| Abstract: | Рассмотрен вопрос очистки шахтного метана путем использования гранулированных сорбентов, полученных из угольной пыли. Приведены результаты экспериментов по гранулированию модельного материала, а также представлен анализ популяционного баланса процесса агломерации на основе явления разрушения частиц при ударе. |
| Description: | CMM (Coal Mine Methane) is a strong pollutant of the environment, one of the destroyers of the ozone layer of the atmosphere of the planet. At the same time contains impurities that impair its quality as a fuel. As a part of mine gas, in addition to methane, usually come in different proportions of carbon dioxide, nitrogen, oxygen, water, and other particulate matter. In this connection, it is necessary to create the technology and equipment that allow methane to clean the impurities and provide the necessary quality of this energy for later use. The solution of mine methane cleaning by using granulated sorbents derived from coal dust is proposed. Experimental results on the granulation model material, as well as an analysis of the population balance of the sintering process on the basis of the phenomenon of destruction of particles on impact are submitted. As a binder material for aglomeration was 2 -% solution of the polymer (hydroxypropyl methylcellulose (HPMC) Pharmacoat), which was pre-selected for the experiment of the coal dust aglomeration. As the working material for the experiments aluminum oxide Al2O3 was used – similar material to the coal dust to the physical and mechanical characteristics. To confirm the theoretical values, which were obtained by the simulation, the test of uniaxial compression and destruction of agglomerates for the vessel wall was obtained. The deformation and breakage properties of agglomerates were measured by uniaxial compression test using a Texture Analyser® device. During this test single agglomerate is loaded between two steel punches and the force-displacement curve is measured. The stress was applied at a controlled axial deformation rate of 20 µm/s. To investigate the influence of the size on the mechanical behavior the agglomerates were separated into 3 fractions: 1.7-2.2; 2.3-2.7; 2.8-4.0 mm. The results, which are presented in the paper, will help create quality agglomerates for cleaning gas from contaminants and will improve the quality of this energy source. |
