Description
Technical field
Upgrading processing and recovery energy technical field the invention belongs to renewable biomass forest products discarded object, are specially
A kind of converting Processes and apparatus that three-phase recycling is carried out to forest products discarded object.
Background technology
With the increasingly consumption of fossil feedstock, fossil class carbon source for the survival of mankind is faced with the awkward situation of exhaustion, at the same time
Since the main application method of this kind of fossil-carbon energy is all directly to burn, cause atmosphere pollution to aggravate, greenhouse effects by
Year is obvious so that the ecological environment of the earth also runs down.Therefore, discarded renewable carbon resource is developed, is had suitable
Social value and economic benefit.
In various renewable carbon resources, forest products discarded object has the characteristics that species is more, distribution is wide, yield is big, renewable,
And due to rich in carbon, it is considered to be prepare the important carbon raw material of novel energy and chemicals, but forest products discarded object is also deposited
Energy density is low, quantum of output is by seasonal effect is obvious, moisture-sensitive is rotted, it is big to store difficulty, a wide range of collects and long-distance fortune
The defects of defeated of high cost, so, the utilization means in traditional method to these forest products discarded objects are mainly directly burnt, general
Its chemical energy is converted into thermal energy enforcement of going forward side by side and uses, and this Application way energy transformation ratio is low, the thermal efficiency of thermal energy after conversion
It is low, more pollutant can be produced, and be not easy to focus on.
Also there are some producers to use the pyrolytic technique in thermochemical study technology that these forest products waste materials are carried out heat chemistry to turn
Change to submit the utilization rate and utilization ratio of forest products discarded object.Pyrolysis is often called cracking again, it refers in hot conditions
Under, macromolecular (hemicellulose, cellulose and lignin etc.) organic matter contained in biomass is cut off using thermal energy, makes to divide greatly
Sub- substance decomposition is carbon containing less, the relatively small organic matter of molecular weight thermochemical study process.But heat of the prior art
Solution technology is all realized simply by the pyrolysis oven of single structure, and there is no either only a small amount of pretreatment operation, production is set
Standby configuration and technological requirement are higher, and whole pyrolytic process be also easy to occur pyrolysis not exclusively, the pyrolysis cycle is long, was pyrolyzed
The problem of side reaction is more in journey, cause Related product the problem of excessive impurity content, quality decline occur, to heavy industrialization
Production brings larger obstruction.
The content of the invention
Technical problem solved by the invention is to provide a kind of to the converting of forest products discarded object progress three-phase recycling
