Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a PVB and a glass separator for automobile and construction waste-

More particularly, the present invention relates to a rapid precipitation apparatus for recycling wastewater generated during a glass processing process, and a method for rapidly separating raw materials from a raw material, By using the rotating force of the agitator, it is possible to separate PVB and glass from waste reinforced glass by using a device for separating the two materials, and reuse the PVB and glass as a raw material, and to reuse the wastewater generated during the process To a PVB and glass separator of waste reinforced glass for automobiles and architectures.

In general, wastewater generated in the glass processing (polishing) process can be separated by using aluminum or silicon-based inorganic salt as a coagulant, and it is possible to secure the quality of water recycled entirely through the water filtration system, It can be recycled.

However, PVB and glass can not be separated easily because PVB and glass are precipitated at the same time in PVB (polyvinylbutyral), glass, and water mixture as in the case of automobile and construction waste reinforced glass. This is because the specific gravity of PVB is 1.07 ~ 1.2kg / ℓ higher than water, and sedimentation occurs because of high water surface area load despite rising water flow.

In this case, PVB and glass having different specific gravity can be separated by using the rotational force of the spiral stirrer. However, since the water surface area is too low and turbulent flow occurs, PVB separated from the upper part contains a large amount of glass fine particles, PVB was contained in a large amount.

In addition, since the separation efficiency is further lowered when the fine grinding is performed, it is necessary to perform a pretreatment (grinding) of 5 mm or more. In this case, there is a problem that the glass is attached to the PVB as it is.

In addition, there is a chemical method using a solvent to separate the PVB and glass, but it takes an excessive amount of time to separate the treatment of the VOC material from the solvent and the PVB and the solvent, and in a general method of separating using water or brine A large amount of wastewater and wastes are generated and the economy is lowered.

Accordingly, the present applicant has proposed a method for simultaneously separating three components including PVB, glass and water as in the case of automobile and construction waste reinforced glass, and reusing and recycling all three separated components .

The present invention separates PVB and glass from waste reinforced glass by using a rapid precipitation device for recycling wastewater generated during the glass processing process and a device for separating the two materials using the specific gravity of the raw material and the rotational force of the agitator, The present invention relates to a PVB and glass separator for waste-tempered glass for automobiles and architectural uses using a wastewater-free method for reusing waste water generated in the process and reusing it in a no-refueling manner. The PVB and glass separator of waste reinforced glass for automobiles and architectural use using the waste water non-reflux method according to the present invention includes a powder mill 10, a quantitative feeder 20, a separation tank 30, a screen net 40, A filter 50, a filter press 60, a second micrometer 70, and a storage tank 80.

The powder crusher 10 is configured to crush the PVB used in the present invention and the waste reinforced glass for automobiles and architectures including glass into powder of 2 mm or less. When the waste tempered glass is pulverized to 2 mm or less in the powder crusher 10, the particle size of the PVB is maintained at 1 to 2 mm, but the glass is in a powder state of 1 mm or less.

The quantitative feeder 20 feeds pulverized waste-reinforced glass powder through a powder crusher 10 and dispenses the pulverized powder in a fixed quantity. An apparatus capable of supplying a fixed amount of a screw conveyor or the like as shown in FIG. 2 is used.

The pulp-reinforced glass powder discharged in a fixed quantity through the quantitative feeder 20 is supplied to the separation tank 30 together with water (reusable water). 1 and 2, the separating tank 30 is provided with a separating hood 31 in the form of a circular tube for receiving powder and water discharged from the quantitative feeder 20, And a propeller-type impeller 32 connected to a rotating shaft 39 driven by a motor 38 and pushing the powder and water outward while agitating the powder and water through a rotating force. The separating hood 31 and the impeller 32, outside the ice-installed navigation spaced in the PVB glass containing water it is lowered by the number of area load and gravity and containing the water is provided with a helical inclined plate 33 to rise by a rotational force and the upward flow and the helical inclined plate ( A discharge pipe 35 is formed in the upper part to discharge the PVB containing water raised by the spiral 33 and the lower part of the sinking part 37 is provided at the lower part to store the glass containing water lowered by the spiral- Is formed in the shape of a circular tube.

Through the waste glass powder and water while pushed out to the outside (edge side) helical inclined plate 33 of the cylindrical separation tank 30 when stirred with a propeller-type impeller (32) is put into the separating hood (31) of water The glass containing the part is lowered, and the PVB containing part of the water is raised.

At this time, since the impeller 32 may cause the glass to rise during the descent, the impeller 32 having a vertical shape or inclination of less than 15 degrees is used, and the number of revolutions of the impeller 32 is set to 15 to 20 rpm The width t of the impeller 32 is at least 10% of the height h of the helical swash plate 33 and the length of the impeller 32 is not less than 10% Is preferably set to 1/3 or more of the diameter (D) of the separation tank (30).

In the spiral wobble plate 33, the glass sinks due to the water surface area load and the gravity of the helical wobble plate 33 , and the PVB and water float to the top due to the rotational force and the upward flow. At this time , the helical swash plate 33 may be formed to have a flat plate-like inclined surface as shown in FIG. 3. However, as shown in FIG. 4, the inclined surface may be curved so that the PVB containing water can be easily raised, .

3, the helical swash plate 33 is installed at intervals of usually 100 mm or less in the case of the rapid precipitation plate for wastewater treatment. However, as shown in FIG. 4, in order to secure a smooth rising space of the PVB, And a separation hood 31 provided on the center side of the separation tank 30 for preventing clogging between the PVB and the spiral wobble plate 33 during an overload in which the glass is loaded in an amount larger than the capacity, ) Is preferably set to 40 to 60 mm.

It is preferable that the width W of the helical swash plate 33 is set to 1/4 to 1/2 of the diameter D of the separation tank 30. At this time, if the ratio is less than 1/4, the clogging phenomenon tends to occur. If the ratio is 1/2 or more, the separation performance is excellent, but the feed amount is decreased.

The angle k of the spiral type swash plate 33 is set to 60 to 70 degrees. The number of revolutions of the impeller 32 should be varied according to the inclination angle, and the number of revolutions is increased as the angle is increased.

The water and the PVB that are raised by the spiral type swash plate 33 are discharged through the discharge pipe 35 formed on the upper side of the separation tank 30 and are discharged by the screen net 40 connected to the discharge pipe 35 And PVB. The water discharged through the dehydrator 43 is filtered through the first microfilter 50 connected to the dehydrator 43 and used as the reused water. The filter 50 allows the use of a filter through which particles of 2 to 5 占 퐉 pass .

Between the screen net 40 and the first microfilter 50, a storage tank 45 equipped with an oil absorption nozzle 46 for removing scrap of waste reinforced glass contained in water or oil that may be adhered during transportation .

The glass containing water descending to the lower portion of the spiral type swash plate 33 is compressed by the filter press 60 connected to the settling portion 37 formed at the lower portion of the separation tank 30 to remove moisture and to remove water The separated glass is collected separately and recycled. The water discharged through the filter press 60 is filtered by a second micro-filter 70 connected to the filter press 60 and used as reused water do.

Between the filter press 60 and the second microfilter 70, a reservoir 65 equipped with an oil absorption nozzle 66 for removing scrap of waste reinforced glass contained in water and oil that may be adhered during transportation .

The upper layer water discharged through the discharge pipe line 35 can be used for a long period of time even if the first microfilter 50 through which particles of 2 to 5 탆 pass is used. However, the upper layer water is discharged through the settling portion 37 When the lower layer may have even been filtered by the filter press 60 to apply the same to the first micro-filter 50 is higher than the pollution level because the filter top layer can easily clog the second micro-filter 70 is 6~10㎛ To allow the particles to pass through, so as to maximize the operating time. The water having passed through the second microfilter 70 using the filter having the size of 6 to 10 mu m has no trouble in reuse and is not reusable even if a sand filtration device having a somewhat lower treatment efficiency is provided.

When the water filtered through the first micro filter 50 and the second micro filter 70 is continuously reused, turbidity and viscosity increase, so that the silicon (Si ) Or alumina (Al) based flocculants can be used to solve the problems of turbidity and viscosity while glass can be recycled.

Also, since the amount of water contained in the PVB and glass is about 30% (based on 1 day) of the capacity of the separation tank 30, it is possible to continuously reuse even if the reusing water is subjected to relatively simple filtering. (Si) or alumina (Al) based coagulants as described above, the pollution degree is regularly lowered, so that the waste water desalination system to be implemented in the present invention becomes possible.

And a storage tank 80 connected to the first microfilter 50 and the second microfilter 70 for storing the reused water discharged through the first and second microfilters 50 and 70 and supplying the reused water to the separation tank 30, The replenishing water supply tank 85 for supplying replenishing water of clear water is further connected to the storage tank 80. [

In the construction of the PVB and the glass separator of the waste reinforced glass for automobiles and architectural use using the waste water no-discharge system according to the present invention, the force acting in the separation tank 30 provided with the spiral wobble plate 33 is gravity, The floating force due to the supply and discharge of the water by the impeller 32 acts and the laminar flow state in which the turbulence does not occur inside the helical swash plate 33 can be separated from the PVB only.

Further, clogging may occur in the helical swash plate 33 or the separation hood 31 depending on the amount of the raw material supplied. When pumping is performed to remove the glass settled to the lower part of the separation tank 30, Since the power is applied to the rising speed, the normal operation state can be maintained by increasing the circulating water quantity by the same amount instantaneously.

If the supply of the raw material to the separation tank 30 is cut off and the PVB is completely removed, the filter press 60 can be operated. In this case, the continuous operation can not be performed. The circulation water for keeping the residence time at about 10 minutes is automatically supplied and the supply amount is increased by an amount that is exited when the pump of the filter press 60 is operated.

In the case of the filter press 60, since the amount of pumping is not always constant, an automatic flow measuring device (not shown) is installed and programmed to operate in conjunction with the amount of circulation, and the amount of circulation is automatically controlled Device and a flow control valve (not shown).

The supply amount of the raw material supplied into the separation tank 30 allows the driver to adjust the rotation speed of the fixed amount feeder 20 and the rotation speed of the impeller 32 is controlled by the driver .
