Solid fuel destructive distillation production process

Abstract

The invention aims to provide a solid fuel destructive distillation production process, which comprises the following steps: a, preparing materials: firstly, selecting solid biomass fuel, and preparing sufficient fuel for a curve hot blast stove and destructive distillation equipment according to a plan; b, starting system devices such as a DCS electric control cabinet system, instruments and meters, and opening all specified normally-open electric control valves; c, sealed feeding: starting feeding augers, feeding qualified fuel into a stock bin from a first feeding auger, then feeding the qualified fuel into a fuel filter by a second feeding auger, and pushing the qualified fuel into a barrel of a destructive distillation machine by a kick-out device according to a specified feeding amount, and meanwhile, starting a fuel filter heat exchange air output pipe fan and a carbon monoxide detector to supply a gasification medium to the curve hot blast stove; and d, sealed air supply: starting a rotary sealing element air pump pressure-stabilizing sealed operation system.

Description

technical field [0001] The invention relates to the field of dry distillation of solid fuel, in particular to a production process of dry distillation of solid fuel. Background technique [0002] Biomass is recognized as the most potential renewable energy in the world, and the form of biogas and biomass gas is widely used to supply gas to individuals or communities. Although the effect of biogas is good, due to the limited scope, it is difficult for biomass gas to reach the standard with low calorific value and tar content and gradually withdraw from the market. Using biomass dry distillation technology to produce dry distillation technology, dry distillation gas, tar, biomass charcoal, and wood vinegar are widely used in various fields of the national economy, which not only improves the quality of biomass gas, but also makes by-products provide very important raw materials for the chemical industry. Researchers have successively developed vertical biomass dry distillatio...

Problems solved by technology

[0003] In the existing solid fuel carbonization production process, when the solid biomass fuel enters the carbonization equipment, it is easy to contain a large amount of low-temperature air, which cannot be completely removed. Therefore, the low-temperature air entering the carbonization equipment will reduce the internal temperature of the carbonization equipment, causing the carbonization equipment Larger temperature fluctuations affect the carbonization effect of solid biomass fuels. On the other hand, the oxygen in the air will destroy the anaerobic environment in the carbonization equipment after entering the carbonization equipment, affecting the amount of carbon produced.
