Abstract

The utility model belongs to the technical field of environment protection, and discloses a device for purifying sewage. The purifying device consists of a plurality of purifying tanks. The water inlet pipe has a bent head, and rotates the liquid in the purifying tanks to produce vortexes. According to the Han Principle invented by the designer of the utility model, suspension and precipitate are respectively concentrated at the upper centers and lower centers of the vortexes and then discharged through a suspension discharge pipe and a precipitate discharge pipe; the purifying tanks of each grade are communicated via countersunk overflow pipes, and purified water is discharged though a water discharge pipe. Employing Han Principle, the utility model improves the purification effect, and can be widely applied to chemical engineering or other industries for purification of physically polluted water.

Description

Effluent treatment plant

Technical field

The utility model belongs to environmental technology field, is a kind of device that is used for purifying waste water, and can be widely used in physical pollution water purification in chemical industry and other industries.

Technical background

In the existing sewage tripping device, a kind of device that is called oil trap is arranged, comparatively common in oil depot, effect is separating of oil comes out that will be mixed in the water, principle of work such as Fig. 1, whole device is made up of elementary, secondary, third stage purification tank, the primary purifying groove is equipped with water inlet pipe by top, and inlet valve control flooding quantity is housed, third stage purification tank by the bottom rising pipe is housed and flowing water Valve control discharges water, between primary purifying groove and the secondary stage purified groove, between secondary stage purified groove and the third stage purification tank, connected entrance is all arranged near on the wall of bottom.When the water that is mixed with oil enters the primary purifying groove through inlet valve and water inlet pipe, oil in the water, because of water insoluble and proportion less than water, oil just floats over just on the water purifying water surface, first water purification flows into the secondary stage purified groove through connected entrance, in the secondary stage purified groove, residual oil floats on time water purifying water surface equally, and inferior water purification flows into third stage purification tank through connected entrance, in third stage purification tank, the residual oil of minute quantity floats on the water surface of purifying waste water equally, purifies waste water and discharges through rising pipe and flowing water Valve.During work, inlet valve is based on dominant discharge, and flowing water Valve is based on the control liquid level.

Summary of the invention

The utility model is the improvement to above-mentioned oil trap device.Effluent treatment plant of the present utility model is made up of several purification tanks, inlet valve (1) and water inlet pipe (2) are housed on primary purifying groove (3), rising pipe (7) and flowing water Valve (8) are housed on final stage purification tank (6), suspended substance vent pipe (10) all is housed on each purification tank sidewall, bottom center is equipped with throw out vent pipe (11), is equipped with between the purification tanks at different levels to immerse oneself in upflow tube (4).

Of the present utility model being characterised in that, the water inlet pipe (2) on the primary purifying groove (3) extend into the middle part of liquid level downwards and turn 90 degree curved (as K to shown in the view).Suspended substance vent pipe (10) is higher than upflow tube (4), and adjustable height, and the mouth of pipe is positioned at purification tank central authorities.Immersing oneself in the discrepancy end of upflow tube (4) is positioned at the mid-way of liquid level, enters that the water side of back first class purification groove is the same with water inlet pipe (2) to have 90 to spend elbows.The mouth of pipe of rising pipe (7) also is positioned at the mid-way of liquid level.

During work, need the influx of the muddy water of purification by inlet valve (1) control; According to each purification tank floating impurity what, control blowdown flow rate with the valve (9) on the suspended substance vent pipe (10); According to precipitated impurities what, arrange the throw out amount with the control of the valve (12) on the throw out vent pipe (11).

Principle of work of the present utility model is to use that proportion can float the water surface less than the impurity of water and outside the principle that proportion can sink under water greater than the impurity of water, the Han Shi principle of the design people's proposition.

The Han Shi principle is to say: liquid in rotation produces vortex, and under the acting in conjunction of buoyancy and liquid-flow, floating matter concentrates on center on the vortex, and throw out concentrates on center under the vortex.

Fill liquid in the cylindrical vessel as shown in Figure 3, when liquid when cylinder axis rotates, just produced vortex.This moment, the flow direction V1 of liquid rotated around the EF axle; Also having the movement locus of V2 in addition is A → E → O → G → A; The movement locus of V3 is B → E → O → H → B; The movement locus of V4 is C → F → O → G → O; The movement locus of V5 is D → F → O → H → D; The mass motion of liquid then is respectively V1+V2 in the groove, V1+V3, V1+V4, the vector of V1+V5 and.

Fluid always flows to the low place of pressure from the high place of pressure, and therefore the flow direction from water proves that the pressure at vortex edge is higher than the pressure of vortex core.The direction of motion of suspended substance is exactly the direction of buoyancy, always pushes suspended substance to low-tension side from the high-tension side, and last conclusion is that the mobilization force and the buoyancy of liquid focuses on central point E on the vortex with suspended substance.

Throw out is sunken to liquid bottom because of proportion greater than the proportion of liquid, under the effect of V4 and V5 liquid flow power, shifts throw out onto the center of bottom land, i.e. F point below.

Working process of the present utility model is such: sewage enters the middle part of primary purifying groove (3) through inlet valve (1) and water inlet pipe (2), because of there are 90 degree elbows the water side of water inlet pipe, the current of going into groove are that level is effusive, make the water rotation in the groove, form vortex, proportion concentrates on the vortex near the center less than the impurity of water, and proportion concentrates under the vortex near the center greater than the impurity of water.Liquid level raises and rotation, when liquid level rises to the last overflow port of upflow tube, first water purification in the primary purifying groove (3) overflows into the middle part of secondary stage purified groove (5) through upflow tube (4), liquid level raises and rotation in the secondary stage purified groove (5), when liquid level rises to the last overflow port of upflow tube (4), inferior water purification in the secondary stage purified groove (5) overflows into the middle part of next stage purification tank through upflow tube (4), liquid level raises and rotation in the next stage purification tank, by that analogy, clean water in the penultimate stage purification tank overflows in the final stage purification tank (6) through upflow tube (4), and the clean water that purifies is discharged through water shoot (7) and water discharging valve (8) again.
