Ultrafiltration membrane group for acrylamide production

The utility model discloses an ultrafiltration membrane group feeding ring pipe for acrylamide production. The device comprises a feeding pipe, a discharging valve and a plurality of ultrafiltration membrane groups, the plurality of ultrafiltration membrane groups are connected in series, each ultrafiltration membrane group comprises two ultrafiltration membranes, the two ultrafiltration membranesare communicated in a closed manner, and the device is characterized in that the feeding pipe is connected with a distribution pipe arranged at the bottom of the ultrafiltration membrane group in themiddle; a circle of feeding ring pipe is arranged at the bottom of the ultrafiltration membrane group, and filtrate flows uniformly through a ring pipe shaped like a Chinese character'ri 'formed by the feeding ring pipe and the distribution pipe. By ingeniously improving the structure of the annular pipe, production raw materials are uniform in circulation and not prone to blockage, and the purpose of high efficiency is a
