The utility model relates to a decarbonization pump for purification of propylene carbonate, which comprises a pump body (1) and a main shaft (2), two ends of the pump body (1) are provided with bearing pads, and the main shaft (2) is connected and matched with the bearing pads, which is characterized in that the bearing pads are replaced by a separating n \u2011 1232 tapered roller bearing (3). After reforming the decarbonization pump, the utility model has the following advantages: 1. The operation cycle of the decarbonization pump is increased, and the maintenance frequency is reduced. 2. The consumption of machinery and materials has been reduced. Before the transformation, each shift needs to add about 15kg of mechanical lubricating oil. Now, it is unnecessary to add it. The annual cost saving is nearly 190000 yuan (15 \u00d7 3 \u00d7 365 \u00f7 170 \u00d7 2000 yuan). 3. Reduce the risk of potential safety hazards, and solve the problem that the lubricating oil is brought into the propylene carbonate into the decarburization system to block the packing tower due to the wear of the bearing bush of the decarburization pump for a long time. 4. Reduce the cleaning cycle of the packing tower, reduce the labor force of the staff, reduce the outsourcing resources and reduce the labor cost.

一种碳酸丙烯酯净化用脱碳泵
本技术属于合成氨净化工艺设备,涉及一种碳酸丙烯酯净化用脱碳泵。
技术介绍
在合成氨生产中,由于制气原料主要是碳和含氮化合物,经制气和一氧化碳变换后,变换气中除含有对氨合成有用的氢气等,同时还含有二氧化碳、一氧化碳、甲烷、硫化氢等对氨合成等气体,在这些杂质组分中又以二氧化碳的含量最高。如在生产过程中,不及时将二氧化碳从变换气中除去,将会使后续工序无法正常进行。碳酸丙烯酯法是碳酸丙烯酯为吸收剂的一种脱碳方法,而脱碳泵运行的介质就是碳酸丙烯酯,在生产过程中,之前轴瓦式脱碳泵运行经常出现泵与轴瓦3a磨损严重,运行周期短检修频繁,严重时出现烧瓦情况;同时瓦与轴磨损时会造成将润滑油带入脱碳泵中,与杂质接触容易堵塞填料,从而给化工生产带来安全隐患。
