Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0026] Such as Figure 1-3 As shown, the two-stage rotary pyrolysis reactor of the present invention includes a cylinder body 1 and a kiln head cover 2, and the kiln head cover 2 is rotatably connected to one end of the cylinder body 1 through a sealing device 10, and the The upper part of the kiln head cover 2 is provided with an exhaust port 21, and the lower part is provided with a slag discharge port 22 for exhaust and slag discharge. The sealing device 10 may be a commonly used sealing device in the field of rotary kiln, such as a scale-type sealing device, to prevent leakage. The above-mentioned structures are well known in the art and will not be repeated here.

[0027] The pyrolysis reactor also includes a pyrolysis gas outlet 3, a partition 4, an air inlet pipe 5 and a feed pipe 7, and the pyrolysis gas outl...

Abstract

The invention discloses a two-section rotating pyrolysis reactor. The two-section rotating pyrolysis reactor comprises a cylinder body, a kiln hood, a pyrolysis gas outlet, a partition plate, an air inlet pipe, a feed pipe, a first pushing spiral plate, a second pushing spiral plate, a first guide pipe and a second guide pipe. According to the two-section rotating pyrolysis reactor, in the operation process, heating in the cylinder body can be carried out in an internal heating mode, and the heat efficiency is high; basically just the solid-phase heat source in the combustion section enters the pyrolysis section through the first guide pipe, impurity smoke is prevented from being mixed into pyrolysis gas, the quality of pyrolysis products is guaranteed, and subsequent treatment is convenient.

Description

technical field [0001] The invention relates to rotary pyrolysis equipment, in particular to a two-stage rotary pyrolysis reactor. Background technique [0002] The rotary reactor is a device for thermal processing of powdery materials, and has been widely used in nonferrous metallurgy, refractory materials, cement, chemical and papermaking industries. With the technological advancement of unconventional energy, rotary reactors are now also being used in the pyrolysis of oil shale to produce shale oil, supplementing the demand for conventional energy in economic development. Related products such as the externally heated multi-stage rotary furnace developed by Beijing Coal Chemical Industry Co., Ltd. and the externally heated rotary kiln reactor developed by Xi'an Sanrui Industrial Co., Ltd. [0003] According to the heat supply mode required for the pyrolysis process, the above pyrolysis reactors include: the first type of external heat type in which the heat medium does n...
