Description
Technical field
This utility model relates to technical field of air purification, particularly relates to a kind of cabin new wind ozone conversion equipment.
Background technology
Aircraft cruises at stratosphere, and in air here, thing content is little, cloud layer is few, visibility is high.Containing relatively in stratosphere
The ozone of high concentration, it is possible to substantial amounts of absorption ultraviolet, preserve our planet on biology invade from the fatal of sunlight middle-ultraviolet lamp
Attack.But aircraft flies in cruising altitude, ozone enters cabin with the form of new wind out of my cabin, but become the major pollutants in cabin it
One.Research finds, ozone is to cause the principal element that personnel are uncomfortable in cabin.Before energy crises in 1973, the flight of aircraft is high
Degree is about in the range of 7 10km, and in cabin, ozone concentration is the lowest, and in cabin, air is almost all-fresh air supply, in cabin
Air quality is preferable, and ozone causes the discomfort of human body to be also introduced into the sight line of people.After energy crisis, disappear to save the energy
Consumption, aircraft flight height has brought up to 13.7km, and cockpit environmental control system uses the new wind of 50% and the return air of 50% to mix
The air supply pattern closed so that ozone enters cabin with the form of new wind out of my cabin.So far, after, the air quality problems in cabin is just
Progressively attract attention, the discomfort of health when increasing people starts to complain airplane.
Such as 1976, Pan American World Airway introduced a kind of novel commercial passenger aircraft Boeing-747 SP, and this type is because of chi
Very little little, lightweight and there is the advantages such as flying height is high, flight speed is fast, but frequently embraced by passenger in flight course
Resentment, occurs during mainly showing as taking coughing, breathe hard, the symptom such as even hemoptysis uncomfortable in chest.Monitoring finds, ozone is to cause
The key factor that engine hand is uncomfortable, in whole flight course, in cabin, ozone mean concentration is up to 0.86mg/m3, and 2 is little
Time meansigma methods be 1.39mg/m3, peak concentration is up to 2.34mg/m3.Many symptoms that passenger is showed, ozone is dense just
Spend caused by height.So far, the sight line being removed into people of ozone.It is essential that ozone converter has become as in aircraft flight
Parts.US Federal Aviation Administration (FAA) standard specifies: when aircraft flight height is higher than 5.5 km, ozone concentration in cabin
Peak value is less than 0.64mg/m3, and within two hours, interior average is less than 0.214mg/m3, and Qiang Zhiyaoqius execution.In order to reach FAA
The standard-required proposed, there has been proposed different methods and the ozone entered in cabin purifies to reach the rule of standard
Fixed.At present, major part aircraft is equipped with ozone converter, after being generally mounted to the compressor new wind bleeding point of aero-engine
Face.New wind is after compressor, and temperature raises, and its temperature range is between 150-210 DEG C, and the thermocatalytic removal for ozone provides
Necessary temperature conditions.
Ozone minimizing technology in early days includes the adsorption method of activated carbon, but activated carbon is from great, adds aircraft energy
Consumption, and adsorbing material existence absorption saturated characteristic, need to regularly replace filter element, virtually add the cost that ozone is removed.For
This, it has been proposed that employing ceramic honey comb or honeycomb are the load that carrier carries out catalyst, to reduce flowing resistance and ozone
The deadweight of transducer, but ceramic honey comb is frangible, and in flight course, impact resistance is poor, honeycomb carried catalyst preparation technology
Complexity, cost is high, and ozone goes a good appetite suddenly appearing in a serious disease poor effect at low concentrations.
