リングを容易とした技術である。In the above-mentioned Japanese Patent Laid-Open No. 49-98070, the waste melt is subjected to water granulation treatment, continuously carried out of the system by a belt conveyor, and the red hot non-magnetic melt and magnetic melt are handled. It is a technology that improves the environment, at the same time shortens the processing time, and reduces the processing space. In addition, Japanese Patent Publication No. 59-25143 discloses that non-magnetic melt and magnetic melt can be obtained by receiving granulated slag granulated with pressurized water having an appropriate amount of water and pressure in a cage in which water can flow freely inside and outside a water tank. It is a technology that enables safe water granulation of the mixed melt and facilitates handling.

る。The non-magnetic melt sorted by the magnetic separator is useful as a fine aggregate for concrete blocks, a fine aggregate for asphalt mixture, etc., and there is a problem of waste landfill shortage. Nowadays, there is a longing to promote effective use. When used as an aggregate, it is necessary to maintain the conventional quality and appearance.

浄効果も期待できることが判った。BEST MODE FOR CARRYING OUT THE INVENTION The use of a wet magnetic separator ensures the separation of a magnetic melt and a non-magnetic melt,
Moreover, since it is a wet type, magnetic water is stored in the non-magnetic melt pit, and it was found that a cleaning effect can be expected by passing the pit water by the non-magnetic substance.

必要であるため、大容量の排水処理装置を必要とする。To clean the non-magnetic melt, one of the methods is to keep the water granulated pit water and the non-magnetic melt pit water clean. In the case of diluting the water granulation pit or the non-magnetic melt pit by increasing the makeup water, a large amount of water is required, and thus a large capacity waste water treatment device is required.

た。However, if the non-magnetic melt rises above the water surface of the non-magnetic melt pit by the non-magnetic melt scraping conveyor, clean cleaning water can be directly sprayed onto the non-magnetic melt to wash it with a small amount of water. It turned out that the effect was significantly improved.

Clean water is sprayed through the granulation pit and the non-magnetic melt pit in this order, and is gradually cleaned by contacting with clean water gradually.

ことが可能となる。Further, since the amount of spray water is smaller than that for cooling the combustion furnace exhaust gas, it is possible to use part of the clean water conventionally used for gas cooling as spray water. Alternatively, by using the overflow water of the non-magnetic melt pit as a part of the gas cooling water, the non-magnetic melt can be washed without increasing the amount of water used as compared with the conventional case.

洗浄が可能となる。Further, a very small amount of foreign matter such as sludge contained in the overflow water is sprayed on the gas cooling tower in a state of being mixed with the overflow water, and is collected together with the dust by the dust collector located in the downstream thereof. Non-magnetic melt cleaning is possible without the need for a treatment device for sludge in overflow water.

下する。EXAMPLE An example of the present invention in a municipal solid waste melting furnace using coke as a heating and melting heat source will be described below with reference to the drawings. The magnetic melt a and the nonmagnetic melt b generated from the melting furnace 1 exist as a mixture in the water granulation pit 2. This mixture is scraped up onto the water surface by the mixture scraping conveyor 3, passes through the mixture chute 4 installed on the water surface in the downward direction, and falls onto the slag supply feeder 5.

The magnetic melt a adheres to the magnetic selection drum 6 by magnetic force, is scraped off by the magnetic material scraping plate 7 while rotating together with the magnetic selection drum 6, falls, and slides down in the magnetic melt chute 8 by its own weight, resulting in magnetic melting. It is stored in the product hopper 9. The structure of the magnetic separation drum 6 shown and the method of supplying the magnetic separation drum 6 to the drum are merely examples, and other known materials may be used.

After being carried out, it is washed with water sprayed from the slag cleaning water spray device 12.

Becomes smaller and draining becomes insufficient. Therefore, it is appropriate that the position of the water spray device 12 for slag cleaning is about 100 to 200 mm above the water surface and rises along the conveyor 13 for scraping the non-magnetic melt.
The non-magnetic melt b falls in the non-magnetic melt chute 14 and is stored in the non-magnetic melt hopper 15.

By spraying clear water, sludge and the like are reduced, a clean slag that does not impair the quality of the product is obtained, and the use of slag as an aggregate is greatly promoted.
