Abstract
The utility model relates to a jet flow type combined gas and water distributor, belonging to the water processing field, and comprising a flow jet device, a flash tank, an air distributor and a multi-end water distributor. A connection flash tank is provided between a diffusion tube and a multi-end water distributor; one end of the flash tank is connected with the diffusion tube, and the other end of the flash tank is connected with the multi-end water distributor; the cross-section area of the flash tank is bigger than that of the multi-end water distributor; the flash tank is provided with an air outlet which is provided with one adjustable valve. The jet flow type combined gas and water distributor has simple structure, satisfies the technology needs of the sewage treatment, reasonably adjusts the air-water allocation proportion, reduces the cost, and can be suitable for each link of the technology of the sewage treatment.
Description
Affiliated field the utility model jetting type combination air water distribution device belongs to water treatment field, particularly relates to the ejector that a kind of aeration of stretches is used.
Technical background is the sewage disposal in field of environment protection at present; the required dissolved oxygen of its technology adopts aeration or compressed air source to provide; traditional jet-flow aeration is that single air water mixes; by ejector air is sucked; form admixture with water; its effect can only be used in limited range; thereby make the utilization ratio of dissolved oxygen low; maldistribution does not reach the integrated of integrated artistic, can only make a ring of sewage treatment process; and compressed air source provides dissolved oxygen to have high input; the expense height, setting accuracy requires high, the whole cost height of technology.
Utility model content the purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of simple and practical, the utilization ratio height of dissolved oxygen, distributed uniform, the phase-splitting of air water mixed solution, reduce cost, optimize the jetting type combination air water distribution device of technology.
The purpose of this utility model reaches by following measure, it is by ejector, flash vessel, air distributor, the multiterminal water distributor is formed, ejector is by water-in, nozzle, air suction inlet, diffuser tube is formed, between diffuser tube and multiterminal water distributor, be provided with and be connected flash vessel, one end of flash vessel connects diffuser tube, the other end of flash vessel connects the multiterminal water distributor, the area of the cross section of flash vessel is greater than the area of the cross section of diffuser tube, the area of the cross section of flash vessel is greater than the area of the cross section of multiterminal water distributor, be provided with air at flash vessel, be provided with a regulated valve at the air place, power-driven pump is delivered to nozzle with water by water-in, form high velocity flow, air sucks through air suction inlet, form the air water mixed solution, be tending towards separating after mixing in diffuser tube, the air water mixed solution enters flash vessel, because the area of the cross section of flash vessel is greater than the area of the cross section of diffuser tube, the area of the cross section of flash vessel is greater than the area of the cross section of multiterminal water distributor, form flow velocity and reduce in flash vessel, the air water mixed solution forms good separation condition in flash vessel, and gas phase is separated from mixed solution, regulated valve by air is discharged, and is transported to the multiterminal water distributor under pressure through the liquid flow of separating gas phase.
The utility model connects air distributor at the air place that flash vessel is provided with, air distributor can play the dilatation of mixed solution on the one hand, air and liquid are thoroughly separated, simultaneously the air of separating is passed through distribution openings, distribute to needed feed point.One end of air distributor is connected the air place of flash vessel, and air distributor is provided with more than one air distribution openings.
The utility model is simple in structure, can make full use of the use value of equipment, satisfies the sewage treatment process needs, rationally adjusts the air water allocation proportion, reduces cost, and goes for each link of sewage treatment process.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
Accompanying drawing 3 is left views of accompanying drawing 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
