Abstract
The utility model relates to an aeration device for aerobic biochemical treatment. The aeration device comprises the following structure units: a main air tube, a branch air tube, a support frame, a ball valve, a connecting piece, a pneumatic rotary joint, an air distribution chamber, a single-side tube type porous blade and a cable-stayed fixed frame. The micro-porous aeration device provided by the utility model not only solves the limitation of maintenance and replacement of fixed type micro-porous aeration devices but also is long in residence time of bubbles in water, so as to prevent unsaturation and saturation in a region in the traditional fixed aeration device; and therefore, the oxygen utilization rate and the theoretical power efficiency are high. Compared with a suspended chain type aeration device, the micro-porous aeration device is simple in structure; a single micro-porous aeration tube can realize the regular circular motion, so that the micro-porous aeration device has a larger aeration projection range; and meanwhile, the travel range of micropores is enlarged, and the collision among the micropores is reduced, so that an optimal hydraulic condition is created for the intensive mixing among sewage sludge, substrates and dissolved oxygen.
Description
Technical field
A kind of aerating apparatus is specially a kind of aerating apparatus for the aerobic biochemical processing.
Background technology
Aerobic biochemical is handled aeration process mainly with jet-flow aeration, and micro-pore aeration is main.Because the material development of science and technology, the micro-pore aeration technology is used increasingly extensive, shows the total transmission coefficient KLa of higher oxygen, oxygen delivery capacity and dynamic efficiency on the one hand.
Common micro-pore aeration equipment is divided into from installation form: the microporous aeration device of fixed and suspension type chain type.The replacing that the pond body could be realized spare unit need be cut off the water and empty to fixed micro-hole aerator in daily running maintenance.Suspension type chain type aerating system can realize safeguarding under the situation that does not empty the pond body and change, but is flexible material because it hangs, and makes whole aerating apparatus disordered motion in water, causes micropore to collide mutually in conjunction with and becomes big, thereby influence the utilization ratio of oxygen.
On the other hand, above-mentioned both in use the most incidental situation be: the active sludge near pond body bottom forms the dead angle easily, can not fully mix with substrate and dissolved oxygen, thereby influence the Wastewater Treated by Activated Sludge Process effect.
The utility model content
Technical problem to be solved in the utility model is: a kind of novel microporous aerating apparatus that higher coefficient of oxygen utilization is arranged again of namely can realizing safeguarding and changing under the situation that does not empty the pond body is provided.
A kind of microporous aeration device that the utility model proposes comprises following structural unit: main tracheae, segmental bronchus, bracing frame, ball valve, web member, pneumatic swivel joint, gas distributing chamber, monolateral tube-type micropore blade and tiltedly draw anchor.Main tracheae is connected with pneumatic rotating head by web member, and pneumatic rotating head is connected with gas distributing chamber by segmental bronchus, and monolateral tube-type micropore blade arrangement is fixedlyed connected with gas distributing chamber around the gas distributing chamber outer wall.
Wherein, the pneumatic rotating paddle quantity of monolateral tube-type micropore is more than 3 and 3.
Wherein, ball valve is arranged in the ingress of main tracheae, is used for the switching of control gas input.
A kind of microporous aeration device that the utility model proposes has not only solved fixed microporous aeration device and has safeguarded the limitation of changing, and gas time that stops of ducking in drink is long, avoided the regional unsaturated and supersaturation of conventional fixed aerating apparatus, therefore, coefficient of oxygen utilization and theoretical dynamic efficiency are higher.Hang the chain type aerating apparatus relatively, it is simple in structure, because the circumferential motion of its single micropore aeration pipe energy implementation rule, therefore has bigger aeration drop shadow spread, increase the stroke of micropore simultaneously, and the collision between the minimizing micropore, being mud, optimal hydraulic conditions is created in the abundant mixing between substrate and the dissolved oxygen three.

Embodiment
The utility model is described in further detail below in conjunction with specific embodiment of the utility model.
In this preferred embodiment of the present utility model, embodiment thinks to be that a bio-aeration pool configuration microporous aeration device is example.
As shown in Figure 1, the microporous aeration device in this pond comprises: main tracheae 1, bracing frame, ball valve 8, web member 2, pneumatic swivel joint 3, gas distributing chamber 6, monolateral tube-type micropore blade 7 (can regulate jet angle) and tiltedly draw anchor 5.Main tracheae 1 is arranged in bio-aeration pool liquid level top, and bracing frame is strip, and the upper end is by buckle and 1 clamping of main tracheae, and the lower end is fixed at the bottom of the bio-aeration pool pond.The parts that bracing frame supports main tracheae 1 thus and is connected with main tracheae 1.
Main tracheae 1 is connected with pneumatic swivel joint 3 by web member 2, and in this specific embodiment of the present utility model, web member 2 is the threaded connector 2 that a bore and main tracheae 1 adapt.Ball valve 8 is installed on the inlet mouth of main tracheae 1, is used for the switching of the main tracheae 1 of control.
Pneumatic swivel joint 3 one ends are connected with main tracheae 1 by threaded connector 2, and the other end is connected with segmental bronchus 4.Pneumatic swivel joint 3 is subjected to the gaseous tension effect in the main tracheae 1, and an end that is connected with segmental bronchus 4 drives segmental bronchus 4 and rotates.
Segmental bronchus 4 is fixedlyed connected with gas distributing chamber 6, and in this specific embodiment of the present utility model, segmental bronchus 4 and gas distributing chamber 6 are fixedlyed connected by flange-interface.
Monolateral tube-type micropore blade 7 mutually at an angle equidistant placement around gas distributing chamber 6 outer walls, fixedly connected with gas distributing chamber 6, and the junction is hollow, is used for gas distributing chamber 6 and carries other to monolateral tube-type micropore blade 7.In this specific embodiment of the present utility model, 3 monolateral tube-type micropore blades 7 are connected with the gas distribution by the hickey of hollow.Tiltedly draw anchor 5 one ends to be connected with gas distributing chamber 6 upper ends, an end is connected with monolateral tube-type micropore blade 7.
Because pneumatic swivel joint 3 drives segmental bronchus 4 and rotates, so all rotate with the fixedly connected gas distributing chamber 6 of segmental bronchus 4 and the monolateral tube-type micropore blade 7 that is connected with gas distributing chamber 6, the sense of rotation of monolateral tube-type micropore blade 7 and aeration direction are as shown in Figure 2.
As shown in Figure 3, a kind of novel microporous aerating apparatus that the utility model proposes only adopts 108 micropore aeration pipes just to realize whole bio-aeration pool uniform aeration, and bubble pathway length lengthens, be conducive to improve coefficient of oxygen utilization, promote active sludge simultaneously, combination treatment effect between substrate and the dissolved oxygen three.
