Description
Technical field
The utility model relates to biomass energy technology field, refers to that a kind of stacking disc type biomass cure reactor continuously particularly.
Background technology
Along with the minimizing of the fossil energy reserves such as coal, oil, Sweet natural gas and the problem of environmental pollution that brings because of a large amount of uses of fossil energy are to the threat of survival and development of mankind, the development environmental-protective and regenerative energy comes into one's own further.Biomass are a kind of organism formed by photosynthesis, and it has huge, the widely distributed and feature such as carbon dioxide zero discharge after combustion gasification of reserves, is a kind of important renewable energy source.But the dispersion of biomass, High water cut, the high extensive gasification containing the feature limits of oxygen and difficulty fragmentation biomass utilize.
At present, existing biomass gasification technology comprises fixed bed gasification technology, fluidized-bed gasification technology and entrained flow bed gasification technology three class, first two is because gasification temperature is lower than 1000 DEG C, the tar contained in output raw gas also produces environment and equipment and pollutes while increase purified synthesis gas cost, and entrained flow bed gasification technology gasification core temperature is up to 1200 DEG C, tar etc. thoroughly can be resolved into gas, be the biomass gasification technology of environmental protection the most.But there is bottleneck in the development of biomass entrained flow bed gasification technology---how by certain means, the biomass of rich cellulose to be pulverized obtained qualified biomass powder.
Now, most employing technology of curing solves above-mentioned bottleneck, particularly, it is under normal pressure inert conditions, the biomass dehydration occurred at 200-300 DEG C of temperature and the reaction of part devolatilization, cure artifact matter because of fibrous texture and suffer that destruction greatly reduces grinding and processing cost, corresponding powder process of arranging in pairs or groups, wind powder are separated, dust-removing process can form a set of biomass pretreatment system being applicable to entrained flow gasification.Chinese patent CN103370401A discloses a kind of method and system for the torrefaction of lignocellulosic material, it is characterized in that the pallet top that biomass material is curing vertical stacking in reactor is rotated with coiling and contacts with the high-temperature gas spraying into reactor to realize drying, cure, biomass are fallen lower tray from the indentation, there of upper tray to realize the transfer of material between levels pallet.Following problem is there is in this reactor when reality uses:
Because the gas sprayed in reactor can only enter the space of more than this upper tray by the breach in upper tray, so gas cannot be uniformly distributed and the duration of contact of itself and biomass material very short, like this, gas also inabundant heat exchange just enters the space of more than this more top pallet from the breach more top pallet, thus seriously reduces the effect of curing.
Summary of the invention
The purpose of this utility model is the deficiency existed to solve above-mentioned background technology, and the stacking disc type biomass proposing a kind of Baking Effect good cure reactor continuously.
For achieving the above object, stacking disc type biomass designed by the utility model cure reactor continuously, this cures the reactor body that reactor comprises tubular structure, be arranged on the rotating shaft on described reactor body axis, be arranged on the driven unit be connected on described reactor body and with described rotating shaft, at least one block of column plate being arranged on the band sector notch in described reactor body, to be arranged in described rotating shaft and the material scraping plate of fitting with described column plate upper surface, output terminal is arranged in and cures medium input tube below described column plate, the described input terminus curing medium input tube runs through respectively and extend out to outside described reactor body, the card of column plate described in every block is respectively equipped with bubble holes, column plate described in every block with corresponding described in cure between medium input tube and be respectively equipped with the pallet that a piece is with sector notch, size and the position of the breach on described pallet and the breach on corresponding described column plate match, described pallet is at least provided with one with corresponding described in cure medium input tube the blast cap that is communicated with of output terminal, the air outlet of described blast cap is towards the described column plate of correspondence.By adding bubble holes on column plate, and add below column plate and the blast cap curing medium input tube and be communicated with, blast cap is fixed again with pallet, like this, bubble holes is passed by blast cap from the medium that cures curing the output of medium input tube, directly contact with biomass material on column plate and carry out heat exchange, and without the need to first by tiny sector notch, contact with biomass material on column plate again and carry out heat exchange, thus greatly increase the efficiency of heat exchange, and cure medium and can more uniformly contact with biomass material, and then make Baking Effect better; Simultaneously, because the medium that cures in this reactor is contacting with biomass material from bottom to top, and the medium that cures of the prior art top-downly to contact with biomass material, so the duration of contact of curing medium and biomass material in this reactor is longer, contact area is larger, thus the heat exchange carried out is more abundant, Baking Effect is better.
In such scheme, the position being positioned at described sector notch edge between described column plate and corresponding described pallet is provided with sealing plate, and described sealing plate, corresponding described pallet, corresponding described column plate and described reactor body surround blowing chamber jointly.Jointly blowing chamber is surrounded with pallet, column plate and reactor body by the sealing plate added, like this, be more conducive to curing medium successfully through bubble holes, accelerate the flowing of curing medium, thus further increasing the efficiency of heat exchange, improve Baking Effect; Meanwhile, the blowing chamber surrounded limits the flow range curing medium, cures medium like this and can not flow through sector notch, thus makes the up whereabouts can not disturbing biomass material of curing medium, and then improves the processing efficiency of biomass material.
In such scheme, described sealing plate is the bending plate that matches with described sector notch of bending angle or the assembled plate by two pieces of plate weldings.
In such scheme, described sealing plate upper end is fixedly connected with the two radius edge seal of the sector notch of corresponding described column plate, described sealing plate lower end is fixedly connected with the two radius edge seal of the sector notch of corresponding described pallet, the outward flange of described column plate is connected with the inner wall sealing of described reactor body, and the outward flange of described pallet is connected with the inner wall sealing of described reactor body.
