Description

Technical Field

[0001] The present invention relates to the technical field of material mechanics, and in particular to a wear detection method and system for a grate plate of a garbage incinerator. Background Art

[0002] Waste incineration is a technology that is widely promoted and used in China. Waste incinerators are important equipment and facilities in waste incineration power plants, among which grate plates are key components. Grate plates are heat-resistant cast steel, generally nickel-chromium alloy, with good heat resistance. Grate plates are the main components in direct contact with garbage in the furnace of the waste incinerator. On the one hand, they are cooled by the bottom combustion air (180℃-250℃) in the furnace, and on the other hand, the weight of the garbage is also borne on the top of the grate plates. During the movement, the speed of garbage burning is different. In the combustion area of ​​the incinerator, as the furnace temperature increases, the garbage layer above the grate plates is thinned, and some areas may be burned through. The temperature on the top of the grate plates may reach more than 400℃. In this case, the grate plates are very likely to cause wear and failure, which will increase the amount of slag leakage from the grate. Since the high-temperature burned ash slag generally has a higher hardness, the wear of the grate plates will be further aggravated during the movement. With the increase of garbage classification and calorific value, the wear of grate plates is becoming more and more serious, and the service life is shortened to less than 1 year. Therefore, it is urgent to improve the high-temperature wear resistance of grate plates.

[0003] The actual reason for the failure of the grate slices is the result of high-temperature corrosion and mechanical wear. At present, there is no standard detection method and device for detecting the life of waste incineration grate slices in China. There are two main ways to detect the life of the grate slices. One is to make the surface hardness of the grate slices reach HB230 or above through heat treatment, and the service life of the grate slices is estimated by hardness. However, since the measured hardness is the hardness at room temperature, and the actual working hardness is high-temperature hardness, it may change greatly, so the estimated life is difficult to be accurate and cannot be used for quantitative detection. One is to put it into the waste incinerator for verification, and test the life of the grate slices through the actual operating conditions of waste incineration. Due to the different working conditions in the furnace of the waste incinerator and the different areas where the grate slices are placed, the temperature and load conditions in the furnace are also different. The life of the grate slices estimated in this way is not statistically representative, and it takes a long time, and it is difficult to adapt to the iterative updates of new materials and new processes for grate slice manufacturing technology or anti-corrosion and anti-wear technology. Summary of the invention

[0057] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0058] Figure 1 A schematic diagram of a grate plate wear detection method provided by an embodiment of the present invention is shown below. Figure 1 The embodiments of the present invention are described in detail.

[0059] A method for detecting wear of a grate plate comprises: step S100, step S200, step S300 and step S400.

[0060] Step S100: obtaining relevant parameters of the friction medium, and establishing a grate plate wear calculation model according to the relevant parameters; the relevant parameters include the friction coefficient and material hardness of the friction medium.

[0061] Specifically, the calculation model of the wear amount includes:

[0062]

[0063] Wherein, Q is the wear amount of the grate plate, Ks is the friction coefficient of the friction medium, W is the load on the grate plate, L is the friction distance, and H is the material hardness of the friction medium.

[0064] Step S200: obtaining the friction distance between the grate plate and the friction medium within a preset time.

[0065] Specifically, the sliding friction track between the grate plate and the friction medium is circular, and the calculation formula of the friction distance is as follows:

[0066] L = π × d × m;

[0067] Wherein, d is the rotation diameter of the grate piece, and m is the number of rotations of the grate piece per unit time.

[0068] Step S300: Calculate the wear amount of the grate plate within a preset time according to the wear amount calculation model and the friction distance.

[0069] During the test, the wear amount of the grate plate can be obtained by measuring the actual thickness of the grate plate after a preset period of time.

[0070] The preset time may be one week, one month or one year, so as to facilitate the measurement of the wear amount.

[0071] It is understandable that the wear amount of the grate plate is related to the load W to which the grate plate is subjected, and is also related to the temperature to which the grate plate is subjected, wherein the temperature affects the hardness H of the material.

[0072] Specifically, the calculation formula for the wear amount a' of the grate plate within a preset time includes:

[0073]

[0074] Wherein, F0 is the initial load, F1 is the load after the change, b1 is the wear amount of the grate plate under the load after the change, and ε is the proportional coefficient.

[0075] Furthermore, the calculation formula for the wear amount b1 of the grate plate under the changed load includes:

[0076]

[0077] Among them, T 0 is the initial temperature, T 1 is the temperature after the change, c1 is the temperature of the grate after the change T 1 The wear amount under the condition of B is the temperature coefficient.

[0078] Step S400: obtaining a maximum wear limit value, and calculating and outputting the wear life of the grate plate according to the maximum wear limit value and the calculation result of the wear amount within a preset time.

[0079] Specifically, the calculation formula of the wear life of the grate plate includes:

[0080]

[0081] Wherein, n is the number of rotations of the grate slice per unit time. 0 is the number of frictions of the grate piece per unit time in the actual production process, a' is the wear amount of the grate piece within the preset time, E is the maximum wear limit of the grate piece, and h1 is the service life of the grate piece in the actual production process.

[0082] That is, by setting the number of rotations of the grate per minute n and n 0 By measuring the actual thickness a' of the grate plate wear within a preset period of time and the upper limit E of the grate plate wear, the service life h1 of the grate plate can be calculated.

[0083] The above-mentioned method for detecting the wear of a grate plate obtains relevant parameters of a friction medium, and establishes a wear calculation model for the grate plate based on the relevant parameters; obtains the friction distance between the grate plate and the friction medium within a preset time; calculates the wear of the grate plate within a preset time based on the wear calculation model and the friction distance; obtains a maximum wear limit, and calculates and outputs the wear life of the grate plate based on the maximum wear limit and the calculation result of the wear within the preset time; realizes the construction of a wear detection model for the grate plate, solves the problem in the prior art that the life measurement of the grate plate cannot be quantitatively and efficiently detected, and proposes a method for quantitatively detecting the life of the grate plate under changing conditions of different parameters such as coupled friction medium, load, and temperature.

[0084] The wear detection method for a grate plate provided by the present invention is further described below with reference to a specific example.

[0085] As shown in the figure, Figure 2-Figure 4 This is a schematic diagram of the structure of a grate plate wear detection device provided by the first embodiment of the present invention. Figure 3 for Figure 2 The cross-sectional view at AA, Figure 2 for Figure 3 The cross-sectional view at BB, Figure 4 The embodiment of the present invention provides a grate wear detection device, comprising a machine body 1, the machine body 1 having a box body 1.1, an upper through hole 1.1A is arranged at the center of the top surface of the box body 1.1, the lower part of the box body is a funnel structure and a lower through hole is arranged at the bottom, and the friction medium enters the box body 1.1 from the upper through hole 1.1A and flows out from the lower through hole 1.1B.

[0086] A left rotating mechanism 2A and a right rotating mechanism 2B are respectively arranged on the left and right sides of the box body 1.1. The left rotating mechanism 2A comprises a left motor 2A1 and a left fixed base 2A2.1 fixed on the front side wall, the left motor 2A1 is mounted on the left fixed base 2A2.1, a front bearing seat 2A2.1A and a rear bearing seat 2A2.1B are respectively mounted on the front and rear side walls of the box body, a left rotating shaft 2A3 is also arranged, the rotating shaft 2A3 is mounted in the front bearing seat 2A2.1A and the rear bearing seat 2A2.1B, a left rotating seat 2A4 is also arranged on the left rotating mechanism 2A, the left rotating seat 2A4 is mounted on the left rotating shaft 2A3, and the left motor 2A1 drives the left rotating shaft 2A3 to rotate. A fixing assembly 5 for mounting the grate plate is arranged on the left rotating seat 2A4, and the fixing assembly includes a fixing screw 5.1 and a fixing nut 5.2. Corresponding mounting holes are arranged on the grate plate. After the fixing screw 5.1 passes through the mounting hole of the grate plate, the grate plate is pressed and fixed by the fixing nut 5.2.

[0087] A left grate sheet 3A and a right grate sheet 3B are respectively installed on the left rotating seat and the right rotating seat. When the left rotating mechanism 2A and the right rotating mechanism 2B are running at the same time, the two grate sheets rotate at the same time and are in the same straight line and there is a gap 4 between them when they are in the closest state; the gap 4 is aligned with the upper through hole 1.1A in the vertical direction, and the friction medium enters the box body 1.1 from the upper through hole 1.1A, falls into the gap 4, and is squeezed and rubbed with the continuously rotating left grate sheet 3A and right grate sheet 3B, then falls into the funnel at the bottom of the box body, and finally flows out from the lower through hole 1.1B. By setting a screw conveyor, the friction medium flowing out of the lower through hole 1.1B is continuously conveyed to the upper through hole 1.1A of the box body 1.1 to achieve a circulating flow of the friction medium; a thermal resistor 7 is also arranged inside the box body to heat the friction medium inside the box body.

[0088] Figure 5 The second embodiment of the present invention is a schematic diagram of the structure. The figure shows that, unlike the first embodiment, in this embodiment, a left counterweight 5A and a right counterweight 5B are respectively provided on the left grate plate 3A and the right grate plate. The figure shows that after the fixing screw passes through the counterweight, the fixing nut presses and fixes the counterweight and the grate plate.

[0089] Specifically, the above device is used to calculate the life of the grate slices under the conditions of initial temperature and original load.

[0090] By rotating one of the grate plates, a certain gap will exist between the rotating grate plate and the fixed grate plate; different media are selected, and quartz sand, iron sand, etc. with different particle sizes are introduced into the furnace gap, so that the rotating grate plate and the fixed grate plate rub against each other, resulting in mechanical wear at the initial temperature. By measuring the wear depth over a certain period of time, the curve and functional relationship between the wear depth of a certain medium and time at the initial temperature can be inferred.

[0091] At the initial temperature (such as 25°C) and given a certain friction medium, the calculation model of wear volume Among them, Ks friction coefficient and material hardness H are constants. Without increasing the load, W is also a constant value. L is a function of time t. It can be concluded that the sliding distance per minute can be calculated by the following formula:

[0092] L = π × d × m;

[0093] Where d is the rotation diameter of the grate, and m is the number of rotations per minute. From the above, it can be seen that the wear amount is a function of the number of wear cycles (number of rotations). From the above formula, it can also be concluded that the wear amount is directly proportional to the number of rotations under the conditions of a given friction medium, a given load, a given hardness, and a given rotation diameter of the grate.

[0094] Therefore, assuming that the single friction amount of the grate plate is a, and the upper limit thickness of the grate plate wear is E, since the depth a of a single friction is difficult to measure, by accumulating a period of time (for example, 1 month), the friction depth a' can be measured to characterize the service life h1 of the grate plate under the initial temperature and initial load. The calculation formula is:

[0095]

[0096] The above formula assumes that the number of frictions during the test is the same as the actual working condition. To further shorten the test time, the number of rotational frictions of the grate can be accelerated. If the number of frictions per minute simulated n is greater than the number of frictions n0 under the actual grate burning condition, the life formula is:

[0097]

[0098] That is, by setting the number of rotations n of the grate plate per minute, by measuring the actual thickness a' of wear in one month, and the upper limit E of the wear of the grate plate, the service life h1 of the grate plate can be calculated.

[0099] Specifically, the above device is used to calculate the life of the grate slices under the conditions of initial temperature and changed load.

[0100] By changing the counterweight on the rotating grate (simulating the weight of the material on the grate), the load on the grate during actual working process can be simulated. By giving the rotation speed, number of rotations and friction medium of the fixed rotating grate, the initial temperature, the changed load and the wear curve of the grate with different counterweights under a certain friction medium can be obtained.

[0101] That is, under the condition of a specific friction medium, the wear amount of the grate plate under the initial load F0 is a', and the single friction depth of the changed load F1 is b1. According to the calculation model of the wear amount, it is determined under a given friction medium, namely Ks; given friction distance L (i.e., a fixed test for 1 month, the rotation diameter d of the grate plate remains unchanged), under the initial temperature state (material hardness H remains unchanged), the load W is directly proportional to the friction depth Q, and the proportional coefficient is set to ε.

[0102] The calculation formula is as follows:

[0103]

[0104] The correlation coefficient ε can be calculated by the wear amount Q under different loads at the same time. The maximum load under actual working conditions is F1, and the wear amount is b1. In order to further shorten the test time, the rotation friction of the grate plate can be accelerated, and the simulated friction times per minute n is greater than the friction times n0 under the actual grate plate burning conditions. According to the calculation formula of the wear life of the grate plate and the calculation formula of the wear amount a', the life formula of the grate plate can be derived as follows:

[0105]

[0106] By changing the load W, and given the number of grate plate rotations n, that is, the maximum load F1, the grate plate life h1 can be calculated by measuring the actual thickness b1 of the grate plate wear in one month and the upper limit E of the grate plate wear depth.

[0107] Specifically, the above device is used to calculate the life of the grate plate after the temperature changes, the load changes and the number of wear times changes.

[0108] Fixed medium and counterweight, by changing different resistance wires for heating, to change the working temperature of the rotating grate, the wear curves of fixed medium and fixed counterweight at different temperatures can be obtained. Through coupling analysis of the wear depth of the hardest medium, the largest counterweight, and the highest temperature, the minimum service life of the grate can be quantitatively inferred according to the thickness of the grate wear zone.

[0109] According to the calculation relationship between metal temperature and hardness:

[0110] H=A×e -B×T ;

[0111] Among them, A is the hardness at absolute zero (0K), B is the temperature coefficient, and e is the natural logarithm. For a specific material, A and B are both constants. The value of B can be obtained according to different temperatures and hardnesses.

[0112] Under the condition of given friction length (i.e. same time, same speed) and given load, according to the calculation model of wear amount, the wear amount Q is an inverse proportional function of hardness. Under the initial temperature state, the wear amount at temperature T0 is a', the wear amount at normal temperature T0 under the condition of maximum load F1 is b1, and the wear amount at the changed temperature T1 is c1. Then, according to the calculation model of wear amount, the following formula can be derived:

[0113] c1×H 1 =b1×H 0 ;

[0114] Among them, H0 is the hardness at room temperature T0, and H1 is the hardness of the material at temperature T1. According to the formula H = A × e -B×T , the following formula is obtained:

[0115]

[0116] At this time, according to different temperatures and different loads, the life formula of the grate is combined with the formula Different wear amounts c can be obtained, and the following formula is available:

[0117]

[0118] By changing the load F, given the number of grate plate rotations n, given the maximum load F1, given the maximum operating temperature T1, and measuring the actual thickness c1 of the grate plate wear after 1 month and the upper limit E of the grate plate wear depth, the grate plate life h1 can be calculated.

[0119] At this time, the expected service life h1 of the grate plate is coupled with the rotation number variable, load variable, and temperature variable. By measuring the actual wear amount c1 in one month, the expected service life of the grate plate can be inferred.
