Plant energy particle compression forming device and system and plant energy particle manufacturing technique

Abstract

The embodiment of the invention discloses a plant energy particle compression forming device and system and a plant energy particle manufacturing technique. The device comprises a screw propulsion rod, a compression cavity and a forming cavity, wherein the compression cavity is provided with a circular-truncated-cone-shaped inner wall and communicated with the forming cavity, the forming cavity is provided with one or more forming channels, the inner diameter of each forming channel is unchanged or changes in a continuous or gradient way from the end connected with the compression cavity to the other end, and the screw propulsion rod is arranged in the compression cavity and comprises a spindle and spiral blades surrounding the outer wall of the spindle. Plant energy particles produced by means of the plant energy particle compression forming device and system and the plant energy particle manufacturing technique are quite low in cost.

Description

technical field [0001] The invention relates to the field of bioenergy utilization, in particular to a particle forming device, system and production process for plant straw and other agricultural and forestry waste containing plant energy. Background technique [0002] Plant energy refers to the energy that is converted and stored in plants by receiving sunlight during their growth, and can be released through combustion (such as the heat energy released by burning plant stalks). [0003] Plants absorb CO2 through photosynthesis during the growth process. Although CO2 is released during combustion, compared with the CO2 absorbed during the growth process, the overall CO2 release to the atmosphere is negative. Therefore, plant energy is a renewable and clean energy source, and plant energy is used as energy. , can effectively reduce CO2 in the atmosphere and solve the problem of global warming. [0004] However, in view of the low energy density of plant energy, substances ...

AI Technical Summary

Problems solved by technology

[0004] However, in view of the low energy density of plant energy, substances containing plant energy (hereinafter referred to as plant energy substances) such as plant straw, etc., have higher usage and transportation costs than fossil energy substances such as coal, oil, and natural gas. They are also unwilling to use plant energy substances instead of fossil energy substances to obtain energy, and fossil energy substances such as coal, the CO2 produced by combustion will aggravate the problem of global warming

[0005] In order to increase the energy density of plant energy substances, in order to replace non-renewable energy sources such as coal, and to solve the problem of environmental pollution, the existing method is to use compression molding equipment to extrude plant energy substances to form higher density plant energy particles. However, due to the current Plant energy granule forming equipment and methods have high energy consumption, high waste, and high equipment failure rate, resulting in high cost of plant energy granules after forming, far higher than the cost of digging coal, and the energy density of the final formed plant energy granules is not high, so at present, plant energy cannot compete with coal and other fossil energy materials in the market
