Description
The present invention relates to a kind of two siphon constant volume sewage effluents that are used for water quality flow proportional sampling method and this method of enforcement of environmental monitoring work, press the proportional method of sampling of flow (being called for short two rainbow constant volume draining proportional sampling methods) and system equipment.
Optimal water quality sampling technology is can be by flow change continuous sampling automatically pro rata.In existing water quality sampling technology, more satisfactory with circulation proportional sampling method, (patent No.: 89100831.4 publication numbers: CN1037783A) it is three layers of concentric garden structure that the garden pipe is formed to have obtained patent of invention, utilize the flow by gravity of water, cause even annular flow field in discharge process, the current of getting the fan-shaped section of its sub-fraction from annular flow section are representational mixed sample.The influence that it is not changed by flow velocity, sampling is than accuracy height, and related coefficient is good, has guaranteed the accuracy of sampling quantity from principle.But its weak point has 2 points, the bad adaptability of first water yield size, particularly then can not form even annular flow field can not satisfy the caliber flowing full time in that the water yield is little, lost the intention of proportional sampling fully, when the water yield was very big, equipment size was also big, the circulation bore is very wide, realize that uniform flow field is also difficult, influence sampling proportional precision, the circulation proportional sampling only adapts to the medium and small water yield.Be that sampling quantity and sampling are too bigger than all two,, it is that thief hatch is the long-pending ratio with the garden annular cross-sectional area of sector crosssection, suppose that ratio gets 2/1000ths, then the segment angle of thief hatch area has not been 1 degree, has belonged to very carefully narrow, be difficult to control its precision, and adopt in actual applications the water sample amount also too big, also must remake the secondary sampling processing, the sampling quantity of actual needs is very big, the usefulness that can satisfy assay is just enough, but water sample must have sufficient representativeness.
Purpose of the present invention, be to provide a kind of strong to discharge of sewage size adaptability, the special proportional sampling that adapts to big flow, sampling quantity and sampling are very littler than all, and have water quality and fill a representational pair of siphon constant volume draining proportional sampling method and system equipment of part.
Main points of the present invention are, the siphon pond of two different water levels of design height, (referring to accompanying drawing one) (claim not only regulate siphon pond) is equipped with inverted U-shaped U trap but also claims high-order siphon (7) and water level controller (3) in high-order siphon pond (4), the top of high-order tube (7), design has two solenoid valves, one is exhaust solenoid valve (5), be received in the electric signal of the water level controller (3) in this siphon pond and open electromagnetic valve, siphon starts, another is an air inlet solenoid valve (6), acceptance is located at the electric signal of the water level controller (10) in the low level siphon pond (9) and opens electromagnetic valve, and air enters siphon (7) and disconnected rainbow.The exit design of siphon (7) has water tight compartment (8).The effect of this siphon pond (4) and siphon (7) is to make siphon (7) often to do the flowing full discharging and adapt with the size that changes flow velocity and the variation of flow of inlet water size.Supply water to low level siphon pond (9), when the rainbow draining was opened in low level siphon (11), the disconnected rapidly rainbow of high-order siphon (7) stopped to supply water, and had guaranteed that low level siphon (11) presses the constant volume draining at every turn, and low level siphon pond (9) claims constant volume siphon pond again.Water level controller (10) is installed in the pond, and bell shape siphon (11) claims low level siphon and special-purpose tubular type proportional sampling device (13) again.The top of low level siphon (11) is provided with solenoid valve (12), accepts the electric signal of water level controller (10) and opens electromagnetic valve and start siphon, and intermittently big flow draining is done in siphon (11).Each water discharge V ' of siphon (11) should satisfy following condition:
