The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of multilayer fluidization solid continuous distillation tower, the tower body 16 that comprises a rectangle, the inside of tower body is the distillation chamber, the mixed vapour outlet 1 of exhaust steam and ethanol steam is arranged at the top of tower body, the upper portion side wall of tower body is shaped on charging aperture 15, sidewall in the tower body bottom is shaped on superheated steam import 10, and the bottom of tower body is shaped on the outlet 11 of material slag and rinse liquid outlet 12, and these mixed vapour outlets, charging aperture, superheated steam import, the outlet of material slag and waste liquid outlet all are connected with the distillation chamber.
Innovative point of the present invention is: interleaved is installed one group of gas distribution grid 6 adjustable with horizontal plane angle on the tower body inwall between charging aperture and the outlet of material slag, angle between each gas distribution grid and the horizontal plane is all adjustable, its scope is 0～60 degree normally, and the specific design angle is determined according to the angle of repose of distilling material.The quantity of gas distribution grid is not limit, and can regulate according to the height of tower body and the characteristic of material.
Gas distribution grid is versions such as porous plate or blast cap formula distribution grid, all is shaped on one group of steam pore 8 on each gas distribution grid, and the perforate direction of this steam pore is vertical or is certain angle.The superheated steam of gas distribution grid lower floor can enter the goods fluid section 4 of gas distribution grid top by the steam pore, and the material on the gas distribution grid then can not enter next bed by the steam pore of gas distribution grid.
On the tower body of corresponding each gas distribution grid bottom side, a material blanking control device is installed all, this material blanking control device is blanking device 5 or blanking flow regulator 9, as shown in Figure 2, blanking device comprises fixed axis 17 and rotation discharge valve 18, this rotation discharge valve is installed on the fixed axis, fixed axis is installed on the tower body, and its height is equal with the vapor distribution plate bottom, and its rotating speed can be regulated; As shown in Figure 3, the blanking flow regulator comprises rotating shaft 19 and flow control board 20, flow control board is installed in the rotating shaft, rotating shaft is installed on the tower body that is positioned at gas distribution grid bottom side, its height is equal with the vapor distribution plate bottom, and the angle between flow control board and the tower body inwall can be regulated.Can control the flow of material by the angle of regulating blanking device rotating speed or blanking flow regulator, thereby control the thickness of feed layer on the gas distribution grid.
It is the goods fluid section above gas distribution grid, fermentate is in fluidized state under the effect of superheated steam drag force, the contact surface of fermentate and steam is brought in constant renewal in heat, matter transmittance process, particle is contacted with steam evenly, realize the exchange of the two caloic better, can reach the distilling effect of the ethanol content homogeneous of material in mutually on the same gas distribution grid substantially; Below gas distribution grid and the superjacent air space of the goods fluid section of following one deck be the district (balance cylinder) 7 that balances each other, vapor phase has the delay of certain hour in the balance cylinder, can reach a metastable state in the delay process.
At each gas distribution grid upper end a steam pulse cleanout (not shown) is set, regularly purges for the material that in discharge process, is difficult to fluidisation, purge the side direction active force that produces and to promote material to enter next operating room smoothly.
The outside chuck 2 of installing of tower body, chuck superheated steam import 13 and chuck superheated steam outlet 3 is arranged on this chuck, the inner superheated steam that feeds of chuck can prevent the steam condensation of wall place, and a small amount of condensate liquid that produces in the operating process can be discharged by the rinse liquid outlet 12 at the bottom of tower.Chuck outer wrap one deck solid heat-insulation layer 21 is to reduce the heat loss of tower body.
A screw feeder 14 is installed at the charging aperture place of tower body, and the screw rod of this screw feeder is cored screw, and cored screw inside can arrange electric heater unit or feed superheated steam, so that when advancing material it is carried out preheating, has improved distillation efficiency.
The operation principle of this multilayer fluidization solid continuous distillation tower is:
Superheated steam is entered by superheated steam import 10, and air inlet pipe all is communicated with external steam generating means (not shown), and superheated steam can contact with the fermentation materials particle equably by bottom gas distribution grid 6.The solid fermentation thing enters on the porous plate that top layer tilts at a certain angle through screw feeder, carries out mass-and heat-transfer with up steam, and steam such as the ethanol in the fermentate are by up entrainment with steam, makes that concentration of ethanol increases in the steam.Then, the fermentation material moves to following inclination porous plate, further carries out the caloic transmission, and volatile matters such as ethanol wherein are distilled out from solid content.By the caloic transmission in multilayer orifice plate superinverse streaming, finally make the ethanol content in expecting to be pickled with grains or in wine be down to floor level.Bled steam with higher ethanol concentration is discharged from device top mixed vapour outlet 1, be cooled to ethanolic solution through condenser, perhaps exhaust steam and ethanol steam are directly carried out next step distillation operation, or the part mixed air can be refluxed, to improve the concentration of alcohol of product; When discharging, adopt steam vavuum pump or air-introduced machine (not shown) that power is provided, to guarantee the continuity of still-process.
Material after the distillation is poor is discharged by material slag outlet 11, and discharger is spiral or star-like discharger (not shown), and this discharger has air-tightness; The waste liquid that the regular maintenance of this device is cleaned can be discharged by the outlet 11 of material slag and rinse liquid outlet 12.In order to produce needs, reach optimum production effect, the several structural parameters in the experimental provision can be regulated, such as the number of plies can superpose arbitrarily, the angle of gas distribution grid 6, the rotating speed of blanking device 5 or the angle of blanking flow regulator 9.This device is obturator, can also be applicable to the distillation of other volatile materials from solid material in negative pressure, normal pressure or direct draught operation.
