The invention relates to a volute-type gas-liquid separation device which comprises a volute shell, wherein a spiral channel is arranged in the volute shell, a liquid inlet is formed at the outer side of the spiral channel, a gas chamber is arranged above the spiral channel, a reflux port is formed at the bottom of the volute shell, and an exhaust port is formed at the top of the volute shell; gas and liquid enter from the liquid inlet and spirally flow in the spiral channel, bubbles are sufficiently released, upwards move into the gas chamber and are discharged from the exhaust port, and a muddy water mixed solution is refluxed to the bottom of a reactor through the reflux port. The volute-type gas-liquid separation device disclosed by the invention is simple in structure. According to the volute-type gas-liquid separation device, the gas and liquid which are subjected to gas stripping spirally flow in the spiral channel, the gas is sufficiently released, and the muddy water mixed solution is sufficiently mixed, so that the problem of gasp during the movement of the gas and liquid is solved; the gas-liquid separation is more convenient and simpler, so that the gas-liquid separation effect is enhanced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of for when detesting aerobic reactor and carry out sewage disposal to air lift process mixed solution in gas phase (air, biogas) and the device that liquid phase (sewage) separates, belong to the gas-liquid separation technical field in sewage treatment process.
Background technology
Anaerobic reactor and aerobic reactor are all efficient biomembrance process method of wastewater treatment, its inside all needs to arrange Gas-solid-liquid separater, to the gas producing in reaction process, mud granule and muddy water mixed solution are separated (digestion gas, Digestive system and mud granule), by stripping tube, gas-liquid is promoted in gas-liquid separator again, realize gas-liquid separation, muddy water mixed solution is back in reactor, and gas is drained (aerobic reactor) or Returning reactor participates in reaction (anaerobic reactor).
Chinese patent literature CN103011402A discloses a kind of " double-cycling anaerobic reactor ", comprise pond body, pond body is column, in the body of pond, be divided into successively from bottom to top taper sludge bulking district, main reaction region, secondary response district and settling region, this reactor is provided with upper and lower two-stage gas-solid-liquid disengaging zone, two pump around circuit systems comprise stripping tube, gas water separation tank and return line, and the mixing wastewater with air liquid in taper sludge bulking district is promoted to gas water separation tank, form one-level circulation; Gas-liquid in main reaction region rises along stripping tube, forms secondary circulation.
Chinese patent literature CN103332784A discloses a kind of " three grades of circulation aerobic reactors ", in the body of pond, be divided into successively from bottom to top taper sludge bulking district, aerobic reactor zone, hypoxia response district, sedimentation and filtration floor, the top of aerobic reactor zone is provided with one-level gas-solid-liquid disengaging zone, the top in hypoxia response district is provided with secondary gas-solid-liquid disengaging zone, and two-stage gas-solid-liquid is provided with triphase separator in disengaging zone; Mixing wastewater with air liquid in taper sludge bulking district is promoted to knockout drum, the circulation of formation one-level, the gas-liquid in aerobic reactor zone rises along stripping tube, forms secondary circulation, waste water through secondary gas-solid-liquid disengaging zone refluxes to the base injcction of aerobic reactor zone, forms three grades of circulations.
Start fast, can in operational process, comparatively fast generate the features such as aerobic particle mud although above-mentioned reactor has floc sludge, multiple triphase separators and knockout drum need be set, complex structure, cost is high.Bubble in gas-liquid can produce " panting " (stream while breaking when gas-liquid) phenomenon while making gas-liquid operation, the gas-liquid promoting due to stripping tube is entered by the bosom of knockout drum, this in knockout drum " panting " phenomenon cannot be eliminated, will impact gas water separation tank inwall, gas-liquid separation effect and efficiency are poor, also can impact the work-ing life of gas water separation tank simultaneously.
Summary of the invention
The present invention is directed to the deficiency that in existing sewage treatment process, gas-liquid separation technology exists, provide a kind of simple in structure, mass transfer ability is strong, the volute formula gas-liquid separation device of good separating effect.
Volute formula gas-liquid separation device of the present invention, adopts following technical proposals:
This device, comprises spiral case, is provided with helical channel in spiral case, and the arranged outside of helical channel has fluid inlet, and the top of helical channel is air chamber, and the bottom of spiral case is provided with refluxing opening, and the top of spiral case is provided with venting port.
Gas-liquid is entered by fluid inlet, flows at helical channel internal screw, and bubble is fully discharged, and upwards operation enters air chamber, is discharged by venting port, and muddy water mixed solution is back to reactor bottom by refluxing opening.
The present invention is simple in structure, gas-liquid after air lift is flowed at helical channel internal screw, gas is fully discharged, muddy water mixed solution mixes fully simultaneously, play further effect of mass transmitting, " panting " phenomenon while having solved gas-liquid operation, gas-liquid separation is more convenient simple, improve gas-liquid separation effect, extended work-ing life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view along A-A line in Fig. 1.
In figure: 1, spiral case, 2, helical channel, 3, refluxing opening, 4, air chamber, 5, venting port, 6, support, 7, fluid inlet.
Embodiment
As depicted in figs. 1 and 2, volute formula gas-liquid separation device of the present invention, is in spiral case 1, to be provided with helical channel 2, and the arranged outside of helical channel 2 has fluid inlet 7.The top of helical channel 2 is air chamber 4.The bottom of spiral case 1 is provided with refluxing opening 3.The top of spiral case 1 is provided with venting port 5.Spiral case 1 is fixed on support 6.For ease of observing, can on spiral case 1, offer viewing window.
When said apparatus application, stripping tube in anaerobism or aerobic reactor is connected with fluid inlet 7, the gas-liquid of being discharged by stripping tube flows at helical channel 2 internal screws, and bubble moment rapid, high volume discharges, and has improved gas-liquid separation effect and efficiency, " panting " phenomenon while having avoided gas-liquid separation, can not impact inwall, improve its work-ing life, gas is fully discharged, muddy water mixed solution fully mixes simultaneously, has improved mass transfer ability.Gas (biogas) upwards moves and enters air chamber 4, is discharged by venting port 5.Muddy water mixed solution is back to anaerobism or aerobic reactor bottom by the refluxing opening 3 of bottom, mix with the waste water that enters reactor, in reactor, exist anerobe or aerobic bacteria to organic degraded, produce biogas simultaneously, again form gas-liquid, so form circulation, the organic waste water of high density fully contacts with microorganism at short notice, for the Fast-propagation of particulate matter provides sufficient nutrient material, promotes biological self reproducing, waste water is effectively addressed, guarantees stable effluent quality.
