Description
Technical field
The present invention relates to a kind of decompression release device, belong to water treatment field.
Background technology
The basic procedure of water treatment is that water intake pumping station draws water, and is transported to distribution reservoir through water delivery manometer tube, then by coagulation, precipitate, filter, send into city tap-water pipe network after the link such as sterilization.
Former water is after water intake pumping station pressurizes, and owing to pressure increases, the molten tolerance in water is also greatly increased, the distribution reservoir of water treatment plant it is transported to, after entering coagulative precipitation tank, owing to pressure reduces together with water body, gas release in water, causes flco absorption bubble to produce and floats, have impact on sedimentation effect.
On the other hand, when the interior river that former hydromining flow velocity is low, when summer, algae was broken out in a large number, the flocculation basin of waterworks and sedimentation tank surface can the flcos of floating one layer of bubbles, these flcos are difficult to sink, and have a strong impact on sedimentation effect, even affect effluent quality, cause filter tank to block, shorten backwashing period.Experiment finds, during alga eruption, former oxygen in water reaches saturated dissolved oxygen concentration, and has the strongest regularity, i.e. daytime former oxygen in water concentration high, evening is low, explanation is the impact of algae photosynthesis, generates a large amount of oxygen, causes a large amount of gases release in water, cause flco absorption bubble to produce to float, have impact on sedimentation effect.
The oxygen dissolution that high pressure solution gas and algae photosynthesis produce is in water, form the sightless minute bubbles of naked eyes, these micro-bubbles exist the most at water source, being difficult in water treatment procedure release, the measure such as the drop of existing pipeline air exhaust water, distribution reservoir, coagulation stirring is limited to these micro-bubble removal effects.
In water, saturated dissolved oxygen concentration is relevant with temperature and pressure, and at the same pressure, temperature is the highest, and saturated dissolved oxygen concentration is the lowest；Under identical temperature conditions, pressure is the lowest, and saturated dissolved oxygen concentration is the lowest, it is clear that by changing the dissolved oxygen concentration method cost height that former coolant-temperature gage reduces in water, unrealistic.Therefore we have invented a kind of by the method for supersaturation dissolved oxygen in decompression release water, underwater bubble effusion can be accelerated.
Summary of the invention
The purpose of the present invention is aiming at the problem that above-mentioned prior art exists, it is provided that efficient, easy, feasible device accelerates supersaturation dissolved oxygen and the release of gas in water, specifically a kind of decompression release device.
The present invention is achieved in that a kind of decompression release device, it is characterized in that: include outgassing groove, water inlet relief pipe, outlet pipe, water inlet relief pipe, outgassing groove, the outlet pipe through connection of series connection；Being provided with the semipermeable membrane of permeable watertight in described outgassing groove, outgassing groove is divided into two parts by semipermeable membrane, and top is air chamber, and bottom is gas-liquid separation chamber；The exhaustor of the external vacuum pump of air chamber of described outgassing groove, the both sides of the through gas-liquid separation chamber being connected to outgassing groove of described water inlet relief pipe, outlet pipe.
Described water inlet relief pipe had one section of water inlet relief pipe body risen before be connected through with outgassing groove, and water inlet relief pipe water inlet position elevation is less than the position elevation of water inlet on outgassing groove.
Described water inlet relief pipe had the water inlet relief pipe body of one section of vertical ascent before be connected through with outgassing groove.
Described outgassing groove is flat sealing flume.
The upper and lower of described semipermeable membrane is respectively provided on two sides with upside micropore fixed plate, downside micropore fixed plate, and semipermeable membrane is placed in upside between micropore fixed plate, downside micropore fixed plate.
Present configuration rationally simple, manufacture easy, easy to use, present invention is mainly used in water treatment field before coagulative precipitation tank, it is effectively reduced owing in water, gas discharges the phenomenon of the flco absorption bubble caused, substantially increase the treatment effect of sedimentation tank, there is wide market prospect.Particular content is that device is made up of relief pipe of intaking, outgassing groove, outlet pipe 3 sections in series at water-supply-pipe terminal tandem one decompression release device, and water inlet relief pipe, by rising certain height in vertical direction, reduces the pressure of water in pipeline；Outgassing groove is flat sealing flume, and owing to discharge section area increases, water velocity reduces, beneficially gas release in water.Outgassing groove is separated into two parts by semipermeable membrane, top is air chamber, bottom is gas-liquid separation chamber, former water enters gas-liquid separation chamber after water inlet relief pipe decompression, owing to pressure reduces, the gas effusion being dissolved in water, air chamber is entered by the semipermeable membrane of permeable watertight, vacuum pump is utilized to discharge, in order to fix semipermeable membrane, upper and lower two-layer is set and has the clamping plate (fixed plate) of multiple micropore, i.e. upside micropore fixed plate, downside micropore fixed plate, semipermeable membrane is fixed in the middle of upside micropore fixed plate, downside micropore fixed plate.For increasing the contact area of gas-liquid separation, outgassing groove can be arranged as required to as multiple structure.Complete the water body after outgassing to send through outlet pipe.
The present invention is simple and practical, it is not necessary to existed system is carried out big transformation, does not has other power consumptions in addition to utilizing minipump and bleeding.
