Description

Suspended gas mixer

Technical Field

The invention relates to the field of water treatment, in particular to a suspended gas mixer.

Background

In the water treatment process, COD, ammonia nitrogen and the like are main monitoring indexes of sewage, the removal of COD and ammonia nitrogen of mine water, domestic sewage and the like is a problem which needs to be solved urgently, the aeration of the traditional sewage treatment is mainly carried out by using an aeration head, the aeration range of the aeration head is small, and the blockage is easy. Meanwhile, long-term sludge precipitation affects the aeration effect. The sludge is always cleaned and dug, the manual labor is dirty and heavy, the resources are wasted, the environment is polluted, if the sludge is not cleaned in time, the sludge is deposited at the bottom, the volume of the water tank is reduced, and the normal operation of the whole water treatment system is influenced. The pure aeration does not help the treatment of the sludge, so a set of novel suspended gas mixer needs to be designed and can be used for aeration and dredging at the same time.

Disclosure of Invention

The invention provides a suspended gas mixer, which can be used for treating and aerating coal slime in water treatment, can suspend and treat the coal slime at the bottom of a pool, can remove COD (chemical oxygen demand) and ammonia nitrogen, only uses compressed air as a power source, and is energy-saving and environment-friendly.

A suspended gas mixer comprises a gas pipeline, a rotating device, a rotating body and a gas nozzle.

The rotating device is composed of a fixed end, a rotating end and a bearing, wherein the outer end of the bearing is tightly matched with the fixed end, and the inner end of the bearing is tightly matched with the rotating end. Mechanical seal device installs outside stiff end and rotatory end junction, prevents that gas from leaking, and bearing externally mounted has the bearing oil blanket, prevents that the bearing from intaking into the ash. The rotating end is fixed on the fixed end through a clamp spring.

The gas pipeline is a carbon steel pipeline, the lower end of the gas pipeline is connected with a rotating device, and the rotating end is connected with a rotating body. More than one group of gas nozzles are arranged on the rotating body, each group of gas nozzles is provided with two nozzles which are correspondingly arranged in the middle of the rotating body at equal intervals.

Preferably, the method comprises the following steps: the gas shower nozzle is two sets of, and is L type gas shower nozzle, and L type gas shower nozzle one end is installed on the rotator perpendicularly, and the shower nozzle 90 degrees installation corresponds end shower nozzle 135 degrees installation, and gas passes through the bearing and gets into the inside gas cavity of rotator, through gas shower nozzle high pressure blowout, promotes the rotation end and rotates. This design can make submarine silt come-up, increases stirring efficiency.

Preferably, the method comprises the following steps: the rotator is the cavity body of circular or elliptical type, because of the symmetry volume, no longer shear water during rotatory, the resistance reduces, and the revolution of rotator will promote under the same condition of power to increase and stir the area and reach the high-efficient degree of depth desilting.

The utility model discloses an effective effect is: set up a plurality of suspended gas and mix the ware bottom the pond, make the suspended gas to mix the ware high-speed rotatory increase under the gas piping effect and stir the area, the silt of high rotation messenger bottom of the pool no longer deposits, in time gets rid of after the misce bene. Under the action of gas-mixing stirring of the suspended gas mixer, coal particles are used as biological filler to realize the purpose of removing pollutants in water, and meanwhile, the functions of removing COD and ammonia nitrogen can be realized by utilizing the existence of aerobic and anoxic areas in the reactor.
