The present application relates to the technical field of coal mine energy utilization, and particularly relates to an oxidation device, an oxidation method and an oxidation power generation method for low-concentration coal seam gas. The device comprises a shell, a gas distribution plate, a fixed tube plate and a plurality of heat exchange tubes arranged in the interior of the shell; wherein the gas distribution plate and the fixed tube plate sequentially divide the interior of the shell into an air inlet buffer zone, a gas transmission and heat exchange zone and a combustion zone, and the plurality of heat exchange tubes are arranged in the gas transmission and heat exchange zone and communicate with the air inlet buffer zone and the combustion zone. The low-concentration coal seam gas can be rapidly and continuously oxidized, the oxidation efficiency is high, the device can be continuously and stably operated, the operation process is simple, and the cost is saved.

This application discloses a port route planning method, system, device, and storage medium based on virtual lanes. First, based on a pre-built lane grid index, the starting and ending lanes of the target vehicle are quickly located. Second, based on the obstacle and structural information of the current lane, a set of key lane-changing points formed by obstacles and / or process constraints is extracted. Then, the actual lanes and the virtual lanes generated based on the key lane-changing points are used together as graph nodes, and a weighted topology graph is constructed with travel cost as the edge weight. Next, the optimal path from the starting lane to the ending lane, passing through all key virtual lane nodes in sequence, is obtained based on the shortest path algorithm. Finally, the optimal path is converted into an executable path point sequence containing the key lane-changing points. This method can efficiently adapt to the dynamic operating environment and process constraints of ports, improving the flexibility and efficiency of route planning.
