The biological material that above-mentioned application is used, typically from the waste recovery of some industries, including timber and the extraction of agricultural product and conversion.Biomass material under initial condition contains higher moisture and bigger particle volume, is difficult to be directly used in the biomass application in modern times.
In some cases, use the mobile grate in old-fashioned and traditional method, such as main equipment or fluidization, biomass material side-product can be made to be used directly to heating.But this way can cause serious energy loss, and, the fume emission of high concentration needs supporting more complicated gas extraction system.
Limiting to release these, biomass material processes and arises at the historic moment.It is 10% or less that biomass material is dried to water content, and corresponding different application is ground to several microns of granules to several mm sizes.
Generally, biomass processes industry relies on grinder and rotary drier combination performs above-mentioned processing procedure.This processing mode is problematic, because the burner that drying system is to rely on some dried biomass of burning comes to biomass material heating, therefore, emission control systems has become a necessary additional configurations.Additionally, cannot create with avoiding, rotary drier and necessary aid system are installed, and build large-sized workshop to accommodate the cost of whole system.
In general, all types of drying machines (including rotary drier, flash tube dryer etc.) need in heating process: 1) utilize the dried biomass finished product of part as burner fuel, heat biomass material；2) emission control systems processes flue gas；With 3) certain capital input, this is not economic capital input for middle-size and small-size factory.
Furthermore, existing biomass are dried and show instability in processing procedure with grinding technique, and energy efficiency is low and/or water separation capability is limited.Particularly, these technology often discharge steam and hot-air from hothouse, and heat energy scatters and disappears the most in this form and slatterns.
Saturated air in some technology circulation and stress hothouses, actually limits their water separation capability to biomass material.When the air of circulation and stress reaches moisture-saturated, more moisture just cannot be absorbed.These technology operate at low temperatures, and the condensed water of generation causes the biomass of thickness to accumulate in hothouse and monomer cyclone separator.
So needing an effective method and system to process biomass material.
Summary of the invention

Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by with reference to detailed description below, these and other features of the invention, advantage will become better understood, wherein:
Fig. 1 is the structural representation of biomass material processing system first embodiment of the present invention；
Fig. 2 is the structural representation of biomass material processing system the second embodiment of the present invention；
Fig. 3 is the structural representation of preheating unit in Fig. 2.
Detailed description of the invention
It is described in detail below in conjunction with 1 to 3 pair, accompanying drawing biomass material of the present invention processing system and method.
Fig. 1 show biomass material processing system first embodiment of the present invention.Biomass material is stored in feed hopper 2, by conveyer 1(such as conveying worm) enter biomass material processing system.Biomass material is discharged in conveyer 1 by the star-shaped feeding machine 18 bottom feed hopper 2, and then by biomass, the especially biomass of bulk are delivered to bottom main chamber 3.
The latter half of main chamber 3 is mounted with that a vertical axis, blade 5 and chain 6 are connected on this axle.Such as one the Composite Skin V belt translation (B) of energy transmission system 4(utilizing belt pulley to constitute adds a motor (M)), main shaft can be with the high speed rotating higher than 1200rpm and drive chain 6 and blade 5 to reach required speed, under the abrasive action of chain 6 and the dissection of blade 5, bulk biomass material size significantly reduces.Use variable-speed motor just can realize the control to speed.
When biomass material falls the bottom of main chamber 3, repeatedly become tiny biological particles with blade 5 grinding and cutting by chain 6.The air-flow produced due to blade 5 promotes, the suction that aerator 7 produces bottom main chamber 3, and the negative pressure that air exhauster 11 produces, and these tiny biological particles move up.When biomass material is ground into little granule, hydrone therein can be discharged in air, thus reduces the water content of biomass.Part superficial water is detached system with atomised form by air exhauster 11.
An inner cylinder 16 is had in main chamber 3, coaxial with outer cylinder 17 and concentrate on top, main chamber, form a ring-type sealing coat.
When biological particles and hydrone rise bottom main chamber 3, promoted by the tangential air of aerator 7 input, carry out spiral circular motion.
Flange 21 connects top, main chamber, bottom, main chamber.Flange 21 is annular flange, and hole, linking main chamber 3 and inner cylinder 16 are opened in center, allows biological particles arrive inner cylinder 16 by flange 21 bottom main chamber；Equally, several little perforation connection main chamber 3 and outer cylinder 17 is had to allow hydrone pass through from bottom and to arrive region between outer cylinder 17 and inner cylinder 16 at flange periphery.By the ring-type sealing coat in main chamber 3, flange 21 guides hydrone granule stream into outer cylinder 17 and air exhauster 11, and tiny biological particles stream is guided into inner cylinder 16.
Above-mentioned main chamber 3 is cylindrical structure, but all hollow rotary bodies, as hollow hexagonal column structure is also suitable.
The shape of main chamber 3 can utilize the moisture in centrifugal force separate biological particles.Owing to the density of particle water is higher than dry/fine biological particles, and the active force of centrifugal force is directly proportional to the weight of granule, the center of the closer main chamber of speed ratio particle water 3 of dry/fine biological particles, and the rotation of particle water is then closer to the sidewall of main chamber 3.Hydrone granule stream is isolated by the ring-type sealing coat in main chamber 3 with biological particles stream, and hydrone granule stream discharges main chamber 3 by air exhauster 11, and biological particles stream will be pumped to inner cylinder 16.
When biological particles arrives the internal flange 21 in main chamber 3, they can be by the porch of the central through hole suction inner cylinder 16 of flange 21.Because biological particles with identical angular velocity around the center of circle rotate, centrifugal force and on revolve air effect under, act on the centrifugal force on the biological particles within inner cylinder 16 less than acting on the centrifugal force around inner cylinder 16 wall.Therefore, heavier biological particles trends towards hitting inner cylinder 16 inwall, by the bottom of flange 21 central through hole landing to main chamber 3, above-mentioned grinding is again carried out at that, cutting and dehydrating operations, until they are enough light, can be pushed into the top of inner cylinder 16 by conveying air.
At inner cylinder 16 top equipped with a screening washer 8.Screening washer 8 can be classified according to biological particles volume size: the most sufficiently small granule just can pass through screening washer 8, and remaining granule can send back to reprocess bottom main chamber 3 by the central through hole of flange 21.
Therefore, the fewest by inner cylinder 16 and the positive action of screening washer 8, only water content, and the sufficiently small biological particles of size sends main chamber 3 under the effect of air-flow.After leaving main chamber, conveying air stream and biological particles are transported to multi-cyclone 9.Inside, biological particles is separated with conveying air and is collected together, and discharges finally by the blocking valve 15 bottom cyclone separator 9.
The air themperature discharged in view of system can recycle by collecting the conveying air discharged from multi-cyclone 9 higher than ambient temperature, energy.In order to realize this purpose, aerator 7 can be used to bleed from multi-cyclone 9 top, conveying air is sent back to bottom, main chamber 3.Meanwhile, the surrounding air (see surrounding air aerator 13) of preheating is added to compensate the air that air exhauster is externally discharged.
In main chamber 3, when water vapour arrival outer cylinder 17 top first exports, can be extracted out feeding heat exchanger 10 by air exhauster 11.Owing to the gas flow temperature discharged is higher than ambient temperature, by the heat energy of exchange air-out to the surrounding air compensated, the main energy loss of system is able to recycling.This mechanism is also prevented from introducing saturated air in main chamber 3, thereby assists in the water separation capability of the air of raising injected system.
Surrounding air is delivered in heat exchanger 10 by aerator 13, absorbs the heat energy that air-out/fog (from the air of aerator 11 conveying) transmits.Before make-up air after preheating and recovery air Mixed design main chamber 3, also will be through an electric heating tube 12, in order to control its temperature and humidity and all reach preset value.Alternatively, it is also possible to use heat pump to increase the temperature of make-up air.Additionally, feasible time, it can also inject in external heat source 20 to electric heating tube 12.Just action during the electric heating tube 12 only temperature in make-up air temperature is less than main chamber 3, in general, the air themperature entering bottom, main chamber 3 is about 50 to 70 DEG C, such as when 70 DEG C, for efficient moisture absorption.
Make-up air after heating and reclaim air mixing laggard enter main chamber 3.After make-up air after heating and recovery air mixing, in tangential direction downward angle enter main chamber 3, are easy to produce a vortex in bottom, main chamber 3.The temperature of the make-up air after heating and recovery air is higher, beneficially dry the and lock out operation of system.The controlled system of thermal current of entrance system controls, within guaranteeing that this intrasystem temperature is maintained at specific operation scope, between 50 DEG C to 70 DEG C.Owing to the temperature in main chamber 3 is maintained at below the boiling point of water, biomass are main in liquid phase state in dry run, i.e. drain from main chamber 3 to the second of outer cylinder 17 top the outlet with mist form.
It is internally formed a negative pressure during exhaust fan 11 action in main chamber 3, thus decreases the heat energy needed for allowing biological surface hydrone evaporate, help the moisture being released in biological particles.
For guaranteeing that system effective operation needs to design a set of control system.This control system is for controlling to enter the temperature of the recovery/make-up air in main chamber 3, and makes the operating pressure in main chamber need to maintain negative pressure state.
A temperature sensor can be filled between heat exchanger 10 and electric heating tube 12 and monitor the make-up air temperature in heat exchanger 10 exit position.Another temperature sensor can monitor the temperature in main chamber 3.When the temperature that make-up air sensor is measured is significantly lower than the temperature of main chamber's sensor, electric heating tube 12 can be activated, and otherwise, electric heating tube 12 remains off.
Pressure in main chamber 3 to be measured, can be directly connected on air exhauster 11 with a pressure transducer.If the hypertonia in main chamber 3, air exhauster 11 Accelerating running, until the pressure in main chamber 3 returns to its preset level.
When the water content of biomass is too high, as water content exceedes the 50% of weight, as the mud of sewage treatment plant, its water content reaches as high as 80%, and biomass are tacky.The biomass too high in order to process water content, on the basis of the biomass material processing system shown in Fig. 1, add a preheating unit 100, and connect both conveying mechanisms 300, form the second embodiment of biomass material processing system of the present invention, as shown in Figure 2.
Preheating unit 100 as shown in Figure 3, biomass, by being positioned at the hopper 104 at hothouse 108 top, enter predrying unit 100.It is positioned at the blocking valve 112 below hopper 104, by transducer drive, can control to enter the biomass flow of hothouse 108.When blocking valve 112 is opened, biomass fall on the conveyer belt in hothouse 108.A series of speed change conveyer 116a, 116b, 116c arrange in a series arrangement.Guide plate 120 is positioned on the inwall of hothouse 108, it is ensured that biomass fall on conveyer 116a, 116b and 116c rather than on they sides.Infrared heater 124, such as halogen heating element heater, is arranged on above defeated machine 116a, 116b and 116c, to biomass radiation heating, reduces biomass water content.The length of infrared heater 124 and quantity, and the selection of the transporting velocity of defeated machine 116a, 116b and 116c is premised on the moisture reducing biomass to greatest extent, i.e. depends on character and the water content of biomass.
By controlling the running of infrared heater 124, monitoring biomass and the temperature of hothouse 108, to guarantee that temperature will not be too high and damage conveyer 116a, 116b and 116c.
The air exhauster 128 that the steam produced in hothouse 108 or mist are contained in hothouse 108 top by one is extracted at air vent 138.Air exhauster 128 can be a vacuum exhaust blower, is used for setting up a vacuum environment, i.e. forms negative pressure in hothouse 108.Formation negative pressure at hothouse 108, it is possible to reduce the heat energy needed for biomass moisture separates.Its principle is when height above sea level is higher than sea level altitude, and under atmospheric pressure effect, the boiling point of water reduces.Therefore, the moisture evaporation rate quickening in negative pressure can make hothouse 108 is formed at hothouse 108.Furthermore, negative pressure is accelerated moisture and is drained from biomass；The air discharged from hothouse 108 forms an aqueous vapor transport passage, and the aqueous vapor that will be attached to biomass is discharged outside hothouse 108.
The outlet of vacuum blower 128 may be connected to an exchange cyclone 132, will be sent back in hothouse 108 before discharging air vent 138 by the biological particles of air-flow sucking-off hothouse 108.In hothouse 108, the air of sucking-off discharges from the air vent 138 of drying system 100, and described air vent 138 can be connected with the air inlet of air exhauster 11.
If there being more ground space may utilize, one long, and straight induction system can substitute for the intensive supply unit being interspersed being made up of as shown in Figure 3 speed change conveyer 116a, 116b and 116c.
The quantity of infrared heater 124, conveyer 116a, the length of the conveyer belt of 116b and 116c and transfer rate, depend on the state before biomass entrance drying system 100 and the state at outlet 142, and the processing system that the most above-mentioned combination Fig. 1 is illustrated requires the biomass state of input.
This invention system can be processed into dry fine powder biomass material, has recycled the heat energy that the overwhelming majority is taken away by discharge steam and hot-air simultaneously.
Biomass can derive from timber, such as waste material or the side-product of forest industry, or derives from other industry, such as agricultural and animal waste, or paper pulp, paper and sewage disposal mud.If necessary, or as the precautionary measures, biomass material can clip to several inches of sizes before entrance system.
Modern biotechnology matter apply in, the powdered biomass purposes of finished product widely, including general production wood pellet, wooden unit and bio-fuel；Powdered biomass can produce heat energy by using powder burner or pyrolytic process, it is also possible to is used for producing nanocrystal cellulose, methanation process etc..
Briefly, this system is rotated by motor band moving vane 5 and chain 6 provides mechanical energy to form one internal gas flow to biomass material, blade 5 simultaneously as inner fan.The airflow function formed by internal system, light biological particles is with air motion, and heavier biological particles drops back into blade 5 and dehydration/crushing process is continued in chain 6 position.Additionally, contained heat energy recycles in system by heat exchange principle in the air of part discharge system, it is to avoid moisture is again introduced into system.Furthermore, optimize the water absorbing capacity of main chamber 3.
The design of gas extraction system meets the condition forming vacuum, i.e. produces in addition to a negative pressure, the air-flow of discharge running temperature in providing main chamber 3 in main chamber 3, also promotes moisture to evaporate, thus strengthen the water separation capability of system.
In general, processing procedure includes bottom biomass material being transported to system main chamber 3, is smashed by biomass material by the repeated action of blade 5 and chain 6；One xeothermic air-flow carrying out automatic heat-exchanger will tangentially enter system simultaneously；Under the influence of centrifugal force, hydrone, the biological particles of light biological particles and weight is separated one by one；Excessive biological particles is selected device to isolate by circular granular, we term it screening washer；Multi-cyclone 9 is used to efficiently separate biological particles and conveying air；Circulation and stress conveying air is re-fed into system；The thermal energy exchange taken away by 10 aerofluxuss of heat exchanger becomes make-up air in surrounding air；To make-up air post bake in electric heating tube 12, then make-up air is sent into system.
Biomass are changed into dry, fine powder by described method and system, contribute to promoting biomass and are converted into the application of the energy, reach to improve treatment effeciency, reduce gross investment, reduce and manage and the purpose of maintenance cost.
Described method and system synchronizes to carry out by grinding the operation with dried biomass raw material, obtains in an efficient manner and is dried/fine powder.This method and system, with dealing with biomass material, reach energy-conservation and high-efficiency dehydration purpose simultaneously.People can gradually find and appreciate the method and system advantage, because it can allow terminal use process biomass in a more economical way, eliminates the extras needed for thermal process, allows modern biotechnology matter use broader more economical.
