Airplane deicing fluid proportioning device adopting electrical heating

Abstract

The invention discloses an airplane deicing fluid proportioning device adopting electrical heating, which is characterized in that pipelines of a deicing fluid storage tank system and an electrical heating water storage tank system are connected in series; the respective components and arrangement of the two systems are basically same; the two systems are successively connected with electrical valves, variable frequency governor pumps, temperature sensors, flow sensors, pressure sensors, and the like; the pipelines of the two systems are connected through the first flow sensor and the second flow sensor; water and low-temperature deicing fluid adopting electrical heating are mixed; the water storage temperature can be adjusted by adjusting electrical power; and the temperature sensors, the pressure sensors, the flow sensors, the variable frequency governor pumps, and the like are connected to a programmable controller through output signals. The airplane deicing fluid proportioning device has the advantages of high efficiency, environment pollution reduction, resource saving, and subsequent maintenance and operation cost reduction. Meanwhile, personnel in airports can flexibly set the deicing fluid and water proportion, the outlet temperature, the flow, the flow rate, and the like by means of a key mode according to the current weather condition.

Description

technical field [0001] The invention belongs to aircraft maintenance equipment, in particular to an aircraft deicing fluid heating and proportioning device for airports. Background technique [0002] The icing / snow / frost on the ground of the aircraft poses a serious safety hazard to the safe flight of the aircraft. In order to ensure the safe flight of the aircraft and the normal and efficient operation of the airport flight, spraying deicing fluid and other chemicals on the surface of the aircraft has become an effective way to clear the surface of the aircraft. method of ice / snow / frost and other pollutants. Aircraft deicing fluid is a high-viscosity liquid. In order to lower the freezing point and prolong the retention time after deicing, the deicing fluid must be mixed with a certain proportion of water. The specific mixing ratio depends on the thickness of the ice on the surface of the aircraft and depends on ambient temperature. [0003] At present, most of the deicin...

Problems solved by technology

Whether the heating method is fuel oil heating or steam heating, there are major disadvantages: fuel oil heating aggravates environmental pollution, and is not conducive to energy saving and emission reduction; the use of hot water provided by the heating center requires the establishment of deicing fluid heating Compared with the matching system, the construction cost is high, and the follow-up maintenance also requires high costs. It is difficult to obtain due and promotion in some small and medium airports
