A kind of energy-saving sludge lift technique
The utility model relates to a kind of energy-saving sludge lifting and establishes pendulum, is applicable to sludge settling delivery system in the water treatment procedures such as feedwater, draining.
In useless, sewage disposal, it is requisite technique step order in sludge reflux and discharge process that mud is carried, and what sludge lifting generally adopted at present is the mechanical means such as water pump, spiral, although carry reliable, but working cost is high, and obstruction and maintenance workload large.
Summary of the invention
The utility model object is: a kind of energy-saving sludge lift technique is efficiently provided, and simple in structure, easy to use, working cost is low, and anti-clogging plug, maintenance are conveniently.Only need provide a road source of the gas just can realize bringing normally into operation, save energy, reduces investment outlay, and can effectively solve the problem that Sludge in Sewage Treatment promotes.
The technical solution of the utility model is: a kind of energy-saving sludge lift technique, comprises water suction hydraucone, suction pipe, inlet pipe, rotation spray valve, air lift tank body, gate valve, hand hole, shore pipe; Described water suction hydraucone pipeline is connected to suction pipe; The outlet of described inlet pipe extends suction pipe bottom, and inlet pipe exit arranges rotation spray valve, and described rotation spray valve is positioned at suction pipe, under gaseity, and rotary jet; Described suction pipe top arranges air lift tank body; Described air lift tank body upper end is provided with gate valve and checks hand hole, and end connects shore pipe.
Further, described suction pipe top is provided with a spherical air lift tank body that can carry out gas-liquid separation and double as the distribution tank that promotes mud.
Further, described rotation spray valve and inlet pipe outlet adopt screwed connection, are convenient to equipment replacement.
Further, in described inlet pipe, be designed with manual modulation valve, can control flexibly sludge lifting amount.
The beneficial effects of the utility model:
1, the utility model is simple in structure, easy to use, only need provide a road source of the gas just can realize bringing normally into operation, can effectively solve the problem that Sludge in Sewage Treatment promotes.
2, safe, practical, aspect maintenance, is easy to make, cheap;
3, effectively improve sludge lifting efficiency, reduce the energy consumption in operational process.
4, can realize anti-clogging plug effect.
5, inlet pipe exit arranges rotation spray valve, can fully reduce the liquid-tight degree of the mixing wastewater with air in suction pipe in sludge lifting process, and sludge lifting efficiency heightens 10%.
Accompanying drawing content
Fig. 1 is element structure schematic diagram of the present utility model;
Fig. 2 is the partial enlarged drawing of diffuser of the present utility model;
In figure: water suction hydraucone 1, suction pipe 2, inlet pipe 3, rotation spray valve 4, air lift tank body 5, gate valve 6, hand hole 7, shore pipe 8, manual modulation valve 9.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, the utility model comprises water suction hydraucone 1, suction pipe 2, inlet pipe 3, rotation spray valve 4, air lift tank body 5, gate valve 6, hand hole 7, shore pipe 8, manual modulation valve 9, provides source of the gas by gas blower.
Described water suction hydraucone 1 pipeline is connected to suction pipe 2; 3 outlets of described inlet pipe extend suction pipe 2 bottoms, and inlet pipe 3 exits arrange rotation spray valve 4, and described rotation spray valve 4 is positioned at suction pipe 2, under gaseity, and rotary jet; Described suction pipe 2 tops arrange air lift tank body 5; Described air lift tank body 5 upper ends are provided with gate valve 6 and check hand hole 7, and end connects shore pipe 8.
Described suction pipe 2 tops are provided with a spherical air lift tank body 5 that can carry out gas-liquid separation and double as the distribution tank that promotes mud.
Described rotation spray valve 4 adopts screwed connection with inlet pipe 3 outlets., be convenient to equipment replacement.
In described inlet pipe 3, be designed with manual modulation valve 9.Can control flexibly sludge lifting amount.
The corner of described inlet mouth 3 adopts mechanical bend.
Open after blower fan, gas enters rotation spray valve through manual modulation valve and inlet pipe, gas is divided into the tiny air-flow of multiply by nozzle, sprayed by nozzle, the recoil that gas ejection simultaneously produces drives nozzle fast rotational, thereby gas is fully promptly diffused in suction pipe road bottom liquid, due to the decline of moment air pressure, the small bubbles that are diffused into liquid expand rapidly, become air pocket, bubble is due to liquid buoyancy effect spiral, and be full of whole suction pipe, it in pipe, is the mixed solution of aqueous vapor, pipe is outer is sewage, in pipe, outer bottom is connected, because the density of aqueous vapor solution is less than the outer sewage density of pipe, according to the condition of fluid balance, aqueous vapor solution just rises in suction pipe, arrive higher than after suction pipe, muddy water is raised and enters in air lift tank, flowed out by shore pipe.
In the utility model, rotation spray valve plays the effect of cutting apart air-flow, whole strand air-flow is divided into the tiny air-flow of multiply and is conducive to gas and fully mixes with liquid, form more bubbles, the in the situation that of equivalent tolerance, at utmost reduce the density of aqueous vapor solution, thereby produce larger lifting force.The high pressure draft of rotary-jet can effectively carry out abundant agitation and dilution to the follow-up high concentration sludge that enters suction pipe road simultaneously, thereby avoids line clogging.
