Flue gas drying equipment used for bagasse

Abstract

The invention discloses flue gas drying equipment used for bagasse. The equipment comprises a dehydration device, a material scraping device, a crushing device and a drying cabinet, wherein the dehydration device comprises a rolling unit and a suction unit arranged in the rolling unit, the rolling unit comprises a first pin roller and a second pin roller which are the same in size, a first gap allowing materials to be rolled therein exists between the first pin roller and the second pin roller, a first groove is formed in the outer surface of each pin roller and spirally surrounds the outer surface of a barrel of each pin roller, the distances between the adjacent rings of each groove are the same, and the adjacent rings of each groove are parallel; the material scraping device comprises atensioning mechanism and a material scraping line, the material scraping line is arranged on the tensioning mechanism and tensioned, the material scraping device is arranged below the first pin roller and the second pin roller, and the material scraping line is tightly attached to the lower surfaces of the first pin roller and the second pin roller; the crushing device is arranged below the dehydration device and comprises a funnel-shaped stock bin and a crusher; and the drying cabinet is arranged below the crushing device, and an air inlet used for leading flue gas or hot air in is further formed in the lower portion of the drying cabinet.

Description

technical field [0001] The invention relates to the technical field of bagasse drying, more specifically, the invention relates to a flue gas drying equipment for bagasse. Background technique [0002] Bagasse is the dregs left after sugarcane is pressed. It can be used for papermaking, board making, fertilizer or alcohol production, etc. Whether it is papermaking, board making, fertilizer making or storage, it needs to be dried in advance. [0003] The existing flue gas drying equipment for bagasse directly uses the flue gas discharged from the boiler to heat and dry the bagasse. Such drying equipment or drying methods do not pre-treat the bagasse, and the bagasse containing a large amount of water directly enters the In the drying equipment, the evaporation of water takes away a lot of heat, and drying the bagasse consumes a lot of flue gas, so the drying efficiency is not high, and the energy consumption is serious. [0004] There are also some factories that accumulate ...

[0003] The existing flue gas drying equipment for bagasse directly uses the flue gas discharged from the boiler to heat and dry the bagasse. Such drying equipment or drying methods do not pre-treat the bagasse, and the bagasse containing a large amount of water directly enters the In the drying equipment, the evaporation of water takes away a lot of heat, and drying the bagasse consumes a lot of flue gas, so the drying efficiency is not high, and the energy consumption is serious

[0004] There are also some factories that accumulate bagasse and dry it naturally before drying. Although it can save some costs, the efficiency of natural air drying is low and the drying is uneven. More importantly, the bagasse will ferment and change taste during the accumulation or drying process, reducing the availability of bagasse
