It relates to a solid-liquid mixed waste supply device.

In general, combustible wastes generated at various industrial sites are treated in such a way that they are mainly landfilled or incinerated.

However, the landfill method causes a problem of contaminating soil and groundwater, and the incineration method emits dioxins and induces secondary pollutants, such as generating ashes containing heavy metals during incineration.

Therefore, a gasification melting method for gasifying and treating combustible wastes has been used as an alternative.

Gasification melting method is a method of thermally decomposing waste in an oxygen-free atmosphere to obtain unburned carbon powder and carbonized gas as a heat source, and the remaining ash is melted to be treated in slag form.

In the gasification melting method, there is a method of supplying and treating mixed waste mixed with solid waste and liquid waste in order to improve the efficiency of waste supply and gasification efficiency. According to this method, the solid waste and liquid waste can be treated in combination. There is an advantage.

Here, the solid wastes include fly ash and floor ash generated from incineration power generation facilities, industrial waste dregs, dry sludge produced by dry grinding of sludge produced in sewage treatment plants, and generally have a particle shape of about 500 μm.

Meanwhile, liquid wastes include waste oil, waste lubricating oil, waste compressed oil, waste solvent and the like.

The operation of the solid-liquid mixed waste supply apparatus according to the present invention having the above configuration will be described below.

First, the manned blower 20 is driven so that the solid waste 1 in the form of powder particles is sucked through the charging pipe 12 to be charged into the solid waste storage tank 14, and the solid waste storage tank together with the solid waste 1. The air sucked into 14 is discharged to the atmosphere through the exhaust pipe 18.

At this time, the solid waste 1 is prevented from flowing into the exhaust pipe 18 together with the air by the filter 16 installed at the tip of the exhaust pipe 18.

Subsequently, the supply blade 24 in the solid waste storage tank 14 is rotated by the driving of the supply blade motor 22, and the solid waste supply opening / closing valve 26 provided at the lower side of the solid waste storage tank 14 is opened. Then, the solid waste 1 in the solid waste storage tank 14 is smoothly transferred to the lower side by the supply blade 24 is rotated is discharged through the solid waste supply opening and closing valve 26, the discharged solid waste (1) Through the solid waste supply pipe 28 is supplied to the mixer device 40.

On the other hand, the liquid waste stored in the liquid waste storage tank 30 is supplied to the mixing device unit 40 through the liquid waste supply pipe 34 by the driving of the liquid waste supply pump 32.

The solid waste 1 supplied to the mixing device part 40 is supplied to the upper tube 41 of the mixing device part 40, and then is supplied by the supply screw 44 which is rotated by the driving of the supply screw motor 43. After being smoothly transferred downward through the discharge opening 42 of the upper pipe 41, it is uniformly distributed and discharged in all directions by the supply distribution plate 45 mounted at the tip of the supply screw 44.

On the other hand, the liquid waste to be supplied to the mixing unit 40 is sprayed at the same time from the liquid waste supply nozzle 47 which is provided in the circumferential direction on the upper side of the lower pipe 46 of the mixing unit 40 at the same time The solid waste (1) distributed and discharged from the supply distribution plate 45 is primarily rapidly mixed.

Subsequently, the mixed waste stored in the mixed storage tank 50 is secondarily mixed by the stirring blade 54 which is rotated by the driving of the stirring motor 52, and the mixed waste having the mixing completed is the lower side of the mixed storage tank 50. With the opening of the mixed waste supply opening / closing valve 58, the quantitative supply pump 60 is driven through the mixed waste supply pipe 62 and quantitatively supplied to the gasification apparatus.

At this time, since the pressure is present in the mixed waste supply pipe 62 at the rear end of the fixed-quantity supply pump 60, the solid waste (1) particles in the mixed waste being transported are solid-liquid separated and deposited in the mixed waste supply pipe 62, thereby causing the mixed waste supply pipe. Since the 62 can be closed, the anti-clogging motor 72 of the anti-clogging device 70 is driven so that the anti-clogging rotating body 76 is rotated in the mixed waste supply pipe 62, thereby from the mixed waste to be conveyed. The solid waste 1 is separated and prevented from being deposited.

In this way, the mixed waste is discharged from the mixed storage tank 50 is continuously supplied to the gasification melting apparatus side, at which point the weight of the mixed waste in the mixed storage tank 50 is lowered below the preset value in the controller 80 If it is measured by the weighing sensor 56, the controller 80 controls the mixed waste to be stored again in the mixed reservoir (50).

In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

According to the present invention, a stable continuous supply of the mixed waste is automatically enabled, so that the effect of improving complete gasification and improving the gasification efficiency of the gasification melting process can be achieved.
