A Harmful Gas Diffusion Control System in Underground Space

Abstract

The invention discloses a system for controlling diffusion of harmful gas in an underground space. The system comprises a harmful gas collecting part, a harmful gas emission part and an air feeding part, wherein the harmful gas emission part is used for emitting harmful gas, the air feeding part is used for conveying new air, the harmful gas collecting part comprises a main collecting body formedby splicing a plurality of collecting units, each collecting unit comprises a support, an air exhaust panel and a unit exhaust air collecting part which are arranged on the support, each air exhaust panel is provided with a plurality of air exhaust outlets, the unit exhaust air collecting parts communicate with the air exhaust outlets, every two adjacent unit exhaust air collecting parts communicate with each other, the system furthermore comprises a main air exhaust part which communicates with at least one unit exhaust air collecting part, and the air exhaust panels of the collecting units are spliced to form an operation platform top. The main collecting body is formed by splicing a plurality of collecting units, modularized design and integrated assembly are facilitated, the air exhaust panels forming the operation platform top are utilized for conducting air exhaust, the operation energy consumption is low, energy-saving operation of the underground space is achieved, and the environmental security of the underground space is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to an underground space harmful gas diffusion control system. Background technique [0002] Some special underground projects are responsible for the storage and detection of harmful substances. The traditional detection operation platform is an ordinary platform, and harmful substances are easy to emit a large amount of harmful gas during the detection process and spread to the entire underground space. Because some harmful substances are large in size and heavy, and require multiple people to detect and operate at the same time, traditional local exhaust devices such as fume hoods cannot meet this detection task. In order to replace harmful gases out of the underground space, a large amount of fresh air is required to replace them. The operating cost of the system is high, and harmful gases are easy to remain on the walls, vaults and floors of the underground space. It is diff...

Problems solved by technology

Due to the large size and heavy weight of some harmful substances, and the need for multiple people to detect and operate at the same time, traditional local exhaust devices such as fume hoods cannot meet this detection task

In order to replace the harmful gas out of the underground space, a large amount of fresh air is needed to replace it. The operating cost of the system is high, and the harmful gas is easy to remain on the walls, vaults and floors of the underground space, which is difficult to decontaminate and is not conducive to the physical and mental health of operators.
