The present invention extracts fuel oil from gas and steam produced by thermal decomposition of waste tire fragments by dry distillation furnace, and heat which separates recyclable by-products such as carbon and metal from other by-products by wet method, not dry method. The present invention relates to a sediment cooler for a recycled by-product underwater separator of decomposed waste tires.

In general, waste tires are composed of at least 50% of a polymer compound, about 30% carbon, about 20% iron core or fiber, and inorganic additives.

If such waste tires are disposed of as they are, there is a serious problem that sulfur contained in the rubber of the waste tires not only pollutes the ecosystem such as soil, but also incurs a great amount of toxic gas and soot when it is incinerated. there was.

Thus, the waste tires were pulverized into small pieces and thermally decomposed by a dry distillation furnace, but the fuel oil was extracted and recycled byproducts such as carbon and metal were recovered.

As such, a device for separating fuel oil and carbon, metal, etc. from waste tires has been known in a number of forms, which will be described below with reference to Korean Patent Publication No. 2004-110292.

This is supplied to the crushed waste tire through one side hopper of the distillation furnace, the distillation furnace is thermally decomposed as the waste tire fragment is moved into the distillation by the screw provided therein while rotating in the linkage drive by the drive motor It goes through the process.

That is, the waste tire fragments are thermally decomposed by the high heat radiated from the external heating device of the dry distillation furnace and the high temperature saturated steam (about 500 ° C.) injected by the steam generator into the dry distillation furnace, thereby decomposing the gas, steam and the By-products such as carbon and metal are emitted.

The gas and steam condense through cooling by a cooler and a storage tank, thereby extracting fuel oil. At this time, the surplus gas and steam may be reused as a fuel for driving a heating device in a dry flow furnace.

In addition, the by-products, such as carbon and metal, are discharged through the outlet of one side by dry distillation and moved by the conveyor to separate and recycle carbon and metal by a separate separation device.

In other words, the carbon and metal by-products are first separated from the metal, and the carbon and the metal are separated and extracted separately by a separate separation device, and the other sludge is disposed of.

By the way, the conventional apparatus described above has a problem that the explosion risk is involved.

That is, by-products such as carbon and metal discharged from the drying furnace are actually supplied at a high temperature, and gas is supplied, so that there is a risk of explosion due to the friction spark during the process of drop transporting them to the metal conveyor.

Therefore, the present applicant has been devoted to research and development in order to improve the above-mentioned problems, and according to the Republic of Korea Patent Application No. 2005-396121, the by-products such as carbon, metal, etc. discharged from the dry distillation furnace in the outside air is blocked, even in the water Since carbon and metal are separated, the problem of explosion and air pollution due to harmful gases was solved.

However, in the process of implementation, a new problem arises in the applicant's prior application technology, which is due to the carbon and metal continuously injected into the high temperature state in the dry-flow furnace when the carbon and metal are separated in water. As the temperature rose rapidly, harmful gases and vapors were leaked to the outside, resulting in severe odors and fatal safety problems.

The present invention was devised to fundamentally solve the problems newly generated in the above-described application by the present applicant, and recirculated to the cooling state by draining the sediment water in the tank tank into which the by-products such as high temperature carbon and metal are introduced. Since the supply prevents the rise of the temperature of the sedimentation water to prevent various problems caused by the increase in the temperature of the conventional sedimentation water, the purpose is to maximize the safety and to completely prevent environmental pollution.

The object of the present invention is to form a sedimentation in the water tank tank by connecting the cooling tower with a drain pipe and a water supply pipe on the water tank tank which separates by-products such as high temperature carbon and metal generated by thermal decomposition of the waste tire into the sedimentation water therein. It is achieved by means of a sediment chiller for dispersion submersible, which forcibly drains the water by a pump and cools the sediment in the tank while recirculating and feeding it through the cooling tower.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment for achieving the object of the present invention will be described in detail.

As the present invention is shown in Figures 1 to 4,

The fragments from the waste tires are fed into the distillation furnace (5) through one side hopper (2) and moved by the screw (6) in the rotation of the distillation furnace to generate high heat and steam generators ( 8) The gas and steam generated through the thermal decomposition process by the high temperature steam injected by condensation through the cooling process by the cooler and the storage tank are condensed and the fuel oil is extracted. By means of means 20, 25, carbon, metal, etc. are separated,

The by-product primary separation means 20 is discharged by-product by the by-products into the sedimentation water in the tank tank 21 to discharge the by-product filtered on the floating and screen conveyor 22 and collected and precipitated at the bottom of the tank tank 21 By-products are collected by scraping and discharged by the discharge conveyor 23,

The by-product secondary separation means 25 is recycled by separating and collecting carbon, metal, etc. while again feeding the by-product separated to the screen conveyor 22 of the primary separation means and transported by the vibrating screen conveyor 26 again. In doing

The water tank tank 21 of the by-product primary separation means 20 is formed by connecting the cooling tower 31 to the drain pipe 21a and the water supply pipe 21b so that the precipitated water in the water tank tank 21 reaches a predetermined temperature or more (P1). Sedimented water forcibly draining through the drain pipe 21a and circulating through the water supply pipe 21b while being cooled through the cooling tower 31 by cooling the sedimented water in the water tank 21 below a predetermined temperature. Cooling means 30 is provided.

In addition, the cooling tower 31 has a separator 32 having an inclined screen 32 'on the upper side to separate the by-product from the sediment water drained from the water tank tank 21 to the upper left and right and filtered on the inclined screen. The by-products are separately collected along the slope, and the sedimented water collected in the separator is fed to the left and right cooling chambers 35 at the bottom for cooling.

The cooling chamber 35 is cooled by air sucked from the outside to the inside by the intake fan 37 in the center of the left and right cooling chambers 35 while the precipitated water is guided downward along the zigzag guide plate 36. It is collected at 38 and is circulated to the water tank 21.

At this time, the cooling tower 31 is formed in succession to form a plurality of separation cylinders 32, 33 having screens 32 'and 33' inclined to the upper left and right in upper and lower portions of the upper screen is finer than the upper screen. The sedimented water in the upper separator (32), which is first filtered through the upper screen, is passed through the lower screen to the lower screen to separate the by-products filtered in multiple stages on the upper and lower screens separately along the slope, and the lower separator (33). Precipitated water collected in the supply to the lower left and right cooling chamber 35 may be configured to cool.

Next will be a look at the operation and action of the subject innovation configured as described above.

 By thermal decomposition of the waste tire fragments in the drying furnace 5, by-products such as gas, steam, carbon, and metal are generated in the drying furnace 5.

The gas and steam condense through cooling with a cooler and a storage tank, thereby extracting fuel oil, and discharging the by-products such as carbon and metal to discharge carbon by-products 1, 2, and the second separation means 20 and 25. , Metal and so on.

In more detail, by-products such as high-temperature carbon and metal discharged from the drying furnace 5 are introduced into the sedimentation water in the tank 21.

As such, by-products such as high temperature carbon and metal introduced into the sedimented water reduce the temperature of the by-product by the sedimented water, thereby preventing the explosion hazard that may occur when colliding with the metal material.

In addition, the precipitated water is cooled by the cooling tower 31 because the precipitated water is rapidly raised to a high temperature (approximately 80 ° C. or more) by the by-products of high temperature carbon, metal, and the like introduced into the precipitated water in the tank 21 as described above. By continuously circulating and supplying the immersion water temperature in the water tank 21 is kept constant.

This is forcibly draining the sediment water through the drain pipe 21a connected to the water tank tank 21 by the pump P1 and supplying the sedimentation water to the separators 32 on the left and right sides of the cooling tower 31, respectively. By-products included in the sedimentation water are separated and discharged along the inclination of the inclined screen, and the sediment water passing through the screen is collected in the separator 32.

And once again the precipitated water collected in the upper separator 32 is supplied to the lower separator to separate the by-product contained in the precipitated water again by the inclined screen 33, the inclined screen 33 ' Particles are finer than the inclined screen 32 'of the upper separator 32 to separate smaller by-products and are separated and discharged along the inclination of the inclined screen 33, and the precipitated water passing through the screen is divided into It will be collected at (33).

The sedimented water collected in the separator 33 in the state of separating the by-products is guided downward along the zigzag guide plate 36 provided in the cooling chamber 35 on the lower left and right sides of the left and right cooling chamber 35. Cooled by the air sucked from the outside to the inside by the intake fan 37 provided in the center is collected to the lower collection chamber 38.

The precipitated water in the cooling state collected in the collection chamber 38 is recycled back into the tank tank 21 through the water supply pipe 21b, so that the temperature of the precipitated water in the tank can be kept low.

As described above, the present invention forcibly drains the sedimented water in the tank tank into which the by-products of high temperature carbon and metal pyrolyzed in the distillation furnace are introduced by a pump, thereby recirculating and supplying the water to the cooling tank via the cooling tower. It is to prevent the various problems caused by the conventional sediment temperature rise by preventing the sediment water temperature rise in the inside to maximize the safety as well as to have the effect of completely preventing environmental pollution.
