Oily sludge treatment machine

Abstract

The invention discloses an oily sludge treatment machine for an oil field. The machine comprises a fixed frame, wherein a sludge bin is arranged at the top of the fixed frame and connected with a stirrer, additive feeding hoppers are connected with front and rear sides of the stirrer respectively, the left side of the stirrer is connected with a conveying belt lifter, the conveying belt lifter isconnected with a feeding inlet of a sludge forming machine, the sludge forming machine is arranged on the top of the right end of a sludge drying machine, the sludge drying machine is connected with external waste gas treatment equipment by at least two steam outlet pipes arranged on the top of the sludge drying machine, and a discharging inclined plate is arranged at the bottom of the left end ofthe sludge drying machine. By means of the arrangement, forming and step-by-step drying operation of oily sludge are achieved, the oily sludge can be effectively treated and finally dried, and the waste gas generated in the drying process is directly discharged by the external waste gas treatment equipment. The oily sludge treatment machine is ideal.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment equipment, and in particular relates to an oily sludge treatment machine used in oil fields. Background technique [0002] As we all know, in oil fields, oily sludge exists as a kind of petroleum appendages. This kind of oily sludge has various types and complex properties, and is listed as hazardous solid waste. Its treatment technology has increasingly attracted people's attention and attention. [0003] Due to the high viscosity of oily sludge, it is difficult to dry it using traditional drying methods and equipment such as drum dryers and paddle dryers. For this type of sludge, the commonly used drying technologies can be roughly divided into the following categories: Several: [0004] 1. Incineration method: This process causes serious secondary pollution, and the crude oil with high economic value in the sludge has not been recycled; 2. Pyrolysis method: This method has a fast proc...

AI Technical Summary

Problems solved by technology

[0004] 1. Incineration method: This process causes serious secondary pollution, and the crude oil with high economic value in the sludge has not been recycled; 2. Pyrolysis method: This method has a fast processing speed and a more thorough treatment of sludge. The disadvantage is that the reaction conditions are high, the operation is complicated, the equipment investment is huge, the energy consumption is high, and the secondary pollution of the atmosphere is easy to be generated if the treatment is not good.

The remaining processing technologies are currently limited to laboratory research, and it is difficult to achieve industrial application
