Description

Disposal equipment of impurities, including to remover oily and fatty matter

The present invention relates to a contaminant treatment apparatus having a fat and oil component removal function capable of treating debris by filtering and separating various solid materials contained in waste liquids such as manure, sewage, and livestock waste water. will be.

<Preparation Method of Manure, Sewage, Livestock Wastewater, etc.>, which is an invention (patent publication No. 2004-65196) (hereinafter referred to as background art) previously filed by the present applicant, is used to filter medium and large contaminants on a rotary screen and to filter the filtrate. The remaining sand is sorted by size in the sand separator, and the coarse sand is separated firstly, and the remaining small sand is composed of secondary filtration and dehydration by liquid cyclone and centrifugal dehydrator.

However, the amount of contaminants, especially manure, that is introduced in one treatment plant varies in composition and properties depending on the place of occurrence and season, and in particular, the particle size and quantitative ratio of the inflowed sand are often changed. It is very difficult to determine the reality. In addition, since the sand deposited on the bottom of the manure collection vehicle is concentrated into the treatment device at the end of the input, it may cause the function of the sand separator to not function properly or may cause a close phenomenon.

In addition, in the case of manure treatment, the target liquid can be classified into conventional collected manure, septic tank sludge, and concentrated sludge of sewage treatment facilities, and cleaning liquid of sedimentation tank. In the basement of apartment houses and large buildings, most sewage treatment facilities are installed to collect and treat all waste liquids from the kitchen or bathroom together with manure and merge them together. The concentration and sedimentation tanks included in this treatment facility are included. The back is cleaned regularly or irregularly, and the cleaning solution is put into the manure treatment plant for disposal.

However, in particular, the cleaning liquids collected from sewage treatment facilities in densely populated restaurants or buildings with large meal facilities often contain a large amount of oils, which are mainly edible oils. It is not mixed with it, and it spins off and is brought into the manure treatment plant together with the cleaning liquid.

The oil and fat component does not easily pass through the filtration hole because the surface tension and viscosity is greater than the water, it acts as a cause of problems in the filtration and dehydration process, in particular, the screw press for dehydration. As a result, the filtration and dehydration performance is significantly lowered, and in severe cases, dirt may be flooded in the screw press by preventing the progress of the dehydrated material. Moreover, in winter, oils are strongly entangled and not easily released, causing more damage.

1) Effect of sand filtration dewatering

In the background art, it is actually very difficult to set the size criteria in the sand separation process. For example, if the standard is set to 3 mm and only the larger size is removed first, and the smaller size sand is dehydrated in a centrifuge (Screw Decanter), if a large amount of sand containing less than 3 mm is introduced, If the load is lowered and the standard is lowered to 1mm or 2mm, the centrifuge can be operated smoothly, but the instantaneous concentration of sand is concentrated due to the large amount of instantaneous sand in the sand sorting process. Sand may also cause closure.

In addition, when a large amount of sand is separated and separated at a time, the separated sand flows directly into the next step, the screw press, and the sand is aggregated together so that it is not properly mixed with other contaminants, thereby reducing the dehydration effect of the screw press. Of course, the undesirable phenomenon that the sand escapes into the dehydration hole will occur.

This phenomenon is due to the variable content of the sand content, the distribution of the size, etc. vary depending on the type of material to be introduced, and the present invention is effective in the unpredictable variable factors of the sand inflow situation. It is configured to respond.

That is, the present invention eliminates the sand separation process of the background art and sends all the desorption liquid filtered from the rotary screen (1) to the wedge bar filter (2), which is a fine contaminant filtration process to filter all solids including sand that is approximately 1 mm or more. By sending to the press (5) and the remaining filtrate removed from the wedge bar filter (2) via the liquid cyclone (3) to the centrifuge (4) it is possible to significantly reduce the load of the centrifuge (4). In this way, since only about 1 mm or less of sand flows into the centrifuge (screw decanter) 4, it is possible to prevent overloading of the screw decanter 4 at the source, and also to reduce energy such as size and power. Occurs.

Since sand of about 1 mm or more, which is filtered in the wedge bar filter 2 and passed to the screw press 5, is sufficiently mixed with other solids while passing through the wedge bar filter 2, problems resulting from unmixing, such as a background art, are caused. It is eliminated and the dewatering effect in the screw press 5 is improved.

This does not solve the problem of sand treatment by removing the sand separator from the background and simply moving the wedge bar filter in place. In this case, unlike the background art, where sand is hardly introduced into the wedge bar, since most of the incoming sand is introduced into the wedge bar filter, sand of particles having a size similar to that of the wedge bar (2ba) is filtered. It is very likely that you will get caught in. At this time, in order to remove the constricted stiff sand, the washing water of a very strong blow force is required as compared to the background technology in which only soft general impurities are introduced. Accordingly, unlike the background art, a high pressure pump and a nozzle are required, and in particular, the amount of washing water used and required energy are excessive. Therefore, it is impossible to practice the present invention in which sand having a size similar to that of filtration trees is introduced using a conventional cleaning device such as a wedge bar filter of the background art.

Therefore, the present invention utilizes a linear reciprocating washing device to exert a powerful blow effect with a small amount of washing water, so that sand is confined in the gap of the wedge bar even when 1 mm of sand having a size similar to that of the filtration tree is introduced. Since it is possible to prevent the phenomenon is to be able to perform filtration without difficulty, the configuration of the present invention is possible.

As a result of comparing and experimenting the effect of the linear reciprocating washing apparatus 2a of the present invention against the fixed water pipe of the background art, the present invention had about 55% water saving effect compared to the background art, and the facility power was increased. Is 80%, and the power used is 62%.

Details of this experiment and its effects will be described separately in the detailed description of the invention.

2) Dehydration effect of oil and fat component

The dewatering main body of the screw press is divided into the inlet part where the dehydrated material descends and the subsequent compression dewatering part. The inlet part receives the material to be dehydrated and transfers it to the compression dewatering part. In the process, the free water of the contaminant is separated and falls into the filter hole, and the compression dewatering part compresses the material from the inlet part. It is known to act to dehydrate.

This screw press's dripping action on oil-based contaminants shows that, first, at the inlet, since no artificial compressive force is applied, it is seen through filtration rather than dehydration. Because of the large surface tension and viscosity acting in all directions of the hole and very easily entangled, negative effects such as passing through a hole of 10 mm diameter, such as through a hole of 7 mm or less in diameter, result in good filtration. It won't work.

However, when the inlet of the inlet is a long straight so-called slit shape instead of a circular shape, the surface tension acting on the filtration hole acts only in two directions facing each other, compared to the circular filtration hole. Dripping effect is greatly improved.

Particularly, it is a filter body forming a slit-type filter hole, and the cross section is formed using a wedge-shaped rod 5a having an isosceles triangle, so that the gap is widened toward the outside, so that the fine solid once passing through the slit does not stay in the gap. It can be easily pulled out, which can double the filtering performance.

Next, when the dehydration part is operated, a strong crushing force acts as the cross-section becomes narrower as it proceeds, so that even if the dehydration hole is circular, the desorption liquid can be easily discharged to the outside, so that the filtration of the dehydration part is circular. The ball may be applied as it is.

In addition, a pressure watering device (5b) having a plurality of injection nozzles (5bb) in the upper part of the inlet is arranged, the injection hits the inner circumferential surface of the inlet cylinder to puncture the filter neck gap of the inlet to maintain the sol / gel state It breaks down the ingredients and helps the filtration gap to pass through. It also increases the dehydration effect by not allowing oils and fats to get into the compression dehydration unit.

In the screw press (5), the dehydration effect depends primarily on the compression effect, so that various condensed materials are well mixed and mixed to deliver the compressive force evenly and the dewatering performance is improved. That is, the fat and oil components should be finely dispersed and distributed evenly between the solids, so that the negative characteristics of the fat and oil components are not expressed, so that the dehydration effect can be increased.

As a result, the contaminant treatment device having the oil-fat removal function of the present invention made as described above can cope with any conditions such as the amount of sand, the distribution situation by size, and the temporal fluctuation of inflow in sand treatment, thereby improving the sand filtration dehydration effect. It is also possible to improve the imperfection of filtration due to the nature of the oil in the treatment of the oil component newly emerging need.

The main problem in the process of removing various contained solids, which is the basis for the treatment of manure, sewage and livestock wastewater, is the removal of fine contaminants (approximately 1 mm), the smoothness of sand removal, and the removal of oily components Three problems can be cited.

The basis of such judgment is first, the necessity of advanced treatment is increasing due to the strengthened regulation of effluent water quality and the reduction of dewatered sludge under the London Convention. It precipitates in various tanks and reduces the depth and capacity of the tank, which adversely affects the entire treatment process. Sand components to be removed at the beginning of the treatment process are mainly separated by high-speed rotation such as screw decanter. Due to the very large centrifugal effect (usually expressed as a G value) acting inside the centrifuge, it is easy to cause excessive load, and there is a problem that an overload occurs even if the amount of sand inflow is slightly larger than the designed value or the particle size is slightly larger. Third, the problems caused by the contaminants of fats and oils Recently, due to the problem of difficult to filter, dehydration, and separation of the waste oil component, which has been greatly increased, it is expected that a complex treatment apparatus having various functions and reliable processing performances is required by adapting to a different processing environment.

Among the above three important issues that can be considered regarding the process for treating the waste liquor, the fine contaminant filtration problem can be solved in the above-described invention, but the remaining two problems can be solved through the present invention. The present invention will solve the important problems of the waste liquid contaminant treatment system such as manure at the same time will have the effect of greatly improving the overall treatment level.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to the drawings, the contaminant processing apparatus having a holding component removal function according to the present embodiment includes an input device 6 for internally flowing a processing object introduced from the outside along a predetermined path, and The first tank 7 and the first tank 7 as well as the first tank 7 installed in the lower portion and communicating with the feeding device 6, and the second tank 9 located behind the first tank 7. And a third tank 13 provided between the two tanks 9.

In addition, the rotary screen (1) is provided at the communication portion of the input device (6) and the first tank (7). The rotary screen (1) is fixed to a plurality of cylindrical filter medium to be spaced apart at a predetermined interval to take a substantially cylindrical form and rotates by a motor.

Basically, the rotary screen (1) is to filter the particles that are relatively large in the size of the contaminants in the workpiece to be introduced into the outer peripheral surface of the cylinder, that is, the filter material is filtered through the filtration gap of the rotary screen (1) is screwed It moves downward to the press 5 side. Water and small contaminants of small size that have passed through the filtration gap of the rotary screen 1 fall to the bottom and are collected in the first tank 7.

In addition, a wedge bar filter 2 having a water injection part is provided inside the second tank 9. The wedge bar filter (2) receives the to-be-processed object collected in the first tank (7) therein, the so-called fine to play a role of filtering smaller contaminants that the rotary screen (1) has not filtered out It is a filter.

Between the said 1st tank 7 and the wedge bar filter 2, the 1st pump 8 for sending the to-be-processed object collected in the 1st tank 7 to the wedge bar filter 2 is provided. The first pump 8 pumps the object to be processed in the first tank 7 and pumps it to the wedge bar filter 2.

For convenience of description, with reference to FIGS. 7 to 15, a detailed description of the wedge bar filter 2 having the reciprocating washing apparatus 2a will be given first.

As shown, the filtration cylinder 2b of the wedge bar filter 2 according to the present embodiment has a cross-sectional shape of an isosceles triangle and has a plurality of rod-shaped wedge bars 2ba extending in a longitudinal direction in a cylindrical shape. It is divided into one filtration part and an outlet part which is fixed to the end of the filtration part and has a plurality of solid water outlets 2bc formed along the circumferential direction. The filter portion and the discharge portion have the same center of rotation axis and the cylinder inner diameter of the discharge portion is not smaller than the inner diameter of the filter portion.

In addition, the filtration cylinder (2b) is rotated by receiving a rotational force from the drive motor (not shown) via the sprocket (2be) in a state in which the central axis extending from the center of both ends to the outside of the cylinder is supported by the bearing (2bd). . In addition, the wedge bar filter inlet (2bb) is provided at the filtration side side end of the filtration cylinder (2b). The wedge bar filter inlet (2bb) is a hollow shaft to guide the workpieces pumped by the first pump (8) through the inner space of the shaft into the filtration cylinder (2b).

On the other hand, each of the wedge bar (2ba) takes a substantially triangular cross-sectional shape, as shown in Figure 8 and spaced apart at regular intervals to provide a slit therebetween. At this time, the wedge bar has a rhombic faucet on the triangular acute portion of the cross section so that the faucet is inserted into the groove of the fixed frame (2baa) to form a cylindrical shape as a whole. Of the contaminants in the workpiece to be poured into the filtration cylinder 2b, the contaminants and water smaller than the width of the slit escape into the gaps between the wedge bars 2ba and the remainder remain in the filtration cylinder 2b.

In addition, the filtration cylinder 2b is disposed to be inclined downward toward the third tank 13 side as shown in FIG. 1. Therefore, the contaminants left in the filtration section of the filtration cylinder 2b move to the discharge side according to the rotation of the filtration cylinder 2b and finally fall downward through the solid water outlet 2bc.

However, as described above, since the contaminants smaller than the slit widths between the wedge bars 2ba pass through the slits and escape downward, the contaminants (particularly sand) of a size substantially similar to those of the slits are between the wedge bars 2ba. It can get stuck in the slit and block the discharge of water or small sized debris. If the slit is partially blocked, the filtration performance of the filtration cylinder 2b is lowered.

Accordingly, a water spray unit, that is, a reciprocating washing device 2a, is installed on the filtration cylinder 2b. The water spraying unit sprays water of strong water pressure into the filtration unit of the filtration cylinder 2b to separate the contaminants stuck or stuck to the slit from the slit. In particular, in the present embodiment, the nozzle 2ab of the water spray unit is configured to reciprocate along the longitudinal direction of the wedge bar 2ba, thereby effectively washing the water in a wider range with a smaller quantity. The results of one experiment, which will be described later, will fully illustrate the effect of the reciprocating injection method of the present invention against a fixed injection method such as background art.

The water spray unit includes a washing water pipe 2aa disposed in parallel with the filtration cylinder 2b on the upper side of the filtration cylinder 2b, and a plurality of nozzles 2ab provided in the washing water pipe 2aa. The washing water pipe (2aa) is supported by the carver (2c) serving as a frame to be movable in the longitudinal direction through the axis (2aca, 2aha) for linear motion.

In addition, the connecting rod (2ac) is connected to the extension end of the washing water pipe (2aa), the connecting rod (2ae) is linked through the hinge portion (2ad). In addition, the connecting rod (2ae) is connected to the eccentric shaft (2af) is coupled to the shaft of the reduction motor (2ag). The eccentric shaft (2af) rotates when the reduction motor (2ag) is driven to draw an arc having a constant diameter.

Therefore, when the deceleration motor 2ag is driven and the eccentric shaft 2af rotates (circumferentially), the connecting rod 2ae and the connecting rod 2ac follow (just like a connecting rod and a crankshaft of an internal combustion engine of an automobile), and eventually the washing water pipe is driven. Reciprocate (2aa) in the longitudinal direction.

As long as it can reciprocate the washing water pipe 2aa, other types of driving devices may be applied. For example, linear reciprocating power cylinders, hydraulic or pneumatic actuators may be used.

In addition, in order to supply water to the washing water pipe (2aa) is provided with a washing water pump 12, an extension pipe (2ah) and a fluid pipe (2ai). The extension pipe 2ah is a general pipe and the flow pipe 2ai is a pipe that can be bent. The fluid pipe 2ai is deformed according to the reciprocating motion of the washing water pipe 2aa so as not to interfere with the linear movement of the washing water pipe 2aa.

The washing water pump 12 pumps water provided from the outside and is sent to the washing water pipe 2aa through the extension pipe 2ah and the fluid pipe 2ai.

In any case, the water pumped into the washing water pipe 2aa by the driving of the washing water pump 12 is sprayed toward the outer peripheral surface of the filtering portion of the filtration cylinder 2b through each nozzle 2ab. The sprayed water passes through the slits between each wedge bar 2ba and removes impurities from the slits fixed to the slits.

12 is a cross-sectional view for explaining another example of the wedge bar filter 2 shown in FIG.

Hereinafter, the same reference numerals as the above reference numerals denote the same members having the same function.

As shown in the drawing, the filtration cylinder 2b may be manufactured so that a plurality of ring-shaped wedge bars 2ba are arranged side by side to take a cylindrical shape entirely. The ring-shaped wedge bar 2ba is a round wedge bar (without taps) of FIG. 9, and is fixed in a predetermined width in parallel with each other by a combination of a plurality of straight rods 2bab, and toward the outside. Of course, a gap is formed.

In particular, as shown in Figure 15, the wedge bar (2ab) may be manufactured in the form of a polygon rather than a ring. It is the same as a ring-shaped filtration cylinder except that a unit filter body changes from said ring shape to a regular polygon.

Returning to FIG. 1 again, the description will be continued.

As described above, the object to be processed in the first tank 7 which is pumped to the wedge bar filter 2 by the action of the first pump 8 is introduced into the filtration cylinder 2b through the wedge bar filter inlet 2bb. When moved, the filtration cylinder (2b) is rotated by receiving a rotational force from an external drive motor, and filters the contaminants in the workpiece. At this time, the contaminants and water having a size smaller than the slit width of the filtration cylinder 2b are collected through the slit and collected in the second tank 9.

In addition, the contaminant having a size that does not pass through the slit is moved to the discharge side according to the rotation of the filtration cylinder (2b) and then falls down through the solid outlet (2bc) of the discharge portion is sent to the screw press (5) side.

In the process, the water spray unit sprays water on the outer circumferential surface of the rotating filter cylinder 2b to block the contaminants from sticking to or sticking to the slits, and separates the adhered or stuck contaminants from the slits. Reference numeral 11 is a wash water storage tank.

Next, the filtrate collected in the second tank 9 moves to the cyclone 3 by the operation of the second pump 10. The contaminants moved to the cyclone (3) is separated into a liquid and a solid by the specific gravity difference according to the rotational centrifugal force acting inside the cyclone (3), the liquid is discharged to the outside through the upper drain and mainly composed of sand, seeds The solids are introduced into the lower screw decanter 4 and dehydrated therein, and then discharged to the outside of the apparatus through the sand conveyor 16, and the separate conveyor 17 receives the dehydrated solids and is taken out to the next process.

On the other hand, the chute (5e) is provided on the top of the screw press (5). The chute 5e is a kind of hopper that guides the contaminants filtered by the rotary screen 1 and the wedge bar filter 2 to the bottom thereof.

Referring to the screw press 5 through the 16 to 18 as follows. This screw press 5 together with the wedge bar filter 2 described above is a key element of the invention.

Referring to the drawings, the screw press 5 of the present invention comprises a dewatering body and a pressure water sprinkling device 5b, wherein the dewatering body comprises a screw 5d arranged horizontally and the screw 5d. It is formed of a special shape cylinder 5c wrapped.

The cylinder 5c has a double structure. That is, the left half in the drawing is a cylinder manufactured in the form of a semi-cylinder opened upward by using a plurality of wedge-shaped rods 5a, and the remaining rear portion is a cylindrical cylinder having a plurality of through holes 5ca.

The wedge-shaped bar (5a) is a rod member having a cross-sectional shape of an approximately isosceles triangle as shown in Figure 18 to form a semi-cylindrical shape that is opened upward by coupling to the circumferential frame (5aa) and the reinforcing frame (5ab) Form. The cylinder made of the wedge-shaped rod 5a has a very excellent discharge capacity of the flow material as compared to the circular through-hole as described above because the slits are formed at regular intervals between the wedge-shaped rods 5a. .

Thus, for example, it is excellent for discharging oily contaminants with high viscosity to the bottom.

The screw 5d is a known one, and receives a rotational force from a motor (not shown) through a sprocket 5g to axially rotate and transport the contaminants received from the upper side to the dehydration contaminant discharge port 5i.

On the other hand, a pressure watering device (5b) is provided on the dewatering main body of the screw press (5). The pressure water sprinkling apparatus 5b extends in the longitudinal direction, and as the length thereof extends, a sprinkling pipe 5ba having a smaller diameter, a plurality of nozzles 5bb mounted to the sprinkling pipe 5ba and spraying water downward, A watering pump 15 for pumping water into the watering pipe 5ba is included.

The pressure water spray device (5b) is to inject water into the inlet portion of the screw press (5), that is, to prevent the aggregation of oil and fat components of the component by cleaning the slit of the wedge-shaped rod (5a) .

Some of the contaminants that fall down through the chute 5e pass through the slit of the wedge-shaped rod 5a and are collected in the third tank 13 together with water. The miscellaneous material which has not passed through the wedge-shaped rod 5a is compressed by moving backwards (right in the drawing) by the operation of the screw 5d. As the contaminants are compressed, the water contained in the contaminants is squeezed out and discharged through the through holes 5ca.

Reference numeral 5da denotes a cross-sectional area control. The cross-sectional area control opening (5da) is a zone where the flow cross-section of the contaminant gradually decreases.

19 is a view showing that a heater 5bc can be added to the pressure water spray device 5b. The heater 5bc doubles the function of removing the oily contaminants by heating the water to be sprayed in advance.

5 and 6 show a configuration in which the cyclone 3 and the screw decanter 4 are excluded in the contaminant processing apparatus according to the present embodiment. The cyclone 3 and the screw decanter 4 may be omitted according to a later step.

On the other hand, Figure 7 is a view showing the configuration of the conventional water spray, that is, the stationary washing device of the background wedge filter.

As shown in the drawing, a plurality of nozzles 2ab and 2aba are very closely arranged in the washing water pipe 2aa of the conventional water spray unit. The nozzles are arranged in this way because the nozzles cannot be reciprocated along the longitudinal direction of the filtration cylinder 2b.

Hereinafter, the characteristics of the contaminant treatment apparatus having a fat or oil component removing function according to the present invention will be described in earnest with a focus on the treatment of fat and oil components with sand treatment.

1) Means for increasing the effect of sand filtration dehydration

The present invention, the desorption liquid separated in the first filtration process of the contaminants using the rotary screen (1) the first step In the background technology, which is configured to separate the sand by size by sending it to the sand separation process, which is the second process, the sand separation process is eliminated. Instead, all the desorption liquid of the rotary screen (1) is introduced into the wedge bar filter (2) and filtered. Filtered contaminants are sent to the screw press (5) and the desorption fluid is transferred to the liquid cyclone (3) as a component. By this means, all remaining contaminants, including sand of approximately 1 mm or more, are removed from the wedge bar filter (2). By filtering and dehydrating only the sand particles having a size of about 1 mm or less with the subsequent centrifuge (4), the load caused by sand can be greatly reduced, preventing overloading of the centrifuge and increasing the dehydration performance. will be.

In this case, when the sand having a particle size of about 1 mm or more is introduced into the wedge bar filter 2, the sand particles having a size similar to that of the filtration tree may be caught in the gap of the filter tree (1 mm in size). By utilizing the technical means of the linear reciprocating washer 2a in the outer circumferential surface cleaning process of the wedge bar filter 2, the problem of sand stenosis can be solved by exerting a strong cleaning effect even with a small amount of water. Because of this, this new configuration is possible.

2) Dehydration means of oil-based contaminants

In the conventional screw press, including the background art, the contaminants containing fats and oils inflow deteriorates the dewatering performance and prevents the progress of the dehydrated water. Same as in

In other words, a means for improving water drainage by replacing a conventional circular through hole formed in the inlet cylinder of the screw press 5 with a slit-type filter hole, which is a long hole, is to have an isosceles cross section. It is formed by arranging a plurality of wedge shaped bars (5a) in a side by side to improve the filtration performance by allowing the circular filter hole to easily pass through the oil and fat components that are difficult to pass.

In addition, by placing a pressure water device (5b) having a plurality of injection nozzles (5bb) in the upper portion of the inlet to hit the inner circumferential surface of the inlet cylinder to clean the filtration tree and finely entangled in the sol state oils It helps to filter by crushing, and prevents the deterioration of dehydration performance by preventing the fat and oil from agglomerating.

3) Basic composition of the solution

The composition of the present invention, which was created based on the above main technical means, starts with the input of a substance to be treated including waste liquid containing oily waste such as manure, sewage, livestock wastewater, and the like. Wedge bar filter (2) with straight reciprocating washer (2a), liquid cyclone (3) for solid / liquid separation, screw decanter (4) for sand dehydration, and filter debris combined dewatering means And a screw press (5) having a wedge-shaped bar (5a) formed in the drain hole of the subcylinder and having a pressure water spray device (5b) on the inlet part.

In more detail, in the contaminant treatment device for filtering and dewatering and separating various solids contained in the manure, sewage, livestock wastewater, etc., including a waste liquid containing a fat or oil component, a rotary screen connected to the input device 6 ( 1) and the first tank (7) for storing the desorption liquid in the lower portion of the rotary screen (1), the filter cylinder having a filter neck having a size of about 1 mm using a wedge bar (2ba) having a wedge shape in cross section ( 2b) and a wedge bar filter (2) having a cylindrical outer circumferential reciprocating washing device (2a) which has a washing effect by a reciprocating linear motion, and injects the substance of the first tank (7) through the first pump (8). And a second tank (9) for storing the desorption liquid under the wedge bar filter (2), and the material of the second tank (9) via the second pump (10). To the liquid cyclone (3) at the bottom of the liquid cyclone (3) There is a screw decanter 4 into which the separated solid material is introduced, and there is a conveyor 16 which discharges solid materials such as sand seeds dehydrated from the screw decanter 4 to the outside. (5a) to form a slit-shaped draining hole, and the compressed portion is provided with a dewatering cylinder (5c) formed by a circular through hole (5ca) and a pressure water sprinkler (5b) in the upper portion of the holding component The screw press (5) is configured to facilitate the dehydration of, the means for combining the filtration material of the rotary screen (1) and the filtration material of the wedge bar filter (2), and the debris dewatered from the screw press (5) Means for transporting the material to the conveyor 17, the means for conveying the material of the third tank 13 in which the desorption liquid of the screw press 5 is stored to the first tank 7 using the third pump 14; , The desorption liquid and the discharged from the liquid cyclone (3) Talriaek the flow of the decanter (4) has the feature to be introduced into and then out of the device step.

4) Separate Configuration of Solution

The present invention also includes a separate configuration in which the configuration of 3) is slightly different. As described above, this is considered to be suitable for each condition because the inflow phase of the liquid waste liquid and the distribution of solids are very diverse.

In a separate configuration, first, the liquid cyclone 3 and the screw decanter 4 are omitted from the basic configuration. This can be partially applied in the case of waste liquid containing less than 1 mm of fine sand components such as fresh sludge of sewage, where more than 1 mm of sand is removed from the wedge bar filter (2) and no further sand filtration process is necessary. Applicable to

Second, the filter cylinder (2b) of the wedge bar filter (2) in the above two configurations is made of a cylindrical wedge bar (2ba) rather than a straight wedge bar (2ba). This is to fix the wedge bar (2ba) having a ring shape to several linear fixing rod (2bab), to maintain a certain gap.

For liquids with high viscosity and high surface tension, the straight wedge bar (2ba) has a good water draining effect, but the opposite phase material has a lower water concentration because the wedge bar filter has a better water draining effect. There is a characteristic that can be utilized in the waste liquid. Here, the cross section of the filtration cylinder 2b can also be made into regular polygonal shape instead of circular shape.

Third, the sprinkling liquid heating means which has the heater 5bc etc. in the pressure sprinkling apparatus 5b of the screw press 5 is included. Heated water can have a good effect on preventing clumping of fats and oils, especially in winter.

Unlike the basic configuration, the three separate configurations are worth each case depending on the situation.

Hereinafter, the operation of the contaminant treatment device of the present invention will be described.

As shown in the drawing, the present invention provides a sealed input device 6 into which an object is to be processed, and a rotary screen 1 for filtering medium / large contaminants in an inner cylinder direction from an outer circumferential surface of a cylindrical filter, The contaminants filtered by the rotary screen 1 have a first tank 7 which is stored flowing down. The first tank (8) is connected to the first pump (8) is fed to the wedge bar filter (2) the contaminants collected in the first tank (7) by the automatic operation according to the water level.

The wedge bar filter (2) is composed of a cylindrical shape having a bar filter body having a wedge-shaped cross section capable of filtering contaminants having a size of about 1 mm or more, and sprays water on the outer circumferential surface of the filtration cylinder on the upper portion thereof. A washing apparatus having a spray nozzle 2ab is installed. The washing water pipe 2aa constituting the washing device linearly reciprocates a predetermined distance.

The washing apparatus, namely reciprocating washing apparatus 2a, has a cross section smaller in stages, extends in the longitudinal direction, and is connected to the washing water pump 12 so that the pressure water of the washing water pump 12 can be introduced therein, Washing nozzles 2aa having two spray nozzles 2ab installed at regular intervals, connecting rods 2ac leading to a support shaft 2aca for linear motion at the extended end of the washing water tubes 2aa, and the connecting rods (2ac) is connected to the eccentric shaft (2af) of the reduction gear motor (2ag) and connected to the eccentric shaft (2af) and the other end is connected to the eccentric shaft (2af) and the deceleration to rotate the eccentric shaft (2af) It includes a motor (2ag).

The rotational motion of the reduction motor 2ag is converted into a linear reciprocating motion of the washing water pipe 2aa. In order to reciprocate the washing water pipe 2aa, an extension pipe 2ah having a linear motion shaft 2aha at the inlet of the washing water pipe 2aa and a flexible hose 2ai made of rubber It is then connected to the wash water pump (12).

Here, of course, a linear reciprocating cylinder (hydraulic, pneumatic, electric, etc.) may be used instead of the reduction motor (2ag). In that case the parts associated with the means for converting the rotational movements into linear reciprocating motions in this arrangement are replaced by the accessories of the cylinders.

Here, for a while, a specific embodiment to demonstrate the effect of the reciprocating washing apparatus 2a configured in the wedge bar filter 2 will be described.

The wedge bar (2ba) was assembled side by side so that the clearance of the filtration tree was 1 mm, and the inlet part was installed at a slightly higher angle by 2 degrees. The filter cylinder (2b) with an outer diameter of 700 mm and the length of the filtration effective part (2b) (throughput 100㎥ / hr), eight spray nozzles 2ab (with a spray capacity of 9.6 l / min at 2 kg / cm2 pressure) are placed at intervals of 250 mm in a 2 m long wash water pipe 2aa, on the output side of the reduction motor (2ag). The eccentric distance of the assembled eccentric shaft (2af) is 105mm, and the washing water pipe (2aa) is reciprocated at a speed of 1.5m per minute in the range of 210mm, and the washing water sprayed from one spray nozzle (2ab) is filtered through the filter cylinder (2b). If the length of contact with the tube is about 40 mm, the position is different by 16% (40 mm x 8/2 m) of the length of the filtration cylinder 2b, but the result is that the washing water always contacts.

Next, in contrast to the ability of the stationary washing device and the ability of the reciprocating washing device of the present invention, such as the background art,

First, as an example of the background art (see FIG. 7), when the conditions and the embodiment of the present invention are used together, a fixed washing water pipe 2aa of 2m length having 50 injection nozzles 2ab and 2aba at a distance of 40 mm is provided. As the pressure water of the washing water pump 12 will be introduced. In practice, however, the attachment angle of the nozzle 2ab is difficult to maintain exactly at right angles to the washing water pipe 2aa, and the contact length of the filtration cylinder 2b of the sprayed water varies slightly between the nozzles 2ab. A total of 54 nozzles (2ab, 2aba) are used with 37 mm gap between the nozzles (2ab).

Since the nozzles 2ab and 2aba also use the same ones as in the embodiment of the present invention, the flow rate at this time is 518.4 L / min (9.6 L / min × 54). It becomes 311m <3> / hr.

However, when this is compared with the throughput of 100 ㎥ / hr. Filter per hour, a large amount of washing drainage occurs more than 30% of the throughput, which may be mixed into the treated water, which may adversely affect the treatment process and burden the post-processing. Will act as. In most cases, the groundwater or discharged water is returned to the washing water and used to reduce the amount of washing water.

In consideration of this, the washing apparatus of the background art stops the spraying of the washing water until the time that can be filtered without spraying the washing water, that is, sprays the washing water intermittently at regular intervals and uses only as much washing water as necessary. In consideration of safety, the injection stop time is set slightly shorter than the experimental value.

As a result of applying the intermittent spraying method to the fixed washing water pipe (2aa), the result that the unfiltered material was not overflowed until the unsprayed idle time was 7-8 seconds, and the washing time was 1 ˜2 seconds was appropriate. In this case, when the washing water pump 12 is intermittently operated for the intermittent operation of the injection, it takes 2 to 3 seconds for the water pressure and the flow rate to become normal after the pump 12 is operated. Considering the problem of excessive initial load of the pump 12, the pump 12 is continuously operated and instead, a solenoid valve 12a is provided between the washing water pipe 2aa and the washing water pump 12. By repeating the opening and closing operation, the spraying and resting operation are repeated.

However, even in this case, the actual cleaning time is set to 3 seconds considering that it takes 1 to 2 seconds for the normal spraying by operating a constant water pressure to the farthest nozzle (2aba) when the electromagnetic valve 12a is opened and the washing water is introduced. At this time, the dwell time was 6 seconds in consideration of the safety factor, and as a result, a safe washing effect was obtained. That is, the spray water spraying time was 3/3 of the total operating time with 3 seconds spray and 6 seconds pause.

When the energy is calculated in the washing means according to the background method, the flow rate is 518.4 l / min (9.6 l / min x 54), that is, 0.5184 m3 / min, and the pressure at this time is 2 kg / cm2 First, calculate the theoretical power,

Theoretical power = 0.1635 × specific gravity × flow rate × head

         = 0.1635 × 1 × 0.5184 × 20

        ≒ 1.7 (kw). Here, considering the efficiency (less than 70%) of the wash water pump 12, the actual power is 3.75 kw and the actual energy is 3.75 kw. The motor continuously operates, but 1/3 of the injection time is full load operation. 2/3 of the time is no-load driving, and 100% of full load driving and 30% of no-load driving consumes 30% of energy.

 Energy per hour = 3.75 × 1 × 0.33 + 3.75 × 0.3 × 0.67

              ≒ 1.99 (kwh).

 Next, when calculating the energy for the configuration of the present invention, the amount of washing water is 0.0768㎥ / min (9.6ℓ / min × 8) and the head is the same 20m, so the theoretical power,

Theoretical power = 0.1635 × specific gravity × flow rate × head

         = 0.1635 × 1 × 0.0768 × 20

         ≒ 0.25 (kw), and compared with theoretical power alone, the present invention is only about 15% (0.25 / 1.7) of the background art method. However, considering the efficiency (less than 60%) of the wash water pump 12, the actual power is 0.75kw and since the motor of 0.75kw (1 horsepower) is continuously operated, the actual hourly energy requirement is 0.75kwh. (Excellent designed and designed pump, if the efficiency is over 65%, it is possible to use the actual 0.5 horsepower. In this case, the hourly energy can be 0.375kwh.) It is about 38% level compared to the conventional washing equipment ( At 0.5 horsepower, 19%). (Considering also the separate power accompanying here, the background of the washing machine is a 50A standard electronic valve 12a, and the present invention is a reduction motor (2ag) or the energy requirements of the two compared to the wash water pump 12) (100wh. Or less) to exclude from comparison.)

Next, when the amount of water used is compared, the washing device of the background art uses only one third of the total time, so the hourly flow rate is 9.6ℓ / min. × 60 × 54 × 0.33 × 1000 = 10.264 (m 3 / hr.) And the present invention is 9.6 L / min. 60 × 8 × 1000 kPa 4.6 (m 3 / hr.), The present invention is about 45% of the conventional method.

To summarize the above effects, compared to the background of the cleaning device of the present invention, the use power is about 62%, the amount of water used is about 55% is saved and the facility power is also 5 horsepower (3.7kw) and One horsepower (0.75 kw) is five times the difference, considering the production and transport costs of the wash water will be seen that the economics of the present invention is more prominent. In addition to reducing the excess drainage of the wash water by more than half, considering the effect of reducing the processing load of the post-process will be more important the importance of the effect of reducing the amount of washing water in the present invention.

As described above, in the fixed washing water pipe system such as the background art, a high-pressure washing device that requires a large amount of water is required to extract the sand squeezed in the filtration tree gap, which is not practical to use the water. In contrast to the difficult, the washing method of the present invention can be effectively applied because the water consumption is less than half thereof, the ground for the filtration of the sand by the similar size to the gap into the wedge bar filter (2) is provided. will be.

Returning to the description of the operation of the apparatus of the present invention, a second tank 9 for storing the filtrate detached from the wedge bar filter 2 is then stored under the wedge bar filter 2, and also the automatic water level operation. The second pump 10 is operated to send the filtrate to the liquid cyclone (3), and the solid components such as fine sand and seeds falling down from the liquid cyclone (3) flow back into the screw decanter (4). Dehydrated and dehydrated solids are taken out to the outside using the conveyor (16, 17).

On the other hand, the material filtered in the rotary screen (1) and the material filtered in the wedge bar filter (2) is allowed to fall down into the screw press (5) to dehydrate the contaminants containing fat and oil, and the dehydrated contaminants are dehydrated contaminant outlet ( 5i) is externally taken out to the carrying-out conveyor 17, and the desorption liquid is returned to the first tank 7 through the third pump 14 from the third tank 13 located under the screw press 5 and reprocessed. Step on the process.

And screw decanter (4) having the liquid component separated by the specific gravity difference according to the rotational centrifugal force in the above liquid cyclone (3), the solid / liquid separation action by the specific gravity difference according to the high-speed rotation and the forced discharge of the screw (4) The desorption liquid separated by the water becomes treated water and is discharged to the next process outside the apparatus.

If it described in detail with respect to the screw press (5) of a special type for the maintenance of filtration of one of the core of the present invention as follows.

The screw press 5 of the present invention takes two different means than the method of the background art. First of all, the screw press of the background art is a circular hole in which the entire through hole of the fixed cylinder is a circular hole. In the present invention, the main surface of the cylinder (filtration housing), which is the site where the filtration contaminant falls, enters a wedge type rather than a circular through hole. The upper rod 5a is laid in a longitudinal direction with a predetermined gap, and the cylinder 5c of the crimp crimping site (porous housing), which is a part thereafter, is formed by a circular through hole 5ca, that is, the transport section and the crimping site. The shape of the dehydration hole is different to suit its function, and the second is to penetrate the filtration gap of the inlet cylinder, to prevent the agglomeration of oil components, and to introduce a pressure water sprinkling device (5b) to break up the already agglomerated oil mass. It is the structure installed in the upper part of a filtration housing.

In detail, the concentric rotary screw 5d is inserted into the cylinder which is horizontally fixed, and the upper part of the cylinder main surface is cut out to be an inlet for the inflow of contaminants down, and the cylinder 5c is provided on the uncut cylinder 5c side. In the screw press 5 in which the space between the screw and the screw 5d becomes narrower toward the rear, the bottom surface of the triangle of the wedge-shaped rod 5a whose cross section is an isosceles triangular shape on the inflow side of the contaminant is constant so as to be a cylindrical inner circumferential surface. A plurality of spaces are combined to form a cylinder (filtration housing), and in a subsequent step, a plurality of circular through holes 5ca are formed on the main surface of the cylinder 5c (porous housing) with no gaps. Attached to the high pressure water pipe (5ba) will be referred to as a screw press (5) to blow the pressure water to the inner surface of the inlet cylinder (filtration housing).

The screw press of the present invention having the above configuration mainly exhibits a dehydration effect different from that of the background art in the screw press 5 for dewatering the filter contaminant containing an edible fat and oil component. .

The screw press 5 can be divided into an inlet and a compression unit as described above. The inflow part, where the filtered contaminants fall, transfers the substance to be dehydrated to the subsequent crimping part as a transport part of the contaminants, and also discharges some of the moisture introduced with the contaminants. In addition, in the inlet, although the artificial force is frictional movement between the screw (5d) and the cylinder, while the friction moves between the screw (5d) and the cylinder, a slight compressive force is applied due to the contact resistance, moisture is released from the contaminant, the primary dewatering discharged to the cylinder through the hole Action takes place.

In contrast to the general contaminants, the contaminants containing the oil and fat components contain high viscosity, surface tension, and entanglement of the oil and fat components to easily close the inlet cylinder. In the crimping part, the blocked through hole (5ca) can be easily drilled due to the strong crimping force, but in the inlet part where the large crimping force is not applied, the force enough to drill the clogged hole is not applied.

The present invention utilizes a rod as a primary means to solve this problem, the through hole of the inlet in the form of a long rectangular shape rather than a circular, slit (slit), as described for the previous effect, water dropping effect much better than the circular hole In addition, the dehydration surface is composed of a so-called wedge-shaped rod 5a, in which a cross section becomes a triangular shape so that the material once exited into the slit is not triangular and the gap is opened toward the outside.

That is, the rods of which the cross section is an isosceles triangle maintain a constant gap so that the bottom surface of the cross section is inside the cylinder, and a plurality of rods are arranged to form a semi-cylindrical hole with the upper perforated, but both ends of the wedge-shaped rods 5a are respectively Coupling to the cylindrical frame (5aa) and attach the semi-circular reinforcement frame (5ab) in a similar interval as necessary in consideration of the strength on the outer peripheral surface of the semi-cylindrical portion. The reinforcing frame 5ab is coupled to the acute end portion of the triangular cross section of the wedge shaped bar 5a. The chute 5e is attached to the opening of the upper part of the cylinder so that the filtration contaminants fall into the chute 5e.

Next, a pressure water sprinkling apparatus 5b having a plurality of spray nozzles 5bb attached to the inlet chute 5e is installed, and the injected pressure water is blown into the inlet filtration surface. This pressure water hits the filtration gap, punctures the filtration passage, and breaks up the oil component into small pieces so that it can easily escape into the gap of the wedge-shaped rod (5a), and also prevents agglomeration of the oil component that passes to the crimping part, which is not passed out. It is effective.

Spraying water where it wants to dehydrate may be seen as counter to dehydration. However, the water sprayed here is groundwater or treated water, which has almost no solid matter, penetrates the clogged filter surface, and is filtered by striking and diluting the particle component and the liquid tangled in semi-solid state (similar to gel or sol state). It helps to pass through the surface, and the sprayed water does not remain inside the cylinder and is easily released.

Next, in the case of the crimping portion, the crimping portion is prevented from clogging the through hole 5ca due to the strong compressive force due to the cross-sectional area that decreases toward the rear even when the dehydration surface is a circular through hole 5ca as described above. If the fat or oil component comes in agglomerates, it may become a lump like jelly or jelly, which may hinder the compression, and the fat or oil may be discharged as it is. Therefore, since the pressure water of the present invention hits the holding component and passes it to the compressed portion as described above, the small dispersed holding component is mixed evenly in the gap of the contaminant, so that the negative effect of the holding component described above does not appear much. This will minimize the adverse effects on dehydration.

In addition, the screw press 5 for dehydrating the oil and fat component component can exert a better performance than the conventional method even in the dehydration of the general impurities with little oil and fat component. The slit-type filter hole improves the water draining effect at the inlet part than the circular hole, and the slit gap is washed by the spray of water, and the dehydrated substances entering the compression dewatering part are mixed with each other without condensation. Because it can.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.
