Floating multi-layer deep water oxygen increasing machine

Abstract

The invention provides a float type multilayer deepwater oxygen increasing machine, belongs to the water, wastewater, sewage or sludge treatment field. The machine comprises a magnetic shield, a compressing blower, a middle layer aerator, a water-gas mixture circulator and a submersible motor. The air inlet of the blower is connected with a vent pipe. The middle layer aerator is connected with the vent pipe. The water-gas mixture circulator comprises a holding frame, a bowl shaped air outlet and a circulator. The holding frame is a hollow pipe. The lower outlet of the holding frame is connected with the circulator. The bowl shaped air outlet on the lower end of the vent pipe is fixed with the holding frame. The submersible motor is provided with an upper end output shaft and a lower end output shaft. The machine has a simple structure, and solves the problems of great deepwater oxygen increasing pressure, hard transferring of the air and the dissolution. The transfer rate and the utilization rate of the oxygen are high, the failure rate is low, the maintenance is simple and convenient and the deepwater aeration effect is good.

Description

technical field [0001] The invention relates to a floating multi-layer deep-water aerator, which belongs to the field of water, waste water, sewage or sludge treatment, in particular to an aerator for sending air into a deep-water area. Background technique [0002] Various aerators currently in use, the aeration methods used include: blast aeration, jet aeration and mechanical aeration, etc. The main equipment is centrifugal blower, Roots blower, high-power motor and various A kind of surface aeration device, the power is mostly 200 kW to 700 kW, and the weight is more than 2 tons. During use, the aeration holes are generally blocked, the depth of oxygen flushing is not enough, the amount of oxygen flushing is too small, the air distribution is uneven, and it is inconvenient to maintain. , high energy consumption, high cost and other issues. The way to achieve oxygenation is relatively simple, mainly using surface aeration device, the aeration volume is small, the gas cann...

[0002] Various aerators currently in use, the aeration methods used include: blast aeration, jet aeration and mechanical aeration, etc. The main equipment is centrifugal blower, Roots blower, high-power motor and various A kind of surface aeration device, the power is mostly 200 kw to 700 kw, and the weight is more than 2 tons. During use, the aeration holes are generally blocked, the depth of oxygen flushing is not enough, the amount of oxygen flushing is too small, the air distribution is uneven, and it is inconvenient to maintain. , high energy consumption, high cost and other issues

The way to achieve oxygenation is relatively simple, mainly using surface aeration device, the aeration volume is small, the gas cannot enter the deep water area for aeration, which has a great impact on the effect of oxygenation, the vibration of the machine is large when rotating, and the parts are worn Serious, heavy maintenance, high power loss, low transfer rate and utilization of oxygen
