The invention discloses a gas mixing control device for an LPG (Liquefied Petroleum Gas) generator set, which relates to the technical field of generator set operation control, and comprises a gas engine for realizing accurate mixing proportion control under the matching of a proportion dynamic response component, predicting the optimal gas mixing proportion and flow demand under the current working condition, and controlling the gas engine to operate according to the optimal gas mixing proportion and flow demand. When the propane content in the LPG is increased, the model prediction controller properly reduces the gas inflow and increases the air amount, sufficient combustion is ensured, the mixing proportion and flow can be rapidly corrected, the combustion process is rapidly recovered to be stable, it is ensured that the gas engine stably operates under different loads, the whole device forms flow balance and stable operation, and the service life of the gas engine is prolonged. Under different gas sources and LPG component differences, effective components actually participating in combustion are accurately judged, so that the needed gas and air amount is accurately calculated, accurate mixing proportion control is achieved, and meanwhile accurate control over the mixed gas mixing process is achieved under the cooperation of an adjusting control assembly.

The present invention discloses an automatic interception, flushing and dosing device for a drainage pipe, which relates to the technical field of drainage pipe water treatment, and includes a rotating weir plate, a seal, a drainage pipe, a starting component and a dosing component. The rotating weir plate and the seal cooperate to intercept sewage with low flow rate and small flow. When the sewage upstream of the rotating weir plate accumulates to a set water level, the starting component starts the drainage pipe to drain the sewage and quickly suck the sewage and alluvial materials upstream of the rotating weir plate to the downstream of the rotating weir plate. The rotating weir plate and the dosing component cooperate to realize the automatic rotation and resetting of the rotating weir plate. The dosing component can adjust the dosage of the dosing according to the water flow rate of the drainage pipe. For the diversion rainwater pipe with mixed sewage, the present invention can prevent the formation of sediments in the drainage pipe in the dry season, and reasonably and automatically dosing the water flow in the rainy season, so that the mixing ratio of the agent and rainwater remains stable.

The invention belongs to the technical field of water treatment mixing and proportioning, and particularly discloses and provides an automatic reverse osmosis RO water and softened water mixing and proportioning control system which is characterized in that the turbulent energy coefficient of mixed water is constructed by monitoring the fluid state of reverse osmosis RO water and softened water; the water quality component ratio of the RO water and the softened water is determined by detecting each water quality component of corresponding water inlet pipes of the RO water and the softened water; by monitoring the water quality change of the mixed water, the pressure loss function of the mixed water in the mixing tank is analyzed, the mass transfer coefficient of the mixed water in the mixing tank is constructed, and an important basis is provided for optimizing the mixing process; by intelligently regulating and controlling the opening degrees of flow valves of reverse osmosis RO water and softened water, finely adjusting the proportion according to water quality parameters monitored in real time, and meanwhile, changing the corresponding limit value of the mixing regulation and control proportion of the reverse osmosis RO water and the softened water, the mixing proportion of the reverse osmosis RO water and the softened water is favorably optimized, and the stable operation of the system is maintained.
