Description
Technical Field
The invention belongs to the technical field of cleaning machines, and particularly relates to a liquid carbon dioxide cleaning machine and a cleaning method.
Background
Since the 21 st century, the tunnel engineering construction in China enters a vigorous development period, and the total mileage of tunnels is continuously increased in the years. With the continuous maturity of construction technology, more and more highway tunnels are built in China. Although the construction technology of the highway tunnel in China is continuously developed and broken through, the problem of cleaning the highway tunnel is not valued by tunnel builders and people for a long time. The tunnel, especially the long road tunnel, is seriously polluted in the long-term operation process. The exhaust gas emitted from automobiles includes a large amount of solid suspended particulate matters, carbon monoxide, carbon dioxide, nitrogen oxides, sulfur oxides and the like. Fuel oil stains and flying dust are also main pollution sources. These contaminants diffuse away within the tunnel and attach to the interior walls of the tunnel lining, electromechanical equipment (ventilation, lighting, etc.), and the upholstery of the tunnel. These dirt often cannot be cleaned in time, so that lighting equipment and traffic lights in the tunnel become dim, the aging speed of electromechanical equipment is accelerated, and the air quality is deteriorated. When the pollution is serious, the driving sight and the body health of a driver are influenced, even symptoms such as dizziness and the like appear, the phenomena can influence the normal operation of the tunnel, and equipment failure and even traffic accidents occur.
At present, clear water is mostly adopted in China to clean tunnels, the method for cleaning the tunnels not only consumes great amount of water resources and is not environment-friendly, but also causes certain damage to electromechanical equipment in the tunnels by water containing impurities.
There is currently a method of cleaning tunnels with dry ice: the working vehicle stores liquid carbon dioxide and conveys the liquid carbon dioxide to a working area, the carbon dioxide in a solid-gas mixed state is sprayed to dirt on the surface of the lining through a series of devices, solid dry ice particles penetrate into gaps of the dirt, the temperature of the dry ice particles is extremely low, the dirt can be frozen, micro explosion occurs in the gaps of the dirt, and the volume of the dry ice particles is expanded by hundreds of times, so that the dirt is cracked and peeled off. Compared with the method for cleaning the tunnel by using clear water, the method can effectively clean the dirt on the surface of the tunnel lining, saves water resources, is very environment-friendly, and avoids the damage of water to electromechanical equipment. However, the raw materials of the cleaning method are wasted to a certain extent in the using process, because in the process that liquid carbon dioxide is converted into solid carbon dioxide (dry ice) and sprayed to the tunnel lining, part of the raw material liquid carbon dioxide is converted into gaseous carbon dioxide and sprayed to the surface of concrete, and the gaseous carbon dioxide is ineffective to clean the lining. In addition, the cleaning method has certain damage to the lining concrete.
