Description
Technical field
The present invention is for industry more particularly to one kind such as food, petrochemical industry, chemical industry, papermaking, fermentation, plastics, opto-electronics
Flow anaerobic sludge bed.
Background technology
Up-flow anaerobic sludge blanket (UASB) reactor is Dutch scholar G.Lettinga et al. in early 1970s
Exploitation.Waste water enters reactor by bottom of pond, and by reaction zone, mixed liquor enters settling zone progress solid-liquid point after gas detaches
From.Processed water after clarification is drained by outlet canal, and the microbial solid to precipitate, i.e. anaerobic sludge lean on gravity
Reaction zone is automatically returned to, reactor is discharged by biogas pipe in the biogas that collection chamber is collected.The simple structure of UASB reactors is held
Product load is high, and treatment effeciency is high, easily operated operation, is convenient for maintenance management.The major defect of this reactor is：(1) sludge
After settling zone precipitates, sludge suspension area is returned to by inclined plate landing, and the biogas in sludge suspension area is larger, up
The biogas risen is easy to and the sludge of falling is taken out of, and it is difficult to fall back in Sludge Bed to make sludge；(2) not because of sludge reflux
Into Sludge Bed, water inlet is the bottom in Sludge Bed, and it is difficult the sludge for touching reflux, shadow thus to make the sewage of entrance
Ring the mass transfer of sewage and sludge.
Invention content
The object of the present invention is to provide a kind of simple in structure, solid-liquid-gas separative efficiency height, upstream with long service life
Formula is sick of Sludge Bed.
Purpose to realize the present invention provides following technical scheme：Up flow type is sick of Sludge Bed, it is characterised in that including bed
Body, bed body bottom end are provided with water inlet, and water inlet connects water-distributing device, and the water-distributing device includes gas distribution pipe and is opened in cloth
Qi-emitting hole on tracheae, the nearly top of the bed body are provided with baffle, and baffle center offers sludge rise hole, in sludge rise hole
Side is provided with taper gas gathering mask, and taper gas gathering mask maximum diameter is more than sludge and rises bore dia, taper gas gathering mask end and baffle sheet
10 ~ 20cm of face interval constitutes sludge filtration channel, gas-solid-liquid three phase separation is provided between taper gas collection cover outer wall and bed body inner wall
Device, is provided with downflow weir above gas-solid-liquid three-phase separating device, and the gas-solid-liquid three-phase separating device includes between the upper and lower every setting
The first filter plate, the second porous plate and the V-arrangement deflector being set between the first filter plate and the second porous plate set, the first mistake
Filter plate both ends and bed body inner wall, taper gas collection cover outer wall 30 ~ 40mm of interval.
Preferably, being evenly equipped with a diameter of 1 ~ 2mm micropores on the first filter plate plate body.
Preferably, the second porous plate surface is evenly equipped with the through-hole of a diameter of 10 ~ 15mm.
Preferably, bed body bottom end is provided with sludgd deposition area.
Advantageous effect of the present invention：Structure of reactor of the present invention is simple, low manufacture cost, can real solid-liquid-gas three phase separation,
Substantially reduce production cost.
