Online blockage removing gas pipe structure

The utility model discloses an online blockage removing gas pipe structure. The online blockage removing gas pipe structure comprises a front gas main pipe. The front gas main pipe is connected with one end of a descending pipe with a descending pipe valve, the other end of the descending pipe is connected with one end of a V-shaped slag depositing pipe, the other end of the slag depositing pipe 12 is connected with one end of an ascending pipe with an ascending pipe valve, the other end of the ascending pipe is communicated with a rear gas main pipe, and a slag discharging pipe with an outlet valve is arranged at the lowest position of the slag depositing pipe. A bypass pipe with a bypass valve is arranged between the ascending pipe and the descending pipe, and the bypass pipe is arranged above the descending pipe valve and the ascending pipe valve. The 90-degree included angle is formed by the front gas main pipe and the descending pipe, the 90-degree included angle is formed by the rear gas main pipe and the ascending pipe, the 90-degree included angle is formed by the bypass pipe and the descending pipe, and the 90-degree included angle is formed by the bypass pipe and the ascending pipe. Blockage in a fuel gas pipeline can be removed online without breaking the pipes or shutting down, many production problems caused by gas pipeline blocking can be effectively prevented, and the pipeline construction amount and the maintaining cost are greatly reduced.
