BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet waste treatment apparatus for drying and carbonizing wet wastes, and more particularly, to a dry tube assembly provided inside a combustion furnace of a wet waste treatment apparatus.

Wet wastes refer to wastes containing moisture, such as livestock manure, livestock carcasses, food waste, sewage sludge, and process sludge. Emissions of wet wastes are increasing day by day, and means and methods for the treatment of wet wastes are being explored in a variety of ways.

For example, livestock manure is known to be a composting method that converts manure into compost, a method of liquid fertilizing by solid-liquid separation, and application of sawdust using sawdust. However, these conventional methods have problems due to their respective processing characteristics, and their diffusion and use are limited.

More specifically, the composting method is known as a windrow system and an aerated pile or static pile system. However, the field method has a disadvantage that the composting stage must be carried out with a large size of 4 ~ 5m in width and 1 ~ 2m in height, and the compaction period is long. Also, the air-fed composting method requires 5 to 6 weeks' treatment and composting period, which takes a considerable time to compost. In addition, these composting methods are also problematic due to the occurrence of leachate, the harmfulness of odor and pest, and the possibility of soil contamination during the treatment process.

In the case of the liquefaction process including the membrane separation process, sludge is inevitably generated from the livestock manure, and there is a risk that soil contamination may occur due to the difference in the degree of composting of the liquefaction. Also, in general, the liquefaction process requires a relatively large area for the treatment, and the technical difficulty required for the treatment is high, so that the operation and management difficulties are also problematic. On the other hand, application of sawdust housing is inefficient in terms of time, manpower, etc., because it requires constant replacement or recycling.

In view of the above problems, the present applicant has filed an application for an apparatus for treating wet wastes by drying and carbonizing treatment. Japanese Patent Application Laid-Open No. 10-1178449 (entitled "Waste Waste Carbonization Apparatus and Waste Waste Recycling Facility Using the Same") and Registered Patent No. 10-1579441 (entitled "Waste Waste Treatment Apparatus"). The wet waste carbonization apparatuses and the like of these patent publications heat the wet waste, dry and carbonize it, thereby enabling more efficient treatment of the wet waste while requiring only a narrow space for installation.

In particular, the wet waste treatment apparatus of Patent Publication No. 10-1579441 includes a plurality of dry / carbonized tubes (hereinafter referred to as a 'drying tube'), and the wet waste is dried and carbonized And a plurality of drying tubes are densely arranged inside the combustion furnace.

1 is a schematic view showing the arrangement of drying tubes inside a combustion furnace in the above-described wet waste processing apparatus. FIG. 1 (a) is a layout diagram shown in the specification of Japanese Patent Application Laid-Open No. 10-1579441, and FIG. 1 (b) is a drawing of a product actually implemented by the applicant on the basis thereof. 1 (a) and 1 (b) show a side view of a configuration in which a plurality of drying tubes are arranged.

Referring to FIG. 1, the combustion furnace 20 may form a predetermined space therein, and a combustor for heating the wet waste in the drying tubes 10a to 10k may be disposed below the combustion furnace 20 have. Each of the drying tubes 10a to 10k is formed to extend transversely inside the furnace 20 and connected to other adjacent drying tubes 10a to 10k to form a transport path for movement of the wet waste. The wet waste is moved along the drying pipes 10a to 10k from the upper side to the lower side of the furnace 20 in a zigzag form (alternately moving in the direction indicated by (X) or (X)).

In addition, the arrangement of the conventional drying tubes 10a to 10k is zigzag in side view as shown in Fig. That is, when viewed from the side of the combustion furnace 20, the end portions of the plurality of drying tubes 10a to 10k are arranged in a staggered fashion from the upper side to the lower side. The arrangement of the drying pipe 110 is such that the wet waste can be transported by self weight or inclination between the interconnected drying pipes 10a to 10k. In other words, the drying pipe 10a at the top will be described as an example. In order to allow the wet waste transferred to the upper end of the drying pipe 10a to be moved to the next drying pipe 10b, Is arranged at a position lower than the drying tube 10a at a predetermined position. When the wet waste is transferred to the upper end of the drying pipe 10a, it can be naturally introduced into the next drying pipe 10b by its own weight or inclination of the connecting pipe 30a.

The capacity or the number of the drying pipes disposed in the combustion furnace in the arrangement of the wet waste treatment facility or the drying pipe as described above may be a factor directly related to the waste treatment capability of the apparatus. That is, the more the drying tube is disposed in the combustion furnace, the better the waste treatment ability of the apparatus can be. In other words, by optimally arranging a plurality of drying tubes inside the furnace, the waste treatment capability of the apparatus can be increased, which has the advantage of reducing the size or installation space of the apparatus in comparison with the same processing capacity in other respects.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It is to be understood, however, that the following examples are provided to facilitate understanding of the present invention, and the scope of the present invention is not limited to the following examples. In addition, the following embodiments are provided to explain the present invention more fully to those skilled in the art. Those skilled in the art will appreciate that those skilled in the art, Will be omitted.

According to the present embodiment, in the wet waste treatment apparatus, a drying tube assembly for transferring wet waste into the interior and drying or carbonizing the interior can be provided.

Here, wet wastes are meant to include various kinds of wastes having predetermined moisture contents such as livestock manure, livestock carcasses, food waste, sewage sludge, and process sludge.

An example of a wet waste treatment apparatus is disclosed in Japanese Patent Application No. 10-1579441 filed by the present applicant. The wet waste treatment apparatus of the above patent publication includes a plurality of drying tubes inside a combustion furnace, and the wet waste is dried or carbonized while being transferred into the drying tube.

The drying tube assembly of the present embodiment can be applied to the connection or disposition of the drying pipe in the wet waste treatment apparatus. However, if necessary, the drying tube assembly of this embodiment can be applied to other similar processing apparatuses other than the above-mentioned wet waste treatment apparatus, and the application thereof is not necessarily limited to the wet waste treatment apparatus.

2 is a schematic diagram illustrating a drying tube assembly 100 in accordance with one embodiment of the present invention.

Referring to FIG. 2, the drying tube assembly 100 of the present embodiment may include a drying tube 110.

The drying pipe 110 may be formed to extend in the transverse direction and may have a transverse inner flow path for transferring the wet waste. The wet waste may be transversely transferred along the drying tube 110. For convenience, FIG. 2 assumes the transfer direction of the wet waste from left to right.

At one end in the longitudinal direction of the drying pipe 110, an inlet 111 through which the wet waste flows into the drying pipe 110 may be provided. The inlet 111 may be provided at the front end in the conveying direction (i.e., the left end in the drawing), on the basis of the conveying direction of the wet waste. At the opposite end of the drying pipe 110, a discharge port 112 through which the wet waste is discharged to the outside of the drying pipe 110 may be provided. On the basis of the transport direction of the wet waste, the discharge port 112 may be provided at the rear end in the transport direction (i.e., the right end in the drawing). The inlet port 111 and the outlet port 112 can communicate with the inner flow path of the drying pipe 110 and can function as a passage through which the wet waste flows into and out of the drying pipe 110.

At this time, the inlet 111 and the outlet 112 may be opened in a direction perpendicular to the transport direction of the wet waste. In other words, the transfer direction of the wet waste may be formed so as to be substantially orthogonal to the direction in which the inlet 111 is opened or the direction in which the outlet 112 is opened. In the case of FIG. 2, for the wet waste transfer direction in the transverse direction (i.e., from left to right), the inlet 111 is opened upward in the drawing and the outlet 112 is opened downward, And are arranged to be orthogonal. The direction of the inlet 111 or the outlet 112 enables a more compact arrangement of the plurality of drying tubes 110 when the drying tubes 110 are connected to each other.

In this case, the direction of the discharge port 112 with respect to the inlet port 111 or the direction of the inlet port 111 with respect to the discharge port 112 may be changed as needed, and is not particularly limited. 2, the inlet 111 is opened toward the upper side and the outlet 112 is opened toward the lower side so that the inlet 111 and the outlet 112 are opened in opposite directions to each other. However, It is not. For example, the inlet port 111 and the outlet port 112 may be equally opened upward, downward, or laterally, and the inlet port 111 may be opened toward one side and the outlet port 112 may be opened toward the opposite side . The direction of the inlet port 111 and the outlet port 112 may be changed depending on the arrangement and connection state of the drying pipe 110 in the combustion furnace. In any case, it is preferable that the direction in which the inlet 111 or the outlet 112 is opened is arranged to be orthogonal to the conveying direction of the wet waste in the drying tube 110.

Although not shown, the inlet 111 may be connected to an outlet of another drying tube connected to the drying tube 110, and the outlet 112 may be connected to another drying tube connected to the drying tube 110 And may be installed to communicate with the inlet. However, if the drying tube 110 is disposed at the foremost end of the wet waste transport path, the inlet 111 of the drying tube 110 may be connected to a means for feeding the wet waste, such as a feed hopper, into the apparatus . Conversely, if the drying tube 110 is located at the end of the wet waste transfer path, the outlet 112 of the drying tube 110 is connected to means for external discharge by combustion of the wet waste, such as a discharge line .

Preferably, both ends of the drying pipe 110 are exposed to the outside of the combustion furnace in which the drying pipe 110 is installed. In this case, the drying tube 110 can be connected to another drying tube at each exposed end portion, and the connection portion is exposed to the outside by burning, so that the maintenance or repair work of the drying tube 110 can be facilitated.

In addition, the drying tube assembly 100 of this embodiment may include a transfer screw 120.

The conveying screw 120 may extend along the length of the drying pipe 110 to reach the other end of the drying pipe 110. The delivery screw 120 may be disposed inside the drying tube 110 and may be rotated about the longitudinal axis R about the drying tube 110.

The transfer screw 120 can transfer the wet waste within the drying tube 110. The transport direction of the wet waste is related to the direction of rotation of the transport screw 120. That is, when the conveying screw 120 is rotated in one direction (for example, clockwise about the axis R), the wet waste is conveyed along the drying pipe 110 in one direction (for example, from left to right) And when the conveying screw 120 is rotated in the opposite direction (e.g., counterclockwise about the axis R), the wet waste can be conveyed in the opposite direction (e.g., from right to left). Typically, the wet waste is in the form of a sludge or slurry containing a predetermined amount of water, so forced transport by the feed screw 120 is required for smooth transport.

Meanwhile, the drying tube assembly 100 of the present embodiment may include the blade 130.

The blade 130 may be disposed at one or both ends of the drying pipe 110. Alternatively, the blade 130 may be disposed adjacent to at least one of the inlet 111 and the outlet 112 provided in the drying tube 110. Preferably, the blade 130 may be disposed at one end and / or the other end of the drying tube 110, and more preferably, the blade 130 is disposed adjacent to the outlet 112 provided in the drying tube 110 . In the case of the present embodiment, the case where the blade 130 is disposed at the discharge port 112 is exemplified.

The blade 130 may have the function of disrupting the wet waste to a predetermined extent at the end of the drying tube 110. That is, when the wet waste flows into the drying pipe 110 or is conveyed to the end of the drying pipe 110, the blade 130 can crush the wet waste to a predetermined degree and transfer it to the next step.

The blade 130 may have a function of introducing the wet waste into the drying pipe 110 at the end of the drying pipe 110 or discharging the wet waste to the outside of the drying pipe 110. That is, when the blade 130 is disposed at the portion of the discharge port 112 as shown in the drawing, the blade 130 is moved by the conveyance screw 120 to the wet waste conveyed to the end (i.e., the left end) May be discharged to the outside of the drying pipe (110) through the discharge port (112). In this case, the discharged wet waste flows into another drying pipe connected to the drying pipe 110. However, although not shown, when the blade 130 is disposed at the inlet 111, or when the blade 130 is disposed at both the inlet 111 and the outlet 112, the blade 130 may be a wet waste To the outside of the drying pipe 110, as well as to introduce the wet waste into the drying pipe 110.

On the other hand, the blade 130 may be rotationally driven about an axis parallel to the direction of transport of the wet or waste in the lateral direction. Preferably, the blade 130 may share the axis R with the feed screw 120. In this case, the blade 130 may be directly coupled to the rotation center axis R of the feed screw 120, or may be axially coupled to the feed screw 120 and rotated together with the feed screw 120. This structure has an advantage that the internal configuration of the apparatus can be simplified. In addition, a structural simplification can reduce the malfunction rate and can also provide advantages in maintenance.

The blade 130 may be formed in various shapes, but it may be formed in a simplified form as much as possible in consideration of ease of manufacture, unit cost, and the like. In the present embodiment, the blade 130 is formed in a substantially rectangular plate shape, and one side is mounted on the axis R. However, it goes without saying that the shape of the blade 130 may be variously changed as needed.

One or more blades 130 may be provided, but a plurality of preferably three or more blades 130 may be radially arranged around the axis R. [ Increasing the number of blades 130 may improve the ability to break the wet waste through the blades 130. However, if the number of the blades 130 is excessively large, the movement of the wet waste may be hindered, so that the number of the blades 130 may be three to eight. In the case of this embodiment, a total of four blades 130 are arranged at an interval of about 90 degrees around the axis R as an example.

At least one of the inlet 111 and the outlet 112 of the drying tube 110 may be provided with connecting flanges 113 and 114 for connecting other drying tubes. Preferably, the connection flanges 113 and 114 may be provided at both the inlet 111 and outlet 112 sites. The connection flange 113 provided at the inlet port 111 side is referred to as an inlet connection flange 113 and the connection flange 114 provided at the outlet port 112 is referred to as an outlet connection flange 114, , Respectively. The inlet-side or outlet-side connection flanges 113 and 114 allow the plurality of drying tubes 110 to be easily connected to each other.

In addition, if necessary, the drying tube 110 may be divided into a plurality of portions. Preferably, the drying pipe 110 is divided into at least one of the one end portion including the inlet port 111 (i.e., the left end portion) and the other end portion including the discharge port 112 (i.e., the right end portion) . More preferably, the drying tube 110 is divided into three portions, one end including the inlet 111, the other end including the outlet 112, and a central connecting portion connecting the one end and the other end .

In this embodiment, the drying tube 110 is divided into three portions as described above. For convenience, the divided portion including the inlet port 111 is referred to as an 'inlet segment 110a' and the outlet port 112 Quot; discharge segment 110c ", and the central connecting portion is referred to as a " connecting segment 110b ". According to this, the drying pipe 110 can be divided into the inlet side segment 110a, the outlet side segment 110c and the connecting segment 110b. The drying tube 110 thus divided is advantageous in facilitating connection and maintenance work of the drying tube 110.

In this case, the inlet-side segment 110a and the outlet-side segment 110c may be formed similarly to each other. It should be noted that an inlet 111 may be provided in the inlet segment 110a and an outlet 112 may be provided in the outlet segment 110c and the direction of the inlet 111 or the outlet 112 may be different There are some differences only in that there is. The inlet segment 110a and the outlet segment 110c may each be fastened to the connecting segment 110b through a flange connection. Such flange connection has advantages of easy connection, but also advantageous in maintenance work after installation since it can be separated. In consideration of the connection operation or the maintenance operation, it is preferable that the inlet side segment 110a and the outlet side segment 110c are disposed outside the combustion furnace including the flange coupling portion coupled to the connecting segment 110b.

3 is a view showing the discharge side segment 110c shown in Fig. Fig. 3 (a) is a side schematic view of the discharge side segment 110c, Fig. 3 (b) is a front schematic view of the discharge side segment 110c, It is noted that this is a schematic plan view. Although not shown, it is noted that the inlet segment 110a may also be formed similar to the outlet segment 110c shown in FIG.

3, the discharge side segment 110c may have a predetermined space in which the wet waste can be moved, and a coupling flange 115 may be provided at one end toward the connection segment 110b . The coupling flange 115 may be flanged to the coupling segment 110b.

The discharge side segment 110c may be provided with the discharge port 112 and the discharge port 112 may be provided with the discharge side connection flange 114. [ The discharge side connection flange 114 can be flanged to the inlet side connection flange of another drying tube. In the discharge side segment 110c, the above-described transfer screw 120 and the blade 130 may be disposed.

Optionally, a sensor mounting hole 116 may be provided in the discharge side segment 110c. The sensor mounting hole 116 may be formed through the outer surface of one side of the discharge side segment 110c, and a temperature sensor may be inserted therein. The temperature sensor thus installed can measure the temperature inside the discharge side segment 110c or the drying pipe 110. [

In addition, the discharge side segment 110c may be provided with an air inlet 117 and an air inlet (not shown). The air inlet 117 may be formed on one side of the discharge side segment 110c and the air inlet may be formed on the opposite side of the other side of the discharge side segment 110c. 3 (c) shows that the discharge side segment 110c is viewed from the side of the air inlet 117, and the air inlet on the opposite side is not shown. The excess air can be discharged into the discharge side segment 110c or the drying pipe 110. [ Such excess air can promote drying or carbonization of the wet waste within the drying tube 110.

Although not shown, the inflow side segment 110a may be provided with an inflow port 111, and an inflow side connection flange 113 flanged to the discharge side connection flange of another drying pipe may be provided at the inflow port 111 (See FIG. 2). Similarly to the above-described discharge side segment 110c, the inlet side segment 110a may also be provided with a sensor mounting hole, an air inlet, and an air inlet.

FIG. 4 is a schematic view showing a state where a plurality of drying tube assemblies 100 shown in FIG. 2 are connected.

Referring to FIG. 4, a plurality of the drying tube assemblies 100 may be continuously connected. A plurality of interconnected drying tube assemblies 100 may form one transport path through which the wet waste is transported.

For convenience of explanation, the respective drying tube assemblies 100 shown in FIG. 4 will be referred to as a first drying tube assembly 100-1, a second drying tube assembly 100-2, and a third drying And a tube assembly 100-3. The respective constitutions of the first to third drying tube assemblies 100-1, 100-2 and 100-3 are also referred to as 'first, second and third'.

According to the above description, the first drying tube assembly 100-1 has the first discharge port 112-1 at the rear end (i.e., the right end) in the conveying direction and has a conveying direction in the first direction (i.e., May be provided. The first outlet 112-1 of the first drying tube assembly 100-1 may be connected to the second inlet 111-2 of the second drying tube assembly 100-2. The second drying tube assembly 100-2 has a second direction opposite to the first direction (i.e., from the right to the left) and has a second outlet 112- 2 may be connected to the third inlet 111-3 of the third drying tube assembly 100-3. In addition, the third drying tube assembly 100-3 may again be configured to transport the wet waste in a first direction.

As described above, the first to third drying tube assemblies 100-1, 100-2, and 100-3 may be disposed such that their ends are mutually connected, but their transport directions are opposite to each other. Such a conveyance direction can be set through the rotation direction of each of the conveyance screws 120-1, 120-2, and 120-3. For example, the first conveying screw 120-1 and the third conveying screw 120-3 are rotationally driven in the same direction, and the second conveying screw 120-2 is rotationally driven in the opposite direction, The conveying direction of the drying tube assemblies 100-1, 100-2, and 100-3 can be set.

Accordingly, the wet waste can be transported along the first to third drying tube assemblies 100-1, 100-2, and 100-3 while alternating between the first direction and the second direction. In other words, wet wastes have approximately 'S' shaped or zigzag shaped transport paths. Such a transfer path is space-efficient and allows the maximum number of drying tubes to be arranged in the combustion furnace with a limited space.

Preferably, the first to third drying tube assemblies 100-1, 100-2, and 100-3 may be disposed parallel to each other, and each outlet and inlet port preferably excludes a pipe structure, etc., , And may be formed to directly communicate through the flange connection. This makes it possible to arrange the first to third drying tube assemblies 100-1, 100-2, and 100-3 at minimum necessary intervals, thereby increasing the density of the drying tubes in the furnace.

Meanwhile, the first to third drying tube assemblies 100-1, 100-2, and 100-3 may be vertically disposed adjacent to each other and connected or installed laterally adjacent to each other. That is, it is noted that the embodiment shown in FIG. 4 is not limited to the upper and lower arrangements of the first to third drying tube assemblies 100-1, 100-2, and 100-3, but can also be applied to the left and right arrangements. Further, some of the drying tube assemblies may be disposed vertically adjacent to each other, and some of the drying tube assemblies may be disposed laterally adjacent to each other, if necessary. 4, the first drying tube assembly 100-1 and the second drying tube assembly 100-2 are disposed vertically adjacent to each other, and the third drying tube assembly 100-3 A configuration that is disposed adjacent to the left or right side of the second drying tube assembly 100-2 may be considered. However, in such a case, the direction of the inlet or outlet needs to be properly adjusted depending on the position of the connected drying tube assembly.

FIG. 5 is a schematic view showing the connection mode of FIG. 4 as viewed from direction A of FIG. It is noted that only the connection form between the first drying tube assembly 100-1 and the second drying tube assembly 100-2 is shown for convenience.

Referring to Figure 5, the first drying tube assembly 100-1 and the second drying tube assembly 100-2 can be communicated through the first outlet 112-1 and the second inlet 111-2 And the first discharge side connection flange 114-1 and the second inlet side connection flange 113-2 can be coupled and installed. In this case, when the first blade 130-1 of the first drying tube assembly 100-1 pushes the transferred wet waste toward the first outlet 112-1, the second drying tube assembly 100-2 The wet waste is introduced into the second drying tube assembly 100-2 through the second inlet 111-2.

It is noted that the second blade 130 shown in Fig. 5 is actually at the opposite end of the first blade 130. [

Fig. 6 is a schematic view showing a modified example in which the auxiliary blade 140 is added in the connection form shown in Fig.

Referring to FIG. 6, an auxiliary blade 140 may be further added between the first and second drying tube assemblies 100-1 and 100-2, which are interconnected as required. The auxiliary blade 140 may be disposed in an inner space of a connection portion where the first outlet 112-1 and the second inlet 111-2 are communicated with each other, and the first outlet 112-1 and the second inlet 0.0 > 111-2. ≪ / RTI > In particular, such an auxiliary blade 140 is useful in the treatment of wet wastes having a relatively low water content.

The auxiliary blade 140 may be connected to the first blade 130-1 or the second blade 130-2 and rotated. For example, the auxiliary blade 140 may be connected to a shaft of the first blade 130-1 or the second blade 130-2 through a drive transmission means such as a chain, a belt, or the like, and may be rotationally driven.

FIG. 7 is a schematic view showing a plurality of dry tube assemblies 100 shown in FIG.

Referring to FIG. 7, a plurality of the drying tube assemblies 100 of the present embodiment may be installed in the combustion furnace in a connection manner as shown in FIGS. 4 and 5. In this case, the plurality of drying tube assemblies 100 are arranged vertically and horizontally to form a densified form as shown in FIG. At this time, since each of the drying tube assemblies 100 has a shape elongated by a predetermined length in the lateral direction, the compact form shown in FIG. 7 actually forms a substantially rectangular parallelepiped-like outer shell.

As described above, the drying tube assembly according to the present embodiment can be formed in such a structure that an inlet or an outlet is formed in a direction orthogonal to the transport direction of the wet waste and directly connected to another drying tube assembly. Thus, a plurality of dry tube assemblies can be closely connected at a minimum interval, whereby a larger number of drying tubes can be disposed inside the combustion furnace. This improves the processing capability of the wet waste treatment system and can contribute to reducing the installation space. In addition, the drying tube assembly according to the present embodiment can smoothly transfer wet wastes, despite the close arrangement as described above, by crushing and transporting the wet waste through the blades.
