Abstract

The utility model relates to a water distributor of a hydrolysis reactor of an upflowing type anaerobic sludge bed, which is composed of a water inlet weir pool and grid-shaped water distributing troughs. A water inlet pipe is arranged at the center at the bottom of the water inlet weir pool. A plurality of grid-shaped water distributing troughs with the same shape and size are evenly distributed at the edge of the water inlet weir pool. A water outlet water distributing weir is arranged on the upper end of the water inlet weir pool corresponding to the center of each water distributing trough. The water distributing troughs are above the water inlet weir pool. A center at the bottom of each water distributing trough is connected with a water outlet pipe. The utility model has steady flow and even water distribution; no water distribution dead bands and dead angles are arranged in a pool of a reactor; pool capacity utilization is improved; choking points are easy to discover, and are cleaned in time.

Description

Anaerobism cloth water dispenser

The utility model relates to a kind of device of anerobic sowage biological treatment, especially for a kind of cloth water dispenser of anaerobic devices such as upflow anaerobic sludge blanket process hydrolysis reactor.

The treatment effect quality of upflow anaerobic sludge blanket process UASB or hydrolysis reactor depends on the quality of the degree of uniformity of water distribution to a great extent.Because the water distribution that reactor requires to intake should be even, the dead band can not be arranged, the dead angle, therefore, the water distribution manner of traditional reactors such as UASB is basically with perforated pipe run by gravity or water pump lifting pressure current water distribution, a dendroid water distributor promptly is set in the bottom of UASB, water is pressed into by a water-in, flow out water distribution by the outlet on the dendroid take-off pipe, this mode generally belongs to the slight drag water distribution, because it is bigger that the pond of reactor holds, the cloth water area is bigger, therefore, ensure that water distribution is evenly difficult, the utilization rate of tank volume of general reactor is all because of there being the dead band, dead angle and having a greatly reduced quality.And be difficult to find cloth water slug place, make wastewater treatment efficiency undesirable.

At above-mentioned the deficiencies in the prior art, the purpose of this utility model is the water distribution uniformity problem that solves upflow anaerobic sludge blanket process UASB, hydrolysis reactor etc., make the flow of its each cloth water spot keep uniform and stable, and when some water distributors take place to block, can in time find cleaning.Improve the utilization rate of tank volume of reactor.

The technical solution of the utility model is: this anaerobism cloth water dispenser distributes the cloth tank to form by influent weir pond and trellis, influent weir pond bottom center has a water inlet pipe, a plurality of shapes, the trellis that size is identical distribute the cloth tank to be evenly distributed on influent weir pond side, there is an effluent weir centre of corresponding each distribution cloth tank in upper end, influent weir pond, the quantity of effluent weir is identical with the quantity of distributing the cloth tank, distribute the cloth tank than influent weir pond height, distribute cloth bottom of gullet central authorities to be connected with out water distribution pipe at each.

The utility model has the advantages that:

1, Total Water can be divided into some flows equably and be assigned to each cloth water spot equably.

2, because the homogeneity of water distribution makes the flow of each cloth tank keep stable.Utilization rate of tank volume is improved at no water distribution dead band, dead angle in the pond of reactor.

3, when some cloth water spots take place to block, can direct viewing and cleaning in time on water distributor.

4, only corresponding water distributor of each water-in, stability of flow.

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

Fig. 1 is the floor map of circular anaerobism cloth water dispenser;

Fig. 2 is the I-I cross-sectional schematic of Fig. 1;

Fig. 3 is the floor map of rectangle anaerobism cloth water dispenser;

Fig. 4 is the I-I cross-sectional schematic of Fig. 3;

Fig. 5 is the II-II cross-sectional schematic of Fig. 3.

As shown in Figure 1, 2, this anaerobism cloth water dispenser is round pool shape, and its central authorities are circular influent weir pond 1, and the bottom center in influent weir pond 1 is connected with water inlet pipe 3; A plurality of sizes, the trellis that shape is identical distribute cloth tank 2 to be the outside that is evenly distributed on circular influent weir pond circumferentially, trellis distribution cloth tank 2 is 8 in the present embodiment, can optionally determine the quantity of cloth tank 2 in actual use, each trellis distributes cloth bottom of gullet central authorities to be connected with rising pipe 6, per two trellis distribute between the cloth tank and are separated by dividing plate 5, the height of dividing plate 5 is consistent with the circumferential periphery height of cloth tank 2, and the circumferential periphery height of the aspect ratio cloth tank of influent weir pond circumferential edge is low; The centre of corresponding each distribution cloth tank 2 is provided with water outlet water distribution weir 4 in the upper end of influent weir pond circumferential edge, and the quantity on water outlet water distribution weir 4 equals the quantity that trellis distributes cloth tank 2.

Certainly, above-mentioned circular influent weir pond 1 also can be Polygons, and trellis distribution cloth tank is Polygons and is arranged in the outside, influent weir pond, other shape, and structure is with last identical.

Another embodiment of the present utility model such as Fig. 3,4, shown in 5, influent weir pond 1 is a rectangle, bottom center is connected with water inlet pipe 3 in the influent weir pond, side in the influent weir pond is evenly equipped with 8 shapes, the trellis that size is identical distributes cloth tank 2, each trellis distributes the bottom center of cloth tank 2 to be connected with rising pipe 6, per two trellis distribute between the cloth tank 2 and are separated by dividing plate 5, the height of dividing plate 5 is consistent with the outer side edges height of cloth tank 2, the height of the dividing plate 7 between influent weir pond 1 and the cloth tank 2 is low than dividing plate 5, the centre of corresponding each cloth tank 2 is provided with water outlet water distribution weir 4 in dividing plate 7 upper ends, and the quantity on water outlet water distribution weir 4 equals the quantity that trellis distributes cloth tank 2.

Certainly, above-mentioned rectangle influent weir pond also can be square; Distribute the cloth tank also can be arranged on both sides square or rectangle influent weir pond.

Its principle of work roughly is: sewage enters into influent weir pond 1 by water inlet pipe 3, then by the influent weir pond equably dispense flow rate enter trellis and distribute cloth tank 2, owing to the size on water outlet water distribution weir 4, highly be identical, therefore the flow that enters into each cloth tank 2 also equates, each cloth tank 2 is separated by dividing plate 5, and volume height is identical, and the sewage that is assigned to cloth tank 2 enters into anaerobic reactor by rising pipe 6; In the bottom of reactor several water entries are set, each water entry is communicated with a rising pipe 6, accomplishes into water resistance unanimity, the flow unanimity, therefore can fully ensure the homogeneity of water inlet and the reliability of water distribution, when some water distribution pipeline generation problem, can find at any time simultaneously and in time handle.This device can adopt stainless materials such as plastics to prevent equipment corrosion.This device utilize the gross head of water inlet constant and distribute after the head of distribution cloth tank constantly satisfy the discharge that enters reactor, flow velocity is even.Simultaneously, because head is stable, when the resistance of ducting increased, the water level of the distribution weir notch of cloth water dispenser can change, and in addition, distributed the number of cloth tank to set as required, was generally 8～24.
