Embodiment 1

[0030] figure 1 It is a structural schematic diagram of a carbon material vibrating pyrolysis tower provided by Embodiment 1 of the present invention. The carbon material vibrating pyrolysis tower provided by the present invention comprises: casing 1, at least five vibrating beds 2, radiant tubes 3 with adjustable heating temperature; the inside of said casing 1 is isolated from the outside air; at least five of said The vibrating beds 2 are arranged in a zigzag from top to bottom in the casing 1; each vibrating bed 2 is provided with a feeding port 4; each vibrating bed 2 is provided with the The radiant tube 3; the heating temperature of the radiant tube 3 increases from top to bottom; wherein, the heating temperature of the radiant tube 3 at the bottom layer is 600°C-750°C.

[0031] In the carbon material vibrating pyrolysis tower provided in the first embodiment, in the coal pyrolysis device provided above in the present invention, the carbon material vibrating pyrolysis ...

Embodiment 2

[0033] see figure 1 as well as figure 2 As shown, on the basis of the first embodiment above, the carbon material vibration pyrolysis tower provided by the second embodiment of the present invention also includes a water cooling jacket 5 and a distributor 6; the distributor 6 is located at the bottom of the vibration Below the feeding port 4 of the bed 2, and arranged in a zigzag shape with the vibrating bed 2 on the lowermost floor; the distributor 6 is provided with a plurality of lower leakage holes 7; the water cooling jacket 5 is located in the distribution 6, and a plurality of cooling passages 8 extending in the vertical direction are formed in the water cooling jacket 5; Sweeper 9 with surface movement.

[0034] In this second example, since the temperature of coal can reach 300°C-750°C during pyrolysis, in order to prevent the semi-coked coal generated after coal pyrolysis from burning at this temperature, the semi-coked coal generated by coal pyrolysis needs to be...

Embodiment 3

[0039] figure 1 and image 3 It is a structural schematic diagram of the carbon material vibrating pyrolysis tower provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiment two, see figure 1 as well as image 3 As shown, in the carbon material vibrating pyrolysis tower provided in the third embodiment, a water-cooled box 10 is also included; a water-cooled chamber 11 is formed in the water-cooled box 10 to communicate with the cooling passage 8 and the outside world; the water-cooled A screw pusher 12 for pushing coal to the outside is also arranged in the chamber 11 .

[0040] In the third embodiment, since the temperature of the semi-coked coal needs to be rapidly reduced to below the ignition point of the semi-coked coal during the cooling process, in order to increase the cooling rate of the semi-coked coal, a carbon vibrating pyrolysis tower is added Water cooling box 10. The water-cooled box 10 forms a water-cooled chamber 11 ...

Abstract

The invention relates to the field of coal chemical industry, and in particular relates to a carbon substance pyrolysis method and a carbon substance vibration pyrolysis tower. The carbon substance vibration pyrolysis tower comprises a housing, at least five vibration beds and heating-temperature-adjustable radiant tubes, wherein the housing is internally isolated from external air; the at least five vibration beds are arranged in a zig-zag shape in the housing from top to bottom; each vibration bed is provided with a material outlet; the radiant tubes are arranged above the vibration beds; the heating temperatures of the radiant tubes rise gradually from top to bottom; and the heating temperature of the bottom radiant tube is 600-750 DEG C. A carbon substance rolls down from top to bottom on the multiple vibration beds of the vibration tower; and the temperature of the carbon substance gradually rises to 600-750 DGE C from the normal temperature when the carbon substance rolls down and is heated by the radiant tubes on the vibration beds, so that the mass separation of volatile matters in coal pyrolysis can be avoided, and furthermore, various problems caused by the bursting and the breaking of brown coal in the background technology can be solved.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a carbon substance pyrolysis method and a carbon substance vibration pyrolysis tower. Background technique [0002] The pyrolysis of carbon substances (such as lignite) is a common method to improve the quality of carbon substances; in related technologies, for the pyrolysis of lignite, the usual practice in the prior art is to put lignite into equipment at a certain fixed temperature , so that the lignite is pyrolyzed at this temperature, so as to obtain the desired different lignite processed products, such as semi-coke. [0003] However, in the existing pyrolysis method, the moisture inside the coal block will vaporize rapidly at the pyrolysis temperature, causing the internal pressure of the coal block to rise. The diffusion speed from the inside to the outside in the capillary and the internal pressure value are too high, resulting in the bursting of the coal block, an...
