A sludge treatment system for drilling engineering mud circulation

Abstract

The invention discloses a sludge treatment system for drilling engineering mud circulation, which includes a vibrating screen and a sedimentation tank, and an inclined confluence pipe and a vertical integrated mixing pipe are arranged between the sludge outlet of the vibrating screen and the sedimentation tank. The integrated mixing pipe is equipped with a spraying device that can spray the agent through the sludge and a mixing mechanism that can evenly mix the sludge and the agent. By setting the converging pipe and the comprehensive mixing pipe, and setting up the spraying device, when the sludge is transported to the sedimentation tank, the agent can be sprayed and added simultaneously, and the mixing mechanism is further set up, which also makes the sludge and the agent mix. It is further mixed evenly under the mixing of the mixing mechanism. Compared with the current direct installation of a stirring device in the sedimentation tank, the volume of the equipment is reduced, the equipment consumables are saved, and the mixing has no dead ends, which improves the mixing effect and achieves environmental protection and green. Exploration purpose.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a sludge treatment system used for drilling engineering mud circulation. Background technique [0002] In drilling engineering such as geological and mineral drilling engineering, mud circulation is an essential and important part. In this process of mud circulation, a certain amount of waste mud sludge will be generated, and these sludges contain many substances harmful to the environment, such as oils, chemical additives, heavy metals (such as mercury, copper, chromium and lead, etc. ), macromolecular organic compounds, alkaline substances, etc., if they are not treated, they are discharged again or left in the sedimentation tank, which will cause secondary pollution and seriously endanger the ecological environment. [0003] With the strengthening of environmental awareness and the requirements of green exploration work, more and more construction sites will add chem...

Problems solved by technology

[0004] In view of the deficiencies and defects in the prior art, the purpose of the invention is to provide a sludge treatment system for drilling engineering mud circulation, which solves the current problem of mud When recycling waste sludge, the sedimentation tank is sprayed with chemicals. In order to make the sludge and chemicals mix well, it is necessary to install multiple mixing devices in the sedimentation tank, and the volume of each mixing device is also relatively large. Not only It causes a certain waste of consumables, and there are many mixing dead angles, which leads to the problem that the treatment of sludge cannot achieve the desired effect
