4results about How to "Less flushing" patented technology

This application discloses a water purifier and its flushing control method, relating to the technical field of water purifiers. The flushing control method for the water purifier includes: after the water purifier stops discharging water, checking at least one historical water discharge record; determining whether any historical water discharge record meets preset flushing conditions; ensuring a one-to-one correspondence between the preset flushing conditions and the historical water discharge record; and controlling the water purifier to enter the flushing state if historical water discharge record exists. Therefore, this application has the advantages of improving the flushing quality and water discharge quality of the water purifier, adapting to different usage locations or scenarios, and enhancing the user experience.

The utility model relates to a kind of vapor-liquid separation systems, including separator body, cyclone and external demister device;External demister device is provided with demister, demister separates into steam inlet cavity and steam outlet cavity in external demister device;The one end of external demister device is provided with secondary steam inlet, the bottom of external demister device is provided with second entrainment liquid outlet, the other end of external demister device is provided with purified steam outlet;Secondary steam inlet and second entrainment liquid outlet are all connected steam inlet cavity, and purified steam outlet connects steam outlet cavity;The evaporation steam outlet of separator body is connected the evaporation steam inlet of cyclone;The secondary steam outlet of cyclone is connected secondary steam inlet;The utility model is by being external to demister and being additionally cyclone between separator body and external demister device, can improve demisting efficiency and reduce demister load, to reduce demister flushing frequency, reduce separator cost.

This invention discloses an online water quality monitoring system and control method, belonging to the field of water quality monitoring technology. It includes a processing module, a combined valve, a metering device, a peristaltic pump, and a digester. The metering device has a comprehensive metering chamber, a first auxiliary metering chamber, and a second auxiliary metering chamber, respectively corresponding to the isolated metering of non-strongly corrosive reagents, strong acid reagents, and strong alkali or strong oxidizing reagents. Each chamber is equipped with a photoelectric liquid level sensor to achieve precise volume determination. The processing module controls the injection of wastewater in at least three closed-loop batches. The first batches act as a carrier liquid to push reagents and dilute residues, while the last closed-loop batch replenishes the total volume and cleans the pipelines and chambers of residues, using wastewater to replace the cleaning fluid for self-cleaning. This invention can achieve multi-chamber isolated metering, reagent premixing, parallel detection with dual digesters, or time-sharing detection with a single digester, effectively avoiding cross-reactions between acids / alkalis and redox reagents, reducing cleaning fluid consumption and wastewater production, and improving the stability, detection efficiency, and equipment reliability of multi-parameter online monitoring.

This utility model provides an ultrafiltration filter element, including an outer sleeve and a filter element component. The filter element component includes a filter assembly and a support head. A liquid passage is provided in the middle of the support head, and the filter assembly is disposed within the liquid passage to filter the fluid passing through it. The support head is disposed within the outer sleeve, with one end of the liquid passage located inside the outer sleeve and the other end located outside. The outer sleeve has an inlet and an outlet. This utility model embodiment achieves the technical effect of shortening the backwashing time of the filter element.
