Description

A kind of airport runway plasma glue removal equipment

technical field

The invention relates to the technical field of airport runway cleaning, in particular to an airport runway plasma degumming equipment.

Background technique

The rubber left on the runway of the aircraft taking off and landing has always been an important factor that threatens the safety of aircraft taking off and landing.

When aircraft tires touch the runway surface due to friction at high speed, the high temperature causes the rubber melt formed by the instant melting of tire rubber and adheres to the texture of the runway surface. The surface rubber layer continues to accumulate and thicken, and the accumulated rubber layer reduces the friction coefficient of the runway surface, which affects the braking performance of the aircraft. Especially when the road surface is wet and slippery, the viscosity of the rubber on the runway significantly reduces the friction force. affect the safe landing of the aircraft.

Make sure that the friction coefficient of the pavement surface is not less than 0.5, so as to avoid accidents. Therefore, the airport runway should be continuously cleaned of the pavement rubber.

At present, there are mainly the following three methods in use at the airport: shot blasting, high-pressure water washing, and chemical preparation.

The shot blasting method uses one or more turbines in the shot blasting equipment to spray iron microbeads to the treated surface. During the spraying, the softer parts of the surface are removed to form an extremely superficial irregular "orange peel" structure. The ejected microbeads and garbage are sucked by the vacuum cleaner connected to the shot blasting machine. After a special filtering system, the metal microbeads will be automatically separated from the garbage. After the metal microbeads are cleaned, they return to the microbead cycle, and the garbage is separated into the output box. The existing problems are: the metal microbeads are difficult to recover in rainy and snowy weather, and the residual metal microbeads are sucked into the engine, which will damage the engine and cause safety hazards.

The method of high-pressure water flushing is to use flexible flushing force and cleaning equipment. The penetrating force of its high-speed water flow can rapidly expand along the interface between the rubber or paint coating and the substrate, causing it to peel off quickly, but the high-pressure water also collides with the pavement surface. Over time, it will affect the service life of the runway and cause frequent maintenance. , the airport has a limited number of available runways, usually only one or two, which seriously affects the normal operation of the airport.

Chemical formulation methods generally utilize a mixture of terpenes, hydrocarbons and/or ethers, nonionic and/or anionic surfactants. Spray or manually pour the glue remover on the tire rubber of the airport runway or taxiway. After about 1 hour, the silt will peel off from the surface of the runway and fall off into fine particles after infiltration, swelling and loosening. Finally, rinse with water or artificially. Scrub clean. The problem is: under the increasingly stringent environmental protection requirements, chemical preparations must focus on the impact on the surrounding environment, so they will gradually withdraw from the historical stage.

The above three traditional degumming methods are unsafe, not environmentally friendly, and cause great damage to the pavement. Plasma glue removal also occurs in the prior art, but the existing plasma glue removal method consumes a lot of energy, the efficiency needs to be improved, and the road surface is damaged.

At present, there is a lack of a glue removal method with low energy consumption and high glue removal efficiency in the prior art.

As shown in FIG. 1, an airport runway plasma degumming equipment includes: a carrier vehicle body 1, a rolling electrode 12 installed at the bottom of the carrier vehicle body 1, and a discharge electrode assembly installed at the bottom of the carrier vehicle body; And the oxygen generator 4, the radio frequency power supply 5 and the control unit installed in the carrier body 1;

The ground electrode 12 is connected to the negative electrode of the radio frequency power supply, and is in rolling contact with the road surface rubber layer of the airport runway when it is used, and is used to temporarily polarize the road surface rubber layer of the airport runway to form the temporary discharge electrode of the discharge electrode assembly;

The discharge electrode assembly is directly coupled with the road surface rubber layer of the airport runway to discharge and stimulate the high-purity oxygen sprayed from the oxygen generator 4 to generate high-concentration plasma to vaporize the road surface rubber layer;

Oxygen generator 4 is used to produce high-purity oxygen with air as raw material;

The radio frequency power supply 5 is used to provide high voltage and high frequency power supply for the array electrode assembly 2;

The control unit is used to control the operation of the ground electrode 12 , the discharge electrode assembly, the oxygen generator 4 , the radio frequency power source 5 and the generator 3 .

It can be understood that, the airport runway plasma degumming equipment also includes a generator 3 for power supply.

The airport runway plasma degumming equipment provided by the present invention uses a direct-coupled discharge between the array electrode assembly and the road surface adhesive layer, and uses the road surface adhesive layer as a discharge electrode and at the same time as a degumming object; through the array electrode assembly and the road surface adhesive layer The high-concentration and high-purity oxygen plasma generated by the discharge between the rubber layers of the airport runway will burn and gasify the rubber layer at a low temperature, so as to completely remove the rubber layer of the road surface without damaging the road surface, and it has the ability of all-weather degumming.

The plasma of the invention is directly generated on the surface of the runway, which reduces the energy loss and the neutralization of the plasma during the ejection process of the plasma generator, reduces the loss of electric energy, and at the same time greatly reduces the discharge voltage and isothermal temperature, and reduces the impact on Temperature shock and damage to the runway surface; it can also greatly improve the removal efficiency.

In an embodiment of the present invention, the macroscopic temperature of the direct-coupled discharge depends on the distance between the array electrode assembly and the road surface adhesive layer, the voltage and frequency of the radio frequency power supply, the oxygen supply pressure of the oxygen generator, and the air flow velocity of the nozzle. and parameters such as the traveling speed of the glue removal equipment; compared with the traditional plasma glue removal technology that requires plasma to be generated in the plasma generator and sprayed on the road surface, the present invention combines the generation, spraying of the plasma and the effect of the glue layer. The processes are combined together to avoid the energy loss and the neutralization of the plasma in the process of plasma ejection in the traditional technology, so the macroscopic temperature of this technology can be reduced under the premise of achieving the same or even better degumming effect.

In a specific embodiment, the plasma is not generated in the ion generator or in the plasma torch, but is directly coupled with the track surface through the array electrode assembly, so that the plasma concentration can be increased by more than 1 times, per unit time The internal glue removal area is at least doubled compared to the traditional plasma glue removal equipment.

In a specific embodiment, there are two ground electrodes 12, which are respectively arranged on both sides of the array electrode assembly 2 at a distance of 5-10 cm from the edge of the discharge electrode assembly. It will greatly reduce the polarization effect of the road surface rubber layer. And the ground electrode 12 and the discharge electrode assembly are both arranged at the bottom of the vehicle body 1; the ground electrode 12 is connected to the negative electrode of the radio frequency power supply 5, and is used to temporarily polarize the road surface glue layer, so that the discharge electrode assembly is placed on the surface of the glue layer. Create conditions for discharge and generation of high-concentration plasma.

In a specific embodiment, the discharge electrode assembly is an array electrode assembly 2 .

As shown in FIG. 2 and FIG. 3 , the ground electrode 12 temporarily polarizes the track surface rubber layer 18 through the conductive rubber 21 , the array electrode assembly 2 is a platinum electrode 15 , the platinum electrode 15 is covered with an insulating layer 20 , and the platinum electrode 15 One end is connected with the positive pole of the radio frequency power supply 5 through the cable 23, and the other end is the tip 16 and is 15-40mm from the ground; each platinum electrode 15 is surrounded by a ventilation tube 22; the upper end of the ventilation tube 22 is provided with an oxygen input port 19, and the bottom is provided with an oxygen spray Exit 17. The oxygen generator 4 is connected to the oxygen input port 19 of the ventilation pipe 22 through a pipeline, and the oxygen is transported into the ventilation pipe 22 for generating plasma to remove the road surface rubber layer 18 .

In an embodiment of the present invention, the gas pressure of the high-purity oxygen supplied to the vent pipe 22 is 1×10 ⁵ Pa, and the flow rate is 12 m/s. Because the plasma is generated by discharge under atmospheric pressure, the gas pressure is 1× 10 ⁵ Pa, the high-purity oxygen flow rate in the pipeline is generally 12m/s under atmospheric pressure, and if it is too large or too small, the plasma generation efficiency will be low.

In an embodiment of the present invention, the array electrode assembly 2 includes 2-50 rows of platinum electrodes 15 with 2-50 electrodes in each row; the frequency of the radio frequency power supply 5 is 300KHz-30GHz, and the voltage range is 10-30kV. Too few or too sparse electrodes are not enough to form an electrode array assembly, and the glue removal range is too small, and the glue removal efficiency is too low; too much and too dense electrode arrangement will cause a certain amount of waste of resources, and will also cause the array electrode assembly to be too large. , can not be well received into the car body; considering that the radius of the needle tip body is 0.1mm, the distance between the needle tip bodies is 30mm, the width of the minivan is generally 1.9m, and the width of the entire equipment, the array electrode assembly is set to 2 -50 rows, 2-50 needle tip bodies in each row.

As shown in FIG. 4 , in an embodiment of the present invention, the airport runway plasma degumming equipment further includes a preprocessing unit 11 disposed at the bottom of the carrier body 1 and connected to the control unit in communication, including infrared detection sensors, humidity detection Sensors, water detection sensors and road processing units;

The infrared detection sensor is used to measure the temperature data of the airport runway in real time and transmit it to the control unit;

The humidity detection sensor is used to measure the humidity data of the airport runway in real time and transmit it to the control unit;

The water accumulation detection sensor is used to measure the water accumulation depth data of the airport runway in real time and transmit it to the control unit;

The control unit receives the temperature data, humidity data and the water depth data and compares it with the preset threshold data to determine whether the working conditions of the array electrode assembly are reached, if not, the road processing unit controls the The airport runway is processed; if reached, the operation of the array electrode assembly is controlled.

The efficiency of the road surface plasma degumming operation is closely related to the road surface condition. Too high or too low humidity is not conducive to the development of the degumming operation (for example, when there is water on the road surface, the traditional plasma degumming operation cannot be carried out). Temperature also directly affects the degumming effect. The preprocessing unit has built-in infrared detection, water and humidity detection sensors, and sends the temperature, water depth and humidity information of the road surface to the control unit. Operating conditions of the electrode assembly. If it is not reached, the road treatment unit will treat the airport runway. For example, if there is accumulated water on the road surface, the accumulated water will be discharged to the surrounding area by cold blowing; if the road surface is too dry and cold, the road surface will be treated with hot steam. , to keep the best temperature and humidity closed environment in the dust hood, in order to obtain the best pavement treatment condition with temperature at 10℃～50℃, humidity at 20%～50%, and no other dust and impurities. When the control unit determines that the working conditions of the array electrode assembly are reached, the array electrode assembly is controlled to work. The road treatment unit may include hardware for performing hot steam treatment and cold blowing treatment on the road surface according to specific requirements, and the present invention does not limit the specific hardware.

The pretreatment unit 11 adjusts the humidity of the adhesive layer on the road surface to create optimal conditions for the discharge of the array electrode assembly (temperature 10°C to 50°C; humidity 20% to 50%), which can improve the plasma adhesive removal efficiency. Without this component, in bad weather conditions such as rainy and snowy weather, the array electrode assembly has poor discharge conditions and low glue removal efficiency, so that the equipment cannot achieve the desired glue removal effect or even work. For example, when there is stagnant water on the road surface, the traditional plasma glue removal operation cannot be carried out. The existence of this component makes the equipment not affected by rain and snow weather and has all-weather degumming ability.

Identify road conditions.

The image acquisition unit 24 is used to acquire the road surface image of the airport runway and transmit it to the control unit;

The control unit receives the echo data and the pavement image, and identifies the adhesive range, thickness, pavement joints and lamps of the airport runway of the pavement adhesive layer according to the echo data and the pavement image.

The identification unit 10 automatically identifies the range, thickness, road surface joints and runway lamps of the glue accumulation, and feeds back the information to the control unit.
