Technical field
The present invention relates to setting pot sediment outflow technical field in sewage disposal, more particularly to a kind of rotational flow grit chamber draining sand method
And sand-removing system.
Background technology
Sewage is inevitably mixed into silt particle during migrating, flowing and collecting.If the sand in sewage does not sink in advance
Drop, which separates, to be removed, then can influence the operation of subsequent processing device.Most importantly wear pump, block pipe network, interference is even broken
Bad biochemical processing process process.Setting pot is mainly used in removing particle diameter in sewage and is more than 0.2mm, and density is more than 2.65t/ cubic meters
Sand grains, with facilities such as protective conduit, valves from wearing and blocking.
At present, the setting pot of municipal sewage plant substantially uses two types：One kind is exposed using relatively more extensive
Gas setting pot, by pond side air hose control aeration, make sewage formed with certain speed advance eddy flow (perpendicular to
Water (flow) direction), this pond type has stable desanding effect；Another kind is rotational flow grit chamber (its using waterpower vortex desanding
Eddy flow and water (flow) direction are basically identical), have the advantages that pond type is simple, take up an area province, operating cost is low, desanding effect is good, got over
To be more valued by people.This patent is studied mainly for rotational flow grit chamber.The sediment outflow of rotational flow grit chamber uses at present
Two kinds of forms, one kind is to lean on sand pump sediment outflow, it is advantageous that equipment is few, easy to operate, but the wear problem of sand pump is also increasingly
Paid close attention to by user；Another kind is air lift sediment outflow, it is advantageous that system is reliable, durable, but equipment is relatively more.
But the sand amount of setting pot is not monitored and discharged in current sewage disposal process, usual operating personnel according to
Carry out a sediment outflow operation at regular intervals according to passing experience.Because change be present in different time sections sewage quantity, concentration of wastewater,
If sand setting amount and timely sediment outflow can not accurately be known, it is easy to cause obstruction even sandstone to overflow and influence the normal of sewage
Processing.
The content of the invention
The present invention is made to solve above-mentioned technical problem present in prior art, and its object is to provide one kind
The rotational flow grit chamber draining sand method and sand-removing system that energy is convenient and swift, reliability is high.
According to an aspect of the present invention, there is provided a kind of rotational flow grit chamber sand-removing system, for the sediment outflow of rotational flow grit chamber,

Member, wherein：The early warning line is arranged in the side wall of the sand hopper of the rotational flow grit chamber, and different early warning lines are apart from the sand hopper bottom
The height in portion is different；The sensor is arranged in the side wall of the sand hopper, for measure in the sand hopper sandstone with it is described pre-
The distance of alert line；The data that the data acquisition unit gathers the sensor measurement are transferred to by the signal transmission unit
Control unit, described control unit setting sediment outflow condition, the sediment outflow condition be the sand hopper sandstone and the early warning line away from
Reach setting quantity from the quantity less than secure threshold, when the sediment outflow condition is achieved, described control unit is sent instructions to
The control execution unit, carry out sediment outflow.
According to another aspect of the present invention, there is provided a kind of rotational flow grit chamber draining sand method, the row for rotational flow grit chamber
Sand, including：At least one early warning line is set in the side wall of the sand hopper of the rotational flow grit chamber, and different early warning lines are apart from the sand
The height of bucket bottom is different；Multiple sensors are set in the side wall of the sand hopper of the rotational flow grit chamber, for measuring the sand
The distance of sandstone and the early warning line in bucket；The distance sensed according to sensor, judges whether to reach sediment outflow condition, the sediment outflow
The quantity that the distance of sand hopper sandstone described in condition and the early warning line is less than secure threshold reaches setting quantity；If reach described
Sediment outflow condition, carry out sediment outflow.
Above-mentioned rotational flow grit chamber sand-removing system and method will be turned by the operation for manually by virtue of experience carrying out regular sediment outflow originally
It is changed into monitoring sand amount in real time by rotational flow grit chamber sand-removing system, by the sediment outflow conditions correlation with setting and then autonomous sediment outflow,
The blank of the autonomous sediment outflow of current rotational flow grit chamber is filled up, improves the promptness and initiative of system, reduces sandstone accumulation
Risk.
Further, since operating personnel only need Focus Control module, without observation and sediment outflow, staff has been liberated, has been improved
Productivity and operating efficiency, in the long term reduce the cost of sewage disposal.
Furthermore above-mentioned rotational flow grit chamber sand-removing system and method are not exclusively for some sewage plant, and in production
It can continue to optimize perfect, work well, possess dissemination.
