Abstract
The utility model relates to a free level air dissolver, belonging to the improvement of a sewage treating device for environmental protection. The utility model comprises an air dissolving tank, a reflux pump, and an air compressor. The air inlet of the air dissolving tank is connected with an air distributing pipe on which a plurality of small holes for distributing the air are arranged. When the free level air dissolver works, the air distributing pipe is dipped in water. Compressed air input by an air compressor is led in the water through the air distributing pipe. Because the self hydraulic pressure of the reflux pump is considered as a pressure source for dissolving air, the water can be at a free liquid level, most of control units are omitted. The utility model which is suitable for treatment of industrial waste water and domestic sewage for paper making, and printing and dyeing for textile, etc. Has the advantages of greatly simplified operation process, enhancement of the water yield of a unit area, and good effect of the dissolving air.
Description
The utility model relates to a kind of air-dissolving apparatus that uses when utilizing the air supporting principle to dispose of sewage, and belongs to the improvement to the environment protection sewage treatment facility.
Will use air-dissolving apparatus when disposing of sewage with the air supporting principle, its effect is under certain pressure, makes an amount of air and partial reflux water form saturated dissolved gas in dissolving and cuts out body, feeds then in the sewage lagoon in order to remove the impurity dirt.Present common employing be control liquid-level type air-dissolving apparatus, it is that pressure source carries out molten gas work with the pressurized air that accounts for jar internal volume 2/3, its groundwork process is to inject the pressurized air of certain pressure earlier in jar, again with reflux pump water filling in jar (from top to bottom), the distributive pipe of flowing through, water distributing tray, filler, enter the bottom behind the grid, after conduit enters sewage lagoon discharges, must guarantee in the dissolving that in this working process the fixed pressure of weighing apparatus is gentle, water volume ratio (water level that is water must be constant), so must constantly replenish air in certain amount and water, in actual applications, by each valve, under meter, the repeatable operation of liquidometer is regulated and is kept liquid level, air pressure, pump pressure, the balance of flow, complicated operating process is loaded down with trivial details, though some has adopted automation installation to control liquid level at present, brought complex structure simultaneously again, the cost height, problems such as inconvenient maintenance.
Task of the present utility model provides a kind of designs simplification, the effective free liquid level air-dissolving apparatus of easy to operate, molten gas.
The utility model composition includes dissolving (1), reflux pump (2) and air compressor (3), dissolving (1) fuses with reflux pump (2), air compressor machine (3) by hydraulic pipe (4), pneumatic tube (5), and dissolving (1) bottom is provided with rising pipe (103).Characteristics of the present utility model are that the inlet mouth (101) of dissolving (1) is connected with gas distribution pipe (102), have many apertures (102a) on it in order to delivery air, gas distribution pipe during work (102) is immersed in the water, the pressurized air of air compressor machine (3) input evenly enters in the water by the gas distribution aperture of gas distribution pipe (102), under the original tape pressure of water, be dissolved in water, because when work, self hydraulic pressure with reflux pump was pressure source, water can be free liquid level, be different from the mode of dependence pressurized air in the past greatly as pressure source, so the volume of air in the dissolving (1) and the volume of water need not to remake strict control, can save the liquidometer that is used to control liquid level, under meter and automatization control device, simplify the structure greatly and operating process, thereby reached the purpose of this utility model.
When concrete the use, can be provided with gas holder (6) between air compressor machine (3) and the dissolving (1), so that operation and saving electric power.For guaranteeing safety, dissolving (1) top is provided with safety plug (7) in addition.
Working method of the present utility model is as follows: at first start air compressor machine (3), to gas holder (6) gas injection to certain pressure, start reflux pump (2) water filling in dissolving (1), and adjust on the water pipe (103) outlet valve to jar internal pressure a little less than gas holder (6), open the intake valve gas injection in jar continuously on the pneumatic tube (5), after treating that air dissolving system is stable, the water of rising pipe (103) can be introduced sewage lagoon and carry out work.During work, the interior operating pressure of dissolving (1) is 2.5～5kg/cm
2, gas-water ratio is grasped between 0.02～0.06, and reflux ratio is 0.1～0.3.
The utility model is simple in structure, and operating process is simple, and specific power consumption is low, and unit surface water production rate height is stable; Its molten gas is effective, and bubbles volume is many, and diameter is small and even, and stability is strong, thereby reaches good decontamination effect improving, is suitable for the processing of trade effluents such as papermaking, textile printing and dyeing, process hides, meat processing, tinned pre-, sanitary sewage.
Fig. 1 is the utility model structural representation.
Claims (3)
1, a kind of free liquid level air-dissolving apparatus, include dissolving (1), reflux pump (2) and air compressor (3), dissolving (1) fuses with reflux pump (2), air compressor machine (3) by hydraulic pipe (4), pneumatic tube (5), dissolving (1) bottom is provided with rising pipe (103), the inlet mouth (101) that it is characterized in that dissolving (1) is connected with gas distribution pipe (102), has aperture (102a) on it.
