Description
Technical field
The invention belongs to biomass energy application fields, specifically a kind of to convert fuel gas for agricultural crop straw
Method.
Background technique
It is well known that China is a large agricultural country, every annual meeting generates number with hundred million tons of various stalks, as wheat, stalk,
Peanut straw, potato stalk and sesame stalk etc..The past mankind can select to burn up stalk on the spot for convenience, although giving peasant
The time is saved, but brings very big pollution to environment and air, the life of the mankind is also affected therewith.In fact, agriculture
Crop material can carry out resource conversion, realize making full use of for stalk, and there are many kinds of the methods for handling stalk, for example chemical
Method, thermal spraying, cooking process etc., wherein chemical method is eliminated due to environmental protection and processing cost height；Thermal spraying need to be to processed
The pressure maintaining of stalk high cooking and spray material need for a long time cool down, cooking process due to taking more time boiling stalk,
Time used is greater than thermal spraying and causes energy consumption more, at high cost by stalk product is directly contributed.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of side converting agricultural crop straw to fuel gas proposed by the present invention
Method, the process employs a kind of stalk gasification stoves, hold straw by the upper combustion chamber and lower combustion chamber that are arranged in stalk gasification stove
Stalk, then controlled by the amount of air that control blower and the upward combustion chamber of ventilation duct are passed through stalk full combustion and
Burn incompletely, then the imflammable gas generated to burn incompletely are recycled, and processing cost is low, and treatment process is convenient
Fast, resource utilization is greatly improved.
The technical solution adopted by the present invention to solve the technical problems is: of the present invention a kind of by agricultural crop straw turn
