Background technology
Simple in structure, advantages such as organic loading is high, wide adaptability that upflow type anaerobic reactor has have been widely used in the processing of various trade effluents.
Trade effluent enters anaerobic reactor by water distributor by the bottom of reactor, fully contact with anaerobion at reaction zone, the generation biochemical reaction forms methane, produce a large amount of bubbles, bubble is carrying water and mud, form the mixture that gas-liquid contains mutually admittedly, rise together and enter triphase separator, at first collide reflection cone, cause the separation of mud gas, mud mixture after the degassing enters and carries out mud-water separation the settling region from going into head piece, and the supernatant liquor after the separation is drained from the settling region, and mud is precipitated to get off and get back to inside reactor through refluxing opening.In the triphase separator of routine, go into head piece and refluxing opening overlaps.
For anaerobic reactor, the quality of triphase separator separating effect directly influences the separating effect of mud gas in the reactor, thereby affects the efficient of anaerobic reaction, so triphase separator is very crucial part in the anaerobic reactor design.
Conventional triphase separator mainly contains following problem: go into head piece and refluxing opening overlaps, make between the current of the mud of a large amount of backflows and rising and interfere with each other, not thorough simultaneously gas separated can enter the settling region with mud, influenced the sedimentation of mud, can not keep has very high sludge concentration in the reactor.
Improved triphase separator go into head piece and refluxing opening separates, can improve deposition efficiency, but exist baroque problem, if design is unreasonable, may make into that water enters the settling region from refluxing opening, cause mud to be difficult to be back to reaction zone.
Summary of the invention
The purpose of this invention is to provide a kind of simple, effective triphase separator, can solve the COINCIDENCE PROBLEMS that head piece and refluxing opening are gone into by triphase separator sludge settling district, improve the solid separating effect of gas-liquid, keep sludge settling district liquid stream stable, improve the waste water of anaerobic reactor and remove efficient.
The present invention is by the following technical solutions:
The present invention is made of the taper guide shell on reflection cone, the reflection cone, the cylindrical guide shell at taper guide shell center and the gas hood of upper end.The top lower outside of taper guide shell is provided with vapor pipe, and the gas hood top also is provided with vapor pipe, is provided with the circular channel between taper guide shell and the cylindrical guide shell, is provided with annular overflow ducts between taper guide shell and the top gas hood.
Outstanding feature of the present invention is that the taper sludge settling zone center at the triphase separator of routine is provided with the cylinder shape guide shell, and cylindrical guide shell top and bottom are fixed on the taper guide shell by support.
Connect by cone between triphase separator of the present invention and the reactor shell, reactor shell is provided with insulation jacket outward.
The present invention has following advantage: 1) by the cylinder shape guide shell is set in the settling region, according to the difference of mud backflow resistance with muddy water go into head piece and refluxing opening separately, simple in structure, build easily; 2) be provided with gas skirt at the top, can after reflection cone separates, drain by remaining a small amount of gas; 3) reactor shell and triphase separator junction are the taper of an expansion, can increase the circulation area of mixed stream, reduce the pressure of liquid level top, and the easier come-up of gas is removed.
