Background technology
Airlift reactor mainly is divided into two big class, i.e. internal circulation gas-lift type reactor and outer circulation airlift reactors.Two kinds of reactors mainly are to distinguish according to different fluid circulating paths.When aeration in the up-flow district, because the difference of the apparent fluid density that empty gas holdup difference causes in the ascending, descending stream district finally causes fluid at the reactor internal recycle.The internal circulation gas-lift type reactor is considered to introduce in the gas-liquid bubbling bed upspout or a baffle plate makes fluid at different regional internal recycle.
Cell response is the thermopositive reaction very responsive to temperature variation.Therefore, the design of bio-reactor is had relatively high expectations to temperature controlled.Particularly along with increase, its heat of reactor volume are removed an important content that will become reactor design with temperature control.In the cell response 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 generate energy, wherein a part can provide thalli growth and generate meta-bolites, and another part discharges with form of heat, generally the heat that discharges is during the fermentation called heat of fermentation.Different according to used bacterial classification and technology, the peak value of heat of fermentation is deviation to some extent, is about 1.17 * 10 as the peak value of heat of fermentation in the L-glutamic acid production process
4Kcal/ (m3h), the peak value of fermenting lysine heat is about 1.8 * 10
4Kcal/ (m3h); And the heat of fermentation of yeast is bigger, is about 2.2 * 10 as the peak value of heat of fermentation in the alcoholic fermentation process
4Kcal/ (m3h), the peak value of the pichia spp that has heat of fermentation during the fermentation can reach 2.4 * 10
4Kcal/ (m3h).The said products 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 leavening temperature of biological heat production peak phase out of control.If it is longer that leavening temperature exceeds the time remaining of optimum temperature range, growth, the metabolism of producing bacterium are all seriously influenced.Can water coolant be fed in the chuck or serpentine tube 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 serpentine tube, the advantage of plate-fin heat exchanger be heat transfer efficiency height, compact construction, light and handy and firmly, big, the good economy performance of adaptability etc., but the report that plate-fin heat exchanger is applied to the internal circulation gas-lift type reactor is not arranged as yet at present.
Summary of the invention
The purpose of this utility model provides a kind of internal circulation gas-lift type reactor of built-in plate-fins interchanger, solves present chuck or the serpentine tube heat transfer efficiency is lower, is unfavorable for regulating the problem of temperature.
The utility model is achieved through the following technical solutions: the internal circulation gas-lift type reactor of built-in plate-fins interchanger comprises the internal circulation gas-lift type reactor; Described internal circulation gas-lift type reactor internal upper part is provided with plate-fin heat exchanger, there are steam inlet and cooling water outlet flange in the plate-fin heat exchanger upper end, there are vapor condensation water out and entrance of cooling water flange in the lower end, wherein, steam inlet and cooling water outlet flange are linked to be an integral body to plate wing heat exchanger fin by pipeline one, and vapor condensation water out and entrance of cooling water flange are linked to be an integral body to plate wing heat exchanger fin by pipeline two.
The plate wing heat exchanger fin of described plate-fin heat exchanger is plate shape, and pipeline one and pipeline two are straight tube.
The plate wing heat exchanger fin of described plate-fin heat exchanger is fan-shaped, and pipeline one and pipeline two are endless tube.
Be flexible connection between described plate-fin heat exchanger and the internal circulation gas-lift type reactor.
Described flexible connection is that strut member is connected with bolt.
Adopt the positively effect of technique scheme: the utility model is applied to the internal circulation gas-lift type reactor with plate-fin heat exchanger, utilize a plurality of plate wing heat exchanger fins of plate-fin heat exchanger to carry out thermal exchange, overcome the deficiency of chuck or serpentine tube 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 plate wing heat exchanger fins also help lend some impetus to fluid turbulent, increase the mass transfer coefficient of reactor; In addition, will change flexible connection between plate-fin heat exchanger and the internal circulation gas-lift type reactor, can maintenance for convenience detach greatly.
