Description

Technical Field

[0001] The utility model relates to the field of wood drying equipment, in particular to a novel energy-saving and environment-friendly wood drying equipment. Background Art

[0002] The working principle of wood drying equipment mainly relies on heat energy transfer and material flow. Drying media such as hot air or steam are in full contact with the wood, and the moisture in the wood is evaporated through heat conduction, convection and radiation to achieve the purpose of drying. Different types of wood drying equipment may use different heating methods.

[0003] The hot air from existing wood drying equipment loses some heat during the generation and transportation process, resulting in low energy utilization. Although the use of high-power fans can accelerate the circulation of hot air, it also brings additional electricity consumption, further reducing the energy efficiency of the equipment. In addition, the drying equipment is separated from the degreasing tank. The wood needs to be degreased first and then transferred to the drying room for drying. The addition of this process not only prolongs the wood processing cycle, but also increases labor and fuel costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to provide a new energy-saving and environmentally friendly wood drying equipment in view of the above technical defects of the existing wood drying equipment.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A new type of energy-saving and environmentally friendly wood drying equipment includes: a drying room for drying wood; a heating mechanism arranged in the drying room for dissipating heat in the drying room; a burner installed on one side of the drying room and connected to the heating mechanism for providing hot air to the heating mechanism; a dust collector installed on the outside of the drying room and connected to the heating mechanism for removing dust from the gas discharged by the heating mechanism; and a dust removal water tank connected to the dust collector for further removing dust from the gas.

[0007] Preferably, the new energy-saving and environmentally friendly wood drying equipment also includes: a flue gas integration tank, which is installed on one side of the drying room and connected between the heating mechanism and the burner, and is used to collect the hot air in the burner and transport it to the heating mechanism. The flue gas integration tank can effectively concentrate the hot air generated by the burner and stably transport it to the heating mechanism through the delivery pipe, thereby improving the utilization rate of the hot air and reducing heat loss.

[0008] More preferably, the fume integrated tank includes: a delivery pipe, one end of which is connected to the fume integrated tank, and the other end of which is connected to the heating mechanism.

[0009] Preferably, the novel energy-saving and environmentally friendly wood drying equipment further comprises: an induced draft fan installed outside the drying room, connected between the heating mechanism and the dust collector, for pumping the gas in the heating mechanism into the dust collector.

[0010] More preferably, the induced draft fan includes: an air inlet pipe, one end of which is connected to the induced draft fan, and the other end is connected to the air inlet of the dust collector. The induced draft fan quickly draws the gas in the heating mechanism to the dust collector through strong suction force, thereby accelerating the flow of gas and improving the dust removal efficiency.

[0011] Preferably, the new energy-saving and environmentally friendly wood drying equipment also includes: a sedimentation tank, which is connected to the dust removal water tank and is used to precipitate the water in the dust removal water tank. The sedimentation tank precipitates the water discharged from the dust removal water tank, effectively removing suspended matter and impurities in the water.

[0012] More preferably, the dust removal water tank includes: an air outlet pipe, one end of which is connected to the dust removal water tank, and the other end is connected to the air outlet of the dust collector. The dust removal water tank serves as a secondary dust removal device, which further purifies the gas through water washing, thereby improving the dust removal efficiency. At the same time, the recovered dust can be centrally processed, which saves resources and reduces pollution to the environment.

[0013] Preferably, the new energy-saving and environmentally friendly wood drying equipment further includes: a steam generator installed on the drying room, which is used to transport steam into the drying room to bring out the grease in the wood. The steam generator transports steam into the drying room, which not only helps to discharge the grease inside the wood and improve the drying quality of the wood, but also promotes the release of internal stress in the wood through the heat and moisture effect of steam.

[0014] The present invention adopts the above technical solution, and compared with the prior art, has the following technical effects:

[0015] The utility model reduces heat loss in the process of generating and transporting hot air through direct connection of the burner and the heating mechanism, and effectively collects and distributes hot air in the flue gas integrated tank, thereby significantly improving energy utilization rate. The utility model combines the drying equipment with the degreasing function, and the steam generator transports steam into the drying room, thereby achieving simultaneous degreasing of wood during the drying process. There is no need to first transfer the wood to the degreasing tank for degreasing treatment and then transfer it to the drying room for drying. The wood processing cycle is significantly shortened, and the gas is fully dusted by the dust collector and the dust removal water tank, with significant environmental protection effects.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0023] Reference Figures 1-4 A new type of energy-saving and environmentally friendly wood drying equipment mainly includes a drying room 1, a heating mechanism 2, a burner 3, a dust collector 6 and a dust removal water tank 7.

[0024] Drying room 1 is used to dry wood. As the core area of ​​the entire drying equipment, drying room 1 provides a closed and controllable environment to ensure that the wood is efficiently dried under uniform temperature and humidity conditions. This not only shortens the drying cycle, but also greatly improves the drying quality of the wood and reduces problems such as cracking and deformation caused by uneven drying.

[0025] The heating mechanism 2 is arranged in the drying room 1 and is used to dissipate heat in the drying room. The heating mechanism 2 adopts multiple rows of heating tubes, which can effectively convert the heat generated by the burner 3 into heat energy suitable for wood drying, and evenly transfer it to the wood through radiation, convection, etc., thereby ensuring the uniformity and efficiency of the drying effect and reducing energy waste.

[0026] The burner 3 is installed on one side of the drying room 1 and is connected to the heating mechanism 2 to provide hot air to the heating mechanism 2. The burner 3 is used as a heat source and adopts clean energy combustion, which not only provides a stable heat source, but also reduces environmental pollution and meets the requirements of energy conservation and environmental protection. Its efficient combustion technology ensures the continuous supply of hot air and improves the operating efficiency of the entire drying system. The heat generated by the burner 3 can be fully utilized and is not easily lost, thereby achieving the purpose of energy saving. The burner 3 adopts a biomass particle burner 3.

[0027] The dust collector 6 is installed on the outside of the drying room 1 and is connected to the heating mechanism 2. It is used to remove dust from the gas discharged by the heating mechanism 2. The dust collector 6 effectively removes dust and impurities in the gas discharged by the heating mechanism 2, reduces air pollution, and protects the environment. At the same time, it also extends the service life of subsequent equipment such as the induced draft fan 5 and the dust removal water tank 7, ensuring the cleanliness of the drying process. The dust collector 6 adopts a multi-tube cyclone dust collector 6, and can also adopt a bag dust collector 6.

[0028] The dust removal water tank 7 is connected to the dust collector 6 and is used to remove dust from the gas again. The dust removal water tank 7 serves as a secondary dust removal device, which further purifies the gas through water washing, thereby improving the dust removal efficiency. At the same time, the recovered dust can be centrally processed, which not only saves resources but also reduces pollution to the environment. Its design is also easy to maintain and clean, maintaining the long-term and efficient operation of the system.

[0029] The flue gas integrated tank 4 is installed on one side of the drying room 1 and is connected between the heating mechanism 2 and the burner 3. It is used to collect the hot air in the burner 3 and transport it to the heating mechanism 2. The flue gas integrated tank 4 includes: a delivery pipe 401, one end of which is connected to the flue gas integrated tank 4 and the other end is connected to the heating mechanism 2. The flue gas integrated tank 4 serves as the center for hot gas collection and distribution. It can effectively concentrate the hot gas generated by the burner 3 and stably transport it to the heating mechanism 2 through the delivery pipe 401, thereby improving the utilization rate of the hot gas, reducing heat loss, and enhancing the stability and efficiency of the system.

[0030] The induced draft fan 5 is installed on the outside of the drying room 1 and is connected between the heating mechanism 2 and the dust collector 6, and is used to pump the gas in the heating mechanism 2 into the dust collector 6; the induced draft fan 5 includes: an air inlet pipe 501, one end of which is connected to the induced draft fan 5, and the other end is connected to the air inlet of the dust collector 6. The induced draft fan 5 uses a strong suction force to quickly pump the gas in the heating mechanism 2 to the dust collector 6, thereby accelerating the flow of gas and improving the dust removal efficiency. At the same time, it also ensures the air circulation in the drying room 1, which helps the wood reach the ideal drying state more quickly.

[0031] The sedimentation tank 8 is connected to the dust removal water tank 7 and is used to precipitate the water in the dust removal water tank 7. The sedimentation tank 8 performs sedimentation treatment on the water discharged from the dust removal water tank 7, effectively removing suspended matter and impurities in the water, ensuring the cleanliness of the water quality, facilitating the recycling of water, and further embodying the design concept of energy saving and environmental protection.

[0032] The dust removal water tank 7 includes an air outlet pipe 701 , one end of which is connected to the dust removal water tank 7 , and the other end of which is connected to the air outlet of the dust collector 6 .

[0033] The steam generator 9 is installed on the drying room 1 and is used to transport steam into the drying room 1 to bring out the grease in the wood. The steam generator 9 transports steam into the drying room 1, which not only helps to discharge the grease inside the wood and improves the drying quality of the wood, but also promotes the release of internal stress in the wood through the heat and moisture effect of steam, reduces deformation and cracking after drying, and improves the overall quality of the wood.

[0034] During use, the burner 3 is started and biomass pellets are used as fuel for clean combustion to generate a stable heat source. The hot gas generated by the burner 3 is collected and distributed through the flue gas integration tank 4. The flue gas integration tank 4 effectively concentrates the hot gas and stably delivers it to the heating mechanism 2 through the delivery pipe 401.

[0035] The heating mechanism 2 uses multiple rows of heating tubes to effectively convert hot air into heat energy suitable for wood drying, and starts to preheat the drying room 1. The wood to be dried is placed in the drying room 1, and the door of the drying room 1 is closed to ensure a closed and controllable drying environment. The heating mechanism 2 transfers heat energy evenly to the wood through radiation, convection, etc., and the drying process begins.

[0036] The steam generator 9 simultaneously delivers steam into the drying room 1, which helps to discharge the grease inside the wood, improve the drying quality, and promote the release of internal stress in the wood. During the drying process, the induced draft fan 5 quickly draws the gas in the heating mechanism 2 into the dust collector 6 through strong suction.

[0037] The dust collector 6 performs preliminary dust removal on the gas to remove most of the dust and impurities. The dust-removed gas enters the dust removal water tank 7 for secondary dust removal. The gas is further purified by water washing to improve the dust removal efficiency, and the dust is recovered for centralized treatment.

[0038] After dust removal, the water in the dust removal water tank 7 is connected to the air outlet of the dust collector 6 through the air outlet pipe 701 to discharge the purified gas. At the same time, the water in the dust removal water tank 7 enters the sedimentation tank 8 for sedimentation treatment. The sedimentation tank 8 effectively removes suspended matter and impurities in the water, ensures the cleanliness of the water quality, and facilitates the recycling of water.

[0039] During the entire drying process, the operating status of the system is continuously monitored, including parameters such as temperature, humidity, and gas flow rate. According to the drying condition of the wood and the operating status of the system, the combustion intensity of the burner 3, the heat dissipation efficiency of the heating mechanism 2, the pumping speed of the induced draft fan 5, etc. are adjusted in a timely manner to ensure the drying effect and efficient operation of the system. When the wood reaches the ideal drying state, the burner 3 and the heating mechanism 2 are stopped, the door of the drying room 1 is opened, and the dried wood is taken out.

[0040] In summary, compared with the existing technology, it has the following beneficial effects:

[0041] Through the direct connection between the burner 3 and the heating mechanism 2, and the effective hot gas collection and distribution of the flue gas integration tank 4, the heat loss during the generation and transportation of hot air is reduced, and the energy utilization rate is significantly improved.

[0042] By combining the drying equipment with the degreasing function, the steam generator 9 delivers steam to the drying room 1, which enables the wood to be degreased during the drying process. There is no need to first transfer the wood to the degreasing tank for degreasing and then transfer it to the drying room 1 for drying, which significantly shortens the wood processing cycle.

[0043] The gas is fully dusted by the dust collector 6 and the dust removal water tank 7, and the environmental protection effect is significant.
