Agricultural waste pyrolyzing furnace

Abstract

The invention relates to an agricultural waste pyrolyzing furnace, which includes: an inner cylinder, an outer cylinder, a grate, an outlet, an air outlet pipe, a furnace cover arranged on an inner cylinder upper port, as well as a feed inlet and an air inlet disposed on the furnace cover. Specifically, the bottom of the inner cylinder is connected to the outlet, and the grate is mounted between the inner cylinder and the outlet; a plurality of small vent holes are evenly distributed on a lateral side at the lower part of the inner cylinder; an annular airway is formed between the outer cylinder and the inner cylinder, and the air outlet pipe arranged on the outer cylinder, the airway, the small vent holes, and a breathable refractory layer together form an air extraction channel; and the furnace cover has a conical exterior shape, and a fabric assembly is disposed inside. The pyrolyzing furnace provided in the invention can convert agricultural waste into biological mixed gas or biomass carbon or a biological gas mixture, and the conversion efficiency is high, so that the furnace is suitable for the agricultural waste comprehensive conversion utilization devices needed by corresponding village (town) plant construction.

Description

Technical field [0001] The invention relates to a pyrolysis furnace, in particular to a continuous pyrolysis furnace for agricultural waste suitable for rural and rural levels. Background technique [0002] Agricultural waste includes crop stalks, tree trunks, branches, barks, roots, waste from wood processing plants, weeds, mushroom residue, furfural residue, vinegar lees, distiller's grains, pomace, manure of various animals, biogas residue, biogas slurry, etc. . Among them, crop stalks, forestry trunks, branches, barks, roots, woodware, wood processing plant waste, weeds, mushroom residue, furfural residue, vinegar lees and distiller's grains can all be used as pyrolysis raw materials, through pyrolysis gasification and carbonization technology Can be converted into, biomass charcoal, biological mixed gas. The comprehensive transformation and utilization of agricultural waste is of great significance to solve the energy crisis, reduce environmental pollution, and turn waste ...

AI Technical Summary

Problems solved by technology

[0003] The existing gasification pyrolysis furnace and dry distillation (carbonization) pyrolysis furnace have single functions and are not suitable for the comprehensive conversion and utilization of various agricultural wastes. For farmers, the structure is complicated and difficult to operate, the cost is high and the economic benefit is poor, and There is an urgent need for a pyrolysis furnace with simple structure, easy operation, low cost, good economic benefits, and suitable for many different types of agricultural waste
