Smoke-removing wave-absorbing flame-retardant device and underground protection engineering with smoke-removing wave-absorbing flame-retardant device

Abstract

The invention relates to the technical field of underground protective engineering, and discloses a smoke removing, wave absorbing and flame retarding device which comprises an outer box, an inner box, a smoke inlet pipe, a fixed plate and a movable plate. The inner box is arranged in the outer box, one end of the smoke inlet pipe is located on the outer side of the outer box, the other end of the smoke inlet pipe penetrates through the side wall of the outer box to be communicated with the inner box, the fixed plate is connected with an opening in the bottom end of the inner box and extends towards the inner wall of the outer box, a gap is formed between the fixed plate and the bottom of the outer box, and the movable plate is arranged above the fixed plate in a floating mode and provided with a plurality of first air holes. A plurality of first air holes are formed in the outer box, a plurality of second air holes are formed in the movable plate, and the first air holes and the second air holes are staggered, so that when the movable plate sinks to be in contact with the fixed plate, the first air holes and the second air holes shield and seal fluid flow in the outer box, dust removal liquid is arranged in the outer box and the inner box, and a smoke outlet is formed in the outer box. The invention further discloses a power station with the power station, and the power station has the beneficial effects that the damage such as low-pressure quick combustion (detonation) and expansion while blasting is effectively defended.

Description

technical field [0001] The invention relates to the technical field of underground protection engineering, in particular to a smoke-removing, wave-eliminating, and flame-retardant device and an underground protection engineering equipped with the same. Background technique [0002] Underground protection projects, including but not limited to national defense projects, civil air defense projects, reconnaissance projects, communication projects, underground power stations, water supply stations, etc. Fuel-fired power stations involved in underground protection works include but are not limited to internal combustion engines fueled by gasoline, diesel, and heavy oil. After the internal combustion engine unit is started, the temperature of the flue gas is as high as 400-600°C. After being discharged from the underground protection project, a high temperature difference will be generated with the surrounding area. In addition, the underground working conditions are harsh and the...

Problems solved by technology

The shock waves of these weapons can enter the interior of the project along the hole, killing personnel and destroying equipment; when the weapon burns into the project, it will ignite the internal combustibles, causing a secondary explosion (explosion), exhausting oxygen, killing personnel, and destroying equipment

[0004] At present, the dust removal and wave suppression facilities set up in underground protection projects have relatively single functions, need to be converted from peacetime to wartime, and have weak defense against temperature and pressure (cloud explosion) weapons, etc.

Taking civil air defense engineering power stations as an example, some dust removal devices have uneven performance and no anti-shock wave performance; Detonation), explosion while expanding, etc.
