Background technology
Now, because traditional resources such as oil, coal is day by day exhausted, people more and more tend to develop the new forms of energy of environmental protection, sustainable use, to satisfy the following energy and industrial production demand.Biomass resource is considered to the most promising renewable resource of 21 century.It comprises forestry living beings, agricultural wastes, water plant, energy-source plant, municipal refuse, organic wastewater and human and animal excreta etc.Agricultural ligno-cellulosic wherein is the biological material of storage capacity maximum in the world, also is a kind of abundant potential chemical raw material.An effective way of natural wood raw material potential value is fully excavated in the liquefaction of ligno-cellulosic materials just.By liquefaction, can make ligno-cellulosic materials be converted into alcohols, flammable oil or other has particular functional group's compound, thereby can be used as fuel or industrial chemicals uses.Ligno-cellulosic materials liquefaction, can be the mankind provides reproducible high-grade energy of environmental protection and industrial chemicals on the one hand, widens the field that utilizes of ligno-cellulosic materials, has improved the ligno-cellulosic materials utilization rate; On the other hand, can solve the handling problem of waste and old and poisonous woodwork, can reduce pollution, improve the ecological environment, therefore be with a wide range of applications.
The liquefaction of saying at present often refers to the Thermochemical Liquefaction method, be with raw material through pulverizing wait processing to handle after, under the high temperature catalyst effect pyrolysis or with other chemicals reaction generation imflammable gas and liquid.Nineteen eighty-three " science and technology today " of version once disclosed, and U.S. mine office utilizes a cover liquefying plant, and operating temperature is at 350～400 ℃, and a jar internal pressure is 4000Psig (about 280 atmospheric pressure), and can handle 1000 tons of dry substance average every day, can generate 1750 * 32
-2Gallon crude oil.Though this kind method can realize the liquefaction with ligno-cellulosic materials, reaction condition is too violent, produces dangerously, and energy consumption is big, and production cost is very expensive.People successively explored multiple gentle relatively liquifying method afterwards, and reaction temperature also greatly reduces.Studies show that, under the phenol existence condition, be catalyst with acid, can realize ligno-cellulosic materials liquefaction at 80～150 ℃; But the development of liquefaction device is backward relatively, lacks to realize the equipment that ligno-cellulosic materials liquefies by high efficiency, low cost, is an impediment to the suitability for industrialized production of ligno-cellulosic materials liquefaction.
Summary of the invention
The technical problem that the present invention requires to solve provides a kind of simple in structure, easy to operate, ligno-cellulosic materials liquefying plant that can solid lignocellulosic material be converted into liquid under normal pressure.
The present invention solves the problems of the technologies described above with following technical scheme:
In the pot body reaction vessel, heater and second thermometer are housed, stirring rod is inserted in the reaction vessel from the top of reaction vessel, the last termination motor of stirring rod, and there is paddle the lower end, and motor is electrically connected with speed adjusting device; In the periphery of stirring rod, the import and export of condenser, first thermometer and material are arranged; The lower port of condenser communicates with reaction vessel, and there is snakelike cooling water pipe inside, and the two ends of cooling water pipe tap into outlet pipe respectively; The thermometric end of first thermometer is in reaction vessel, and the thermometric end of second thermometer is lower than the heat conduction pasta in pot body, and the other end is electrically connected with thermostat.
The pot body places on the heat insulating mattress.
Ligno-cellulosic materials liquefying plant of the present invention, the liquefaction of lignocellulose material need not high pressure-temperature, and supplies consumption is few, and is simple in structure, is beneficial to popularization.
Description of drawings
Fig. 1 is the structural representation of ligno-cellulosic materials liquefying plant of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with Fig. 1:
In the pot body 2 reaction vessel 4, heater 3 and second thermometer 9 are housed, reaction vessel 4 is contained in the top of pot body 2 inner chambers, and heater 3 is arranged on the bottom of pot body cavity; The stirring rod 5 that is positioned at the reaction vessel axis is inserted reaction vessel from the top of reaction vessel, the last termination motor 6 of stirring rod, and there is paddle the lower end, and motor is electrically connected with speed adjusting device, can drive material during paddle work and rotate, and makes mixing of materials even.In the periphery of stirring rod, the import and export (not shown import and export) of the condenser 7, first thermometer 10 and the material turnover reaction vessel that distribute are arranged on circumference; The lower port of condenser 7 communicates with reaction vessel, and there is snakelike cooling water pipe inside, and the two ends of cooling water pipe 8 tap into outlet pipe respectively; Because condenser 7 communicates with reaction vessel, the material in the reaction vessel can be cooled off in condenser 7 and be liquefied being heated the volatile matter that is then generated, and flows back in the reaction vessel, thereby has significantly reduced the loss of the loss of material, especially medicine.
First thermometer, the 10 thermometric ends of temperature are in reaction vessel in the measured reaction container; The thermometric end of surveying second thermometer 9 of conduction oil temperature is lower than the interior heat conduction pasta of pot body, measures the real time temperature of conduction oil, and the other end is electrically connected with thermostat.
Pot body 4 can place on the heat insulating mattress 1, prevents high temperature burning to the ground supporter.
Reaction vessel 4, condenser 7, stirring rod 5, motor 6 and second thermometer 9 support the location by iron stand 13 and associated rod member.Fig. 1 illustrates: reaction vessel 4, condenser 7, motor 6 are respectively through rod member 12, rod member 14, rod member 15 clampings, location, and second thermometer 9 is simultaneously by rod member 14 location.
Before beginning liquefaction of lignocellulose material, inject the conduction oil that is equivalent to its volume 3/4 in the pot body; After reaction vessel 4 is submerged into the degree of depth that extremely suits in the interior conduction oil of pot body, rod member 12 by the band iron clamp is fixed on the iron stand 13, condenser pipe 7 is connected the back and is fixed on the iron stand 13 by the rod member 14 of being with iron clamp with reaction vessel, motor 6 with stirring rod extend into after stirring rod 5 is connected when reaching suitable height in the reaction vessel, be fixed on the iron stand 13 by rod member 15; Thermometer 9 is suspended on the rod member 14, and the thermometric end vertically submerges in the conduction oil.After finishing above-mentioned installation, ligno-cellulosic materials after pulverizing and the spice of fluxing are put into reaction vessel 4 through import and export, it is interior to the material surface that first thermometer 10 is stretched into reaction vessel 4; Connect heater and motor switch, open the condensed water valve, regulate temperature and rotating speed to reacting required technological parameter, heater 3 promptly begins to heat conduction oil, and reaction vessel 4 and material wherein are subjected to beginning to be heated and to liquefy behind the heat that conduction oil transmits; After institute adds material and liquefies fully, close down power supply, take off reaction vessel, draw off liquefaction products.
