Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a centralized biomass tobacco drying equipment. Background Technology

[0002] Tobacco curing is the core process of primary tobacco processing. It refers to the process of dehydrating and drying fresh tobacco leaves and carrying out physiological and biochemical transformations by controlling temperature, humidity and ventilation conditions in a special curing barn. The finished product is called raw tobacco.

[0003] When curing tobacco leaves, the leaves are evenly placed in the drying room, and hot air is introduced into the room through the air ducts. The staff raises the temperature of the drying room by introducing hot air, thereby drying the tobacco leaves. After the tobacco leaves are dried, the drying room is opened to remove the dried tobacco leaves.

[0004] However, when drying tobacco leaves in a drying room, a lot of manpower is required to regulate the temperature inside the drying room to ensure that the temperature is at the optimal drying temperature, thereby ensuring the drying quality of the tobacco leaves and reducing the drying efficiency.

[0005] In view of this, we propose a centralized biomass tobacco drying device. Utility Model Content

[0006] The purpose of this invention is to provide a centralized biomass tobacco drying device to solve the problem mentioned in the background art of reducing drying efficiency due to the large amount of manpower required for tobacco drying.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A centralized biomass tobacco drying device includes: a heating module, tobacco drying chambers, and a humidity module. The heating module is connected to multiple tobacco drying chambers and is used to heat the drying chambers to dry the tobacco leaves. The heating module provides centralized heating to multiple tobacco drying chambers, thereby ensuring the uniformity of temperature inside each chamber and ensuring consistent drying of the tobacco leaves, thus improving operational efficiency and achieving high-efficiency drying. Humidity modules are connected to each of the multiple tobacco drying chambers to regulate the humidity within the chambers. This prevents the tobacco leaves from scorching due to low humidity, while also preventing high humidity from affecting the quality and efficiency of the drying process.

[0008] Preferably, the heating module includes a wood crusher, a biomass hopper, a biomass hot air furnace, a dust removal and smoke extraction device, a variable frequency hot air blower, a temperature sensor, and a hot air control valve. The wood crusher is connected to the biomass hopper; the biomass hopper is connected to the biomass hot air furnace. The wood crusher crushes large pieces of wood and conveys the crushed wood from the biomass hopper to the biomass hot air furnace for combustion to generate heat. The biomass hot air furnace is equipped with a dust removal and smoke extraction device, which is fixedly connected to the variable frequency hot air blower. During the wood combustion process, the dust removal and smoke extraction device discharges the smoke generated during combustion, thereby ensuring that the variable frequency hot air blower can draw hot air from the biomass hot air furnace effectively. The hot air is dust-free, ensuring its purity and thus guaranteeing the quality of tobacco drying. It prevents dust from adhering to the tobacco leaves and affecting the drying process. A temperature sensor at the outlet of the variable frequency hot air blower detects the temperature of the hot air transmitted into the tobacco drying chamber, enabling temperature control. The variable frequency hot air blower is connected to multiple tobacco drying chambers via a heating network. Hot air control valves are also connected to the tobacco drying chambers via the heating network, with each valve corresponding to a specific chamber. The variable frequency hot air blower inputs hot air into the heating network. When tobacco leaves need drying, the corresponding hot air control valve in each drying chamber opens to allow hot air to enter and dry the leaves.

[0009] Preferably, the dust removal and smoke exhaust device is a bag filter and a ceramic multi-tube cyclone dust collector; The ceramic multi-tube cyclone dust collector adopts a tangential inlet spiral flow structure, with a centrifugal separation efficiency of ≥85%, capable of intercepting large particles with a diameter of ≥20μm, and withstanding temperatures above 120℃, making it suitable for high-temperature flue gas pretreatment. The bag filter uses PTFE membrane filter media with a filtration accuracy of 0.1μm and a surface filtration efficiency of ≥99.9%. Combined with a pulse-jet system, it achieves low-resistance operation, suitable for handling fine particulate matter. The synergistic treatment of multiple pollutants through the use of bag filters and ceramic multi-tube cyclone dust collectors can achieve coordinated treatment, with the outlet dust concentration potentially below 5mg / m³. 3 ‎.

[0010] Preferably, the humidity module includes a water tank, a water pump, and a water replenishment solenoid valve; the water pump is fixedly installed on the water tank; the water pump is connected to multiple tobacco drying rooms through a water supply network; the water replenishment solenoid valve is connected to the tobacco drying room through the water supply network, and each tobacco drying room corresponds to a specific water replenishment solenoid valve. When a tobacco drying room needs water replenishment, the water pump starts to draw purified water from the water tank and delivers the purified water to the water supply network. At this time, the water replenishment solenoid valve connected to the tobacco drying room opens, and purified water enters the tobacco drying room through the water replenishment solenoid valve to replenish water, increase the humidity inside the tobacco drying room, and prevent the tobacco leaves from scorching.

[0011] Preferably, the humidity module further includes a drying room dehumidification louver, which is fixedly installed with the tobacco drying room and connected to the biomass hot air furnace through a recycling pipeline. When the temperature inside the tobacco drying room is high, the dehumidification louvers of the drying room are opened, and the moisture inside the tobacco drying room is discharged through the recovery pipeline. At the same time, the heat inside the tobacco drying room is discharged simultaneously through the moisture discharge pipeline. At this time, the moisture and residual heat are discharged into the biomass hot air furnace through the recovery pipeline to complete the recovery and utilization of waste heat.

[0012] Preferably, a dry-bulb thermometer and a wet-bulb thermometer are fixedly installed inside the tobacco drying room; the dry-bulb thermometer and the wet-bulb thermometer are fixedly installed inside the tobacco drying room. Dry-bulb thermometers and wet-bulb thermometers in the tobacco drying room monitor the temperature and humidity in real time. When the dry-bulb thermometer detects that the temperature inside the tobacco drying room is insufficient, it sends an electrical signal to control the hot air control valve to open, thereby increasing the amount of hot air entering and thus raising the temperature inside the tobacco drying room. When the wet-bulb thermometer detects that the humidity inside the tobacco drying room is insufficient, it sends an electrical signal to control the water supply control valve to open, thereby increasing the amount of moisture entering and thus raising the humidity inside the tobacco drying room.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model saves labor costs by centrally supplying energy through heating modules, ensures heating efficiency and quality, makes the internal temperature of each tobacco drying room uniform, and allows each drying room to execute the tobacco curing temperature curve independently. In addition, it can recover the waste heat during the dehumidification process of the tobacco drying room, reducing the consumption of biomass fuel. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] When curing tobacco leaves, the leaves are evenly placed in the drying room, and hot air is introduced into the room through the air ducts. The staff raises the temperature of the drying room by introducing hot air, thereby drying the tobacco leaves. After the tobacco leaves are dried, the drying room is opened to remove the dried tobacco leaves.

[0018] However, when drying tobacco leaves in a drying room, a lot of manpower is required to regulate the temperature inside the drying room to ensure that the temperature is at the optimal drying temperature, thereby ensuring the drying quality of the tobacco leaves and reducing the drying efficiency.

[0019] like Figures 1 to 2 As shown, a centralized biomass tobacco drying device includes: a heating module 1, a tobacco drying chamber 2, and a humidity module 3; the heating module 1 is connected to multiple tobacco drying chambers 2, and the heating module 1 is used to heat the tobacco drying chambers 2 to dry the tobacco leaves; the multiple tobacco drying chambers 2 are respectively connected to humidity modules 3, and the humidity modules 3 are used to adjust the humidity of the tobacco drying chambers 2; Specifically, heating module 1 is connected to multiple tobacco drying chambers 2. Heating module 1 is used to heat the tobacco drying chambers 2 to dry the tobacco leaves. Heating module 1 provides centralized heating to multiple tobacco drying chambers 2, thereby ensuring the uniformity of the internal temperature of each tobacco drying chamber 2, thus ensuring the consistency of tobacco drying, improving operating efficiency, and achieving efficient drying. Humidity module 3 is connected to each of the multiple tobacco drying chambers 2. Humidity module 3 is used to regulate the humidity of the tobacco drying chamber 2, so that the humidity inside the tobacco drying chamber 2 is controlled to avoid the tobacco leaves from scorching due to low humidity, and at the same time, to avoid the quality and efficiency of tobacco drying from being affected by high humidity.

[0020] In this embodiment, the heating module 1 includes a wood crusher 11, a biomass hopper 12, a biomass hot air furnace 13, a dust removal and smoke exhaust device 14, a variable frequency hot air blower 15, a temperature sensor 16, and a hot air control valve 17. The wood crusher 11 is connected to the biomass hopper 12; the biomass hopper 12 is connected to the biomass hot air furnace 13; the biomass hot air furnace 13 is equipped with a dust removal and smoke exhaust device 14, and the biomass hot air furnace 13 is fixedly connected to the variable frequency hot air blower 15; a temperature sensor 16 is provided at the outlet of the variable frequency hot air blower 15, and the variable frequency hot air blower 15 is connected to multiple tobacco drying rooms 2 through a heating network; the hot air control valve 17 is connected to the tobacco drying room 2 through the heating network, and the hot air control valve 17 corresponds one-to-one with the tobacco drying room 2. Specifically, the wood shredder 11 is connected to the biomass hopper 12; the biomass hopper 12 is connected to the biomass hot air furnace 13. The wood shredder 11 crushes large pieces of wood and conveys the crushed wood from the biomass hopper 12 to the biomass hot air furnace 13 for combustion to generate heat. The biomass hot air furnace 13 is equipped with a dust removal and smoke exhaust device 14. The biomass hot air furnace 13 is fixedly connected to a variable frequency hot air blower 15. During the wood combustion process, the dust removal and smoke exhaust device 14 exhausts the smoke generated during combustion, thereby ensuring that the hot air drawn by the variable frequency hot air blower 15 from the biomass hot air furnace 13 does not contain dust, ensuring the purity of the hot air, and thus ensuring the quality of tobacco drying, preventing dust from adhering to the tobacco leaves and affecting the drying quality. A temperature sensor 16 is installed at the outlet of the variable frequency hot air blower 15. The temperature of the hot air transmitted to the tobacco drying room 2 is detected to control the temperature of the hot air, avoiding damage to the tobacco leaves due to high temperature or poor drying efficiency due to low temperature. The variable frequency hot air blower 15 is connected to multiple tobacco drying rooms 2 through the heating network. The hot air control valve 17 is connected to the tobacco drying room 2 through the heating network, and there is a one-to-one correspondence between the hot air control valve 17 and the tobacco drying room 2. The variable frequency hot air blower 15 inputs hot air into the heating network. When it is necessary to dry the tobacco leaves, the tobacco drying room 2 opens the hot air control valve 17 to control the hot air to enter and dry the tobacco leaves. When the temperature of a certain tobacco drying room 2 is too high or too low, the hot air control valve 17 of that drying room can be controlled to control the amount of hot air entering, thereby realizing the temperature regulation of a single tobacco drying room 2. At the same time, the automatic feeding and unloading reduces manual operation and improves work efficiency.

[0021] The wood shredder 11 is a mechanical device used to process raw materials such as wood and branches into wood chips or pellets. It crushes wood into sawdust, granules or flakes through impact, shearing and grinding, thereby improving wood utilization and reducing environmental pollution. The biomass hopper 12 is a special equipment for storing, screening and conveying biomass fuel. The biomass hopper 12 conveys the wood crushed by the wood shredder 11 to the biomass hot air furnace 13 for combustion. The biomass hot air furnace 13 feeds the wood conveyed by the biomass hopper 12 into the combustion chamber, where the wood is gasified and burned at high temperature to produce high-temperature flue gas or hot air. The variable frequency hot air blower 15 can automatically adjust the temperature and air volume of the hot air according to the humidity and temperature of the material, thereby achieving a more efficient drying effect. The variable frequency hot air blower 15 delivers the hot air from the biomass hot air furnace 13 to the tobacco drying room 2. The hot air control valve 17 is mainly used to cut off or regulate the flow of media such as hot air, coal gas, and flue gas in industrial high-temperature systems. The hot air control valve 17 regulates the temperature inside the tobacco drying room 2 by cutting off the hot air flow.

[0022] In this embodiment, the dust removal and smoke exhaust device 14 is a bag filter and a ceramic multi-tube cyclone dust collector; The ceramic multi-tube cyclone dust collector adopts a tangential inlet spiral flow structure, with a centrifugal separation efficiency of ≥85%, capable of intercepting large particles with a diameter of ≥20μm, and withstanding temperatures above 120℃, making it suitable for high-temperature flue gas pretreatment. The bag filter uses PTFE membrane filter media with a filtration accuracy of 0.1μm and a surface filtration efficiency of ≥99.9%. Combined with a pulse-jet system, it achieves low-resistance operation, suitable for handling fine particulate matter. The synergistic treatment of multiple pollutants through the use of bag filters and ceramic multi-tube cyclone dust collectors can achieve coordinated treatment, with the outlet dust concentration potentially below 5mg / m³. 3 ‎.

[0023] In this embodiment, the humidity module 3 includes a water tank 31, a water pump 32, and a water replenishment solenoid valve 33; the water pump 32 is fixedly installed on the water tank 31; the water pump 32 is connected to multiple tobacco drying rooms 2 through a water supply network; the water replenishment solenoid valve 33 is connected to the tobacco drying room 2 through a water supply network, and the water replenishment solenoid valve 33 corresponds one-to-one with the tobacco drying room 2; Specifically, a water pump 32 is fixedly installed on the water tank 31; the water pump 32 is connected to multiple tobacco drying rooms 2 through the water supply network; the water replenishment solenoid valve 33 is connected to the tobacco drying room 2 through the water supply network, and the water replenishment solenoid valve 33 corresponds to each tobacco drying room 2. When a tobacco drying room 2 needs water replenishment, the water pump 32 starts to draw pure water from the water tank 31 and delivers the pure water to the water supply network. At this time, the water replenishment solenoid valve 33 connected to the tobacco drying room 2 opens, and pure water enters the tobacco drying room 2 through the water replenishment solenoid valve 33 to replenish water, increase the humidity inside the tobacco drying room 2, and prevent the tobacco leaves from scorching. The main function of the water replenishment solenoid valve 33 is to control the flow of water through electromagnetic force to ensure that water enters the tobacco drying room 2 as needed and to ensure the humidity inside the tobacco drying room 2.

[0024] In this embodiment, the humidity module 3 further includes a drying room dehumidification louver 34, which is fixedly installed with the tobacco drying room 2 and is connected to the biomass hot air furnace 13 through a recycling pipeline. Specifically, when the temperature inside the tobacco drying room 2 is high, the dehumidification louvers 34 of the drying room are opened, and the moisture inside the tobacco drying room 2 is discharged through the recovery pipeline. When the moisture is discharged, the heat inside the tobacco drying room 2 is discharged simultaneously. At this time, the moisture and residual heat are discharged into the biomass hot air furnace 13 through the recovery pipeline to complete the recovery and utilization of residual heat.

[0025] In this embodiment, a dry bulb thermometer 21 and a wet bulb thermometer 22 are fixedly installed inside the tobacco drying room 2; the dry bulb thermometer 21 and the wet bulb thermometer 22 are fixedly installed inside the tobacco drying room 2; Specifically, the dry-bulb thermometer 21 and the wet-bulb thermometer 22 of the drying room monitor the temperature and humidity inside the tobacco drying room 2 in real time. When the dry-bulb thermometer 21 detects that the temperature inside the tobacco drying room 2 is insufficient, it sends an electrical signal to control the hot air control valve 17 to open, thereby increasing the amount of hot air entering and thus increasing the internal temperature of the tobacco drying room 2. When the wet-bulb thermometer 22 detects that the humidity inside the tobacco drying room 2 is insufficient, it sends an electrical signal to control the water supply control valve to open, thereby increasing the amount of moisture entering and thus increasing the internal humidity of the tobacco drying room 2. This allows for independent control of each tobacco drying room 2, enabling each tobacco drying room 2 to execute the tobacco curing temperature curve independently.

[0026] Preferably, the number of tobacco drying rooms 2 in this utility model is only shown and does not represent the actual number of drying rooms connected to this system.
