Polycyclonic vacuum collectors for virtually non-stop environmental remediation

A vacuum collector is provided comprising a suction hose, a first drum with a cover having a cylindrical head capable of generating powerful, small-diameter cyclones, a second drum capable of generating large-diameter cyclones, and a stack of three modules containing vacuum-producing motors atop a HEPA filter atop primary filters. The suction hose is connected to the inlet of the small-diameter cyclone-generating head on the cover of the first drum. The stack of modules containing motors, HEPA filter, and primary filters is mounted on the second drum. The two cyclonic drums communicate through a flexible vacuum hose. When the vacuum-producing motors pull air from the interior of the vacuum collector, the suction hose sucks atmospheric air mixed with contaminants from a surface into the head, which spins the contaminant-laden air-stream into a powerful, small-diameter cyclone. As a result of cyclonic action, the contaminant laden air-stream spirals to the bottom of the first drum, deposits most of its contaminants, reverses course, exits the drum, and enters the second drum, where it spins into a large-diameter cyclone, deposits more contaminants, passes through the primary and HEPA filters, and exhausts via the vacuum-producing motors. Collectors comprising more than two communicating cyclonic drums for tailored environmental remediation are also described.

River ecological flow maintenance-orientated reservoir optimizing and dispatching method

The invention discloses a river ecological flow maintenance-orientated reservoir optimizing and dispatching method, which comprises the following steps of: diving influx flow of a reservoir into four intervals according to the magnitude of the flow, diving the storage capacity of the reservoir into four intervals by using an upper dispatching curve, a lower dispatching curve and a dead storage curve, and formulating different water supply and letdown rules when the influx is in different flow intervals and the water level is positioned in different storage capacity intervals. When the flow is positioned in the interval containing flat shoal flow, the influx flow is totally used for meeting river ecological flow after meeting the water supply requirement; when the influx is positioned in the minimum flow interval, the reservoir reduces letdown to maintain river low-water ecological pulse; and when the water level is positioned in the interval above the upper dispatching curve, the reservoir enlarges the letdown to ensure the flood control function. The method also comprises the following steps of: quantizing a target value of dispatching by adopting a variable range method to meet the constrained planned water supply reliability, and simultaneously optimizing parameters in the dispatching rule by using a genetic algorithm to acquire optimal dispatching parameters under the condition of meeting the planned reliability.
