Problems solved by technology

[0005] This kind of coal material decomposition equipment can solve the decomposition problem of low-quality 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 in the decomposition process of low-quality 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 inferior coal decomposition equipment. The inferior coal decomposition equipment comprises an airtight kiln body which is provided with a feed opening and a discharge opening, high temperature gas pipelines are arranged in the airtight kiln body, an inferior coal propulsion decomposition channel is formed between the high temperature gas pipelines and the inner wall of the airtight kiln body, a decomposition gas collection pipe communicated with the inferior coal propulsion decomposition channel is arranged on the airtight kiln body, and one end of the airtight kiln body is provided with a high temperature gas generation device which is connected with the high temperature gas pipelines. According to the inferior coal decomposition equipment, due to the fact that the high temperature gas generation device is arranged and connected with the high temperature gas pipelines, and therefore the reliability and the stability of the inferior coal decomposition equipment 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 decomposition device. Background technique [0002] In my country, low-quality coal reserves represented by lignite and low-metamorphic 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 coals becomes 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 low-quality coal is virtually endowed with the expecta...
