发酵设备题，急急急急急！！！帮忙解答: 3.设计一年产20000吨味精（纯度99.5%）的发酵工厂（年生产天数按330记），工艺数据如下：提取率：97%，产酸率为11%，发酵罐发酵周期为32小时，生产周期45小时；接种量为7%，种子培养时间16小时，生产周期为24小时，染菌率按1%估计。请计算：（1）若选... 3.设计一年产20000吨味精（纯度99.5%）的发酵工厂（年生产天数按330记），工艺数据如下：提取率：97%，产酸率为11%，发酵罐发酵周期为32小时，生产周期45小时；接种量为7%，种子培养时间16小时，生产周期为24小时，染菌率按1%估计。请计算：（1）若选用公称容积为200M3发酵罐，发酵罐装填系数75％，则发酵罐数量应是多少？种子罐的公称容积和数量应是多少？（2）发酵温度为32ºC，每1M³发酵液每小时传给冷却器的Z大传热量为4.18×6000KJ/(M³.h），采用竖式蛇管换热器，K=4.18×500KJ/(M².h.C），冷却水由20ºC升至27ºC，假设产生的热量全部传给冷却器，求单位时间内冷却水的用量及需要多大冷却面积。我的误区如下：（1）发酵罐 N＝nt／24＋1 n为每24小时进料罐数 n是否应为生产周期／24，而t为发酵周期，则 N＝（45÷24）×32÷24＋1＝3.5 种子罐N＝（24÷24）×16÷24＋1＝5／3 罐数怎么为分数和小数？而种子罐公称容积我就不会了，请告诉我一下。（2）对于冷却水耗量W＝Q／C（T′－T）但比热C如何求？ .现有30M³酵罐一台，实际容量20M³若料液（密度为1046kg/M³，比热为3.94KJ/Kg）采用连消方式进行灭菌，整个灭菌在1.5小时完成。（1）请计算采用连消灭菌流程时，120ºC灭菌所需蒸汽用量及蒸汽管直径？（蒸汽间接加热，假设无热量损失，蒸汽压力表压0.4MPa，该压力下蒸汽的焓为2747.27KJ/Kg，蒸气密度为2.62kg/M³，蒸汽在管道中的流速为42m/s，物料进连消系统加热器的温度为70ºC）题中用的应该是热量的恒等计算冷却水耗量W＝Q／C（T′－T）则Q＝C（T′－T）×W 料液的温差是120－70吗？那蒸汽的温差在哪？展开

英语高手帮忙翻译段英文谢谢！！: In this paper， the degradation of an azo dye Orange G (OG) on nitrogen-doped TiO2 photocatalysts has been investigated under visible light and sunlight irradiation. Under visible light irradiation， the doped TiO2 nanocatalysts demonstrated ... In this paper， the degradation of an azo dye Orange G (OG) on nitrogen-doped TiO2 photocatalysts has been investigated under visible light and sunlight irradiation. Under visible light irradiation， the doped TiO2 nanocatalysts demonstrated higher activity than the commercial Dugussa P25 TiO2， allowing more efﬁcient utilization of solar light， while under sunlight， P25 showed higher photocatalytic activity. According to the X-ray diffraction (XRD)， X-ray photoelectron spectroscopy (XPS) and UV–vis spectra analyses， it was found that both the nanosized anatase structure and the appearance of new absorption band in the visible region caused by nitrogen doping were responsible for the signiﬁcant enhancement of OG degradation under visible light. In addition， the photosensitized oxidation mechanism originated from OG itself was also considered contributing to the higher visible-light-induced degradation efﬁciency. The effect of the initial pH of the solution and the dosage of hydrogen peroxide under different light sources was also investigated. Under visible light and sunlight， the optimal solution pH was both 2.0， while the optimal dosage of H2O2 was 5.0 and 15.0 mmol/l， respectively. Azodyes， which are characterized by the presence of one or more azo bonds ( N N )， are among the most notorious widespread environmental pollutants associated with textile，cosmetic， food colorants， printing， and pharmaceutical indus-tries. Because of their non-degradability， toxicity， potential mutagenicity and carcinogenicity， wastewaters originating from these dyes production or application industries pose a major threat to the surrounding ecosystems and human beings’ health.[1–3].Environmental concerns and the need of meeting the strin-gent international standards for rejecting wastewaters has made the development of novel and cost-effective processes for the puriﬁcation of azo dyes efﬂuents an issue of major technological importance. 展开
