Abstract

The utility model relates to an integral high-efficient precipitation and concentration device, belonging to the processing equipment of solid-liquid separation for feedwater and sewerage. The utility model is provided with a mixer, a V-shaped groove plate, a forced guiding mud pipe, a forced outlet pipe, a settling chamber and a concentrating chamber. The measures of the V-shaped groove plate and forced soil discharging are used to make the precipitation efficiency enhanced. The problem of difficult soil discharging in a multi-ply sedimentation tank is solved. The utility model can be widely used for any solid-liquid separation of water treatment, in particular for the solid-liquid separation of feedwater or sewage of raw water with high concentration.

Description

Integral high-efficient precipitation and concentration device

The integrated high-efficiency concentrating unit belongs to the solid-liquid separating equipment of feedwater and sewage disposal, can be used for the solid-liquid separation of any water treatment, is specially adapted to the solid-liquid separation of the feedwater or the sewage disposal of the former water of high density.

The solid-liquid separation of existing tap water and sewage disposal, the intermediate processings that adopt wherein have rectangular sedimentation tank and vertical sedimentation basin more, and more advanced swash plate and tube settler are also arranged, they are all low than multi-tiered plate settling tank effect, and have the problem of spoil disposal difficulty.

The purpose of this utility model just provides a kind of dull and stereotyped multilayer settler, and it is than existing like product efficient height, less investment, instant effect.

The utility model is realized in the following manner.

Theory and practice proves, the deposition efficiency of solid-liquid separation: E=(Au ₀In the formula of)/(Q), E ₂Deposition efficiency (%), Q: flow (m ³/ time), U ₀: sedimentation speed (mm/ second), A: desilting area (m ²).Can improve the best approach of deposition efficiency E, strengthen desilting area exactly.The utility model has designed a kind of V-type frid, and takes to force shore pipe, and mud concentrates the measure of grade, has reached and has both improved settling efficiency, solves the difficulty of spoil disposal again.

Be illustrated below in conjunction with an embodiment.

Fig. 1. be integrated high-efficiency precipitation concentrating unit structure iron.

(14) are integrated high-efficiency precipitation concentrating unit pond bodies among the figure, and the pond body has header (7) in the middle of the upper end, is connected with (11) ten layers of eight V-type frids around it, parallel placement, and V-type frid shape is seen Fig. 3.The V-type frid that multilayer is parallel is connected into one, has played the fixed action of an end by in the middle of the frid notch 50-100mm to force mud guiding tube (5) to pass every, and having formed one is the similar Polygons cylinder at center with header (7).The space that it and pond body (14) shell form is distributing water room (3), and the alternate place of adjacent two V-type frids (11) is settling chamber (4), and it communicates with header (7).Force to have into mud hole (13) on the mud guiding tube (5).The pond body is divided into two layers and all is tapered, and the upper strata is reaction chamber (2), and lower floor is mud concentration compartments (6).The spiral type mixing tank (1) of this example can be contained in the middle of the reaction chamber (2), also can be located at externally separately, taps into water pipe (18), and former water enters water inlet pipe (18) back to be mixed in mixing tank.Force outlet pipe (9) to be installed on pond body (14) shell, distributing water room (3) is connected in its upper end, and mud concentration compartments (6) is connected in the lower end, forces rising pipe that control aquifer yield valve (19) is housed.One stabilier (12) is arranged in the mud concentration compartments, be one cylindric, ligation chamber, upper end (2) the awl end,, lower end and concentration compartments (3) are bored the end and are stayed a slit, have limbers (20) on the stabilier, can avoid interference the pressure water outlet.Shore pipe (10) is discharged the mud of concentration compartments.Body top, pond envelope is stayed a space with Chi Gai (15) between the two, with the water vapor bubbles of discharging in the water treatment procedure, suspended substance will concentrate in this zone, and Chi Gai (15) opens at the edge row's bubble pipe (16), in order to drainage water, bubble, suspended substance.Chi Gai (15) adorns a vent valve (17) on the top.

Constituting each component materials of integrated high-efficiency precipitation concentrating unit, can be metallic substance, also can be plastics or glass-reinforced plastic material.

Fig. 2 is an integrated high-efficiency precipitation concentrating unit vertical view.

Fig. 3 is the V-type frid.

The working process of this device:

Former water is from the spiral type mixing tank (1) of water inlet pipe (8) through selecting for use, be mixed into reaction chamber (2), water flow velocity slows down, slowly rise to distributing water room (3), pass through multilayer V-type frid again to the settling chamber (4), sludge settling is on V-type frid (11) in the water, and mud is transported to concentration compartments (6) by forcing the mud hole (13) of advancing on the mud guiding tube (5) to enter pressure mud guiding tube (5).Spissated mud is discharged by shore pipe (10).The mud transfer rate of forcing mud guiding tube is by forcing the valve (19) on the rising pipe (9) to be controlled.Clear water footpath header (7) in the settling chamber (4) is drained by rising pipe (8).

V-type frid optimum size in the utility model design:

Flute length A:300-500mm

The high C:60-100mm of groove

Slot opening B:230-300mm

The spacing that is arranged in parallel of two V-type grooves is 60-100mm

Force the diameter D:25-32mm of mud guiding tube

The economic technology of integrated high-efficiency precipitation concentrating unit and old-fashioned sloping plate deposition is an example to handle water yield 500m/ day relatively:
