Description
Technical field
The utility model belongs to the stirring reactor field, relates to a kind of stirring reactor of built-in plate-fins heat exchanger.
Background technology
Bioreactor is to realize microbial fermentation, cell culture of animals, produces the indispensable equipment of various biological products and fermented product, and its effect is enhancing mass and heat transfer, for microorganism or animal and plant cells provide stable growing environment.There has been multiple bioreactor to come out at present, can be divided into mechanical stir-reactor, airlift reactor and air bubble type etc. by its hybrid mode, they can be used in the production of some predetermined substance respectively, and important impetus is played in the development of biotechnology industry.
Cell effect is the exothermic reaction very responsive to variations in temperature, therefore, the design of bioreactor is had relatively high expectations to temperature controlled, and particularly control will become the important content that reactor designs with temperature along with increase, its heat of reactor volume are removed.In the cell effect process, reactor needs to adopt the effective type of cooling to reduce temperature to produce heat.For example, during the fermentation, thalline decomposition nutrition matter and produce power, wherein a part can provide thalli growth and generate metabolite, and another part discharges with form of heat, generally the heat that discharges is during the fermentation called fermentation fever.Different according to used bacterial classification and technology, the peak value of fermentation fever is deviation to some extent, is about 1.17 * 10 as the peak value of fermentation fever in the glutamic acid production process
4Kcal/ (m3h), the peak value of fermenting lysine heat is about 1.8 * 10
4Kcal/ (m3h); And the fermentation fever of yeast is bigger, is about 2.2 * 10 as the peak value of fermentation fever in the alcoholic fermentation process
4Kcal/ (m3h), the peak value of the Pichia pastoris that has fermentation fever during the fermentation can reach 2.4 * 10
4Kcal/ (m3h).The said goods biological heat production during the fermentation is big, and especially in the summer of sweltering heat, it is very difficult to lower the temperature, and often causes the fermentation temperature of biological heat production peak phase out of control.If it is longer that fermentation temperature exceeds the time remaining of optimum temperature range, growth, the metabolism of producing bacterium are all seriously influenced.Can cooling water be fed in the chuck or coiled pipe of reactor by Artificial Control or control automatically at present, lower the temperature by heat exchange, temperature is constant relatively in the maintenance reactor.Plate-fin heat exchanger is a kind of emerging thermal design technology, cooling method than chuck or coiled pipe, the advantage of plate-fin heat exchanger be heat transfer efficiency height, compact conformation, light and handy and firmly, big, the good economy performance of adaptability etc., but the report that plate-fin heat exchanger is applied to stirring reactor is not arranged as yet at present.
Summary of the invention
The purpose of this utility model provides a kind of stirring reactor of built-in plate-fins heat exchanger, solves present chuck or the coiled pipe heat transfer efficiency is lower, is unfavorable for regulating the problem of temperature.
The utility model is achieved through the following technical solutions: the stirring reactor of built-in plate-fins heat exchanger comprises stirring reactor; Plate-fin heat exchanger with a plurality of fanning strip wing heat exchanger fins is set in the described stirring reactor, there are steam inlet and coolant outlet flange in the plate-fin heat exchanger upper end, there are steam condensate (SC) outlet and cooling water inlet flange in the lower end, wherein, steam inlet and coolant outlet flange are linked to be an integral body to fan-shaped plate wing heat exchanger fin by endless tube one, and steam condensate (SC) outlet and cooling water inlet flange are linked to be an integral body to fan-shaped plate wing heat exchanger fin by endless tube two.
Be flexible connection between described plate-fin heat exchanger and the stirring reactor.
Described flexible connection is that support member is connected with bolt.
Adopt the good effect of technique scheme: the utility model is applied to stirring reactor with plate-fin heat exchanger, utilize a plurality of fanning strip wing heat exchanger fins of plate-fin heat exchanger to carry out exchange heat, overcome the deficiency of chuck or coiled pipe heat transfer type, make heat transfer efficiency improve greatly, be conducive to accuracy control over temperature, be conducive to reduce cooling water amount, even utilize normal-temperature water can reach the effect of temperature control, simultaneously, a plurality of fanning strip wing heat exchanger fins also help lend some impetus to fluid turbulent, increase the mass tranfer coefficient of reactor; In addition, will change flexible connection between plate-fin heat exchanger and the stirring reactor, can maintenance for convenience detach greatly.
