Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ventilation systems, in particular to a people's air defense and fire dual-purpose ventilation system provided with a filter ventilation system. BACKGROUND

[0002] The ventilation system of a people's air defense project is one of the most important core systems, which not only guarantees the air quality and comfort during normal use, but also provides clean air for shelter personnel and maintains the necessary overpressure inside the project to prevent the infiltration of external contaminated air and protect the safety of personnel in wartime or when subjected to nuclear and biological weapons attacks.

[0003] Currently, the ventilation system of a people's air defense project is generally set up independently in normal and wartime modes, that is, the ventilation system and equipment are set up independently in normal and wartime modes, the vertical shaft, ventilation port and machine room are set up independently, and only the ventilation pipeline system in the main body of the project is shared. Under this mode, the equipment in the air defense area occupies a large area, the daily maintenance workload of the ventilation equipment is extremely heavy, and the conversion workload during the conversion between normal and wartime is also relatively large. At the same time, since only the ventilation equipment used in wartime is maintained daily without being used, some projects have problems such as wartime ventilation equipment being out of repair, damaged or even destroyed and removed, which seriously restricts the full play of the wartime protection efficiency of people's air defense projects.

[0004] Disadvantages of the independent setting mode of normal and wartime ventilation systems:

[0005] The ventilation equipment occupies a large area in the project: the normal ventilation system needs to be set up with a gas collection chamber and a ventilation machine room, and the wartime ventilation system needs to be set up with a diffusion chamber, a dust removal chamber, a filter chamber and a ventilation machine room, and the total area occupied by the equipment rooms is about 100 square meters, which is contrary to the demand for intensive and efficient use of underground space;

[0006] Poor economic efficiency: a large number of fans are used, which results in repeated investment, and because the ventilation equipment occupies a large area in the project, the number of parking spaces available during normal use is reduced, which reduces the economic efficiency during normal use;

[0007] Damaged wartime protection efficiency: the wartime ventilation equipment is idle for a long time during normal use, and lacks effective preventive maintenance means, resulting in a large number of equipment damage or even removal, which seriously damages the wartime protection efficiency of people's air defense projects;

[0008] Complex and inefficient conversion between normal and wartime: manual switching of the on-off of the air valves in the normal and wartime machine rooms according to the system diagram and the plane layout is required, which is complex and time-consuming, therefore, an improved technology is needed to solve the problem in the prior art.
