the water passing gallery and the reflux components are communicated with the water passing gallery, and the gas stripping components are communicated with the reflux components. Each group of reflux components correspondingly extend into one mud bucket, each group of reflux components is correspondingly connected with one group of air stripping components, the reflux components enable sludge in the mud bucket to reflux into the water passage, and the air stripping components provide reflux power for the reflux components.

Therefore, the gas stripping reflux device provided by the utility model is provided with a plurality of groups of gas stripping components, and one group of gas stripping components respectively and correspondingly provides reflux power for one group of reflux components, so that the condition of uneven gas distribution is greatly reduced, and the reflux effect of the reflux components is improved.

The principles and structures of the present utility model are described in detail below with reference to the drawings and the examples.

As shown in fig. 1 and 2, the present utility model provides a gas stripping reflux apparatus, which includes a water passage, a plurality of reflux assemblies in communication with the water passage, and a plurality of gas stripping assemblies in communication with the reflux assemblies. Wherein, a set of backward flow subassembly corresponds and stretches into in a mud bucket, and a set of air stripping subassembly is connected in a set of backward flow subassembly correspondence, and air stripping subassembly provides backward flow power for backward flow subassembly and makes the mud in each mud bucket flow back to the water gallery in, and the water gallery is concentrated the mud in each mud bucket and is sent into the anoxic tank in concentrated processing.

Therefore, compared with the prior art that a plurality of groups of reflux components share the same stripping component, each group of reflux components in the stripping reflux device provided by the utility model are provided with corresponding stripping components for providing reflux power for the stripping components, so that the problem that the power provided by the stripping components is unevenly distributed in the plurality of groups of reflux components is greatly reduced, and the reflux effect of the gas reflux device is improved.

Specifically, as shown in fig. 1 and 2, in the present embodiment, the water passing gallery 1 includes one straight main gallery 11 and a plurality of return flow through grooves 12 communicating with the main gallery 11. The outlet end of the reflux assembly extends upwards into the reflux groove from the bottom of the reflux groove, and the inlet end of the reflux assembly extends downwards into the mud bucket. When the air stripping component provides reflux power for the reflux component, the reflux component can send the sludge in the mud bucket into the reflux groove, and then the sludge flows into the main gallery from the reflux groove.

Further, as shown in fig. 2, in order to prevent the sludge in the non-return flow tank from being sputtered out of the return flow tank, a return cover 4 for blocking the splashing of the sludge is provided on the top of the return flow tank 12. Simultaneously, can be through accurate calculation before using this mud back flow desorption mud in order to guarantee that the highest liquid level of mud in the circulation groove can always be less than the height of the exit end of backward flow subassembly, prevent that mud from flowing backward.
