Drum screening machine and application thereof in oil sludge treatment

Abstract

The invention provides a drum screening machine and an application method thereof in oil sludge treatment. The drum screening machine is mainly characterized by comprising a front crushing and tearing device and a rear treatment device, wherein a drum body comprises a screen-mesh-containing drum body and a screen-mesh-free drum body which are connected through subsection welding or through a connecting part, a water spraying device penetrating through the drum body or arranged in a subsection manner is arranged in the drum body, a feeding device is mounted at a feed port in the front end of the drum body, a receiving hopper capable of separating light and heavy impurities is mounted at an impurity discharge port in the rear end of the drum body, and a discharge hopper is mounted at a qualified material discharge port in the lower part of the screen-mesh-containing drum body. The drum screening machine has the advantages that the operation is simple, safe and reliable, oil sludge is sent to the front crushing and tearing device to tear and crush large stone particles, tiles, plastic cloth, woven bags and the like in the material, a to-be-treated material is uniformly sent into the feeding end by a feeding machine, qualified materials discharged from the qualified material discharge end are sent for follow-up treatment, and meanwhile, clean combustible materials with the recovery value are discharged in a classified manner from the impurity discharge end.

Description

technical field [0001] The invention relates to a new type of drum screening machine and its application in sludge treatment, especially a new type of drum screening machine and its application technology, which can process a large amount of sludge in oil fields and petrochemical systems with high efficiency, and can be used as sludge reduction Chemical treatment and various sewage sludge treatment methods, such as pretreatment of extraction method, water washing-conditioning method, etc. Background technique [0002] With the development of the petroleum industry, a large amount of sludge will be produced in the process of petroleum exploration, refining, storage and transportation. The amount of sludge produced in my country every year is not less than 4 million tons, which brings serious environmental protection problems. In recent years, all kinds of sewage sludge treatment methods have been researched and developed at home and abroad, but any treatment method requires p...

AI Technical Summary

Problems solved by technology

The currently commonly used sludge pretreatment equipment has the disadvantages of small processing capacity, long processing time, high energy consumption, and poor treatment effect. Development, the inability to timely dispose of the sludge generated during normal production in the petrochemical industry and accumulated over the years has made the petrochemical industry more and more pressured on environmental protection issues
