Problems solved by technology

The heating method of these processes is generally heat conduction, that is, the material environment must be preheated first, and then the material is heated by heat conduction, convection and radiation, so that the material is carried out in stages and parts, and cannot be carried out as a whole. Therefore, heating Less efficient and prone to secondary reactions in the heating protocol

Abstract

The invention discloses coal microwave dry distillation equipment and a coal microwave dry distillation treatment method thereof. The coal microwave dry distillation equipment comprises a feeding system (1), a microwave dry distillation furnace (2), a microwave generator (3), a dedusting system (4), a tar and gas cooling and collection system (5), a tailings cooling system (6) and a discharging system (7), the microwave generator (3) is mounted on the microwave dry distillation furnace (2) which is connected with the dedusting system (4), the tar and gas cooling and collection system (5) is connected with the dedusting system (4), the tailings cooling system (6) is connected with the microwave dry distillation furnace (2), and the discharging system (7) is connected with the tailings cooling system (6). High-power microwave technology is utilized in a sealed state to heat low-quality coal, and low-quality coal less than 5% in water content in an oxygen isolating state is heated to 600 DEG C for pyrolysis to obtain high-added-value products including tar, semi-coke and coal gas. By the use of the coal microwave dry distillation equipment and the coal microwave dry distillation treatment method, harmless and reductive treatment of coal resources can be realized, and the problem that the low-quality coal is low in heat value and causes serious burning pollution can be solved.

Description

technical field [0001] The invention relates to coal processing equipment, in particular to coal microwave dry distillation equipment and a coal microwave dry distillation treatment method thereof, belonging to the technical field of microwave heating. Background technique [0002] The direct combustion of low-rank coal not only wastes a lot of energy, capital and equipment, but also seriously pollutes the environment. Harmful gases such as dust, sulfur oxides, nitrogen oxides, and carbon monoxide produced during incomplete combustion in the combustion products are discharged into the atmosphere. It will cause dust pollution and gas pollution. With the development of the economy, the improvement of people's living standards, the strengthening of environmental protection awareness, and the country's requirements for the rational and efficient comprehensive development and utilization of coal resources, low-rank coal carbonization will inevitably receive more and more attentio...
