Description

Upflow type anaerobic reactor
Technical field
The present invention relates to a kind of upflow type anaerobic reactor.
Background technology
Anaerobic Microbiological Treatment Technology is compared with traditional aerobe treatment technology, has the organic loading height, does not need a large amount of dilution waters; The purification efficiency height; The nutrition requirement is few; Do not need aeration, energy consumption is low, and working cost is low; Impact load and envrionment conditions have stronger adaptive faculty; Can produce biogas recycles as clean energy; Sludge yield is low, and the biological sludge of generation is easy to dehydration; Advantages such as reactor volume is little, and floor space is few.Be widely used in the processing of the middle and high concentration organic waste water of industries such as light industry, chemical industry, pharmacy, obtained effect preferably.That application is the most successful at present is upflow anaerobic sludge blanket reactor (UASB).
Waste water advances people's anaerobic reactor by water distributor at the bottom of by the pond, fully contacts with anaerobion at reaction zone waste water, produces the intensive biochemical reaction, and organism mainly is decomposed into biogas (CH by anerobe here 4, CO 2, H 2O etc.), produce a large amount of small biogas bubbles, bubble converges gradually in uphill process and increases and carry mud, water and rise together and enter triphase separator.Triphase separator (gas, solid, liquid separator) is made up of settling region and collection chamber (or claiming gas skirt), and the at first separated laggard people's collection chamber of gas (cover) is discharged reactor by the biogas pipe; Muddy water mixed solution after gas delivery enters the people settling region and carries out solid-liquid separation, and the waste water after the clarification is discharged reactor by effluent trough, and the anaerobic sludge that precipitates turns back to reaction zone by action of gravity by the seam that refluxes.The separation of above-mentioned mud, water, biogas can be finished by a triphase separator.
For high efficiency anaerobic reactor,, must in these devices, triphase separator be set in order to guarantee to keep the mud of q.s and good effluent quality in the anaerobic digestion device.And the quality of triphase separator separating effect directly has influence on separating of gas and mud and treat effluent in the device, thereby has influence on the success or failure of reactor operation.Therefore in DESIGN OF REACTOR, the design of triphase separator is a very crucial part.There is following problem in the bright domestic and international widely used anaerobic reactor of order:
Gas in gas, mud, the water mixed liquid enters the settling region, and promptly mud and water mixture are before entering the settling region, and gas does not separate removal effectively, owing to the solid, liquid separating effect is disturbed in gas leakage to the settling region.Precipitated isolating mud can not turn back to rapidly in the reactor, and can not keep has very high sludge concentration and long sludge age in the reactor.
Summary of the invention
Technical scheme to be solved by this invention provides a kind of separating effect that can improve anaerobic reactor biogas, mud, water mixed liquid, keep settling region liquid stream stable, keeping has very high sludge concentration and long sludge age in the reactor, improve the upflow type anaerobic reactor of volume of equipment utilization ratio.
The present invention adopts following technical scheme:
The present invention includes reactor shell, be arranged on the reactor shell lower end the water distributor water pipe, be arranged on reactor shell upper end constitute triphase separator by taper guide shell and the gas hood that is arranged on taper guide shell upper end, be provided with circular channel one between the cover wall lower end of gas hood and the taper guide shell barrel, be provided with circular channel two between the last barrel of taper guide shell and reactor shell, the gas hood top is provided with the biogas vapor pipe, be provided with the settling region cylindrical shell in the upper end of reactor shell, the top of settling region cylindrical shell is provided with effluent trough.
The present invention is arranged between the settling region cylindrical shell of reactor shell upper end and the reactor shell and adopts tilting reflector to be connected.
The barrel of the present invention and the corresponding anaerobic reactor cylindrical shell of taper guide shell barrel lower end position is made of tilting reflector.
The wide-mouth of gas hood of the present invention and taper guide shell constitutes air chamber, and the gas hood top is provided with vapor pipe.
The wide-mouth of taper guide shell of the present invention is embedded in the gas hood.
Taper guide shell of the present invention and gas hood are by supporting the upper end that channel-section steel is fixedly installed on reactor shell.
Positively effect of the present invention is as follows:
Two circular channels of the present invention combine mud-water separation and gas-water separation are finished at different sites, the good separating effect of gas, mud, water, thus avoided in the traditional triphase separator mixing liquid rising passway and the mud shared passage mud water current that reflux that reflux to disturb bigger problem.
Adopt the present invention can keep settling region liquid stream stable, flow-shape makes it have the good solid-liquid separating effect near the laminar flow shape.
The circular wide-mouth on taper guide shell of the present invention top and cylindric gas hood constitute an air chamber and the bigger gas-liquid separation interface that volume is bigger, can effectively reduce the rate of release of biogas and the steam amount of carrying secretly of discharge reactor shell.
Adopt the gas in gas of the present invention, mud, the water mixed liquid can not enter the settling region cylindrical shell, be that mud and water mixture are before entering the settling region cylindrical shell, gas can separate removal effectively, avoids owing to the solid, liquid separating effect is disturbed in gas leakage to the settling region.
The present invention is arranged between the settling region cylindrical shell of reactor shell upper end and the reactor shell and adopts tilting reflector to be connected effective like this settling region volume that increased.Adopt the precipitated isolating mud of the present invention to turn back to rapidly in the reactor, very high sludge concentration and long sludge age are arranged in the reactor to keep.
