Description
Technical Field
[0001] This invention relates to the field of bamboo charcoal production technology, specifically a device for separating and collecting bamboo vinegar and bamboo tar. Background Technology
[0002] The mixture of bamboo vinegar and bamboo tar produced during the pyrolysis of bamboo charcoal has become a key problem restricting the resource utilization of the industry due to its complex composition characteristics and separation technology bottlenecks. Small and medium-sized enterprises in bamboo charcoal production face the core contradiction of "separation cost being higher than product value", which directly leads to the inability to effectively recycle and utilize the mixture of bamboo vinegar and bamboo tar. Traditional distillation / extraction equipment costs over 500,000 yuan per unit and requires a steam boiler and solvent recovery system, placing a huge initial investment burden on small and medium-sized enterprises. With the addition of energy consumption and labor costs, the comprehensive cost reaches over 1,000 yuan per ton. The market price of the separated bamboo vinegar and bamboo tar cannot cover the cost, leading enterprises into a "loss upon investment" dilemma. Cost pressure forces more than 70% of bamboo charcoal plants to choose direct discharge, and the concentration of organic pollutants in the mixture exceeds the water body discharge standards by hundreds of times, causing regional ecological and environmental damage. Summary of the Invention
[0003] The purpose of this invention is to provide a bamboo vinegar and bamboo tar separation and collection device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a bamboo vinegar liquid and bamboo tar fraction separation and collection device, comprising at least one reaction vessel, a tar cooling tower, a low-temperature cooling tower, a medium-temperature cooling tower, a secondary evaporation vessel, and a high-temperature cooling tower. A multi-port pipe is connected to the exhaust pipe of the reaction vessel, and the other ports of the multi-port pipe are respectively connected to the air inlets of the tar cooling tower, the low-temperature cooling tower, and the medium-temperature cooling tower through pipelines. Each pipeline is equipped with a control valve, which is used to open the pipeline to the corresponding cooling tower according to the real-time temperature of the gas discharged from the reaction vessel, so as to realize the directional condensation and collection of different fractions. The tar cooling tower is equipped with a recovery pipe on its collection tank. The other end of the recovery pipe is connected to the furnace liner inside the secondary evaporation kettle, so that the collected high-temperature bamboo vinegar containing tar can be introduced into the secondary evaporation kettle through the recovery pipe. This allows the bamboo vinegar components in the high-temperature bamboo vinegar containing tar to evaporate into a gas phase. The exhaust pipe of the secondary evaporation kettle is then connected to the high-temperature cooling tower to condense the gas phase again, ultimately separating the tar dissolved in the bamboo vinegar from the bamboo vinegar.
[0005] Furthermore, the side wall of the reactor is connected to a heating pipe, which is connected to the combustion chamber between the inner wall of the reactor and the furnace. The other end of the heating pipe extends to communicate with the interior of the secondary evaporation vessel, thereby introducing the flue gas discharged from the reactor and using the waste heat to heat the furnace inside the secondary evaporation vessel.
[0006] Furthermore, it also includes a drying chamber, in which an inlet pipe and an outlet pipe are arranged parallel to each other on opposite sides. The inlet pipe and the outlet pipe are connected in parallel by multiple heat exchange pipes to form a closed flue gas channel. The two ends of the heat exchange pipes are detachably connected to the inlet pipe and the outlet pipe through flanges, respectively. The inlet end of the inlet pipe is connected to the side wall of the secondary evaporation kettle. The high-temperature flue gas entering the secondary evaporation kettle heats the inner furnace and is then discharged into the inlet pipe. The bamboo to be dried is placed in the drying chamber, and the drying chamber is heated by the waste heat conduction of the flue gas.
[0007] Furthermore, it also includes a spray box and a purification box connected to the spray box. The output end of the main exhaust pipe is connected to a deep cooling tower for cooling and collecting residual tar in the flue gas. The exhaust end of the deep cooling tower is connected to a blower, and the spray box is connected to the output end of the blower.
[0008] Furthermore, the control valve is an electric valve and a manual valve, with the manual valve serving as a backup. A temperature sensor is integrated at the end of the exhaust pipe of the reactor. The temperature sensor is used to detect the temperature of the gas inside the pipe. Both the temperature sensor and the electric valve are electrically connected to the processor, thereby enabling the processor to dynamically analyze the temperature data, generate control commands, and drive the corresponding electric valve to open and close, so that the gas can be diverted to the target cooling tower according to temperature.
[0009] Furthermore, the outer surfaces of the secondary evaporator, heating pipe, and main air inlet pipe extending out of the drying chamber are all covered with insulating cotton.
[0010] Furthermore, it also includes a collection tank. The side wall of the collection tank of the tar cooling tower is provided with an overflow port. The recovery pipe is connected to the overflow port. The other end of the recovery pipe extends into the collection tank. A feeding pipe is provided in the collection tank. The feeding pipe is connected to the input end of the pump body. The output end of the pump body is connected to the furnace liner in the secondary evaporator through a pipeline, so as to introduce the material in the collection tank into the furnace liner of the secondary evaporator.
[0011] Furthermore, the right connection port of the multi-port pipe is connected to the exhaust pipe of the reactor, the left connection port is connected to the tar cooling tower, the top connection port is connected to the low-temperature cooling tower through the first branch pipe, the bottom connection port is connected to a U-shaped pipe, the other end of the U-shaped pipe is connected to the medium-temperature cooling tower through the second branch pipe, the control valve is installed at the connection between the U-shaped pipe and the second branch pipe, the bottom of the U-shaped pipe is connected to a straight pipe, and the other end of the straight pipe extends into the collection tank of the tar cooling tower.
[0012] Furthermore, the outlet of the high-temperature cooling tower is connected to a discharge pipe, and the outlets of the low-temperature cooling tower and the medium-temperature cooling tower are respectively connected to discharge branch pipes, the other end of which extends to communicate with the discharge pipe; the outlet of the tar cooling tower is connected to a return pipe, the other end of which extends to communicate with the combustion chamber of the reactor, so as to introduce combustible gas as fuel for utilization.
[0013] Furthermore, the exhaust pipe on the reactor is connected to the multi-port pipe at a certain angle, and the exhaust pipe is composed of a first connecting pipe, a flexible corrugated pipe, and a second connecting pipe. The two ends of the corrugated pipe are respectively provided with a fixed flange and a movable flange. The fixed end of the first connecting pipe is welded to the exhaust port of the reactor, and the free end is connected to the corrugated pipe through the movable flange to form an adjustable connection. The second connecting pipe is rigidly connected to the corrugated pipe through the fixed flange, and the other side is connected to the main pipe of the multi-port pipe.
[0014] Furthermore, the specific structures of the reactor, drying room, and tar cooling tower can be found in other documents submitted by the applicant on the same day.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention realizes an intelligent fractionation system for temperature range through a four-way pipe linkage electric valve and a multi-stage cooling tower, accurately capturing different fractions: the low-temperature section extracts light bamboo vinegar, the medium-temperature section collects medium-active bamboo vinegar, and the high-temperature section collects tar and high-temperature bamboo vinegar; and combined with a secondary evaporation kettle, the tar dissolved in the high-temperature bamboo vinegar is separated, completely solving the problem of component mixing in traditional processes. 2. This device transforms the separation process from an independent post-processing step into an integral part of the bamboo charcoal production process, replacing the traditional distillation and extraction process. This avoids solvent consumption and dependence on steam boilers, directly reducing equipment and operating costs. At the same time, it constructs a multi-stage waste heat closed loop to maximize thermal energy utilization, significantly reducing energy consumption and maintenance costs. This enables small and medium-sized enterprises to achieve full recovery of the mixture in an economically feasible way, ensuring near-zero emissions of pollutants and eradicating regional pollution caused by traditional direct discharge.

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] like Figures 1 to 6 As shown, a bamboo vinegar liquid and bamboo tar fraction separation and collection device includes multiple reaction vessels 1, tar cooling towers 2, low temperature cooling towers 3, medium temperature cooling towers 4, secondary evaporation vessels 5, and high temperature cooling towers 6 corresponding to the number of reaction vessels 1. A multi-port pipe 7 is connected to the exhaust pipe of the reaction vessel 1. The multi-port pipe is a four-way pipe. The other connection ports of the four-way pipe are respectively connected to the air inlets of the tar cooling tower 2, the low temperature cooling tower 3, and the medium temperature cooling tower 4 through pipelines. Each pipeline is equipped with a control valve 8, which is used to open the pipeline to the corresponding cooling tower according to the real-time temperature of the gas discharged from the reaction vessel 1, so as to realize the directional condensation and collection of different fractions. Circulating cooling water flows in each cooling tower. The right end of the four-way pipe is connected to the exhaust pipe of the reactor 1, and the left end is connected to the tar cooling tower 2. The top end of each four-way pipe is connected to the low temperature cooling tower 3 through the first branch pipe 23, and the bottom end is connected to a U-shaped pipe 24. The other end of each U-shaped pipe 24 is connected to the medium temperature cooling tower 4 through the second branch pipe 25. The bottom of the U-shaped pipe 24 is connected to a straight pipe 26, and the other end of the straight pipe 26 extends into the collection tank of the tar cooling tower 2. The design of the U-shaped tube 24 is intended to prevent the tar condensed in the four-way tube from dripping directly onto the electric valve of the second branch tube 25, so as to prevent the tar from solidifying and hardening at that point, which would cause the valve to fail to open and close properly. The condensate droplets in the gas in the four-way tube sink to the bottom of the U-shaped tube 24 due to gravity, and finally flow into the collection tank of the tar cooling tower 2 through the straight pipe 26 for collection.
[0020] A recovery pipe 9 is installed on the collection tank of the tar cooling tower 2. The other end of the recovery pipe 9 is connected to the furnace liner inside the secondary evaporation kettle 5, so that the collected high-temperature bamboo vinegar liquid containing tar can be introduced into the secondary evaporation kettle 5 through the recovery pipe 9, so that the bamboo vinegar liquid components in the high-temperature bamboo vinegar liquid containing tar evaporate into the gas phase. The exhaust pipe of the secondary evaporation kettle 5 is connected to the high-temperature cooling tower to condense the gas phase again, and finally separate the tar dissolved in the bamboo vinegar liquid from the bamboo vinegar liquid.
[0021] In this embodiment, a heating pipe 10 is connected to the side wall of the reactor 1. The heating pipe 10 is connected to the combustion chamber between the inner wall of the reactor 1 and the furnace liner. The other end of the heating pipe 10 extends to communicate with the interior of the secondary evaporation vessel 5, thereby introducing the flue gas discharged from the reactor 1 and using the waste heat to heat the furnace liner inside the secondary evaporation vessel 5. In this embodiment, a drying chamber 11 is also included. An inlet pipe 12 and an outlet pipe 13 are arranged parallel to each other on opposite sides inside the drying chamber 11. The inlet pipe 12 and the outlet pipe 13 are connected in parallel by multiple heat exchange pipes 14 to form a closed flue gas channel. The two ends of the heat exchange pipes 14 are detachably connected to the inlet pipe 12 and the outlet pipe 13 respectively via flanges 15. The inlet end of the inlet pipe 12 is connected to the side wall of the secondary evaporator 5. The high-temperature flue gas entering the secondary evaporator 5 heats its inner furnace chamber before being discharged into the inlet pipe 12. The outer surfaces of the secondary evaporator 5, the heating pipe 10, and the portion of the inlet pipe 12 extending out of the drying chamber 11 are all covered with insulation cotton to suppress heat loss and improve energy efficiency. The bamboo to be dried is placed inside the drying chamber 11. The medium-temperature flue gas discharged from the secondary evaporator 5 enters the inlet pipe 12 of the drying chamber 11. The flue gas releases heat into the drying chamber 11 through the parallel heat exchange pipes 14, drying the bamboo and achieving cascade utilization of waste heat.
[0022] After a period of use, tar condensate and dust will remain in each pipeline. If not cleaned in time, it will affect the airflow. At this time, the flange can be disassembled to separate the heat exchange tube 14 connection end, thereby cleaning the heat exchange tube 14. After cleaning, it can be reinstalled.
[0023] In this embodiment, a spray box 16 and a purification box 17 connected to the spray box 16 are also included. The output end of the exhaust pipe 13 is connected to a deep cooling tower 18 for cooling and collecting residual tar in the flue gas. The exhaust end of the deep cooling tower 18 is connected to a blower 19, and the spray box 16 is connected to the output end of the blower 19. After cooling, the flue gas is output from the exhaust pipe 13 to the deep cooling tower 18. The deep cooling tower 18 can condense the residual tar in the flue gas, realize the complete removal of tar in the flue gas, and ensure that no tar enters the spray box 16. Finally, the dust and pollutants in the flue gas are adsorbed by the spray box 16 and the purification box 17 and then discharged.
[0024] In this embodiment, the control valve 8 is an electric valve and a manual valve, with the manual valve serving as a backup. A temperature sensor is integrated at the end of the exhaust pipe of the reactor 1. The temperature sensor is used to detect the temperature of the gas inside the pipe. Both the temperature sensor and the electric valve are electrically connected to the processor, so that the processor can dynamically analyze the temperature data, generate control commands, and drive the corresponding electric valve to open and close, thereby realizing the gas flow to the target cooling tower according to temperature.
[0025] In this embodiment, a collection tank 20 is also included. An overflow port is provided on the side wall of the collection tank of the tar cooling tower 2. The recovery pipe 9 is connected to the overflow port. The other end of the recovery pipe 9 extends into the collection tank 20. A feeding pipe 21 is provided in the collection tank 20. The feeding pipe 21 is connected to the input end of the pump body 22. The output end of the pump body 22 is connected to the furnace liner in the secondary evaporation kettle 5 through a pipeline. The collection tank 20 is designed to facilitate workers to pour the tar collected from other locations into it for secondary evaporation.
[0026] In this embodiment, the outlet of the high-temperature cooling tower 6 is connected to a discharge pipe 27, and the outlets of the low-temperature cooling tower 3 and the medium-temperature cooling tower 4 are respectively connected to discharge branch pipes 28. The other end of the discharge branch pipe 28 extends to communicate with the discharge pipe 27 so as to collect and discharge the exhaust gas from each cooling tower in a unified manner. The outlet of the tar cooling tower 2 is connected to a return pipe 29, and the other end of the return pipe 29 extends to communicate with the combustion chamber of the reactor 1 so as to return the treated pyrolysis gas to the combustion chamber of the reactor 1 for use as fuel, forming a pyrolysis gas cycle and cutting off the natural gas to reduce energy consumption.
[0027] In this embodiment, the exhaust pipe on the reactor 1 is connected to the four-way pipe at a certain angle. The exhaust pipe consists of a first connecting pipe 30, a flexible corrugated pipe 31, and a second connecting pipe 2. The fixed end of the first connecting pipe 30 is welded to the exhaust port of the reactor 1, and the free end is connected to the corrugated pipe 31 through a rotatable flange to form an adjustable connection. The second connecting pipe 2 is rigidly connected to the corrugated pipe 31 with a fixed flange, and the other side is connected to the main pipe of the four-way pipe. The overall design of the exhaust pipe is inclined to promote the return of tar to the reactor 1 and prevent the tar from solidifying and hardening in the pipe. Because the kettle lid needs to be frequently loaded and unloaded during production to hoist bamboo or finished charcoal into and out of the kettle, the exhaust pipe needs to be frequently loaded and unloaded. The corrugated pipe 31, through axial elastic deformation, creates a temporary installation gap between the movable flange and the mating flange, which can free up enough space for bolt installation, solve the flange assembly problem under limited space, and facilitate the loading and unloading work of the staff.
[0028] The working principle of this embodiment is as follows: Because bamboo vinegar and tar have different evaporation temperatures, the temperature of the exhaust gas (room temperature - 600℃) is monitored in real time by a temperature sensor at the end of the exhaust pipe during the production of bamboo charcoal in reactor 1. The processor makes decisions based on preset thresholds. ①If the temperature is below 120℃, the processor opens the electric valve of the first branch pipe 23, and the gas enters the low temperature cooling tower 3, where it is condensed and collected as light bamboo vinegar. The light bamboo vinegar can be used for the production of disinfectant.
[0029] ② If the temperature is between 120-250℃, the processor opens the electric valve of the second branch pipe 25, and the gas enters the medium temperature cooling tower 4 through the U-shaped pipe 24. The medium-active bamboo vinegar is condensed and collected, and the medium-active bamboo vinegar can be used for the production of deodorant.
[0030] ③ If the temperature is higher than 250℃, the processor will open the electric valve of the tar cooling tower 2 passage, and the gas will directly enter the tar cooling tower 2 to condense and collect the tar and high-temperature bamboo vinegar.
[0031] When the high-temperature bamboo vinegar liquid containing dissolved tar in the collection tank of tar cooling tower 2 reaches a certain amount (most of the tar will settle in the collection tank), it enters the recovery pipe 9 from the overflow port and then flows into the collection pool 20. The staff can also actively pour the high-temperature bamboo vinegar liquid containing dissolved tar in the collection tank into the collection pool 20. Then, the pump body 22 pumps the high-temperature bamboo vinegar liquid containing dissolved tar into the furnace chamber of the secondary evaporation kettle 5. The high-temperature flue gas (400-500℃) discharged from the reactor 1 enters the heating pipe 10 and enters the heating chamber surrounding the furnace chamber inside the secondary evaporation kettle 5, transferring heat energy to the furnace chamber. Thus, the residual heat of the reactor 1 is used to heat the secondary evaporation kettle 5. After the high-temperature bamboo vinegar liquid containing dissolved tar in the furnace chamber is heated, the bamboo vinegar liquid evaporates into a gas phase. Then, the gas phase enters the high-temperature cooling tower 6 for condensation, obtaining a high-temperature bamboo vinegar liquid rich in phenols. The high-temperature bamboo vinegar liquid can be used for fertilization. Finally, the tar dissolved in the bamboo vinegar liquid is separated from the bamboo vinegar liquid.
[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
