It is a waste gas purification device that efficiently treats industrial waste gas. In the process of filtering industrial waste gas, impurities contained in the newly incoming waste gas will gradually block the filter screen of the filter device, causing the amount of waste gas passing through the filter device to gradually decrease, resulting in a pressure difference between the fans blowing air before and after the filter device, affecting the timely cleaning of impurities blocking the surface of the filter screen and the normal filtration of industrial waste gas. In order to avoid this problem, it is necessary to monitor the blockage of the filter screen of the filter device in a timely manner, adjust the power of the fans before and after the filter screen according to the blockage, and clean the filter screen in a timely manner.

[0024] According to the maximum power loss and the relative blockage degree of the target filter box at the suspected abnormal moment, the adjusted blockage degree of the target filter box at the suspected abnormal moment is obtained.

[0025] Further, the method of obtaining the adjusted blockage degree of the target filter box at the suspected abnormal moment according to the maximum power loss and relative blockage degree of the target filter box at the suspected abnormal moment includes the following specific methods:

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0038] Figure 2 A flowchart for adjusting the blockage degree provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 , which shows a flow chart of a method for monitoring the operating energy consumption of a regenerative incinerator provided by an embodiment of the present invention, the method comprising the following steps:

[0041] Step S001, collecting the pressure difference data of each filter box at each collection time, the fan energy consumption of the fans before and after the filter box, and the power loss of the fan after the filter box at different collection times during the operation of the regenerative thermal incinerator.

[0042] In order to ensure the stable operation of the thermal incinerator, the filtering device of the thermal incinerator includes multiple filter boxes, and the purpose of different filter boxes is to filter particles of different diameters. A differential pressure gauge is installed on both sides of the filter box. Inside the filter box, the filter screen entering the filter box and the filter screen exiting the filter box contain two preset fans, and energy consumption sensors are respectively set on these two fans. It can be understood that since the two fans contained in the filter box are respectively located at the filter screen position entering the filter box and the filter screen position exiting the filter box, the two fans are respectively recorded as the fan before the filter box and the fan after the filter box.

[0043] During the operation of the regenerative heat incinerator, a collection time is set every 1 minute. At each collection time, a differential pressure gauge is used to obtain the pressure difference data of the industrial waste gas on both sides of the filter box, an energy consumption sensor is used to obtain the fan energy consumption of the fans before and after the filter box, and an energy consumption sensor is used to obtain the power loss of the fan after the filter box.

[0044] Preferably, in one embodiment of the present application, 1 minute is used as the time interval between adjacent collection moments. In actual application, as other implementation methods, the implementer can decide the value of the time interval between adjacent collection moments according to actual conditions, and the present application does not impose any special restrictions.

[0045] At this point, the pressure difference data of the filter box and the fan energy consumption of the fans before and after the filter box, as well as the power loss of the fan after the filter box are obtained.

[0046] Step S002, according to the values ​​and value differences of the pressure difference data at adjacent collection moments, obtain the pressure difference ratio difference at the collection moments, and according to the pressure difference ratio difference at all collection moments during the operation of the regenerative thermal incinerator, filter the suspected abnormal moments in the collection moments.

[0047] When impurities gradually clog the filter box, the power and energy consumption of the fans on both sides of the filter box can be adjusted according to the degree of blockage, and then the wind speed of the fans on both sides of the filter box can be adjusted to reduce the degree of adsorption of the blockage on the filter screen of the filter box, help the blockage fall into the filter box, and clean the filter screen in time to ensure the normal filtration of industrial waste gas by the thermal storage incinerator.

[0048] In order to accurately evaluate the blockage of the filter, it is considered that the more serious the impurities block the filter box, the greater the pressure difference on both sides of the filter box, that is, the greater the pressure difference data of the filter box, so the filter is evaluated based on the pressure difference data of the filter box.

[0049] For any collection time during the operation of the regenerative thermal incinerator, when the pressure difference data at the collection time is not 0, the collection time is recorded as the target collection time. According to the difference between the pressure difference data at the target collection time and the adjacent collection time, the pressure difference ratio difference at the target collection time is obtained.

[0050] Preferably, as an embodiment of the present application, the ratio of the pressure difference data between the previous adjacent collection time of the target collection time and the target collection time is recorded as the pressure difference ratio at the target collection time, and the absolute value of the difference between the pressure difference ratio at the target collection time and the first preset threshold is recorded as the pressure difference ratio difference at the target collection time.

[0051] Among them, in this embodiment, the value of the first preset threshold is 1. The implementer can decide the value of the first preset threshold according to the actual situation, and this application does not impose any special restrictions.

[0052] The greater the difference between the pressure difference data at the target collection time and the previous adjacent collection time, the greater the possibility of a blockage problem at the target collection time and the more serious the blockage problem. At this time, the pressure difference ratio difference at the target collection time is greater.

[0053] A first comparison threshold is set. When the pressure difference ratio is greater than the first comparison threshold, the target acquisition moment is determined to be a suspected abnormal moment. The suspected abnormal moment is the moment when a blockage problem may occur. Among them, the value of the first comparison threshold in this embodiment is 0.2. The implementer can decide the value of the first comparison threshold according to the actual situation, and this application does not impose any special restrictions.

[0054] It is understandable that for the collection moments when the pressure difference data is 0 during the operation of the regenerative thermal incinerator, the pressure on both sides of the filter box is the same, and there is no problem of impurity blockage. Therefore, there is no need to calculate the pressure difference ratio difference for these collection moments, nor is there any need to analyze whether there is a blockage problem based on the pressure difference ratio difference, that is, these collection moments are not suspected abnormal moments. At the same time, it is understandable that the first collection moment during the operation of the regenerative thermal incinerator is not analyzed.

[0055] At this point, the moment of suspected abnormality is determined.

[0056] Step S003, according to the difference between the fan energy consumption of the fans before and after the filter box at the suspected abnormal moment and the adjacent collection moment, and the difference between the pressure difference data, the blockage degree at the suspected abnormal moment is obtained, and according to the blockage degree of the adjacent filter box at the same suspected abnormal moment, and the power loss of the fans after each filter box in the adjacent filter box at the same suspected abnormal moment, the adjusted blockage degree of the filter box at the suspected abnormal moment is obtained.

[0057] When the filter box is clogged with impurities, the industrial waste gas transported by the fan in front of the filter box cannot reach the filter box smoothly due to the blocked impurities, resulting in greater pressure on the fan position and increased fan energy consumption. Therefore, based on the difference between the fan energy consumption at the suspected abnormal moment and the adjacent collection moment, the energy consumption ratio difference at the suspected abnormal moment is obtained.

[0058] Preferably, as an embodiment of the present application, the average fan energy consumption of the fans before and after the filter box at the target collection moment is recorded as the average fan energy consumption at the target collection moment, the ratio of the average fan energy consumption at the previous adjacent collection moment of the suspected abnormal moment to the suspected abnormal moment is recorded as the energy consumption ratio at the suspected abnormal moment, and the normalized value of the absolute value of the difference between the energy consumption ratio at the suspected abnormal moment and the first preset threshold is recorded as the energy consumption ratio difference at the suspected abnormal moment.

[0059] It should be noted that this embodiment uses the Z-Score standard normalization method to calculate the normalized value. In actual application, the implementer may use other methods in the prior art such as the maximum and minimum value normalization method to calculate the normalized value, which is not limited here.

[0060] It is understandable that during the operation of the thermal incinerator, the fans before and after the filter box continue to run, so the fan energy consumption at the suspected abnormal moment is not equal to 0, and there is no situation where the denominator is zero in the calculation process of the energy consumption ratio difference at the suspected abnormal moment.

[0061] The greater the difference between the fan energy consumption at the previous adjacent collection time before the suspected abnormal moment and the suspected abnormal moment, the greater the possibility of a blockage problem at the suspected abnormal moment and the more serious the blockage problem. At this time, the greater the difference in energy consumption ratio at the suspected abnormal moment.

[0062] Furthermore, the degree of blockage at the suspected abnormal moment is obtained based on the difference in pressure difference data between the suspected abnormal moment and the adjacent collection moments, and the difference in energy consumption ratio at the suspected abnormal moment.

[0063] Preferably, as an embodiment of the present application, the absolute value of the difference between the pressure difference data at the previous adjacent collection time of the suspected abnormality and the suspected abnormality time is recorded as the absolute value of the pressure difference at the suspected abnormality time, and the product of the absolute value of the pressure difference at the suspected abnormality time and the energy consumption ratio difference at the suspected abnormality time is recorded as the degree of blockage at the suspected abnormality time.

[0064] In actual application, as another implementation method, the sum of the absolute value of the pressure difference at the suspected abnormality moment and the difference in energy consumption ratio at the suspected abnormality moment is recorded as the blockage degree at the suspected abnormality moment.

[0065] The greater the difference in pressure difference data between the suspected abnormal moment and the adjacent collection moment, and the greater the difference in energy consumption ratio at the suspected abnormal moment, the greater the possibility that the filter box has a blockage problem at the suspected abnormal moment, and the more serious the blockage problem. At this time, the degree of blockage at the suspected abnormal moment is greater.

[0066] The filtering device of the regenerative heat incinerator includes multiple filter boxes for filtering particles of different diameters. When the filter box is blocked, the flow rate, speed and other characteristics of the industrial waste gas passing through the filter box will change. Since the industrial waste gas passes through different filter boxes in sequence, the adjacent filter boxes on both sides of the filter box will also be affected by the blocked filter box. Therefore, the adjusted blockage degree of the filter box at the suspected abnormal moment is obtained according to the blockage degree of the adjacent filter boxes at the same suspected abnormal moment and the power loss of the fan behind each filter box in the adjacent filter boxes at the same suspected abnormal moment.

[0067] Preferably, in one embodiment of the present application, any filter box is recorded as a target filter box, the adjacent filter boxes on both sides of the target filter box are recorded as adjacent filter boxes of the target filter box, and the maximum value of the power loss of the target filter box and the adjacent filter boxes at the suspected abnormal moment is recorded as the maximum power loss of the target filter box at the suspected abnormal moment; the maximum value of the blockage degree of the target filter box and the adjacent filter box at the suspected abnormal moment is recorded as the maximum blockage degree of the target filter box at the suspected abnormal moment, the minimum value of the blockage degree of the target filter box and the adjacent filter box at the suspected abnormal moment is recorded as the minimum blockage degree of the target filter box at the suspected abnormal moment, the ratio of the maximum blockage degree to the minimum blockage degree of the target filter box at the suspected abnormal moment is recorded as the relative blockage degree of the target filter box at the suspected abnormal moment, and the linear normalized value of the product of the maximum power loss of the target filter box at the suspected abnormal moment and the relative blockage degree is recorded as the adjusted blockage degree of the target filter box at the suspected abnormal moment.

[0068] It should be noted that this embodiment uses the Z-Score standard normalization method to calculate the normalized value. In actual application, the implementer may use other methods of the prior art such as the maximum and minimum value normalization method to calculate the normalized value, which is not limited here. At the same time, it should be noted that when the target filter box is the first filter box, the target filter box does not have a previous filter box, and the filter boxes adjacent to the target filter box on both sides only include the next filter box of the target filter box; when the target filter box is the last filter box, the target filter box does not have a next filter box, and the filter boxes adjacent to the target filter box on both sides only include the previous filter box of the target filter box; when the target filter box is any filter box excluding the first filter box and the last filter box, the filter boxes adjacent to the target filter box on both sides include the previous filter box of the target filter box and the next filter box of the target filter box.

[0069] When the power loss of the target filter box and the adjacent filter box at the suspected abnormal moment is greater, and the difference between the maximum and minimum values ​​of the blockage degree of the target filter box and the adjacent filter box at the suspected abnormal moment is greater, at the suspected abnormal moment, the target filter box and the adjacent filter box are more likely to be affected by the filter box blockage problem, and the degree of being affected by the filter box blockage problem is more serious. At this time, the target filter box has a greater adjusted blockage degree at the suspected abnormal moment.

[0070] The same method can be used to obtain the adjustment blockage degree of any filter box at any suspected abnormal moment.

[0071] At this point, the adjustment blockage degree of all filter boxes at all suspected abnormal moments is obtained. The flow chart for adjusting the blockage degree is as follows: Figure 2 shown.

[0072] Step S004, obtaining the abnormal monitoring result of the operating energy consumption of the thermal incinerator according to the adjustment blockage degree of the filter box at the suspected abnormal moment.

[0073] When the adjustment blockage degree of the filter box at the suspected abnormal moment is greater, at the suspected abnormal moment, the target filter box and the adjacent filter box are more likely to be affected by the filter box blockage problem, and the more seriously they are affected by the filter box blockage problem, the more they need to adjust the energy consumption and wind speed of the fans before and after the filter box. It is understandable that when the filter box is more likely to be affected by the filter box blockage problem, and the more seriously they are affected by the filter box blockage problem, the energy consumption and wind speed of the fans before and after the filter box should be reduced to reduce the degree of adsorption of the blockage on the filter screen of the filter box, and help the blockage fall into the filter box.

[0074] According to the adjustment blockage degree of the filter box at the suspected abnormal moment, the target fan energy consumption of the filter box at the next collection moment of the suspected abnormal moment is determined.

[0075] Preferably, in one embodiment of the present application, the difference between the first preset threshold and the adjusted blockage degree of the filter box at the moment of suspected abnormality is recorded as the first difference of the filter box at the moment of suspected abnormality, and the product of the fan energy consumption of the filter box at the moment of suspected abnormality and the first difference is recorded as the target fan energy consumption of the filter box at the next collection moment of the suspected abnormality.

[0076] The target fan energy consumption of the filter box at the next collection moment of the suspected abnormal moment is used as the value of the fan energy consumption of the filter box at the next collection moment of the suspected abnormal moment. At the same time, the operating energy consumption monitoring result of the thermal storage incinerator at the collection moment is determined to be abnormal, thereby realizing the monitoring and control of the operating energy consumption of the thermal storage incinerator at the suspected abnormal moment.

[0077] It is understandable that when a certain collection time is not at a suspected abnormal time, the operating energy consumption monitoring result of the thermal incinerator at the collection time is determined to be normal.

[0078] At this point, the monitoring results of the operating energy consumption of the thermal incinerator are obtained.

[0079] Based on the same inventive concept as the above method, an embodiment of the present invention also provides an operation energy consumption monitoring system for a thermal storage incinerator, comprising a memory, a processor, and a computer program stored in the memory and running on the processor, wherein the processor implements the steps of any one of the above-mentioned methods for monitoring the operation energy consumption of a thermal storage incinerator when executing the computer program.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
