2results about How to "Does not affect normal production" patented technology

The application discloses a petrochemical park gas leakage monitoring and positioning method, comprising the following steps: determining the downwind boundary of the target park dominant wind direction as a monitoring boundary, and obtaining the light path integral concentration data and meteorological data on the monitoring boundary; reconstructing the light path integral concentration data, and obtaining a self-checking result according to the reconstruction result; and determining the position of a leakage source based on an optimization algorithm inversion according to the self-checking result. The application also discloses a petrochemical park gas leakage monitoring and positioning system, an electronic device and a storage medium. The application cooperates the monitoring boundary design and the active optical monitoring with the meteorological data, performs self-checking based on the light path integral concentration reconstruction, and then determines the leakage source through the optimization algorithm inversion. The application has strong implementability, can quickly and accurately position the leakage source under the premise of not affecting the normal production of the petrochemical park, and provides reliable guidance for subsequent emergency disposal.

The invention discloses a mobile gangue slurry preparation unit in a mine, comprising a material preparation and conveying unit, which is connected with a feeding unit through a quantitative feeder. The invention also discloses a method for preparing the gangue slurry using the unit, comprising the following steps: step 1, using a material transfer belt to sequentially convey and fill a plurality of bin bodies with gangue powder; step 2, the bin bodies convey the gangue powder to the material transfer roller through a discharge port; step 3, the material transfer roller conveys the gangue powder to the quantitative feeder, which conveys the gangue powder into the communicating overflow mixer; step 4, opening the quantitative water supply system to supply water to the communicating overflow mixer for mixing, and the mixed gangue slurry is conveyed to the grouting and filling pump through the discharge port; step 5, the grouting and filling pump pumps the gangue slurry to the underground goaf. The gangue slurry preparation unit solves the problem of interruption in the gangue slurry conveying in the existing preparation technology.
