ABSTRACT:
TECHNICAL FIELD
The present invention relates to a waste water treating device, and more particularly, to a waste water treating device which can treat waste water containing waste printing ink which is generated from a printing factory, or waste water containing a variety of oil such as lubricating oil which is generated from a general factory.
BACKGROUND ART
Generally, in a printing factory all kinds of printing products are manufactured by using water or oil ink, and therefore waste water containing waste ink is generated. Further, even lubricating oil may be contained in the waste water due to activation of printing machines.
Meanwhile, the generation of the waste water containing the oil is not excluded in a general factory which machines is worked.
To prevent pollution of environment due to discharge of waste water out of factory, there is provided a conventional device which filters or purifies waste ink or oil contained in the waste water by using a filtering method by means of a filter, a sewage purification method, or a sedimenting method with medicines.
However, in the conventional device using the filtering method with the filter, if the filter through which a variety of sludge such as a waste ink particles, oil particles and so on is filtered is waste without any treatment, the filtered waste water is restored to its original waste water in the case where water is admixed to the wasted filter. Therefore, there is an inconvenience in that the completely used filter should be destroyed by fire.
Also, in the conventional device using the sedimenting method with medicines there are problems in that a purification cost is increased due to expensive medicine usage and a sediment should be re-treated. Additionally, if the treated water with the medicines is directly discharged, there occurs a problem in that river contamination is naturally accompanied since the treated water is short of the biological oxygen demand (BOD).
Due to an illegal exhaust of factory waste water, the waste water flows to general sewage or rivers to deteriorate soil or the water quality, which results in a serious destruction of natural environment.
DISCLOSURE OF INVENTION
An object of the present invention is to provide a waste water treating device which can completely prevent generation of contamination of natural environment caused due to factory waste water in order to be free from the above-mentioned problems.
Another object of the present invention is to provide a waste water treating device which can be installed in a small area and reduce installation and maintenance cost thereof.
To achieve these and other objects according to the present invention, there is provided a waste water treating device including: a treater which destroys by fire sludge such as waste printing ink, waste oil and the like contained in waste water and evaporates the waste water; a supplier which delivers the waste water from a collecting tank to the treater; and an ejector which ejects the waste water supplied from the supplier to a combustion chamber within the treater. With the waste water treating device according to the present invention, since the sludge such as waste printing water or oil ink, lubricating oil, cutting oil and so on can be completely removed in the destruction by fire manner and the waste water is evaporated, a re-treatment process is separately not required and further a large installation area is not occupied.
Further, a waste water treating device according to the present invention includes a separator which electrically separates the sludge such as ink particles or oil particles contained in the waste water and a preheater which preheats the waste water before it is delivered to the treater.
If the waste water is supplied and ejected in the combustion chamber within the treater by the operation of the supplier and the ejector, the waste printing ink or waste oil contained in the waste water is destroyed by the frames of a burner which is mounted within the combustion chamber and the waste water is then evaporated. During the process, if the waste water is passed through the separator, the various kinds of sludge such as printing ink particles, waste oil particles and the like contained within the waste water is electrically separated from the waste water and directly puts in the combustion chamber. Next, since a low density of waste water from which the various kinds of sludge is filtered is delivered to the preheater and is then preheated to be ejected within the combustion chamber, the printing ink particles or the waste oil particles are immediately destroyed by fire and the water is rapidly evaporated, which results in a complete removal of the generation of environment contamination due to the factory waste water.
