Spill clean-up system and method
A mobile cleaning system to be used for cleaning organic liquids from a hard surface includes tanks for storing water, and for storing used, dirty water after cleanup. A water-based cleaner is sprayed onto the spill, which can be, but need not be, done in connection with the cleanup system. A high throughput vacuum system removes the hot water and the spill materials concurrently as the hot water is applied to the treated area. The vacuumed liquids are stored in an on-board tank for later disposal.
1. A mobile system for using water to clean an organic spill from a contaminated hard surface, the mobile system comprising:
a mobile platform operably mounted on wheels for movement across the contaminated hard surface, the mobile platform having a width;
at least one clean water storage tank mounted on the mobile platform for storing the water;
a cleaning hood operably mounted on the mobile platform such that the cleaning hood may be positioned immediately above the contaminated hard surface, the cleaning hood extending across substantially the entire width of the mobile platform;
at least one heater compressor unit for heating water from the at least one clean water storage tank, compressing the water to at least 3,500 psi, and spraying the water through nozzles positioned within the cleaning hood, so that the water is directed onto the contaminated hard surface under the cleaning hood;
a waste water storage tank mounted on the mobile platform, and isolated from the at least one clean water storage tank, so that no water from the waste water storage tank contaminates the water in the at least one clean water storage tank;
a vacuum generator for generating a vacuum in the waste water storage tank;
wastewater lines extending between the waste water storage tank and the cleaning hood, so that contaminated water from the contaminated hard surface is drawn into the waste water storage tank, and
an extension hingedly coupled to the mobile platform;
wherein the waste water storage tank is held in a constant state of negative pressure to prevent spillage.
2. The mobile system according to claim 1 , wherein the at least one heater compressor unit heats the water to just below the boiling point of water.
3. The mobile system according to claim 1 , the extension comprising:
an extended cleaning hood operably mounted on the extension, the extended cleaning hood extending across substantially the entire width of the extension;
nozzles positioned within the extended cleaning hood, so that the water is directed onto the contaminated hard surface under the extended cleaning hood; and
extended wastewater lines extending between the waste water storage tank and the extended cleaning hood, so that contaminated water from the contaminated hard surface is drawn into the waste water storage tank.
4. The mobile system according to claim 3 , the further comprising:
an actuator coupled between the mobile platform and the extension for allowing the extension to rotate relative to the mobile platform.
5. The mobile system according to claim 1 , further comprising:
an attachment for small area cleaning having;
a nozzle in fluid connection with the least one heater compressor unit; and
a vacuum hood for containing a spray of fluid from the nozzle;
wherein the vacuum hood is in fluid connection with the waste water storage tank.
6. The mobile system according to claim 5 , wherein the vacuum hood includes a plurality of channels.
