一种四塔低压吸附真空解吸制备氧气的装置和方法
摘要：
本发明公开了一种四塔低压吸附真空解吸制备氧气的装置和方法，该装置包括鼓风机、2个真空泵、4个吸附塔、2个均压罐和氧气缓冲罐，其中4个吸附塔的进口相连，并连接到鼓风机和2个真空泵，4个吸附塔的出口相连，并连接到氧气缓冲罐，4个吸附塔通过管道分别都与2个均压罐连接。采用了本发明的技术方案，能够提高氧气产量和收率，解决现有VPSA制氧工艺氧气利用率低、吸附剂利用率低、设备造价高的缺点。
摘要（英）：

The invention discloses a four-tower low-pressure adsorption and vacuum desorption device and method for preparing oxygen. The device comprises an air blower, two vacuum pumps, four adsorption towers, two pressure-equalizing tanks and an oxygen buffering tank, wherein the inlets of the four adsorption towers are connected, and the inlets are connected to the air blower and the two vacuum pumps, the outlets of the four adsorption towers are connected mutually and are connected to the oxygen buffering tank, and all the four adsorption towers are connected to the two pressure-equalizing tanks through pipelines. According to the technical scheme, the oxygen yield can be increased, and the shortcomings of an existing VPSA oxygen preparing technology that the utilization ratio of oxygen is low, the utilization ratio of adsorbents is low, and the equipment cost is high are avoided.
