Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a device and system for depolymerizing waste high-molecular organic matter. Background Technology

[0002] In waste recycling technologies, recycled waste products need to undergo multiple processing steps to achieve resource recycling. For example, for high-molecular-weight organic materials such as rubber, plastics, and biomass, depolymerization processes are typically used to break them down into smaller molecule compounds through chemical or physical methods.

[0003] However, during the process, the recycled waste products are usually composed of a variety of materials, including impurities such as high molecular weight organic compounds and metallic materials. It is necessary to completely separate these impurities from the waste high molecular weight organic compounds during the pretreatment stage. However, due to various factors, the impurities may not be completely separated, and the residual impurities can affect the depolymerization process.

[0004] Specifically, because impurities such as metallic materials have high melting points, they remain intact during the depolymerization process. They fall due to gravity and accumulate on the air distributor, clogging it and causing uneven airflow distribution. This affects the uniformity of the heat transfer fluid, reduces pyrolysis efficiency, and lowers product quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device for depolymerizing waste high-molecular organic matter. By setting a separation component, the blockage of the air distributor is avoided, which prevents uneven airflow distribution and affects the uniformity of the heat carrier, thereby improving the pyrolysis efficiency and product quality. The above setting can solve the problem that impurities are easy to accumulate on the air distributor, which will lead to uneven airflow distribution, affect the uniformity of the heat carrier, and reduce the pyrolysis efficiency and product quality.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An apparatus for depolymerizing waste high-molecular organic compounds is provided, comprising:

[0008] The furnace body has a heat carrier inlet and a dry distillation gas outlet on its side wall.

[0009] An air distributor is fixedly connected to the inner wall of the furnace body, with the heat carrier inlet located below the air distributor and the dry distillation gas outlet located above the air distributor.

[0010] A separation component is disposed above the air distributor. The separation component includes multiple separation rods for assisting in the separation of residual impurities in waste high-molecular organic matter.

[0011] Optionally, the plurality of the separating rods are arranged in a circumferential array and form a conical structure.

[0012] The separation component also includes:

[0013] A ring rod is detachably connected to the inner wall of the furnace body, and the outer ends of the plurality of separating rods are fixedly connected to the ring rod;

[0014] Multiple diagonal braces are connected to the separating rod and extend diagonally upward.

[0015] Optionally, the separation assembly further includes a lifting rod, which is inserted into the top of the furnace body, and the inner ends of the annular rod are all connected to the lifting rod.

[0016] Optionally, the inclined rod protrudes from the surface formed by the separating rod, and the separating rod, the ring rod, and the inclined rod are integrally manufactured.

[0017] Optionally, multiple support rods are fixedly connected to the inner wall of the furnace body at positions corresponding to the annular rods, and the multiple support rods are arranged in a circular array around the central axis of the furnace body.

[0018] Optionally, the free end of the support rod is provided with a limiting groove that matches the annular rod.

[0019] Optionally, the air distributor is umbrella-shaped, comprising spaced-apart ribs, with air guides between adjacent ribs, and a grid formed between the air guides and the ribs.

[0020] Optionally, the air distributor includes at least two umbrella-shaped structures, and each umbrella-shaped structure includes the umbrella ribs, and the grilles are evenly distributed along the circumferential and axial directions.

[0021] Optionally, the heat carrier inlet and the dry distillation gas outlet are located on opposite sides of the furnace body.

[0022] A system for depolymerizing waste polymeric organic matter is also provided, including the device for depolymerizing waste polymeric organic matter as described in any of the above claims and a dry distillation gas circulation component. The dry distillation gas circulation component is disposed between the heat carrier inlet and the dry distillation gas outlet, and is used to convert the dry distillation gas output from the dry distillation gas outlet into a heat carrier and then reintroduce it into the heat carrier inlet.

[0023] Compared with the prior art, this utility model has at least the following beneficial effects:

[0024] In the above scheme, by setting up a separation component, blockage of the air distributor is avoided, which prevents uneven airflow distribution and affects the uniformity of the heat carrier, thereby improving pyrolysis efficiency and product quality.

[0025] By setting up a combination of separating rods and inclined rods, the evenly distributed separating rods and inclined rods form a three-dimensional screen, which can effectively prevent impurities from accumulating on the air distributor and affecting the uneven airflow. The inclined rods and separating rods form an angle, which facilitates the interception and limitation of impurities, improving the efficiency and convenience of impurity separation.

[0026] By setting a limiting groove and a ring rod, the curvature at the bottom of the limiting groove facilitates the locking and placement of the ring rod, and the wide opening at the top of the limiting groove facilitates the smooth sliding of the ring rod into the limiting groove when the separating rod falls, making it easy to clean the collected impurities. The separating rod can be raised and lowered easily while ensuring the overall structural stability of the separating rod. Attached Figure Description

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0041] Generally, terms can be understood at least partly from their use in context.

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0042] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0043] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0044] like Figures 1 to 6 As shown, an embodiment of this utility model provides a device for depolymerizing waste polymeric organic matter, including a furnace body 1, on which a heat carrier inlet 2 and a dry distillation gas outlet 3 are provided; an air distributor 4, which is fixedly connected to the inner wall of the furnace body 1, with the heat carrier inlet 2 located below the air distributor 4 and the dry distillation gas outlet 3 located above the air distributor 4; and a separation component, which is disposed above the air distributor 4 and includes multiple separation rods 5 for assisting in the separation of residual impurities in the waste polymeric organic matter.

[0045] The high-temperature heat carrier enters the middle section of the furnace body 1 through the heat carrier inlet 2 and the air distributor 4, and achieves efficient depolymerization of waste products through direct heating. After depolymerization, the residual carbon is discharged from the bottom of the furnace body 1, and the dry distillation gas is discharged from the dry distillation gas outlet 3.

[0046] Specifically, the air distributor 4 can prevent waste products from falling while allowing gas to pass through smoothly. The heat carrier is introduced into the air distributor 4 and flows from bottom to top into the waste product layer, achieving a uniform distribution of the heat carrier on the cross-section of the layer. Since there are still residual impurities in the waste products that have not been completely separated, as the products enter pyrolysis, the impurities remain intact due to their high melting point and have a high density and large self-weight. This characteristic makes it easy for the impurities to fall and accumulate on the separation rod 5 under the action of gravity in the device.

[0047] The waste product can be waste tires, the device can be a depolymerization furnace, and the impurities can be steel wires. A portion of the dry distillation gas generated after the waste tires are depolymerized is used as a heat carrier and is first introduced into the device. Inside the device, the heat generated by the combustion of the dry distillation gas is used to regenerate and heat the heat carrier to a temperature of over 600°C. The high-temperature heat carrier flows evenly to the middle section of the depolymerization furnace through an air distributor, and the waste tires are depolymerized efficiently through direct heating. After depolymerization is completed, the waste tire carbon residue is discharged from the bottom of the depolymerization furnace, the dry distillation gas is discharged from the top of the depolymerization furnace, and the steel wires fall and accumulate on the separation rod 5.

[0048] In the above scheme, by setting up a separation component, blockage of the air distributor 4 is avoided, preventing uneven airflow distribution and affecting the uniformity of the heat transfer medium, thereby improving pyrolysis efficiency and product quality. Furthermore, residual impurities after separation can be effectively collected.

[0049] In one embodiment of this utility model, multiple separating rods 5 are arranged in a circumferential array and form a conical structure; the separating assembly also includes: an annular rod 6, which is detachably connected to the inner wall of the furnace body 1, and the outer ends of multiple separating rods 5 are all fixedly connected to the annular rod 6; and multiple inclined rods 7, which are connected to the separating rods 5 and extend obliquely upward.

[0050] By setting the separation rod 5 and the inclined rod 7 together, the evenly distributed separation rod 5 and the inclined rod 7 form a three-dimensional screen, which can effectively collect residual impurities in waste high molecular organic matter, avoid impurities from accumulating on the air distributor 4 and affecting the uneven airflow. The inclined rod 7 and the separation rod 5 form an angle, which facilitates the interception and limitation of impurities, improving the efficiency and convenience of impurity separation.

[0051] In one embodiment of this utility model, the separation assembly further includes a lifting rod 8, which is inserted into the top of the furnace body 1, and the inner ends of the annular rod 6 are all connected to the lifting rod 8. After the waste product pyrolysis is completed, the lifting rod 8 can be used to lift the separation rod 5 upward as a whole to clean the impurities collected on the separation rod 5, and after cleaning, the separation rod 5 is lowered back onto the support rod 9.

[0052] In one embodiment of this utility model, the inclined rod 7 protrudes from the surface formed by the separating rod 5. The separating rod 5, the ring rod 6, and the inclined rod 7 are integrally manufactured structures, and the three can be manufactured uniformly during the production process. This arrangement makes the processing technology simpler and easier to manufacture.

[0053] In one embodiment of this invention, multiple support rods 9 are fixedly connected to the inner wall of the furnace body 1 at positions corresponding to the annular rod 6. These support rods 9 are arranged in a circular array around the central axis of the furnace body 1. The multiple support rods 9 are used to support the annular rod 6 along its circumference.

[0054] In one embodiment of this utility model, a limiting groove 10 matching the annular rod 6 is provided on the free end of the support rod 9 to lock the annular rod 6 and prevent it from shifting during the depolymerization process.

[0055] By setting a limiting groove 10 and an annular rod 6 in cooperation, the curvature of the bottom of the limiting groove 10 facilitates the snapping and placement of the annular rod 6, and the wide opening at the top of the limiting groove 10 facilitates the smooth sliding of the annular rod 6 into the limiting groove 10 when the separating rod 5 falls, making it easy to clean the collected impurities. The separating rod 5 can be raised and lowered easily, while ensuring the overall structural stability of the separating rod 5.

[0056] Furthermore, the limiting groove 10 has a downward curvature, and the outer contour diameter of the top of the limiting groove 10 is larger than the diameter of the circular rod / annular rod 6.

[0057] In one embodiment of this utility model, the outer diameter of the annular rod 6 is smaller than that of the air distributor 4. The outer diameter of the air distributor 4 is adapted to the diameter of the inner wall of the furnace body 1, and the size of the annular rod 6 facilitates its vertical movement within the furnace body 1.

[0058] In one embodiment of this utility model, the air distributor 4 is umbrella-shaped and includes spaced-apart umbrella ribs. There are air guide rods between adjacent umbrella ribs, and a grid is formed between the air guide rods and the umbrella ribs to prevent waste products from falling while allowing gas to pass through smoothly.

[0059] In one embodiment of this invention, the air distributor 4 includes at least two umbrella-shaped structures, each of which includes ribs, and the grilles are evenly distributed along the circumferential and axial directions. That is, the upper and lower grilles are arranged alternately, further improving the gas passage effect.

[0060] In one embodiment of this invention, the heat carrier inlet 2 and the distillation gas outlet 3 are located on opposite sides of the furnace body 1. The high-temperature heat carrier enters the middle section of the furnace body 1 through the heat carrier inlet 2 and the air distributor 4, while the resulting distillation gas exits from the distillation gas outlet 3. Positioning the heat carrier inlet 2 and the distillation gas outlet 3 on opposite sides of the furnace body 1 prevents the high-temperature heat carrier from flowing only on one side within the furnace body 1, promoting full contact between the heat carrier and the product and improving the depolymerization effect.

[0061] Furthermore, after depolymerization, the oil is separated into various types of oil products by passing through different stages of coolers.

[0062] In one embodiment of this utility model, the heat carrier is introduced into the inner side of the air distributor 4 and flows from bottom to top through the grid into the waste product material layer, achieving a uniform distribution of the heat carrier on the cross-section of the material layer. The air distributor 4 has a conical structure that is thinner at the top and thicker at the bottom. The outer contour of the bottom of the upper layer of the air distributor 4 is fixedly connected to the inner wall of the furnace body 1. The separation rod 5 is set directly above the air distributor 4 and is concentrically arranged with the air distributor 4 (e.g., Figure 1 As shown), the separating rod 5 and the air distributor 4 do not contact each other. The separating rod 5 are arranged in a circular array around the central axis of the lifting rod 8, forming an overall conical structure that is thinner at the top and thicker at the bottom (as shown). Figures 4 to 6 (As shown).

[0063] Furthermore, evenly distributed support rods 9 are fixedly connected to the inner wall of the furnace body 1. The free end of each support rod 9 is provided with a limiting groove 10 with a downwardly curved arc. The connection between the limiting groove 10 and the support rod 9 is rounded, resulting in a wide-mouthed arc at the top of the limiting groove 10 (e.g., ...). Figure 5 As shown in the figure, the limiting groove 10 and the annular rod 6 cooperate with each other to achieve the function of supporting the annular rod 6 with the support rod 9, so as to ensure the overall structural stability of the separation rod 5. The lifting rod 8 at the top of the separation rod 5 extends to the top of the furnace body 1. After the waste product is pyrolyzed, the lifting rod 8 can be lifted upward by electric drive. The specific structure and working principle of the electric drive to control the lifting rod 8 are existing public technology and will not be described in detail here. This drives the separation rod 5 to be lifted upward to clean the impurities collected on the separation rod 5. After cleaning, when the separation rod 5 is lowered back onto the support rod 9, the wide opening of the limiting groove 10 facilitates the entry of the annular rod 6, thereby achieving the overall structural stability of the separation rod 5.

[0064] The working principle of the technical solution provided by this utility model is as follows:

[0065] In operation, pre-treated waste products are fed into the furnace body 1 from the top. High-temperature heat carrier enters the middle section of the furnace body 1 through heat carrier inlet 2 and air distributor 4. Direct heating achieves efficient deagglomeration of the waste products. The air distributor 4 has a double-layer grid cone structure with alternating upper and lower grids, preventing waste products from falling while allowing gas to pass smoothly. The heat carrier enters the air distributor 4 and flows upward through the grid into the waste product layer, achieving uniform distribution of the heat carrier across the material layer cross-section. Separation rods 5 are positioned directly above and concentrically with the air distributor 4, without contacting it. The separation rods 5 are arranged in a circular array around the central axis of the lifting rod 8, forming a complete... The body has a conical structure that is thinner at the top and thicker at the bottom. The outer diameter of the bottom of the separating rod 5 is smaller than that of the air distributor 4. The free ends of the separating rods 5 are all fixedly connected to the ring rod 6. Each separating rod 5 is fixedly connected with evenly distributed inclined rods 7, and the orientation of the inclined rods 7 is staggered on both sides of the separating rod 5, so that the inclined rods 7 on the opposite surfaces of adjacent separating rods 5 face the center of the adjacent separating rod 5, and the inclined rods 7 have an inclination angle with the separating rod 5. The separating rods 5, the ring rod 6, and the inclined rods 7 are manufactured as a single piece. Since there are still residual impurities in the waste products that have not been completely separated, as the products enter pyrolysis, the impurities remain intact due to their high melting point and have high density and large self-weight. This characteristic makes the impurities... In the device, impurities easily fall and accumulate on the separating rod 5 under the influence of gravity. The evenly distributed inclined rods 7 on the separating rod 5 form a three-dimensional screen, collecting impurities on the inclined rods 7, thus not affecting the effect of the air distributor 4. The separating rod 5, the ring rod 6, and the inclined rods 7 are an integral manufacturing structure, and all three can be manufactured uniformly during the production process. This design simplifies the processing technology and makes manufacturing easier. The limiting groove 10 cooperates with the ring rod 6, using the support rod 9 to support the ring rod 6, and the ring rod 6 falls into the limiting groove 10. The arc-shaped bottom of the limiting groove 10 ensures that the ring rod 6 is firmly located in the limiting groove 10, thus ensuring the overall structural stability of the separating rod 5. The lifting rod 8 at the top of the separating rod 5 extends to the top of the furnace body 1. After the pyrolysis of the waste products is completed, the lifting rod 8 can be used to lift the separating rod 5 upwards to clean the impurities collected on the separating rod 5. After cleaning, when the separating rod 5 is lowered back onto the support rod 9, the wide opening of the limiting groove 10 facilitates the entry of the annular rod 6, thereby achieving overall structural stability of the separating rod 5. After depolymerization is completed, the residual carbon is discharged from the bottom of the furnace body 1, and the dry distillation gas is discharged from the dry distillation gas outlet 3. Various oil products are separated by passing through each stage of coolers. The device provided in this application avoids clogging of the air distributor 4, avoids uneven airflow distribution and affects the uniformity of the heat carrier, thereby improving the pyrolysis efficiency and product quality.

[0066] Please see Figure 7Furthermore, a system for depolymerizing waste polymeric organic matter is provided, comprising the apparatus 100 for depolymerizing waste polymeric organic matter as described in any of the above claims and a dry distillation gas circulation component. The dry distillation gas circulation component is disposed between the heat carrier inlet and the dry distillation gas outlet, and is used to convert the dry distillation gas output from the dry distillation gas outlet into a heat carrier and then reintroduce it into the heat carrier inlet.

[0067] In this embodiment, after depolymerization, the residual carbon is discharged from the bottom of the furnace body 1, and the distillation gas is discharged from the distillation gas outlet 3, passing through various stages of coolers in sequence. Specifically, the heavy oil is separated by the primary cooling unit 400, the medium oil by the secondary cooling unit 500, and the light oil and distillation gas by the tertiary cooling unit 600. The various oil products are then recycled into the corresponding heavy oil storage tank 700, medium oil storage tank 800, and light oil storage tank 900, respectively. The distillation gas is recycled, with part of it used as a heat carrier and the other part used as fuel for combustion and heating.

[0068] The heat carrier regenerative heating method includes: the combustion of dry distillation gas to generate high-temperature flue gas, which heats the heat storage body A200 (heat storage process), while the heat storage body B300 heats the dry distillation gas of the heat carrier (heat release process).

[0069] It should be noted that the two heat storage bodies, A200 and B300, alternately store and release heat. In the above scheme, by setting up a separation component, blockage of the air distributor 4 is avoided, preventing uneven airflow distribution and affecting the uniformity of the heat transfer medium, thereby improving pyrolysis efficiency and product quality. Furthermore, residual impurities after separation can be effectively collected. By setting up a pyrolysis gas circulation component, the pyrolysis gas can be recycled.
