Biomass fuel conveying deivce

Abstract

The invention relates to a biomass fuel conveying deivce, in particular to a conveying deivce of powder biomass fuels. The biomass fuel conveying deivce comprises a conveying belt, a shuffling funnel, a feed hopper, a fan and a motor and is characterized by further comprising a floating dust pipe, a speed regulation plate, a conveying pipe and a material outlet. A chain speed reducer is arranged at one end of the conveying belt, the shuffling funnel is fixedly arranged above the conveying belt, and a side port, an upper port and a lower port are respectively arranged on the feed hopper. The conveying belt guides materials into the feed hopper form the side port, the upper port is connected with the floating dust pipe, and the lower port is connected with a fan port. Two ends of the floating dust pipe are connected with the upper port of the feed hopper and an air inlet of the fan respectively, and floating dust is sucked into an impeller of the fan under the negative pressure effect of the fan and is sent into a hearth through secondary conveying. A fan outlet and the speed regulation plate keep a certain distance, the conveying pipe enters a boiler through a boiler back door until to the middle of the hearth, and the conveying pipe is up with a certain inclination. A baffle is arranged at the front end of the material outlet so that fuels can be evenly jetted into the high temperature position in the boiler hearth.

Description

technical field [0001] The invention relates to a fuel conveying device, in particular to a fuel conveying device and method for biomass fuels such as straw, hay, bagasse, rice husk, sawdust and the like. Background technique [0002] Because biomass fuel is a by-product of agriculture and forestry production, it has large output and wide distribution, and is an environmentally friendly and clean renewable energy. Its high-efficiency utilization and conversion of higher-quality energy technology is the current development and utilization of renewable energy. An important direction with significant economic and environmental benefits. Specifically, the combustion and gasification of biomass materials are two important directions of development at present. Among them, based on the characteristics of long strips, uneven sizes, and easy interlacing of biomass fuels, how to provide an easy-to-manipulate, continuous Stable raw material conveying devices and methods have always be...

AI Technical Summary

Problems solved by technology

The above equipment has a complex structure and is suitable for long strip biomass fuel delivery devices

[0004] Biomass fuel powder with high crushing strength has low density, and it is more difficult to transport in the process of further combustion or gasification and reuse, and it is impossible to quickly transport the powdered fuel into the combustion device

If the feeding control is unstable, the problem of insufficient combustion is likely to occur, which will affect the efficiency

In the prior art, there is no powdery biomass fuel delivery device that is efficient, simple in structure, easy to operate, and conducive to full combustion. Therefore, there is a powdery biomass fuel delivery device with reasonable design, simple structure, high efficiency, and continuous stability. Conveying device, especially critical for biomass fuel combustion, gasification and reuse technology
