Description
The utility model relates to a kind of pressurization bio-contact oxidation and handle waste water plant, particularly gas and liquid flowing formula pressurization contact oxidation tower belongs to technical field of waste water processing.
Handle in the waste water technology at the pressurization bio-contact oxidation, especially utilize the pressurization contact oxidation tower to handle waste water new technology (CN88211365.8), have that energy consumption is low, efficient is high, take up an area of less, advantage such as stenchless escaping.But in the bigger process of wastewater treatment capacity, the filler of oxidizing tower air water ingress damages easily, and it is bad to produce the interior gas-to-liquid contact of tower, goes out Ta Shui and contains bubble, and particularly liquid level is wayward in double tower or multitower technical process.Thereby press for and a kind ofly overcome above-mentioned insufficiently, be suitable for the bigger pressurization contact oxidation tower new device of treatment capacity.
The utility model aims to provide a kind of gas and liquid flowing formula pressurization contact oxidation tower, and particularly a kind of being suitable for formed double-column process with gas-liquid counter current formula pressurization contact oxidation tower, and is applied to the pressurization contact oxidation tower of the bigger organic waste water of treatment capacity.Thereby the first tower gas-liquid ingress filler is fragile in the time of can solving the double tower combination, and gas-to-liquid contact is bad in the tower, goes out Ta Shui and contains the interior pressure shakiness of tower in bubble and the double tower combination process, the uppity problem of liquid level.
The gas and liquid flowing formula pressurization contact oxidation tower that the utility model proposes is realized by following technical proposals.
Water, the gas of gas and liquid flowing formula pressurization contact oxidation tower all enter by the air water mixer of tower inner bottom part, and in the air water mixer, air water is discharged into the bottom of tower after mixing.Be provided with the air water redistributor at the middle part of tower, certain distance is established a baffle plate below nearly water outlet, enters water outlet to avoid bubble.
A kind of gas and liquid flowing formula pressurization contact oxidation tower of the utility model design, its air water mixer is located at the intravital bottom of tower, cylindrical structure.In tube, fill cascade ring.Water is entered by the water inlet pipe of center, tube top, and pressurized air is then entered by the inlet pipe of center at the bottom of the tube, and through the perforated pipe ejection, air water is after mixing in mixed cylinder, and the aqueous vapor squit hole through barrel discharges again.Because water, gas are through repeatedly being cut and violent turbulence during cascade ring in the mixed tube, thereby gas all is dispersed in the water with small bubbles.This has not only strengthened air water contact and mass transfer, also can reduce the impact of water flow to hanging filler in the tower, prolongs the life-span of filler.
The air water redistributor of gas and liquid flowing formula pressurization contact oxidation tower is located at the middle part of tower body.It has that the some riser pipes that extend downwards are connected with sieve tray and the structure formed by one.During the work of pressurization contact oxidation tower, water is from bottom to top crossed sieve tray by riser pipe and is arrived its top.Below the air water redistributor, less because of sieve aperture, the resistance that liquid passes sieve aperture surpasses the resistance that flows through riser pipe.So have only gas just to rise, thereby form one deck air chamber through sieve aperture.When the gas-liquid rising of air chamber below entered air chamber, the air in bubble breaking and the air chamber was mixed, passes through sieve aperture then, is divided into new bubble, and the water with the sieve aperture top contacts again.According to the gas-liquid mass transfer principle, the formation of the fragmentation of underwater bubble and new bubble will speed up mass transfer process, thereby helps accelerating biological process.
For preventing the water outlet band bubble of tower, about 100mm establishes a baffle plate in the place below rising pipe exit, top, and the bubble that rises in the anti-sealing directly enters rising pipe.On the top of tower, establish the upper and lower limit liquid level alarm, for operator's dominant discharge and liquid level.
The utility model can be combined into double tower or multitower flow process with gas-liquid counter current formula pressurization contact oxidation tower.In double-column process, the utility model is first tower, and gas-liquid counter current formula pressurization contact oxidation tower is second tower.The flow process of water is series connection, promptly in order by first tower and second tower.The flow process of gas is in parallel, and promptly gas enters first tower and second tower respectively, and the escape pipe of two column overhead links to each other.Tail gas also has overbottom pressure, can utilize once more.
