Carbonized heating supply system for rod production from forestry waste

Abstract

The invention discloses a carbonized heating supply system for a rod production from forestry waste. The carbonized heating supply system comprises a rod-making device consisting of a primary crushingmechanism, a fermentation yard, a feeding mechanism, an air drying mechanism, a screening mechanism and a hot pressing rod-making mechanism in sequence. An inner cavity of a roller of the air dryingmechanism is divided into three layers of inner and outer casing structures and is provided with positive and negative spiral feeding ribs to make wood chips flow back and forth and dry air; and a wood chip rod is formed by heating and extruding. The carbonized heating supply system also includes a plurality of cellar-type kiln bodies distributed in a matrix pattern, and a pre-burning heat-conducting tunnel is arranged between the two rows of kiln bodies. The combustible gas in a process of carbonization is affected by a boiler fan, and supplies heat to a boiler in sequence through a pre-combustion heat conduction undergroud tunnel, a total heat conduction underground tunnel, a diverter gate, and a heat supplying pipeline. Under the premise of low cost, relatively good insulation effect and airtight effect are achieved; energy consumption is greatly reduced; quality of charcoal is greatly improved; environmental pollution is eliminated, and at the same time, the instant utilization ofcarbonized gas is safely and conveniently realized; and the scale of the system is convenient for flexible adjustment.

Description

technical field [0001] The invention relates to a treatment of forestry waste. Background technique [0002] Forestry waste such as branches, bark, wood processing scraps, firewood, branch wood, curly bark, shavings, sawdust, etc. These wastes come from plants and are mainly composed of C, H, O, N, S, etc. It is the product of plant photosynthesis, and has the characteristics of renewability, sustainability, and abundant resources. [0003] However, the existing main treatment methods for these wastes are mechanical or manual crushing, and the crushed sawdust is used as fuel for direct combustion for heating, resulting in low combustion efficiency and serious smoke pollution. Contents of the invention [0004] The purpose of the present invention is to provide an efficient and convenient processing and utilization system for forestry waste, which can obtain clean and safe gasification energy in the process of producing high-quality biomass charcoal, with short carbon prod...
