Abstract

The invention discloses a solid fuel upgrading reaction device and a process thereof. The device consists of a solid fuel crushing system, a fluid-bed solid fuel upgrading device, a ventilator, a thermal smoke furnace, a dust remover and the like. The process adopts fluid bed technology, uses a gas drying medium with certain temperature for keeping brown coal fed into the fluid-bed solid fuel upgrading device in a full fluid state and drying the brown coal, and meanwhile finishes the delivery of the brown coal from a feeding hole to a discharge hole. The process has the characteristics of simple process, convenient operation, low energy consumption, flexible control for moisture content of the dried solid fuel and broad granularity adaptability, and can implement large-scale production without large-scale mechanical equipment.

Description

technical field [0001] The invention relates to a high-moisture solid material drying system and its technology, in particular to a solid fuel upgrading reaction device and its technology. Background technique [0002] my country is a country rich in lignite resources in the world. According to statistics, the country has proven lignite reserves of 130 billion tons, accounting for about 13% of the country's total coal reserves. Among the proven lignite reserves in China, they are mainly distributed in the northeastern region of Inner Mongolia, accounting for 75% of the national lignite reserves; the southwest region accounts for about 20%; and other regions account for about 5%. [0003] Lignite is a young coal that is easy to weather and spontaneously combust, has low calorific value and high water content. In my country, lignite is mainly used for direct combustion power generation. Due to the high moisture content in lignite, generally between 30% and 60%, if it is dire...
