Description

Sludge Separation Treatment Device Using Compression Separation}

The present invention relates to a sludge separation and treatment device, and more specifically, to separate industrial waste eroded from rivers or reservoirs or reservoirs storing industrial waste from wastewater, and the sludge contained in the wastewater is separated by solidification by a compression method. It is about the device being processed.

As industries become highly developed, the severity of environmental pollution is becoming more and more serious. In particular, wastewater, factory wastewater, and livestock wastewater discharged from homes, factories, or livestock farms flow into groundwater and rivers and eventually pollute the sea.

If these wastewaters are discharged without treatment and purification, various organic substances, microorganisms, nitrogen (N), phosphorus (P), etc. will cause sublimation of rivers, etc., which will not only destroy the aquatic ecosystem but also cause soil contamination. It inevitably threatens humans' right to survive by causing destruction to the living environment and the ecosystem's food chain.

Of course, in order to reduce such damage, it would be most desirable to fundamentally reduce the discharge of wastewater, but as industry develops, the discharge of various types of wastewater is inevitable.

Typically, sewer pipes are buried underground, and wastewater discharged in everyday life is transported to a certain location through these sewer pipes. Even in densely populated urban areas, streams or rivers (hereinafter referred to as 'river beds') can sometimes be found flowing. If such wastewater is discharged without separate treatment, the river beds are bound to be polluted.

In particular, recently, as efforts are being made to develop all surrounding roads and buildings while preserving the previously clean river bed, such as the Cheonggyecheon development project, pollutants (hereinafter referred to as 'sludge') in wastewater are being removed. There is an urgent need to develop a water treatment system that can preserve the riverbed in a clean state by filtering it separately and supplying relatively clean water (hereinafter referred to as 'sewage') back to the riverbed.

A water treatment system and method were proposed as a solution to the above problems.

Among them, there is a fluidized bed gasification device, which has been used in various chemical process fields such as alternative energy development and waste treatment, and in energy conversion processes and energy recovery processes related to gasification of coal, sludge, waste polymers, waste wood, and waste tires. , extensive research on this is underway.

Such a fluidized bed gasification device, for example, an organic waste gasification device, fills the inside of a gasification reactor with a fluidized bed material, introduces air through a plurality of spray nozzles installed at the bottom of the gasification reactor, and causes the fluidized bed material to flow with the air, The flowing fluidized bed material is preheated using a gas burner or oil burner to a temperature sufficient to gasify organic waste, and organic waste such as sewage sludge, waste wood, and waste plastic is introduced into the gasification reactor filled with the preheated fluidized bed material. It is configured to achieve gasification.

In addition, char, which is the residue of gasification completed in the gasification reactor, and fluidized bed material are supplied to the combustion reactor to combust the char through the high heat of the combustion reactor, and the fluidized bed material heated to high temperature is supplied to the gasification reactor to facilitate gasification. It is structured so that it can be done.

However, the use of gas burners or oil burners to gasify waste had the disadvantage of increasing carbon emissions and causing adverse environmental effects.

The sludge separation and treatment device using compression separation in the present invention will be described with reference to FIG. 1, largely comprising a storage tank 110 in which industrial waste is separated into wastewater and sludge in the internal space, and an upper side of the storage tank 110. It is installed inside the wastewater suction unit 140, into which industrial waste flows, and the pump unit 120, which discharges the wastewater separated from the inside of the storage tank 110, and the storage tank 110, to compress the sludge of industrial waste. It may include a sludge compression separation unit 130 that separates the sludge by solidification.

The pump line 122 is connected to a pump 121 installed on the outside of the storage tank 110, and the pump 121 is driven by power application to pump wastewater suspended at the upper side within the storage tank 110. It is discharged.

The pump 121 may be a centrifugal pump that draws fluid into the center of a cylindrical container containing a rotary compressor (not shown) with wings.

In addition, a filtration filter 124 may be further installed in the pump line 122 leading to the inside of the storage tank 110 to filter out fine sludge contained in the wastewater.

The filtration filter 124 has a diamond shape and is installed on the side wall of the storage tank 110 with a pump line 122 therein, and may be installed to be detachable or removable depending on the case.

The filtration filter 124 may be a metal mesh network and may further include non-woven fabric.

Again, the storage tank 110 may include a sludge compression separation unit 130 inside which compresses the sludge of industrial waste and separates it by solidification.

The sludge compression separation unit 130 may be composed of a push cylinder 132 and a mesh compression body 134 that slides by the push cylinder 132.

The push cylinder 132 is installed at the center of the upper surface of the storage tank 110, and the cylinder rod 132a, which operates as a piston from the push cylinder 132, may be located at the inner center of the storage tank 110.

The push cylinder 132 may be a pneumatic or hydraulic cylinder.

Additionally, a mesh pressing body 134 may be installed on the end side of the cylinder rod 132a operated by the push cylinder 132.

The mesh compressor 134 slides along the inside of the storage tank 110 to float the wastewater to the upper side and compress the sludge while moving it to the lower side.

That is, the mesh compactor 134 is a device that separates wastewater and sludge contained in industrial waste.

The mesh pressing body 134 is a mesh network as shown in the perspective view in FIG. 3, and may preferably have a cone shape with the central portion protruding from the lower surface.

Moreover, the mesh press body 134 has a rubber ring (134a) or a Teflon ring installed on the outer circumference, and is the same as the inner circumference diameter of the storage tank 110, so that it can be slid in the vertical direction along the inside while separating the storage tank 110. You can.

In addition, the lower surface of the mesh compressor 134 protrudes in a cone shape, and a cylinder rod 132a is connected to the protruding portion to help compress the sludge, and has the same shape as the storage tank 110 whose width narrows at the bottom. More efficient compression may be possible.

And the wastewater suction unit 140 is installed on the upper side of the storage tank 110 to allow industrial waste to flow in.

As shown in FIG. 2, the wastewater suction unit 140 is installed to communicate with the inlet 114 of the storage tank 110, and can be mounted and removed from the frame 102.

The wastewater suction unit 140 in the perspective view shown in FIG. 4 includes a receiving body 142 having a rectangular shape with an upper opening and a receiving space 142a provided as an edge having a height, and the receiving space 142a. It may include a suction hole 146 that is installed eccentrically and communicates with the inlet 114 of the storage tank 110.

The bottom of the receiving space 142a is inclined to one side, and the suction hole 146 may be located at the bottom of the inclined surface.

The suction hole 146 may be formed on the edge side of the receiving body 142.

Next, the suction hole 146 will be described with reference to FIGS. 6(a) and 6(b).

Figure 6(a) is a plan view of the suction hole 146, and (b) is a side cross-sectional view of the suction hole 146.

The cross-sectional area of the suction hole 146 decreases downward, and the suction hole 146 may extend from the suction hole 146 to further form an inlet surface 146a.

The inflow surface 146a has a groove shape, has a certain depth, and may be formed on the front side of the suction hole 146 in a straight or curved shape.

The differential pressure of the fluid may be reduced by forming the inlet surface 146a.

More specifically, when looking at the suction hole 146 from the side, the fluid first flows smoothly into the round-shaped inflow surface 146a with a certain depth, and the inflow fluid has a cross-sectional area from the entrance side of the suction hole 146. By reducing the flow rate of the fluid, the fluid flow can become faster and the fluid flow can become smoother.

Meanwhile, as shown in FIG. 4 or 5, the wastewater suction unit 140 is made of stainless steel and can be mounted and removed from the frame 102.

A coupling portion 149 formed at each corner of the receiving body 142 to surround a portion of the outer circumference of the frame 102 and forming coupling pieces 149a in the vertical direction at both ends, and the remaining portion of the outer circumference of the frame 102. It is composed of a fixing part 148 that surrounds and forms a fixing piece 148a to be slidably coupled to the coupling piece 149a, so that the receiving body 142 can be mounted and removed from the frame 102.

The coupling portion 149 may have a “L” shape or a hemispherical shape depending on the formation of the frame 102, and the upper, lower, and one side may be open to cover a portion of the frame 102, that is, half.

Additionally, both ends of the open coupling portion 149 may be extended, and the extension portion may be bent in an “L” shape to form a coupling piece 149a in the vertical direction.

On the contrary, a fixing part 148 corresponding to the coupling part 149 may be installed at each corner of the receiving body 142 integrally or by welding.

The fixing part 148 is coupled to the remaining part of the frame 102 on which the coupling part 149 is formed, and the upper and lower sides and one side facing the frame 102 are open so that it can wrap a part of the frame 102, that is, half. there is.

The fixing part 148 may be bent in an “L” shape with one open side corresponding to the “L” shaped coupling piece 149a, thereby forming a fixing piece 148a in the vertical direction.

Therefore, with the fixing part 148 of the receiving body 142 positioned on each frame 102, the coupling part 149 is positioned on the upper side of the frame 102 to surround a portion of the frame 102, and then combined. The portion 149 was slidably moved downward so that the coupling piece 149a and the fixing piece 148a were slidably coupled to face each other.

In the above state, the suction hole 146 of the receiving body 142 is supported by the inlet 114, and separation of the fixing part 148 and the coupling part 149 can be prevented.

The sludge separation and treatment device using compression separation according to the present invention configured as described above will be described again with reference to FIGS. 1 to 6.

The receiving body 142 of the wastewater suction unit 140 is mounted on the inlet 114 side of the storage tank 110.

First, the receiving body 142 is mounted on the frame 102, which means that the fixing portion 148 of the receiving body 142 is positioned on each frame 102 and is moved to the upper side of the frame 102. ) After positioning the coupling portion 149 to surround a portion of the coupling portion 149, the coupling portion 149 was slidably moved downward so that the coupling piece 149a and the fixing piece 148a were slidably coupled to face each other.

Conversely, detachment may be possible by sliding the coupling portion 149 upward to remove the coupling piece 149a from the fixing piece 148a.

As described above, the receiving body 142 is coupled to the frame 102 so that the suction hole 146 of the receiving body 142 communicates with the inlet 114.

Subsequently, industrial waste is poured into the receiving space 142a of the receiving body 142, and a certain amount of industrial waste in the receiving space 142a flows through the inlet 114 along the inlet surface 146a and the suction hole 146. The inflow occurs inside the storage tank 110.

At this time, industrial waste is collected on the inlet surface 146a along the slope of the receiving space 142a, and the lower cross-sectional area of the suction hole 146 is reduced so that the industrial waste can quickly flow into the inlet 114 by reducing the differential pressure.

As described above, when the inside of the storage tank 110 is filled with industrial waste, the mesh press body 134 on the upper side of the storage tank 110 is moved to the cylinder rod 132a by operation of the push cylinder 132 by the control unit. ), the sludge contained in the liquid industrial waste is dragged downward and compressed. Contrary to the compressed sludge, the wastewater floats to the upper side of the storage tank 110 and is discharged by the pump unit 120. It becomes.

The mesh compressor 134 can be repeatedly slid along the storage tank 110 and can solidify the sludge collected on the lower side of the storage tank 110 by compressing it.

Then, the solidified sludge is discharged to the discharge port 112, and can be sequentially discharged through a discharge pipe equipped with a screw, as shown in FIG. 1.

According to the above, the sludge contained in wastewater is separated and treated by solidification by a compression method using a push cylinder and a mesh compressor, thereby achieving excellent efficiency at low cost without the need for a combustion process using a burner, etc.

In addition, the wastewater suction part is manufactured to be detachable and attachable, so it can be washed separately when not in use, making it possible to use it semi-permanently.

Meanwhile, it may include a control unit (not shown) that controls the operation of the pump 121 and the push cylinder 132.

The control unit can control the operation of the pump 121 and the pump amount, and accordingly, a water level sensor can be further installed in the storage tank 110.

Additionally, the control unit can control the push cylinder 132 to adjust the degree of compression of the sludge. Therefore, a camera or pressure sensor may be installed in the storage tank 110.

Such a control unit may be a concept that includes at least one processor, memory, and storage device. Here, the processor may execute program commands stored in memory and/or storage. The processor may refer to a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor on which methods according to the present invention are performed.
