Description

Technical Field

[0001] The present invention relates to the technical field of coal processing, and in particular to a combined production device and production process for gravity interference bed separation and ash reduction and leaching and chlorine reduction. Background Art

[0002] The chlorine content of coal typically ranges from 0.02% to 0.1%. Any content exceeding 0.2% is considered high-chloride coal. The combustion of high-chloride coal causes chloride ions to dissolve in water vapor, entering the boiler system. There, under high temperature and pressure, they react and transform into chlorides and acidic substances such as HCl and H₂SO₄, causing varying degrees of corrosion to boiler piping and equipment. High-chloride coal ash also releases large amounts of chloride salts and heavy metals, clogging boilers and polluting the environment. Therefore, high-chloride coal must be dechlorinated before use to avoid these problems.

[0003] Conventional dechlorination involves placing high-chlorine coal in specialized soaking tanks or immersion tanks, soaking it in water at a constant temperature to extract the chlorine from the coal, and then sorting and grading the dechlorinated coal. This two-step process results in low dechlorination efficiency, and different dechlorination effects vary between coals of different particle sizes within the same soaking tank, resulting in poor consistency. Furthermore, dechlorination and coal washing are typically performed in two separate steps, resulting in low overall efficiency, high water usage, and low water resource utilization. Therefore, improvements and optimization of existing technologies are needed. Summary of the Invention

DETAILED DESCRIPTION

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Example 1, refer to Figures 1 to 5 , which is the first embodiment of the present invention, proposes a combined production device for gravity interference bed separation and ash reduction and leaching and chlorine reduction.

[0026] In this embodiment, the combined production device includes a base frame 1, an interference unit 2 and a filter group 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 spoiler 8 and a discharge pipe 12; the number of filter groups 13 is preferably six, and each filter group 13 corresponds to one of the discharge pipes 12 or an overflow port 6. The filter group 13 can be an equipment in the existing technology, which has the function of separating the material coal and water.

[0027] During use, the raw material coal first enters unit A, and the material enters the upper end of the upper chamber 10 through the feed barrel 7. The water flows into the lower chamber 11 through the water inlet 5, and then the water in the lower chamber 11 enters the lower end of the upper chamber 10 through the turbulent hole 9. In the upper chamber 10, the material is impacted by the upwelling water flow, so that the material is in an active tumbling state, and the full contact between water and material is improved. The material rises and falls according to the specific gravity. The floating material is discharged through the overflow port 6, and after being filtered by the first filter unit 13, the obtained product one and circulating water one enter the unit C; the sinking material is discharged through the discharge pipe 12, and after being filtered by the second filter unit 13, the obtained product two and circulating water two enter the unit B.

[0028] Relative to unit C, product one, as the raw material of unit C, enters the interference chamber 4 through the feed barrel 7, repeats the process in unit A, and finally passes through the overflow port 6 and the third filter unit 13 to obtain product three and circulating water three; after passing through the discharge pipe 12 and the fourth filter unit 13, product four and circulating water four are obtained.

[0029] Relative to unit B, product two, as the raw material of unit B, enters the interference chamber 4 through the feed barrel 7, repeats the process in unit A, and finally passes through the overflow port 6 and the fifth filter unit 13 to obtain product five and circulating water five; after passing through the discharge pipe 12 and the sixth filter unit 13, product six and circulating water six are obtained.

[0030] During the above process, a conveying device is activated, which can be a conveyor belt or a conveyor pipe in the prior art. Product 4 and Product 2 are mixed and conveyed to unit B via a separate conveying device. Product 5 and Product 1 are mixed and conveyed to unit C via a separate conveying device. With the continuous operation of the three interference units 2, the materials are continuously sorted, improving the material sorting accuracy. Furthermore, with the continuous operation of the three interference units 2, the materials can be fully soaked, improving the dechlorination effect. During the process, different products can be obtained according to different product requirements.

[0031] During operation, following the material flow direction, by comparing the chlorine content in the materials, it can be seen that the original material > product two > product one, and product one > product three > product four, and product two > product five > product six. The original water flow enters unit B and unit C respectively. By taking advantage of the difference in chlorine content between the water and the materials, the original water flow is used to perform secondary sorting and secondary dechlorination on products one and two with lower chlorine content, thereby obtaining circulating water three, circulating water four, circulating water five, and circulating water six with certain chlorine content. One or more of these are used as the original water flow of unit A and enter the interference chamber 4 of unit A to sort and dechlorinate the original material with the highest chlorine content. By taking advantage of 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 of interference unit 2 is also improved.

[0032] In addition to the above effects, this technical solution also has other beneficial effects. In addition to achieving the purpose of coal sorting and dechlorination, this technical solution requires little modification to the site, and the main modification is the number of equipment and related matching connectors. At the same time, this technical solution has a wide range of applications. Even for existing treatment sites, it can be quickly adjusted and modified, and is easy to operate. Even if the existing treatment site lacks space, the material can be conveyed to other areas through conveyor belts or conveyor pipes for continued dechlorination treatment, making efficient use of the existing space. Targeted changes can also be made to the site, which has effectively promoted the further development and application of clean coal treatment technology. From the perspective of operation, apart from the natural wear and tear of the equipment, the main consumption is water, and this is mainly reflected in the natural evaporation during the water circulation process and the water contained in the product. The water consumption cost is relatively low, which makes the overall operating cost lower.

[0033] Example 2, refer to Figures 1 to 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, of which there is only one unit A, and the number of units B and units C can be multiple. The number of units B and units C can be appropriately selected according to the actual sorting effect of unit A. The following is an explanation of the number of interference units 2 as five, of which there is one unit A, two units B and two units C. After sorting, unit A produces product 1 and product 2. Product 1 flows to the first unit C, and product 2 flows to the first unit B. This process is the same as that in the first embodiment and is not repeated here. Finally, product 3 and product 6 are obtained.

[0034] Product three flows to the second unit C. The material discharged from the discharge pipe 12 of the second unit C returns to the first unit C for re-sorting and dechlorination. While improving the sorting effect, it also extends the soaking time of water and material, thereby improving the dechlorination effect. The material discharged from the overflow port 6 of the second unit C is one of the final products.

[0035] 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, and the material discharged from the discharge pipe 12 of the second unit B is one of the final products.

[0036] By analogy, 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 re-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 re-sorting and dechlorination.

[0037] Example 3, refer to Figures 1 to 6 This is the third embodiment of the present invention. On the basis of the second embodiment, this embodiment further refines the combined production device and adds a breaking piece 14, an adjusting cylinder 16, an adjusting piece 18, a clamping piece 20, a locking support piece 21 and a locking piece 22. During operation, after the material is put into the interference chamber 4 of the cylinder 3, the breaking piece 14 is used to diffuse the material, which facilitates full contact between the material and water, realizes rapid lifting and sinking of the material, and improves the sorting speed.

[0038] At the same time, the spoiler 8 can be adjusted according to different raw materials and product requirements; the specific adjustment process is as follows: Apply external force to drive the locking member 22 to rotate, and adjust the distance between the locking member 22 and the adjustment cylinder 16 by means of the threaded connection between the locking member 22 and the locking support member 21; when the locking member 22 gradually approaches the adjustment cylinder 16, the locking member 22 will push the clamping member 20 to move in the direction close to the discharge pipe 12, and at this time the clamping member 20 slides in the second through hole 17. The structure of the clamping member 20 is as shown in FIG. Figure 5 and Figure 6 As shown, the clamping member 20 includes a sliding column 23, a main body 24, and a locking head 25 that are fixedly connected in sequence, wherein the sliding column 23 is slidably set in the through hole 15, the main body 24 passes through the through hole 2 17 and is clamped in the through hole 2 17, and the main body 24 is a parallelogram structure as a whole; the locking head 25 is located on the outside of the adjusting cylinder 16, and the locking head 25 is rotationally connected to the locking member 22.

[0039] When an external force is applied to drive the locking member 22 to rotate, the locking member 22 approaches the adjustment cylinder 16 and pushes the lock head 25 to slide in the direction close to the adjustment cylinder 16. At this time, the main body 24 slides in 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 adjustment cylinder 16 to rotate around the discharge cylinder, thereby adjusting the overlap between the adjustment hole 19 and the flow disturbance hole 9, and thus regulating the flow inertia of the water after passing through the flow disturbance hole 9, thereby adjusting the sorting effect of the interference unit 2. When the lock head 25 abuts the outer wall of the adjustment cylinder 16, one side of the locking support 21 abuts the side wall of the second through hole 17, reaching a limited position, preventing the clamping member 20 from separating from the second through hole 17. The two side edges of the main body 24 maintain an abutting state with the two side walls of the second through hole 17, thereby fixing the position of the adjustment cylinder 16.

[0040] Example 4, refer to Figures 1 to 6 , which is the fourth embodiment of the present invention. On the basis of the third embodiment, this embodiment further optimizes the joint production device and adds a sliding member 26. One end of the sliding member 26 extends into the lower chamber 11. The sliding member 26 slides and rotates relative to the lower chamber 11. A clamping portion is provided on the sliding member 26, which is used to clamp with the head of the clamping member 20. In this embodiment, the spoiler 8 and the discharge pipe 12 are fixedly connected, and the discharge pipe 12 and the cylinder 3 are rotatably connected. The discharge barrel is driven to rotate by an external power source, and then the discharge barrel drives the spoiler 8 to rotate. The auxiliary rotating spoiler 8 drives the flow of water in the upper chamber 10, improves the impact effect between water and material, and thus improves the material sorting effect; when it is necessary to adjust the overlap between the spoiler hole 9 and the adjustment hole 19, the discharge barrel is rotated to a pre-set position. At this time, the clamping part is aligned with the head of the locking part 22, and an external force is applied to drive the sliding part 26 to slide in the direction close to the adjustment barrel 16 until the clamping part and the head of the locking part 22 are clamped in place, and then the sliding part 26 stops sliding and starts to rotate. With the help of the sliding part 26, the rotation of the locking part 22 is completed, and then the sliding of the clamping part 20 is realized to complete the adjustment operation.

[0041] Example 5, refer to Figures 1 to 6 , which is the fifth embodiment of the present invention, proposes a combined production process of gravity interference bed separation for ash reduction and leaching for chlorine reduction.

[0042] In this embodiment, the combined production process includes the following steps: Step 1: Material loading: put the original material into the cylinder 3 in the first interference unit 2.

[0043] Step 2: Material sorting and dechlorination. Start the first interference unit 2, let in running water, sort and dechlorinate the coal material, and at the same time apply external force to drive the scattering piece 14 to rotate, breaking up the material put into the cylinder 3; this facilitates full contact between the material and the water flow, and improves the coal sorting and dechlorination effects. After the first interference unit 2 sorts, the water-containing material discharged from the overflow port 6 is filtered by the filter unit 13 to obtain product 1 and circulating water 1, and the water-containing material discharged from the discharge pipe 12 is filtered by the filter unit 13 to obtain product 2 and circulating water 2. The chlorine contained in the coal is removed by means of the material sorting process, realizing the simultaneous washing and dechlorination of the coal.

[0044] The second interference unit 2 is activated, and product two is transported to the second interference unit 2 for further sorting and dechlorination. After sorting by 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 five and circulating water five. The water-containing material discharged from the discharge pipe 12 is filtered by the filter unit 13 to obtain product six and circulating water six. The second interference unit 2 further sorts and dechlorinates the high-specific gravity materials, which not only improves the sorting effect but also prolongs the immersion contact time between the high-specific gravity materials and water, thereby improving the dechlorination effect and further reducing the chlorine content in the coal.

[0045] The third interference unit 2 is started, and product one is transported to the third interference unit 2, where it is sorted and dechlorinated again. After sorting by 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. The third interference unit 2 is used to sort and dechlorinate the material with a smaller specific gravity again, preventing the material with a larger specific gravity from accidentally entering product one. While improving the sorting effect, the material with a smaller specific gravity is again immersed in water, thereby improving the dechlorination effect and further reducing the chlorine content in the coal.

[0046] The third step is the use of circulating water. The original water flow is first transported to the second and third interference units 2. With the help of the difference in chlorine content between water and materials, product one and product two with lower chlorine content are subjected to secondary sorting and secondary dechlorination, and then circulating water three, circulating water four, circulating water five and circulating water six with a certain chlorine content are obtained. One or more of them are mixed to obtain a liquid, which is used as the original water flow of the first interference unit 2 and enters the interference chamber 4 of the first interference unit 2 to sort and dechlorinate the original material with the highest chlorine content; with the help of the difference in chlorine concentration in the circulating water, the utilization rate of the circulating water is improved, and at the same time, the consistency of the sorting effect of the interference unit 2 is improved.

[0047] The fourth step is the recycling of the circulating water. The circulating water five and the circulating water six are passed into the purification treatment device. The purification treatment device is preferably a device in the prior art that can filter and treat chlorine-containing water, such as the reverse osmosis membrane in the prior art, or a purification treatment device that uses chemical changes to treat chlorine; if the process involves adjusting the chlorine concentration in the circulating water, any one or more of the circulating water three, circulating water four, circulating water five and circulating water six can be selected and put into the circulating water five and circulating water six to adjust the chlorine concentration. Finally, the mixed circulating water is passed into the purification treatment device for purification. The purified circulating water is again put into the second and third interference units 2 for recycling to improve the water utilization rate. At the same time, an appropriate amount of original water is appropriately supplemented to offset the natural loss of the circulating water during the circulation process.

[0048] This process combines coal washing and dechlorination, improving both separation and dechlorination efficiency while reducing water loss. Furthermore, the modification of existing equipment is minimal, allowing for direct retrofit and optimization of existing coal washing plants. This overall process simplifies equipment modification and improves overall efficiency. It also reduces the floor space occupied by separate coal dechlorination operations, increasing plant utilization.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
