DE19549269A1 - Ecological carwash system for cleaning exterior and undercarriage of commercial road and rail vehicles - Google Patents

Abstract

In the carwash system water is recirculated, using rain water and the fresh water consumption is not more than fifteen percent. The drain water is insignificant as excess water is filtered and ozonised. The heating of the washing water is achieved by regenerative and environmental friendly technology, reducing by forty per cent the necessary detergent quantity, and using solar technology and block-type heat generation technology. Heating of the wash-hall is achieved through application of passive and active solar architecture, through which seventy percent of the necessary heating energy is gained by transparent thermal insulation or air collectors. The mobility installation is aligned to the respective vehicle type, having high-pressure water nozzles in a mobile three-brush, portal carwash and in a device for the undercarriage washing.

Description

State of the art

It is known to operate car washes through manual effort, high energy, water and chemical consumption of food are marked.

It is also known that there are car washes with other devices and sub-processes improvements and quality improvements in the washing pro want to achieve zessen. But the driving is not throughput per hour and the washing quality achieved simultaneous effort savings, which at Cleaning vehicles with different con structures is achievable.

problem

The claim is based on the problem that mechanized cleaning (uppercarriage, chassis and Engine washing) of road vehicles and rail vehicles do not testify in every approved size and construction on using heated washing water by means of brisk Renewable energy can take place and despite circulation of the wash water the water quality is maintained.

solution

This problem is solved by the claim led characteristics solved.

Achieved advantages

The advantages achieved with the invention are in particular to achieve in particular:

• - a high quality of washing processes with simultaneous Minimize the use of chemicals
• - Water savings of up to 90% of those otherwise required amounts
• - low use of fossil fuels
• - no waste water
• - a vehicle throughput of 4-5 vehicles per hour de
• - minimized hazardous waste.

description of drawings

In the drawings, the invention is shown and will be described in more detail below.

Show it:

Fig. 1, the washing and function hall, which enables through its So lararchitektur energy savings,

Fig. 2 shows the overall structure of the indoor and outdoor facilities as an ecological and traffic-sample solution,

Fig. 3, 4, 5 which meet the energy needs for domestic hot water and heating to predetermined seasons,

Fig. 6 shows the arrangement of the devices for the func kidney of the washer,

Fig. 8 shows the energy system as a complete system.

The building has a flat sloping roof for solar energy use and the Kubator is compact. The heat losses are relatively small. The east-west orientation results in an elongated south facade, which enables inexpensive solar radiation and, through the use of appropriate materials, enables the supply of glare-free light. ( Fig. 1 and 2).

The washing water is heated and the electricity generated, as well as the heating in the hall, by a solar system that generates around 30% of the thermal energy in winter and around 80% in summer. The additional energy required is produced by a combined heat and power plant and in extreme winter months with an additional gas boiler. ( Fig. 3, 4, 5, 7) The heated water enters the water circuit via a buffer tank ( Fig. 8).

The washing technology consists of a portal washing system with or without rotating 4-point high pressure jet nozzles. Such high pressure jet nozzles are also used for driving rack cleaning. The one led through the buffer storage Wash water is circulated. That is achieved condition in addition to the use of sludge trap, Ben tin separator, coalescence separator and the sample removal chute through an automatic backwash filter and an ozone generator.

Claims (1)

Process and device for mechanical exterior cleaning, including mechanical underbody cleaning of commercial vehicles and rail vehicles, characterized in that the vehicle treatment is carried out by simultaneously fulfilling the following six conditions:

• a) the circulation of the water using rainwater, in which the usability of the water is retained, the fresh water consumption is not higher than 15% and wastewater is only slightly present as excess water and is achieved by filtration and ozonization,
• b) the heating of the washing water with regenerative and environmentally friendly energy technology, in which the use of detergent is reduced to at least 40% of the otherwise necessary amount and is achieved by using solar technology and / or combined heat and power plant technology,
• c) the heating of the washing hall by using the passive solar architecture; through which 70% of the required heating energy is obtained and is achieved through the use of transparent thermal insulation or air collectors,
• d) the arrangement of movable high-pressure wash nozzles to be aligned to the respective vehicle type in a movable three-brush gantry wash system and in a device for washing underbody,
• e) the use of a device which, through its design and arrangement, is capable of generating active and passive solar energy and of being able to treat vehicles of all kinds.
• f) the use of a device for engine washing, parts cleaning and dewaxing, which guarantees freedom from waste water through physical separation and reuse of the water.
