Problems solved by technology

[0005] This kind of coal material decomposition equipment can solve the problem of decomposition of inferior coal, especially pulverized coal, but the relatively complicated internal heating mechanism and distribution mechanism are likely to cause uncertainty of heating temperature in the production process and instability of normal production; especially During the decomposition process of inferior coal, the temperature control and adjustment of different areas inside the closed kiln body in a high-temperature environment is a relatively difficult problem to solve

Abstract

The invention discloses a low-quality coal pyrolysis device, which comprises a closed kiln body with a material inlet and a material discharge port. A high-temperature gas pipeline is arranged in the closed kiln body, and the low-quality coal formed between the high-temperature gas pipeline and the inner wall of the closed kiln body is pushed forward. Decomposition channel, the closed kiln body is provided with a decomposition gas collection pipe connected with the inferior coal propelling decomposition channel, the inferior coal pyrolysis device also includes a high-temperature gas generator, the high-temperature gas generator and the high-temperature gas pipeline are connected through a high-temperature gas distribution cover, The high-temperature gas distribution cover is connected with the closed kiln body in a circumferential seal. In the present invention, a high-temperature gas generating device is arranged, and the high-temperature gas generating device is connected with a high-temperature gas pipeline through a high-temperature gas distribution cover, so that the reliability and stability of the low-quality coal pyrolysis device are fundamentally improved.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of coal materials, energy saving and emission reduction, and in particular to a low-quality coal pyrolysis device. Background technique [0002] In my country, low-quality coal reserves represented by lignite and low-metamorphism bituminous coal account for more than 55% of the total coal resources, mainly distributed in eastern Inner Mongolia, Yunnan, Xinjiang and the Ordos Basin. As high-metamorphic coals are used less and less, the optimal utilization of low-quality coal is becoming increasingly important. Compared with the technical or economic problems in the direct utilization of low-quality coal, the graded and quality-based utilization of low-quality coal after upgrading should become an important direction. As a technology that is later than coal gasification technology to achieve industrialization, the upgrading of inferior coal is virtually endowed with the expectatio...
