Novel carbon dioxide extraction device

Abstract

The invention provides a novel carbon dioxide extraction device. The device comprises a support frame, an upper filter cartridge, a lower filter cartridge, a connecting disc and a buffer tank, the lower filter cartridge is fixedly mounted on the support frame, and one side of the top of the upper filter cartridge is connected with a slurry input flange and a carbon dioxide discharge flange by bolts, the connecting disc is in transition connection with the upper filter cartridge and the lower filter cartridge by bolts and sealing steel rings, the lower filter cartridge is in fit connection witha liquid inlet tube through an internal thread and an external thread, a motor supporting seat is mounted at one end of the lower filter cartridge through an internal thread and an external thread ina fit manner, a motor is mounted on the motor supporting seat by bolts, a screw conveying mechanism is arranged in the lower filter cartridge, one end of the screw conveying mechanism is fixedly connected with a connecting shaft, and the other end of the connecting shaft is mounted on the output shaft of the motor. The novel carbon dioxide extraction device has the advantages of reasonable design, completion of control of the whole set of the device by one person, safety and reliability in operation, simplicity and convenience in maintenance, and strong generalizability.

Description

technical field [0001] The invention is a novel carbon dioxide extraction device, which belongs to the technical field of drilling cuttings mud oil-water secondary treatment, extraction and drying equipment. Background technique [0002] Supercritical carbon dioxide extraction and separation refers to the fact that carbon dioxide has a special dissolving ability for specific substances in a supercritical state. Using the characteristics of strong penetrating power, high density and solubility of carbon dioxide fluid in a supercritical state, it can be achieved by means of decompression and temperature rise. The physical extraction technology for separating and purifying the extracted substances has the remarkable characteristics of continuous, efficient and pollution-free operation. [0003] At present, the common treatment methods for waste mud drilling cuttings containing oil and water in oilfields are reinjection, incineration or centrifugal separation and oil removal tec...

Problems solved by technology

[0003] At present, the common treatment methods for waste mud drilling cuttings containing oil and water in oilfields are reinjection, incineration or centrifugal separation and oil removal technology. The former treatment process is simple, causing large-scale air, soil and water environmental pollution, which does not meet the environmental protection requirements of oil fields; centrifugal separation and oil removal The technical oil removal is not complete, the daily processing capacity is low, and cannot meet the on-site processing capacity requirements. At the same time, the price is expensive, which is not conducive to large-scale promotion; due to technical and other reasons, a large amount of drilling mud piled up at the drilling site cannot be processed, which not only occupies the limited operating space of the well site , causing waste of resources and polluting the environment at the same time; therefore, the oilfield site urgently needs a technological breakthrough to realize efficient and environmentally friendly drilling mud post-processing equipment to be put into use. For this reason, the present invention provides a new carbon dioxide extraction device
