In the production process of rock wool, some short fiber waste, slag balls, scraps, trimmings and packaging waste will be generated. Among them, scraps, trimmings and packaging waste need to be incinerated. When the waste is put into the incinerator for incineration, due to the different types, materials, volumes and other factors of the waste, the incineration parameters of the waste in the incinerator are uneven, which affects the incineration efficiency and the mixed incineration is prone to produce polluting gases.

[0031] In view of this, the present application provides an incineration treatment method for an incinerator.

In order to ensure that the waste to be incinerated in the subsequent first combustion unit is evenly distributed, and the first height of the waste to be incinerated obtained is the closest to the actual situation, the uniformity of the waste to be incinerated in the target feeding unit is adjusted, and finally the target combustion unit is determined according to the first height, the current waste height stored in the first combustion unit in the non-working state in the target first combustion chamber, and the preset height range, so that the amount of waste put into the target combustion unit can not only make full use of the combustion space, but also ensure a good combustion effect within a suitable height range, avoiding the influence of too much or too little waste on the combustion efficiency and quality. This scheme can improve the combustion efficiency, optimize resource utilization and improve the reliability and sustainability of incineration treatment.

[0032] It should be noted that the above-mentioned application scenario of the rock wool production line is only one of the application scenarios of the incinerator incineration treatment method provided in the embodiment of the present application.

Here, the conveying component 11 is, for example, a conveyor belt structure, and the conveying component 11 has a feed end, a first discharge end, and a second discharge end.

The passable area formed by the screening frame 12 is adjusted by the first driving member, the second driving member and the third driving member, so as to achieve the purpose of screening waste materials of different volumes and transmitting them to different discharge ends.

[0034] The auxiliary pushing assembly 13 is used to push the waste materials with a single volume greater than or equal to a preset volume value at the screening frame 12 to the second discharge end; the first discharge end is used to send the waste materials to the first combustion station 20, and the second discharge end is used to send the waste materials to the second combustion station 30. The auxiliary pushing assembly 13 at least includes a driving structure and a push plate arranged at the driving end of the driving structure, and its pushing direction is toward the second discharge end.

[0035] The first combustion station 20 is provided with a plurality of first combustion chambers for burning different types of waste and a feeding unit 21 used in conjunction therewith. The first combustion chamber includes a plurality of first combustion units 22, for example, Figure 7 As shown, the first combustion chamber a includes six first combustion units 22; a first detection module 23 is installed on the feeding unit 21, which is used to detect the first height of the waste to be incinerated in the feeding unit 21; the first combustion unit 22 is used to receive the waste to be incinerated delivered by the feeding unit 21 and incinerate it; here, the bottom area of ​​the feeding unit 21 is equal to the bottom area of ​​the first combustion unit 22 used in conjunction with it.

[0036] A second combustion station 30, the second combustion station 30 has a second combustion chamber, the second combustion chamber includes a plurality of second combustion units 31; the number of the second combustion units 31 is equal to the number of waste types; the second combustion chamber is used to receive the waste output from the second discharge end and incinerate it; The control mechanism 40 is in communication with the feed unit 10, the first combustion station 20 and the second combustion station 30, and is used to control the actions of corresponding components to perform an incineration process.

[0037] The control mechanism 40 includes: a processing module 41, a display module 42 and an image acquisition module 43. The processing module 41 is used to control the device connected to it for communication to perform corresponding actions; the display module 42 is used to display the current data of the system and the operating status of the device; the image acquisition module 43 is used to capture a first image, which is an image of the waste currently being transported by the feeding unit.

[0039] In order to make the incineration treatment method provided by the incinerator in the embodiment of the present application clearer and easier to understand, the method is introduced below with reference to the accompanying drawings. Figure 1 As shown, this figure is a flow chart of the incineration treatment method of the incinerator provided in the embodiment of the present application, and the method includes: S1. According to the individual volume of the waste currently conveyed by the feeding unit, the waste to be incinerated is screened from the waste currently conveyed by the feeding unit.

[0040] It should be noted that the single volume of the waste currently transported by the feeding unit can be determined based on the required specifications of the actual products in the production line and the size of the raw materials. The image acquisition module can also be used to photograph the waste currently transported to obtain a first image, and the first image can be transmitted to the processing module. The processing module identifies the waste contour in the first image to obtain the single volume of the waste currently transported.

[0041] The method of screening the waste to be incinerated from the waste in the feeding unit is: using the above-mentioned screening component to perform the screening operation, specifically, first adjusting the passable area formed by the screening frame according to the preset volume value, if the waste on the feeding unit can pass through the passable area, it means that the volume of the current waste is less than the preset volume value, and it can be used as the waste to be incinerated. Here, the preset volume value is set according to actual needs.

[0042] Furthermore, the method further comprises the following steps: The waste materials in the feeding unit whose single volume is greater than or equal to the preset volume value are screened, and transported to the second combustion unit corresponding to the second combustion station according to the type of waste materials; the number of second combustion units is equal to the number of waste types.

[0043] Among them, the classification standard of waste types can be divided according to the constituent materials, or according to the different processing steps in the production line. This scheme divides the waste generated by different processing steps in the production line. For example, in the stretching process of glass wool fibers, some defective products with uneven fiber thickness, breakage, etc. will appear. These defective products are cut off and defined as defective waste; in the cutting process of glass wool fibers, it is necessary to cut sub-semi-finished products of standard specifications from the raw materials, and the remaining part of the raw materials after cutting is defined as scraps; in the molding process of glass wool fibers, in order to obtain products that meet quality requirements, it is necessary to trim the sub-semi-finished products, and the trimmed edge materials are defined as trimming waste.

[0044] The second combustion station is provided with second combustion units having the same number as the types of waste materials, and each second combustion unit is used for incinerating waste materials of one type of waste materials.

[0045] In addition, if Figure 2 As shown, after screening the waste materials with a single volume greater than or equal to the preset volume value in the feeding unit, before transporting the waste materials to the second combustion unit corresponding to the second combustion station, the following steps are also included: S101 , identifying the waste type and waste size of a single waste with a volume greater than or equal to a preset volume value.

[0046] Similarly, the method for screening out waste materials with a single volume greater than or equal to a preset volume value in the waste materials of the feeding unit is: using the above-mentioned screening component to perform screening operations, specifically, first adjusting the passable area formed by the screening frame according to the preset volume value. If the waste materials on the feeding unit cannot pass through the passable area, it means that the single volume of the current waste materials is greater than or equal to the preset volume value, and it is necessary to use an auxiliary pushing component to push it to the second combustion unit corresponding to the second combustion station.

[0047] Here, the type of waste can be determined by the processing step of the production line from which the waste comes. The size of the waste can be acquired by the image acquisition module, or can be determined based on the required specifications of the actual product in the production line and the size of the raw material.

[0048] S102, calling a parts processing database, and searching the parts processing database for a material type corresponding to the waste material type, to obtain processing specifications of parts corresponding to the material type; the parts processing database includes at least a plurality of material types and corresponding parts and processing specifications.

[0049] The parts processing database is shown in Table 1. The material types in Table 1 are divided according to the different constituent materials of the parts. It can be understood that the constituent material of a part is a material type; the processing specifications in Table 1 refer to the standard length, width and thickness of the parts. "#001", "#002" and the like in Table 1 represent different parts, "A1", "A2" and the like represent the material types of different parts, and "J1", "J2" and the like represent the processing specifications of different parts. For example, the waste type of a single waste material with a volume greater than or equal to the preset volume value corresponds to the material type of #001, and the corresponding processing specification is J1. It should be noted that a waste type corresponds to a material type, and the material types of different parts can be the same, that is, the same material type can correspond to multiple parts, that is, one waste material can be used to make multiple parts.

[0050] Table 1 Parts processing database

[0051] S103. Determine the number of parts that can be processed based on the scrap size and processing specifications.

[0052] Here, the waste size refers to the length, width and height of the waste whose volume is greater than or equal to the preset volume value. The processing specification can be the processing specification of all parts corresponding to the waste type. The processing module is used to calculate the number of processable parts on the current waste. The number of processable parts refers to the number of all parts manufactured according to the processing specifications.

[0053] S104: If the number of machinable parts is greater than a set threshold, the current volume of waste is put into a storage unit as recyclable waste.

[0054] Here, the threshold value can be set according to actual needs. If the number of machinable parts is greater than the threshold value, it means that the current waste can be reused, and the current waste can be put into the storage unit; the storage unit is used to store the waste that can be reused.

[0055] In addition, after executing the above steps S101-S103, if the number of machinable parts is less than or equal to the set threshold, it indicates that the current volume of waste cannot be reused, and it is put into the corresponding second combustion unit, wherein the combustion parameters of each second combustion unit are obtained in the parameter database according to the waste type, as shown in Table 2, the parameter database includes a variety of waste types and corresponding combustion parameters, and the combustion parameters include at least: combustion temperature, ventilation volume and combustion time; when the second detection module at the side wall of the second combustion unit identifies the waste, it indicates that the accumulated waste in the current second combustion unit has reached the incineration level, and at this time, the processing module controls the current second combustion unit to perform incineration according to the corresponding combustion parameters.

[0056] It should be noted that "F1", "F2" and the like in Table 2 represent different types of waste, the values ​​of combustion temperature and ventilation volume in Table 2 are only for illustrative purposes, and "C1", "C2" and the like in Table 2 represent the duration of complete combustion corresponding to different types of waste. Since the combustion duration is affected by the combustion temperature, ventilation volume, waste density and waste shape, the combustion duration in the parameter database can be set based on experience, or it can be obtained based on theoretical calculations and then fine-tuned through experiments to ensure the quality and efficiency of waste combustion, while avoiding the generation of harmful substances during combustion.

[0057] Table 2 Parameter database

[0058] Here, when the second combustion unit is not performing the incineration operation, it is in a low-temperature preheating mode, which can be used to dry the waste material put into it and remove moisture from the waste material to reduce the impact of moisture on the combustion process.

[0059] S2. Select a target first combustion chamber according to the waste type of the waste to be incinerated, and transport the waste to be incinerated to a target feeding unit corresponding to the target first combustion chamber.

[0060] It should be noted that the waste is classified through the pre-screening method of step S1, and then the target first combustion chamber is selected according to the waste type of the waste to be incinerated. The waste type of the waste to be incinerated can be obtained from the processing procedure that generates the waste in the production line, and the waste to be incinerated is put into the target feeding unit corresponding to the target first combustion chamber.

[0061] S3. Adjust the uniformity of the waste to be incinerated in the target feeding unit, and obtain the first height of the waste to be incinerated and the height of the waste currently stored in the first combustion unit in the target first combustion chamber which is in a non-working state.

[0062] It should be noted that when the target feeding unit has accepted the waste to be incinerated, the vibration component of the target feeding unit needs to be started to distribute the waste to be incinerated as evenly as possible in the target feeding unit, so that the first height collected later is closest to the actual situation; the first height of the waste to be incinerated can be detected by the first detection module on the target feeding unit, where the first detection module is, for example, an infrared detector, and the height of the waste currently stored in the non-working first combustion unit in the target first combustion chamber refers to the cumulative height of the waste to be incinerated put into the same non-working first combustion unit. Here, the vibration component of the target feeding unit is of conventional design and will not be described in detail.

[0063] In addition, the first combustion unit being in a non-operating state means that the first combustion unit is not currently performing an incineration operation. Similarly, when the first combustion unit is not performing an incineration operation, it is in a low-temperature preheating mode, which can be used to dry the waste material put into it and remove moisture from the waste material to reduce the impact of moisture on the combustion process.

[0064] S4. Determine a target combustion unit according to the first height, the current height of the waste stored in the first combustion unit in a non-working state, and a preset height range; the target combustion unit is the first combustion unit in the target first combustion chamber in a non-working state and the sum of the current height of the waste stored and the first height is within the preset height range and is the maximum value.

[0065] Here, the preset altitude range is a altitude range set under the premise of ensuring combustion efficiency and safety, and its endpoint values ​​can be set according to actual conditions.

[0066] For example, the first combustion unit a, the first combustion unit b, and the first combustion unit c are in a non-working state, the current height of the waste stored in the first combustion unit a is 1.2 meters, the current height of the waste stored in the first combustion unit b is 1.5 meters, and the current height of the waste stored in the first combustion unit c is 1 meter. Assuming that the preset height range is 1.5-2.5 meters and the first height is 0.8 meters, then the sum of the current height of the waste stored in the first combustion unit a and the first height is 2 meters, the sum of the current height of the waste stored in the first combustion unit b and the first height is 2.3 meters, and the sum of the current height of the waste stored in the first combustion unit c and the first height is 1.8 meters; among them, 2.3 meters and 1.8 meters are within the preset height range, and 2.3 meters is the maximum value, so the first combustion unit c is selected as the target combustion unit, so that determining the target combustion unit can fully utilize the space of the combustion unit while ensuring that it is within the preset height range for safe and efficient combustion.

[0067] The above content is only an example of selecting a target combustion unit. In actual situations, a first combustion chamber includes a large number of first combustion units, and the first combustion unit that meets the conditions is not unique. The following describes possible situations.

[0068] like Figure 3 As shown, the target combustion unit is determined according to the following steps: S401. When the first height is within a preset height range, the first combustion unit in the target first combustion chamber that is in a non-working state and currently has a waste storage height of zero is screened, and multiple first distances are calculated based on the position of the first combustion unit and the current position of the target feeding unit.

[0069] It should be noted that if there is no first combustion unit in a non-working state and with a current waste storage height of zero in the target first combustion chamber, then a first combustion unit in a non-working state and with a minimum current waste storage height is obtained, and the height sum is calculated based on the current waste storage height and the first height of the current first combustion unit. If the height sum is within the preset height range, the current first combustion unit is used as the target combustion unit. If the height sum exceeds the preset height range, the first combustion unit that completes the incineration operation in the first combustion units in the working state in the target first combustion chamber can be waited for as the target combustion unit, or the target combustion unit can be selected according to steps S405-S407.

[0070] S402. Select the first combustion unit with the smallest first distance as the target combustion unit.

[0071] It should be noted that the first height being within the preset height range indicates that the current waste to be incinerated is suitable for being placed in a first combustion unit that is in a non-working state and does not store any waste to be incinerated for incineration treatment; the first combustion unit that is in a non-working state and does not store any waste to be incinerated refers to an idle and completely empty first combustion unit.

[0072] If there is only one first combustion unit that is not in operation and does not store waste to be incinerated, it will be directly used as the target combustion unit, and the current waste to be incinerated will be placed in it for incineration.

[0073] If the number of first combustion units that are not in operation and do not store waste to be incinerated is at least two, multiple first distances are calculated based on the positions of these first combustion units and the current position of the target feeding unit. Here, the method for calculating the first distance is, for example, to construct a three-dimensional coordinate system in the incineration treatment system of the incinerator, obtain the first coordinates of the center position of the first combustion unit that is not in operation and does not store waste to be incinerated, and the second coordinates of the center position of the target feeding unit in the three-dimensional coordinate system, and multiple first distances can be calculated based on the first coordinates and the second coordinates.

[0074] After obtaining multiple first distances, the first combustion unit with the smallest first distance is selected as the target combustion unit. The purpose of selecting the target combustion unit is to minimize the loss, time cost and energy consumption of the waste during transportation, and select the idle and suitable combustion unit closest to the target feeding unit to receive the waste, thereby improving the efficiency of the entire waste incineration process.

[0075] like Figure 4 As shown, the target combustion unit is determined according to the following steps: S403: When the first height is less than the minimum value of the preset height range, the sum of the height of the waste currently stored in the first combustion unit in a non-working state in the target first combustion chamber and the first height is calculated to obtain a plurality of heights to be accumulated.

[0076] S404, selecting the first combustion unit corresponding to the maximum value of the to-be-accumulated height that is within the preset height range as the target combustion unit.

[0077] It should be noted that the first height is less than the minimum value of the preset height range, indicating that the current waste to be incinerated cannot be directly incinerated separately. The height of the waste currently stored in the first combustion unit in the non-working state in the target first combustion chamber is obtained, and its sum with the first height is calculated to obtain multiple heights to be accumulated. Among these heights to be accumulated, the first combustion unit corresponding to the maximum accumulated height within the preset height range is selected as the target combustion unit. The purpose of selecting the target combustion unit is to make full use of the space of the first combustion unit, store as much waste as possible within the appropriate range, improve the use efficiency of the first combustion unit, and reduce the number and cost of waste treatment.

[0078] like Figure 5 As shown, the target combustion unit is determined according to the following steps: S405. When the first height is greater than the maximum value of the preset height range, the first combustion unit in the target first combustion chamber which is in a non-working state and has the smallest height of waste currently stored is selected as a spare combustion unit.

[0079] S406, delivering the waste to be incinerated in the target feeding unit to the standby combustion unit according to the preset delivery time.

[0080] S407, screening the second height and the sum of the height of the waste currently stored in the first combustion unit in a non-working state in the target first combustion chamber, and the first combustion unit that is within the preset height range and has the maximum value is taken as the target combustion unit; the second height is the height of the waste remaining to be incinerated after the target feeding unit is put into place.

[0081] It should be noted that the first height being greater than the maximum value of the preset height range indicates that the amount of waste to be incinerated is relatively large, and a suitable target combustion unit cannot be selected for it according to the above process, and special treatment is required.

[0082] The selection criteria for the spare combustion unit is: select the first combustion unit in the target first combustion chamber that is in a non-working state and has the smallest height of waste stored currently as the spare combustion unit. The first combustion unit with the smallest height of waste stored currently is selected so that when waste is subsequently placed, there will be relatively more space to accommodate this large batch of waste to be incinerated, so as to minimize the problems that may be caused by insufficient space.

[0083] The preset delivery time is set according to the actual situation. The preset delivery time is used to control the process of the target feeding unit delivering waste to the spare combustion unit. By setting the delivery time, the waste to be incinerated can be transported to the spare combustion unit more evenly and orderly, avoiding various problems caused by too fast or too slow delivery speed. For example, too fast may cause excessive instantaneous pressure in the spare combustion unit, and too slow may affect the overall waste treatment efficiency. Moreover, within this preset delivery time, the feeding unit continues to deliver the waste to be incinerated to the spare combustion unit, so that part of the waste can be initially processed and placed.

[0084] After the waste to be incinerated is delivered to the standby combustion unit according to the preset delivery time, there will still be residual waste to be incinerated in the target feeding unit, and the current height of the residual waste is the second height.

[0085] After the waste to be incinerated is placed in the spare combustion unit, the target combustion unit is determined based on the second height and the height of the waste currently stored in the first combustion unit in the non-working state in the target first combustion chamber and the preset height range. The selection method at this time is the same as the screening step after comparing the first height and the preset height range, that is, the sum of the height of the waste currently stored in each non-working combustion unit and the second height is calculated, and then the first combustion units within the preset height range are screened out, and finally, among these first combustion units that meet the preset height range, the first combustion unit with the maximum height sum is selected as the target combustion unit. This selection method is to make full use of the space of the first combustion unit, while ensuring that the remaining waste to be incinerated is processed within the preset height range for safe and efficient combustion.

[0086] Through the above steps S405-S407, the situation where the first height of the waste to be incinerated is greater than the maximum value of the preset height range can be effectively handled, and the combustion unit resources can be reasonably utilized to ensure the efficiency and safety of the entire waste incineration process.

[0087] In addition, if Figure 6 As shown, the method also includes the following steps: S408. Determine a third height of the waste to be incinerated that is sent to the backup combustion unit based on the first height and the second height.

[0088] S409, determining a fourth height of the current spare combustion unit according to the third height and the height of the waste stored before the waste to be incinerated is placed in the spare combustion unit.

[0089] S410: If the fourth height is less than the minimum value of the preset height range, the fourth height is updated to the height of the waste currently stored in the standby combustion unit.

[0090] S411. If the fourth height is within the preset height range, the current standby combustion unit is controlled to perform an incineration operation.

[0091] It should be noted that the third height is the difference between the first height and the second height. The fourth height is the sum of the height of the waste stored before the waste to be incinerated is placed in the spare combustion unit and the third height, that is, the total waste accumulation height in the spare combustion unit after this placement operation.

[0092] When the fourth height is less than the minimum value of the preset height range, it means that after this delivery operation, the waste height in the standby combustion unit is still too low and does not meet the requirements for direct incineration. At this time, the fourth height is updated to the current height of the waste stored in the standby combustion unit, and the incineration operation is started after waiting for waste of a suitable height to be delivered again.

[0093] When the fourth height is within the preset height range, it means that after this placement operation, the height of the waste in the standby combustion unit is appropriate, and it will not cause problems such as incomplete combustion due to being too low, nor will it cause safety hazards due to being too high. At this time, the current standby combustion unit can be controlled to perform the incineration operation, that is, the standby combustion unit can be controlled to incinerate the internal waste according to its normal work flow to achieve effective treatment of the incinerated waste.

[0094] S5. The waste materials to be incinerated in the target feeding unit are transported to the target combustion unit for incineration.

[0095] Through the above steps, the waste to be incinerated is transported to the target combustion unit for incineration treatment, thereby achieving efficient treatment of the waste and reducing environmental pollution.

[0096] Furthermore, the method further comprises the following steps: Obtaining the number of combustions and the degree of combustion of the first combustion unit, and determining the burnout ratio according to the number of combustions and the degree of combustion corresponding to each combustion; the burnout ratio is the ratio of the number of combustions to the number of combustions; When the burnout ratio is less than the first ratio, the current first combustion unit is shut down and repaired.

[0097] It should be noted that the number of incinerations refers to the cumulative number of times the first combustion unit performs combustion operations on the waste to be incinerated; each time the first combustion unit starts and completes a complete combustion process, the number of incinerations is accumulated once. Here, the number of incinerations can be recorded by the counter of the first combustion unit, and the processing module can directly call the data.

[0098] The degree of incineration refers to the degree of treatment of the incineration waste by the first combustion unit in each combustion process. Here, the degree of incineration includes burnt-out and unburnt.

[0099] The first ratio can be set according to the actual situation. When the burnout ratio is less than the first ratio, it means that the first combustion unit has failed to reach the burnout standard many times during the combustion process of the incinerated waste, that is, the combustion is incomplete. This situation is usually caused by equipment failure of the first combustion unit (such as burner failure, poor ventilation system, etc.); in order to ensure that the first combustion unit can operate normally, efficiently and safely, and to ensure the effective treatment of waste, when this incomplete combustion occurs, the current first combustion unit needs to be shut down and repaired. Through shutdown and maintenance, the equipment can be comprehensively inspected, possible fault points can be found and repaired, so as to improve the combustion effect of the first combustion unit and make it meet or exceed the expected combustion effect standard again.

[0100] Furthermore, the method further comprises the following steps: When the burnout ratio is less than the second ratio and greater than or equal to the first ratio, obtaining the actual height of the waste to be incinerated corresponding to the incineration degree of the first combustion unit being unburned; the second ratio is greater than the first ratio; The maximum value of the preset height range is updated according to the actual height of the waste to be incinerated corresponding to the incineration degree of the first combustion unit being unburned.

[0101] It should be noted that the first ratio and the second ratio are set according to actual conditions. The first ratio is used as the lower threshold, and the second ratio is used as the upper threshold. When the burnout ratio is less than the second ratio and greater than or equal to the first ratio, it indicates that there are some unburned times in the first combustion unit. This may be caused by the maximum value of the preset height range being set too high. The minimum value of the actual height of the waste to be incinerated corresponding to the number of unburned times can be updated to the maximum value of the preset height range, so that the updated preset height range is compatible with the current state of the incinerator. The height of the waste to be incinerated that subsequently enters the first combustion unit is more in line with the requirements for complete combustion, thereby improving combustion efficiency and reducing the occurrence of unburned situations.

[0102] Furthermore, the method further comprises the following steps: The flue gas purification unit of the incinerator's incineration treatment system is used to remove harmful substances in the flue gas during and after the incineration process to ensure that the flue gas after incineration meets environmental protection standards.
