Large flow barrelless antiosmosis water purification machine system

Abstract

The invention relates to a large flow slot barrelless antiosmosis water purification machine system, comprising a water inlet solenoid valve, a first one way valve, a five-in-one front filter, a booster pump and an RO membrane assembly which are connected in sequence by a pipeline; the pipeline is provided with a water inlet TDS probe and a water outlet TDS probe. A condensed water end of the membrane assembly is connected with a condensed water draining path and a condensed water backflow path; the condensed water draining path is provided with a first combined solenoid valve with a first waste water ratio, a first branch is connected with a flushing solenoid valve, a second branch is connected with a second combined solenoid valve with a second waste water ratio in parallel, the condensed water backflow path is connected with a circulated waste water valve and a second one way valve, and a circulated flushing solenoid valve is arranged between a water inlet end and a water outlet end of the circulated waste water valve by a bypass. The system can realize reuse of the condensed water according to different degrees of water quality characteristics of inlet water, achieves a water saving effect and ensures service life of the RO membrane and a pure water quality.

Description

technical field [0001] The invention relates to a large-flow tankless reverse osmosis pure water machine system, which belongs to the technical field of pure water machine equipment. Background technique [0002] The pure water machine is a kind of water purification equipment that uses multi-stage filter elements for water purification treatment. Its core technology adopts reverse osmosis membrane filtration technology. In addition to effectively removing floating objects in water, heavy metals, bacteria, viruses, etc., it can also Reduce the salinity and small molecular substances in the water body to meet the multiple needs of drinking water in the home or office. However, compared with ultrafiltration, microfiltration and other technologies, the biggest defect of reverse osmosis membrane filtration is the low utilization rate of waste water. Generally, 1 part of pure water needs to be wasted 3 parts of waste water, and the recovery rate of pure water is only 25%. The wo...

Problems solved by technology

[0003] Another limitation in the application of pure water machines is that the water quality differences across the country lead to a generally high maintenance rate of water machines. If a single pure water recovery rate is used for different water quality characteristics, it is easy to cause fouling of the reverse osmosis membrane
