Description

A kind of activated sludge reaction device

Technical field

This utility model relates to sludge treatment device, specifically a kind of activated sludge reaction device.

Background technology

The by-product mud of sanitary sewage disposal is the biggest to the destruction of environment, it is therefore desirable to enter The process of one step.And during Treatment of Sludge, prior art exists mud is kept water body In directly process method.At this time, a lot of compositions in mud all can gradually decompose, release In water body, the concentration of reaction system is caused to uprise.At this moment, it is necessary to floating impurity is entered Row separates, in order to avoid producing too much foam.Meanwhile, many it is contaminated with in the middle of general mud not Same impurity, wherein having significant portion is fluid mixture, and these fluid mixture are in mud Mix layer by layer, it is very difficult to obtain efficient, high-quality separation, it is difficult to preferably process mud, Meanwhile, bring bad impact also can to the operation of processing equipment.

Utility model content

In order to overcome the deficiencies in the prior art, this utility model provides a kind of activated sludge reaction dress Putting, its floating impurity (oils and fats etc.) separation efficiency is high, and effective, makes Treatment of Sludge set The trouble-free operation of standby energy.

This utility model solves its technical problem and be the technical scheme is that

A kind of activated sludge reaction device, it is characterised in that: including casing, described casing is arranged The floating impurity catcher higher than sludge reaction liquid level, described floating impurity catcher lower end is had to set It is equipped with impurity delivery pipe, in described casing, is additionally provided with sludge outlet, and at least one gas transmission / liquid pipe, described defeated gas/liquid pipe is provided with venthole.

As the improvement of technique scheme, described floating impurity catcher is the taper of band dentation Funnel, described impurity delivery pipe one end connects floating impurity catcher bottom, and the other end is connected to Outside described casing, for discharge impurities.

As the further improvement of technique scheme, in described casing, it is additionally provided with the removal of foam Device, it is positioned at above described floating impurity catcher.

Further, described froth killer is rotatable stirring paddle.

Further, described froth killer is the spray thrower that can spray defoamer.

As the further improvement of technique scheme, described defeated gas/liquid pipe is arranged in the form of a ring Casing inner bottom part, is distributed multiple venthole on described defeated gas/liquid pipe.

Further, in embodiments more of the present utility model, comprise the defeated gas/liquid of 2-4 bar Pipe, and equidistant arrangement is at described box bottom, the opening direction of described defeated gas/liquid pipe makes dirt Mud reactant liquor forms vortex.

The beneficial effects of the utility model are: the profit in mud can will effectively be mixed by this device Closing impurity etc. to separate, its separation efficiency is high, and good separating effect has good use valency Value；This device can effectively eliminate the bubble produced in course of reaction, prevents overflow；This device Defeated gas/liquid pipe can make the gas/liquid being mixed into be sufficiently mixed with sludge reaction liquid, it is achieved the joint of the energy Save.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Fig. 1 is the inner mounting structure schematic diagram of one embodiment of this utility model；

Fig. 2 is the inner mounting structure schematic diagram of another embodiment of this utility model.

Detailed description of the invention

With reference to Fig. 1, a kind of activated sludge reaction device of the present utility model, including for mud Processing the casing 1 of reaction, its top is provided with opening or passage.Described casing 1 internal upper part, Opening or passage are arranged with the floating impurity catcher 2 higher than sludge reaction liquid level, described Floating impurity catcher 2 is provided with impurity delivery pipe 21；It is additionally provided with mud in casing 1 to go out Mouth 22 and defeated gas/liquid pipe 3.When sludge outlet 22 connects other pipelines, it is also possible to valve is set Door (not shown), to control the delivery flow of mud, keeps the reaction liquid level in casing 1. As it is shown in figure 1, described defeated gas/liquid pipe 3 is arranged in bottom casing 1 in the form of a ring, it is arranged Give vent to anger (water) hole.In embodiments more of the present utility model, defeated gas/liquid pipe 3 is permissible It is arranged in bottom casing 1 for multiple concentric circles.No matter with which kind of shape, mode arrange (as Shown in Fig. 2), its purpose is all uniform gas distribution or liquid as far as possible.Defeated gas/liquid pipe 3 By giving vent to anger, (water) hole feeds gas (liquid) body in mud, and gas is by oil water mixture gradually Push to Sludge Surface, thus separated by floating impurity catcher 2, discharge from delivery pipe 21. In embodiments more of the present utility model, comprise 2-4 bar defeated gas/liquid pipe (as shown in Figure 2 It is 2 defeated gas/liquid pipes), and equidistant arrangement is at described box bottom, described defeated gas/liquid pipe Opening direction makes sludge reaction liquid form vortex.

As the improvement of above-mentioned embodiment, described floating impurity catcher 2 is the cone of band dentation Shape funnel, described impurity delivery pipe 21 one end connects floating impurity catcher 2 bottom, another End is connected to described casing 1 outside drain impurity.Set on floating impurity catcher 2 edge of opening It is equipped with flange, in dentation.Oil mixing with water impurity constantly rises under gas effect, directly arrives Floating impurity catcher 2 opening just naturally falls in conical hopper, discharges from delivery pipe 21, Very quick, simple.On the other hand, the height of liquid level is by setting on control sludge outlet 22 The valve put is to regulate flow.

As the further improvement of above-mentioned embodiment, in described casing 1, it is additionally provided with foam Canceller 4, it is positioned at above floating impurity catcher 2.Described froth killer 4 is for revolving The stirring paddle turned and/or the spray thrower that defoamer can be sprayed, thus can quickly eliminate too much bubble Foam, it is to avoid overflow.

Described defeated gas/liquid pipe 3 is provided with at least one, and defeated gas/liquid pipe 3 is in casing 1 inner bottom Portion's bending extension, and defeated gas/liquid pipe 3 is distributed the venthole of several diverse location, thus really Protect gas and can promote profit from mud equably.

The above, better embodiment the most of the present utility model, but this utility model It is not limited to above-described embodiment, as long as it reaches this utility model with any same or similar means Technique effect, within all should falling into protection domain of the present utility model.
