面向污染物控制的大空间公共建筑防排烟系统设计研究

Design of Smoke Control and Exhaust System for Large Space Public Buildings Oriented for Pollutant Control

针对当前公共建筑防排烟系统排烟量小、速度慢的问题,研究一种面向污染物控制的大空间公共建筑防排烟系统。该系统设计分为两部分第一部分设计系统硬件,包括烟雾感应器、无线传输装置、微处理器、中央处理器以及排烟风机等设备。第二部分设计系统软件,即控制和协调计算机及外部设备程序。结果表明与传统防排烟系统相比,文章系统应用下,排烟量增大,排烟耗费时间缩短,速度更快,大气污染物排放量更少。通过该研究为火灾抢救和环境保护提供一定帮助,达到了研究目的。

Aiming at the problem of low smoke volume and slow speed in smoke control and exhaust system of public buildings,a smoke control and exhaust system for large space public buildings oriented to pollutant control is studied.The design of the system is divided into two parts:The first part designs the hardware of the system,including smoke sensor,wireless transmission device,microprocessor,central processor and exhaust fan.The second part designs the system software,which is the programs to control and coordinate the computer and external equipment.In order to test the feasibility and effectiveness of the system,an empirical analysis is carried out.The results show the smoke volume increases,the smoke exhaust time is shortened,the speed is accelerated and less air pollutants under the application of this system.This study can provide some help for fire rescue and environmental protection.
