Description
Technical field
The invention belongs to water treatment field, in particular to a kind of frequency conversion Pressure behaviour oxygen-increasing device.
Background technology
The molecular oxygen be dissolved in the water is called dissolved oxygen, is usually denoted as DO, represents with the milligram number (mg/L) of oxygen in every premium on currency.Dissolved oxygen number be weigh the important index of of water quality quality, therefore in most water treatment procedure, oxygenation is a requisite link.How for different situations, different oxygenation ways is adopted also to be the problem that water treatment field faces.Oxygenation way popular at present:
Can be divided into from gaseous species: oxygenating air and pure oxygen oxygenation.Oxygenating air as aeration sand head, micropore aeration pipe, water surface oxygenating machine etc.Pure oxygen oxygenation as ceramic capillary air dipelling disk, dissolved oxygen cone etc.The efficiency far of pure oxygen oxygenation is higher than oxygenating air.
Can be divided into from gaseous phase: static oxygen increasing and dynamically oxygenation.Static oxygen increasing be directly by air release in needing in water body to be processed.Dynamic oxygenation injects required water body to be processed with certain pressure again after gas and water being first effectively mixed to form high-oxygen water.Dynamic oxygenation efficiency far is higher than static oxygen increasing.
The dynamic pure oxygen oxygenation existed at present is pressure oxygenation tank or pressure dissolved oxygen cone.This type of technology effectively can use oxygen and reach certain oxygenation effect, but also there is following defects and deficiency:
1. can not ensure that tank internal pressure is stablized thus can not ensure that dissolved oxygen value is stablized: under actual behaviour in service, the amount that heavy-oxygen-enriched water uses is inconstant, it is little when time is large, this is by unstable for the hydraulic pressure caused in tank/cone, thus make the dissolved oxygen of high-oxygen water in tank/cone unstable, and then the dissolved oxygen of the water body of required process is caused not reach requirement.
2. can not independently set regulating tank internal pressure thus oxygen dissolving value in setting tank can not be regulated: because the pressure in tank/cone can not be set as certain value, the oxygen dissolving value in tank/cone is caused to set, thus accurately can not control oxygen, make the water body of required process reach required dissolved oxygen.
3. water pump can not cause that energy consumption is high and human cost is high by start-stop automatically: owing to not adopting converter technique, cause water pump full-load operation always, thus it is high to consume energy, and also causes needing Attended mode thus human cost increases.
4. dissolved oxygen efficiency is not high enough: in tank/cone water and oxygen to connect true face large not, the dissolved efficiency that result in oxygen reduces.Generally can only reach the oxygen utilization rate of 60-75%.Thus when injecting staying water, produce the effusion of large oxygen bubbles.
5, the frequent open and close of gas solenoid valve: only have single level sensor, causes gas solenoid valve frequently to open and close, and increases failure rate, and may cause hydraulic pressure and dissolved oxygen instability in tank.

After the index reached required for after the every instruction (as dissolved oxygen value, temperature, volume etc.) fully understanding staying water and process, by scientific algorithm, determine required tank body and pump technology parameter (as tank body size, discharge of pump and power etc.).Pending water from water pump control modules and the oxygen from Oxygen control module are injected tank body 1 by the present invention's design simultaneously, in tank body 1, form certain pressure.Due to the one that the filler 6 of filling in tank body 1 is in polyhedron hollow material, micropore shape material or flaky material, drastically increase the contact area of water and oxygen.Under pressure, water and oxygen have carried out mixing very fully through the process of filler 6 to bottom from tank body 1 overhead stream simultaneously, time bottom arriving, pending water defines the high heavy-oxygen-enriched water of oxygen dissolving value, and heavy-oxygen-enriched water is discharged with dynamic form by water outlet 4 under pressure.
Principle of work and flow process:
By the upper liquid level of two level sensors 28 to required maintenance on mobile transparent liquid level observation pipe 27 and the location point of lower liquid level.Open water pump frequency conversion device 15, water pump 14 and oxygen hose 9, now pending water injects tank body 1, and increase with rate of water added, in tank body 1, water level rises gradually, when water level arrives the level sensor 28 of upper end, magnetic valve 24 will be opened automatically, and oxygen starts to inject tank body 1, and liquid level declines thereupon, when liquid level drops to lower end level sensor 28, magnetic valve 24 will cut out automatically, and oxygen stops injecting, and liquid level starts to rise.Constantly repeatedly, liquid level will remain between two level sensor positions described process always.
Along with heavy-oxygen-enriched water flows out or the change of aquifer yield size from exit, pressure in tank body will constantly change, if when the pressure in tank body is less than set pressure, pump variable frequency device 15 is receiving pressure transmitter 10 signal and will automatically increase the running speed of water pump 14 after treatment, water pump 14 aquifer yield increases tank body 1 internal pressure simultaneously thereupon and also will increase, until tank body 1 internal pressure reaches set pressure, pump variable frequency device 15 will maintain pump rotary speed automatically to ensure to be stabilized in set pressure in tank body 1 afterwards.If when water outlet 4 is closed, after tank body 1 internal pressure also reaches set pressure, automatic closing water pump 14 operates by pump variable frequency device 15, and magnetic valve 24 also automatically will cut out and stop injecting oxygen simultaneously.
When needing to adjust the oxygen dissolving value of heavy-oxygen-enriched water, can be reset tank body 1 internal pressure value by man-machine touch screen.If be provided with higher force value, then the oxygen dissolving value of heavy-oxygen-enriched water can improve.Otherwise the oxygen dissolving value of heavy-oxygen-enriched water can reduce.
Heavy-oxygen-enriched water of the present invention is the water body bottom portion (i.e. dynamic-form oxygenation) injecting required process with certain pressure, therefore can improve the dissolved oxygen of staying water rapidly, and any waste does not occur.
