Pipe gallery explosion venting interval measurement device and measurement method thereof

Abstract

The invention relates to a pipe gallery explosion venting interval measurement device and a measurement method thereof. The measurement device comprises a vacuum pump, a rotary valve, a pipe gallery, explosion venting openings, manhole covers, weights, a pressure gauge, an ignitor, a gas storage bottle, a knob valve, a pressure reducing valve, a pressure gauge and a rotary valve, wherein the vacuum pump is connected with the rotary valve, one end of the rotary valve is connected with the pipe gallery, the pipe gallery is provided with openings adopted as the explosion venting openings, the pipe gallery is also provided with the manhole covers and the weights, the manhole covers cover the explosion venting openings, the pipe gallery is further provided with the first pressure gauge and the ignitor, the gas storage bottle is provided with the rotary valve, the pressure reducing valve and the second pressure gauge sequentially, and the gas storage bottle is connected with the pipe gallery through the rotary valve. With the pipe gallery explosion venting interval measurement device and the measurement method thereof of the invention adopted, an appropriate explosion venting interval can be determined, so that requirements for the safety of explosion venting can be satisfied, and at the same time, fewer explosion venting openings are adopted, so that economical performance can be realized.

Description

technical field [0001] The invention belongs to the technical field of gas explosions in narrow and long spaces, and relates to a measuring device and a measuring method for the explosion venting distance of a pipe gallery. Background technique [0002] With the acceleration of urbanization, urban underground pipelines are getting closer and closer to densely populated and important buildings such as residential areas, factories and schools, while criss-crossing and intricate underground pipeline corridors are laid with various important and important buildings such as oil and gas, gas, etc. Dangerous pipelines, once an explosion accident occurs, will cause huge casualties and bad social impact. The problem of insufficient safety distance of oil and gas pipelines will continue to exist for a long time, and when oil and gas leak into the pipeline gallery and gather and explode, it will inevitably pose a serious threat to the safety of the people. In order to reduce the serio...

AI Technical Summary

Problems solved by technology

[0003] Existing studies have done a lot of research on the explosion venting characteristics and devices of cylindrical pipes, such as the discussion on the influence of explosion venting methods on the explosion venting pressure, such as the research on the effect of explosion venting area on the pressure of the explosion venting process of cylindrical vessels, but there is no To study the determination of the appropriate explosion venting distance for the underground pipe gallery, for this reason, a device and method for measuring the explosion venting distance of the pipe gallery are needed to solve the above-mentioned problems in the prior art, so that it can determine the appropriate explosion venting distance. distance, so as to meet the safety requirements of explosion venting, and at the same time, set less explosion venting ports to meet the requirements of economy
