Description
Technical field
The utility model relates to biomass fuel forming process equipment, the drying device of particularly a kind of biomass fuel forming processing use.
Background technology
Often there is certain moisture content in biomass fuel, is the requirement making it meet processing and forming, usually needs to carry out drying to biomass fuel, to make it have suitable humidity in molding process.
In existing biomass fuel forming technique, the drying equipment of use mainly contains thermal current duct type or vapours, thermal current leads directly to cylinder heated type drying device etc.Adopt vapours formula drying device, carry out drying, the restriction of its heated vapor character by passing into vapours in drying device, its heating-up temperature cannot more than 100 DEG C, and the temperature difference is lower, and heat utilization rate is low, and energy consumption is large; And in order to produce vapours, usually also need outfit boiler dedicated, its equipment cost is also higher.In addition, also dirt may be there is in thermal current through type drying device dry run quick-fried, also safe not.Adopt cylinder heated type drying device, biomass fuel is placed in the cylinder of rotation, arranges heater and heat outside cylinder, is realized the drying of biomass fuel by cylinder wall transferring heat.Its mode of being conducted heat by wall carries out drying, and heat transmission speed is slow, and the thermal efficiency is low, and energy consumption is large, and inequality of being heated, the humidity difference of raw material is comparatively large, and easily occurs caking phenomenon, and drying effect is not good, and dry run required time is long.
Utility model content
The utility model is intended to the defect overcoming above-mentioned existing drying device, provides that a kind of heat utilization rate is high, the thermal efficiency is high, drying effect preferably biomass fuel drying device.
Biomass fuel drying device described in the utility model, comprise tank body, the top of tank body and bottom are respectively feeding mouth and discharging opening, at feeding mouth and discharge outlet, hermatic door to be opened/closed is set respectively, be provided with the heat sink that polylith vertical direction is arranged at the middle part of tank body, between feeding mouth and discharging opening, form many material channels separated by heat sink; Be provided with cavity in each heat sink, cavity two ends and heat carrier enter to manage and go out pipe with heat carrier and be communicated with, and make heat carrier enter after pipe flows through each cavity to go out pipe to flow out from heat carrier through heat carrier; The top of tank body is also provided with blast pipe, and blast pipe connects vavuum pump.
Biomass fuel drying device described in the utility model, during work, opens feeding mouth hermatic door, adds in tank body by a certain amount of biomass fuel from feeding mouth, fall into the passage that in tank body, each heat sink is separated out, then cut out hermatic door; Heat carrier is entered pipe by heat carrier send into continuously in the cavity of each heat sink of tank interior, heat exchange is carried out by heat sink and the biomass fuel that is positioned at passage between each heat sink, biomass fuel is heated, makes biomass fuel water evaporates, by heated drying; The steam evaporated then is discharged by the blast pipe on tank body top, and blast pipe connects vavuum pump simultaneously, and exhaust is simultaneously to evacuate space in tank, make raw material in tank body dry under vacuum conditions, after certain hour drying, open discharging opening hermatic door, dried biomass fuel is discharged.
Biomass fuel drying device described in the utility model, the high-temperature heat carrier be heated by tank body in fin cavity of its biomass fuel carries out, and not only heating surface (area) (HS is large, and heat utilization rate is high.Meanwhile, it can select the heat carrier of the high-temperatures such as conduction oil, and during heat exchange, the temperature difference can be larger, and heat utilization rate is also higher.In addition, its heat medium and heated material are separated by heat sink, and also can avoid the generation that dirt is quick-fried, thus security performance is also better.In addition, in its dry run, vavuum pump is vacuumized tank interior space by blast pipe, and enable drying device remain dry under vacuum conditions, in its raw material, moisture content is more volatile, and drying effect is better, and drying time is short.Under same dried effect, its thermal energy consumption is less, and the feature of environmental protection is better.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the structural representation of biomass fuel drying device described in the utility model.
Detailed description of the invention
As shown in Figure 1, Figure 2, a kind of biomass fuel drying device, comprise tank body 1, feeding mouth 2 and discharging opening 3 is respectively at the top of tank body and bottom, at feeding mouth and discharge outlet, hermatic door 4 to be opened/closed is set respectively, be provided with the heat sink 5 that polylith vertical direction is arranged at the middle part of tank body, between feeding mouth and discharging opening, form many material channels separated by heat sink 6; Be provided with the cavity of liquid flow in each heat sink, cavity two ends and heat carrier enter pipe 7 and go out pipe 8 with heat carrier and be communicated with, and make heat carrier can enter after pipe flows through each cavity can go out pipe to flow out from heat carrier through heat carrier; The top of tank body is also provided with blast pipe 9, and blast pipe 9 connects vavuum pump 12.
Multiple heat sinks in described tank body can be evenly arranged in tank body in the radial direction.It can make to enter biomass fuel in tank body evenly be distributed in passage that each heat sink separates.The cavity that heat sink is arranged can be the pipeline be fixed on heat sink, and the arrival end of the cavity of each heat sink is communicated with jointly on feed liquor house steward, and heat carrier enters pipe and is communicated with feed liquor house steward.The port of export of the cavity of each heat sink is communicated with jointly on fluid house steward, and heat carrier goes out Guan Zeyu fluid house steward and connects.Feed liquor house steward and fluid house steward can be positioned at the top of heat sink all in the form of a ring.It is consistent that said structure makes to flow into heat carrier flow in each heat sink cavity by heat carrier inlet pipe, thus can biomass fuel in more uniform dry tank body; And the vavuum pump that blast pipe connects can vacuumize tank interior, by vavuum pump vacuumizing in tank body, can promote and accelerate the water evaporates of biomass fuel, improve drying efficiency.
Described drying device, also comprises liquid pump 10 and heat medium heater 11; Heat carrier enters pipe, heat carrier goes out pipe and is connected to form a closed circuit with liquid pump and heat medium heater by pipeline.During work, heat medium heater heats heat carrier, high-temperature heat carrier after heating is entered pipe by liquid pump conveying via heat carrier to be entered in the cavity of each heat sink in tank body, goes out pipe again get back in heat medium heater in cavity with biomass fuel heat exchange temperature after reducing through heat carrier.Described drying device, its heat carrier can recycle, and avoid the waste of heat carrier heat energy after heat exchange, save the consumption of the energy, the feature of environmental protection is better.
In order to improve drying efficiency and drying effect further, gases at high pressure can be set under tank body and be filled with pipe 13, gases at high pressure are filled with pipe 13 and are communicated with the high-pressure air source such as air compressor machine, nitrogen cylinder, be filled with pipe by the gases at high pressure in high-pressure air source from gases at high pressure and be filled with gases at high pressure to tank base, the biomass fuel in each passage can be made to stir, there is the phenomenon of class pseudo boiling, thus better, more fully can carry out drying to biomass fuel.
