Title:
DRYING APPARATUS FOR LIGNITE PARTICLES AND PULVERIZED COAL AFTER GRANULATION
Document Type and Number:
WIPO Patent Application WO/2014/107916
Kind Code:
A1
Abstract:
A drying apparatus for lignite particles and pulverized coal after granulation. The apparatus is a steam pressure autoclave. The steam pressure autoclave comprises a cylinder body. The cylinder body has arranged thereon ports for connection respectively to a pressure gauge and to a temperature gauge. An air inlet apparatus that is connected to a superheated steam conduit is provided at the bottom part of the cylinder body. A sewage outlet for discharging condensed water is also provided at the bottom part of the cylinder body. An exhaust opening for discharging sulfur dioxide and steam in the autoclave is provided either on the top part or the lateral part of the cylinder body. The drying apparatus ensures that the lignite particles are dried at optimal temperature and pressure to allow the lignite particles to be modified towards characteristics of bituminous coal, discharges an exhaust gas and the condensed water in a timely manner, reduces the amount of steam used, provides a reduced equipment costs, and allows the dried lignite particles to be provided with significantly reduced water content and minimized re-absorption and to be free from spontaneous combustion and weathering, and provides significantly increased calorific value per unit.
