Horizontal oscillation jet-flow mixing integrated device

Abstract

The present invention relates to a kind of aerating apparatus for making organic waste water and lake water undergo the process of aerobic biological treatment, in particular, it is a horizontal oscillation jet flow mixing integrated equipment. It includes the following several portions: suction chamber, air drain communicated with said suction chamber, high-pressure pump and mixing pipe, in which the mixing pipe is horizontally mounted, and the outlet end of said mixing pipe is equipped with an oscillation device.

Description

technical field [0001] The invention relates to an aeration device suitable for aerobic biological treatment of organic waste water, various liquid media used in biological processes, lake water, etc., especially a horizontal oscillating jet used for dispersing and dissolving gas in liquid Hybrid integrated device. Background technique [0002] At present, when carrying out aerobic biological treatment of sewage, the structure of commonly used equipment includes an air compressor and several microporous aeration heads communicated with it through a mixing tube. When in use, several microporous aeration heads need to be installed on the bottom of the aeration tank, and the top surface of the aeration head is required to be at the same elevation, that is, the top elevation of the aeration head is controlled very strictly, otherwise the air output will be uneven, which will seriously affect the efficiency; In addition, because the air compressor will generate very loud noises,...

Problems solved by technology

But AIRE-O 2 The inflator still has the following defects: first, the motor drives the rotating shaft to rotate at a high speed to generate strong noise, causing environmental pollution; second, during operation, the rotating shaft and the blades rotate at high speed, which is easy to wear and tear, so the service life is short

When in use, the water flow ejected from the high-pressure nozzle carries the surrounding air into the mixing tube, and is sprayed out from the outlet at the bottom of the mixing tube to carry out sewage treatment. This kind of aeration device has a long service life because it has no mechanical loss during operation. And the noise is low; but because the mixing tube is installed vertically, the liquid column injected into the mixing tube will directly hit the bottom plate at the bottom of the pool, resulting in energy loss, that is, the mechanical energy is not fully used for sewage treatment, and part of the bubbles generated will quickly It rises to the surface of the water body and loses its function, so it consumes a lot of energy and has low efficiency. At the same time, it does not have the function of pushing the flow from the back to the front, so it is not suitable for use in urban oxidation ditch.

And when using this kind of device, if the bottom plate is not installed at the bottom of the pool, the liquid column sprayed out by the mixing tube will impact the sludge at the bottom of the pool, making the water turbid, and the purification effect is not ideal
