Abstract
A method for reclaiming the afterheat of steam in the production of gourmet powder features that the secondary steam and condensed water generated in baking corn embryonic buds, protein powder and fibrous dregs are recovered and then used in the concentrating procedure of corn milk, fermented liquid and waste liquid.
Description
Technical field
The present invention relates to the glutamate production field, the recoverying and utilizing method of steam drying waste heat in specifically a kind of glutamate production process.
Background technology
At present, in the glutamate production process, utilize steam material to be dried processing mostly as thermal source.Its method normally, primary steam makes materials such as maize germ, albumen powder, fiber finer slag remove moisture content by the tube bank dryer.After reaching drying requirement, dried material output, the indirect steam and the condensed water of generation directly efflux.
But the direct discharging of indirect steam and condensed water has caused environmental pollution, energy waste on the one hand; On the other hand, the some multi-effect evaporators in the glutamate production process use a large amount of primary steams again separately, have increased the production cost of monosodium glutamate.
Summary of the invention
Technical assignment of the present invention is at above-mentioned the deficiencies in the prior art, and the recoverying and utilizing method of steam drying waste heat in a kind of energy-conservation, glutamate production process of being easy to realize is provided.
Technical assignment of the present invention is realized in the following manner: the indirect steam and the condensed water that produce in maize germ, albumen powder, the fiber finer slag oven dry processing procedure are reclaimed, and its waste heat is used for the concentration process of corn steep liquor, zymotic fluid and waste liquid.Whole process forms the utilization again of steam waste heat.
This method may further comprise the steps:
A, primary steam produce 90～95 ℃ indirect steam and condensed water behind tube bank drying machine drying material;
B, indirect steam reclaim by blower fan; Condensed water enters flash tank and dodges chilling but, vapor-liquid separation;
The steam that c, vapor-liquid separation obtain mixes with indirect steam, and pipeline is delivered to the multi-effect evaporator place in corn steep liquor, zymotic fluid and the waste liquid enrichment process, and corresponding product is carried out concentration;
The condensed water that drying course obtains among vapor-liquid separation process and the step a among d, the step b is as process water.
Described primary steam refers to: direct steam by the boiler output.
Respectively controlling parametric optimization in the multi-effect evaporator is: mixed vapour amount 5～6m
3/ h, vacuum-0.08～0.1MPa, 65～85 ℃ of temperature, charging rate are 18～25m
3/ h, discharging concentration 20～22 Baume degrees.
The condensed water that the vapor mixing process produces among vapor-liquid separation process and the step c among the step b is preferred for fermentation batching or the boiler feed water aspect in the production of gourmet powder.
The recoverying and utilizing method of steam drying waste heat compared with prior art has following outstanding beneficial effect in the glutamate production process of the present invention:
(1) formation full cut-off road is recycling, and indirect steam is all recycled, and has both saved the energy, has protected environment, has reduced the production cost of monosodium glutamate again;
(2) transformation that only need do on the simple pipeline just can realize the present invention, low, the easy realization of improvement cost.
The specific embodiment
Explain with the recoverying and utilizing method of specific embodiment below steam drying waste heat in the glutamate production process of the present invention.
Embodiment:
The generation of mixed vapour:
Maize germ to be dried is sent in the tube bank machine from charging aperture by feeding packing auger, temperature is that 180～190 ℃ primary steam enters from the tube bank machine other end with the flow velocity of 10～20m/s, steam and maize germ counter current contacting, the time of staying of control material in the tube bank dryer is 8～12min, outside maize germ to be dried back discharge up to standard machine, finished product warehouse-in, drying course generation temperature are 90～95 ℃ indirect steam and condensed water.
Equally, in the oven dry processing procedure of albumen powder, fiber finer slag, also can produce 90～95 ℃ indirect steam and condensed water.
The indirect steam that each several part produces reclaims by blower fan; Enter after condensed water mixes flash tank dodge chilling but, vapor-liquid separation.The steam that vapor-liquid separation obtains mixes with indirect steam, and pipeline is delivered to multi-effect evaporator.The condensed water that vapor-liquid separation obtains mixes the back and reclaims with the condensed water that drying course obtains.

(2) with 6m
3The flow velocity of/h is delivered to the multi-effect evaporator of zymotic fluid enrichment process with mixed vapour, utilizes the waste heat heating concentrated broth of mixed vapour.The multi-effect evaporator relevant parameter is: the charging rate 20～23m of zymotic fluid
3/ h; Vacuum-0.01～0.01MPa; 75～80 ℃ of temperature; Zymotic fluid discharging concentration 20～21 Baume degrees.
(3) with 5.5m
3The flow velocity of/h is delivered to the multi-effect evaporator of waste liquid enrichment process with mixed vapour, utilizes the waste heat heating concentrating spent liquor of mixed vapour.The multi-effect evaporator relevant parameter is: the charging rate 20～24m of waste liquid
3/ h; Vacuum-0.04～-0.01MPa; 70～75 ℃ of temperature; Waste liquid discharging concentration 20～21 Baume degrees.
The use of condensed water:
Condensed water a, b are delivered to storage tank, are used for aspects such as fermentation batching, boiler feed water.
Calculate with the glutamate production scale of producing 10000 tons per year, use this exhaust heat recovering method after, can save 10,000 m
3Primary steam, the glutamate production cost reduces by 1,100,000 yuan.
