Drying and dehydrating system for preparing biomass fuel from crop straws

Abstract

The invention relates to a drying and dehydrating system for preparing biomass fuel from crop straws. The system comprises a straight plate, a feeding device, a transmission drying device and a discharging device, the feeding device is mounted on the outer wall of the left end of the straight plate, the discharging device is mounted on the outer wall of the right end of the straight plate, and thetransmission drying device is mounted in the straight plate. According to the system, the following problems during drying and dehydration of crop straws can be solved: 1, at present, domestic crop straws are basically dried and dehydrated on an open-air platform, the straws are dehydrated and aired in an airing mode, the airing effect and the airing time of the straws can be affected by changesof weather, and the straws can be damped again in the airing process; and 2, an existing crop straw drying and dewatering device basically conducts dewatering operation on straws through rotation of adewatering barrel, the dewatering barrel rotates generally to only spin-dry moisture on the outer surface of the straws, and the moisture in the straws is difficult to spin out directly.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a drying and dehydration system for producing biomass fuel from crop stalks. Background technique [0002] The research and development of biomass fuel technology has become a major global hotspot, and has attracted the attention of governments and scientists around the world. It has a very promising future in solving energy problems. Many countries have formulated corresponding technology development and research plans for The utilization of domestic resources has proposed more new methods. However, many foreign bioenergy technologies and devices have reached the level of commercial application. At the same time, compared with other biomass energy technology applications, biomass pellet fuel technology It is the easiest to achieve large-scale production and use, and it is also more able to reduce the consumption of non-renewable resources and provide a direction ...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the current drying and dehydration of crop straws. First, the drying and dehydration of domestic crop straws are basically placed on the open-air platform, and the straws are dehydrated and dried by drying. This method will vary according to the weather. Changes will affect its drying effect and drying time, and it may be damp again during drying; 2. The existing crop straw drying and dehydrating device basically dehydrates the straw through the rotation of the dehydration bucket, and the rotation of the dehydration bucket generally only It can dry the moisture on the outer surface of the straw, but it is difficult to directly shake off the moisture inside the straw. Therefore, it usually needs to be dried after dehydration, and it takes a long time to dry the straw, which solves the waste of straw resources and provides sustainable Sustained development has made a great contribution
