded object that drilling well is produced of industrial gas oil cuts to bone, so that protect environment and public safety better.Drilling well, produce refuse mainly refer to after well drilling detritus, drilling well finish residue mud, produce refuses such as sand, cargo tank mud.
The processing of offshore drilling discarded object only limits to discharging, re-injection or transports back on the bank and handle.The offal treatment mode is varied, but concludes, and the discarded object that produces in offshore drilling and the production process is nothing more than three kinds of processing modes are arranged: the one, and qualified discharge, the 2nd, transport back on the bank and handle, the 3rd, be recycled into the stratum.
In first kind of mode,, be difficult to by various circles of society's approval to handling thoroughly because in the processing procedure before mud and landwaste efflux, use a large amount of chemical substances.So new oilfield waste thing processing scheme does not generally consider to handle row sea, back up to standard.
Second kind of processing method also is present domestic landwaste processing method, is to transport landwaste back land, through burning, or other harmless treatment, residue is buried, or be processed into the material of other form.This way reduces the pollution of rubbish to environment to a certain extent, but can not realize " zero-emission " of waste treatment, and in processing procedure, the usually new pollution of other form of association.For example, can generate electricity or, can produce dioxin as cement additive though burn, harmful; Though the discarded object landfill can temporarily be can't see dirt,, not only taken up an area of but also may contaminated environment, to deal with improperly, sewage can permeate the ground, and influences the water quality of underground water source.In addition,, bring very big influence, increased operating cost to operation on the sea because the restriction of operating condition when operation is carried out, is adopted this method at sea.
The third processing method is to be recycled into mud, landwaste and other discarded object in the stratum with enclosed construction under condition of high voltage, discarded object " is come; return and where go " wherefrom, is a kind of processing mode near " zero-emission ", progressively obtains the approval of international community.
