摘要：【中文】本发明涉及一种节能含硫烟气制硫酸转化装置，包括依次联通的干燥塔、鼓风机，其出气口依次联通第一换热器、预转化换热器，预转化换热器的入气口连接第一换热器的出气口，其出气口分别联通转化器的预转化段和转化器一段，气体经第一换热器降温后，经管道联通至转化器二段的进气口；省煤器I，其进气口连接转化器二段的出气口，出气口连接转化器三段的入气口；余热锅炉，其进气口连接转化器三段的出气口，其出气口通过管道连接吸收塔。原料气SO2浓度提高，设备规格减小，单位产能投入降低，转化工艺流程短，节省了管理成本和人员成本；在转化工艺中，由于SO2气体浓度的提高，使得转化反应余热增加，利用余热锅炉充分回收了转化余热。 【EN】The invention relates to an energy-saving sulfur-containing flue gas sulfuric acid preparation conversion device, which comprises a drying tower and an air blower which are communicated in sequence, wherein the air outlet of the air blower is communicated with a first heat exchanger and a pre-conversion heat exchanger in sequence; the gas inlet of the economizer I is connected with the gas outlet of the second section of the converter, and the gas outlet of the economizer I is connected with the gas inlet of the third section of the converter; and the air inlet of the waste heat boiler is connected with the air outlets of the three sections of the converter, and the air outlets of the waste heat boiler are connected with the absorption tower through pipelines. The concentration of the raw material gas SO2 is improved, the equipment specification is reduced, the unit productivity investment is reduced, the conversion process flow is short, and the management cost and the personnel cost are saved; in the conversion process, the concentration of SO2 gas is increased, SO that the conversion reaction waste heat is increased, and the conversion waste heat is fully recovered by using a waste heat boiler.

摘要：【中文】本发明涉及具有神经保护活性的多二硫键长链肽，以及其药学上可接受的盐和包含其的药物组合物。这些多二硫键长链肽能够通过对谷氨酸受体的抑制作用减少细胞钙内流，从而起到保护皮层神经元免受谷氨酸引发的兴奋性毒性，是一类非常有效的神经保护剂。 【EN】The present invention relates to a multi-disulfide long chain peptide having neuroprotective activity, and pharmaceutically acceptable salts thereof and pharmaceutical compositions comprising the same. These long-chain disulfide peptides can reduce intracellular calcium influx through inhibition of glutamate receptors, thus protecting cortical neurons from glutamate-induced excitotoxicity, and are a very potent neuroprotective agent.
