Description

A kind of pyrolysis gasification system and its technique
Technical field
The present invention relates to biomass and Waste Disposal Technology field, specially a kind of pyrolysis gasification system and its technique.
Background technique
Biomass material, organic waste (rubbish) contain a certain amount of moisture content, inhale in pyrolytic gasification these moisture content early period Heat is received, after preheating and evaporation, i.e. dry materials process.In conventional pyrolytic gasification process, for biomass and organic waste Utilization is not added in the vapor of object (rubbish) pyrolytic gasification drying process early period discharge, directly diffuses or allow it to enter pyrolytic gasification In generated " synthesis gas ".Therefore the drying process heat absorption of material reacts category for pyrolytic gasification in conventional pyrolytic gasification process In invalid heat absorption, the thermal efficiency of pyrolytic gasification technical process is reduced;In addition vapor belongs to the nothing of pyrolytic gasification " synthesis gas " Ingredient is imitated, the active constituent content and calorific value of " synthesis gas " are reduced.
Summary of the invention
The vapor utilization rate generated when in order to solve existing pyrolytic gasification is low, the cost-effectively content and calorific value of synthesis gas Low problem, the present invention provides a kind of pyrolysis gasification systems, meanwhile, the present invention also provides corresponding pyrolytic gasification techniques.
Its technical solution is such that a kind of pyrolysis gasification system comprising the preheating and drying section sequentially arranged, pyrolysis Section, gasification section, which is characterized in that it further includes steam superheater and combustion furnace, the steam (vapor) outlet connection of the preheating and drying section The entrance of the steam superheater, gasification section described in the outlet of the steam superheater, the combustion furnace give the preheating Dryer section, pyrolysis section, gasification section, steam superheater provide heat, and the material outlet of the gasification section connects the combustion furnace, institute It states pyrolysis section and the gasification section is provided with syngas outlet.
A kind of pyrolytic gasification technique, which is characterized in that it includes the following steps:
(1) material enters preheating and drying section, is preheated and is dried under the action of the heat that combustion furnace provides, generates dried object Material and saturated steam;
(2) dried material enters pyrolysis section, and saturated steam enters steam superheater, in the effect for the heat that combustion furnace provides Under, pyrolytic reaction generation synthesis gas occurs for the dried material into pyrolysis section and charcoal, charcoal enter gasification section, into steam superheater Saturated steam become superheated steam, superheated steam is provided to gasification section;
(3) under the action of the heat that combustion furnace provides, gasification reaction occurs for charcoal and superheated steam into gasification section, generates conjunction At gas and carbon residue, carbon residue enters combustion furnace as fuel combustion, provides heat for each stage of pyrolytic gasification.
After applying the present invention, the vapor that preheating and drying section generates not instead of not directly release enters synthesis gas, will Its some or all of collection is used as gasifying medium to be used for gasification reaction using after heat, and the vapor as gasifying medium is not It is to be generated by additional other devices, and the vapor that spent material pyrolytic gasification preheating and drying section generates is effective to recycle The heat of material preheating and drying consumption, is used for gasification reaction, improves the material and capacity usage ratio of pyrolysis gasification system.
