Description
Technical field
The utility model belongs to wet production cornstarch technical field, relates in particular to the hydro-thermal use device in a kind of cornstarch production process.
Background technology
Starch is the basic material of food industry, is mainly used in industries such as starch sugar and alcohol, maltodextrin, monosodium glutamate, system are moulded, papermaking, pharmacy, fermentation.4,500 ten thousand tons of whole world starch yields, starch more than 90% is all from corn, but with corn produce starch have raw material abundance, technical maturity, powder rate height, production cost low, be not subject to seasonal restrictions advantage such as anniversary production, cornstarch industry has developed into global new industry, the wet-milling industrial development of corn is rapid, the seed each several part be can separate effectively, highly purified starch and byproduct produced.The processing method of wet production cornstarch is: soak, corase grind, correct grinding (to plumule extract the separation of fiber), the operations such as drying of separation, starch washing and the starch of albumen, obtain highly purified starch product.In the cornstarch process tube bank condensed water directly discharged or by after being cooled to 20-30 ℃ as the starch washings, in the drying process of starch, the condensed water that starch pneumatic conveying drying radiator produces directly discharged or cooled to 20-30 ℃ after as the starch washings, the temperature of tube bank condensed water has about 130 ℃, the temperature of pneumatic conveying drying condensed water has about 130 ℃, these a large amount of high-temperature water are not fully utilized, and cause great waste.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and the hydro-thermal use device in a kind of cornstarch production process is provided, and this apparatus structure is simple, small investment, easy for installation, take up an area of little, can save a large amount of heat energy, reduce production costs, improve economic benefit of enterprises.
For solving the problems of the technologies described above, the technical solution of the utility model is: the hydro-thermal use device during cornstarch is produced, comprise pipe bundle drier and starch pneumatic conveying drying radiator, also comprise boiler and hot-water cylinder, condensation-water drain on the described pipe bundle drier is connected with the top of hot-water cylinder by the tube bank condensate pipe through drain valve, the condensation-water drain of described starch pneumatic conveying drying radiator is connected with the top of hot-water cylinder by the pneumatic conveying drying condensate pipe through drain valve, the delivery port of described hot-water cylinder bottom is connected with the water inlet of boiler by hot-water line, is connected with heat-exchanger pump on hot-water line.Pipe bundle drier and starch pneumatic conveying drying radiator condensed water enter in the hot-water cylinder respectively by drain valve, and then hot water is got to boiler the inside by heat-exchanger pump, boiler changes into steam to hot water and is used for producing, the temperature of condensed water has about 120 ℃, be converted into the steam about 190 ℃, can save a large amount of heat energy.
Be equipped with hot water valve on tube bank condensate pipe described in the utility model, pneumatic conveying drying condensate pipe and the hot-water line.By closing hot water valve, can regulate inflow at any time.
Boiler described in the utility model is a low-pressure boiler.The chlorine root of tube bank steam condensate (SC) and pneumatic conveying drying condensed water is 5-8mg/L, hardness＜0.03m.moL/L, can satisfy the boiler feedwater requirement of the industry.
Compared with prior art, the beneficial effects of the utility model are:
Because the hydro-thermal use device during cornstarch of the present utility model is produced, comprise pipe bundle drier and starch pneumatic conveying drying radiator, also comprise boiler and hot-water cylinder, condensation-water drain on the pipe bundle drier is connected with the top of hot-water cylinder by the tube bank condensate pipe through drain valve, the condensation-water drain of described starch pneumatic conveying drying radiator is connected with the top of hot-water cylinder by the pneumatic conveying drying condensate pipe through drain valve, the delivery port of described hot-water cylinder bottom is connected with the water inlet of boiler by hot-water line, is connected with heat-exchanger pump on hot-water line.With the inventor's practical application explanation, if directly discharge with the condensed water of prior art, 720 tons/day of the vapour in cornstarch workshop, then every day, boiler was with handling 720 tons in water.If use the technical solution of the utility model, the utilization rate more than 90% is arranged after the condensed water reuse, thus 648 tons of conserve water, the expense of handling one ton of water is by 4.5 yuan, then saves water resources taxes to be: 648 * 4.5 * 300 days=87.48 ten thousand yuan.
Because the making full use of of thermal source, the temperature of pure processing water are at 20 ℃, and the temperature of condensed water reclaims 648 tons water yield day about 120 ℃, then save heat energy: (120-20) * 648 * 1kcal/Kg. ℃=64800 * 10
3Kcal, during 190 ℃ of saturated vapors, specific enthalpy is 665kcal/kg, then day saving quantity of steam is 97 tons, and 29100 tons of year saving quantity of steams are if produce one ton of vapour coal consumption 145kg, then year is sparing in the use of coal 4219.5 tons, coal is by one ton 850 yuan, and then a year saving expense exists: ten thousand yuan of 4219.5 tons * 850=358.66,1 year cost-saved 446.1 ten thousand yuan.
