The oil removal percentage is more than 99%, and the heavy metal removal percentage is more than 96%. The SS removal rate is more than 99.5, the COD removal percentage is more than 96%, and the PH is neutral.

Description

Emulsification sewage purification apparatus

The utility model belongs to sewage disposal device, particularly the device of purifying and emulsifying sewage.

Metal cutting in the modern industry production, rolling metal and the metal technology of reeling off raw silk from cocoons all need use emulsion as cooling, lubricant in the processing.This water soluble emulsifier is prepared according to processing requirement, and the oil content of wastewater that is formed by it is up to 2.0 * 10 ⁴Mg/litre, chemical oxygen demand is up to 5.0 * 10 ⁴Mg/litre.Wherein also have heavy metal ion and other pollution substance.This sewage can serious environment pollution, and not treated is not allow to enter water drain.But profit is blindly dated and is combined together in the emulsification sewage, and chemical stability is strong, is the most unmanageable a kind of in the oily(waste)water.Some treatment facilities have appearred on the domestic and international market in recent years, as adopting the equipment of gravity method and coarse method, and devices such as solvent extractions, reverse osmosis, filtration, and they or operation more complicated or expense height, and effect is all undesirable.

The purpose of this utility model provide a kind of simple in structure, processing efficiency is high, emulsification waste disposal plant satisfactory for result.

The purpose of this utility model is achieved in that whole set comprises emulsification sewage tank, sump pump and flocculation reaction jar, its main points are that its flocculation reaction jar is a flocculation reaction equipment efficiently, be characterized in: the flocculation reaction jar is an opening tank body, the interior middle and upper part of jar is provided with taper deslagging cover and is connected with annular sieve plate, the jar inner chamber is divided into two portions up and down, top is the deslagging part, the bottom is divided into reactive moieties, reactive moieties is chosen suitable blade diameter length ratio, and make up and down and to be taper, the middle part is a cylinder, the global approximation sphere, help the carrying out that react, at the reactive moieties middle part electric mixer is housed also, the star flocculation reaction accelerator that is communicated with inlet pipe particularly is housed in the bottom, it is by the star gas distributor and be connected on porous polyethylene on each joint of divider, and microfiltration tube is formed.

During work, sewage is squeezed into the flocculation jar through pump, add coagulating agent in jar, mix under the effect of electric mixer and carry out flocculation reaction, open air inlet control pipe valve simultaneously, gas enters the flocculation reaction accelerator under certain pressure, and emit a large amount of small bubbles by porous polyethylene microporous pipe, play pneumatic stirring action, accelerated reaction, and the floss that flocculation reaction is produced quickens to rise.Clarifying contaminated liquids.Open the premium on currency pipe valve at last, with the premium on currency method cotton-shaped slag thing is overflowed from taper deslagging cover, through the water that it is unnecessary that sieve plate leaks down, floss is discharged from slag-drip opening, and the water purification in jar reaches water white transparency.Usual method contains oil removing rate only 70%, and this device can surpass 99%.

The utility model major advantage compared with prior art shows as:

1, because the shape and the structure of flocculation jar help flocculation reaction, owing to be provided with the effect of flocculation reaction accelerator, cause favourable dynamic condition, and emit a large amount of micro-bubbles again, can be mixed in the throw out and be attached on the flocs unit, thereby quicken the formation of throw out and the speed of come-up.

2, owing in the jar taper deslagging cover is arranged, can reduce the premium on currency amount of premium on currency deslagging, floss is concentrated in rising, thereby increase the intensity of throw out, help thorough deslagging.

3, be provided with the premium on currency pipe valve, adopt the premium on currency method for discharging residue, do not destroy throw out, guarantee that deslagging is thorough, and the wadding slag of being discharged at first passes through sieve plate, redundant moisture is back in the jar, has reduced the water content of deslagging.

4, the flocculation reaction accelerator has also increased the oxygen level in the sewage when emitting a large amount of bubbles, and oxygen can carry out oxidation to other impurity in the sewage, has promoted the water purification degree.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of flocculation accelerator;

Fig. 3 is the vertical view of Fig. 2.

With reference to the accompanying drawings: 1-emulsification sewage tank among Fig. 1; The 2-sump pump; 3-premium on currency pipe valve; 4-flocculation reaction accelerator; 5-inspects mirror; The 6-electric mixer; 7-scum pipe, valve; 8-backwater sieve plate; The 9-motor; The 10-tank body; 11-taper deslagging cover; 12 ,-return water pipe, valve; 13-inlet pipe, valve; 14-offlet, valve; 15-water purification delivery pipe, valve.

Emulsification sewage is stored in the tank 1, through pump 2, and pipe 3, enter tank body 10, tank body 10 circles, suitable for reading has motor 9 on angle steel, drive agitator 6, scum pipe 7 is arranged outside the tank body 10, it is the side on the upper side, and return water pipe 12 is at the middle part, and inlet pipe 13 is in the bottom, inlet pipe 13 is led to the joint 43 of flocculation reaction accelerator 4, and the bottom also has offlet 14 and water purification delivery pipe 15.Pipeline is a usual method with connecting of tank body 10.There are for 6 times taper deslagging cover 11 and sieve plate 8 that tank body 10 is divided into two ones up and down at slag-drip opening.And return water pipe 12 is communicated with the lower section sieve plate 8 with the tank body of taper deslagging cover below 11.

During work, sewage is by pump 2, pipe 3 enters tank body 10, add coagulating agent in the tank body, start electric mixer, air inlet body pipe valve 13 is opened in the beginning flocculation reaction simultaneously, and adjusts suitable pressed gas by flocculation, the gas distributor 42 of reaction accelerator and polyethylene microporous pipe 41, form a large amount of bubbles, promote flocculation reaction to quicken, the cotton-shaped slag that reaction forms floats on the surface, open the valve of riser pipe 3 and inwardly annotate clear water, make scum silica frost overflow the suitable for reading of taper deslagging cover 11, unnecessary water leaks down from sieve plate 8, and scum silica frost is discharged from slag-drip opening 7.Open return water pipe, valve 12, sieve plate 8 following current return tank body.Water after the processing flows out through the water purification delivery pipe.Through the test decontamination effect improving is oil removal rate more than 99%, and heavy metal removing rate is more than 96%; The COD clearance is more than 96%; The SS clearance is more than 99.5%, PH neutrality, and water colorless is transparent.

This device can be designed to plurality of specifications as required, and per hour the amount of disposing of sewage is by 1m ³To 10m ³
