Abstract
Disclosed is a rotary flow soluble air device, relating to air-flotation equipment used in the sewage treatment. The device comprises a rotary flow soluble air pipe, a water pump and an air compressor. The inner wall of the rotary flow soluble air pipe is provided with one or a plurality of cavities. The outlet of each cavity is provided with a micro plate, and the inlet of each cavity is connected with the outlet of the air compressor by means of an air inlet pipe. The influent method adopts a tangential influent method. The cavity and the micro plate are arranged along the axial direction or are arranged in symmetry in the circumferential direction. With advantages of small size and lower cost, the utility model adopts the rotary flow soluble air pipe to replace a vessel tank with large size. At the same time, with the tangential influent method adopted, the raw water or the circulating water can form rotary flow inside the pipe, and effected by the micro plate, the rotary flow makes the water of same volume enwrap and dissolve more air, which can form bubbles of smaller diameters in large number, thus quite favorable for the air floatation.
Description
Technical field
The utility model relates to the airfloat equipment that uses in the sewage disposal, particularly the structure design of air dissolving system in the airfloat equipment.
Background technology
Airfloat equipment is used for sewage treatment industry, is specifically designed to suspended substance and the oil removed in the sewage.It generally is made up of airfloat equipment main frame, air dissolving system, medicine system etc., and wherein air dissolving system generally has following several form: pressure air-dissolving system, injecting dissolve gas system and drainage air dissolving system.The effect of air dissolving system all is to produce certain micro-bubble, combines with suspended substance and oil in the sewage, makes it come-up as the carrier of suspended substance and oil, reaches the purpose with water sepn.
Generally form (as shown in Figure 1) for the conventional press air dissolving system, filler 9 is housed in the dissolving body 1 by enough big dissolving body 1, water pump 6 and an air compressor machine 7.Water and air enters dissolving simultaneously by water inlet pipe 5 and inlet pipe 4 respectively, inside stops 3-5 minute, and liquid volume generally is no more than dissolving volumetrical 2/3, and internal pressure is generally 0.4mPa, and air at first is dissolved in water, forms so-called dissolved air water.Its solubleness is stressed, Temperature Influence, and the big more solubleness of pressure is big more, and temperature high-dissolvability more is low more.When dissolved air water mixed with former water, because pressure reduces, solubleness reduced, thereby discharges air in dissolved air water, made it come-up as suspended substance and oily carrier, reached the purpose with water sepn.Generally at 40-80 μ m, effect is better for bubble, is a very typical traditional air dissolving system.But the dissolving volume is very big, belongs to pressurized vessel, and cost is very high.
For injecting dissolve gas system and drainage air dissolving system reality all is to utilize the negative pressure of pump inlet to suck the part air, and forms than small bubbles through the stirring cutting of impeller, as the carrier of suspended substance and oil come-up.Bubble is belonging to dispersion air supporting generally at 100-150um aspect the molten mechanism of qi reason, because gas does not have through the dissolution process in water, is directly to cut into useful small bubbles by air pocket.The bubble diameter here is bigger, is unfavorable for air supporting; In addition, bubble quantity and bubble is also less, daf efficiency is lower, especially be not suitable for the occasion that clearance is had relatively high expectations, the water technology that effluxes such as: oil field if only be that oleaginousness is up to standard, can not guarantee the requirement of next procedure biochemical treatment, because oleaginousness can influence biochemical treatment, the emission request of last water is an overall target.
The utility model content
The purpose of this utility model provides a kind of daf efficiency height, bubble diameter is less, gas-water ratio is bigger and lower-cost eddy flow air-dissolving apparatus.
The purpose of this utility model is achieved by the following technical solution: a kind of eddy flow air-dissolving apparatus, comprise dissolving body and the water pump and the air compressor that link to each other with this body by pipeline, it is characterized in that: described dissolving body adopts the eddy flow Gas dissolving pipe, on eddy flow Gas dissolving pipe inwall, be provided with one or more cavitys, outlet at each cavity is provided with microwell plate, and the import of this cavity links to each other with the outlet of air compressor by inlet pipe; Described water inlet pipe adopts tangential water inlet pipe.
Cavity described in the utility model and microwell plate are arranged or the circumferential direction symmetric arrangement vertically.
The utility model has replaced bulky container tank with the cyclone vessel pipe, and it is little to have a volume, lower-cost advantage.Adopt tangential water intake mode simultaneously, make former water or recirculated water form the liquid stream of rotation in pipe, by the effect of microwell plate, can make with the water Relying of volume and wrap up in and dissolve more gas, the formation bubble that quantity is many, diameter is less is beneficial to air supporting very much.
Description of drawings
Fig. 1 is the structural principle synoptic diagram of traditional air dissolving system.
The structural principle synoptic diagram of the eddy flow air-dissolving apparatus that Fig. 2 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model, structure are further described:
The structural principle synoptic diagram of the eddy flow air-dissolving apparatus that Fig. 2 provides for the utility model.This device mainly comprises eddy flow Gas dissolving pipe 1, water pump 6 and air compressor 7, be provided with one or more cavitys 8 on eddy flow Gas dissolving pipe 1 inwall, be provided with microwell plate 3 in the outlet of each cavity, the import of this microwell plate links to each other with the outlet of air compressor 7 by inlet pipe 4; Described water inlet pipe 5 adopts tangential water inlet pipe.Cavity and microwell plate can evenly be arranged vertically; For the bigger eddy flow Gas dissolving pipe of diameter, also can adopt the circumferential direction symmetric arrangement.
The principle of work of this device is as follows: former water or recirculated water tangentially enter eddy flow Gas dissolving pipe 1 from water inlet pipe 5, in pipe, form the liquid stream of rotation, liquid stream is in the process of rotating along tube wall, the gas that comes out from air compressor 7 passes through inlet pipe 4, and cuts apart formation gas line through microwell plate 3, and the liquid stream of gas line and rotation meets, be cut into micro-bubble, under high pressure a part of water-soluble, another part has little time water-solublely just to be wrapped in the water by Relying, and so far dissolved air water forms.Dissolved air water enters air flotation pool rapidly to be mixed with former water, and the carrier as suspended substance or oil reaches pneumatically supported purpose.The general diameter of the bubble here is at 40-80um, moreover quantity is a lot, is beneficial to very much air supporting, is particularly suitable for the occasion that clearance is had relatively high expectations.
Eddy flow Gas dissolving pipe body 1 described in the utility model can be made with stainless weldless steel tube, and two ends are blocked with the flange group, and its volume should make the air water mixed solution stop design pressure 1.0mPa inside 10～15 seconds; At water inlet pipe 5 of end welding of eddy flow Gas dissolving pipe 1, water inlet pipe 5 should be tangent with eddy flow Gas dissolving pipe 1; At rising pipe 2 of the other end welding of eddy flow Gas dissolving pipe 1, rising pipe 2 should be in the radial direction of Gas dissolving pipe body 1; Evenly arrange several air chambers 8 at the inwall of eddy flow Gas dissolving pipe 1, be furnished with microwell plate 3 in the outlet of cavity, the import of cavity connects inlet pipe 4, and microwell plate can be used the PE material.
