Description
Technical Field

[0002] In the process of cigarette production, cigarette factories need to continuously improve cigarette products, including the improvement of cigarette taste. In order to study the factors that affect the taste of cigarettes, it is necessary to obtain various components in tobacco in the laboratory and conduct experimental research. In the process, the tobacco needs to be pyrolyzed, and then the pyrolysis gas is condensed to obtain pyrolysis oil containing various components in tobacco. The pyrolysis oil is analyzed in the laboratory. In addition, since cigarette factories will produce a certain amount of waste tobacco particles in the process of cigarette production, and the tobacco particles include waste cigarette dust, waste cigarette sheets, etc., cigarette factories usually use these waste tobacco particles for pyrolysis to increase the recycling rate.
[0003] At present, the pyrolysis of tobacco particles is usually carried out using a horizontal quartz tube. A catalyst is placed in the horizontal quartz tube. The flue gas generated by the tobacco particles being heated flows through the horizontal quartz tube. The flue gas forms pyrolysis gas under the action of the catalyst, and then the pyrolysis gas is sent to a condenser for condensation to form pyrolysis oil. The pyrolysis oil can be analyzed in the laboratory. However, there are certain inconveniences in the above process of obtaining pyrolysis oil. For example, after the generated flue gas is sent to the horizontal quartz tube, due to the difference between the flue gas density and the air density, when the flue gas flows through the quartz tube in a horizontal direction, the contact between the flue gas and the catalyst is not uniform enough, and the catalytic effect is not ideal. In addition, after the obtained pyrolysis gas is sent to the condenser for cooling and the pyrolysis oil is obtained, due to the high viscosity of the pyrolysis oil, the pyrolysis oil adheres to the wall of the condenser tube, which is not convenient for subsequent centralized collection.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0028] like Figure 1-Figure 6As shown, the embodiment of the present application provides a tobacco particle pyrolysis condensation device, which is applied to the pyrolysis process of tobacco particles. The waste tobacco particles generated in the production process of the cigarette factory can be pyrolyzed to obtain pyrolysis oil. The composition of the shredded tobacco can be analyzed by analyzing the composition of the pyrolysis oil in the laboratory. At present, when pyrolyzing tobacco particles, a horizontal quartz tube is often used. A catalyst is added to the horizontal quartz tube, and then the tobacco particles are heated. The flue gas generated after the tobacco particles are heated flows through the horizontal quartz tube. The flue gas forms pyrolysis gas under the action of the catalyst, and then the pyrolysis gas is sent to the condenser for condensation treatment, which will Pyrolysis oil is generated and then collected. During the process, due to the difference in density between the smoke generated after the tobacco particles are heated and the air, when the smoke flows through the horizontal quartz tube, the smoke is more concentrated on one side of the horizontal quartz tube. The smoke is not evenly distributed in the cross-sectional direction of the horizontal quartz tube, which makes the contact between the smoke and the catalyst uneven and the catalytic effect needs to be improved. Moreover, the viscosity of the pyrolysis oil generated in the condenser tube is relatively high and the fluidity is poor, which also has certain inconveniences in the collection of the pyrolysis oil. The pyrolysis condensing device of the present application is to improve the contact effect between the smoke and the catalyst and to achieve convenient collection of the pyrolysis oil.
[0029] The tobacco particle pyrolysis and condensation device includes a first pipeline 100 and a second pipeline. The first pipeline 100 is straight and vertically arranged. The top and bottom ends of the first pipeline 100 are both opened. The second pipeline and the first pipeline 100 are connected and communicated with each other to form a channel for material circulation. A loading platform 101 is arranged in the internal cavity of the first pipeline 100. A gap for air flow is arranged on the loading platform 101. A cooling component 200 is arranged on the second pipeline for cooling the material flowing in the second pipeline. A spiral conveying device is arranged in the area corresponding to the cooling component 200 in the second pipeline. In this embodiment, the loading platform 101 can be a flat plate arranged inside the first pipeline 100. Holes are evenly opened on the flat plate, that is, gaps for air flow are formed. A catalyst can be placed on the flat plate. The smoke generated after heating the tobacco particles is fed into the first pipeline 100 from the top end. The smoke flows from top to bottom in the first pipeline 100. The smoke can evenly pass through the catalyst, so that the contact between the smoke and the catalyst is more uniform. Preferably, a layer of aluminum silicate insulation cotton is first laid on the flat plate, and then the catalyst is evenly laid on the layer of aluminum silicate insulation cotton, and then another layer of aluminum silicate insulation cotton is laid on the catalyst, and the tobacco particles to be pyrolyzed are laid on the upper layer of aluminum silicate insulation cotton. The first pipeline 100 is a quartz tube, and the outside of the first pipeline 100 is heated to generate smoke when the tobacco particles are heated. Protective gas such as inert gas can be evenly and continuously introduced into the top of the first pipeline 100, so that the smoke flows smoothly downward through the catalyst. agent, and the tobacco particles and the catalyst are distributed in layers and are roughly parallel, so the flue gas can pass through the catalyst more evenly, which is beneficial to improving the catalytic effect. The flue gas forms pyrolysis gas after being catalyzed by the catalyst. The pyrolysis gas enters the second pipeline through the bottom end of the first pipeline 100, and is condensed to form pyrolysis oil under the cooling effect of the cooling component 200. The pyrolysis oil accumulates on the inner wall of the second pipeline. Under the action of the spiral conveying device, the pyrolysis oil formed in the second pipeline can be conveniently transported forward, which is convenient for the centralized collection of the pyrolysis oil.
[0030] Preferably, a heating component 300 is provided on the second pipeline, and the heating component 300 is used to heat the material flowing in the second pipeline. Along the flow direction of the material in the second pipeline, the heating component 300 is located downstream of the cooling component 200, that is, the condensed pyrolysis oil is first transported forward for a distance by the screw conveying device, and then under the heating action of the heating component 300, the viscosity of the pyrolysis oil is reduced, the fluidity of the pyrolysis oil is improved, and the smooth discharge and collection of the pyrolysis oil are facilitated. Preferably, the heating component 300 includes a heating sleeve 301 sleeved on the outer side of the second pipeline, the second pipeline is a pipe with a circular cross-section, and the heating sleeve 301 is also a pipe with a circular cross-section. Both ends of the heating sleeve 301 are connected to the outer wall of the second pipeline to form a seal, the heating sleeve 301 and the second pipeline of the sleeve part thereof are coaxially arranged, and there is a gap between the inner wall of the middle part of the heating sleeve 301 and the outer wall of the second pipeline, so that the heating sleeve 3 01 and the outer wall of the second pipeline form a heating chamber 302, and the heating chamber 302 is provided with a heat source inlet 303 and a heat source outlet 304. Along the axial direction of the heating sleeve 301, the heat source inlet 303 and the heat source outlet 304 are respectively located at the sides at the two ends of the axial direction of the heating sleeve 301, and in the circumferential direction, the heat source inlet 303 and the heat source outlet 304 are respectively located on different sides of the heating sleeve 301. The heat source is introduced into the heating chamber 302 through the heat source inlet 303, which can increase the heat exchange efficiency between the heat source and the outer wall of the second pipeline. Under the action of heat transfer, the pyrolysis oil in the second pipeline is quickly and effectively heated. In this embodiment, the heat source introduced into the heating chamber 302 uses 80 degrees Celsius heat transfer oil. At this temperature, the pyrolysis oil can maintain good fluidity. The heat transfer oil is transported to the heating chamber 302 from the heat source inlet 303 and discharged from the heat source outlet 304 to form a cycle.
[0031] Preferably, an exhaust port 51 is provided on the second pipeline, and the exhaust port 51 is interconnected with the outside. Along the flow direction of the material in the second pipeline, the exhaust port 51 is located downstream of the cooling component 200. When the protective gas is continuously and evenly introduced through the top of the first pipeline 100, the pyrolysis gas is condensed into pyrolysis oil, and the gas that cannot be condensed is discharged to the outside through the exhaust port 51. In this way, the flow in the first pipeline 100 and the second pipeline is smoother. In this embodiment, along the flow direction of the material in the second pipeline, the exhaust port 51 is located in the area of the second pipeline corresponding to the heating component 300 and tends to be close to the cooling component 200, that is, the exhaust port 51 is provided in the area of the second pipeline corresponding to the heating component 300, and the exhaust port 51 is located in the area of the second pipeline corresponding to the heating component 300, and the exhaust port 51 is located in the area of the second pipeline corresponding to the heating component 300. In the area of the component 300, which is closer to the cooling component 200, in one example, an exhaust pipe 52 is arranged on the exhaust port 51, one end of the exhaust pipe 52 is connected to the exhaust port 51 and is connected to the inside of the second pipe, and the other end of the exhaust pipe 52 passes through the heating chamber 302 and extends from one side of the heating sleeve 301. In this embodiment, the exhaust pipe 52 is arranged close to the end of the heating sleeve 301 close to the cooling component 200, that is, the exhaust pipe 52 extends from the end of the heating sleeve 301 close to the cooling component 200. In this way, the uncondensed low-temperature gas is discharged outward through the exhaust pipe 52 as early as possible, avoiding excessive entry into the area surrounded by the heating sleeve 301, thereby preventing adverse effects on the subsequent pyrolysis oil heating step.
[0032] Preferably, the cooling assembly 200 includes a cooling jacket 201 sleeved on the outside of a part of the second pipeline, the cooling jacket 201 is a tube with a circular cross-section, the cooling jacket 201 and the second pipeline of the sleeved part thereof are coaxially arranged, the two ends of the cooling jacket 201 are sealedly connected to the outer wall of the second pipeline, and there is a gap between the inner wall of the middle part of the cooling jacket 201 and the outer wall of the second pipeline, so that a cooling chamber 202 is enclosed between the cooling jacket 201 and the outer wall of the second pipeline, and a cold source inlet 203 and a cold source outlet 204 are arranged on the cooling chamber 202, and along the axial direction of the cooling jacket 201, the cold source inlet 203 and the cold source outlet 204 are respectively located on the sides of the two end positions of the cooling jacket 201, In the circumferential direction, the cold source inlet 203 and the cold source outlet 204 are respectively located on different sides of the cooling sleeve 201. When the cold source is introduced into the cold source inlet 203 for cooling, the cooling efficiency of the outer wall of the second pipeline can be effectively improved. Under the action of heat transfer, the pyrolysis gas just entering the second pipeline is quickly and effectively cooled. In this embodiment, the cold source introduced into the cooling chamber 202 can be an alcohol solution at minus 5 degrees Celsius. The pyrolysis gas transported by the first pipeline 100 can be fully cooled and form pyrolysis oil under this temperature state. Then the formed pyrolysis oil is transported forward to the area of the heating sleeve 301 by the spiral conveying device for heating, thereby improving the fluidity of the pyrolysis oil.
[0033] In one example, the bottom end of the first pipeline 100 is connected to the second pipeline, and one end of the second pipeline extends in a direction away from the first pipeline 100 and is set to be open. The pyrolysis gas formed in the first pipeline 100 flows downward and enters the second pipeline. The pyrolysis gas condenses to form pyrolysis oil and moves forward driven by the spiral conveying device. After flowing through the area corresponding to the cooling component 200, it enters the area corresponding to the heating component 300. The heated pyrolysis oil continues to move forward and is discharged outward through the opening of the second pipeline.
[0034] Preferably, the second pipeline includes a straight section 401 and an arc section 402, the straight section 401 is arranged horizontally, the direction of the straight section 401 and the direction of the first pipeline 100 are perpendicular to each other, one end of the straight section 401 is connected to one end of the arc section 402, the bottom end of the first pipeline 100 is connected to the side near the other end of the straight section 401 and is connected, the cooling component 200 is arranged on the straight section 401, and the heating component 300 is arranged on the arc section 402, that is, The cooling sleeve 201 is sleeved on the outer side of the part of the straight section 401, and the heating sleeve 301 is sleeved on the outer side of the part of the arc section 402. In this embodiment, the middle part of the arc section 402 is a 90-degree turn structure, and both ends of the arc section 402 are straight-line extended pipe sections. One end of the arc section 402 is connected to one end of the straight section 401, and the other end of the arc section 402 extends downward and opens for pyrolysis oil to be discharged. The screw conveying device includes a screw 601 The screw 601 is arranged in the inner cavity of the straight section 401, the screw 601 and the straight section 401 are arranged coaxially, and the outer diameter of the screw 601 is slightly smaller than the inner diameter of the straight section 401, and the difference between the outer diameter of the screw 601 and the inner diameter of the straight section 401 is 1-2 mm, so as to push the pyrolysis oil on the inner wall of the straight section 401 forward. The end of the straight section 401 away from the arc section 402 is a closed structure, and a through hole is arranged at this end, and the through hole is provided for driving The output end of the device 602 extends into the second pipeline, and the output end of the driving device 602 extends into the second pipeline through the through hole and is coaxially connected to the screw 601 to drive the screw 601 to rotate and transport the pyrolysis oil in the second pipeline.

Bearings and other components can be arranged between the above-mentioned through hole and the output shaft of the driving motor.
[0035] The working principle of the present application is as follows: the catalyst and tobacco particles are laid on the stage 101 in sequence, the tobacco particles are located above the catalyst, the first pipeline 100 is heated, so that the tobacco particles on the stage 101 are heated to generate smoke, a protective gas is introduced above the first pipeline 100, and under the pressure difference formed by the protective gas, the smoke flows downward evenly through the catalyst and the stage 101, and under the action of the catalyst, the smoke forms pyrolysis gas, and the pyrolysis gas flows downward into the straight section 401, and continues to flow. Under the action of the cold source in the cooling chamber 202, the pyrolysis gas in the straight section 401 is condensed to form pyrolysis oil. At this time, the viscosity of the pyrolysis oil is relatively high. Driven by the screw 601, the pyrolysis oil is pushed forward to the arc section 402. Under the action of the heat source in the heating chamber 302, the pyrolysis oil is heated and the fluidity is improved.
