This utility model relates to the field of experimental equipment and provides a permeation purification device. The device includes a heating plate with a positioning hole (11) for placing a purification vessel. The purification vessel has a cup-shaped wall with multiple layers of filter media at its bottom. A Teflon permeation layer is placed on the top layer of the filter media, and a leak-proof layer is placed below the Teflon permeation layer. A leakage hole is located in the center of the leak-proof layer. The device also includes a pressurizing device that can movably cover the upper opening of the purification vessel. This utility model uses pressurized permeation to remove impurity-containing solvent, ensuring thorough solvent removal. During operation, operators have minimal contact with the purification vessel, keeping them away from chemical solvents and effectively protecting their health.

The application relates to the technical field of coal seam permeability improvement, and provides a deep coal seam combined permeability improvement method and system. The combined permeability improvement method comprises the following steps: according to obtained coal seam parameters of a target coal seam, drilling two empty holes and a fracturing hole in the target coal seam; the two empty holes and the fracturing hole are located in the same horizontal coal seam; performing three times of grouting and hole sealing on the target coal seam; after the hole sealing is completed, performing once of hydraulic fracturing on the target coal seam, so that new fractures are generated in the target coal seam after the hydraulic fracturing; and adopting an air gun to cyclically perform high-pressure air pulse on the target coal seam to expand the fractures. Therefore, the development scale of the fractures is better increased, the gas enrichment area and the extraction blank area are reduced, the permeability improvement effect of the coal seam is better, the range is larger, and gas extraction is more thorough.

This invention discloses a bus control method, a bus snow removal and drainage system, a bus, and a storage medium. The bus control method includes a bus with a suspension system and a drainage structure installed on the bus floor. The method includes: acquiring information about the vehicle's surrounding environment and road conditions; determining that the surrounding environment information meets a drainage threshold condition; and controlling the drainage structure and / or the suspension system based on the road conditions. This bus control method improves drainage efficiency within the vehicle, resulting in more thorough drainage and enhanced passenger experience and comfort.
