Abstract

The invention relates to the field of airport ground facilities, in particular to a deicing fluid hybrid heating device comprising a deicing fluid pipeline, a water pipeline and a heating boiler. The deicing fluid hybrid heating device is characterized in that the deicing fluid pipeline, an outlet of the water pipeline and a water inlet of the heating boiler are connected; a water outlet of the boiler is connected in parallel with an aloftwork arm spray gun and a ground spray gun; an inlet of the water pipeline is connected with a water tank; and an inlet of the deicing fluid pipeline is connected with a deicing fluid tank. Due to the arrangement of a clear water and deicing fluid hybrid heating device, the deicing fluid pipeline is connected in parallel with one water pipeline, the deicing fluid pipeline and the water pipeline are provided with a flowmeter and a variable pump which are linked, the mixing ratio of a deicing fluid and water can be controlled by a flow parameter set by a PLC (Programmable Logic Controller), and a deicing vehicle can regulate the concentration ratio and the temperature of the deicing fluid in real time according to different conditions and icing states of an airplane during deicing operation, thereby achieving the aims of reducing the consumption of the deicing fluid and increasing the reaction speed.

Description

technical field [0001] The invention relates to the field of airport ground equipment, in particular to a deicing liquid mixing and heating device, which is used for aircraft deicing vehicles to mix clean water and deicing liquid in proportion and heat them to a predetermined temperature. Background technique [0002] As we all know, the function of the aircraft deicing vehicle is to spray the deicing liquid heated to a certain temperature on the surface of the aircraft for deicing operations. Reduce de-icing fluid and energy consumption. [0003] At present, the deicing liquid heating device mainly adopts the preheating type, which first heats the water and indirectly heats the deicing liquid through the water. It can be electrically heated by the airport power supply in advance, and the heating time is sufficient; the disadvantage is that all the water and the deicing liquid are heated at one time. , when the amount of deicing fluid is small, heating energy is wasted; whe...
