Description
Technical field
The present invention relates to a kind of anaerobic biological reactor.
Background technology
Anaerobic biological reactor has been successfully applied to the processing high concentrated organic wastewater, but when existing anaerobic biological reactor is used to handle organic waste in charging and discharging, there are many problems in aspects such as the guide of gas, especially the residence time of material can't guarantee in the complete hybrid anaerobic biological reactor, and unreacted material completely can directly be discharged reactor.Conventional pulling flow type anaerobe reactor as folded plate type plug-flow bio-reactor, exists stirring efficiency low in through engineering approaches is used, and the plug-flow fluidised form such as is difficult to keep at problem.At present, the research about anaerobic biological reactor mainly is the effect that is conceived to improve solid-liquid separation in the world, prolongs the residence time of material in reactor, has adopted following means: or sediment tube is set at inside reactor; Or increase material and microorganism duration of contact, raising mass-transfer efficiency; Or set up secondary air and stir, form circulation, improve mixing effect etc.But these measures have often increased the volume of anaerobic reactor, and inside reactor structure more complicated, are unfavorable for running maintenance.
Drum-type aerobic composting fermentation jar is widely used in the dynamic aerobic compost field.Tank body tilts to place (inclination angle is less than 3 degree), and its length-to-diameter ratio is big (more than 10: 1).Air is sent in the aerobic fermentation tank from the bottom by air pump, is discharged by the top.Usually only at the charging and discharging two ends pushing plate is set, with promote material into and out of.The pushing plate height has only the some thousandths of of diameter.This aerobic composting fermentation jar is finished fermenting process in the process of advancing.Though have that the material pre-treatment is simple, the residence time fully, good mixing effect, continuously-running, characteristics such as simple in structure; But because the metabolism microorganism is based on anaerobion in the anaerobic reactor, its growth metabolism environment is different with aerobic microbiological, and therefore, this drum-type aerobic composting fermentation jar can not be handled organic waste as anaerobic biological reactor.
Summary of the invention
The objective of the invention is to disclose a kind of spiral flow-pulling tumbling-box anaerobic reactor.This spiral flow-pulling tumbling-box anaerobic reactor can guarantee that the material fluidised form is the spiral pulling flow type, in short churning time, realize mixing, eliminate simultaneously axial mixing effect largely, avoid the complete material of unreacted to run off too early, guarantee the residence time of material, and then help reaction smoothly and efficiently carry out.
In order to achieve the above object, the middle discovery that studies for a long period of time that the present invention is carrying out drum-type aerobic composting fermentation jar: the change of raising plate structure of internal layout can mix fully to material, and has avoided the problems such as inside whipping device corrosion of popular response device.Further improvement and perfect of axial plug-flow characteristic with drum reactor will help the ripe feed separation of life in the reactor.To the optimization of the length-to-diameter ratio of cylinder, can prolong the water conservancy residence time (HRT) and the solid retention time (SRT) of material, reach the abundant purpose of fermentation.Comprehensively above-mentioned, aerobic composting fermentation jar advantage can be extended to the anaerobically fermenting field.
Concrete technical scheme of the present invention is: comprise motor, cylindrical shell and bearing.Place the cylindrical shell on the bearing to be made up of shell, inner core and chuck, its constitutional features is: be consolidated with the design requirements spacing on the inwall circumference of inner core and spaced apartly axially raise plate and spiral is raised plate; Axially raising plate is made up of 2～4 quadrangular plate of evenly arranging, the plate face of every quadrangular plate extends and can overlap with the cylindrical shell central shaft, spiral is raised plate and is made up of 2～4 blocks of fan-like pattern plates of evenly arranging, the central shaft of every block of fan-like pattern plate and cylindrical shell is 30～60 ° of angles, and adjacent quadrangular plate and fan-like pattern plate are staggeredly arranged.The two ends of cylindrical shell are provided with capping, and the rotating shaft of the intrinsic hollow in center of capping, rotating shaft place in the inherent bearing support of bearing top, and the cylindrical shell horizontal plane is tilted, and slanted angle is 3～15 °; By belt rotating shaft is connected with motor, and controls the rotating speed and the rotational time of cylindrical shell by the time relay.Wherein be provided with the vapor pipe and the feed-pipe that connect with inner core in the rotating shaft of an end, feed-pipe is connected with feed chute with fresh feed pump successively, also is provided with the hot water inlet pipe in the rotating shaft, and the hot water inlet pipe is communicated with the hot water water inlet bend pipe that connects chuck.Be provided with the discharge nozzle that connects with inner core in the rotating shaft of the cylindrical shell the other end, and the hot water outlet pipe by being communicated with hot water effluent's bend pipe that chuck connects.Be provided with mechanical seal and packing seal double seal in the rotating shaft.
Being shaped as of above-mentioned cylindrical shell is cylindrical, and its L/D ratio is (6: 1)～(10: 1).
Above-mentioned quadrangular plate is rectangle or square, 1/4～1/3 of the radius that its height (axially) is an inner core.
The arc length of above-mentioned fan-like pattern plate be inner core diameter 0.7～0.95.
Two adjacent groups is raised the spacing of plate for axially raising 1/2～2/3 of plate length.
The present invention has following effect and advantage:
Since the present invention in inner core, adopted unique spiral and raise axially that plate has carried out alternately, dislocation, layout at interval, therefore make inside reactor material fluidised form pulling flow type in the shape of a spiral, material can be realized mixing in short churning time, eliminate simultaneously axial mixing effect largely, thereby avoided the complete material of unreacted to run off too early, guarantee that material has the sufficient residence time, and then help reaction smoothly and efficiently carry out.
2. replace, misplace, arrange at interval owing to having adopted spiral in the inner core of the present invention and axially having raised plate, compare hydrogen output raising 50% with the anaerobic reactor that use is traditional.
3. owing to cylindrical shell horizontal tilt of the present invention, slanted angle is horizontal by 3～15 °, so headspace is abundant, is convenient to the enrichment and the guide of gas.
4. reactor of the present invention is compared with the complete hybrid anaerobic reactor of routine, has saved the mechanical stirring system.Therefore, the present invention has simple in structure, is convenient to the advantage of running maintenance.
