Water draining and gas blocking structure of natural gas cabin of comprehensive pipe rack and comprehensive pipe rack
The invention discloses a water draining and gas blocking structure of a natural gas cabin of a comprehensive pipe rack and the comprehensive pipe rack. The water draining and gas blocking structure comprises a water drainage channel located below a firewall. The drainage channel comprises a water inlet part located on the first side of the firewall, a water outlet part located on the second side of the firewall and a water storage part connected with the water inlet part and the water outlet part. The drainage channel communicates with drainage side ditches on the two sides of the firewall, and the highest liquid level of the water inlet part is higher than that of the water outlet part. The water outlet part is provided with a gas blocking structure, the gas blocking structure comprises a water tank and an air blocking piece; the cross section of the water tank is gradually reduced from top to bottom in the height direction; a plugging opening is formed in the lower end of the water tank; and the air blocking piece is arranged in the water tank, and when water stored in the drainage channel is lower than the blocking opening, the air blocking piece can be located in the blocking opening to block the drainage channel. The drainage problem of the comprehensive pipe gallery natural gas cabin can be solved, the number of water collecting pits can be reduced, and meanwhile the hidden danger of natural gas leakage of adjacent fireproof partitions is eradicated.
本发明公开了一种综合管廊天然气舱的排水阻气结构及综合管廊，所述排水阻气结构包括：位于防火墙下方的排水通道；排水通道包括：位于防火墙第一侧的进水部分，位于防火墙第二侧的出水部分，以及连接进水部分和出水部分的存水部分；排水通道与防火墙两侧的排水边沟相连通，进水部分的最高液位高度高于出水部分；出水部分设置有阻气结构，阻气结构包括：水槽，水槽沿着的横截面沿着高度方向自上而下逐渐减小；水槽的下端设置有封堵口；阻气件，设置在水槽内，当排水通道内存水低于封堵口时，阻气件能位于封堵口，封堵排水通道。本发明既能解决综合管廊天然气舱排水问题，又能减少集水坑，同时杜绝相邻防火分区天然气泄漏的隐患。
