[0002] During the combustion production process of sodium silicate glass natural gas kiln, strict control of the natural gas kiln is required to ensure product quality.

[0003] During the combustion process, natural gas kilns must consider internal temperature fluctuations. In the practical application of existing combustion control devices or systems, the combustion process is often affected by changes in charging, discharging, and environmental factors, ultimately causing the melting process to deviate from the target process. Frequent manual corrections to the target gas flow rate are required to restore the melting process to the normal range. Although sodium silicate glass natural gas kilns are guided by theory and experience in combustion production, there is a lack of effective control methods for the internal temperature field.

[0004] Therefore, the present invention proposes a sodium silicate glass natural gas kiln combustion control system to achieve faster temperature self-adjustment and more accurate temperature control. Summary of the Invention

[0065] The combustion cycle is the total combustion time of a specified batch of materials during combustion and melting, and the preheating time of the kiln is not included in the combustion cycle. The required temperature is the preset temperature parameter;

[0066] SA2. Then, within the combustion cycle, plot the kiln temperature of each analysis period in chronological order into a line graph;

[0067] SA3, then obtain the corresponding total values ​​of kiln temperature and natural gas flow at adjacent broken line nodes in the broken line graph;

[0073] SA7, then according to V c =Q c / (d*W c *c), calculate the compensation air flow of the adjacent broken line node;

[0074] Wherein, d represents the density of natural gas, and c represents the specific heat capacity of natural gas. In this embodiment, the specific heat capacity is approximately regarded as a fixed constant;

[0075] In this embodiment, natural gas is supplied by a municipal pipeline network, and its quality requirements meet the national natural gas Class II standard. Furthermore, the supplier regularly provides natural gas test reports. Based on the data on the test reports, including calorific value and main components, the user assumes that the composition of the natural gas will not change significantly over a week. Therefore, the user considers its main parameters to be constant, and its density, specific heat capacity, and calorific value are approximately fixed.

[0076] In the above calculation, if the kiln temperature of the previous node on a set of adjacent broken line nodes is greater than the kiln temperature of the next node, it means that the kiln is in a cooling state at this stage, and the resulting compensation air flow rate is negative;

[0077] If the kiln temperature of the previous node on a set of adjacent broken line nodes is lower than the kiln temperature of the next node, it means that the kiln is in a heating state at this stage, and the resulting compensation air flow is positive;

[0078] An analysis database is used to classify and store the compensation gas flow rate classified by the data classification unit, and the analysis database includes a first data area and a second data area, the first data area is used to store the compensation gas flow rate with a positive value, and the second data area is used to store the compensation gas flow rate with a negative value;

[0079] and the first data area and the second data area each contain a plurality of pre-constructed compensation pools, and the compensation pools contain a plurality of pre-constructed analysis sub-pools;

[0080] By acquiring historical combustion data corresponding to multiple previous combustion cycles of the kiln, and then calculating and analyzing the historical combustion data through the analysis and calculation unit, a large amount of compensation gas flow is obtained, realizing the collection of big data, and realizing effective compensation of natural gas flow based on data analysis, maximizing the use of previously recorded data information. At the same time, the retained previously recorded data information can facilitate operators to view the data of the corresponding combustion cycle, playing a role in effective traceability of product processing;

The temperature difference interval set includes multiple preset temperature difference intervals, and one temperature difference interval is marked on an analysis sub-pool.

[0083] The classification is as follows:

[0084] SX1. Taking a compensation air flow as an example, obtain the positive and negative values ​​of the compensation air flow;

[0085] SX2, then storing the compensation air flow into the corresponding data area according to the positive or negative value of the compensation air flow;

[0086] If the compensation gas flow value is positive, it is stored in the first data area;

[0087] If the compensation air flow value is negative, it is stored in the second data area;

[0088] SX3. Then, in the adjacent broken line node corresponding to the compensation gas flow, obtain the kiln temperature of the previous broken line node;

[0089] Then match the kiln temperature of the broken line node with each temperature interval in the temperature interval set:

[0090] If the kiln temperature exists in a temperature interval in the temperature interval set, it means that the kiln temperature matches the temperature interval, and then the compensation gas flow is introduced into the compensation pool marked corresponding to the temperature interval;

[0092] If the absolute value of the temperature difference exists in a temperature difference interval in the temperature difference interval set, it means that the absolute value of the temperature difference matches the temperature difference interval, and then the compensation gas flow is introduced into the analysis sub-pool marked corresponding to the temperature difference interval;

[0093] SX5, and so on, storing each compensation gas flow into the corresponding analysis sub-pool;

[0094] By classifying and storing the compensation air flow through the data classification unit, the compensation air flow corresponding to different furnace temperatures can be accurately controlled. The compensation air flow corresponding to different temperature differences can effectively improve the efficiency of the kiln temperature control unit in obtaining the corresponding compensation air flow, thereby facilitating the kiln temperature control unit to calculate and analyze the corresponding compensation air flow, thereby achieving the effect of precise temperature control;

[0095] The kiln temperature control unit is used to perform real-time temperature control on the required temperature of each combustion period in the current combustion cycle by combining the compensation gas flow in the analysis database;

[0096] The combustion period is pre-divided by the operator within the combustion cycle, and each combustion period is set with a corresponding required temperature. The required temperature is a preset temperature parameter, which represents the temperature that needs to be controlled in the kiln during the combustion period.

[0097] The temperature control method is as follows:

[0098] SS1. Obtain the kiln temperature during the current combustion period. In this embodiment, the preheating temperature of the kiln is not within the combustion cycle. Therefore, during the initial combustion period of the current combustion cycle, the kiln has a certain temperature.

[0099] At the same time, the required temperature of the next adjacent combustion period is obtained;

[0100] SS2: Subtract the required temperature of the next combustion period from the kiln temperature of the current combustion period to obtain the corresponding required temperature difference;

[0101] SS3. Then, according to the positive and negative values ​​of the required temperature difference, determine the data area corresponding to the compensation air flow to be selected;

[0102] If the required temperature difference is a positive value, the first data area is selected;

[0103] If the required temperature difference is a negative value, the second data area is selected;

[0104] SS4. Then, based on the kiln temperature of the current combustion period, a compensation pool corresponding to the temperature interval set including the current kiln temperature is selected from the corresponding data area;

[0105] SS5. Then, according to the required temperature difference, select the analysis sub-pool corresponding to the temperature difference interval set containing the required temperature difference in the corresponding compensation pool;

[0106] SS6. Then, all compensation air flows are obtained from the corresponding analysis sub-pools, and the degree of dispersion of all compensation air flows in the corresponding analysis sub-pools is calculated. Then, based on a preset discrete threshold, the compensation air flows that cause excessive dispersion are eliminated, and the remaining compensation air flows are retained and their mean is calculated, and the mean is recorded as the flow compensation value. The degree of dispersion is a commonly used technique in this field.

[0107] In this embodiment, the specific method of calculating the flow compensation value according to the discrete degree is:

[0108] First, use the formula: , get the discrete value L of all compensation airflow, then compare the calculated discrete value L with L0, if L>L0, it is considered that the discrete value L of this group is too large, according to |BC i -BC p |Eliminate the corresponding BC in order from large to small i The remaining discrete values ​​L are calculated accordingly, until L≤L0, and then all BCs that have not been eliminated are obtained. i value, and retain the compensation air flow that is not eliminated, and then calculate the mean value of the compensation air flow that is not eliminated;

[0109] Among them, BC i Indicates the corresponding compensation gas flow in the corresponding analysis sub-pool, i=1, 2, ... n, n indicates the number of compensation gas flows in the corresponding analysis sub-pool, i indicates the number, in this embodiment, if the value of i is 3, then BC i Indicates the third compensation gas flow in the corresponding analysis sub-pool; BC p It represents the average value of the mean of all data parameters in the information set, and L0 is the preset discrete threshold;

[0110] SS7. Then, the number of all kiln air inlet pipes is obtained, and the flow compensation value is divided by the number of kiln air inlet pipes to obtain the compensation allocation value. Then, the opening of each kiln air inlet pipe is adjusted according to the compensation allocation value, so that the sum of the natural gas flow values ​​at all air inlet pipe positions in the next combustion period is equal to the sum of the natural gas flow values ​​of each air inlet pipe in the current combustion period plus the compensation allocation value.

[0111] By analyzing historical kiln combustion data and obtaining a large amount of compensation air flow, the current combustion temperature and the preset required temperature are then analyzed, and the corresponding compensation air flow is obtained based on the analysis results. Then, the corresponding compensation distribution value is allocated to the natural gas flow value of each air inlet pipe based on the compensation air flow, and then the opening of the kiln air inlet pipe is adjusted in turn, so that the precise distribution of natural gas flow can be achieved. The present invention can achieve faster temperature self-adjustment and more accurate temperature control characteristics, reduces the labor intensity of employees, and improves the accuracy of kiln combustion temperature control, thereby optimizing the kiln's combustion effect on sodium silicate glass, improving product quality and yield, and has significant economic benefits and promotion value.

[0112] In the practical application of this embodiment, the melting temperature is controlled using a preset desired temperature as the reference temperature. In automatic control, the combustion air flow and natural gas flow are automatically proportioned for combustion control (K value = combustion air flow ÷ natural gas flow). The natural gas flow is calculated based on the natural gas flow during the previous combustion period combined with a compensation value. In manual control, the operator manually adjusts the natural gas valve opening and the combustion air fan frequency based on temperature changes and the combustion conditions within the kiln to achieve temperature control. The K value is a proportional setpoint, and its changes are primarily based on the combustion conditions within the kiln and the oxygen content of the flue gas. The combustion air flow is measured by a combustion air flow meter at the kiln air inlet.

[0113] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0114] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.

Then, the absolute value of the temperature difference corresponding to the compensation air flow is matched with each temperature difference interval in the temperature difference interval set: If the absolute value of the temperature difference exists in a temperature difference interval in the temperature difference interval set, it means that the absolute value of the temperature difference matches the temperature difference interval, and then the compensation gas flow is introduced into the analysis sub-pool marked corresponding to the temperature difference interval; SX5, and so on, store each compensation gas flow into the corresponding analysis sub-pool.

6. The sodium silicate glass natural gas kiln combustion control system according to claim 2, characterized in that: The temperature control method is as follows: SS1. Obtain the kiln temperature of the current combustion period and the required temperature of the next adjacent combustion period; SS2: Subtract the required temperature of the next combustion period from the kiln temperature of the current combustion period to obtain the corresponding required temperature difference; SS3. Then, according to the positive and negative values ​​of the required temperature difference, determine the data area corresponding to the compensation air flow to be selected; SS4. Then, based on the kiln temperature of the current combustion period, a compensation pool corresponding to the temperature interval set including the current kiln temperature is selected from the corresponding data area; SS5. Then, according to the required temperature difference, select the analysis sub-pool corresponding to the temperature difference interval set containing the required temperature difference in the corresponding compensation pool; SS6. Then, all compensation airflows are obtained from the corresponding analysis sub-pools, and the degree of dispersion of all compensation airflows in the corresponding analysis sub-pools is calculated. Then, based on the preset discrete threshold, the compensation airflows that cause excessive dispersion are eliminated. The remaining compensation airflows are retained and their mean is calculated, and the mean is recorded as the flow compensation value. SS7. Then, the number of all kiln air inlet pipes is obtained, and the flow compensation value is divided by the number of kiln air inlet pipes to obtain the compensation allocation value. Then, the opening of each kiln air inlet pipe is adjusted according to the compensation allocation value, so that the sum of the natural gas flow values ​​at all air inlet pipe positions in the next combustion period is equal to the sum of the natural gas flow values ​​of each air inlet pipe in the current combustion period plus the compensation allocation value.
