Hydrogen ion negative pressure exhaust device for isolating ward

Abstract

The invention discloses a hydrogen ion negative pressure exhaust device for isolating a ward. The device comprises a purification exhaust mechanism, a filtering mechanism and a negative pressure exhaust mechanism which are sequentially arranged outside the ward in the longitudinal direction, and the purification exhaust mechanism comprises a first exhaust mechanism, a spiral extension pipe, a second exhaust mechanism and an air quality sensor; a plurality of photo-hydrogen ion purifiers are arranged at the air outlet end of the first exhaust mechanism; and the air quality sensor is fixedly arranged between the second exhaust mechanism and the spiral extension pipe. Firstly, the negative pressure exhaust mechanism is provided with a first fan blade and a second fan blade which rotate coaxially and reversely, air can be exhausted outwards with large wind power, and then negative pressure is generated to suck out indoor air; and secondly, air is purified through a photo-hydrogen ion purifier and an activated carbon filter disc, and meanwhile, the air quality sensor and a controller are arranged to adjust the air speed of the first air exhaust mechanism and the second air exhaust mechanism, so that the purification duration of toxic air in the spiral extension pipe is properly prolonged.

Description

technical field [0001] The invention relates to the field of exhaust, in particular to a hydrogen ion negative pressure exhaust device for isolation wards. Background technique [0002] The so-called negative pressure ward means that under special equipment, the air pressure in the ward is lower than the air pressure outside the ward. In this case, in terms of air circulation, only fresh air from outside can flow into the ward, and the ward is kept clean. The air polluted by patients will not leak out, but will be discharged to a fixed place in time through a special channel. [0003] Exhaust devices in traditional isolation wards have the following deficiencies: [0004] First, the exhaust volume of the traditional exhaust device may be insufficient to generate enough negative pressure to discharge the toxic gas in the ward from the special channel; [0005] Second, the ability of the traditional exhaust device to purify the air is not strong, and some toxic gases may be ...

Problems solved by technology

[0004] First, the exhaust volume of the traditional exhaust device may be insufficient to generate enough negative pressure to discharge the toxic gas in the ward from the special channel;

[0005] Second, the ability of traditional exhaust devices to purify the air is not strong, and some toxic gases may be directly discharged into the atmosphere, resulting in certain pollution
