Embodiment Construction

[0018] attached figure 1 It is the working principle diagram of the 5-layer drum oil shale retort furnace, attached figure 2 It is a structural schematic diagram of a 5-layer drum oil shale retort furnace. It can be seen from the figure that the oil shale is broken into small pieces smaller than 25 mm, and the oil shale is sent to the top hopper (2) of the carbonization furnace through the ore conveying device (1), and the oil shale is sent to the top hopper (2) of the carbonization furnace by the feeder (3). Put into the retort furnace, fall into the first layer of drums (6), the drum axis (16) is driven by the motor (18) through the gearbox (17), rotates continuously, and is installed on the drum spokes (20) The drum also rotates accordingly, and the oil shale in the drum rolls continuously in the drum. A drum lifting board (22) is installed on the drum wall, and air holes (19) are opened on the drum lifting board (22). The air flow enters the drum from the pores (19), fu...

Abstract

The invention relates to a process and device for refining oil by destructive distillation of oil shale with the thickness of less than 25mm. The process is characterized by transporting the oil shale by utilizing multiple layers of rotary drums; and continuously rolling the oil shale in the rotary drum depending on mechanical force, and carrying out gas-solid relative current heat exchange on the oil shale and a gas heat carrier so as to achieve the destructive distillation. 3-7 layers of rotary drums are arranged in a retort furnace and are distributed in a slightly inclined mode, wherein the slope degree is less than 5 degrees, and the rotary drums are arranged in 1-3 rows; and a rotary shaft is arranged in the middle of the rotary drum, and the rotary drums are fixed on a centre shaft by spokes, and the centre shaft of the rotary drum is connected with a speed changing box and an electromotor. According to the invention, the resource utilization is high and is 100%, and the oil yield is high and can reach above 90%; and the structure is simple, the operation is convenient, the investment is less, and the efficiency is high, thus the process and device provided by the invention are suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a technique and equipment for dry distillation and refining of oil shale, which belongs to the dry distillation technique and device using gas as heat carrier in the oil shale dry distillation industry. Background technique [0002] At present, oil shale carbonization furnaces at home and abroad can be divided into two categories, one uses solid as heat carrier, and the other uses gas as heat carrier. The carbonization furnace with solid as the heat carrier is characterized by using solid medium as the heat carrier for oil shale carbonization. The heat required for carbonization comes from the contact heat conduction with the solid heat carrier. The carbonization furnace with gas as the heat carrier is characterized by using gas The medium is the heat carrier of oil shale carbonization, and the heat required for carbonization mainly comes from the convective heat exchange and contact heat conduction with the gas heat carrier. ...
