The steam spraying device of the biomass gasification furnace is mounted in a low-suction type gasification furnace, is used for injecting water steam in straw combustion and gasification processes, and is provided with a temperature control device, thus the purpose of spraying certain amount of steam while setting the temperature can be achieved, the operation is convenient and simple, and the steam spraying device is very suitable to be used in operation of straw gasification furnaces.
Description
Technical field
The present invention relates to a kind of biomass gasifying furnace and spray into steam unit.
Background technology
Every cubic metre of calorific value of the inflammable gas of corn straw is 5327.7KJ/M
3, the fuel gases calorific value behind the lower suction type vapourizing furnace is 4808.8KJ/M
3, other content such as following table:
People find in using the straw fuel gas process, straw fuel gas in the cooking of cooking, heat up water, work limitation rate such as wall hanging stove heating is very slow because its calorific value is low, the time spent will be grown, thereby how improving the straw fuel gas calorific value is a current problem that needs to be resolved hurrily.
It is following to analyze main four gasifications of stalk gasifier:
Drying process: biomass under the effect of heat, are separated out surface-moisture after getting into vapourizing furnace.In the time of 200～300 ℃, be main drying stage.
Pyrolytic reaction: when temperature is elevated to more than 300 ℃, begin to carry out thermal response.In the time of 300～400 ℃, biomass just can discharge the volatiles about 70%, just can discharge about 30% volatile matter and coal will arrive 800 ℃.Pyrolytic reaction is separated out fugitive constituent and is mainly comprised water vapour, hydrogen, carbon monoxide, methane, tar and other compound.
Oxidizing reaction: the air of pyrolytic residue charcoal and introducing reacts, and discharges a large amount of heat simultaneously with biological support drying, pyrolysis and follow-up reduction reaction, and temperature can reach 1000～1200 ℃.
Reduction process: reduction process does not have oxygen to exist, and charcoal reacts in products of combustion in the zone of oxidation and water vapour and the reducing zone, generates hydrogen and carbon monoxide etc.These gases and fugitive constituent have been formed " hydrocarbon inflammable gas ", have accomplished the conversion process of solid biomass to geseous fuel.
Stalk is in lower suction type vapourizing furnace internal combustion; If in reduction process, increase the content value of water vapour, the C (charcoal) in water vapour and the reducing zone is more fully reacted, generate hydrogen and carbon monoxide; Be the hydrocarbon polymer inflammable gas, fuel gases calorific value can reach 17-21MJ/M
3, so just can improve the straw fuel gas calorific value.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art; Provide a kind of biomass gasifying furnace to spray into steam unit, it is installed in the lower suction type vapourizing furnace, in the straw burning gasification, sprays into a kind of device of water vapour; Be provided with temperature control unit; When can be implemented in the temperature of setting, spray into certain quantity of steam, easy to operate simple, be useful for manipulating very much of stalk gasifier.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of biomass gasifying furnace and spray into steam unit; Said device comprise hanging scaffold, down hanging scaffold, steam-pipe and and the vapor-nozzle that is connected of steam-pipe, last hanging scaffold and following hanging scaffold equal and opposite in direction, structure are identical, are circular discs; Evenly be provided with blanking hole on the circular discs; Following hanging scaffold is fixed installation, and last hanging scaffold connects a swing handle freely rotates hanging scaffold in 36 degree scopes, and the top of the bottom surface of last hanging scaffold, following hanging scaffold is equipped with a plurality of vapor-nozzles and temperature probe.
Last hanging scaffold is connected with the recirculated cooling water pipeline with following hanging scaffold.
The said steam unit that sprays into is installed on the reducing zone in the biomass gasifying furnace, and vapor-nozzle is located at down hanging scaffold below and the interior high-temp combustion thing intermediary locus of biomass gasifying furnace.
The present invention is installed in the lower suction type vapourizing furnace, in the straw burning gasification, sprays into water vapour, is provided with temperature probe, and is easy to operate simple when can be implemented in the temperature of setting, spray into certain quantity of steam, is applicable to manipulating very much of stalk gasifier.
The invention enables stalk in lower suction type vapourizing furnace internal combustion; In reduction process, increase the content value of water vapour, the C (charcoal) in water vapour and the reducing zone is more fully reacted, generate hydrogen and carbon monoxide; Be the hydrocarbon polymer inflammable gas, fuel gases calorific value can reach 17-21MJ/M
3, improved the straw fuel gas calorific value.
The present invention is through rotate going up hanging scaffold, to regulate the blanking hole position on blanking hole and the play hanging scaffold on the hanging scaffold, realizes in biomass gasifying furnace, stopping material, feed, the deashing of hanging scaffold under reaching.
