Description

Technical Field

[0001] This utility model relates to the field of solid waste and sewage treatment technology, specifically to a device for the co-processing of garbage and sewage. Background Technology

[0002] Waste treatment facilities and sewage treatment facilities are essential infrastructure to ensure the normal operation of cities. Currently, waste treatment technology and sewage treatment technology are mature and widely used. Waste is usually treated by incineration, while sewage treatment processes are mainly based on "pretreatment + biological methods + membrane treatment".

[0003] For example, Chinese patent CN219363435U discloses a high-concentration sewage treatment system for garbage stations. This system pre-treats sewage by filtering out fine impurities, then performs biological treatment to achieve the dissolution of sludge microbial cytoplasm, thereby reducing sludge volume, and finally purifies the water body through filtration.

[0004] However, wastewater treatment and waste disposal facilities occupy a large area, and there is energy waste when incinerating waste.

[0005] Based on this, the present invention designs a device for the co-processing of waste and sewage to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a device for the co-treatment of waste and sewage.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Furthermore, the sewage treatment tank is provided with an inspection hole on its side, a bottom drain port at the bottom, and a secondary steam outlet at the top.

[0012] Furthermore, a feed inlet is provided on the side of the combustion chamber of the incinerator, and a slag discharge outlet is provided at the bottom of the combustion chamber of the incinerator.

[0013] Furthermore, the dust removal mechanism includes a first dust removal component and a second dust removal component. The first dust removal component and the second dust removal component are installed inside and on the lower side of the flue. Two sets of the second dust removal component are symmetrically arranged.

[0014] Furthermore, the first dust removal component includes a dust collection box and a dust removal box. The dust collection box is fixedly installed on the lower side of the folding flue. A dust discharge port is opened on the lower side of the folding flue, and the dust removal box is inserted into the lower side of the dust collection box.

[0015] Furthermore, the second dust removal assembly includes a cleaning component and a locking component, which are installed on the flue.

[0016] Furthermore, the cleaning assembly includes an upper rotating plate, a lower rotating plate, and an outer connecting rod. A receiving groove for accommodating the upper and lower rotating plates is provided in the folding flue. The lower end of the upper rotating plate is hinged to the receiving groove, and the lower end of the lower rotating plate is hinged to the receiving groove. One end of an outer connecting rod passes through the folding flue and is fixedly connected to the lower end of the lower rotating plate. The other end of an outer connecting rod passes through the folding flue and is fixedly connected to the lower end of the upper rotating plate.

[0018] Compared with the prior art, the advantages of this utility model are as follows: 1. The flue gas generated by combustion in the combustion chamber of the incinerator flows into the folding flue through the flue gas channel; the heat of the flue gas in the folding flue exchanges heat with the water in the flue gas heat exchange box; the flue gas in the folding flue cools down, and the water in the flue gas heat exchange box evaporates; the folding flue extends the contact area between the folding flue and the water in the flue gas heat exchange box, thereby achieving more complete heat exchange; after cooling, the flue gas in the folding flue is treated by the flue gas purification device and then discharged through the exhaust stack; solid particles in the flue gas in the folding flue settle in the folding flue and fall into the ash removal mechanism for collection; thereby reducing the processing burden of the downstream flue gas purification device.

[0019] 2. The wastewater in the wastewater treatment tank undergoes heat exchange with the steam-sewage heat exchange coil, indirectly heating the wastewater and ensuring that the water in the steam-sewage heat exchange coil is not contaminated. The steam in the steam-sewage heat exchange coil is cooled, while the wastewater in the wastewater treatment tank evaporates. The evaporated water vapor in the wastewater treatment tank is discharged through the secondary steam outlet, thereby reducing the volume of wastewater. Then, the remaining wastewater and insoluble matter in the wastewater treatment tank are transported to the wastewater spray gun by a high-pressure plunger pump and discharged into the inner top of the combustion chamber of the incinerator, where it comes into full contact with the flue gas in a counter-current manner. This achieves simultaneous treatment of garbage and wastewater, reduces the floor space required for garbage and wastewater treatment, and makes full use of energy. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 A waste and sewage co-processing device includes an incinerator combustion chamber 1, a flue gas passage 2, a flue gas heat exchange box 4, a sewage treatment box 6, an ash removal mechanism 5, a flue gas purification device 31, a fan 32, and an exhaust stack 33.

[0030] The top of the combustion chamber 1 of the incinerator is fixedly connected to one end of the flue gas passage 2; a folding flue 21 is provided in the middle of the flue gas passage 2; the other end of the flue gas passage 2 is connected to the flue gas purification device 31, the blower 32 and the exhaust stack 33 in sequence through a connecting pipe; the lower side of the sewage treatment tank 6 is connected to the high-pressure plunger pump 7 through a sewage discharge pipe; the high-pressure plunger pump 7 is connected to multiple sewage spray guns 8 through a sewage discharge pipe; the nozzle of the sewage spray gun 8 is located at the inner top of the combustion chamber 1 of the incinerator; a steam sewage heat exchange coil 61 is fixedly installed inside the sewage treatment tank 6;

[0031] The folded flue 21 is fixedly installed at the bottom of the flue gas heat exchange box 4; a side water inlet 41 is provided on the side of the flue gas heat exchange box 4, and a connecting pipe 42 is fixedly installed on the top of the flue gas heat exchange box 4; the upper end of the connecting pipe 42 is provided with two outlets, one outlet of the connecting pipe 42 is set as the residual steam outlet 9, and the other outlet of the connecting pipe 42 is fixedly connected to one end of the steam-sewage heat exchange coil 61 through the connecting pipe 42; the other end of the steam-sewage heat exchange coil 61 is provided with a condensate outlet 62; a dust removal mechanism 5 is installed inside and on the lower side of the folded flue 21.

[0032] The sewage treatment tank 6 has an inspection hole 63 on its side, a bottom drain 65 at its bottom, and a secondary steam outlet 64 at its top.

[0033] The combustion chamber 1 of the incinerator is provided with a feed inlet 11 on its side and a slag discharge outlet 12 at the bottom of the combustion chamber 1.

[0034] The flue gas purification device 31 can be a bag filter, which is a commercially available and mature device in the field. The high-pressure plunger pump 7 and the sewage spray gun 8 are also commercially available and mature devices in the field.

[0035] In this embodiment, when the waste and wastewater co-processing device is working normally, solid waste is fed into the combustion chamber 1 of the incinerator through the feed inlet 11 for combustion. The flue gas generated by combustion flows through the flue gas channel 2 into the return flue 21. The heat of the flue gas in the return flue 21 exchanges heat with the water in the flue gas heat exchange box 4, cooling the flue gas in the return flue 21 and evaporating the water in the flue gas heat exchange box 4. The design of the return flue 21 extends the contact area between the return flue 21 and the water in the flue gas heat exchange box 4, thereby achieving more complete heat exchange. After being cooled, the flue gas in the return flue 21 is treated by the flue gas purification device 31 and discharged through the exhaust stack 33. The flow speed of the flue gas in the return flue 21 is accelerated by the fan 32. Solid particles in the flue gas in the return flue 21 settle in the return flue 21 and fall into the ash removal mechanism 5 for collection, thereby reducing the purification burden of the flue gas purification device 31. The water evaporated in the flue gas heat exchange box 4... Steam flows through connecting pipe 42 into the steam-sewage heat exchange coil 61 inside the sewage treatment tank 6. The steam-sewage heat exchange coil 61 exchanges heat with the sewage in the sewage treatment tank 6, indirectly heating the sewage and ensuring the water in the steam-sewage heat exchange coil 61 is not contaminated. The steam in the steam-sewage heat exchange coil 61 cools, while the sewage in the sewage treatment tank 6 evaporates. The cooled steam in the steam-sewage heat exchange coil 61 is discharged through condensate outlet 62 for reuse, and the evaporated water vapor in the sewage treatment tank 6 is discharged through secondary steam outlet 64, thereby reducing the volume of sewage. Then, the remaining sewage and insoluble matter in the sewage treatment tank 6 are transported to the sewage spray gun 8 by the high-pressure plunger pump 7, and discharged through the sewage spray gun 8 to the inner top of the combustion chamber 1 of the incinerator, where it fully contacts the flue gas in a counter-current manner. This achieves simultaneous treatment of waste and sewage, reducing the floor space required for waste and sewage treatment and maximizing energy utilization.

[0036] Example 2: In some embodiments, such as Figures 1-4 As shown, in a preferred embodiment of the present invention, the ash removal mechanism 5 includes a first ash removal component 51 and a second ash removal component 52. The first ash removal component 51 and the second ash removal component 52 are installed inside and on the lower side of the folding flue 21, and two sets of the second ash removal component 52 are symmetrically arranged.

[0037] The first dust removal component 51 includes a dust collection box 511 and a dust removal box 513. The dust collection box 511 is fixedly installed on the lower side of the folding flue 21. A dust discharge port 512 is opened on the lower side of the folding flue 21. The dust removal box 513 is inserted into the lower side of the dust collection box 511.

[0038] The second dust removal component 52 includes a cleaning component and a locking component, which are installed on the folding flue 21;

[0039] The cleaning assembly includes an upper rotating plate 522, a lower rotating plate 523, and an outer connecting rod 524. A receiving groove 521 for accommodating the upper rotating plate 522 and the lower rotating plate 523 is provided in the folding flue 21. The lower end of the upper rotating plate 522 is hinged to the receiving groove 521, and the lower end of the lower rotating plate 523 is hinged to the receiving groove 521. One end of an outer connecting rod 524 passes through the folding flue 21 and is fixedly connected to the lower end of the lower rotating plate 523. The other end of an outer connecting rod 524 passes through the folding flue 21 and is fixedly connected to the lower end of the upper rotating plate 522.

[0040] The locking assembly includes a locking block 525 and a plug rod 526. The locking block 525 is fixedly connected to the outer end of the plug rod 526. A slot is provided on the folded flue 21, and the plug rod 526 is inserted into the slot. The locking block 525 abuts against the outer connecting rod 524.

[0041] In this embodiment, when the first cleaning assembly 51 and the second cleaning assembly 52 are working normally, the outer connecting rod 524 is rotated so that the two outer connecting rods 524 are collinear and located above the insert rod 526. At this time, the upper rotating plate 522 and the lower rotating plate 523 are located in the receiving groove 521 and in contact with the inner wall of the folding flue 21. The insert rod 526 is inserted into the slot so that the locking block 525 abuts against the two outer connecting rods 524 to complete the locking. The flue gas passes through the folding flue 21. After heat exchange, the solid particles deposited in the flue gas in the folding flue 21 fall into the cleaning box 513 through the ash discharge port 512 and are collected by the cleaning box 513. After a period of time, the cleaning box 513 can be removed for cleaning. After long-term use, Some solid particles in the flue gas adhere to the upper rotating plate 522 and lower rotating plate 523 located on the inner wall of the folding flue 21. At this time, the locking block 525 and the insert rod 526 are pulled out, so that the locking block 525 is no longer in contact with the outer connecting rod 524. The outer connecting rod 524 is rotated, which drives the upper rotating plate 522 and lower rotating plate 523 to rotate in opposite directions. The ends of the upper rotating plate 522 and lower rotating plate 523 knock against each other, causing the upper rotating plate 522 and lower rotating plate 523 to vibrate. This causes the solid particles attached to the inner wall of the upper rotating plate 522 and lower rotating plate 523 to fall down and fall into the ash removal box 513 through the ash discharge port 512. This achieves the cleaning of the ash discharge port 512 and the ash removal box 513, avoiding blockage in the folding flue 21 and affecting the flow of flue gas.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
