Abstract
The invention discloses a recycling technique and equipment of latent heat of liquefied fermented glutinour rice, which is characterized by the following: guiding liquefied fermented glutinour rice from pressure-retaining tank into flashing tank at negative pressure; making water in the liquefied fermented glutinour rice generate steam; connecting upper part of flashing tank and steam spraying vacuum pump; adsorbing secondary steam; blending with fresh steam.
Description
The Processes and apparatus that liquefied fermented glutinous rice latent heat of the present invention is recycled belongs to the Chemical Engineering and Technology field, relates to starch liquefacation, is a kind of production technique of improved liquefying starchiness raw material.
In production process with starchy material fermentative Production glucose, alcohol and citric acid, at first need liquefying starchiness raw material, the temperature of liquefaction needs saccharification is carried out in the liquefied fermented glutinous rice cooling again at 95-130 ℃ subsequently, or directly filter etc.Traditional production technique is liquefied fermented glutinous rice to be fed enter next step operation after air cooler is cooled to preset temperature, and liquefied fermented glutinous rice cooling institute liberated heat is not used by having slatterned in vain.
The Processes and apparatus that liquefied fermented glutinous rice latent heat of the present invention is recycled just provides the method that a kind of energy recovery utilizes, and reaches energy saving purposes.
The technology that liquefied fermented glutinous rice latent heat of the present invention is recycled realizes by following steps: (1) enters flash tank after liquefied fermented glutinous rice is drawn from the pressurize jar, flash tank is a negative-pressure operation, moisture content in the liquefied fermented glutinous rice produces secondary steam in this part vaporization, moisture content is vaporized required energy from liquefied fermented glutinous rice itself in the liquefied fermented glutinous rice, therefore the liquefied fermented glutinous rice temperature reduces, and has reached the purpose of liquefied fermented glutinous rice cooling; (2) flash tank top links to each other with steam jet vacuum pump, and the secondary steam that liquefied fermented glutinous rice produces in flash tank is sucked steam jet vacuum pump by vacuum, mixes forming mixing steam with live steam at this; (3) mixing steam enters Jet liquefier, at this mixing steam and slip thorough mixing, reaches the purpose that slip heats up and fully liquefies.
The equipment of the technology that liquefied fermented glutinous rice latent heat of the present invention is recycled by: (1) Jet liquefier, (2) pressurize jar, (3) flash tank, (4) steam jet vacuum pump etc. are formed.Jet liquefier (1) directly links to each other with pressurize jar (2); Pressurize jar (2) links to each other with flash tank (3) by pipeline, and flash tank (3) top links to each other with vapor jet pump (4) by pipeline; Vapor jet pump (4) links to each other with Jet liquefier (1) by pipeline.
It should be noted that:
1. pressurize jar (2) is in series by several sometimes, and concrete placed in-line number determined by processing condition and residence time of material, but does not influence enforcement of the present invention, as long as from last pressurize jar liquefied fermented glutinous rice is introduced flash tank;
2. there is secondary or two-stage injection liquefaction sometimes, two Jet liquefiers are promptly arranged, the temperature of liquefied fermented glutinous rice is higher behind secondary (or secondary) steam ejection liquefaction, energy-saving effect is more obvious, second spraying liquefaction back liquefied fermented glutinous rice also will be introduced into the pressurize jar, enter flash tank again, the mixing steam that comes out from steam jet vacuum pump directly enters once or the one-level Jet liquefier, rather than enters secondary (or secondary) Jet liquefier;
3. above-mentioned pressurize jar (2) is sometimes referred to as laminar flow jar, pressure-bearing jar, keep jar or high temperature is kept jar etc.;
4. after liquefied fermented glutinous rice comes out from the bottom of above-mentioned flash tank, enter saccharifying tank sometimes, enter relay tank sometimes, or directly enter pressure filter or other equipment, these do not influence enforcement of the present invention.
Advantage of the present invention is:
1. less investment, instant effect, obvious energy conservation, economic benefit are fairly obvious
2. the energy that is recovered (heat) utilizes on the spot, can not cause any other adverse influence.
Description of drawings is as follows:
Accompanying drawing is a processing unit schematic diagram of the present invention, and wherein (1) is Jet liquefier, and (2) are the pressurize jars, and (3) are flash tanks, and (4) are steam jet vacuum pumps.
Further specify below in conjunction with accompanying drawing and by embodiment:
Embodiment one: produce 30000 tons of corn Citric Acid Plant per year, need 60,000 tons of corns every year approximately, corn is sized mixing with water after crushed, the amount of slip is about 21.6 ten thousand tons, at normal temperatures through the one-level steam ejection liquefaction, temperature reaches 115 ℃, in pressurize jar or laminar flow jar, stopped 1.5 hours, liquefy through two-stage injection again, temperature reaches 130 ℃, enter high temperature and keep jar to stop and entered then in the flash tank in 15 minutes, liquefied fermented glutinous rice is partly vaporized, and temperature is reduced to 98 ℃ by 130 ℃ and entered temporary jar of cooling, enter subsequently to filter and wait other operations, the secondary steam that liquefied fermented glutinous rice produces in flash tank enters steam jet vacuum pump to be mixed the back and enters the one-level Jet liquefier by pipeline and recycle with live steam, can save 11000 tons of steam (by the 0.4MPa saturation steam) every year through adjusting, and is roughly equal to 1,000,000 yuan of Renminbi.
Embodiment two: produce 20000 tons of corn distilleries per year, need 60,000 tons of corns every year approximately, corn is sized mixing with water after crushed, the amount of slip is about 21.6 ten thousand tons, temperature reaches 105 ℃ behind steam ejection liquefaction, pressurize jar pressurize 45 minutes, enter flash tank then and partly vaporize, temperature is reduced to about 90 ℃, is chilled to 60 ℃ in the temporary jar of cooling, enter saccharification in the saccharifying tank, after the liquefied fermented glutinous rice secondary steam that the part vaporization produces in flash tank enters steam jet vacuum pump and live steam mixes, feed Jet liquefier and recycle, through adjusting, can save 5000 tons of steam (by the 0.4MPa saturation steam) every year, be roughly equal to 500,000 yuan of Renminbi.
