Abstract

The utility model relates to a waste water treatment reactor, in particular to an anaerobe sieve-plate tower, which comprises a reactor, a water inlet arranged at the bottom of the reactor, a water outlet disposed on the upper portion of the reactor, a gas discharging tube and a triphase separator arranged inside the reactor, wherein a sieve-plate on which through holes are distributed is positioned between the lower portion of the triphase separator and the water inlet. The anaerobe sieve-plate tower enhances the sludge-water mixing effect inside the anaerobic reactor.

Description

The anaerobe sieve-tray tower
Technical field
The utility model relates to a kind of waste water treatment reactor, particularly a kind of anaerobe sieve-tray tower.
Background technology
Along with the continuous development of society and the enhancing of people's environmental consciousness, wastewater processing technology has caused people's extensive concern.The anaerobism technology is the first-selection in the waste water innoxious process for treating, and anaerobic reactor is the key equipment in the anaerobic waste water treatment technology.
Up-flow anaerobic sludge blanket (being called for short UASB) is the anaerobic reactor that is most widely used in the current field of waste water treatment.For improving the internal mix effect of UASB, industry member is generally by two kinds of approach: 1) increase the inside reactor rate of flow of fluid, as expanded granular sludge bed (being called for short EGSB) technology; 2) adopt gas to put forward technology, as inner circulation reactor (being called for short IC) technology.Yet the former causes the reactor operating restraint to narrow down, and the actual motion effect is not good enough, and the latter is difficult to control because of technical sophistication, promotes difficulty.
The utility model content
The utility model purpose is to provide a kind of anaerobe sieve-tray tower for strengthening the inner muddy water mixed effect of anaerobic reactor.
The technical solution of the utility model is: a kind of anaerobe sieve-tray tower, comprise reactor, the water-in of reactor bottom, the water outlet on top and escape pipe are arranged at the triphase separator in the reactor, at the sieve plate that is furnished with through hole below the triphase separator to setting between the water-in.
Described sieve plate is horizontally disposed, and through hole can be a circular hole on the sieve plate, also can be the through hole of other arbitrary shape.
Below the triphase separator between the water-in one deck sieve plate being set, also two layers or more sieve plate can be set.
When below the triphase separator two layers or more sieve plate being set between water-in, the upper strata percentage of open area is greater than lower floor, and described percentage of open area is meant the area of whole through holes on the sieve plate and the ratio of sieve plate area.
Between reactor top water outlet and bottom water-in, water circulation pipe can be set.
The utility model is to improve on the basis of the structure of prior art UASB or EGSB, increase sieve plate (or claiming porous plate) at inside reactor, when making the current of inside reactor flow through sieve plate, form jet, through hole on the sieve plate (or claiming sieve aperture) is little and many, be evenly distributed, make the current uniform distribution of inside reactor on the whole.
The utility model effect: after the inside reactor of anaerobe sieve-tray tower is set up sieve plate, when the current of inside reactor were flowed through sieve plate, flow velocity increased, and the regional area of through hole top forms jet, mud and water form fluidisation in the fluerics, thereby have strengthened the mixed effect of inside reactor; Flow velocity when the subsidence rate of the mud of sieve plate top is flowed through through hole above current, mud can not pass through sieve plate, enters the below of sieve plate, and is final, the mud of inside reactor is segmented in several different spaces because of subsidence rate difference separately by sieve plate, thereby has reduced fluid resistance.
Description of drawings
Fig. 1 is the basic structure synoptic diagram of up-flow anaerobic sludge blanket in the prior art (being called for short UASB) and expanded granular sludge bed (being called for short EGSB);
Fig. 2 is the structural representation of the utility model embodiment 1.
Among the figure: 1 reactor, 2 water-ins, 3 water outlets, 4 escape pipes, 5 triphase separators, 6 sieve plates, 7 through holes, arrow is represented current or air flow line among the figure.
Embodiment
Embodiment 1: as shown in Figure 2, a kind of anaerobe sieve-tray tower, comprise reactor, reactor bottom is provided with water-in, reactor top is provided with water outlet, escape pipe, and inside reactor is provided with triphase separator, and inside reactor is provided with sieve plate, described sieve plate is horizontal positioned, between sieve plate and the reactor bottom, between sieve plate and the sieve plate certain vertical range is arranged.
Sieve plate of the present utility model is from bottom to top arranged, and the percentage of open area of sieve plate progressively increases.From bottom to top, the waste water upwelling is through sieve plate, and the regional area above sieve aperture forms jet, and mud and water form fluidisation in the fluerics; The mud of inside reactor is segmented in several different spaces because of subsidence rate difference separately by sieve plate; Sieve aperture on the described sieve plate is little and many, is evenly distributed, and makes the current uniform distribution of inside reactor on the whole.
Embodiment 2: on the basis of embodiment 1, set up water circulation pipe between water outlet and water-in, be about to part and go out water cycle.
The utility model has strengthened the inner muddy water mixed effect of anaerobic reactor.
