Biomass micro-positive-pressure pneumatic transmission system

Abstract

The invention discloses a biomass micro-positive-pressure pneumatic transmission system which comprises a feeding system, a fan, a conveying pipeline system, a discharging system, a tail gas treatment system and an automatic control system, wherein the feeding system comprises a quantitative feeding device, a collecting device, a positive-pressure air sealing device, an accelerator, an air guide pipe and a return air treatment pipeline; the conveying pipeline system comprises a straight pipeline, a connecting flange and a plurality of quick-operating doors distributed on the pipeline as well as a transparent observation window. The biomass micro-positive-pressure pneumatic transmission system has the advantages that smooth feeding with higher concentration ratio can be achieved, the power consumption is low, the service life of the air sealing device is prolonged, the applicability and the pipeline durability of the conveying system are improved, the convenience is provided for pipeline smoothening and repairing, the environmental pollution can be avoided, and the automation level is high.

Description

technical field [0001] The invention relates to a pneumatic conveying system in the mechanical field. The system is particularly suitable for conveying biomass and bulk and powder materials with low bulk density, specifically, a biomass micro positive pressure pneumatic conveying system. Background technique [0002] For a long period of time, for the handling of biomass bulk and powder materials with low bulk density, it is mostly carried out manually on a small scale, and mechanically assists on a large scale. Generally, woven bags are used for packaging, forklift loading and unloading, and transportation vehicles. way. This way of handling has high work intensity, harsh working environment, low work efficiency, and requires a lot of manpower and material resources. With the continuous expansion of the production capacity of enterprises in recent years, this handling method obviously cannot meet the needs of large-scale production. [0003] The conveying method of auger ...

AI Technical Summary

Problems solved by technology

In the husking process of rice processing, blowing the rice husks to the rice husk temporary storage bin through airflow is actually an application of micro positive pressure pneumatic conveying, but there are also problems such as low conveying concentration (0.5-2) and high energy consumption per unit conveying volume, because of this The transportation distance is very short in the environment, and the transportation is not the main task of the process, so there are not many studies on related issues, and no improvement methods have been published.
