Abstract
The invention relates to a method for treating drilling wastes in petroleum and gas exploitation, especially a solidification treatment method and an apparatus thereof. The treatment method adopts delivering the drilling wastes to a high speed disintegrator to smash, at the same time spraying firming agent to the high speed disintegrator. The apparatus comprises a delivery conveyor within a receiving bucket, a bucket elevator, a feeding spiral conveyer, a high speed disintegrator and a firming agent conveyer. The invention smashes wastes to form numerous small particle, after that, carries out physico-chemical reaction with the firming agent, and packages the small particle. Accordingly, the invention has good solidifying effect correspondingly, can reduce firming agent application amount, wherein the solidified body extract will not pollute the environment. Meanwhile, the apparatus of the invention with high mechanization degree, may form automatic integration, is convenient for achieving solidification treatment along with the drilling process without generating environment pollution.
Description
Technical field
The present invention is the treating apparatus of drilling wastes in oil, the natural gas extraction, particularly adopts to solidify the device of handling.
Background technology
Along with oil, gas are exploited in a large number, waste liquid of drilling is because seriously polluted, and it is treated as a great problem.At present waste liquid of drilling is handled the general centrifuge that adopts and carry out Separation of Solid and Liquid, isolated liquid is adopted methods such as gel breaker and little electrolysis handle; Adopt the adding curing agent to be cured to isolated discarded object (based on mud).Existing curing handled general process and adopts curing agent directly added to stir in the discarded object and get final product.The corresponding curing agent addition height that exists, the solidification effect instability, firming body is prone to leachate can not reach environmental requirement, and firming body is handled problems such as inconvenience, and existing fixing the handles device is simple and crude, and labour intensity is big, forms bigger pollution with boring to handle.
Summary of the invention
The objective of the invention is to overcome above-mentioned prior art deficiency, a kind of drilling wastes fixing the handles device is provided, the feasible firming body non-environmental-pollution that solidifies after handling can be disposed on the spot, and its plant automation degree height of while can be with creeping into the row processing.
Solution of the present invention is: a kind of drilling wastes fixing the handles device, be characterized in comprising the case that connects material, the interior outfeed belt conveyor of case connects material, the bucket elevator that matches with outfeed belt conveyor, the drilling wastes that bucket elevator is promoted is transported to the loading screw conveyor in the high speed disintegrator, the high speed disintegrator that drilling wastes is pulverized, stirred, the curing agent batcher of connecting by pipeline and high speed disintegrator; Wherein, drilling wastes is transported to high speed disintegrator
Interior simultaneously to high speed disintegrator
The curing agent of interior spray drilling wastes volume 10-20%.
The present invention is transported to drilling wastes in the high speed disintegrator and pulverizes, and makes discarded object form numerous small particles, sprays into curing agent simultaneously, curing agent and discarded object generation physical-chemical reaction, and parcel done small particle, thus reach good solidification effect.The straying quatity of curing agent can be selected according to the density of drilling wastes, when drilling wastes density is 1.2～1.5g/cm
3The time, the curing agent straying quatity is 20% of a drilling wastes volume; When drilling wastes density is 1.6～1.9g/cm
3The time, the curing agent straying quatity is 15% of a drilling wastes volume.
Its course of work is: after pouring drilling wastes into the case that connects material, by the material loading conveyor delivery in the hopper of bucket elevator, after promoting, bucket elevator delivers to loading screw conveyor, be transported to pulverizing in the high speed disintegrator, stir by loading screw conveyor, the curing agent batcher sprays into curing agent by the working space of pipeline in high speed disintegrator simultaneously, and the drilling wastes that is ground into micro particles is cured and extrudes from the discharging opening of high speed disintegrator after agent is wrapped up.
Can connect a self-overflow type batch mixer at the discharging opening of high speed disintegrator in the device of the present invention, the firming body that the high speed disintegrator discharging opening is extruded further mixes in the self-overflow type batch mixer, make the particulate of discarded object sufficient the contact be arranged with curing agent, along with the firming body in the high speed disintegrator is imported in the self-overflow type batch mixer, firming body in the self-overflow type batch mixer is extruded to outlet gradually, reaches to discharge the firming body that is cured.
Advantage of the present invention is: because high speed disintegrator is pulverized drilling wastes, make discarded object form numerous small particles, after spraying into curing agent, small particle is wrapped up, thereby reach good solidification effect.It is stable to solidify the back solidification effect, and the curing agent addition reduces greatly than existing curing mode, and the firming body leachate reaches environmental emission standard, can not pollute environment, and firming body can be directly used in and fires common standard brick etc.Through many batches of firming bodys are detected, its pH value is 7-9, and lead content is 0-0.067mg/L, and COD is 12-80mg/L, and total chrome content is 0.012-0.129mg/L.Device for mechanical degree height of the present invention can form automatic integratedization, is convenient to solidify processing, non-environmental-pollution with creeping into row.
Description of drawings
Fig. 1 is apparatus of the present invention distribution schematic diagram;
Fig. 2 is Fig. 1 vertical view;
Wherein: 1-self-overflow type batch mixer, 2-high speed disintegrator, 3-loading screw conveyor, 4-bucket elevator, the 5-case that connects material, 6-outfeed belt conveyor, 7-curing agent conveyer, 8-curing agent conveyance conduit.
The specific embodiment
Embodiment 1: it is to be 1.3g/cm with density that drilling wastes solidifies facture
3Drilling wastes send in the high speed disintegrator and pulverize, in high speed disintegrator, spray into curing agent simultaneously, the curing agent straying quatity is 20% of a drilling wastes volume.Its processing procedure such as Fig. 1, shown in Figure 2, after pouring drilling wastes into the case 5 that connects material, open outfeed belt conveyor 6, discarded object is transported in the hopper of bucket elevator 4, pour out after by bucket elevator 4 it being promoted, by loading screw conveyor 3 discarded object is transported to pulverizing in the high speed disintegrator 2, stir, curing agent is sprayed in the high speed disintegrator 2 pulverizing the discarded object parcel curing that the back forms particulate by curing agent conveyance conduit 8 by curing agent conveyer 7 simultaneously, firming body after the curing enters self-overflow type batch mixer 1 from the discharging opening of high speed disintegrator and further solidifies, and is extruded from the outlet of self-overflow type batch mixer 1 gradually at last.
