Vehicle cleaning system
First Claim
1. A high-pressure brushless system for cleaning large vehicles on a vehicle path as the vehicles pass through a pre-wet station, a wash station and a rinse station, with the wash station and the rinse station capable of directing sprays of washing liquid and rinsing liquid onto vehicles of specific outer configurations at a specific impact angle and a specific impact pressure to achieve optimum cleaning of vehicles of various outer configurations, said system comprising a source of pre-wetting liquid;
- a pre-wet conduit arch at the pre-wet station and connected to the source of pre-wetting liquid and having an arrangement of nozzles designed to direct sprays of pre-wetting liquid onto a vehicle moving on the vehicle path through the pre-wet station to adjust the vehicle body temperature;
a source of washing liquid;
a plurality of wash conduit arches at the wash station, each of the wash conduit arches connected to the source of washing liquid and having a particular arrangement of nozzles designed to direct sprays of washing liquid onto a vehicle moving on the vehicle path through the wash station, with each arch and the nozzles thereof of the wash conduit arches designed to provide a specific impact angle and a specific impact pressure of washing liquid on the surface of a vehicle having a specific outer configuration and moving on the vehicle path through the wash station;
a source of rinsing liquid;
a plurality of rinse conduit arches at the rinse station, each of the rinse conduit arches connected to the source of rinsing liquid and having a particular arrangement of nozzles designed to direct sprays of rinsing liquid onto a vehicle moving on the vehicle path through the rinse station, with each arch and the nozzles thereof of the rinse conduit arches designed to provide a specific impact angle and a specific impact pressure of rinsing liquid on the surface of a vehicle having a specific outer configuration and moving on the vehicle path through the rinse station; and
control means for selectively activating a mated set of one wash arch, for spraying washing liquid therefrom, and one rinse arch, for spraying rinsing liquid therefrom.

Abstract
A system for cleaning vehicles, such as train cars, locomotives, buses, and large trucks, of various outer configurations, with optimum cleaning of each vehicle regardless of outer configuration and without use of brushes. The apparatus includes a prewet station, a wash station and a rinse station. The wash station has several conduit arches, each with an engineered nozzle arrangement that provides a specific impact angle in the order of about 80 degrees and a specific impact pressure in the order of from about 0.3 to about 0.5 psi of the washing liquid on vehicles of a specific configuration. The rinse station likewise has several conduit arches, each with an engineered nozzle arrangement that provides a specific impact angle in the order of about 80 degrees and a specific impact pressure in the order of from about 1.5 to about 2.0 psi of the rinse liquid on vehicles of a specific configuration. Each arch is shaped and sized to allow passage of the largest vehicle to be cleaned. The nozzle placement and design vary from arch to arch at the wash station and at the rinse station, and each arch provides a specific liquid spray pattern, including a specific impact angle and a specific impact pressure on vehicles of a particular associated configuration. At the prewet station each vehicle is sprayed by a prewet liquid which serves primarily to being the vehicle surface to the desired temperature, and so a single conduit arch with nozzles designed for a general overall spray pattern is provided at the prewet station. The liquid runoffs from the prewet station, the wash station, and the rinse station are collected and recycled separately. An operator determines the configuration of each vehicle entering the apparatus and activates the appropriate associated wash and rinse conduit arches. The equipment is housed within a building which can have air curtains at the building entrance and exit.
