Carbon matrix fertilizer production resource comprehensive utilization method based on updraft carbon gas co-production furnace

Abstract

The invention discloses a carbon matrix fertilizer production resource comprehensive utilization method based on an updraft carbon gas co-production furnace. The carbon matrix fertilizer production resource comprehensive utilization method comprises following steps: a, agriculture and forestry waste is crushed using a crusher, an obtained crushed material is introduced into a roller dryer for rawmaterial drying pretreatment; b, after drying, the material is introduced into the updraft carbon gas co-production furnace for pyrolysis gasification reaction to produce biomass charcoal and biomasscombustible gas; and c, the produced biomass charcoal is subjected to milling, obtained biomass charcoal powder is subjected to spraying treatment with pyroligneous liquor, an inorganic fertilizer anda binding agent are added into the biomass charcoal after spraying treatment so as to obtain a carbon matrix fertilizer, and the carbon matrix fertilizer is subjected to granulation so as to obtain carbon matrix fertilizer particles. The carbon matrix fertilizer production resource comprehensive utilization method is capable of realizing resource comprehensive utilization, and increasing energy utilization efficiency; and in addition, biomass combustion gas is subjected to low nitrogen combustion to produce steam, fire coal boilers can be replaced partially, environment protection discharge is realized, exhaust-heat boiler tail gas is further adopted in a drying system, and energy utilization optimization is realized.

Description

technical field [0001] The invention relates to the technical field of carbon-based fertilizer production, in particular to a method for comprehensive utilization of carbon-based fertilizer production resources based on an updraft carbon-gas cogeneration furnace. Background technique [0002] Today, my country's traditional extensive growth pattern of high consumption, high emissions, and low efficiency has not been fundamentally changed, resulting in low resource utilization and serious environmental pollution. [0003] The current resource and environmental situation is still very severe. It is necessary to vigorously develop the circular economy, and take various effective measures in accordance with the principle of "reduction, reuse, and recycling" to reduce resource consumption and environmental protection as much as possible. To achieve the maximum economic output and minimum waste discharge, realize the unification of economic, environmental and social benefits, and ...
