Description

Technical Field

[0001] The utility model relates to the technical field of bio-drying treatment of perishable garbage, and in particular to a novel bio-drying treatment system for perishable garbage. Background Art

[0002] At present, the treatment of perishable waste is mainly based on composting and anaerobic fermentation. However, the characteristics of perishable waste in my country are high salt, high oil, high water content and a wide variety of types. The quality of the products obtained by composting is poor and cannot be directly applied as fertilizer to farmland or municipal greening, and the promotion of technology is limited. Anaerobic fermentation can produce biogas and realize resource utilization, but the remaining biogas residue and biogas liquid are more difficult to handle, and improper treatment will cause greater pollution. In order to solve the problem of perishable waste treatment, bio-drying technology has flourished in recent years. It quickly removes moisture through the heat of bio-fermentation, has a small demand for external heat energy supplement, and has a very outstanding reduction effect. Low-water content products can be used as incineration combustion materials or generate waste-derived fuel RDF, and the market application prospects are broad.

[0003] At present, biological drying treatment technology mainly adopts strip-type and drum-type treatment processes. In the strip-type treatment process, the fermented materials are stacked into strips in sequence, and the biological aerobic fermentation process is enhanced by aeration and mechanical turning to quickly remove moisture to achieve drying. However, this process occupies a large area, and the waste gas is difficult to collect and treat, and its use and promotion are relatively limited. In the drum-type treatment process, a large stirring device or a rotatable drum is installed in the middle to achieve sufficient mixing through frequent stirring, supplemented by forced ventilation and oxygen supply. Compared with the strip-type treatment process, it is more efficient, but this process is limited by stirring and mixing and structural manufacturing, and it is difficult to expand its scale. It cannot meet the current treatment needs of huge amounts of perishable garbage. Therefore, there is an urgent need for an efficient system suitable for large-scale perishable garbage drying treatment. Utility Model Content

The tower treatment device comprises a cylinder 1, a feeding device 2, a distribution device 3, a discharging system 4, and an aeration oxygen supply dehydration system 5. The feeding device 2 is arranged at the top of the cylinder 1 and is connected with the fermentation bin inside the cylinder 1. The distribution device 3 is arranged at the top of the fermentation bin just below the outlet of the feeding device 2.

An exhaust gas collection and treatment system 6 and a wastewater collection and treatment system 7 are arranged on the top and bottom of the cylinder 1 respectively. The exhaust gas collection and treatment system 6 and the wastewater collection and treatment system 7 are connected with the fermentation bin to form a dehydrated and reduced state for the materials in the fermentation bin.

[0037] In this embodiment, the processing unit of the discharging system 4 is provided with three layers, such as the a-layer discharging port located in the upper layer, the b-layer discharging port located in the middle layer, and the c-layer discharging port located in the lower layer. The layered discharging ports are arranged evenly and symmetrically around the cylinder 1 on the plane. For example, the a1 port, a2 port, a3 port, and a4 port of the a-layer discharging port are evenly and symmetrically arranged along the edge on the plane, the b1 port, b2 port, b3 port, and b4 port of the b-layer discharging port are evenly and symmetrically arranged along the edge on the plane, and the c1 port, c2 port, c3 port, and c4 port of the c-layer discharging port are evenly and symmetrically arranged along the edge on the plane. The fermentation unit is divided into fermentation areas in layers according to the arrangement of the discharge ports of each layer, with the symmetry axis of the cylinder 1 as the central axis. For example, the a1 port of the a layer discharge port corresponds to the a1 area fermentation unit, the a2 port corresponds to the a2 area fermentation unit, the a3 port corresponds to the a3 area fermentation unit, and the a4 port corresponds to the a4 area fermentation unit, dividing the processing units of the corresponding layer into four equal parts; the fermentation units in each area can be divided according to the cross-shaped support beam 41 to form a drop area between the notch of the support beam 41 and the wall of the fermentation bin. The b layer and the c layer are arranged with the a layer, which will not be elaborated here, but it should be explained that because the a layer, b layer, and c layer are designed for staggered discharge, the upper fermentation unit and the discharge port and the lower fermentation unit and the discharge port are arranged in sequence along the circumferential direction of the cylinder 1, so that, for example, the a1 port, the b1 port, and the c1 port opened in the same period, the a1 port and the b1 port and the c1 port are located at different positions on the projection plane, and at the same time, the b1 port is located at different positions on the projection plane from the c1 port and the a1 port, so as to achieve layered and staggered discharge.

[0038] That is, a1, b1, and c1 are arranged alternately on the vertical projection plane, that is, b1 corresponds to a2 on the vertical projection plane, and c1 corresponds to a3.

[0039] In this embodiment, the feeding device 2 forms a feeding port 21 at the top of the cylinder 1 , and the feeding device 2 is provided with a crushing device above the feeding port 21 .

[0040] In this embodiment, the distribution device 3 includes a grid frame 31, on which is provided an inclined guide portion for guiding the perishable garbage fragments; at the same time, the grid frame 31 is provided with a drivable rotating shaft 33 at its central top, and the rotating shaft 33 is provided with a material-dispensing blade 32, so as to push the material toward the periphery after feeding from the central feed port 21, thereby distributing the material evenly.

[0041] In this embodiment, an openable and closable baffle door 422 is provided on the discharge port 42, the bottom of the baffle door 422 is rotatably matched with the side wall of the discharge port 42 through a rotating shaft, and is equipped with a driving device for rotating it; a feeding track is provided outside the discharge port 42 for the feeding device, the feeding track includes guide rails 424 vertically arranged on both sides of the discharge port 42, and a hopper 421 is movably provided on the feeding track, and a slider 423 matching the feeding track is provided on the side of the hopper 421. When the hopper 421 moves downward, the baffle door 1 is rotated around the rotating shaft to realize the opening of the baffle door 1, and the material is discharged into the hopper 201 under the action of the stirring and discharging unit, and the fermented material is moved to the feeding device 2 under the action of the lifting device by cooperating with the lifting device, so that the fermented material is mixed with the fresh and perishable garbage entering the fermentation bin.

[0042] In this embodiment, the stirring and discharging unit includes a rotating device 431 arranged at the center of the processing unit, the rotating device 431 is located on the support beam 41, the rotating device 102 is located in the central area of ​​the fermentation bin, and a blade auger 432 is arranged obliquely upward on the rotating device 431. In order to drive the blade auger 432 to rotate around its upper rotating shaft and around the rotation center of the rotating device 431, a driving device can be respectively arranged on the rotating device 431 and the rotating shaft. Since the blades 433 of the blade auger 432 are arranged in a spiral, the material can be pushed to move toward the discharge port 42 while the blade auger 432 rotates around the rotating shaft, and the discharging starts.

[0043] In this embodiment, the aeration oxygen supply dehydration system 5 is provided with an annular pipe network 51 in the processing unit, and the annular pipe network 51 can be provided in the middle area of ​​the fermentation bin body, but it is more preferable to surround the annular pipe network 51 and arrange it closely on the inner wall of the fermentation bin body, and the annular pipe network 51 is located above the discharge port 42, and a centripetal hole is opened on the annular pipe network 51. The cylinder 1 is provided with an aeration and suction device 52 outside, and the aeration and suction device 52 has the functions of aeration and suction. The aeration and suction device 52 is connected to the annular pipe network 51 of the corresponding layer through the aeration and suction pipe 54, so as to perform aeration and exhaust gas suction of the tower treatment device. In addition, the aeration and suction device 52 is provided with an air suction pipe 53 connected to the exhaust gas collection and treatment system 6. The aeration and suction equipment 52 on each layer compresses the air and flushes it into the annular pipe network 51 through the aeration and suction pipes 54, and supplies oxygen to the fermented materials in the fermentation bin through the holes on the annular pipe network 51. The waste gas and water vapor generated during the fermentation process can also be sucked through the aeration and suction equipment 52 and successively through the annular pipe network 51, the aeration and suction pipes 54 and the suction pipes 53 to the waste gas collection and treatment system 6.

[0044] In this embodiment, the waste gas collection and treatment system 6 is connected with the waste water collection and treatment system 7 through a pipeline; the waste gas collection and treatment system 6 includes a waste gas collection unit 61 and a waste gas treatment unit 62. The waste gas collection unit 61 is provided with a negative pressure collection pipe network 611 on the top of the fermentation bin, and the waste gas treatment unit 62 is located at the outer top of the cylinder 1. The waste gas treatment unit 62 is provided with a negative pressure collection pipe 621 connected with the negative pressure collection pipe network, so that the waste gas with nearly saturated humidity generated during the fermentation of perishable garbage can be collected through the waste water collection and treatment system 7 and transported to the waste gas treatment unit 62. The waste gas treatment unit 62 can dehumidify the waste gas with nearly saturated humidity and send it to the subsequent gas purification unit, and the waste water in the dehumidification process is collected into the water treatment area of ​​the waste water collection and treatment system 7 through a pipeline. Among them, the waste gas treatment unit 602 is composed of a dehumidification, purification and high exhaust pipe, and the waste gas with high moisture content and nearly saturated humidity is discharged at a high place after dehydration and purification.

[0045] In this embodiment, for the vertical treatment system for perishable garbage, the wastewater generated during the fermentation process will flow downward and collect, so the wastewater collection and treatment system 7 is arranged at the bottom of the cylinder 1, and discharged after being treated to meet the standards. The wastewater collection and treatment system 7 is provided with a drainage body 71 inside the fermentation bin, and a permeable pipe 72 is provided inside the drainage body 71. Among them, the wastewater collection and treatment system 7 can also be provided with a capillary drainage belt 73 at the bottom of the fermentation bin, and a water collecting pipe 74 is provided below the ground at the bottom of the tower treatment device, and the water collecting pipe 74 is arranged according to the shape of the fermentation bin, and the water collecting pipe 74 is connected to the bottom drainage end of the capillary drainage belt 73. Therefore, except for part of the water generated during the fermentation process of the tower treatment device that escapes freely to the waste gas collection unit 61 at the top during the aeration process, the rest will be collected downward, resulting in a higher moisture content of the bottom material. Through the capillary siphon effect of the capillary drainage belt 73, the water flows into the water collection pipe 74 along the grooves on the capillary drainage belt 73; the water collection pipe 74 collects the water from the capillary drainage belt 73 and discharges it to the permeable pipe 72 located further below. The drainage body 71 is provided with a grid mesh at the top, and below the grid mesh are a fine-grained filler layer, a medium-coarse-grained filler layer and a gravel filler layer from top to bottom. The permeable pipe 72 in the drainage body 71 enters the permeable pipe 72 due to the capillary siphon effect, and finally reaches the gravel filler layer at the bottom to discharge the wastewater to the external water treatment area, and discharges the wastewater after it meets the standards.

[0046] In this embodiment, the processing units in the middle area (ie, layer b) are connected to the finished product area outside the discharge port 42 .

[0047] See also Figure 1-18 , during the operation of the processing system, the specific steps are as follows:

[0048] S1: Put the perishable garbage into the fermentation bin through the feeding device 2, and crush the perishable garbage into 3-5 cm materials through the crushing device, and enter the processing unit through the distribution device 3 to start fermentation;

[0049] S2: During the fermentation process, the overall stirring and mixing of the materials in the fermentation bin of the cylinder 1 is achieved by repeatedly discharging and feeding, and the fermented materials discharged from the discharge port 42 of the processing unit of each layer (layer a, layer b, layer c) enter the fermentation bin through the feeding track and the feeding device 2, and the fermented materials that do not directly fall into the processing unit and the perishable garbage are mixed during the rotation process by the material spreading blades 32 on the material spreading device 3, and the mixed materials are evenly mixed and spread on the surface of the fermented materials in the fermentation bin;

[0050] S3: When discharging, the stirring and discharging unit of the a layer stirs in the a1 zone to push the material to move to the a1 port for discharging; the stirring and discharging unit of the b layer stirs in the b1 zone to push the material to move to the b1 port for discharging; the stirring and discharging unit of the c layer stirs in the c1 zone to push the material to move to the c1 port for discharging; and because the a1 zone, b1 zone, and c1 zone are arranged alternately on the plane, the newly-input material in the a1 zone above the a1 zone, the material in the a2 zone, and the material in the b2 zone above the a1 zone, b1 zone, and c1 zone will collapse continuously due to the discharging from the lower part, so that the materials near the corresponding discharging ports a1 port, b1 port, and c1 port are fully mixed; subsequently, the a2 zone, b2 zone, and c2 zone are discharged, the a3 zone, b3 zone, and c3 zone are discharged, and the a4 zone, b4 zone, and c4 zone are discharged according to the rotation direction until the material is dried;

[0051] S4: During the discharging process, one of the discharging ports 42 of each layer of the processing unit is opened, and when the side discharging port 42 is in the discharging open state, the discharging ports 42 of the processing units of the remaining layers are staggered with the side discharging port 42 on the projection plane to discharge materials, so that the materials near the opened side discharging port 42 are fully mixed with the materials continuously falling from the upper part;

[0052] S5: During the discharging process, the aeration oxygen supply and dehydration system 5 is started, and the annular pipe network 51 in the area corresponding to the discharging position starts aeration to supply oxygen for the fermentation of nearby materials, and at the same time, the water vapor generated by the high temperature of fermentation is taken out, and at the same time, part of the heat is taken out to prevent the local temperature of the material from being too high and affecting the reproduction of the bacterial flora;

[0053] S6: The waste gas is collected by the waste gas collection unit 61 under negative pressure and enters the waste gas treatment unit 62. The waste gas with high moisture content and near saturation is dehydrated and purified and then discharged to a high place after meeting the standards. The waste water generated during the fermentation process is collected and treated by the waste water collection and treatment system 7 and then discharged after meeting the standards.

[0054] On the basis of the above content, the lower layer material (layer c) has a high water content due to the collection of wastewater, so the discharge of the middle layer (layer b) with a lower water content is used as the product. The discharge of the middle layer (layer b) is processed in depth as part of the discharge of the b1 area, and the remaining part is mixed with the discharge of the upper a1 area, the discharge of the lower c1 area and fresh perishable garbage and enters the top feeding device 2 to start a new cycle. After continuous circulation, the materials in the cylinder 1 bin are fully mixed, and a characteristic community dominated by high-temperature fermentation bacteria is gradually formed in the fermentation bin. After the fresh perishable garbage is mixed with the discharge and enters the bin, the temperature can be quickly started. The perishable garbage provides the required carbon source and nitrogen source for the reproduction of the high-temperature fermentation microbial flora in the bin, and the water produced by the fermentation and decomposition of the perishable garbage is carried by the aeration process and collected by bottom infiltration, and flows out of the fermentation system, thereby realizing the biological drying of the perishable garbage.

[0055] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
