Description
Technical field
The utility model relates to technical field of sewage, is specifically related to a kind of UASB reactor.
Background technology
UASB upflow anaerobic sludge blanket reactor is a kind of anaerobe method of disposing of sewage, and is upflow anaerobic sludge blanket process again.Sewage passes through UASB from bottom to top.Reactor bottom has a high density, highly active Sludge Bed, and the majority of organic pollutants in sewage is degraded to methane and carbon dioxide through anaerobically fermenting here.Because of the stirring of current and bubble, on Sludge Bed, there is a sludge suspension layer.Reactor top is provided with triphase separator, in order to separating digesting gas, Digestive system and mud granule.Digestion gas autoreactor top is derived; The automatic landing of mud granule is settled down to the Sludge Bed of reactor bottom; Digestive system is from settling section water outlet.UASB portative power is very large, is applicable to the process of high concentrated organic wastewater.The UASB of operational excellence has very high organic pollutant removal rate, does not need to stir, and can adapt to load impact, temperature and pH change by a relatively large margin.
Traditional UASB reactor due to water-distributing device design unreasonable, cause hydraulic mixing not enough, entering organic matter of water can not mix rapidly with mud, can cause and become sour; And water leg is exposed to reaction tank outside by existing UASB reactor, causes the unfairness of reaction tank profile, be unfavorable for the installation of later stage thermal insulation layer.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, provides the UASB reactor of a kind of water distribution of fixing a point, fast water distribution.
For achieving the above object, the utility model discloses following technical scheme:
A kind of UASB reactor, comprise water-distributing device, triphase separator and reactor, water-distributing device comprises the two arc water distributors being located at reactor bottom periphery respectively, the pond body that arc water distributor stretches into reactor is inner, and triphase separator is located at reactor inner chamber top, and triphase separator top is provided with gas skirt, reactor top is provided with methane outlet, the built-in water leg in reactor top, water leg is provided with water outlet, and reactor bottom is also provided with thief hole.
As a kind of preferred version, described water-distributing device in the inner zoning of the pond body of reactor, fixed point water distribution.
As a kind of preferred version, the body inside, pond of described reactor is divided into 7 regions, and the water distributor in each region forms some cloth water branch.
As a kind of preferred version, described 7 regions are the border circular areas of outer six sector regions enclosing in the inside of reaction tank and centre.
As a kind of preferred version, described triphase separator is cone separator.
A kind of UASB reactor disclosed in the utility model, compared with prior art,
(1) water-distributing device zoning, fixed point water distribution.Meet hydraulic mixing needs, ensure that entering organic matter of water mixes rapidly with mud, unit surface water inlet is identical, prevents the generation of becoming sour;
(2) triphase separator adopts cone separator to match with gas skirt, is effectively separated biogas, mud and water;
(3) after improving, built-in water leg, equipment profile are more neat, and the installation of thermal insulation layer is more saved with more convenient.

Embodiment
Also with reference to accompanying drawing, the utility model is further described below in conjunction with embodiment.
Refer to Fig. 1.A kind of UASB reactor, comprise water-distributing device 1, triphase separator 2 and reactor, water-distributing device 1 comprises the two arc water distributors 11 being located at reactor bottom periphery respectively, and the pond body that arc water distributor 11 stretches into reactor is inner; Triphase separator 2 is located at reactor inner chamber top, and triphase separator 2 top is provided with gas skirt, and reactor top is provided with methane outlet 5, and reactor top is built-in is provided with water leg 4, and water leg 4 is provided with water outlet 3, and reactor bottom is also provided with thief hole 6.
Water-distributing device 1 of the present utility model is in the inner zoning of the pond body of reactor, fixed point water distribution, the body inside, pond of reactor is divided into 7 regions, i.e. the border circular areas of inner outer six sector regions enclosing and centre, and the water distributor in each region forms some cloth water branch 12.
In the utility model, triphase separator 2 is cone separator.
Waste water is introduced the bottom of reactor uniformly by water-distributing device 1, sewage is upwards by comprising the Sludge Bed of granule sludge or floc sludge.The biogas (mainly methane and carbon dioxide) produced under anaerobic state causes inner circulation.Some gases formed at sludge blanket are attached on mud granule, adhere to and do not have the gas adhered to rise to reactor head.The mud rising to surface clashes into the bottom of phase reactor 2 gas launcher, causes the mud flco of bubbles attached degassed.After bubble release, mud granule will be deposited to the surface of Sludge Bed, and gas is collected into the collection chamber of the triphase separator 2 of reactor head.Discharge through methane outlet 5, enter sludge gas collecting device.Clear water flows out through water outlet 3 after top water leg 4 is collected.
The above is only preferred implementation of the present utility model; should be understood that; for those of ordinary skill in the art; do not departing under prerequisite of the present utility model; the some improvement can also made the utility model and supplement; these improve and supplement, and also should be considered as protection domain of the present utility model.
