Embodiment 1

[0046] see figure 1 As shown, this embodiment provides a coal pyrolysis rotary kiln, which includes: a horizontal rotary kiln body 1 . The horizontal rotary kiln body 1 includes: a rotary kiln feed end face 2, a feed screw device 3, a flue gas heating pipe (not all are shown), a waste flue gas collection device 4 and a waste flue gas outlet 41.

[0047] The feeding screw device 3 includes a screw feeding shaft 32 , and a first housing 31 is arranged on the outer periphery of the feeding section of the screw feeding shaft 32 . A second housing 5 coaxial with the first housing 31 is disposed on the outer periphery of the first housing 31 , and the first housing 31 is fixedly connected to the second housing 5 . In this embodiment, the length of the first casing extending into the rotary kiln is set to be 100mm longer than the length of the second casing extending into the rotary kiln. Between the first shell 31 and the second shell 5 , that is, the material is not easy to enter...

Embodiment 2

[0064] refer to figure 2 As shown, the difference from Embodiment 1 is that in this embodiment, the fixed position and the relative rotation position of the flexible rubber sealing ring 74 are reversed, and the principle is the same as that of Embodiment 1. In this embodiment, the movable end of the flexible rubber sealing ring 74 is close to the third housing 81 , and the fixed end of the flexible rubber sealing ring 74 is located on the vertical ring 72 on the second housing 5 (there is only one vertical ring). The sealing collar 73 is in contact with the sealing ring 71 (that is, it is a rotating and sealing connection), and one end of the sealing ring 71 is fixedly connected with the outer wall of the third housing 81 . During the operation of the rotary kiln, the up, down, left, and right jumps are flexibly absorbed by the flexible rubber sealing ring 74, and the friction force generated by relative rotation is driven by the shift fork 75 and the shift lever 76, so that ...

Abstract

The invention provides a coal pyrolysis rotary kiln, and relates to the technical field of pyrolysis. The rotary kiln comprises a rotary kiln body, a spiral conveying shaft is arranged at the feeding end of the rotary kiln body, a first shell is arranged on the periphery of the feeding section of the spiral conveying shaft, a second shell is arranged on the periphery of the first shell, and a cavity formed between the first shell and the second shell is a steam outlet channel. The air inlet end of the steam outlet channel communicates with an inner cavity of the coal pyrolysis rotary kiln, and a steam outlet of the steam outlet channel communicates with the outside. The equipment provided by the invention not only saves the original energy for pyrolyzing the free water of the raw coal at a high-temperature section, but also greatly reduces the total gas amount discharged from the gas outlet (because the free water is changed into steam and is discharged from the steam outlet in advance), reduces the purification and separation amount of the treated gas, reduces the size of gas purification and separation equipment, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pyrolysis, in particular to a coal pyrolysis rotary kiln. Background technique [0002] At present, there are a variety of horizontal rotary pyrolysis technologies, but there are problems of high yield of mixed gas and high operating cost of purification and separation of gas. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The object of the present invention is to provide a coal pyrolysis rotary kiln to solve the above technical problems. [0005] The inventors found that all the gases produced in the pyrolysis process, including coal gas and water vapor, are discharged from one gas outlet, which causes the steam and coal gas produced by the free water contained in the raw coal to pass through the high temperature zone of pyrolysis, The free water absorbs more energy and wastes more energy, which is the main reason for the high yield of mixed gas and th...
