Description
Technical field:
The utility model belongs to technical field of sewage, is specifically related to a kind of spiral-flow water-distribution hydrocyclone internal-circulation anaerobic reactor.
Background technology:
The anaerobic waste water biotechnology is because its huge processing power and potential application prospect are the focuses of water technology research always.Develop into pandemic now UASB technology from traditional anaerobism contact process, the anaerobic waste water treatment technology reaches its maturity.Further outstanding along with contradiction between factors such as production development and resource, energy consumption, occupation of land, existing anaerobic technique is faced with stern challenge again, especially how process for producing develops a large amount of high concentrated organic wastewaters that bring, and the anaerobic technique that makes research and development technology economy more optimize is very necessary.The internal circulating anaerobic treatment technology is exactly the efficient treatment technology that produces under this background, it is to be researched and developed successfully by Dutch PAQUES company, and push international waste water treatment engineering market, be successfully applied in the wastewater treatments such as beer, citric acid at present, fermentation such as alcohol class waste water is invested reasons such as huge because of COD concentration height, SS content height, old scrap build difficulty, overseas equipment, fails well to be utilized always.And the water distribution in its structure of UASB reactor of present widespread usage adopts the ring type coil pipe more, one or more posticums on coil pipe, the i.e. water distribution manner of " a pipe a bit " or " a pipe multiple spot ", adopt a tapered cap and separator to collect to the biogas that produces, this water distribution manner only produce vertically (on, stirring down), exist and easily form " channel " and " short circuit ", mud can not mix uniformly with waste water, and long-time running, stopping up can appear in posticum, and reactor is big more, and water distribution uniformity is difficult more, make reactor produce a large amount of invalid volumes, the low defective of biogas purity of output.
Summary of the invention:
The purpose of this utility model provides a kind of less investment, it is fast, stable to start, handle load height, anti impulsion load, mass transfer effect are good, the institute's granule sludge that forms activity height, the high spiral-flow water-distribution hydrocyclone internal-circulation anaerobic reactor of biogas purity that produces.
The technical solution of the utility model is: a kind of spiral-flow water-distribution hydrocyclone internal-circulation anaerobic reactor, establish water distributor in the cylindrical tank bottom, and it is characterized in that: the triphase separator of in tank body, establishing center stand column support and connection middle part gas collector and top; Gas collector is separated into upper and lower two reaction chambers with tank body; Be laid with cyclone water distributor in tank base, establish gas-liquid separator on triphase separator upside and the cyclone water distributor correspondence position; Establish between gas-liquid separator and triphase separator and the gas collector carry tracheae be communicated with cyclone water distributor between establish return line and be communicated with.
Wherein, establish overflow weir on the described triphase separator upside inner tank wall.
Establish guiding device at the bottom of the described tank body, guiding device is to be made of bottom center's flow deflector and the flow deflector that is laid with along the edge.
Described cyclone water distributor is made up of taper water distribution cover, three water distributors, and the nozzle on three water distributors is evenly distributed on the taper water distribution cover inwall of same horizontal plane, and water spraying direction and taper water distribution cover lower edge circumference are tangent.
Described triphase separator all is to be made of two-layer a plurality of taper gas skirts that are staggered in mutual isolated four identical slot type plenum chambers with gas collector, and the plenum chamber side plate openings is connected with the taper gas skirt.
Described gas-liquid separator utilizes pipe to be connected with carrying tracheae, return line, methane recovery, carries the tracheae tangent line and enters gas-liquid separator, and methane recovery utilizes pipe to be installed in the gas-liquid separator top, and return line is installed in the gas-liquid separator bottom.
Because when adopting the technique scheme water inlet, after organic waste water enters anaerobic reactor, most organism is digested at following reaction chamber, the biogas that following reaction chamber produces is intercepted by gas collector, enter plenum chamber by putting forward the fermentation liquid-phase mixing in the gas tube and tube, fermented liquid density descends in causing managing, and and the higher fermented liquid of pipe outer density between produced density difference, impel fermented liquid constantly to be promoted to gas-liquid separator, isolate the fermented liquid behind the biogas, because there is liquid level difference, turn back to down reaction chamber by return line again, thereby formed the circulation of fermented liquid successive, made mud be in sufficient swelling state, improved anaerobic digestion speed and organic loading; And the liquid of the whirlwind-type water distributor that adopts stream is made circumferential motion along same direction in swirler, in reactor, form eddy flow, cause the omnibearing stirring of liquid, produce eddy current, make mud be not easy deposition, increased the mass transfer effect of mud and organic waste water, thus have less investment, stable, handle that load height, anti impulsion load, mass transfer effect are good, the institute's granule sludge that forms activity height, the high advantage of biogas purity of producing
