Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment equipment, in particular to a continuous drying and carbonization device for residual sludge from brewing. Background Art

[0002] Excess sludge from brewing is the sediment produced by treating wastewater from liquor production. According to existing liquor production processes, producing 1 ton of liquor consumes approximately 60 tons of water and generates 48 tons of wastewater, of which 1-2% is converted into sludge, significantly increasing the amount of excess sludge produced. Excess sludge flocs are composed of filamentous bacteria, upon which other microorganisms and organic matter adsorb and form bridges. This structure is formed by the electrostatic attraction of anions and cations, creating a spatial network. This strong affinity for water makes dehydration difficult, resulting in high energy consumption, high costs, and low treatment efficiency when used for incineration to generate power. Furthermore, the high organic content in excess sludge makes it prone to decay and odor, potentially causing secondary pollution. Therefore, achieving harmless and volume-reducing treatment of excess sludge has become a key challenge facing liquor producers.

[0003] For the harmless and volume reduction treatment process of winemaking surplus sludge, what is urgently needed is how to dry and carbonize the winemaking surplus sludge to facilitate its subsequent use or storage, and reduce the secondary pollution to the environment caused by stacking. Therefore, the drying and carbonization treatment of winemaking surplus sludge has become one of the focus technologies studied by technicians in this field.

[0004] At present, a large number of studies on sludge drying-carbonization treatment devices have emerged in the prior art. For example, Patent No. 201720296030.0 discloses a sludge dryer and a hot air supply device for supplying dry sludge with a high moisture content into the sludge dryer; a separation device for separating the dried sludge from the sludge dryer from the hot air; and a carbonization device for carbonizing the dried sludge separated from the separation device to form a carbonide, thereby effectively treating the sludge, preventing pollution to the sludge pile environment, achieving energy conservation and environmental protection, and low operating costs.

[0005] Another example: Patent No. 202321393501.1 discloses a sludge drying and carbonization integrated machine, which includes an interconnected feeding device, a drying device, a carbonization device and a heating device. The drying and carbonization steps are combined and carried out simultaneously to improve the sludge carbonization treatment efficiency and reduce the overall treatment time.

[0006] However, the continuous drying and carbonization of sludge is still a technical problem that technicians in this field need to overcome. Therefore, the researchers of the present invention, in combination with the research on the resource utilization of residual sludge from brewing, provide an improved device structure for the continuous drying and carbonization of residual sludge from brewing, providing a new device for the harmless and reduced treatment of residual sludge from brewing.

The drying furnace 21 is provided with an exhaust gas outlet at the bottom, which is connected to the exhaust gas treatment assembly 10 via a collection pipe 12. The exhaust gas in the drying furnace 21 is discharged through the exhaust gas outlet and is treated by the exhaust gas treatment assembly 10 before being discharged into the air. The tail gas generated in the carbonization furnace 8 enters the drying furnace 21 through the feed port and the discharge port to be utilized for heat exchange, and is then discharged through the tail gas outlet for treatment.

[0033] In some embodiments, the carbonization furnace 8 is provided with an exhaust outlet at the bottom thereof, which is connected to an exhaust gas treatment assembly 10 via a collection pipe 12. This allows the exhaust gas generated by carbonization in the carbonization furnace 8 to be directly discharged through the exhaust outlet and enter the exhaust gas treatment assembly 10 for treatment and subsequent discharge.

[0034] like Figure 1-3 As shown, in some embodiments, a one-way valve 5 is provided on the blast pipe 2 between the blower 4 and the combustion chamber 1 to adjust the flow rate of gas blown into the combustion chamber 1 by the blower 4, so as to adjust the amount of heating gas in the combustion chamber 1 and ensure sufficient combustion in the combustion chamber 1.

[0035] like Figure 1-3 As shown, in some embodiments, a one-way valve 5 is provided on the gas inlet pipe 3; it is used to adjust the amount of gas fed in to match the amount of gas blown in by the blower 4 to ensure sufficient combustion in the combustion chamber 1, avoid wasting gas, and ensure the efficiency of gas heating.

[0036] like Figure 1-3As shown, in some embodiments, a one-way valve 5 is provided on the collecting pipe 12 to adjust the exhaust efficiency, thereby achieving the purpose of adjusting the temperature in the carbonizing furnace 8 and the drying furnace 21.

[0037] like Figure 1-3 As shown, in some embodiments, a blower 6 is provided on the hot air supply pipe 17, and a one-way valve 5 is provided between the blower 6 and the hot air outlet. This allows the heated gas in the combustion chamber 1 to enter the drying furnace 21 and the carbonization furnace 8 in a one-way manner, thereby preventing it from flowing back into the combustion chamber 1, resulting in high energy consumption and even causing flameout in the combustion chamber 1.

[0038] like Figure 1-3 As shown, in some embodiments, the drying furnace 21 includes a closed drying chamber and a drying chamber 23, the drying chamber 23 is cylindrical, and the drying chamber 23 runs through the left and right ends of the closed drying chamber; the feed end 26 is provided at the left end of the drying chamber 23, and the discharge end is provided at the right end of the drying chamber 23; the drying gas pipe 22 and the exhaust gas outlet are provided on the closed furnace cavity; a rotating part 25 is provided at the contact position between the drying chamber 23 and the closed drying chamber, and the rotating part 25 can make the drying chamber 23 rotate relative to the closed furnace cavity. The drying chamber 23 is constructed in a drum shape, so that after the residual sludge from brewing enters the drying chamber 23 through the feed end 26, it can be turned over as the cylindrical drying chamber 23 rolls, and can continuously move toward the discharge end during the turning process, realizing drying while turning, thereby improving the drying efficiency, and realizing a continuous feeding and discharging process from the feed end to the discharge end, thereby realizing continuous drying, which helps to improve the harmless and reduced treatment efficiency of the residual sludge from brewing and ensure the treatment effect.

[0039] like Figure 1-3As shown, in some embodiments, the carbonization furnace 8 includes a closed carbonization chamber and a carbonization chamber 13. The carbonization chamber 13 is cylindrical and runs through the left and right ends of the closed carbonization chamber. A feed port is provided at the top of the carbonization chamber 13 near the left end, and a discharge port is provided at the right end of the carbonization chamber 13. The closed carbonization chamber is provided with the heat increasing pipe 16 and the exhaust gas outlet. A carbonization heat inlet is provided at the top of the carbonization chamber 13 near the right end, and the carbonization heat inlet is connected to the hot gas outlet via the carbonization gas pipe 7. A spiral shaft 14 is provided in the carbonization chamber 13, and a connecting shaft 18 is connected to the left end of the spiral shaft 14. The connecting shaft 18 extends from the left end of the carbonization chamber 13 and is connected to a belt pulley 19. The spiral shaft 14 can transport the material entering from the feed port to the discharge port. After the feed port and the discharge end are connected, the residual brewing sludge discharged from the drying chamber 23 after drying continuously enters the carbonization chamber 13, and is continuously pushed toward the discharge port through the spiral shaft 14 in the carbonization chamber 13 to realize continuous feeding and carbonization, thereby achieving the purpose of continuous drying and carbonization of the residual brewing sludge and improving the drying and carbonization treatment efficiency of the residual brewing sludge.

[0040] like Figure 1-3 As shown, in some embodiments, a one-way valve 5 is provided on the carbonization gas pipe 7 to adjust the amount of heating gas entering the carbonization chamber 13 on the carbonization furnace, thereby adjusting the temperature in the carbonization chamber.

[0041] like Figure 1-3 As shown, in some embodiments, a one-way valve 5 is provided on the heat increasing pipe 16 to adjust the amount of heating gas entering the closed carbonization chamber to achieve the purpose of regulating the temperature outside the carbonization chamber 13 for heat preservation.

[0042] like Figure 1-3 As shown, in some embodiments, a one-way valve 5 is provided on the drying gas pipe 22 to adjust the amount of heating gas entering the closed drying chamber, thereby achieving the purpose of adjusting the drying temperature in the drying chamber 23.

[0043] On the basis of the technical solution formed by combining the above-mentioned embodiments, those skilled in the art may also use a PLC control panel to control the flow of heated gas in the combustion chamber 1, that is, to use the PLC control panel to control the opening and closing degree of the one-way valve 5, thereby realizing the control of the flow rate of the heating gas, thereby controlling the temperature in the drying furnace 21 and the carbonization furnace 8, and realizing the purpose of intelligently adjusting and controlling the drying temperature and the carbonization temperature.

[0044] like Figure 3As shown, in some embodiments, a temperature sensor 29 is provided in the enclosed drying chamber; and / or a temperature sensor 29 is provided in the enclosed carbonization chamber. The temperature sensor 29 is used to monitor the drying temperature and the carbonization temperature, thereby adjusting the temperature as needed. In some embodiments, a PLC control panel is used. By connecting the temperature sensor 29 to the PLC control panel and simultaneously connecting the one-way valve 5 to the PLC control panel, the temperature monitored by the temperature sensor 29 can be fed back to the PLC control panel. The PLC control panel then controls the opening and closing degree of the one-way valve 5, thereby adjusting and controlling the temperature in the drying furnace 21 and the carbonization furnace 8, thereby achieving intelligent temperature control.

[0045] like Figure 2 As shown, in some embodiments, a manhole 28 is provided in the enclosed drying chamber and / or the enclosed carbonization chamber. This facilitates shutdown and maintenance of the internal structure of the enclosed drying chamber and / or the enclosed carbonization chamber, and also facilitates monitoring and observation of the internal conditions, thereby ensuring stable operation of the drying and carbonization processes.

[0046] In addition to the above technical solutions, the present invention focuses on the connection between the carbonization furnace 8 and the drying furnace 21 and the improvement of the structure in the drying furnace 21, so that the drying can be continuously fed and discharged, so that the dried winemaking residual sludge can continuously enter the carbonization furnace 8 for carbonization, thereby improving the drying and carbonization efficiency of the winemaking residual sludge. Figure 1-3 As shown, in some embodiments, the discharge end is provided with a connecting cover 20, and the drying chamber 23 is able to freely rotate relative to the connecting cover 20; the connecting cover 20 is provided with a connecting pipe 15, and the connecting pipe 15 is connected to the feed port. This allows the drying chamber 23 to freely rotate at the discharge end, ensuring that the residual brewing sludge in the drying chamber 23 can be gradually slid toward the discharge end by the rotation of the drying chamber 23, thereby improving the continuity of the feeding and drying processes.

[0047] like Figure 1-3 As shown, in some embodiments, a toothed belt 27 is provided on the outer wall of the drying chamber 23. The external gear can be used to cause the gear and the toothed belt 27 to rotate the drying chamber 23, thereby turning over the residual brewing sludge entering the drying chamber 23.

[0048] like Figure 1-3As shown, in some embodiments, the drying chamber 23 is provided with a plurality of guide plates 24, and the guide plates 24 are capable of directing the flow of the brewing waste sludge entering from the feed end 26 toward the discharge end. This prevents the brewing waste sludge from clogging the feed end during the rotation of the drying chamber 23. Instead, the brewing waste sludge is continuously turned and slid toward the discharge end as the drying chamber 23 rotates, guided by the guide plates 24. This achieves continuous feeding and sliding drying, thereby improving drying efficiency.

[0049] In certain embodiments, the exhaust outlet is connected to the interior of the drying chamber 23, so that the exhaust gas generated during the drying and carbonization processes can be collected by the collection pipe 12 and then enter the exhaust gas treatment assembly 10 for treatment. Furthermore, an exhaust pipe 11 is provided on the exhaust gas treatment assembly 10, so that the exhaust gas treated by the exhaust gas treatment assembly 10 is discharged through the exhaust pipe 11. When the exhaust outlet is connected to the interior of the drying chamber 23, the exhaust outlet can be connected to the feed end 26 and an exhaust fan can be used to draw air to the exhaust outlet; the exhaust outlet can also be connected to the discharge end and an exhaust fan can be used to draw air to the exhaust outlet; or the exhaust outlet can be connected to the connection cover 20. This allows the exhaust gas generated during the drying and carbonization processes to be collected and treated, thereby preventing environmental pollution caused by the drying and carbonization processes.

[0050] In some embodiments, the exhaust port on the carbonization furnace 8 is connected to the combustion chamber 1, so that the dry distillation gas generated during the carbonization process can be used to provide heat in the combustion chamber 1. In some embodiments, the exhaust port on the carbonization furnace 8 is connected to the combustion chamber 1 through the exhaust gas treatment component 10, so that the dry distillation gas generated during the carbonization process is treated by the exhaust gas treatment component 10 and then sent to the combustion chamber 1 for combustion and heat supply.

[0051] Other matters not covered by the present invention may be realized by conventional technical means with reference to the prior art or common knowledge known to those skilled in the art, for example, the treatment method within the exhaust gas treatment component 10 .
