Abstract

An inclined plate type mechanical agitating clarifier comprises a first reaction chamber, a second reaction chamber, a separation chamber and a mud chamber, wherein an inclined plate area arranged in the separation chamber consists of a plurality of inclined plates which are parallel mutually and disposed obliquely. Besides, the inclined plates of the inclined plate area are made of glass fiber reinforced plastics or stainless steels or PP. The arrangement of the inclined plate area provides a platform for a large number of micro suspension particles in treating liquid to collide and contact mutually, and large particles can be formed by aids of adsorption and charge neutrality, deposition immeshing and the like, thereby increasing gravity, strengthening deposition effect, increasing solid and liquid separation effect obviously and stabilizing treatment effect. Further, due to the inclined plate area, clarifier tank volume and floor area are reduced.

Description

Ramp type mechanical agitation clarifier

Technical field

The utility model relates to a kind of clarifier, specifically, relates to a kind of ramp type mechanical agitation clarifier.

Background technology

Accelerator claims accelerating purifying pool again, in water treatment system, widely apply, it is the ideal equipment of Separation of Solid and Liquid, the circulation of finishing water and medicament mixing, reaction and body refuse by the mechanical agitation of the inner specific structural design in pond and supporting mixer, mud scraper with contact coacervation process and form bigger floccule body, carry out precipitate and separate by the separation chamber, excess sludge is scraped to collect to mud-removing bucket by mud scraper and is discharged by hydrostatic pressure.

Accelerator has experienced years of development, has had the type selecting equipment of each water treatment amount section, has obtained a large amount of utilizations in industries such as electric power, municipal administration, petrochemical industry, chemical industry.The mechanical agitation clarifier of China's use at present mainly contains two kinds, a kind of is homemade type mechanical agitation clarifier (as shown in Figure 1), another kind is the introduction type mechanical agitation clarifier (as shown in Figure 2) from Britain P.W.T company, two kinds of clarifiers all are made up of several parts such as first reative cell, second reative cell, separation chamber, slurry chambers, and these two kinds of products are very ripe through utilization for many years.Certainly, in order keeping on improving, to put into practice and sum up through a large amount of utilizations, the clarifier of these two kinds of technology all comes with some shortcomings, and by the improvement of some local techniques, can obtain better effect.

Current society, the soil is more and more in short supply, how reasonably to distribute, use the soil to become the emphasis that country, society, enterprise must consider, save the area and become the design principle of every field, and all there is the shortcoming bulky, that floor space is wide in two kinds of clarifiers that China uses at present, are unfavorable for its development.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of floor space is little, the ramp type mechanical agitation clarifier of good effect of separating solid from liquid.

The technical scheme that realizes above-mentioned purpose is: a kind of ramp type mechanical agitation clarifier, comprise first reative cell, second reative cell, separation chamber and slurry chamber, be provided with the swash plate district in the described separation chamber, this swash plate district is placed by a plurality of inclinations and the swash plate that is parallel to each other constitutes.

The material of the swash plate in described swash plate district is glass steel or stainless steel or PP.

After adopting technique scheme, be provided with the swash plate district in the separation chamber of clarifier, the swash plate district tilt to be placed and the swash plate that is parallel to each other constitutes by certain angle by a plurality of, solidliquid mixture enters the swash plate district by the bottom, separation chamber, and according to " shallow-layer principle ", small suspended particulate will assemble, collide at this, form big particulate matter, sink, the solid-liquid contact area increases greatly, and solid-liquid separation effect obviously improves.

Swash plate material variation in the swash plate district has multiple choices such as fiberglass, stainless steel, PP, and its swash plate spacing (inclined tube circular section size) also has multiple choices, and the length of swash plate can be customized.So, according to the water quality characteristics and the fluid requirement of treatment fluid, can select the most rational swash plate parameter for use, improve its economy and practicality.

The treatment effect aspect, according to sedimentation theory, suspended particulate small in the pending liquid is little because of its deadweight, being easy to be taken out of by current influences the water outlet effect, and the setting in swash plate district, for small suspended particulates a large amount of in the treatment fluid provides the platform that runs foul of each other, contacts, utilize absorption charge neutrality, precipitation net to catch etc. and form big particle, deadweight increases, and sedimentation effect is strengthened, and treatment effect is stable.

Innovative point of the present utility model is as follows:

1. carry out the body structure design of rational pond in the clarifier, the zone that compartition makes new advances---swash plate district;

2. the establishment in swash plate district has reduced pond appearance, occupation of land, has improved treatment effect;

3. the introducing of " shallow-layer theory " makes the scope of application of mechanical agitation clarifier wider, and the treatment fluid that the high solid-liquid of some viscositys is difficult to separate also can be considered this device;

4. diversified swash plate: swash plate length and spacing are adjustable, have increased the flexibility of design, and optimal design has improved the economy of general structure.

Fig. 2 is the schematic diagram of the introduction type mechanical agitation clarifier before improving;

Fig. 3 is a schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 3, a kind of ramp type mechanical agitation clarifier comprises first reative cell 1, second reative cell 2, separation chamber 3 and slurry chamber 4, is provided with swash plate district 5 in the described separation chamber 3, and this swash plate district 5 is placed by a plurality of inclinations and the swash plate that is parallel to each other constitutes.

The material of the swash plate in described swash plate district 5 is glass steel or stainless steel or PP.PP is exactly a polypropylene.

Operation principle of the present utility model is as follows:

Solidliquid mixture enters swash plate district 5 by 3 bottoms, separation chamber, and according to " shallow-layer principle ", small suspended particulate will assemble, collide at this, form big particulate matter, sink, and the solid-liquid contact area increases greatly, and separating effect obviously improves.

According to formula:

T=(h1+h2) * 60/q (wherein h1, the h2 swash plate district top depth of water, swash plate district height, q are the design surface load, and t is the time of staying)

Thus formula as seen, design surface load increases by 1 times, then the time of staying reduces one times.

And the computing formula of the effective water surface area F of pond body is:

F=Q/ (q * 0.91) (Q is a design discharge in the formula, and q is the design surface load, and 0.91 is swash plate district area utilization factor)

Thus formula as seen, design surface load is enhanced about more than once, then body effective water surface area in pond is dwindled more than one times, the floor space of pond body directly is reflected on the effective water surface area of pond body, so, pond body floor space can be dwindled more than 1 times, and the volume of pond body also just greatly reduces.

Claims

1. ramp type mechanical agitation clarifier, comprise first reative cell (1), second reative cell (2), separation chamber (3) and slurry chamber (4), it is characterized in that: be provided with swash plate district (5) in described separation chamber (3), this swash plate district (5) is placed by a plurality of inclinations and the swash plate that is parallel to each other constitutes.
