Technical field
The utility model relates to a kind of boring aeration device of the MBR of being applicable to system membranes scouring aeration, belongs to biological sewage treatment equipment technical field.
Background technology
The main composition of the perforated pipe aerating regulation system of the actual use of engineering is at present: bottom aerating pipelines, air delivering pipeline, gas blower.By gas blower, air is delivered to bottom aerating pipelines by air delivering pipeline, utilize the perforation of arranging on aerating pipelines to realize aeration.This aerating system generally can not be out of service, because after fan parking, because of the existence of back pressure; warm air can be suppressed in aeration tube; time is slightly long, and on aeration tube, the mud in aeration aperture can be subject to heat drying, stop up aperture, and and then causes the phenomenons such as the smooth or bubble of aeration is inhomogeneous.In Membrane Bioreactor for Wastewater Treatment system, film is cleaned aeration generally all will adopt the boring aeration mode of air pocket, and for save aeration consumption, often adopts again intermittent aeration, therefore easier blocking aeration hole.Stopping up and causing aeration not smooth because of aperture often appears in common boring aeration mode in the practical engineering application of membrane bioreactor, thereby causes that film is dirty stifled, finally affects the running environment of whole process system.As shown in Figure 1, 2, traditional boring aeration system comprises: bottom aerating pipelines, air delivering pipeline, compressed air source unit (gas blower).Operational scheme is comparatively simple, is divided into aeration operation phase and aeration stop phase.The aeration operation phase, open blower fan, warm air arrives bottom aerating pipelines through gas pipe line, utilizes the perforation of arranging on pipeline to realize aeration.Aeration stop phase, closes blower fan, stops aeration.After this stage fan parking, because of the existence of back pressure, because of the existence of back pressure, warm air can be suppressed in aeration tube, and the time is slightly long, and on aeration tube, the mud in aeration aperture can be subject to heat drying, stop up aperture, and and then causes the phenomenons such as the smooth or bubble of aeration is inhomogeneous.
Utility model content
The purpose of this utility model is to provide a kind of boring aeration device of the MBR of being applicable to system membranes scouring aeration, and this device has anti-clogging plug and cleaning function.
The purpose of this utility model is achieved through the following technical solutions, a kind of boring aeration device that is applicable to MBR system membranes scouring aeration, comprise gas blower, air delivering pipeline, bottom aerating pipelines, gas blower connects bottom aerating pipelines by air delivering pipeline, on the aerating pipelines of bottom, set out pore, bottom aerating pipelines end is also provided with check valve, be exposed to airborne air delivering pipeline and be provided with exhaust branch pipe, exhaust branch pipe is provided with electrically operated valve, also be provided with PLC controller, PLC controller is realized the electrically operated valve of connection and the interlock control of gas blower.
Further, described valve is electric butterfly valve.
Compared with prior art, the utlity model has following beneficial effect:
The first, bottom aerating pipelines end is provided with check valve, and pneumatic tube is provided with the valve communicating with atmosphere.Utilize the variation realization introducing mud of pressure reduction in start and stop blower fan process to recharge Chi Diguanlu in the fan parking stage by sewage; guarantee that pipeline is full of and cleans; warm air in vent pipe simultaneously; guarantee that aeration aperture mud can not stop up aperture because of local heating's mummification; aerating pipelines under full packages state; utilize sewage in pipe to bore a hole and carry out back flushing aeration tube in the blower fan restarting stage, can guarantee that perforation is without mud or the obstruction of microorganism flco.
The second, the working process of boring aeration device that is applicable to MBR system membranes and cleans aeration:
Aeration phase: gas blower start operation, pond face valve closes, aeration phase: gas blower start operation, pond face valve closes, air enters boring aeration pipeline, and under pressure, check valve is in closing condition, some perforation that air sees through aeration tube top or bottom enter pond, thereby realize oxygenic aeration effect.
Stop aeration phase: gas blower is out of service, pond face valve open, now communicate with atmosphere because aerating pipelines is inner, relative pressure vanishing (absolute pressure is a normal atmosphere), thereby with the outside pressure difference (h) that forms of aerating pipelines, under the effect of pressure difference, check valve is opened, enter a part of water (containing mud) and enter aerating pipelines by check valve, a part of water enters aerating pipelines through some apertures of aerating pipelines top or bottom in addition, the warm air of aerating pipelines inside is discharged from by pond face valve like this, aeration tube is interior in moisture state.
Again transport aeration phase: close pond face valve, start gas blower, gas is filled with bottom aerating pipelines, tube fluid utilization blasts gaseous tension and discharges through aeration tube perforation, perforation is carried out to secondary scouring, stop up without mud or microorganism flco guaranteeing, wait managing after interior sewage discharges completely, carry out normal operating phase.
