Description

Technical Field

[0001] The present invention relates to the technical field of membrane separation, in particular to a membrane separation and concentration device. Background Art

[0002] Membrane separation and concentration equipment utilizes a special semipermeable membrane and uses pressure differential as its primary driving force to selectively separate components in a solution. Its ultimate goal is to concentrate solutes or purify solvents. Existing membrane separation and concentration equipment, however, uses a single channel to separate and concentrate substances in a solution, resulting in relatively low separation and concentration efficiency. Using multiple channels to separate and concentrate substances in a solution complicates installation and maintenance, significantly increasing maintenance and installation costs. Existing membrane separation and concentration equipment is also likely to produce a certain amount of precipitation during the separation process. This precipitation accumulates in dead corners within the equipment, further forming condensed dirt, making cleaning inside the equipment even more difficult. Therefore, a membrane separation and concentration equipment is needed that can improve solution separation and concentration efficiency, reduce the tedious installation and maintenance processes, and prevent precipitation accumulation, in order to address the shortcomings of existing membrane separation and concentration equipment.

The separation device 6 in the liquid outlet cylinder 203 will perform secondary separation and concentration on the remaining solution, and then discharge it from the upper end of the connecting pipe 7; when the first solenoid valve 301 of the sampling device 3 is opened, the concentrated and separated solution will enter the first observation cylinder 303 through the first sampling tube 302. The staff can observe the status of the concentrated and separated solution through the first observation cylinder 303. Subsequently, the concentrated and separated solution enters the sampling box 305 from the first observation cylinder 303 and the first U-shaped tube 304, and then reaches the sampling switch 310 through the pressure gauge 311 to realize the observation and sampling function;When the second solenoid valve 308 is opened, the raw liquid enters the second observation tube 307 through the second sampling tube 309. The operator can observe the status of the raw liquid through the second observation tube 307. The raw liquid then enters the sampling box 305 from the second observation tube 307 and the second U-shaped tube 306, and then passes through the pressure gauge 311 to reach the sampling switch 310, thus realizing the observation and sampling function. The slopes at the front and rear ends of the liquid outlet ring 201 and the front and rear ends of the liquid inlet ring 401 prevent sedimentation and accumulation in the solution. The swirl groove 407 is used for flow diversion. The swirl gentle slope 408 prevents sedimentation and accumulation in the solution, making subsequent cleaning more convenient. The first sealing disk 602 and the second sealing disk 606 are used to seal the liquid outlet tube 203 and the liquid inlet tube 403. The filtration gentle slope 610 prevents sedimentation and accumulation in the solution. The separation membrane 611 can be selected with a corresponding pore size according to needs.
