Description

Technical Field

[0001] The invention relates to the technical field of graphite-methanol production, in particular to a graphite-methanol production vaporizer with a heat energy recovery function and a production method. Background Art

[0002] With the continuous growth of industrial production and energy demand, efficient vaporization of materials has become an important research direction in the industrial field. Traditional vaporizers have certain limitations in terms of energy utilization, material handling efficiency and environmental friendliness. In order to meet the requirements of modern industry for high efficiency, energy saving and environmental protection, the research and development and improvement of new vaporizers are particularly necessary. The future development trend is to integrate efficient material handling systems, advanced control mechanisms and energy recovery devices to build an efficient and cyclic vaporization system to improve production efficiency and resource utilization.

[0003] At present, vaporizers on the market usually adopt a simple structural design, mainly consisting of a heater, a basic material conveying system and a simple control device. Some equipment may be equipped with temperature and pressure sensors for basic process monitoring. However, in terms of material screening, shearing, recovery and waste heat utilization, the functions of traditional vaporizers are relatively simple. They usually lack sophisticated material screening and shearing mechanisms, and cannot effectively separate and process materials of different particle sizes. In addition, the lack of waste heat recovery devices leads to low energy utilization and failure to achieve the recovery and reuse of incompletely vaporized materials.

[0004] Traditional vaporizers have obvious deficiencies in material processing efficiency and energy utilization. Due to the lack of effective screening mechanisms and shearing components, the particle size distribution of the material cannot be accurately controlled, resulting in low vaporization efficiency and waste of resources. The simplification of the control mechanism makes it impossible to accurately adjust the temperature, pressure and flow rate during the vaporization process, affecting product quality and production stability. At the same time, the lack of a waste heat recovery mechanism fails to utilize the high-temperature waste heat generated during the vaporization process, resulting in energy waste and environmental burden. Since there is no effective recovery and recycling mechanism for materials that are not fully vaporized, the utilization rate of resources is further reduced. Therefore, those skilled in the art provide a graphite methanol vaporizer with heat recovery function and a production method. Summary of the invention

[0005] The object of the present invention is to provide a graphite methanol vaporizer with heat energy recovery function and a production method to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: The vaporizer comprises a recovery mechanism, a screening mechanism, a collecting mechanism and a control mechanism. The screening mechanism is connected to the recovery mechanism, the collecting mechanism is connected to the screening mechanism, the control mechanism is fastened to the collecting mechanism, and the recovery mechanism is connected to the collecting mechanism.

[0007] By adopting the above technical solution, first, the screening mechanism is connected to the recovery mechanism to screen the incoming materials, and the particles that do not meet the requirements are returned through the recovery mechanism for reprocessing. The collecting mechanism is connected to the screening mechanism to collect the screened materials of different particle sizes for different temperature and pressure controls. The control mechanism is tightly connected to the collecting mechanism to monitor and adjust the parameters in the collection process in real time to ensure the stability of the vaporization process. The recovery mechanism is also connected to the collecting mechanism, and can recover the incompletely vaporized materials and re-enter the reaction. Through the synergistic effect of these parts, the vaporizer realizes efficient vaporization of materials, improves work efficiency, optimizes resource utilization, and achieves the expected effect.

[0008] Furthermore, the screening mechanism includes a screening cylinder, a multi-stage spiral wind cylinder, a fan, a shearing assembly, a gear assembly, and a screening motor. The screening motor and the screening cylinder are tightly connected, the screening motor and the gear assembly are transmission-connected, the gear assembly and the multi-stage spiral wind cylinder are transmission-connected, the multi-stage spiral wind cylinder and the screening cylinder are rotationally connected, the shearing assembly and the screening cylinder are tightly connected, the fan and the multi-stage spiral wind cylinder are tightly connected, the multi-stage spiral wind cylinder is provided with a number of multi-stage spiral wind cylinders, a number of multi-stage spiral wind cylinders are provided with spiral grooves, a number of multi-stage spiral wind cylinders are provided with step-by-step screening holes, a number of multi-stage spiral wind cylinders descend in a step-by-step manner, a number of step-by-step screening holes are provided, and the apertures of the step-by-step screening holes decrease step by step from the outside to the inside in the horizontal direction.

[0009] By adopting the above technical solution, the screening motor is tightly connected to the screening cylinder to provide a power source, and drives the multi-stage spiral wind drum to rotate through the gear assembly connected by transmission. The multi-stage spiral wind drum is rotatably connected to the screening cylinder, and is provided with spiral grooves and step-by-step screening holes, and these wind drums are arranged in a step-by-step manner, and the aperture decreases step by step from the outside to the inside. The fan is tightly connected to the multi-stage spiral wind drum to enhance the fluidity of the material. The shearing assembly is fixed on the screening cylinder to shear the incoming material. In the work process, the screening motor drives the multi-stage spiral wind drum to rotate, and the material is screened by the step-by-step screening holes under the guidance of the spiral groove, and the airflow provided by the fan accelerates the material to pass through the sieve hole. The shearing assembly shears larger particles to promote their passage through the sieve hole. Through this working principle, efficient separation and screening of materials of different particle sizes are achieved, the screening accuracy and efficiency are improved, and the effective processing of materials and the smooth progress of subsequent processes are ensured.

[0010] Furthermore, the shearing assembly includes a shearing shell, a first shearing plate, a second shearing plate, a shearing motor, a first shearing bead, and a second shearing bead. The shearing motor and the second shearing plate are fastened together, the second shearing plate and the shearing shell are fastened together, the shearing motor and the first shearing plate are transmission-connected, the first shearing bead and the first shearing plate are rotationally connected, the second shearing bead and the second shearing plate are rotationally connected, the first shearing bead and the second shearing bead abut against each other, an upper shearing hole is provided on the first shearing plate, and a lower shearing hole is provided on the second shearing plate. The upper shearing holes and the lower shearing holes are in a right-angled trapezoidal vertical section, the upper shearing holes and the lower shearing holes are staggered, and the upper shearing holes and the lower shearing holes become smaller as the screening aperture decreases step by step.

[0011] By adopting the above technical solution, the shearing assembly is composed of a shearing shell, a first shearing plate, a second shearing plate, a shearing motor, a first shearing bead and a second shearing bead. The shearing motor is tightly connected to the second shearing plate to drive the first shearing plate to rotate. The first shearing plate is connected to the shearing motor through transmission and is rotatably connected to the first shearing bead; the second shearing plate is fixed on the shearing shell and is rotatably connected to the second shearing bead. The first shearing bead and the second shearing bead abut against each other to form a shearing interface. An upper shearing hole is provided on the first shearing plate, and a lower shearing hole is provided on the second shearing plate. The vertical sections of the two shearing holes are right-angled trapezoids and are arranged alternately. The sizes of the upper shearing holes and the lower shearing holes decrease as the aperture of the screening is reduced step by step. In the working process, the material enters from the entrance of the shearing assembly and passes through the shearing area between the first shearing plate and the second shearing plate. The shearing motor drives the first shearing plate to rotate, and the first shearing bead abuts against the second shearing bead to shear the material. Since the upper shearing holes and the lower shearing holes are arranged alternately and the cross-section is a right-angled trapezoid, the material is effectively sheared and crushed when passing through the shearing holes. As the screening aperture decreases step by step, the size of the shearing hole also decreases accordingly, ensuring that the material is sheared to the required fineness. This working principle ensures that the material is fully sheared and refined in the shearing assembly, improving the efficiency of subsequent screening. The close coordination of each part realizes the efficient operation of the equipment and achieves the purpose of improving material processing effect and production efficiency.

The transmission gear column is connected to the multi-stage spiral wind tube so that it can rotate and work. The multi-stage spiral wind tube is provided with rotating teeth and grooves, and the transmission gear column is engaged with these rotating toothed gears to ensure efficient power transmission and synchronous rotation. In the working process, after the screening motor is started, the transmission gear is driven to rotate through the transmission belt. The rotation of the transmission gear is transmitted to the multi-stage spiral wind tube through the transmission gear column. Since the transmission gear column is engaged with the rotating toothed gear on the wind tube, the multi-stage spiral wind tube can rotate stably and effectively. This working principle ensures the efficient transmission of power from the motor to the wind tube. The effect achieved is that the power transmission system of the entire screening mechanism runs smoothly, reduces energy loss, and improves screening efficiency. The close fit of each part makes the equipment reliable, easy to maintain, and extends the service life of the equipment.

[0014] Furthermore, the collecting mechanism includes a preheating component, a liquid collecting tank, a liquid level sensor, a reflux pump, and a graphite vaporization chamber.

The graphite vaporization chamber is provided with a spiral heat exchange pipe, a multi-layer diverter plate assembly, a fluid agitator, an anti-clogging filter, an inlet pipe, and a catalyst pipe. The spiral heat exchange pipe is used to increase the contact area of ​​the heating medium. The multi-layer diverter plate assembly is used to promote uniform vaporization. The fluid agitator promotes uniform heating of the liquid. The anti-clogging filter prevents impurities from clogging the pipe. The liquid is filtered by the anti-clogging filter and then sent back to the graphite vaporization chamber. The spiral heat exchange pipe is coiled along the axial direction of the vaporization chamber. The inner wall of the spiral heat exchange pipe is provided with a micro-texture structure. The fluid agitator is installed at the bottom center of the graphite vaporization chamber. The anti-clogging filter is installed at the front end of the inlet pipe. The catalyst pipe is connected to the graphite vaporization chamber.

[0015] By adopting the above technical scheme, the collection mechanism includes a preheating component, a liquid collecting tank, a liquid level sensor, a reflux pump and a graphite vaporization chamber. The liquid collecting tank is used to collect unvaporized methanol liquid. The liquid level sensor is installed in the liquid collecting tank to monitor the liquid level in real time to ensure that the liquid is recovered in time. The reflux pump is connected to the graphite vaporization chamber to send the unvaporized methanol in the liquid collecting tank back to the graphite vaporization chamber through the inlet pipe. The front end of the inlet pipe is provided with an anti-clogging filter to prevent impurities from clogging the pipe. The inside of the graphite vaporization chamber is provided with a spiral heat exchange pipe, a multi-layer splitter plate assembly, a fluid agitator and a catalyst pipe. The spiral heat exchange pipe is coiled along the axial direction of the vaporization chamber, and the inner wall is provided with a micro-texture structure, which increases the contact area of ​​the heating medium and improves the heat transfer efficiency. The multi-layer splitter plate assembly promotes the uniform vaporization of methanol, and the fluid agitator is installed at the bottom center of the graphite vaporization chamber to promote uniform heating of the liquid. The catalyst pipe is connected to the graphite vaporization chamber to provide the necessary catalyst to accelerate the reaction. The preheating component preheats the methanol entering the vaporization chamber to improve the vaporization efficiency. Through the synergistic effect of the above parts, the effective recovery and efficient vaporization of unvaporized methanol are achieved, the work process is optimized, and the effect of improving resource utilization and saving energy and reducing consumption is achieved.

[0016] Furthermore, the control mechanism includes a temperature sensor, a pressure sensor, a heater, and a flow control valve. The temperature sensor and the pressure sensor are installed inside the graphite vaporization chamber.

[0017] By adopting the above technical solution, the temperature sensor and the pressure sensor are installed inside the graphite vaporization chamber to monitor the temperature and pressure in the vaporization chamber in real time. The heater is tightly connected to the graphite vaporization chamber to provide the necessary heat energy to maintain the high temperature conditions required for the esterification reaction. The flow control valve is connected to the graphite vaporization chamber to adjust the material flow entering the vaporization chamber to ensure the stability of the reaction process. In the workflow, the temperature sensor and the pressure sensor feed back the monitored data to the control system, and the control system adjusts the heating power of the heater and the opening of the flow control valve according to the real-time parameters. The working principle is to optimize the vaporization conditions of graphite by accurately controlling the temperature and pressure to ensure the efficient reaction. The effect achieved is to improve the vaporization efficiency and product quality, reduce energy consumption, and enhance the safety and reliability of the system.

[0018] Furthermore, the recovery mechanism includes an annular heat conductive layer, a heat recovery pipe, a heat exchanger, and a thermoelectric conversion module. The annular heat conductive layer is coated on the outer wall of the graphite vaporization chamber. The heat recovery pipe connects the annular heat conductive layer and the heat exchanger. The thermoelectric conversion module is embedded in the annular heat conductive layer to convert waste heat into electrical energy.

[0019] By adopting the above technical solution, the annular heat-conducting layer is coated on the outer wall of the graphite vaporization chamber, which is responsible for absorbing the waste heat generated by the vaporization chamber. The heat recovery pipeline connects the annular heat-conducting layer and the heat exchanger, and transfers the absorbed heat to the heat exchanger for preheating materials entering the system or other purposes. The thermoelectric conversion module is embedded in the annular heat-conducting layer, and uses the thermal difference to directly convert the waste heat into electrical energy, which is supplied to the control mechanism or other electrical equipment in the system. In the working process, the waste heat generated when the graphite vaporization chamber is in operation is first absorbed by the annular heat-conducting layer, and the heat is transferred to the heat exchanger through the heat recovery pipeline for reuse. At the same time, the thermoelectric conversion module converts part of the heat energy into electrical energy. This working principle effectively recovers the waste heat in the system and achieves the effect of energy saving and efficiency improvement. The coordinated effect of each part ensures the full utilization of waste heat and improves the energy efficiency and environmental protection performance of the entire device.

[0020] Production methods include: Step 1: Graphite enters the graphite vaporization chamber and flows through the regulating valve to ensure the appropriate flow rate; Step 2: The graphite vaporization chamber is heated by a heating source, the spiral heat exchange pipe increases the heating area of ​​the graphite, and the agitator promotes uniform heating of the graphite. The graphite reacts with water vapor or oxygen at high temperature in the graphite vaporization chamber to generate synthesis gas rich in carbon monoxide and hydrogen.

[0021] Step 3: Under the action of the multi-layer manifold assembly, the synthetic gas forms a uniform liquid film and air flow path, further improving the vaporization efficiency.

[0022] Step 4: The high-temperature gas generated during the vaporization process passes through the recovery mechanism, and the residual heat is absorbed by the annular heat-conducting layer and the thermoelectric conversion module, which is used to preheat the incoming graphite or supply electrical energy to the control system.

[0023] Step 5: The synthesis gas enters the catalyst chamber and is synthesized into methanol in a suitable temperature control mechanism and pressure mechanism. The generated methanol is collected after condensation and separation, and the unreacted synthesis gas can be recycled.

[0024] Compared with the prior art, the present invention has the following beneficial effects: First, the vaporizer forms an efficient circulation system by including a recovery mechanism, a screening mechanism, a collection mechanism and a control mechanism.

[0025] Secondly, the screening mechanism includes a screening cylinder, a multi-stage spiral wind cylinder, a fan, a shearing assembly, a gear assembly and a screening motor. The screening motor is tightly connected to the screening cylinder to provide a power source, and is connected to the multi-stage spiral wind cylinder for rotation through the gear assembly.

The fan is tightly connected to the multi-stage spiral wind cylinder to enhance the fluidity of the material. The shearing assembly is fixed on the screening cylinder to shear the incoming material. Through the coordinated work of these parts, efficient separation and screening of materials of different particle sizes are achieved, the screening accuracy and efficiency are improved, and the effective processing of materials and the smooth progress of subsequent processes are ensured.

[0026] Again, the shearing assembly includes a shearing shell, a first shearing plate, a second shearing plate, a shearing motor, a first shearing bead and a second shearing bead. The shearing motor is tightly connected to the second shearing plate to drive the first shearing plate to rotate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 - Figure 6 As shown, the present invention provides a graphite methanol vaporizer with heat recovery function and a production method technical solution: The vaporizer includes a recovery mechanism 1, a screening mechanism 2, a collecting mechanism 3, and a control mechanism 4.

[0034] By adopting the above technical solution, the screening motor 26 is tightly connected to the screening cylinder 21 to provide a power source, and drives the multi-stage spiral wind cylinder 22 to rotate through the gear assembly 25 connected by transmission. The multi-stage spiral wind cylinder 22 is rotatably connected to the screening cylinder 21, and is provided with a spiral groove 221 and a step-by-step screening hole 222, and these wind cylinders are arranged in a step-down manner, and the aperture decreases step by step from the outside to the inside. The fan 23 is tightly connected to the multi-stage spiral wind cylinder 22 to enhance the fluidity of the material. The shearing assembly 24 is fixed on the screening cylinder 21 to shear the incoming material. In the work process, the screening motor 26 drives the multi-stage spiral wind cylinder 22 to rotate, and the material is screened by the step-by-step screening hole 222 under the guidance of the spiral groove 221, and the airflow provided by the fan 23 accelerates the material to pass through the sieve hole. The shearing assembly 24 shears larger particles to promote their passage through the sieve hole. Through this working principle, efficient separation and screening of materials of different particle sizes are achieved, the screening accuracy and efficiency are improved, and the effective processing of materials and the smooth progress of subsequent processes are ensured.

[0035] Furthermore, the shearing assembly 24 includes a shearing shell 241, a first shearing plate 242, a second shearing plate 243, a shearing motor 244, a first shearing bead 245, and a second shearing bead 246. The shearing motor 244 and the second shearing plate 243 are fastened together, the second shearing plate 243 and the shearing shell 241 are fastened together, the shearing motor 244 and the first shearing plate 242 are transmission-connected, the first shearing bead 245 and the first shearing plate are rotationally connected, the second shearing bead 246 and the second shearing plate 243 are rotationally connected, the first shearing bead 245 and the second shearing bead 246 abut against each other, an upper shearing hole 2421 is provided on the first shearing plate 242, and a lower shearing hole 2422 is provided on the second shearing plate 243.

The rotation of the transmission gear 251 is transmitted to the multi-stage spiral wind drum 22 through the transmission gear column 252. Since the transmission gear column 252 is gear-engaged with the rotating tooth groove 223 on the wind drum, the multi-stage spiral wind drum 22 can rotate stably and effectively. This working principle ensures the efficient transmission of power from the motor to the wind drum. The effect achieved is that the power transmission system of the entire screening mechanism 2 runs smoothly, reduces energy loss, and improves screening efficiency.
