Abstract
The present invention is one kind of ultrafiltering apparatus and its application method. The ultrafilter includes material tank, circulating pump, ultrafilter and jet pipe, with the circulating pump and the ultrafilter constituting closed loop ultrafiltering system. Controlling the valve connected to the outlet of the ultrafilter can realize batched intermittent operation and continuous operation. The concentrated liquid is not returned directly to the material tank and contacted with outer air, and this can avoid the oxidizing deterioration of some air-sensitive matter in the liquid to be processed, and avoid some easy-to-bubble matter to bubble and overflow, resulting in shortened processing period.
Description
technical field [0001] The invention relates to an ultrafiltration device and an application method thereof, in particular to an ultrafiltration device using a jet tube to self-suction feed, and a method for applying the device. Background technique [0002] In the unit operation of ultrafiltration, there have always been two structures, one structure such as figure 1 Shown: The feed liquid is supplied to the feed pump from the feed tank through the feed valve, and the feed liquid is pumped into the ultrafilter by the feed pump through the control valve. Under the pressure, part of the feed liquid becomes ultrafiltrate, and the other part does not. The permeated feed liquid is enriched with macromolecular substances such as particles, colloids, proteins, bacteria, etc., and returns to the feed tank as a concentrated liquid. The material in the trough is continuously concentrated, and when it reaches a certain level, the operation is stopped, an...
