The invention discloses a physicochemical combined- elimination double-loop circulating water supply assembly, which belongs to the technical field of water treatment, and comprises a differential pressure pipe provided with a water inlet, a water outlet, a flow dividing opening and a backflow opening; the water inlet is formed in the upper end part of the differential pressure pipe, and the water outlet is formed in the lower end part of the differential pressure pipe; and the flow dividing opening is formed in the upper portion of the side face of the differential pressure pipe, and the backflow opening is formed in the lower portion of the side face of the differential pressure pipe. And self-locking quick connectors are further arranged on the flow dividing opening and the backflow opening in a sleeving manner. The circulating water supply assembly has the advantages of being low in investment cost and operation cost, convenient to use and simple in structure, double-loop circulation can be achieved, secondary pollution is reduced to the maximum extent, generation of a biological membrane can be obviously slowed down, and the difference of the inner diameters of pipelines of a water inlet area and a water outlet area of the differential pressure pipe can be utilized without adding other devices. And a pressure difference is formed, so that a dead-space-free area is formed.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a dual-loop circulating water supply assembly for physical, chemical, and combined elimination. Background technique [0002] In the mid-1950s, inspired by hemodialysis treatment, hemoperfusion, hemofiltration, blood lipid purification, plasma exchange and other blood purification methods were developed on the basis of hemodialysis. At present, the Japanese Plasauto IQ hemodialysis machine introduced in my country is widely used in clinical practice. [0003] Existing water supply circulation devices for hemodialysis machines and other equipment generally have the problems of high cost, many pipeline parts, easy to lose, and inconvenient cleaning and disinfection of pipelines, mainly because the structure uses many parts, easy to lose, and poor integrity Caused. [0004] How to establish an ideal vascular access that is safer, more reliable, economical and d...
