However, due to the heat exchange between the liquid slag layer and the wall of the gasifier, when the temperature drops below the liquidus line, the coal ash slag is prone to phase change behaviors such as crystallization, which in turn causes the viscosity of the coal ash slag to increase, affecting the fluidity of the coal ash slag in the gasifier. Therefore, how to improve the slag discharge flow characteristics of the coal ash slag in the gasifier is an urgent problem that needs to be solved. Summary of the invention

[0018] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0019] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0020] It should be noted that in the technical solution of this application, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are all carried out with the user's consent, and are in compliance with relevant laws and regulations and do not violate public order and good morals.

[0021] The following describes the coal ash slag processing method, device, electronic device and storage medium of the embodiments of the present application with reference to the accompanying drawings.

[0022] It should be noted that the executor of the coal ash slag treatment method of this embodiment is a coal ash slag treatment device, which can be implemented by software and / or hardware and can be configured in an electronic device.

[0023] Figure 1 A schematic flow chart of a method for treating coal ash slag provided in the first embodiment of the present application.

[0024] like Figure 1 As shown, the coal ash slag treatment method comprises the following steps:

[0025] Step 101, obtaining the coal ash slag to be processed, and detecting whether the coal ash slag is crystalline slag.

[0026] The coal ash slag to be treated may refer to the ash slag formed after the coal undergoes high-temperature physical and chemical reactions in the gasifier.

[0027] As an example, a multivariate phase diagram is drawn based on a thermodynamic database matching the composition of coal ash slag, wherein the multivariate phase diagram includes multiple primary crystal phase regions, each of which corresponds to a primary crystal projection region; a representative ash sample in any primary crystal projection region is used as the coal ash slag to be processed. For example, the composition of coal ash slag includes elements such as iron, silicon, calcium, magnesium, aluminum, and sodium, and a multivariate phase diagram can be drawn based on the aforementioned elements.

[0028] Among them, the fluidity of the crystallized slag in the gasifier is relatively poor. Therefore, after obtaining the coal ash slag, it is possible to first detect whether the coal ash slag is crystallized slag, and then determine whether the fluidity of the coal ash slag needs to be improved.

[0029] As an example, the content of each component in the coal ash slag can be understood through chemical composition analysis, and the type of the coal ash slag can be determined based on the content and proportion of these components, that is, whether the coal ash slag is crystalline slag.

[0030] Step 102, when the coal ash slag is crystalline slag, obtain the initial addition amount of the regulating and controlling auxiliary agent, where the regulating and controlling auxiliary agent is used to convert the coal ash slag from crystalline slag to glass slag.

[0031] Among them, the regulating agent can be used to change the phase region of the coal ash slag in the multivariate phase diagram. For example, the regulating agent can refer to silicon dioxide (SiO2). With the addition of the regulating agent, the content of certain components in the coal ash slag changes. These changes may cause the movement of the phase region boundary, so that the coal ash slag originally in the crystalline slag phase region enters the glass slag phase region.

[0032] As an example, the content of each component in the coal ash slag can be obtained, and the initial addition amount of the regulating additive can be determined based on the content of each component in the coal ash slag. For example, the content of each component in the coal ash slag can be input into the target model for outputting the initial addition amount of the regulating additive to obtain the initial addition amount corresponding to the coal ash slag. The target model can refer to a neural network model or a mathematical model.

[0033] As another example, the content of each component in the coal ash slag can be obtained, and the initial addition amount of the regulating auxiliary agent can be determined based on the set process temperature and the content of each component in the coal ash slag.

[0034] It should be noted that, for the same coal ash slag, at different set process temperatures, the corresponding initial addition amounts may be the same or different.

[0035] Step 103 , heating the coal ash slag to a set process temperature, adding a regulating auxiliary agent based on an initial addition amount, and detecting the viscosity of the coal ash slag after adding the regulating auxiliary agent.

[0036] In the embodiment of the present application, the set process temperature may refer to any temperature within the process temperature range of fluidized bed gasification, wherein the process temperature range of fluidized bed gasification may be [1200° C., 1250° C.].

[0037] Adding regulating additives to the coal ash slag based on the initial addition amount can make the coal ash slag in the crystalline slag phase zone enter the glass slag phase zone, but the viscosity of the coal ash slag after adding the regulating additives may not meet the set viscosity requirements, and viscosity is also a key factor affecting the fluidity of slag discharge. Therefore, the present application also performs viscosity detection after adding the regulating additives. Specifically, after heating the coal ash slag to the set process temperature, maintain a constant temperature, and after adding the initial amount of regulating additives, the viscosity of the coal ash slag is detected by a high-temperature molybdenum rotor.

[0038] Step 104, when the viscosity of the coal ash slag does not meet the set viscosity requirement, continuously add a regulating auxiliary agent to the coal ash slag until the viscosity of the coal ash slag meets the set viscosity requirement.

[0039] The setting viscosity requirement may refer to a specific viscosity, such as 5 Pascal seconds (Pa·s) or 25 Pa·s, or may refer to a viscosity range. Continuously adding a regulating agent to the coal ash slag may be understood as adding a regulating agent to the coal ash slag in small amounts and multiple times. It should be noted that when continuously adding a regulating agent, the amount of the regulating agent added needs to be recorded.

[0040] Step 105: determining a target addition amount of the regulating auxiliary agent based on the initial addition amount and the continuous addition amount.

[0041] Among them, the sum of the initial addition amount and the continuous addition amount can be used as the target addition amount.

[0042] It should be noted that the composition of the coal ash slag to be treated, the set process temperature, and the set viscosity requirements will all affect the amount of control additive added. If any of the three changes, the corresponding target addition amount will also change.

[0043] For example, for coal ash slag A, when the process temperature is set to 1200°C and the viscosity requirement is set to 5 Pa·s, the corresponding target amount of regulating additive is L1; when the process temperature is set to 1250°C and the viscosity requirement is set to 5 Pa·s, the corresponding target amount of regulating additive is L2; ​​when the process temperature is set to 1200°C and the viscosity requirement is set to 15 Pa·s, the corresponding target amount of regulating additive is L3; among them, L1, L2 and L3 are not the same.

[0044] In an optional embodiment, when the viscosity of the coal ash slag meets the set viscosity requirement, the initial addition amount is used as the target addition amount.

[0045] After obtaining the target addition amount, for the same coal ash slag, the regulating additive can be directly added to the coal ash slag according to the target addition amount, so as to convert the coal ash slag from crystalline slag to glass slag with a viscosity that meets the set viscosity requirements, thereby improving the slag discharge flow characteristics of the coal ash slag in the gasifier. In addition, since the present application can modify the coal ash slag by regulating the additive for coal ash slag with different original mineral compositions so that it can be discharged smoothly from the gasifier, the present application also broadens the scope of application of raw coal types in the entrained bed gasification process.

[0046] In summary, the present application obtains the coal ash slag to be processed, and detects whether the coal ash slag is crystallized slag; when the coal ash slag is crystallized slag, obtains the initial addition amount of the regulating aid, and the regulating aid is used to convert the coal ash slag from crystallized slag to glass slag; heats the coal ash slag to a set process temperature, and adds the regulating aid based on the initial addition amount, and detects the viscosity of the coal ash slag after adding the regulating aid; when the viscosity of the coal ash slag does not meet the set viscosity requirement, continuously add the regulating aid to the coal ash slag until the viscosity of the coal ash slag meets the set viscosity requirement; based on the initial addition amount and the continuous addition amount, determine the target addition amount of the regulating aid. The target addition amount of the regulating aid determined by the aforementioned steps can not only ensure the vitrification of the crystallized slag, but also ensure that the viscosity of the coal ash slag is within the operating window of the liquid slag discharge, so as to achieve the purpose of improving the slag discharge flow characteristics of the coal ash slag in the gasifier.

[0047] Figure 2 A schematic flow chart of a method for treating coal ash slag provided in the second embodiment of the present application.

[0048] like Figure 2 As shown, the coal ash slag treatment method may include the following steps:

[0049] Step 201, obtaining the coal ash slag to be processed.

[0050] Step 202, obtain a set mass of coal ash slag, a reference precipitation mass of primary phase crystals during cooling from a first temperature to a second temperature, and obtain the ratio of the reference precipitation mass to the set mass; wherein the first temperature is the temperature at which the coal ash slag begins to enter a liquid phase.

[0051] The set mass may refer to a preset coal ash slag mass. As an example, the set mass may be denoted as M x ; The first temperature may refer to the intersection temperature of the initial composition point of the coal ash slag in the multivariate phase diagram and the liquid phase surface; The difference between the first temperature and the second temperature is the set temperature difference, for example, the set temperature difference may be 100°C; As an example, the reference precipitation mass may be recorded as m x , the ratio of the reference precipitation mass to the set mass m x / Mx , which is used to indicate the mass proportion of crystals precipitated during the cooling process.

[0052] As an example, obtaining a reference precipitation mass of primary phase crystals of a set mass of coal ash slag during cooling from a first temperature to a second temperature includes: drawing a multivariate phase diagram based on a thermodynamic database matching the composition of the coal ash slag; connecting the primary phase pure composition points corresponding to the coal ash slag and the initial composition points of the coal ash slag in the multivariate phase diagram to obtain a first connecting line; and determining the reference precipitation mass based on the first connecting line and the isothermal liquidus corresponding to the first temperature through the lever rule.

[0053] Among them, the primary phase pure composition point usually refers to the first precipitated crystal phase with pure or nearly pure composition when the coal ash slag begins to crystallize. This point is usually located at a certain position in the primary phase region on the multivariate phase diagram, representing the stable composition of the crystal phase at a specific temperature. The initial composition point refers to the original composition of the coal ash slag before it begins to crystallize, that is, the initial chemical composition of the coal ash slag. This point is usually represented as a point on the multivariate phase diagram, located at a certain position in the multivariate phase diagram, representing the chemical composition of the coal ash slag.

[0054] Step 203, adding a set mass of coal ash slag into the furnace and heating it to a first temperature, and after a set time interval, adding primary phase crystals into the furnace according to a reference precipitation mass.

[0055] After heating to the first temperature, the furnace can be kept warm. After the set time, m x As an example and not a limitation, the set time length may be 30 minutes.

[0056] Step 204, determining the melting rate of the primary phase crystals according to the mass change of the primary phase crystals in the furnace.

[0057] Among them, the melting rate of the primary phase crystals indicates the ratio or rate of reduction of the crystal mass per unit time. After adding the primary phase crystals, under the first constant temperature and the reaction driving force of 100°C temperature difference, molybdenum wire sampling is performed every 30 seconds to monitor the change of the crystal mass in the furnace over time, and then the melting rate of the primary phase crystals is calculated according to the mass change of the primary phase crystals. It should be noted that the melting rate of the primary phase crystals can also refer to the average melting rate of the primary phase crystals.

[0058] As an example, V x =(m x -m' x \) / (m x *t), calculate the melting rate of the primary phase crystal, where V x Indicates the melting rate, m'x It indicates the mass of crystals in the furnace after t minutes (min).

[0059] Step 205, based on the comparison result of the ratio with the set ratio threshold value, and the comparison result of the melting speed with the set melting speed threshold value, it is detected whether the coal ash slag is crystallized slag.

[0060] Among them, whether the coal ash slag is crystalline slag is detected based on the relationship between the ratio and the set ratio threshold, and the relationship between the melting rate and the set melting rate threshold.

[0061] As an example, when the ratio is greater than a set ratio threshold and the melting rate is greater than a set melting rate threshold, the coal ash slag is determined to be crystallized slag. The set ratio threshold may be 20%, and the set melting rate threshold may be 40% / min.

[0062] As another example, when the ratio is less than or equal to a set ratio threshold, or the melting rate is less than or equal to a set melting rate threshold, it is determined that the coal ash slag is not crystalline slag.

[0063] Step 206, when the coal ash slag is crystalline slag, obtain the initial addition amount of the regulating auxiliary agent, the regulating auxiliary agent is used to convert the coal ash slag from crystalline slag to glass slag.

[0064] As an example, a multivariate phase diagram is drawn based on a thermodynamic database that matches the composition of coal ash slag; based on the initial composition points of the coal ash slag and the regulating additive in the multivariate phase diagram, lines are connected to obtain a second line; based on the multivariate phase diagram, in the primary crystal phase region of the regulating additive, an isothermal liquidus line corresponding to the set process temperature is obtained; through the lever rule, based on the second line and the isothermal liquidus line, the initial addition amount of the regulating additive is determined.

[0065] The initial composition point of the control agent in the multi-element phase diagram may refer to the SiO2 angle, and the primary crystal phase region of the control agent may refer to the silicate primary crystal phase region. When determining the initial addition amount, move along the second connecting line to the boundary of the silicate primary crystal phase region and the isothermal liquidus line corresponding to the set process temperature in the phase region, and calculate the initial addition amount of the control agent by the lever rule.

[0066] Step 207 , heating the coal ash slag to a set process temperature, adding a regulating auxiliary agent based on an initial addition amount, and detecting the viscosity of the coal ash slag after adding the regulating auxiliary agent.

[0067] Step 208, when the viscosity of the coal ash slag does not meet the set viscosity requirement, continuously add a regulating auxiliary agent to the coal ash slag until the viscosity of the coal ash slag meets the set viscosity requirement.

[0068] As an example, after continuously adding regulating additives to the coal ash slag until the viscosity of the coal ash slag meets the set viscosity requirements, the method also includes: obtaining the liquidus surface temperature of the coal ash slag corresponding to the target amount of regulating additives added; and storing the coal ash slag to be processed, the set process temperature, the target amount added, the set viscosity requirements and the liquidus surface temperature in an associated manner.

[0069] Among them, the liquidus surface temperature can be understood as the temperature at which the coal ash slag with the addition of regulating additives just begins to precipitate crystals. Specifically, the coal ash slag with the target amount of regulating additives is cooled and the crystal precipitation is monitored to determine the liquidus surface temperature.

[0070] Based on the above steps, the target addition amount of the regulating additive and the liquidus surface temperature corresponding to the coal ash slag of different compositions under different set process temperatures and different set viscosity requirements can be obtained, and these correspondences are stored to obtain a correspondence table. In the case where the flow characteristics of the coal ash slag need to be improved in the future, the target addition amount of the regulating additive corresponding to the coal ash slag under specific conditions can be obtained based on the correspondence table.

[0071] Step 209: Determine the target addition amount of the regulating auxiliary agent based on the initial addition amount and the continuous addition amount.

[0072] It should be noted that the execution process of step 201 and step 207-step 209 can be implemented in any way in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0073] In summary, the present application obtains a set mass of coal ash slag, a reference precipitation mass of primary phase crystals in the process of cooling from a first temperature to a second temperature, and obtains the ratio of the reference precipitation mass to the set mass; wherein the first temperature is the temperature at which the coal ash slag begins to enter the liquid phase; a set mass of coal ash slag is added to the furnace and heated to the first temperature, and after a set interval, primary phase crystals are added to the furnace according to the reference precipitation mass; according to the mass change of the primary phase crystals in the furnace, the melting rate of the primary phase crystals is determined; according to the comparison result of the ratio with the set ratio threshold value, and the comparison result of the melting rate with the set melting rate threshold value, it is detected whether the coal ash slag is crystalline slag. The proportion of crystal precipitation mass and the melting rate are important factors in determining whether the coal ash slag is crystalline slag. Therefore, based on the comparison result of the proportion of crystal precipitation mass and the melting rate with the corresponding threshold value, it is possible to accurately determine whether the coal ash slag is crystalline slag.

[0074] In order to implement the above-mentioned embodiments, the third embodiment of the present application further proposes a coal ash slag processing device.
