A device for drying bagasse by furnace temperature

Abstract

A device for drying bagasse through furnace temperature is composed of a spiral bagasse supplier, a steam collector, a bagasse drying oven, a bagasse feeder, a plurality of steam discharging pipes and a bagasse pushing unit. The device for drying bagasse through furnace temperature is characterized in that a louver type exhaust hole of the steam collector communicates with a bagasse wall in the bagasse drying oven, and steam evaporated from bagasse passes through the louver type exhaust hole and enters the steam collector. The steam discharging pipes are arranged on the upper portion of the steam collector. A bagasse discharging opening of the steam collector is aligned with the spiral bagasse supplier, and bagasse taken out by steam is recovered. The inner side face of the bagasse drying oven is connected with a boiler hearth, the bagasse feeder is mounted on one side of the upper portion of the bagasse drying oven, and the bagasse pushing unit is mounted on the upper portion of the bagasse drying oven. The spiral bagasse supplier is mounted on the lower portion of the bagasse drying oven. The device has the advantages of being high in heat utilization efficiency, simple in structure, reliable in work, convenient to mount and the like.

Description

technical field [0001] The invention relates to a pretreatment process and equipment for boilers using biomass fuel, in particular to a device for drying bagasse by furnace temperature. Background technique [0002] Guangxi, as the largest province of sugarcane sugar production in the country, currently has 104 sugar factories. The main power equipment of the sugar factory is boilers, there are about 290 boilers, almost all of which use bagasse as fuel. Because the combustion technology of the bagasse furnace is backward, the water content of the bagasse is high, the combustion of the bagasse is incomplete, and the thermal efficiency of the boiler is low. The reason is mainly the following two problems: [0003] 1. Since the bagasse fibers are long and easily entangled with each other, the distribution in the furnace is not uniform, which directly causes the bagasse to burn unevenly; [0004] 2. The water content of bagasse is high, generally about 50%, which greatly affe...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the bagasse fibers are long and easily entangled with each other, the distribution in the furnace is not uniform, which directly causes the bagasse to burn unevenly;

[0004] 2. The water content of bagasse is high, generally about 50%, which greatly affects the temperature of the furnace, and is also the main reason for the incomplete combustion of bagasse

[0005] In order to solve the above problems, many people are looking for a new method of drying bagasse. Throughout the domestic sugarcane sugar enterprises, the method of drying bagasse is mainly to use the method of mechanically stirring the flue gas flow to dry. The drying effect of bagasse is not very good, and it has not been applied and promoted.
