[0011] [Figure 1] This is a schematic diagram illustrating the configuration of a waste treatment system according to one embodiment of the present invention. [Figure 2] Figures (A) to (C) are explanatory diagrams showing the arrangement of the liquid waste input section of the waste treatment equipment provided in the waste treatment system, and are explanatory diagrams of the waste treatment equipment from the side, front, and top views, respectively. [Figure 3] This is a diagram showing a partial cross-section of a waste treatment device, illustrating the state in which the liquid waste input section of the waste treatment device has been pulled out. [Figure 4] (A) and (B) are explanatory diagrams showing a plan view and a side view, respectively, of the waste liquid receiving section of the liquid waste input area. [Modes for carrying out the invention]

[0012] Next, embodiments of the present invention will be described with reference to the attached drawings to facilitate understanding of the invention. Note that parts not relevant to the description may be omitted from the illustrations.

[0013] As shown in Figure 1, a waste treatment system 10 according to one embodiment of the present invention comprises a waste treatment device 20 and a wet scrubber 40, and can treat solid waste and liquid waste. As shown in Figures 2(A) to (C), the waste treatment device 20 has a processing unit 22, a solid waste input unit 24, and a liquid waste input unit 26, and can heat and decompose the solid and liquid waste that is input. In the following explanation, the side with the front door 222 (see Figure 2(A)), which will be described later, will be referred to as the front side, and the side with the cooler 226 will be referred to as the rear side.

[0014] The processing unit 22 has a processing chamber S1 formed inside, in which the waste is heated while air is supplied from the outside.

[0015] On the front side of the processing unit 22, an opening is formed for removing the waste decomposed in the processing chamber S1, and a single-opening front door 222 for closing this opening is provided.

[0016] On the back side of the upper part of the processing unit 22, an exhaust port 224 for discharging the exhaust gas generated during the decomposition process is formed. The exhaust gas discharged from the exhaust port 224 passes through a cooler 226 for cooling the exhaust gas and is discharged from the waste treatment device 20. The cooler 226 is provided on the back side of the processing unit 22. On the side surface of the processing unit 22, a rectangular opening 228 (see FIG. 3) leading to the processing chamber S1 is formed, and a liquid waste input section 26 is inserted into this opening 228.

[0017] As shown in FIG. 2(A), the solid waste input section 24 is provided in the upper part on the front side rather than the central part in the front-rear direction of the waste treatment device 20, and solid waste is input from the outside. In addition, in FIGS. 2(B) and 2(C), the illustration of this solid waste input section 24 is omitted. The solid waste input section 24 has an outer door 242 and an inner door (not shown) located below the outer door 242, which are connected to each other by link members, and a double door is formed by these outer door 242 and inner door. The outer door 242 is a rectangular door with a longitudinal direction in the left-right direction when viewed from the front side, and can close the input port of the solid waste formed in the upper part of the processing unit 22. The outer door 242 is a single-opening door that opens via a hinge 244 having a rotation axis extending in the left-right direction, and can open upward from the closed state.

[0018] The double door composed of such an outer door 242 and an inner door operates such that when the outer door 242 opens, the inner door closes, and when the outer door 242 closes, the inner door opens due to the action of the link members. That is, when solid waste is input in the state where the outer door 242 is open, the input solid waste is received by the inner door, and when the outer door 242 closes, the solid waste received by the inner door falls into the processing chamber S1.

[0019] The liquid waste input section 26 receives liquid waste. As shown by the arrow A in FIG. 3, the liquid waste input section 26 can be pulled out and removed from the opening 228 and is detachable. The liquid waste input section 26 has a waste liquid receiver 262, a heat insulation section 264, and a contact member 266.

[0020] As shown in FIGS. 4(A) and 4(B), the waste liquid receiver 262 is a metal container with an upper opening, into which any liquid waste is input. Note that the liquid waste includes slurry waste containing solid waste. The capacity of the waste liquid receiver 262 is, for example, 15 to 30 L. As shown in FIGS. 2(A) and 2(B), the waste liquid receiver 262 is arranged above the processing chamber S1 and on the back side of the solid waste input section 24 in a side view. As shown in FIGS. 4(A) and 4(B), a connecting fitting 270a is provided outside the waste liquid receiver 262. The connecting fitting 270a is a plate-shaped member with its tip facing upward and extending in the width direction of the waste liquid receiver 262, and is arranged at a distance from the outer surface 262a of the waste liquid receiver 262. As shown in FIG. 3, the waste liquid receiver 262 is supported by a support member 272 fixed to the frame 230 constituting the processing section 22.

[0021] The heat insulation section 264 has a heat insulating material 280 and a holding frame 282, and is provided outside the waste liquid receiver 262 (the side from which the liquid waste input section 26 shown by the arrow A in FIG. 3 is pulled out). The heat insulation section 264 is arranged at the position of the opening 228 so as to fill the opening 228. The heat insulating material 280 is, for example, rock wool, and can suppress the heat generated in the processing chamber S1 from escaping outside through the liquid waste input section 26.

[0022] The holding frame 282 has a rectangular parallelepiped outer shape and can hold the heat insulating material 280. The depth dimension D1 of the retaining frame 282 is set to be greater than or equal to the thickness D2 of the frame 230 in which the opening 228 is formed. On the side of the retaining frame 282 facing the waste liquid receiver 262 (the side facing the treatment chamber S1), there is a connecting fitting 270b which can be hooked onto the connecting fitting 270a. The connecting fitting 270b is a plate-shaped member with its tip pointing downward and extending in the width direction of the retaining frame 282 and the waste liquid receiver 262, and is positioned at a distance from the surface 282a.

[0023] Therefore, the connecting part is formed by the connecting fittings 270a and 270b, and when a force is applied to this connecting part in an up-and-down direction different from the pulling direction (the direction indicated by arrow A in Figure 3), the waste liquid receiver 262 and the heat insulating part 264 are separated. However, the connecting part is not limited to being formed by the connecting fittings 270a and 270b, and may be configured so that when a force is applied in the left-right direction, the waste liquid receiver 262 and the heat insulating part 264 are separated, and furthermore, any configuration is acceptable as long as the waste liquid receiver 262 and the heat insulating part 264 can be easily attached and detached.

[0024] The contact member 266 is a rectangular plate-shaped member that is provided on the outside of the heat insulating section 264 (the side from which the liquid waste input section 26, indicated by arrow A in Figure 3, is pulled out), and contacts the side surface of the processing section 22, and can close the opening 228. The contact member 266 makes contact via a sealing material 284 provided around the entire perimeter of the edge in order to maintain airtightness of the processing chamber S1. A pair of handles 290, visible from the side, are provided on the outer surface of the contact member 266. The contact member 266 that contacts the side surface of the processing unit 22 is fixed by multiple toggle clamps 300 arranged vertically.

[0025] The wet scrubber 40 is a purification device that removes pollutants by bringing exhaust gas containing pollutants into contact with water, thereby capturing the pollutants in the water, and can purify exhaust gas discharged from the waste treatment device 20. The water used in the wet scrubber 40 is discharged as waste liquid containing contaminants and treated in the waste treatment device 20.

[0026] Next, the processing steps for solid and liquid waste by the waste treatment system 10 will be described. The solid and liquid waste are processed according to the following steps 1 to 3. However, steps 1 and 2 may be carried out in reverse order or simultaneously.

[0027] (First step) As shown in Figure 3, the liquid waste input section 26 is pulled outwards from the opening 228 by the worker. At this time, the liquid waste input section 26 only needs to be pulled out partway so that liquid waste can be put into the waste liquid receiver 262.

[0028] Subsequently, the worker pours the liquid waste into the waste liquid receptacle 262. Here, the liquid waste may be waste liquid from the wet scrubber 40 (see Figure 1), and an example of how to input the waste liquid from the wet scrubber 40 is as follows. One example of a feeding method is for an operator to first collect the waste liquid discharged from the wet scrubber 40 into a container and then pour it from that container into the waste liquid receiver 262. As a second example of the input method, the waste treatment system 10 further includes a pump (not shown) connected to the wet scrubber 40 for discharging waste liquid, and a tube (not shown) for sending the waste liquid discharged from the pump to the fluid waste input section, and the operator operates the pump to pour the waste liquid into the waste liquid receiver 262 via the tube.

[0029] When liquid waste is collected in the waste liquid receiver 262, the liquid waste input section 26 is inserted by an operator. The liquid waste input section 26 is guided by the support member 272 as it is inserted. After insertion, the contact member 266 of the liquid waste input section 26 is fixed by the toggle clamp 300.

[0030] (Second step) The worker loads solid waste into the solid waste input section 24. The loaded solid waste falls into the processing chamber S1 when the outer door 242 closes.

[0031] (Third step) After the first and second processes are completed, the burner (not shown) is ignited and air is supplied from the outside. The air flow rate is controlled.

[0032] The solid waste inside processing chamber S1 is heated and thermally decomposed in an oxygen-reduced environment. Meanwhile, the waste liquid in the waste liquid receiver 262 is heated together with the solid waste, and is thermally decomposed as the water evaporates. Furthermore, the heating temperature during disassembly is maintained at a range of 400°C or lower.

[0033] The exhaust gas generated during thermal decomposition is purified by the wet scrubber 40 before being released into the atmosphere through the chimney 50 (see Figure 1). After processing is complete, the waste, which consists of organic matter that has been thermally decomposed, is removed through the front door 222 (see Figure 2(B)). In addition, the waste accumulated in the waste liquid receptacle 262 is removed outside along with the liquid waste input section 26 as needed.

[0034] As explained above, the waste treatment system 10 or waste treatment device 20 can treat not only solid waste but also liquid waste. In particular, the waste treatment system 10 allows the waste liquid discharged from the wet scrubber 40 to be treated inside the waste treatment system 10, thus suppressing the generation of new waste that requires treatment outside the waste treatment system 10 (by means other than the waste treatment system 10).

[0035] Although embodiments of the present invention have been described above, the present invention is not limited to the above-described forms, and any changes to the conditions, etc., that do not depart from the gist of the invention are all within the scope of application of the present invention. The liquid waste that the waste treatment system 10 or waste treatment device 20 can process is not limited to the waste liquid from the wet scrubber 40, but can be any liquid waste.
