Again as shown in figure 1, biological fuel gas caused by mixed suction gas-carbon cogeneration stove 5 sloughs bamboo charcoal particle by deduster 7
Thing, then be transported to by high temperature draught fan 8 in low NO 9, biological fuel gas and air blower 10 are defeated in low NO 9
The air sent is sufficiently mixed, and is fully burnt into boiler 11 afterwards, and the flue gas for generation of burning dries as Bamboo leftover
The thermal source of dry stove 2, by the proportioning of thermostatic control steam, to control the temperature of Bamboo leftover drying oven 2, temperature range exists
Between 150 degrees Celsius to 180 degrees Celsius, the tail gas after drying is discharged into chimney after the processing of deduster 13 by air-introduced machine 14
15；The steam of burning generation enters gas-distributing cylinder 12, and a part is used for bamboo charcoal finished product drying machine thermal source, and others are used as bamboo processing factory
Other use energy.
Continue as shown in figure 1, sloughing bamboo charcoal from bamboo charcoal particle caused by mixed suction gas-carbon cogeneration stove 5 and via deduster 7
Particulate matter is polished into bamboo carbon powder by flour mill 16, and the particle diameter of bamboo carbon powder is 60 to 100 mesh, subsequently into batch mixer 17.
Weight is added according to bamboo carbon powder, is quantitatively adding 3%~5% binding agent, adds 15%~30% hot water, hot water temperature's control
System stirs 45 minutes at 40~60 degrees Celsius.Subsequently into screw extruder 18, pass through roller press briquetting after being pressed further by batch mixing
Roasted charcoal is made in machine 19.Finally, roasted charcoal product, which enters in dryer 20, is dried to moisture below 5%, and dryer makes
The steam produced by the use of biological mass gas burnnig boiler 14 is as thermal source, and the temperature control of dryer is at 60 to 80 degrees Celsius.So as to obtain
The bamboo charcoal structure of shaping.
The high-efficiency environment friendly that the present embodiment realizes Bamboo leftover utilizes, and roasted charcoal, which is made, in the bamboo charcoal of production to produce
Raw huge economic value, biological fuel gas produces steam by low nitrogen burning can substitute the arcola of bamboo processing, environmental protection row
Put, boiler exhaust gas is further used for drying system energy, realizes that using energy source optimizes.By the process system of the present invention, build
If serving the energy, environment and the bamboo of ecological construction circulation Industry Model from Bamboo leftover utilization, make with low-carbon
Economy is the Recycling Economy System of core.
As the second embodiment of the present invention, propose that a kind of bamboo processing corresponding with Bamboo leftover multiplexer is surplus
Excess multiplexing method, including：
Step S1：After Bamboo leftover is broken into below 10cm fritter bamboo material, fritter bamboo material is dried into dryer
Do below fixed moisture；I.e. water content is below 20%.
Step S2：Product after drying is pyrolyzed by high angle belt conveyer conveyer into mixed suction gas-carbon cogeneration stove
Gasification reaction, generate biomass thermal combustion gas and bamboo charcoal particle；
Afterwards, fritter bamboo material is transported to feeding bin 3 and is transported to mixed suction gas charcoal by the belt material-feeding machine 4 of High angle
In coproduction stove 5, mixed suction gas-carbon cogeneration stove 5 includes eccentric fire grate 51, break doctor blade device 52, char zone 53, pyrolysis zone 54, entered
Expect sealing valve 55 and gas outlet 56, it is defeated by air blower 6 in char zone 53 and pyrolysis zone 54 respectively to mix suction gas-carbon cogeneration stove 5
Send oxidant, used in the present embodiment using air as oxidant, the usage amount of oxidant is according to char zone 53 and pyrolysis zone
54 temperature is adjusted respectively, and is automatically controlled by controller, or carries out remote control using server.Controller is also controlled
The reaction temperature of char zone 53 and pyrolysis zone 54 processed, wherein, the range of reaction temperature of pyrolysis zone 54 is taken the photograph at 400 degrees Celsius to 550
Between family name's degree, the range of reaction temperature of char zone 53 is between 750 degrees Celsius to 850 degrees Celsius.Mixed suction gas-carbon cogeneration stove 5
Bottom is provided with eccentric fire grate 51, and break doctor blade device 52 is provided with eccentric fire grate 51, can prevent bamboo charcoal coking, ensures
The uniformity of reaction.Feeding seal valve 55 is set on the charging aperture of mixed suction gas-carbon cogeneration stove 5 so that give birth to during the course of the reaction
Into biological fuel gas will not reveal, while controller control gas outlet 56 fuel gas temperature it is Celsius at 250 degrees Celsius to 300
Between degree, the generation of tar and waste water effectively prevent.
Step S3：Biomass thermal combustion gas is transported to after cyclone dust collectors separate bamboo charcoal particle by high temperature draught fan
The low NO of biological mass gas burnnig boiler；
Step S3 '：Biological fuel gas is burnt in biological mass gas burnnig boiler by reasonable wind distribution, and the steam of production is used respectively
In bamboo charcoal finished product drying and bamboo charcoal processing factory energy.
Biological fuel gas caused by mixed suction gas-carbon cogeneration stove 5 sloughs bamboo charcoal particle thing by deduster 7, then passes through high temperature
Air-introduced machine 8 is transported in low NO 9, and biological fuel gas and the air that air blower 10 conveys are abundant in low NO 9
Mixing, is fully burnt into boiler 11 afterwards, the thermal source of the flue gas of generation of burning as Bamboo leftover drying oven 2,
By the proportioning of thermostatic control steam, to control the temperature of Bamboo leftover drying oven 2, temperature range at 150 degrees Celsius extremely
Between 180 degrees Celsius, the tail gas after drying is discharged into chimney 15 after the processing of deduster 13 by air-introduced machine 14；Burning generation
Steam enter gas-distributing cylinder 12, a part is used for bamboo charcoal finished product drying machine thermal source, other to be used as bamboo processing factory other use energy.
Step S4：The bamboo charcoal particle that the deduster 7 of the bamboo charcoal particle sum of mixed suction gas-carbon cogeneration stove production is deviate from passes through gas
Power is transported in flour mill, is ground into bamboo carbon powder of the particle diameter in 60~100 mesh；
Step S4 '：Bamboo carbon powder in batch mixer, add a certain proportion of binding agent and hot water and be stirred batch mixing；
Step S4 "：Well mixed material enters roller briquetting machine after extruding mixing, bamboo is made by screw extruder
Charcoal finished product；
Step S4 " '：Bamboo charcoal finished product dries moisture in dryer.
Wherein, dryer uses in step S3 ' caused steam as thermal source.
Using above-mentioned technical proposal, due to Bamboo leftover being multiplexed, the utilization of Bamboo leftover is improved
Efficiency, meanwhile, biological fuel gas produces steam by low nitrogen burning can substitute the arcola of bamboo processing, environment protection emission, boiler
Tail gas is further used for drying system energy, realizes that using energy source optimizes, the bamboo charcoal of production further is made into barbecue type
Charcoal can produce huge economic value.
Embodiments of the present invention are explained in detail above in association with accompanying drawing, but the invention is not restricted to described implementation
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen within protection scope of the present invention.
