Problems solved by technology

However, due to problems such as coking in the furnace, serious metal corrosion on the radiation heating surface, dust on the convection heating area, large heat loss from mechanical incomplete combustion, and difficulty in burning low calorific value oil shale, it is difficult to develop
The bubbling fluidized bed combustion of oil shale (boiling layer process. China Industry Press, 1965, pp. 175-214) has realized the low-temperature combustion of oil shale, and effectively solved the problem of oil shale in bed-burning furnace and chamber-burning furnace. Coking in the furnace caused by rock combustion, severe metal corrosion on the radiation heating surface, ash on the convective heating area...

Embodiment Construction

[0010] The technical process of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] figure 1 It is technical process of the present invention. Such as figure 1As shown, the oil shale used for refining shale oil with a particle size of 0-80mm is sent into the oil shale hopper 1, and the oil shale fine slag with a particle size of less than 8mm is sent into the oil shale hopper through the crushing and screening machine 2. Shale fine slag waste material hopper 3, the oil shale with a particle size greater than 8mm is sent into the oil shale hopper 4, and the conveyor sends the oil shale with a particle size greater than 8mm from the top to the vertical oil shale retort furnace 5 for carbonization , the carbonization temperature of the oil shale carbonization furnace is preferably 450-550°C, the heat required for the carbonization comes from the heating furnace 8, the gas required for the heating furnace comes from the s...

Abstract

The comprehensive optimized oil shale utilizing method includes crushing and sieving oil shale ore, dry distilling the 8-80 mm size component in retort furnace to produce shale oil and fuel gas, crushing the semicoke waste into 8 mm below size, mixing the crushed semicoke waste and 8 mm below size waste grain from oil refining to form mixed fuel for the circulating fluidized bed boiler, using the produced steam partially for externally supplying and partially to drive turbine generator, and using the cinder in producing cement, haydite and building block. The present invention provides one new way for comprehensive utilization of giant oil shale resource.

Description

technical field [0001] The invention relates to a method for comprehensive optimization and utilization of oil shale, which can realize all-round comprehensive optimization and utilization of oil shale resources in oil production, power generation, heat supply and building materials, and belongs to the technical field of oil shale resource utilization. Background technique [0002] Oil shale is an important potential energy source with huge reserves. Among fossil fuels, its reserves are converted into calorific value and rank second only to coal. If it is converted into shale oil, the world's oil shale reserves are about 475 billion tons, equivalent to 5.4 times the proven recoverable reserves of natural crude oil in the world. The development and application of oil shale has a history of more than 200 years, and the development and utilization of oil shale energy mainly lies in the production of shale oil. The refining process of shale oil usually adopts the dry distillati...
