Problems solved by technology

The process before suspension roasting is to grind the oil shale ore into powder, and make the composition of the powder relatively stable; however, affected by the oil shale composition of each mine or the mining process, it is inevitable that its composition will fluctuate greatly, especially It is the fluctuation of oil content, carbon content and hydrogen content, which will make roasting operation difficult, and also affect oil grade, oil production rate and operating cost

Abstract

The invention discloses a device and a method for homogenizing oil shale powder. The device is characterized by mainly comprising a round bin, and a homogenizing chamber, a discharging chamber, a high-position unloading device, a low-position unloading device, a soft inflation system, a forced inflation system, a plurality of open type inflation boxes and a roots blower which are arranged in the round bin. By using the device, inflation air passing through the inflation boxes enters the oil shale powder in the round bin so as to be uniformly and fully mixed with the oil shale powder; then the mixed oil shale powder is continuously unloaded by the high-position unloading device connected with the round bin; as the device and the method are used, the fluctuation range of the oil content of the oil shale powder can be reduced to be below + / -0.2%, and the homogenizing coefficient can be up to 8-13.

Description

technical field [0001] The invention relates to a homogenization device and a homogenization method for powder materials, in particular to a homogenization device and a homogenization method for oil shale powder materials. Background technique [0002] Petroleum is one of the important strategic resources of our country. In 2012, my country's demand for crude oil exceeded 500 million tons, while imported crude oil was 280 million tons, with a foreign dependence of 56%. With the continuous exploitation of crude oil, my country's foreign dependence on crude oil will become higher and higher. [0003] my country's oil shale reserves are huge, and oil shale extraction will be an important supplement to crude oil. At present, the technical level of my country's oil shale extraction industry is backward. Most of them are produced by shaft furnaces, and a few are produced by fluidized furnaces. However, no matter which production method is used, it will cause waste of small partic...
