Description

Technical Field

[0001] This invention relates to the field of coal processing technology, specifically to a combined production device and process for gravity interference bed sorting and ash reduction and leaching and chlorination reduction. Background Technology

[0002] The chlorine content in coal is typically between 0.02% and 0.1%; coal with a chlorine content exceeding 0.2% is considered high-chlorine coal. Combustion of high-chlorine coal causes chloride ions to dissolve in water vapor and enter the boiler system. Under high temperature and pressure, these ions react and transform into chlorides and acidic substances such as HCl and H₂SO₄, causing varying degrees of corrosion to boiler pipes and equipment. The ash from high-chlorine coal also releases large amounts of chloride salts and heavy metals, clogging boilers and polluting the environment. Therefore, high-chlorine coal requires dechlorination treatment before use to avoid these problems.

[0003] Conventional dechlorination methods involve soaking high-chlorine coal in specialized soaking tanks or pools using water at a specific temperature to remove chlorine. The dechlorinated coal is then sorted and graded. This process is divided into two main steps, resulting in low dechlorination efficiency. Furthermore, different particle sizes within the same soaking tank exhibit varying dechlorination effects, leading to inconsistent results. Additionally, coal dechlorination and coal washing are typically performed as separate steps, resulting in slow overall operation, high water consumption, and low water resource utilization. Therefore, improvements and optimizations to existing technologies are necessary. Summary of the Invention

[0045] The working principle and beneficial effects of this invention are as follows:

[0046] In this invention, the combined production device includes a base frame, interference units, and filter units. The number of interference units is preferably three, namely unit A, unit B, and unit C. Each interference unit includes a cylinder, a feed cylinder, a baffle, and a discharge pipe. The number of filter units is preferably six, with each filter unit corresponding to one discharge pipe or one overflow port. The filter units can be selected from existing equipment, which has the function of separating coal and water.

[0047] By utilizing the impact of water flow on the materials in the interference bed, the materials are kept in an active tumbling state, increasing the full contact between water and materials. This allows for dechlorination treatment of the materials while they are being sorted. The continuous operation of these three interference units enables continuous material sorting, improving sorting accuracy. Simultaneously, the continuous operation of the three interference units also allows for thorough soaking of the materials, enhancing the dechlorination effect. During the process, products with different requirements can be obtained according to various product needs.

[0048] The material is filtered by a filtration unit to obtain circulating water three, circulating water four, circulating water five and circulating water six with different chlorine contents. One or more of them are mixed and then sent to the first interference unit to sort and dechlorinate the material with the highest chlorine content. By utilizing the difference in chlorine concentration in the circulating water, the utilization rate of the circulating water is improved, and the consistency of the sorting effect of the interference unit is also improved.

[0049] In addition to the above effects, this technical solution also has other beneficial benefits. Besides achieving coal sorting and dechlorination, this solution requires minimal on-site modifications, mainly involving changes to the number of equipment and related connecting parts. Furthermore, this technical solution has wide applicability; even existing processing sites can be quickly adjusted and modified, making it easy to operate. Even in sites with limited space, materials can be conveyed to other areas via conveyor belts or pipes for continued dechlorination treatment, efficiently utilizing existing space. Targeted modifications to the site are also possible, significantly promoting the further development and application of clean coal treatment technology. From an operational perspective, aside from natural wear and tear on the equipment, the primary energy consumption is water, mainly from natural evaporation during water circulation and the moisture content in the product. Water consumption costs are relatively low, resulting in lower overall operating costs. Attached Figure Description

[0058] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0060] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0061] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0062] Example 1, refer to Figures 1-5 The first embodiment of the present invention proposes a combined production device for gravity interference bed sorting and ash reduction and leaching and chlorination reduction.

[0063] In this embodiment, the combined production device includes a base frame 1, interference units 2, and filter units 13. The number of interference units 2 is preferably three, namely unit A, unit B, and unit C. Each interference unit 2 includes a cylinder 3, a feed cylinder 7, a baffle 8, and a discharge pipe 12. The number of filter units 13 is preferably six, and each filter unit 13 corresponds to one discharge pipe 12 or one overflow port 6. The filter units 13 can be selected from existing equipment, which has the function of separating coal and water.

[0064] In operation, the raw material coal first enters unit A. The material enters the upper end of the upper chamber 10 through the feed cylinder 7. Water flows into the lower chamber 11 through the inlet 5. Then, the water in the lower chamber 11 enters the lower end of the upper chamber 10 through the turbulence hole 9. In the upper chamber 10, the material is impacted by the upward flow of water, causing the material to be in an active tumbling state, improving the full contact between water and material. The material rises and falls according to its specific gravity. The floating material is discharged through the overflow port 6. After being filtered by the first filter unit 13, product one and circulating water one are obtained. Product one enters unit C. The sinking material is discharged through the discharge pipe 12. After being filtered by the second filter unit 13, product two and circulating water two are obtained. Product two enters unit B.

[0065] Compared to Unit C, Product 1, as the raw material of Unit C, enters the interference chamber 4 through the feed cylinder 7, repeats the process in Unit A, and finally, after passing through the overflow port 6 and the third filter unit 13, Product 3 and circulating water 3 are obtained; after passing through the discharge pipe 12 and the fourth filter unit 13, Product 4 and circulating water 4 are obtained.

[0066] Compared to Unit B, Product 2, as the raw material of Unit B, enters the interference chamber 4 through the feed cylinder 7, repeats the process in Unit A, and finally, after passing through the overflow port 6 and the fifth filter unit 13, it becomes Product 5 and circulating water 5; after passing through the discharge pipe 12 and the sixth filter unit 13, it becomes Product 6 and circulating water 6.

[0067] In the above process, the conveying device is activated; a conveyor belt or conveying pipe, as used in existing technology, can be used. Using a separate conveying device, product four and product two are mixed and conveyed together to unit B. Similarly, using a separate conveying device, product five and product one are mixed and conveyed together to unit C. Through the continuous operation of these three interference units 2, the materials are continuously sorted, improving sorting accuracy. Simultaneously, the continuous operation of the three interference units 2 also allows for thorough soaking of the materials, improving dechlorination efficiency. During the process, different products can be obtained according to different product requirements.

[0068] During operation, by comparing the chlorine content of the materials along their flow direction, it can be determined that the chlorine content is higher for raw material than for product 2, and higher for product 1 than product 3, and higher for product 4, and higher for product 2 than product 5, and higher for product 6. The initial water flow enters units B and C respectively. Utilizing the difference in chlorine content between the water and the materials, the initial water flow performs secondary sorting and dechlorination on products 1 and 2, which have lower chlorine content, resulting in circulating water 3, 4, 5, and 6 with certain chlorine content. One or more of these are then used as the initial water flow for unit A and enter the interference chamber 4 of unit A to sort and dechlorinate the raw material with the highest chlorine content. By utilizing the difference in chlorine concentration in the circulating water, the utilization rate of the circulating water is improved, while the consistency of the sorting effect in interference unit 2 is also enhanced.

[0069] In addition to the above effects, this technical solution also has other beneficial benefits. Besides achieving coal sorting and dechlorination, this solution requires minimal on-site modifications, mainly involving changes to the number of equipment and related connecting parts. Furthermore, this technical solution has wide applicability; even existing processing sites can be quickly adjusted and modified, making it easy to operate. Even in sites with limited space, materials can be conveyed to other areas via conveyor belts or pipes for continued dechlorination treatment, efficiently utilizing existing space. Targeted modifications to the site are also possible, significantly promoting the further development and application of clean coal treatment technology. From an operational perspective, aside from natural wear and tear on the equipment, the primary energy consumption is water, mainly from natural evaporation during water circulation and the moisture content in the product. Water consumption costs are relatively low, resulting in lower overall operating costs.

[0070] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Based on the first embodiment, this embodiment further refines the number of interference units 2. The number of interference units 2 can be four or more, where there is only one unit A, and the number of units B and C can be several. The number of units B and C can be appropriately selected according to the actual sorting effect of unit A. Taking five interference units 2 as an example, there is one unit A, two units B, and two units C. After sorting by unit A, product one and product two are obtained. Product one flows to the first unit C, and product two flows to the first unit B. This process is the same as in the first embodiment and will not be described again. Finally, product three and product six are obtained.

[0071] The product flows to the second unit C. The material discharged from the discharge pipe 12 of the second unit C is returned to the first unit C for further sorting and dechlorination. This improves the sorting effect and extends the soaking time of water and material, thus improving the dechlorination effect. The material discharged from the overflow port 6 of the second unit C is one of the final products.

[0072] After product 6 flows to the second unit B, the material discharged from the overflow port 6 of the second unit B returns to the first unit B for further sorting and dechlorination. The material discharged from the discharge pipe 12 of the second unit B is one of the final products.

[0073] Similarly, when there are more units B and units C, the material discharged from the overflow port 6 of the second and subsequent units B is returned to the previous unit B for further sorting and dechlorination, and the material discharged from the discharge port of the second and subsequent units C is returned to the previous unit C for further sorting and dechlorination.

[0074] Example 3, referring to Figures 1-6 This is the third embodiment of the present invention. Based on the second embodiment, this embodiment further refines the combined production device by adding a dispersing component 14, an adjusting cylinder 16, an adjusting component 18, a snap-fit ​​component 20, a locking support component 21, and a locking component 22. During operation, after the material is put into the interference chamber 4 of the cylinder 3, it is diffused by the dispersing component 14, which facilitates the full contact between the material and the water, realizes the rapid rise, fall, sinking and floating of the material, and improves the sorting speed.

[0075] Meanwhile, the aerodynamic component 8 can be adjusted according to different raw material and product requirements; the specific adjustment process is as follows:

[0076] An external force is applied to drive the locking member 22 to rotate. The threaded connection between the locking member 22 and the locking support member 21 adjusts the distance between the locking member 22 and the adjusting cylinder 16. As the locking member 22 gradually approaches the adjusting cylinder 16, it pushes the snap-fit ​​member 20 towards the discharge pipe 12. At this time, the snap-fit ​​member 20 slides within the through hole 17. The structure of the snap-fit ​​member 20 is as follows: Figure 5 and Figure 6 As shown, the snap-fit ​​component 20 includes a sliding post 23, a main body 24, and a locking head 25 that are fixedly connected in sequence. The sliding post 23 is slidably disposed in the through hole 15, and the main body 24 passes through the through hole 27 and is snapped into the through hole 27. The main body 24 has a parallelogram structure. The locking head 25 is located on the outside of the adjusting cylinder 16 and is rotatably connected to the locking component 22.

[0077] When an external force is applied to drive the locking member 22 to rotate, the locking member 22, as it approaches the regulating cylinder 16, pushes the lock head 25 to slide towards the regulating cylinder 16. At this time, the main body 24 slides within the second through hole 17, and the sliding column 23 slides along the first through hole 15. With the help of the parallelogram structure of the main body 24, the main body 24 pushes the regulating cylinder 16 to rotate around the discharge cylinder, thereby adjusting the overlap between the regulating hole 19 and the turbulence hole 9. This allows for the control of the flow inertia of the water after passing through the turbulence hole 9, thus adjusting the sorting effect of the interference unit 2. When the lock head 25 abuts against the outer wall of the regulating cylinder 16, one side of the locking support member 21 abuts against the side wall of the second through hole 17, reaching a limited position and preventing the snap-fit ​​member 20 from separating from the second through hole 17. The two sides of the main body 24 remain in contact with the two side walls of the second through hole 17, thereby fixing the position of the regulating cylinder 16.

[0078] Example 4, refer to Figures 1-6 This is the fourth embodiment of the present invention. Based on the third embodiment, this embodiment further optimizes the combined production device by adding a sliding member 26. One end of the sliding member 26 extends into the lower chamber 11. The sliding member 26 is slidably and rotatably disposed relative to the lower chamber 11. A snap-fit ​​portion is provided on the sliding member 26 for snapping with the head of the snap-fit ​​member 20. In this embodiment, the turbulence-dispersing member 8 is fixedly connected to the discharge pipe 12, and the discharge pipe 12 is rotatably connected to the cylinder 3. The discharge cylinder is driven to rotate by an external power source, which in turn drives the turbulence-dispersing member 8 to rotate. The rotating turbulence-inducing component 8 drives the flow of water in the upper chamber 10, improving the flushing effect between water and materials, thereby improving the material sorting effect. When it is necessary to adjust the overlap between the turbulence-inducing hole 9 and the adjusting hole 19, the discharge cylinder is rotated to the preset position. At this time, the head of the locking part and the locking component 22 are aligned. An external force is applied to drive the sliding component 26 to slide towards the adjusting cylinder 16 until the locking part and the head of the locking component 22 are locked in place. Then the sliding component 26 stops sliding and starts to rotate. The rotation of the locking component 22 is completed by the sliding component 26, thereby realizing the sliding of the locking component 20 and completing the adjustment operation.

[0079] Example 5, refer to Figures 1-6 The fifth embodiment of the present invention proposes a combined production process of gravity interference bed sorting and ash reduction and leaching and chlorination reduction.

[0080] In this embodiment, the combined production process includes the following steps:

[0081] Step 1: Material feeding. The original material is fed into the cylinder 3 in the first interference unit 2.

[0082] Step 2: Material sorting and dechlorination. The first interference unit 2 is activated, and flowing water is introduced to sort and dechlorinate the coal. Simultaneously, external force is applied to drive the dispersing component 14 to rotate, dispersing the material fed into the cylinder 3. This facilitates full contact between the material and the water flow, improving the coal sorting and dechlorination effects. After sorting in the first interference unit 2, the water-containing material discharged from the overflow port 6 is filtered by the filter unit 13 to obtain product one and circulating water one. The water-containing material discharged from the discharge pipe 12 is filtered by the filter unit 13 to obtain product two and circulating water two. The chlorine in the coal is removed through the material sorting process, achieving simultaneous coal washing and dechlorination.

[0083] The second interference unit 2 is activated, and product 2 is conveyed into it for further sorting and dechlorination. After sorting in the second interference unit 2, the water-containing material discharged from the overflow port 6 is filtered by the filter unit 13 to obtain product 5 and circulating water 5. The water-containing material discharged from the discharge pipe 12 is filtered by the filter unit 13 to obtain product 6 and circulating water 6. Through the second interference unit 2, the heavier materials are sorted and dechlorinated again. This improves the sorting effect and extends the soaking contact time between the heavier materials and water, thereby improving the dechlorination effect and further reducing the chlorine content in the coal.

[0084] The third interference unit 2 is activated, and product one is fed into it for further sorting and dechlorination. After sorting in the third interference unit 2, the water-containing material discharged from the overflow port 6 is filtered by the filter unit 13 to obtain product three and circulating water three. The water-containing material discharged from the discharge pipe 12 is filtered by the filter unit 13 to obtain product four and circulating water four. Through the third interference unit 2, materials with lower specific gravity are sorted and dechlorinated again, preventing materials with higher specific gravity from accidentally entering product one. While improving the sorting effect, the materials with lower specific gravity are soaked and contacted with water again, improving the dechlorination effect and further reducing the chlorine content in the coal.

[0085] The third step involves the use of circulating water. The original water flow is first transported to the second and third interference units 2. By utilizing the difference in chlorine content between the water and the materials, products 1 and 2 with lower chlorine content are subjected to secondary sorting and dechlorination, resulting in circulating water 3, 4, 5, and 6 with certain chlorine content. One or more of these circulating waters are mixed to obtain a liquid that serves as the original water flow from the first interference unit 2 and enters the interference chamber 4 of the first interference unit 2. This allows for the sorting and dechlorination of the original materials with the highest chlorine content. By utilizing the difference in chlorine concentration in the circulating water, the utilization rate of the circulating water is improved, while also enhancing the consistency of the sorting effect in the interference unit 2.

[0086] The fourth step is the recycling of circulating water. Circulating water five and circulating water six are fed into the purification treatment device. The purification treatment device is preferably a device that can filter chlorine-containing water in the prior art, such as a reverse osmosis membrane, or a purification treatment device that uses chemical changes to treat chlorine. If the chlorine concentration in the circulating water needs to be adjusted during the process, any one or more of circulating water three, circulating water four, circulating water five, and circulating water six can be selected and added to circulating water five and circulating water six to adjust the chlorine concentration. Finally, the mixed circulating water is fed into the purification treatment device for purification. The purified circulating water is then fed back into the second and third interference units 2 for recycling, improving water utilization. At the same time, an appropriate amount of original water is added to offset the natural loss of circulating water during the circulation process.

[0087] The above process combines coal washing and dechlorination, improving both the separation and dechlorination effects while reducing water consumption. Furthermore, it requires minimal modification to existing equipment, allowing for direct upgrades and optimizations of existing coal washing plants. The overall equipment changes are minor, the process is simple, improving overall work efficiency and reducing the space required for separate coal dechlorination, thus increasing plant utilization.

[0088] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
