Processing method for responding public building indoor burst air pollution

Abstract

The invention provides a processing method for responding public building indoor burst air pollution. The processing method comprises the following steps: establishing a computational fluid kinetic model to simulate the dynamic concentration distribution of burst air pollution under conventional ventilation; dividing a computational region on a mock object; obtaining personnel dynamic distributionrule of the computational region through a multi-main body model software; computing air pollution accumulative exposure risk according to the dynamic concentration distribution and the personnel dynamic distribution; determining an optimal function model to obtain a ventilating key protection region; determining an air pollution concentration design threshold of the ventilating key protection region; reversely matching according to the optimal function model to obtain an emergency ventilating scheme; and checking the emergency ventilating scheme till to finally output the ventilating security region. The corresponding emergency ventilating scheme and an operation control measure are reversely matched through the air pollution concentration design threshold, thereby constructing the ventilating security region in the public building, and the security and the health of the public building indoor personnel can be maximally guaranteed in the burst air pollution.

Description

technical field [0001] The invention belongs to the technical field of building ventilation safety area design, and in particular relates to a treatment method for sudden indoor air pollution in public buildings. Background technique [0002] Since most public buildings are crowded with people, people may become potential targets of terrorists. There are many ways to attack public buildings, but the attack method of releasing biological and chemical warfare agents inside public buildings is relatively secretive, and once released may lead to disastrous consequences. When important public buildings are facing the risk of such attacks, how to create a ventilated safe area in the building through the effective organization of emergency ventilation, so that the safe area can still guarantee evacuation to the safe area even when facing the most unfavorable attack scenarios Indoor personnel are exposed to a lower pollution concentration, which is a technological innovation that u...

AI Technical Summary

Problems solved by technology

Its concept is similar to civil air defense ventilation and accident ventilation, but due to the randomness of biochemical attacks, it is first necessary to determine the possible indoor pollution exposure concentrations of indoor personnel caused by different attack scenarios, and due to the organization of indoor personnel evacuation, it is also necessary to obtain The dynamic distribution of indoor personnel, the above dynamic data can be obtained through prior simulation with existing simulation software, but there is no method to quantify the exposure risk of indoor personnel by considering the dynamic changes of indoor air pollution concentration and the dynamic distribution of indoor personnel at the same time

Moreover, there is currently no public technology that can be used as a reference for the bidirectional optimization problem of the coupling of the ventilation safety area.
