The invention discloses an urban underground utility tunnel system capable of carrying out safety protection by nitrogen. The system comprises a nitrogen supply device (10), a nitrogen conveying pipeline (20) and an underground utility tunnel (30), wherein the nitrogen supply device (10), the nitrogen conveying pipeline (20) and the underground utility tunnel (30) are connected in sequence; the nitrogen conveying pipeline (20) is provided with a nitrogen control valve; and the nitrogen conveying pipeline (20) can convey nitrogen in the nitrogen supply device (10) into the underground utility tunnel (30). The urban underground utility tunnel system capable of carrying out the safety protection by the nitrogen simultaneously has two functions of electric cabin fire extinguishment and naturalgas cabin explosion suppression. Compared with a hot aerosol and superfine dry powder fire extinguishment system, the system disclosed by the invention has the advantages that investment is low and fire extinguishing agents can be permanently stored, do not lose efficacy and do not need to be replaced. Compared with a CO2 fire extinguishment system, the system disclosed by the invention has the advantages of low investment and high safety for people and has an extremely good prospect.
本发明公开了一种采用氮气进行安全保护的城市地下综合管廊系统，包括依次连接的氮气供气装置(10)、氮气输送管道(20)和地下综合管廊(30)，氮气输送管道(20)上设有氮气控制阀门，氮气输送管道(20)能够将氮气供气装置(10)内的氮气输送至地下综合管廊(30)内。该采用氮气进行安全保护的城市地下综合管廊系统同时具有电舱灭火及天然气舱抑爆两种功能，相比热气溶胶及超细干粉灭火系统具有投资低、灭火剂可永久储存不失效不需要更换的优势，相比CO灭火系统具有投资低、对人安全性高的优势、极具前景。
