Airfield runway ice and snow melting device

Abstract

The invention discloses an ice and snow melting device for an airport runway. It has an airport runway. The airport runway includes a runway base layer and a runway surface layer. A heat dissipation system is arranged between the runway base layer and the runway surface layer. The heat dissipation system and The heat source system is connected, and the heat source system includes a circulation pump and a heat source; the heat dissipation system is composed of a finned cooling pipe, an oil inlet main pipe, an oil return main pipe and a pipeline, and the outlet end of the oil return main pipe of the heat dissipation system is connected to the oil return port of the heat source. Connected, the pipe body of the oil return main pipe is respectively connected with the outlet ends of a plurality of fin heat dissipation pipes, the inlet end of the fin heat dissipation pipes is connected with the outlet end of the oil inlet main pipe, and the inlet end of the oil inlet main pipe is connected with the circulation The outlets of the pumps are connected, and the inlets of the circulating pumps are connected with the outlets of the heat source through pipes. The invention can overcome the problem that the normal flight of the aircraft is affected by ice and snow or freezing fog on the airport runway, saves energy, has the characteristics of simple equipment structure, fast ice and snow melting speed, long service life and the like.

Description

technical field [0001] The invention relates to ice-melting and snow-melting facilities in an airport, in particular to an ice-melting and snow-melting device for an airport runway. Background technique [0002] The main reason affecting the safety of aircraft take-off and landing is that the ground temperature suddenly drops due to strong cold air at the airport and the runway to form ice and snow. The loss of friction on the runway prevents the aircraft from taking off normally, which has a great impact on flight safety and normal operation. The existing snow and ice removal facilities are difficult to remove the frozen snow and ice in the road surface grooves; and the various cleaning and deicing methods equipped at the airport are mainly divided into the following categories: 1. Use snow removal equipment: snow blower, snow pusher (Bulldozers), forklifts, etc., in case of ice and snow weather, a number of snow blowing vehicles are used for blowing. The snow blowing vehic...

Problems solved by technology

[0002] The main reason affecting the safety of aircraft take-off and landing is that the ground temperature suddenly drops due to the strong cold air at the airport and the runway to form ice and snow. The runway loses friction and the aircraft cannot take off normally, which has a great impact on flight safety and normal operation.

The existing snow and ice removal facilities are difficult to remove the frozen snow and ice in the road surface grooves; and the various cleaning and deicing methods equipped at the airport are mainly divided into the following categories: 1. Use snow removal equipment: snow blower, snow pusher (Bulldozers), forklifts, etc., in case of ice and snow weather, a number of snow blowing vehicles are used for blowing. The snow blowing vehicles are all refitted with fighter jets. , the fuel consumption is very high, and multiple refueling trucks are needed to refuel the snow blower at any time. The 3,400-meter-long runway of the airport needs to be blown once, and it will cost more than 300,000 to 500,000 yuan.

If you use forklifts, snow carts and other equipment to remove ice and snow, it takes a long time to remove ice and snow, and the removal of ice and snow is not complete; 2. Although the use of snow melting agents can quickly melt ice and snow, it will pollute the environment, corrode the runway, and reduce the use of the runway Defects of life

3. Laying electric heating and other equipment in the airport runway, the equipment structure is complex, the overall construction is complicated, the investment is high, and the safety is poor; Long-term operation is required, resulting in energy waste

The above method has the defects of serious waste of oil energy and electric energy, high investment, environmental pollution, corrosion of the runway and reduction of the service life of the runway
