Abstract

The utility model relates to a separator used for separating solid, gas and liquid three phases in an upwash type anaerobic sludge bed reactor. The utility model is assembled by rectangular modules and triangular modules. The rectangular module is in a hollow structure whose upper and lower parts are open, the middle of the rectangular module is divided into an upper drain tank and a lower gas collecting chamber by a partition board, and the upper drain tank and the lower gas collecting chamber are respectively connected with a drain pipe and a gas outlet pipe. The both sides of the upper end of the rectangular module are provided with effluent weirs, the two lateral surfaces of the effluent weirs are uniformly distributed with multilayer exhaust vents which are in staggered arrangement, each exhaust vent is communicated with the gas collecting chamber, and the exhaust vent corresponding to the same position between every two rectangular modules is provided with the triangle module. The utility model has the advantages that the utility model can be made into an assembling member and can be assembled on site, and the utility model has easy processing and manufacture and favorable multilayer separation effect.

Description

The built-up type triphase separator

The utility model relates to a kind of a kind of device that is used for anerobic sowage biological treatment,, gas solid especially for separating in the up flow anaerobic sludge blanket reactor, the triphasic separator of liquid.

In up flow anaerobic sludge blanket reactor, exist three-phase, biogas, liquid phase and solid.For the reactor of appropriate operation, the biogas that forms at digestion zone should not arrive the settling region, rises to the surface as it and will cause the water outlet muddiness, reduces precipitation and processing efficiency, and has lost biogas and the mud that is produced.In the prior art, be the whole triphase separator of prepackage in up flow anaerobic sludge blanket reactor, exist complexity is installed, change difficulty, and when reactor is big, be difficult to make corresponding triphase separator.

The purpose of this utility model is to be designed to the multistage triphase separator of piecing assembly, has solved existing in prior technology complexity is installed, and changes the deficiency of difficulty, can be applicable to the up flow anaerobic sludge blanket reactor of all size.

The technical scheme that realizes above-mentioned purpose is: a kind of built-up type triphase separator, it is characterized in that: it is assembled by rectangular module 1 and trilateral module 2, the structure of each rectangular module 1 is: empty in the rectangular module 1, the upper end, the bottom is uncovered, the centre is divided into drainage tray 7, following collection chamber 3 by dividing plate 10, dividing plate 10 is provided with the downward water shoot 5 that is communicated with drainage tray 7, and dividing plate 10 is provided with the upwards escape pipe 4 that is communicated with collection chamber 3; Both sides, upper end at rectangular module 1 are provided with effluent weir 6, are evenly equipped with the venting hole 9 of multi-layer intercrossed arrangement in the two sides of rectangular module 1, and each venting hole communicates with collection chamber 3; The venting hole 9 of corresponding same position is installed a trilateral module 2 between per two rectangular modules 1, and the lateral venting hole of the number of plies of trilateral module and quantity and each rectangular module 19 is identical.

The utility model has the advantages that it is made up of two kinds of basic modules, can on-site consolidation combination in up flow anaerobic sludge blanket reactor, changeable, adapt to not isometric reactor, easily manufactured, handling ease, cost is low, and can guarantee construction and installation quality, and maintenance, replacing are conveniently.This device adopts the stage trapping principle simultaneously, and the separation efficiency height can improve the load of reactor, guarantees effluent quality.Another advantage of this triphase separator is except gas, solid, liquid separate efficiently, makes design, the installation of up flow anaerobic sludge blanket reactor obtain simplifying significantly, and reaches the requirement of stdn and equipmentization.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of triphase separator;

Fig. 2 is the I-I view of Fig. 1;

Fig. 3 is the II-II view of Fig. 2.

As shown in Figure 1, this triphase separator is mounted in the up flow anaerobic sludge blanket reactor, and current flow (direction of arrow among the figure) from lower to upper.It is assembled by rectangular module 1 and trilateral module 2, the arrangement mode of looking actual needs rectangular module and trilateral module can be to arrange vertically, laterally or in length and breadth, thereby the quantity of rectangular module and trilateral module is to be determined by field condition in actual use, but rectangular module must not be less than two, and the trilateral module is two-layer or three layers.

The structure of rectangular module 1 as shown in Figure 1, 2, 3, it is open up and down interior hollow structure, the centre is provided with a dividing plate 10, rectangular module is divided into two portions up and down, go up and be drainage tray 7, be down collection chamber 3, dividing plate 10 is provided with the downward water shoot 5 that is communicated with last drainage tray 7, and dividing plate 10 is provided with the upwards escape pipe 4 that is communicated with following collection chamber 3; Both sides, upper end at rectangular module 1 are provided with effluent weir 6, and the number of effluent weir 6 is decided on the length of rectangular module, are evenly equipped with the venting hole 9 of multi-layer intercrossed arrangement in the two sides of rectangular module 1, and each venting hole communicates with collection chamber 3.Trilateral module 2 section forms are ∧ shape, and the venting hole of corresponding same position is installed a trilateral module between per two rectangular modules 1, thereby the lateral venting hole of the number of plies of trilateral module and quantity and each rectangular module 19 is identical.Need to prove that when rectangular module 1 was positioned at a side of triphase separator, then the outside side of this rectangular module was a tabula rasa, non air exit hole does not also have effluent weir; This can make when individual module is made.Present embodiment intermediate cam shape module is three layers and is staggered.

Principle of work of the present utility model is, current flow from lower to upper along the direction of arrow, by trilateral module 2 implement gas, (the three phase separation principle belongs to known technology to the solid, liquid three phase separation, this paper does not describe in detail), constantly the bubble that rises forms sub-air chamber 8 in ∧ shape trilateral module, bubble is quilt and water sepn in sub-air chamber 8, and corresponding precipitating attached to the suspended substance on the bubble got back to Sludge Bed, adopts three layers of staggered trilateral module to make this separation more thorough.From liquid phase, separate escaping gas (being biogas) and enter collection chamber 3 along venting hole, and by upwards escape pipe 4 discharges.Current are then upwards flowed into by effluent weir 6 by the trilateral module and go up drainage tray 7, and are discharged by following water shoot 5.
