Abstract

The invention relates to a deicing fluid heating and mixing device, which belongs to the field of airport ground equipment. The device comprises a boiler and a deicing fluid pipeline, and is characterized in that: a water outlet of the boiler is a parallel-connected loop with one path connected with a water tank and the other path connected with a deicing fluid heating pipe coil, a water inlet of the boiler is connected with the water tank, and the water outlet of the boiler is connected with a hot water pipeline through a retaining valve and a tee joint, the hot water pipeline and the deicing fluid pipeline are parallelly connected at outlets of the retaining valves thereof, a unidirectional deicing fluid branch is arranged between the deicing fluid pipeline and a safe deicing fluid loop, and a unidirectional water outlet branch is arranged between a water inlet pipeline and a safe water outlet loop of the boiler. As the deicing fluid heating and mixing device has a heating and mixing device of the clean water and the deicing fluid, the deicing fluid pipeline is parallel connected with the hot water pipeline, and a flow meter and a variable pump that are coupled are arranged on the deicing fluid pipeline and the hot water pipeline, the concentration proportion of the deicing fluid can be adjusted instantaneously according to different environments and airplane icing conditions, and consequently the goal for reducing the consumption amount of the deicing fluid can be achieved.

Description

technical field [0001] The invention relates to an airport ground equipment, in particular to a deicing fluid heating and mixing device, which is used in an aircraft deicing vehicle to heat clean water and deicing fluid and adjust the mixing ratio during deicing operations. Background technique [0002] As we all know, the function of the aircraft deicing vehicle is to spray the deicing fluid heated to a certain temperature onto the surface of the aircraft through the spray gun for deicing operation. Depending on the ambient temperature and the icing condition of the aircraft, different concentrations and temperatures of the deicing fluid can be used. , to reduce deicing fluid consumption. [0003] At present, the deicing fluid spraying device is mainly composed of a single deicing fluid pipeline, which is characterized by simple pipeline and reliable performance. Instant adjustment of ice liquid concentration. [0004] Because the existing deicing fluid spraying device ha...
