Description
Affiliated technical field
The utility model relates to a kind of pressure type water trap of anaerobic reactor, belongs to the crucial support equipment of high-concentration sewage processing technology field.
Background technology
Distinguishing feature such as Anaerobic Microbiological Treatment Technology has that energy consumption is low, organic volumetric loading is high, surplus sludge volume is few, recyclable biogas utilizes again, easy and simple to handle, investment and working cost are cheap; Handle in municipal administration, sanitary sewage disposal, particularly high-concentration sewage in the practice of (like COD greater than 30000mg/L) and obtain using quite widely.Along with subject development such as microbiology, biological chemistries, people constantly improve anaerobic reactor, have greatly widened the range of application of anaerobic reactor, have obtained the generally good result of approval.
At present, third generation Anaerobic Microbiological Treatment Technology mainly comprises: anaerobic biofilter, anaerobism contact tank, upflow anaerobic sludge blanket reactor (UASB) etc.No matter adopt which kind of anaerobic treatment technology, in general, anaerobic reactor should satisfy two pacing itemss at least efficiently: the one, and retention has a large amount of active anaerobic sludges in the system, and the 2nd, should fully contact between the water inlet of anaerobic reactor and the storage mud.
Fully contact between the water inlet that makes anaerobic reactor and the storage mud, make anaerobic reactor can be in the ideal working order, must guarantee system's water inlet uniform distribution in the reactor drum baseplane.Usually, water distribution system comprises: intake pump, suction culvert, water trap, water distributor, water distribution are first-class.Facts have proved, carry out high-order cloth water dispenser, each water distribution pipeline is only linked to each other with a cloth water spot with a water entry with the water tank (water trap) that is higher than liquid level in the anaerobic reactor; The water outlet place pressure of water trap equates that the water distributor line length equates that the water distribution head place pressure of all water distribution pipelines equates; Water distribution head is identical; Like this, can guarantee that the discharge of sewage that gets into anaerobic reactor through each cloth water spot equates, this is ideal, the most uniform water distribution situation of anaerobic reactor.
The equal open design of traditional water trap is installed in the tip position in the anaerobic reactor.This type is designed with several deficiencies: the situation of (1) water trap below liquid level can't in time be observed.As, water distributor comes off, and causes the short stream of reactor drum water distribution and water outlet, and upflow velocity reduces, and effluent quality descends.(2) because the high-concentration sewage complicated component, jelly, organic content are high, are adsorbed on the water distributor internal surface easily and form incrustation and cause that water distributor is inner to be stopped up, and water trap is pressed close on liquid level to install, and can't be easily the water distributor that has stopped up be dredged.(3) the inside and outside liquid level difference of water trap is little, and water distribution head place discharge pressure is on the low side, and like this, on the one hand, water distribution head causes that easily by the sedimentary sludge blockage of inside reactor water distribution is inhomogeneous, causes bias current, dead angle; On the other hand, the water distribution head discharge pressure is low, and flow velocity is low, and flow is little, and the upflow velocity of sewage is on the low side in the anaerobic reactor, is unfavorable for that anaerobic system normally moves.(4) water trap is installed in the anaerobic reactor, and residue methane content height in the environment is inflammable, explosive in the reactor drum, water trap is carried out very difficult, the danger closes of upkeep operation such as desilting at inside reactor.
Summary of the invention
The purpose of the utility model; Aim to provide a kind of supporting pressure type water trap that is used for anaerobic reactor; Both guaranteed that water distribution was evenly reasonable in the anaerobic reactor; Make reactor drum water inlet and storage mud thorough mixing, the surging force of the anti-water quality load of raising reactor drum guarantees water trap installation itself again, uses, overhauls conveniently.
The utility model is that the technical scheme that is adopted that achieves the above object is: a kind of pressure type water trap of anaerobic reactor; Comprise closed water trap body and annex water distributor joint flange; Wherein, arrange on the water trap body to have: inspection window, vent valve, water intaking valve, outlet valve etc.
The utility model is provided with water intaking valve, and sewage is squeezed into water trap through pump, and the water-in of water trap equates with each water outlet distance of water trap, so pressure difference equates.The outlet valve of water trap bottom is connected with the water distributor joint flange, and sewage is evenly distributed to each water distribution head through water distributor and gets into anaerobic reactor inside under the pressure of intake pump.Inspection window is arranged at the water trap top, can open the inner working condition of inspection water distributor at any time; The top is provided with vent valve simultaneously, can regularly discharge the gas that accumulate water trap inside.
The utility model is closed design, can guarantee that water trap is having operation under the pressure, guarantees the flow velocity of sewage in the water distribution pipeline, thereby guarantees the upflow velocity of inside reactor sewage.The pressure operation can also delay water distributor, water distribution pipeline incrustation.During mediation, except that one road water distribution pipeline, close the valve on the every other water distribution pipeline, like this, the high pressure water that pumps into only passes through from this road water distribution pipeline, realizes the pressure mediation, and all the other water distribution pipelines repeat successively.If stop up more seriously, also can take same measure, but pump into a small amount of diluted acid but not sewage, diluted acid keeps certain hour in the water distribution pipeline, the solvable incrustation of taking off water distributor, water distributor inwall, thus realize the pipeline mediation.
The positively effect of the utility model is following: sealing, high-order cloth water dispenser, and each water distribution pipeline is only linked to each other with a cloth water spot with a water entry, the water outlet place sewage pressure of water trap equates; The water distributor line length equates that the water distribution head place sewage pressure of all water distribution pipelines equates that also water distribution head is identical; Like this, the discharge of sewage that gets into anaerobic reactor through each cloth water spot also equates, can guarantee fully that system's water distribution is more even; The waterpower mixing effect is better, and sewage contacts more abundant with mud, prevents to produce bad water distribution phenomenons such as short stream, bias current, dead angle; Make system's operation more stable, treatment effect is better.Simultaneously, water trap is installed in the outer top of anaerobic reactor cylindrical shell, installs easylier, and space for maintenance is bigger, and upkeep operation is more convenient.
