Retort char, gas, oil, liquid, heat and fertilizer co-production system and process by biomass waste recycling

Abstract

The invention relates to a retort char, gas, oil, liquid, heat and fertilizer co-production system by biomass waste recycling; a liquid light hydrocarbon forced mixed gasifier is communicated with a combustion chamber of a biomass retort char producer, a gas outlet of the biomass retort char producer is connected to a gas-liquid-oil separation purifying device, products of the gas-liquid-oil separation purifying device treated by using a process are connected respectively to a biomass gas tank, a wood vinegar tank and a wood tar tank correspondingly, and an outlet of the wood tar tank discharges atomized tar through a heating atomizer and is then communicated with a combustion chamber of the biomass retort char producer through combustor II; the biomass gas tank is connected to combustor I through a control valve; a solid outlet of the biomass retort char producer discharges biochar powder. The system herein co-produces biomass char, gas, oil, liquid, heat and fertilizer by combining the liquid light hydrocarbon mixed gasifier with retorting, medium-caloric-value gas is supplied centrally, and the system is suitable for continuous operation, simple in structure, easy to operate, convenient to maintain, and good in safety and reliability.

Description

technical field [0001] The invention relates to a biomass waste recycling dry distillation carbon gas oil liquid heat fertilizer co-production system and process, which belongs to an environmental protection device for waste reuse. Background technique [0002] The technology of traditional carbonization kiln and coal and wood carbonization has long been mastered by people in our country, and the technology of biomass carbonization and the realization of coal, gas and oil co-production and centralized gas supply is an emerging technology that has emerged in my country in the past ten years. Widely used in rural new energy construction and other fields. The technology involves four systems of dry distillation, cooling, oil separation and purification, and transmission and distribution. Dry distillation system is a device for converting solid biomass into solid carbon, wood tar, wood vinegar and combustible gas. At present, only rice husk and sawdust powder materials can real...

AI Technical Summary

Problems solved by technology

At present, only rice husk and sawdust powder materials can realize continuous production in domestic biomass dry distillation equipment, and dry distillation equipment suitable for bulk raw materials are all intermittent production, the utilization rate of equipment is very low, and most of them use direct combustion of coal or wood, diesel oil Heating the retort not only has a low utilization rate of heat energy and wastes resources, but also emits a large amount of smoke and dust, pollutes the atmosphere, and causes environmental pollution
