Description

Technical Field

[0001] This utility model relates to the field of dry distillation and carbonization of fruitwood charcoal, and in particular to a device for dry distillation and carbonization of fruitwood charcoal. Background Technology

[0002] Driven by the "dual carbon" strategy and the circular economy, the fruitwood charcoal dry distillation carbonization device uses intelligent temperature control and flue gas recirculation technology to convert agricultural and forestry waste into high-calorific-value charcoal and wood vinegar as by-products, achieving efficient resource utilization and pollutant emission reduction, and has become a key piece of equipment for green energy transformation.

[0003] Fruitwood charcoal dry distillation carbonization equipment belongs to biomass energy processing equipment. Specifically, it is a continuous fruitwood charcoal dry distillation carbonization device based on a self-heating circulation system. It is suitable for the efficient carbonization treatment of biomass materials such as fruitwood branches. Most existing fruitwood charcoal dry distillation carbonization devices still adopt a single-furnace independent processing mode. Not only does the dry distillation process rely on continuous external energy input, but the thermal energy utilization efficiency is also low, resulting in high overall energy consumption. This further increases the comprehensive cost of charcoal production and restricts the economic benefits of the industry. Utility Model Content

[0004] The purpose of this invention is to provide a fruitwood charcoal dry distillation and carbonization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A fruitwood charcoal dry distillation carbonization device includes a primary carbonization combustion furnace and a primary distillation kettle installed on the primary carbonization combustion furnace. Seven sets of secondary carbonization combustion furnaces are sequentially arranged on one side of the primary carbonization combustion furnace. Each secondary carbonization combustion furnace is equipped with a secondary distillation kettle. A wood gas recycling mechanism is installed between the primary distillation kettle, the secondary distillation kettles, and the secondary carbonization combustion furnaces. The wood gas recycling mechanism is used to recycle wood gas. The wood gas recycling mechanism includes:

[0006] The recovery pipe is fixedly connected to the upper end of the primary distillation vessel and each secondary distillation vessel;

[0007] A spray condenser, which is installed on the recovery pipe;

[0008] The irregularly shaped guide tube is fixedly connected between the spray condenser and the secondary carbonization combustion furnace;

[0009] A gas-liquid separator is installed at the bottom of the spray condenser.

[0010] Both the primary carbonization combustion furnace and the secondary dry distillation kettle are fixedly connected to a flue gas outlet pipe and a feed pipe. Each flue gas outlet pipe is fixedly connected to a main flue gas outlet pipe, and each feed pipe is threaded with a sealing cap.

[0011] A conical storage tank is fixedly connected to the bottom of the gas-liquid separator.

[0014] The main exhaust pipe and the exhaust duct are manufactured as a single piece.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This fruitwood charcoal dry distillation carbonization device employs a multi-coalification combustion furnace and a multi-coal distillation kettle in a coordinated manner to produce fruitwood charcoal. A wood gas recycling mechanism is installed between the dry distillation kettle and the carbonization combustion furnace. The spray condenser in the wood gas recycling mechanism converts the mixed gases generated during carbonization in the dry distillation kettle—wood vinegar, wood tar, and water vapor—into liquid form. The wood gas, which cannot be liquefied under normal pressure, is introduced into the secondary carbonization combustion furnace through a special-shaped guide pipe for combustion, thereby heating the secondary dry distillation kettle. The secondary carbonization combustion furnaces operate in series. The wood gas recycling mechanism can effectively introduce the wood gas generated during carbonization in the dry distillation kettle into the secondary carbonization combustion furnace, achieving the goal of reducing energy consumption and improving thermal energy utilization, thereby reducing the production cost of fruitwood charcoal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] This utility model provides, for example Figure 1 - Figure 3 The illustrated fruitwood charcoal dry distillation carbonization device includes a primary carbonization combustion furnace 1 and a primary distillation kettle 2 installed on the primary carbonization combustion furnace 1. The primary carbonization combustion furnace 1 serves as the core initial heat source for the entire device, providing the heat required for carbonization to the primary distillation kettle 2 and initiating the entire dry distillation carbonization process. When the device starts operating, fuel is added to and ignited in the primary carbonization combustion furnace 1, causing its internal temperature to gradually rise. The generated heat is transferred to the primary distillation kettle 2, providing initial energy for the dry distillation of the fruitwood raw material. A hinged rotating sealing door 11 on its side wall facilitates maintenance, fuel addition, or slag removal operations when needed. The primary distillation kettle 2 holds the fruitwood raw material, which undergoes a dry distillation carbonization reaction at high temperature, converting the fruitwood into charcoal. Simultaneously, a mixture of gases such as wood gas, wood vinegar, wood tar, and water vapor is generated. The processed fruitwood raw material is loaded into the primary distillation kettle 2 through the feed pipe 22, and the sealing cap 221 is tightened to ensure airtightness. As heat from the primary carbonization combustion furnace 1 is transferred in, the fruitwood raw material undergoes a series of chemical reactions within the dry distillation kettle, gradually transforming into charcoal while simultaneously generating various mixed gases. A hinged discharge rotary door 21 on its side wall allows the charcoal to be removed after the dry distillation process is complete.

[0023] Seven sets of secondary carbonization combustion furnaces 4 are sequentially arranged on one side of the primary carbonization combustion furnace 1. The secondary carbonization combustion furnaces 4 receive and burn the wood gas introduced by the wood gas recycling mechanism 5, providing heat to the secondary distillation kettle 41, thus realizing a multi-stage series carbonization process and improving thermal energy utilization. Each secondary carbonization combustion furnace 4 is equipped with a secondary distillation kettle 41. The wood gas generated from the primary distillation kettle 2 is processed by the wood gas recycling mechanism 5 and then introduced into the secondary carbonization combustion furnace 4 through the shaped guide pipe 53. The wood gas is burned here, and the heat generated is transferred to the secondary distillation kettle 41. The secondary distillation kettle 41 performs carbonization on the fruitwood raw materials inside. The device has seven sets of secondary carbonization combustion furnaces 4 arranged sequentially, operating in series. The heat and residual gas generated by combustion provide some energy for the next furnace. Similarly, a rotating sealing door 11 is hinged to the side wall of the secondary carbonization furnace 4 for easy operation and maintenance. In conjunction with the secondary carbonization furnace 4, the secondary distillation kettle 41, under the heat provided by the secondary carbonization furnace 4, carbonizes the fruitwood raw materials to produce charcoal. A wood gas recycling mechanism 5 is installed between the primary distillation kettle 2, the secondary distillation kettle 41, and the secondary carbonization furnace 4. The wood gas recycling mechanism 5 is used to recycle the wood gas generated during the distillation process, converting liquefiable components into liquid for storage, and introducing non-liquefiable wood gas into the secondary carbonization furnace 4 for combustion, thereby improving thermal energy utilization and reducing energy consumption. The wood gas recycling mechanism 5 includes:

[0024] The recovery pipe 51 is fixedly connected to the upper end of the primary distillation vessel 2 and each secondary distillation vessel 41. The function of the recovery pipe 51 is to extract the mixed gas generated in the distillation vessel, including wood gas, wood vinegar, wood tar and water vapor.

[0025] The spray condenser 52 is installed on the recovery pipe 51. It converts the wood vinegar, wood tar and water vapor in the mixed gas into liquid by spray cooling. When the mixed gas enters the spray condenser 52 through the recovery pipe 51, the sprayed coolant cools and condenses the liquefiable components into liquid.

[0026] The irregularly shaped guide pipe 53 is fixedly connected between the spray condenser 52 and the secondary carbonization combustion furnace 4. The irregularly shaped guide pipe 53 guides the wood gas that cannot be liquefied under normal pressure after being treated by the spray condenser 52 into the secondary carbonization combustion furnace 4 for combustion. The wood gas coming out of the spray condenser 52 is accurately guided into the secondary carbonization combustion furnace 4 through the irregularly shaped guide pipe 53 to provide it with combustion energy.

[0027] The gas-liquid separator 54 is installed at the bottom of the spray condenser 52. The gas-liquid separator 54 is used to separate the gas and liquid generated during the spray condensation process. A conical storage tank 541 is fixedly connected to the bottom of the gas-liquid separator 54 for storing the separated liquid substances such as wood vinegar and wood tar.

[0028] Both the primary carbonization combustion furnace 1 and the secondary dry distillation kettle 41 are fixedly connected to a flue gas outlet pipe 31 and a feed pipe 22. Each flue gas outlet pipe 31 is fixedly connected to a main flue gas outlet pipe 3, and each feed pipe 22 is threadedly connected to a sealing cap 221. The threaded connection of the sealing cap 221 ensures the sealing of the dry distillation kettle, prevents gas leakage, and ensures that the dry distillation process is carried out in a relatively stable environment.

[0029] A conical storage tank 541 is fixedly connected to the bottom of the gas-liquid separator 54.

[0030] Both the primary carbonization combustion furnace 1 and the secondary carbonization combustion furnace 4 have hinged rotating sealing doors 11 on their side walls.

[0031] Both the primary carbonization combustion furnace 1 and the secondary dry distillation kettle 41 are hinged to the side walls of the discharge rotary door 21.

[0032] The main exhaust pipe 3 and the exhaust pipe 31 are manufactured as a single piece, resulting in a stable structure and long service life.

[0033] Example 1: Fruitwood branches cut into 60-80cm lengths are manually loaded into various retorts. The primary carbonization combustion furnace 1 serves as the heat source, providing initial heat to the primary retort 2, causing the fruitwood raw materials to begin carbonization and produce a mixed gas. The mixed gas is discharged through the recovery pipe 51 in the wood gas reuse mechanism 5. After being processed by the spray condenser 52, the wood vinegar, wood tar, and water vapor are converted into liquid and stored in the conical storage tank 541 at the bottom of the gas-liquid separator 54. The wood gas is then introduced into the secondary carbonization combustion furnace 4 through the shaped guide pipe 53 for combustion, providing heat to the secondary retort 41. The seven sets of secondary carbonization combustion furnaces 4 and secondary retort 41 are connected in series, making full use of the heat energy of the wood gas and realizing the cascade utilization of heat. This design effectively reduces energy consumption and improves the heat utilization rate, thereby significantly reducing the production cost of fruitwood charcoal and bringing higher economic benefits and a more sustainable development model to the fruitwood charcoal production industry.

[0034] Example 2: The flue gas outlet pipe 31 and the integrally formed flue gas outlet main pipe 3 promptly discharge flue gas, ensuring a stable environment within the device. The feed pipe 22 and sealing cover 221 facilitate the addition of raw materials and ensure sealing. The rotating sealing door 11 and the discharge rotating door 21 facilitate operation and maintenance. The flue gas outlet main pipe 3 contains a flue gas detection port, whose detection principle is mainly based on advanced sensor technology. When the flue gas passes through the detection port, multiple built-in sensors will function to accurately measure the content of relevant gases. These sensors will transmit the collected signals to the data processing system. After complex algorithm analysis and calibration, the accurate concentration data of various pollutants and components in the flue gas will be obtained. This allows for real-time and accurate monitoring of the composition and concentration of the flue gas discharged during the operation of the fruit charcoal dry distillation carbonization device, ensuring that the emitted flue gas meets the relevant national and local environmental protection standards, avoiding pollution of the atmospheric environment due to excessive emissions, and fulfilling the company's environmental responsibility.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
