Description
Technical field
The invention belongs to water-treatment technology field, more particularly to a kind of low energy consumption depositing reservoir pulse for sewage disposal is sent out
Generating apparatus, it is the improvement for the Chinese invention patent 201710509880.9 submitted to same applicant.
Background technology
Depositing reservoir is to complete water and the coagulating treatment technique of waste water mixing, flocculation reaction and the solid-liquid including water and medicament point
From three processes of grade in the Special Equipment of one.In depositing reservoir, the medium for playing retention separation impurity particle effect is in outstanding
The body refuse of floating shape, and plusator is a kind of using appropriate hydraulics are created, and induces suspension slime layer in pond to produce week
The expansion and contraction of phase property, in raw water tiny flocculation particle pass through carry out contact flocculation with the body refuse in superposed layer remove suspend it is miscellaneous
The processing unit of matter.There is no stirring system in plusator, due to the periodic expansion of slime layer, contractile motion, raw water is led to
Filtration can be produced to the flco in water, and reach good treatment effect when crossing the slime layer of swelling state.In addition, pulse
Depositing reservoir is by the way of bottom water distribution water inlet tube, and it can make the concentration of superposed layer tend to be uniform, it is therefore prevented that mud granule exists
Bottom of pond deposits.
Plusator can be divided into according to the difference of waterpower pulse occurring mode by vacuum type plusator, bell jar siphon
Formula plusator etc..Although plusator has such as：Clarifying efficiency is high, pond is deeply shallower, easy for construction, low cost, with
And without underwater installation, repair the advantages that more convenient, but vacuum type plusator needs to set up a set of vacuum equipment, operation
Maintenance difficulties are larger；The loss of flood peak is larger in hydrocone type plusator running, pulse period more difficult control, operational administrative
It is it is required that higher.Cause treatment effect bad, its large-area applications of limit value.
Therefore, applicant has applied for a kind of depositing reservoir pulse generating method of patent and device (application number
201710509880.9), in the centrally disposed cylinder body of depositing reservoir, formed periodically using flywheel turns driving reciprocating motion of the pistons
Take out press through journey produce waterpower pulse；Induce suspension slime layer in pond to produce periodically expansion and shrink, promote solid in raw water
Body impurity carries out contact flocculation, absorption with established body refuse；The suspension body refuse of formation continues to rise and in clear water zone with current
Interior completion separation of solid and liquid, processing water is by collector pipe outflow depositing reservoir；Suspension slime layer is maintained by the regular discharge of discharge pipeline
In reasonable altitudes.
In Mechanical Driven plusator running, the resistance that piston needs to overcome is：
F=ΔH×ρ×A×g+f
In formula：Δ H --- the liquid level difference in depositing reservoir reactor body and piston/cylinder
The cross-sectional area of A --- piston/cylinder
The unit weight of ρ --- water
G --- acceleration of gravity
The frictional force of f --- piston and cylinder body
When the piston is moving down, pressure caused by the liquid level difference in depositing reservoir reactor body and piston/cylinder should be overcome
Δ H × ρ × A × g, while need to overcome the frictional force f of piston and cylinder body；When the piston is moving up, depositing reservoir reactor master
Pressure caused by body high level (size is Δ H × ρ × A × g) can promote piston upwards, additionally need to overcome f.
It follows that stress differs greatly during piston raising and lowering.Driven according to homogeneous flywheel
The moment of torsion of piston then flywheel must is fulfilled for the demand in least favorable situation (piston operation downwards to minimum point), and rises in piston
During then do not need flywheel to provide excessive moment of torsion.Therefore, energy will be caused significantly using homogeneous flywheel in the device
Degree, insignificant waste.
