Abstract

The invention discloses a brown coal rotary drying water removing device and a brown coal rotary drying water removing method. The water removing device comprises a rotary drying main machine, a driving device, a jacket type material screw feeder, a gas-solid product separation box and a rotation connector, wherein the rotary drying main machine is provided with a feeding end and a discharging end, and the rotary drying main machine is set to move in the axial direction when thermal expansion happens; the driving device is used for driving the rotary drying main machine to rotate around a shaft; the jacket type material screw feeder is connected with the feeding end of the rotary drying main machine; The jacket type material screw feeder is set to move in the axial direction of the rotary drying main machine when thermal expansion happens; one end of the gas-solid product separation box is connected with the discharging end of the rotary drying main machine; the rotation connector is connected with the other end of the gas-solid product separation box. The brown coal rotary drying water removing device is simple in structure, good in safety, efficient in heat exchanging, capable of saving energy, large in single machine processing amount, complete in water recovery, good in adjustability and capable of being widely applied to drying of brown coal of various grades.

Description

technical field [0001] The invention relates to equipment for drying lignite in a steam rotary tube type, and a method for rotary drying and dehydration of lignite realized by the equipment. Background technique [0002] Since lignite is a low-rank coal with high volatile content, high moisture, high ash content, low calorific value, easy weathering and spontaneous combustion, the unit energy transportation cost is high when used directly, which is not conducive to long-distance transportation and storage, and lignite is directly burned When the thermal efficiency is low, and the greenhouse gas emission is large, it is difficult to develop and utilize on a large scale. Therefore, lignite needs to be dried, dehydrated and upgraded before use to reduce its water content, increase its carbon content, and thereby increase its calorific value, so as to achieve efficient and economical utilization of lignite resources. The basic principle of lignite drying and dehydration technol...
