Abstract
An electric-heating airplane deicing system comprises a vehicle-mounted platform, deicing liquid, a deicing liquid box, a deicing liquid pump, an electric-heating boiler and a deicing liquid spraying and atomizing device. The electric-heating airplane deicing system is characterized in that the deicing liquid includes ethylene glycol, propylene glycol, potassium formate, dipotassium phosphate and a surfactant, and the surfactant is linear alkylbenzene sulfonate. The electric-heating boiler is adopted, so that more quickness and more convenience in operation are realized, and higher efficiency and more safety are realized. In addition, due to the deicing liquid, airplane deicing efficiency is improved, and environmental pollution is reduced.
Description
Technical field
The present invention relates to a kind of electro heat aircraft deicing system, relate in particular to a kind of Instant heating type aircraft deicing system of using deicing liquid.
Background technology
In the last few years, along with China's expanding economy, Civil Aviation Industry was rapid, and no matter aviation transport has entered the ranks of civil aviaton big country from people's business amount or fleet scale Shang Kan， China.During the special weathers such as airport or the airline company that is positioned at cold district runs into rain, snow in the winter time, temperature is low, air humidity is large, aircraft can be tied on its surface one deck frost or ice, aircraft freezes and can make the aerodynamic performance of aircraft degenerate, the lift of aircraft is reduced, resistance increases, and affects safety and the operability of aircraft, so must remove in time, avoid hidden danger, so aircraft deicing system is the aircraft safe in operation support equipment of cold district airport or airline company's indispensability.Aircraft deicing system is divided into two classes by principle of work: a class is circulating heating type aircraft deicing system, and this class deicing vehicle inefficiency, energy dissipation are larger, have been tending towards superseded; Another kind of is Instant heating type aircraft deicing system, and this ice removal system is that the deicing liquid extracted out by centrifugal pump is directly heated to higher than 80 ℃ and penetrated by spray gun, and deicing liquid is heated to liquid to be raised to the temperature required time shorter from starting, and its deicing efficiency is improved.But it conventionally uses especially heating boiler of diesel oil of fuel oil, due in ice detachment, the frequent appearance of fuel Heating boiler cannot normal ignition or situation about midway extinguishing, and is therefore difficult to guarantee safe, the efficiently operation of aircarrier aircraft under icy conditions in winter.
Summary of the invention
The present invention is intended to overcome difficulty of the prior art, a kind of more efficient and safe aircraft deicing system is provided, this system comprises vehicular platform particularly, deicing liquid, deicing liquid case, deicing liquid pump, electrically heated boiler and deicing liquid jet atomization device, it is characterized in that deicing liquid comprises ethylene glycol, propylene glycol, potassium formate, dipotassium hydrogen phosphate and inhibiter, described inhibiter is sodium n-alkylbenzenesulfonate, ethylene glycol wherein, propylene glycol, potassium formate, the part by weight of dipotassium hydrogen phosphate and sodium n-alkylbenzenesulfonate is: 10:8:6:1:1, or be 15:10:9:1:1.
Preferably, the electric energy that electrically heated boiler can be used airport to provide, the electric energy that also can adopt vehicular platform to provide.
Preferably, electrically heated boiler for example comprises spiral fashion or the latticed heating wire being in boiler space.
Because the present invention adopts electrically heated boiler, therefore operate more quick and convenient, the while is more efficient and safety also.And the present invention also improves for the deicing liquid using, and has improved aircraft deicing efficiency, has reduced environmental pollution.
The specific embodiment
According to aircraft deicing system of the present invention, comprise vehicular platform, deicing liquid, deicing liquid case, deicing liquid pump, electrically heated boiler and deicing liquid jet atomization device.Deicing liquid pump is pumped to electrically heated boiler by deicing liquid from deicing liquid case, and deicing liquid is for example heated to more than 86 degrees Celsius at electrically heated boiler, then from deicing liquid jet atomization device, sprays.The unlatching of electrically heated boiler and watt level are all controlled by automatic temperature-adjusting control system, and the unlatching of electrically heated boiler is monitored and then controlled to the opening and closing of deicing liquid jet atomization device and the size variation of injection flow all by automatic temperature-adjusting control system or close and regulate electrical heating power size, thereby guarantee that the temperature of deicing liquid reaches requirement.Electrically heated boiler can for example comprise spiral fashion or the latticed heating wire being in boiler space, and electrically heated boiler will be very rapidly with even when deicing liquid is heated like this.Wherein electrically heated boiler can be used the electric energy that airport provides, the electric energy that also can adopt vehicular platform to provide.With respect to existing oil burning boiler, the use of electrically heated boiler makes to operate more quick and convenient, and the while is more efficient and safety also, and the structure of electrically heated boiler is also relatively simple.
Preferably, the deicing liquid that aircraft deicing system according to the present invention comprises comprises ethylene glycol, propylene glycol, potassium formate, dipotassium hydrogen phosphate and inhibiter; Their part by weight is: 10:8:6:1:1, or be preferably 15:10:9:1:1.
Preferably, the inhibiter adopting is sodium n-alkylbenzenesulfonate.
Deicing liquid according to the present invention has reduced the use of polyalcohol, and not containing nonylphenol or octyl phenol, more friendly to environment.
Those skilled in the art can make and replacing or modification content of the present invention according to content disclosed by the invention and the art technology of grasping; but these replacements or modification should not be considered as departing from the present invention's design, and these replacements or modification are all in the claimed interest field of the present invention.
