A building-type public flue system and its airtightness detection method

Abstract

A building-type public flue system, a gas generating device is installed outside the bottom of the public flue, and a smoke generator and a first flow rate are sequentially installed on the pipeline between the gas outlet of the gas generating device and the gas inlet of the public flue. Sensors, the second flow sensor is installed on the top of the public flue, the first smoke sensor is installed in the smoke pipe, the second smoke sensor is installed in the kitchen of each floor, and it also includes a sensor that can read the first flow Sensor, the second flow sensor, the first smoke sensor and the signal of the second smoke sensor to judge whether the public flue system is leaking or not. The controller of the building-type public flue system can intelligently judge whether the public flue system is leaking by reading the signals of the first flow sensor, the second flow sensor, the first smoke sensor and the second smoke sensor. The specific leakage location of the public flue system and the judgment method are simple and reliable.

Description

technical field [0001] The invention relates to a central flue system, in particular to a building-type public flue system and a detection method thereof. Background technique [0002] At present, the floors of newly-built buildings in cities are generally higher and higher, and they are mainly decorated with engineering. Most high-rise residences use indoor range hoods, smoke pipes, fire check valves and public flues to connect them, so that the cooking fumes in the kitchen can pass through the smoke pipes. It is discharged into the public flue, and the sealing performance of the public flue directly affects the smoke exhaust effect of the flue system. At present, most of the problems of "smoke leakage" in public flues in buildings are caused by cracks in public flues or poor installation of fire check valves. For the problem of "smoke leakage" in public flues, most of them can only be monitored manually at present, and judge whether the public flues are "smoke leaking" th...

AI Technical Summary

Problems solved by technology

This method of manual monitoring of oil fume leakage is time-consuming and laborious. For complex flue environments, it is easy to misjudgment, and the public flue of high-rise residential buildings is long, the site environment is relatively complicated, and it is difficult to find the leakage point. If there is "smoke leakage", Not easy to detect manually
