Description
Technical field
What the present invention relates to is a kind of pulsed air lift mud discharging device, particularly for the air lift mud discharging device of water treatment depositing reservoir, biochemical reaction tank and sludge-tank, and refluxes for sludge reflux and biochemical anti-nitre.
Background technology
The importance to environmental improvement along with industrialized development and people, for meeting water technology development and process optimization, very important to water treatment facilities advance and stability,
The main sludge discharge way of water treatment depositing reservoir, biochemical reaction tank and sludge-tank is gravity spoil disposal and submersible sewage pump spoil disposal at present.
During employing gravity spoil disposal, sludge discharge effects is subject to artificial affecting larger, owing to being subject to artificial affecting to cause not arranging or few row, to causing spoil disposal difficulty, easily obstruction, sludge anaerobic floating to affect water quality, is subject to process limitation for a long time simultaneously; Mud received unit buried depth lower than depositing reservoir, biochemistry pool and sludge-tank at the bottom of in situation, also need to carry out second lift, cause increase of investment.
Adopt electrically operated valve to replace Artificial Control, though can realize automation, valve internal is in muddy water soaking state, seepage, gets rusty and often breaks down, and finally affects sludge discharge effects, is subject to process limitation the same.
Adopt submersible sewage pump spoil disposal, its long-term operation still has larger problem, as pump long period of soaking mud state, cause seepage, get rusty and mud in fiber stop up and the damage of seal, in addition, submersible sewage pump is poor to different sludge quality adaptability, maintenance is difficulty comparatively also.
Air lift spoil disposal is compared with gravity spoil disposal and submersible sewage pump spoil disposal, have simple in structure, without the advantage such as drive disk assembly, Awaiting Parts be few, easy to maintenance.The problems such as but conventional air lift spoil disposal still exists easy obstruction, lifting capacity is little, hoisting depth is restricted, energy consumption is relatively high.
In sum, be badly in need of a kind of sludge quality accommodation of exploitation wide, easily realize automatic control, meet various process conditions settings, the spoil disposal of layouting arbitrarily, and the non-maintaining energy-conservation novel mud discharging device again of exemption from inspection.
Summary of the invention
Technical problem to be solved by this invention is to overcome the shortcoming of above-mentioned existing mud discharging device, and a kind of simple in structure, the maneuverable pulsed air lift mud discharging device of reason is excused from a college course in low energy consumption.
For solving the problems of the technologies described above, pulsed air lift mud discharging device comprises: mud inlet tube, pulse air lift tank, pulse unit, discharge pipeline, sludge outlet pipe, air inlet pipe, fixed support.Described mud inlet tube is welded on the bottom of pulse air lift tank, in pulse air lift tank, establish pulse unit and discharge pipeline, one end of pulse unit is connected with mud inlet tube, and the other end connects one end of discharge pipeline, sludge outlet pipe is welded on pulse air lift tank top, air inlet pipe is welded on the top in pulse air lift tank outside, and fixed support is welded on pulse air lift pot bottom outside.Utilize the gas of air feed source of the gas to enter pulse air lift tank by motor-operated control valve and air inlet pipe, gas high velocity jet after pulse unit enters discharge pipeline, mix with the mud mixture in discharge pipeline, along with gas constantly enters discharge pipeline, the difference that is stressed effect, gas drives mud mixture to discharge by sludge outlet pipe.
Motor-operated control valve adjusting air inflow quantity is set in described air inlet pipe, reaches automatic control spoil disposal flow and the object of spoil disposal time.
The quantity of described pulse unit is more than or equal to 2, and described pulse unit even circumferential is distributed between mud inlet tube and discharge pipeline.
Described pulse unit is strip hole, and its outer wall aperture is greater than inwall aperture and is trapezoidal shape.The large aperture of outer wall makes pulse unit can absorb a large amount of gas, and air velocity can be improved in small-bore.
Described fixed support is telescopic/fixed support, is applicable to the mud height of the multiple degree of depth, has applicability widely.
Pulsed air lift mud discharging device tool multipurpose function of the present invention, the gravity spoil disposal spoil disposal of alternative various process conditions and submersible sewage pump spoil disposal, also can be used as proposing the anti-nitre of mud and biochemical anti-nitre backflow, adapt to sludge quality wide ranges, can improve spoil disposal operating environment, energy-conserving and environment-protective, realize automation spoil disposal, easy to operate, non-maintaining freedom from repairs, and can safeguards system long-period stable operation.In view of the needs of China's modernization construction energy-saving and emission-reduction, this invention has wide market prospects, and its release must bring good economic benefit and social benefit.
