The invention relates to a double-coil drive air-lock bi-stable electromagnetic auxiliary valve which consists of a valve body, an inlet valve seat, a valve core, a spring, an outlet valve seat, a coil A, a coil B, a socket, a gasket, a rubber O-shaped ring and a ventilation nozzle 10. By adopting the double-coil drive air-lock bi-stable electromagnetic auxiliary valve structure, the electromagnetic auxiliary valve can be independently opened and closed by independently and respectively powering the coil A and the coil B, so that the opening and closing response speed of the electromagnetic auxiliary valve can be increased. By adopting the bi-stable design, after the electromagnetic auxiliary valve is electrified for a short time to take relevant action, the electromagnetic auxiliary valve can be powered off and maintained at a stable state after the action, the electromagnetic auxiliary valve can be maintained opening without being continuously electrified, the power consumption can be effectively reduced, the energy-saving advantage is obvious when the electromagnetic auxiliary valve works stably for a long time and multiple electromagnetic auxiliary valves work simultaneously, and the low-energy-consumption design purpose can be easily realized.

One-bath two-step dyeing method for nylon/cationic dyeable polyester fabric
PendingCN109295762AReduce dyeing processReduce energy consumptionDyeing processPolyesterRoom temperature
The invention discloses a one-bath two-step dyeing method for a nylon / cationic dyeable polyester fabric. The method comprises the following steps: 1, immersing the nylon / cationic dyeable polyester fabric in a pretreatment liquid, pretreating the fabric at room temperature for 10-60 min, and then pickling the pretreated fabric; 2, immersing the treated fabric obtained in step 1 in a dye solution containing a cationic dye and an acidic dye and having a pH value of 3-7, dyeing a nylon fiber at 80-100 DEG C for 30-60 min, raising the temperature to 100-130 DEG C, and dying a cationic dyeable polyester fiber for 30-60 min; and 3, washing the dyed fabric obtained in step 2 with water at room temperature, discharging the obtained solution, and carrying out acidic color fixation at 50-70 DEG C for10-30 min. The method has the advantages of short process flow, low energy consumption, good dyeing effect and high color fastness (reaching level 4 or above).

Hydraulic power oxygenation constructed wetland
InactiveCN101885565BObvious advantage of energy savingZero energy consumptionClimate change adaptationMultistage water/sewage treatmentConstructed wetlandSludge
The invention relates to a hydraulic power oxygenation constructed wetland, belonging to the technical field of constructed wetland, waterbody ecosystem restoration and sewage treatment. A plurality of monolater modules of the hydraulic power oxygenation constructed wetland are in a stepped shape to construct the hydraulic power oxygenation constructed wetland; and each level constructed wetland is composed of a water intake device, a wetland main body and a water discharging device. The wetlands in the adjacent two layers are linked with a water intake and discharging connection device so asto ensure that the processed waterbody flows through a first level, a second level...nlevel hydraulic power oxygenation constructed wetland successively and is exhausted after carrying out the n numbered level processing. The invention solves the problems of low dissolved oxygen level of constructed wetland matrix, sludge plugging of the matrix, unstable operation and the like, improves microorganism activity of the bed body, and forms a new sewage processing technology with high efficiency, stability, energy saving and perennial operation. The invention is suitable for the aspects of distributed domestic sewage processing, non-point source control, tail water processing of sewage plant, the waterbody ecological restoration engineering and zoology slope protection.
