Abstract
The invention belongs to the field of sewage treatment of environmental protection. In the invention, compressed air is sent to a sludge suction pipe by utilizing an air lift principle, and the average density of an air-water mixture in the sludge suction pipe is less than the density of water in a secondary settlement pool, so a flow pressure difference between the sludge suction pipe and the secondary settlement pool is improved, thereby the sludge flow velocity is improved, and a blocking problem is solved.
Description
1, technical field
The invention belongs to the sewage treatment area of environmental protection category
2, background technology
The suction dredge that sewage treatment area is conventional, is the mud inspiration sludge sump at the bottom of adopting siphon method by second pond, and then flows into mud-collecting well.The in the situation that of containing more inorganic particulate matter in sludge concentration in higher or mud, can cause the situation that dredging tube silts up, mud-water separation is not smooth.
In order to solve dredging tube, stop up, generally adopt giant flushing, the methods such as second pond of finding time, these methods are time-consuming, and for the suction dredge of frequent obstruction, personnel labor intensity is too high, if processed not in time, will pollute accident.
3, summary of the invention
The present invention utilizes air lift principle, and compressed air is sent into dredging tube, and the averag density of the air-water mixture in dredging tube is less than the density of water in second pond, improves thus the flow differential pressure of dredging tube and second pond, thereby improves mud flow velocity, solves blockage problem.
4, accompanying drawing explanation
Figure is the flow chart that air lift technology is implemented.The air coming from air blast (8) is through house steward (7) minute two-way main (5), by main valve (6), control and open and close respectively, enter again arm (4), each arm is controlled and is opened and closed and aperture by arm valve (3), arm inserts respectively dredging tube (10), (1) be second pond pond body, (2), (9) are respectively second pond water level and scraping and sucking machine (suction dredge) mud groove mud position.
5, the specific embodiment
Embodiment one:
For installing type suction dredge (or scraping and sucking machine) under water, Ke Cong introduces pneumatic manifold outside pond, house steward is upper arranges rotatable seal nipple at scraping and sucking machine center, this joint can guarantee that in the situation that equipment rotates joint is air tight, at each mud suction mouth place, compressed air arm is set respectively, on main or arm, can establishes valve and control keying and flow.
Embodiment two:
Crane span structure for suction dredge (or scraping and sucking machine) is sitting in the situation more than water surface, Roots blower is arranged on mud and water separating equipment (suction dredge or scraping and sucking machine), the center power connecting column that power supply is taken from, shares a power supply with the motor that drives mud and water separating equipment to rotate.
Go out on the house steward of air blast valve can be set, each dredging tube all arranges an air lift arm, valve can be set on arm and control and open and close and flow.
Embodiment three:
Crane span structure for suction dredge (or scraping and sucking machine) is sitting in the situation more than water surface, Roots blower is arranged on mud and water separating equipment (suction dredge or scraping and sucking machine), the center power connecting column that power supply is taken from, shares a power supply with the motor that drives mud and water separating equipment to rotate.
The outlet header of air blast divides two-way main, and two-way main arranges respectively valve and controls keying.Each main carries respectively compressed air to take the side that crane span structure center is starting point.Each dredging tube all arranges an air lift arm, valve can be set on pipeline and control keying and flow.
During operation, can adjust flexibly air mass flow:
(1), two main valve wide opens, now all air lift arms all can be worked.
(2), open a side main valve, close opposite side, can improve like this air mass flow of opening a side, strengthening air lift effect.
Embodiment four:
Crane span structure for suction dredge (or scraping and sucking machine) is sitting in the situation more than water surface, Roots blower is arranged on mud and water separating equipment (suction dredge or scraping and sucking machine), the center power connecting column that power supply is taken from, shares a power supply with the motor that drives mud and water separating equipment to rotate.
The outlet header of air blast by compressed air delivery to take the side that crane span structure center is starting point.Each dredging tube all arranges an air lift arm, valve can be set on pipeline and control keying and flow.
During operation, can adjust flexibly air mass flow:
(1), two main valve wide opens, now all air lift arms all can be worked.
(2), open a side main valve, close opposite side, can improve like this air mass flow of opening a side, strengthening air lift effect.
