accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the reverse osmosis control device in the utility model embodiment.
embodiment:
In order to reduce the running cost of reverse osmosis system, avoid sewage to the implementation of the severe contamination of reverse osmosis membrane, the utility model embodiment provides a kind of reverse osmosis Controlling System, is described preferred embodiment of the present utility model below in conjunction with Figure of description.
The utility model embodiment provides a kind of reverse osmosis control device, and this device comprises: equalizing tank, liquidometer, low-pressure pump, low-pressure pump first inlet valve, strainer, low pressure pump outlet valve, reverse osmosis membrane, low-pressure pump second inlet valve, high-pressure pump, high pressure pump outlet valve, dense water out valve, product water out valve and by-pass valve, equalizing tank is provided with liquidometer, be connected by low-pressure pump first inlet valve between low-pressure pump with equalizing tank, be connected with low-pressure pump by low pressure pump outlet valve with between strainer, low-pressure pump is provided with low-pressure pump second inlet valve rinsed for controlling reverse osmosis membrane, strainer is connected with high-pressure pump, be connected by high pressure pump outlet valve between high-pressure pump with reverse osmosis membrane, reverse osmosis membrane is provided with dense water out valve, produce water out valve and chemical cleaning pump, produce between water out valve and strainer and be provided with the by-pass valve rinsed for controlling reverse osmosis membrane, liquidometer, between high-pressure pump and low-pressure pump, interlock device is installed.Reverse osmosis control device also comprises: be provided with under meter between low pressure pump outlet valve and strainer, conductivity instrument and tensimeter; Tensimeter is provided with between strainer and high-pressure pump; Under meter is provided with, conductivity instrument and tensimeter between reverse osmosis membrane and product water out valve.
Low-pressure pump second inlet valve is used for, when blocking appears in reverse osmosis membrane, controlling low pressure pump inlet with or without flow; Low pressure pump outlet valve is for controlling low pressure pump outlet with or without flow; The by-pass valve of reverse osmosis membrane is for controlling the back flushing of reverse osmosis membrane; Low-pressure pump first inlet valve is used for reverse osmosis control device and normally carries out into controlling entrance during water with or without flow; High pressure pump outlet valve is for controlling the size of high pressure pump outlet flow; Whether dense water out valve is used for controlling to be sent by dense water; Produce water out valve whether to send for the product water controlling reverse osmosis membrane.Under meter is for showing the flow of water inlet and product water, and conductivity instrument is for showing water inlet and producing electrical conductivity of water indicator value.Strainer is used for the biology in filter sewage, and adopts gac to filter, and prevents from damaging reverse osmosis membrane, increases system operation cost.
During the initialize of reverse osmosis control device, low-pressure pump and high-pressure pump are in halted state, close all valves, namely close low-pressure pump first inlet valve, low pressure pump outlet valve, reverse osmosis membrane by-pass valve, low-pressure pump second inlet valve, high pressure pump outlet valve, dense water out valve and produce water out valve.
