The sewage treatment device 12 is used for simply filtering, separating oil, precipitating and the like on sewage generated in the previous car washing process, and treated reclaimed water is injected into a water storage tank, is pumped by a centrifugal pump, and is conveyed and supplied to a reclaimed water spray head 34 and a chassis cleaning spray head 36 through a water pipe.

The corresponding procedures are as follows:

1) the vehicle to be cleaned is driven forward into the vehicle cleaning area. In the process of entering the automobile, executing the step a, measuring a tire position signal in the control module 11, and enabling the hub cleaning nozzle 30 to be aligned with the hub to spray a hub cleaning agent, so that the severe dirt on the hub has enough time to be dissolved; and b, according to the measured head position signal, the prewashing spray head 31 is aligned to the middle lower part of the automobile to spray the silt loosening agent, so that the thicker silt at the lower part of the automobile body becomes soft, and the absorption and reaction of the cleaning agent sprayed in the subsequent step b are facilitated.

Simultaneously, step k is performed for the moving car: the fog-like reclaimed water is sprayed to the chassis of the vehicle body, so that the chassis and parts above the chassis are properly cooled, and the risk of vehicle damage caused by temperature sharp drop caused by subsequent chassis water flushing and cleaning is reduced.

2) And c, after the automobile is stopped stably in the automobile cleaning area, executing the step b, spraying a glass cleaning agent to the windshield of the automobile body, and spraying a front face cleaning agent to the automobile head by a cleaning nozzle for cleaning the front part of the automobile. In addition, the moving frame 13 travels over the parked car while the cleaning spray head 32 sprays the cleaning agent to the entire car body.

The hub cleaning agent, the silt loosening agent, the glass cleaning agent and the cleaning agent sprayed in the steps a and b are subjected to heating treatment to accelerate the processes of permeation, absorption, emulsification and the like, so that the chemical agents react more fully, and waste and unnecessary consumption are reduced.

3) The infrared measuring device of the control module 11 measures the body contour data of the vehicle to be washed to obtain the height of each part of the body, the side position of the body and other data. Therefore, in the subsequent step two and the step three, the high-temperature water vapor spray nozzle 33, the reclaimed water spray nozzle 34 and the clear water spray nozzle 35 can keep proper distances from the outer surface of the vehicle body as required, and a good liquid spraying effect is realized.

4) And (5) executing the step two: the high temperature steam is sprayed to the vehicle body by the high temperature steam spray head 33. The high temperature water vapor can reach over 150 deg.c and may be used as effective heat source. The high-temperature water vapor is generally a gas-liquid mixture, the liquid drops of the high-temperature water vapor are in a fine-particle fog shape, the heat transfer effect is good, the temperature of the surface of the automobile can be quickly raised, and the concentration of the automobile washing liquid covered on the automobile body cannot be greatly diluted. Meanwhile, the problems of high turbidity of the active agent, high specific energy consumption and the like which are faced by directly heating the car washing liquid to the high temperature of more than 50 ℃ are solved. Generally, the data measured in the previous step is relied on in this step, and the control module 11 ensures that the high-temperature water vapor spray nozzle 33 is kept as close as possible to the vehicle body, so as to reduce heat loss and improve the operation effect.

5) And step l is executed: the vehicle body is washed with the reclaimed water supplied from the sewage treatment device 12. The function of the device is that the vehicle can be washed by the large-flow reuse water, so that the use amount of the subsequent clear water is greatly reduced. Secondly, if large-flow and low-pressure water is adopted in the step, most of gravel hard dirt on the vehicle body can be removed, so that the subsequent clear water washing is suitable for adopting higher washing force, and the problem of vehicle paint scraping caused by the fact that the hard dirt slides on the surface of the vehicle body along with high-speed water flow can not be caused.

While the vehicle body is being flushed at step l, performing step m: water is sprayed to the chassis of the vehicle body to wash dirt such as mud, dust and the like attached to the bottom of the vehicle. The reclaimed water obtained after the sewage recycling treatment is also used in the process.

6) And step three, washing the whole vehicle with clean water. The water pressure in this step is related to step l. And if the design goal of the step I is to completely remove the dirt of the vehicle body, the step III is mainly a rinsing function, and low-pressure water is used for removing the residual reclaimed water stain of the vehicle body. If the step I only removes the granular dirt on the surface of the vehicle body, the step I uses high-pressure water for washing, and the dirt is damaged, peeled and washed away by the impact force of the step I, so that a more thorough decontamination effect is realized.

After the above steps are finished, the decontamination work in the cleaning stage is finished.

And according to the automobile maintenance requirement, next executing the step c: the wax water is sprayed to the vehicle body by the wax water spray head 37, so that the paint of the vehicle body is protected, the surface brightness is improved, and the antistatic and antifouling effects of the vehicle body are enhanced. Then, the vehicle body is wiped, the deflector rod 5 of the water removing part drives the wiping cloth 93 to swing back and forth, and the sleeve 914 reciprocates to drive the wiping cloth 93 to swing left and right, so that the wiping and water removing of the vehicle body are realized.

Finally, the driver drives the vehicle away from the water removing area, and residual water on the surface of the lower part of the vehicle body and in gaps can be further removed in an air drying mode by the floor type fan 8 in the driving away process.

Therefore, the whole car washing operation flow including washing and water removal is completed.

2) through reasonable nozzle type selection, fluid parameter selection and pipeline switching design, different sprayers such as a high-temperature water vapor sprayer 33, a reclaimed water sprayer 34 and a clear water sprayer 35 can be shared, so that the arrangement mode of the sprayers is simplified;

3) the high temperature steam generator 331 may be based on various principles and structures, and the high temperature steam sprayed by the high temperature steam generator may be mist water droplets, or a gas-liquid mixture of the mist water droplets and the high temperature steam, such as: it can be mist-like liquid drops of hot water with the temperature below 100 ℃, or can be a mixture of water vapor and hot water with the temperature far exceeding 100 ℃;

4) the invention can be used on a non-contact car washer with a suspended machine body, and can also be widely applied to other types of car washers such as a floor type gantry car washer and the like;

5) the cleaning process can be used for cleaning automobiles, high-speed rail carriages and other vehicles.

Compared with the conventional cleaning steps: 1) the invention does not wet the car body with water at first, but directly sprays the car washing liquid, ensures the concentration of the car washing liquid and the absorption capacity of dirt gaps to the car washing liquid, strengthens the absorption and reaction capacities of the car washing liquid, and ensures the dissolving time; 2) the sequential arrangement of all the processes is beneficial to the full absorption of the car washing liquid and the heating treatment of the car washing liquid. The chemical reaction speed of the car washing liquid is normally positively correlated with the temperature, so the decontamination effect of the car washing liquid is further improved; 3) after the surface sprayed with the car washing liquid is heated by adopting high-temperature water vapor as a heat source, the decontamination effect of the car washing liquid is improved again; 4) the chassis is cleaned by a step-by-step treatment method, wetting is carried out first, and then washing is carried out, so that thermal shock of cleaning operation is greatly reduced, and vehicles are protected to the maximum extent; 5) the chassis and the vehicle body are timely cleaned by the reclaimed water, so that the treatment requirement of the corresponding reclaimed water is greatly reduced, the process requirement on a water circulation system is greatly reduced, and the consumption of the reclaimed water is reduced. Therefore, the invention is based on the engineering practice of vehicle surface cleaning, adopts reasonable steps, makes the chemical reaction of the vehicle washing liquid more sufficient, and reasonably utilizes the reclaimed water, thereby not only improving the vehicle cleaning effect, but also effectively reducing the consumption and the discharge of the vehicle washing liquid, greatly saving the use amount of the clear water, achieving the multiple purposes of synergy, environmental protection and water saving, and being convenient for realizing the whole-process automation.
