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 maize straw is 5327.7KJ/M
3, the fuel gases calorific value after down-draft type gasifying furnace is 4808.8KJ/M
3, other content is as following table:
People find in using the straw fuel gas process, straw fuel gas in the cooking of cooking, heat up water, the work limitation rate such as wall-hung boiler heating is very slow, because its calorific value is low, the used time will be grown, thereby how improving the straw fuel gas calorific value is a current problem urgently to be resolved hurrily.
Analyze main four gasifications of stalk gasifier as follows:
Drying process: after biomass enter vapourizing furnace, under the effect of heat, separate out surface-moisture.In the time of 200～300 ℃, it is main drying stage.
Pyrolytic reaction: start to carry out thermal response when temperature is elevated to more than 300 ℃.In the time of 300～400 ℃, biomass just can discharge the volatiles of 70% left and right, and coal will arrive 800 ℃, just can discharge about 30% volatile matter.Pyrolytic reaction is separated out fugitive constituent and is mainly comprised water vapour, hydrogen, carbon monoxide, methane, tar and other compound.
Oxidizing reaction: the residue charcoal of pyrolysis and the air of introducing react, and discharge a large amount of heat with biological support drying, pyrolysis and follow-up reduction reaction simultaneously, and temperature can reach 1000～1200 ℃.
Reduction process: reduction process does not have oxygen, and in the products of combustion in zone of oxidation and water vapour and reducing zone, charcoal reacts, and generates hydrogen and carbon monoxide etc.These gases and fugitive constituent have formed " hydrocarbon inflammable gas ", have completed the conversion process of solid biomass to geseous fuel.
Stalk is in the down-draft type gasifying furnace internal combustion, if increase the content value of water vapour in reduction process, the C (charcoal) in water vapour and 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 defect of prior art, provide a kind of biomass gasifying furnace to spray into steam unit, it is arranged in down-draft type gasifying furnace, spray into a kind of device of water vapour in the straw burning gasification, be provided with temperature control unit, can realize when the temperature of setting, spray into certain quantity of steam, easy to operate simple, the operation that is practically applicable to very much stalk gasifier is used.
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, described device comprise hanging scaffold, lower hanging scaffold, steam-pipe and and the vapor-nozzle that is connected of steam-pipe, upper hanging scaffold and lower hanging scaffold equal and opposite in direction, structure are identical, be circular discs, evenly be provided with blanking hole on circular discs, lower hanging scaffold is fixed installation, and upper hanging scaffold connects a swing handle freely rotates hanging scaffold in 36 degree scopes, and the bottom surface of upper hanging scaffold, the top of lower hanging scaffold are equipped with a plurality of vapor-nozzles and temperature probe.
Upper hanging scaffold and lower hanging scaffold are connected with the recirculated cooling water pipeline.
The described steam unit that sprays into is installed on the reducing zone in biomass gasifying furnace, and vapor-nozzle is located at the locus in the middle of the high-temp combustion thing in lower hanging scaffold below and biomass gasifying furnace.
The present invention is arranged in down-draft type gasifying furnace, in the straw burning gasification, sprays into water vapour, is provided with temperature probe, can realize when the temperature of setting, spray into certain quantity of steam, and easy to operate simple, the operation that is applicable to very much stalk gasifier is used.
The invention enables stalk in the down-draft type gasifying furnace internal combustion, increase the content value of water vapour in reduction process, the C (charcoal) in water vapour and 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 goes up hanging scaffold by rotation, to regulate blanking hole on upper hanging scaffold and the blanking hole position on lower hanging scaffold, realizes stopping material, feed in biomass gasifying furnace, and the deashing of lower hanging scaffold.
