Description

BACKGROUND OF THE REVELATION Technical Area

[0001] This disclosure relates to a dust collection system, in particular a dust collection system with an addressing or display function for a deteriorated filter bag, and a display or addressing method for a deteriorated filter bag. Description of the state of the art

[0002] A dust collection system with bags filters the dust in the air by passing the polluted air through several filter bags to output cleaned air.

[0003] If the filter bag is damaged or deteriorated (for example, if the holes are enlarged), its filtration capacity can decrease, causing the dust content of the purified air to exceed the acceptable range. This condition can lead to air pollution, and the factory may be fined for violating environmental regulations.

[0004] To avoid this situation, the factory must regularly assign people to check all filter bags in order to identify and replace any broken or deteriorated filter bags.

[0005] However, this inspection process requires considerable labor and time, and the plant must be shut down during the inspection period. Furthermore, as the number of filter bags increases, the labor and time required for inspection also increase accordingly. Such dust collection systems are disclosed, for example, in DE 199 44 057 A1 and US 2011 / 0023709 A1. These patents describe dust collection systems in which at least a subset of the filter bags must be inspected manually.

[0006] CN214634791U further describes a control system for multiple dust collection containers.

[0007] Of course, directly replacing all filter bags could shorten the inspection time, but the cost of the filter bags would increase enormously.

[0008] Therefore, the aforementioned problems occur with bagged dust collection systems according to the state of the art, and effective solutions must be provided.

[0009] Therefore, the inventors examined the state of the art and searched intensively for solutions to the aforementioned problems. SUMMARY OF THE REVELATION

[0010] The purpose of the disclosure is to provide a dust collection system with a display or addressing function for a deteriorated filter bag and a display method for a deteriorated filter bag, which directly display or address the deteriorated filter bag by means of an air wash.

[0011] In some configurations, a dust collection system with addressing capability for a deteriorated filter bag is provided. The dust collection system comprises a blower, a cleaned-end dust concentration meter, and a control unit electrically connected to the blower and the cleaned-end dust concentration meter. The blower includes multiple blow tubes. The blower is configured to blow gas through the blow tubes to multiple filter bags to remove contaminants adhering to the filter bags. The cleaned-end dust concentration meter is positioned on the cleaned side of the filter bags to determine the contaminant level of the cleaned air.The control unit is configured to control the blowpipes in several pattern combinations to expel gas according to a specific pattern, and after each blow, it receives the pollutant level of the purified air for each pattern combination. The control unit is configured to identify one of the blowpipes in a corresponding pattern combination directed at a deteriorated filter bag when the pollutant level of the purified air indicates a deterioration, and it transmits a deteriorated filter bag warning for that blowpipe.

[0012] Some versions provide a notification procedure for a deteriorated filter bag in a dust collection system.The procedure comprises: a) successively controlling, based on a blowing pattern, several blow tubes of a blowing device in several pattern combinations to blow gas towards several filter bags in order to remove the pollutants adhering to the filter bags; b) obtaining a pollutant reading of the purified air for each pattern combination after gas has been blown through the dust concentration meter with a cleaned end, located on a cleaned side of the filter bags; and c) determining one of the blow tubes pointing towards the deteriorated filter bag in a corresponding pattern combination when one of the purified air pollutant readings indicates a deteriorated condition, and transmitting a deteriorated filter bag warning to the blow tube pointing towards the deteriorated filter bag.

[0013] The device can automatically address the deteriorated filter bag without interrupting dust collection.

[0014] The technical content of this disclosure will become clear from the detailed description of the statements and the accompanying drawings. The statements and drawings disclosed here serve only illustrative purposes and are not to be understood as limiting.

[0015] The disclosure provides a dust collection system with an addressing function for a deteriorated filter bag and a display method for a deteriorated filter bag, which can detect whether a deteriorated filter bag is present by means of a dust concentration meter with a cleaned end, which is arranged on the side of the cleaned air, and which performs the addressing and the required blow-gas isolation procedure by an air washing in various pattern combinations at the deteriorated filter bag in order to prevent the filter bag from deteriorating further.

[0016] Furthermore, the disclosure provides the blown gas in various pattern combinations to check the pollutant level of the purified air, which is measured with the dust concentration meter with a purified end, in order to correctly address the deteriorated filter bag and transmit a warning of the deteriorated filter bag.

[0017] If the addressing of the deteriorated filter bag is completed, but the deteriorated filter bag cannot be replaced in time, the disclosure can configure the blowpipe corresponding to the deteriorated filter bag so that it is in the isolated (non-blow gas) state to avoid contamination on the cleaned side.

[0018] In some configurations, the air scrubbing can be a reverse air scrubbing (hereinafter referred to as reverse air scrubbing). Reverse air scrubbing involves positioning the blower tube on the cleaned side (e.g., inside the filter bag) of each filter bag and blowing clean, high-pressure gas towards the filter bag. This allows the blown high-pressure gas to pass through the filter bag and remove contaminants (e.g., dust) adhering to the dirty side of the filter bag (e.g., the outside), thus restoring the filter bag's filtration capacity.

[0019] In some configurations, the air scrubbing can be a forward air scrubbing (hereinafter referred to as forward air scrubbing). Forward air scrubbing involves positioning the blowpipe on the soiled side of each filter bag (for example, on the outside of the filter bag) and blowing clean, high-pressure gas towards the filter bag to directly remove the contaminants adhering to the soiled side, thus restoring the filter bag's filtration capacity.

[0020] It should be noted that air washing with a broken or deteriorated air bag can cause many pollutants to reach the cleaned side and greatly increase the pollutant level on the cleaned side.

[0021] The disclosure can determine whether the filter bag is broken or deteriorated at each position by performing reverse air washing and checking the pollutant level on the cleaned side of each position in order to restore the filter bag's filter capacity.

[0022] With reference to Fig. 1: Fig. Figure 1 is the architectural diagram of the dust collection system according to some embodiments. The dust collection system 1 of the disclosure comprises a blowing device 11, a dust concentration measuring device 12 with a cleaned end, and a control unit 10, which is electrically connected to said devices.

[0023] The blowing device 11 comprises several blowing tubes 110. The blowing device 11 can transfer the compressed air to the blowing tube 110 so that the blowing tube 110 blows the gas to the filter bag 20 in order to remove the pollutants adhering to the corresponding filter bag 20.

[0024] The multiple blowpipes 110 can each be arranged on the cleaned sides of the multiple filter bags 20 and point towards the filter of each corresponding filter bag 20 to perform the reverse washing. This design is not to be considered restrictive.

[0025] The dust concentration meter 12 with cleaned end is arranged on the cleaned side of the filter bag 20 and configured to determine the cleaned pollutant level of the contaminated air after passing through the filter bag 20.

[0026] In some versions, the 12-inch dust concentration meter with a purified end can be a light absorption dust monitor, a light scattering dust monitor, a beta-beam dust monitor, an electrostatic induction dust monitor, a triboelectric dust monitor, or another type of dust monitor. The 12-inch dust concentration meter with a purified end can capture the ambient air to obtain the detected current signal (the unit of measurement can be mA) and convert the detected current signal into a purified pollutant value (for example, the unit for dust concentration can be mg / m³). 3 be).

[0027] The control unit 10 can be a computer, for example a PC, an industrial computer, or a control board, etc. Furthermore, the control unit 10 can contain a programmable controller, for example a ZE, a microprocessor, a SoC, an FPGA, etc.

[0028] The control unit 10 is configured to preset the blowing pattern 140 and control the multiple blowing tubes 110 in several pattern combinations to blow gas based on the received gas pattern 140. After the blowing of the gas according to each pattern combination is completed, the control unit 10 is configured to obtain the pollutant value of the purified air for each pattern combination after the gas has been blown through the purification sensor.

[0029] If the pollutant level of the purified air corresponds to a predetermined deterioration state, the control unit 10 can be configured to point the blowpipe (or blowpipes) 110 towards the deteriorated filter bag (or bags) in one or more blowpipes 110 detected by the corresponding pattern combination, and to transmit a warning from the deteriorated filter bag to the blowpipe 110 (for example, by transmitting a text message via the internet, transmitting a voice notification through the detector, transmitting a light notification through the indicator light, or transmitting a picture notification via the screen) to notify the administrator that the filter bag corresponding to the blowpipe 110 is broken or deteriorated.

[0030] Therefore, the dust collection system 1 of the disclosure can detect and address the deteriorated filter bag during the performance of the air washing of the filter bag 20.

[0031] In one embodiment of the invention, the blow pattern 140 is configured to group the multiple blow tubes 110 into different pattern combinations (grouping). Each pattern combination comprises multiple blow tubes 110 that do not overlap or partially overlap. The blow pattern 140 can define the blowing sequence of the multiple pattern combinations, for example, defining the blowing sequence, blowing time, blowing interval, etc., of the multiple pattern combinations.

[0032] For example, the control unit 10 can define pattern combination 1 based on the following sequence: controlling the selected pattern combination based on the blowing time to blow gas, waiting for the blowing interval after the gas blowing is complete, and obtaining the pollutant value of the purified air for pattern combination 1. The control unit 10 can define pattern combination 2 based on the following sequence: controlling the selected pattern combination based on the blowing time to blow gas, waiting for the blowing interval after the gas blowing is complete, and obtaining the pollutant value of the purified air for pattern combination 2, and so on.

[0033] In embodiments of the invention, a sample combination comprises several blowpipes 110.

[0034] With reference to Fig. 5 to Fig. 7: Fig. Figure 5 is a schematic representation of the blow pattern according to some specifications. Fig. Figure 6 is a schematic representation of the modified blow pattern according to some versions, and Fig. Figure 7 is a schematic representation of the modified blow pattern according to some descriptions.

[0035] In some versions, the dust collection system 1 includes ten blower tubes 110, which are indicated as connection 1 to connection 10.

[0036] As in Fig. As shown in Figure 5(I), the control unit 10 can simultaneously control all ports 1 to 10 to blow gas at the same time.

[0037] As in Fig. As shown in Figure 5(II), ports 1 to 10 are divided into two pattern combinations. Port 1, port 3, port 5, port 7, and port 9 constitute the first pattern combination. Port 2, port 4, port 6, port 8, and port 10 constitute the second pattern combination. The control unit 10 can control the first and second pattern combinations to alternately blow gas (blowing pattern 140).

[0038] As in Fig. As shown in Figure 5(III), ports 1 to 10 are divided into three pattern combinations. Port 1, port 7, port 7, and port 10 constitute the first pattern combination. Port 2, port 5, and port 8 constitute the second pattern combination. Port 3, port 6, and port 9 constitute the third pattern combination. The control unit 10 can control the first, second, and third pattern combinations to alternately blow gas (Blow Pattern 140).

[0039] Furthermore, if it is found that the pollutant level of the purified air exceeds the standard value after blowing the gas according to the second sample combination, the filter bags 20, which correspond to at least one of the connections 2, 5 and 8, may be determined to be deteriorated.

[0040] Furthermore, the filter bag 20 corresponding to port 8 can be identified as deteriorated by the display or addressing method of a deteriorated filter bag described below.

[0041] As in Fig. As shown in Figure 6, after the filter bag 20 corresponding to port 8 has been identified as deteriorated, the dust collection system 1 can change the blowing pattern 140 so that port 8 does not blow gas (isolated status) each time the second pattern combination is used to blow gas, until the deteriorated filter bag 20 is replaced by a new filter bag 20.

[0042] As in Fig. As shown in Figure 7, after the filter bag 20 corresponding to port 8 has been identified as deteriorated, the dust collection system 1 can change the blowing pattern 140 so that port 7 blows gas instead of port 8 each time the second pattern combination is used to blow gas, until the deteriorated filter bag 8 is replaced by a new filter bag 20.

[0043] Therefore, disclosure can prevent air washing from being carried out on the deteriorated filter bag in order to prevent the pollutant level of the purified air from exceeding the standard value.

[0044] With reference to Fig. 2: Fig. Figure 2 is the architectural diagram of the dust collection system according to some descriptions.

[0045] In some embodiments, the blowing device 11 may include a gas supply device 112 and several valves 111.

[0046] The gas supply device 112 is configured as a high-pressure gas source to supply high-pressure gas to the gas line and then to the valves 111. The gas supply device 112 may include a high-pressure air compressor or a compressed air tank, etc., and the specific device used is not considered limiting.

[0047] The multiple valves 111 (for example, an electromagnetic valve) are each arranged on the gas supply lines from the gas supply device 112 to the blast tubes 110. The multiple valves 111 are configured to control the volume of high-pressure gas flowing to each blast tube 110.

[0048] For example, if valve 111 is closed, the high-pressure gas is prevented from flowing to the corresponding blowpipe 110. If the valve is 50% open, 50% of the maximum volume of high-pressure gas flows to blowpipe 110. If valve 111 is fully open (100%), 100% of the maximum volume of high-pressure gas flows to blowpipe 110.

[0049] In some versions, the control unit 10 may include a sequence control interface 100. The sequence control interface 100 may be a control circuit board that is electrically connected to the gas supply device 112 and the valves 111. The sequence control interface 100 can control the open / closed state of the valves 110 based on the blow pattern 140.

[0050] In some versions, the sequence control interface 100 may be, for example, the programmable sequence control AEX from FineTek Co., Ltd., but the disclosure is not limited to this.

[0051] In some versions, if the number of valves 111 is too high to be connected through a single control interface 100, the control unit 10 may also include one or more expansion interfaces 101.

[0052] Each expansion interface 101 is electrically connected to the sequence control interface 100 and configured as an expansion interface of the sequence control interface 100.

[0053] Specifically, each expansion interface 101 can be configured to be electrically connected to one part of the valves 111. Furthermore, the sequence control interface 100 can be electrically connected to another part of the valves 111.

[0054] Once the configuration is complete, the sequence control interface 100 can directly control the valves 111 connected to it, causing them to open / close, and the expansion interface 101 can control the valves 111 connected to it, causing them to open / close. Thus, this disclosure solves the problem of an insufficient connection interface for the sequence control interface 100.

[0055] In some versions, the process control interface 100 and each expansion interface 101 may include a screen or an indicator light. The screen or indicator light may be configured to display the status of the valves 111 connected to it.

[0056] In some embodiments, the dust collection system 1 may include a storage device 14 that is electrically connected to the control unit 10. The storage device 14 may be configured to store data (for example, the blow pattern 140 and / or the deteriorated condition 141) and may contain a storage medium such as ROM, EEPROM, RAM, flash memory, etc.

[0057] In some versions, the storage device 14 may be a built-in memory or an external memory of the control unit 10, and these memories are not to be considered limiting.

[0058] The storage device 14 may include a non-volatile, computer-readable recording medium. The non-volatile, computer-readable recording medium is configured to store a computer program 142. The computer program 142 records the codes executable by the computer. When the control device 10 is configured to execute the codes, the control function and the addressing method for the deteriorated filter bags may be impaired in any embodiment of the disclosure.

[0059] In some configurations, the dust collection system 1 may include a dirty-end dust concentration meter 13, which is electrically connected to the control unit 10. The dirty-end dust concentration meter 13 may be of the same or similar type as the clean-end dust concentration meter 12. The dirty-end dust concentration meter 13 is located on the dirty side of the filter bag 20 and configured to measure the uncleaned pollutant concentration of the contaminated air before it passes through the filter bag 20.

[0060] Therefore, the disclosure can obtain the current filter capacity of the dust collection system 1 by comparing the uncleaned pollutant value with the cleaned pollutant value.

[0061] With reference to Fig. 3: Fig. Figure 3 is the schematic working diagram of the dust collection system according to some versions.

[0062] In some versions, the dust collection system 1 also includes an inlet 30, an air chamber 31, an outlet 32, several diaphragm valves 34 and a dust collection container 35.

[0063] In some embodiments, the dust concentration meter 13 with its contaminated end can be arranged at the inlet 30 to indicate the condition of the contaminated air before passing through the filter bag, and the dust concentration meter 12 with its cleaned end can be arranged at the outlet 32 ​​to indicate the condition of the cleaned air after passing through the filter bag. The valve 111 is the electromagnetic valve 33.

[0064] The dust-contaminated air is introduced through the inlet 30 at the lower part (contaminated side) of the air chamber 31 and passes through the several filter bags 20 to the upper part (cleaned side) of the air chamber 31. The dust is filtered out and retained on the contaminated side of the filter bag 20, thus transforming the contaminated air into clean air. The clean air is then expelled through the outlet 32.

[0065] During air washing (for example, reverse washing) on ​​the filter bags 20, the gas supply device 112 is configured to transfer the high-pressure gas through the line to the electromagnetic valve 33. The electromagnetic valve 33 opens to transfer the high-pressure gas through the line to the multiple diaphragm valves 34.

[0066] The high-pressure gas can forcibly open the several diaphragm valves 34 to remove the dust located on the filter bags 20 and thus perform air washing.

[0067] The diaphragm valve 34 is a diaphragm valve specifically configured for the dust collection system and is divided into an upper and a lower gas chamber by a diaphragm. The two gas chambers are connected to each other via the through-hole. The size of the through-hole is smaller than the size of the relief hole of the electromagnetic valve 33. When the relief hole of the electromagnetic valve 33 opens, the gas release velocity in the upper gas chamber is much greater than the velocity of the high-pressure gas entering from the line. The pressure in the upper gas chamber drops abruptly, causing the high-pressure gas, with its higher pressure in the lower gas chamber, to forcefully open the diaphragm. The high-pressure gas flows from the diaphragm valve 34 to the filter bag 20 and removes the dust adhering to the filter bag 20. The removed dust then falls into the dust collection container 35 for collection.

[0068] When the relief port of the electromagnetic valve 33 is closed, the pressure of the two gas chambers becomes approximately equal, and the housing spring can push the diaphragm downwards to cover the valve.

[0069] With reference to Fig. 4: Fig. Figure 4 shows the exterior of the dust collection system according to some specifications.

[0070] In some versions, the dust collection system 1 comprises an inlet 40, an air chamber 41, an outlet 42, a dust collection container 45, and a discharge opening 46. The inlet 40, the soiled side, the multiple filter bags 47, the cleaned side, and the outlet 42 define an airflow channel.

[0071] Inlet 40 is configured to introduce the contaminated gas. Air chamber 41 is configured to accommodate the filter bags 47. The arrangement of the filter bags divides air chamber 41 into a purified side, which communicates with outlet 42, and a contaminated side, which communicates with inlet 41. Outlet 42 is configured to expel the purified gas.

[0072] The dust collection container 45 is configured to collect pollutants (e.g., dust). The discharge opening 46 is located on the dust collection container 45 and configured to expel the pollutants collected in the dust collection container 45.

[0073] The gas supply line can include a main gas supply pipe 50, several gas supply branch pipes 52 and several blowpipes 53.

[0074] The main gas supply pipe 50 is connected to several gas supply branch pipes 52. Each gas supply branch pipe 52 is connected to one or more vent pipes 53 (all gas supply branch pipes 52 in Fig. 4 are connected to several blowpipes 53). Each blowpipe 53 is arranged in the corresponding filter bag 47.

[0075] In some designs, several valves 51 are arranged between each gas supply branch pipe 52 and the main gas supply pipe 50, for example in the connection area.

[0076] When each valve 51 is open, the main gas supply pipe 50 is connected to the corresponding gas supply branch pipes 52, and the high-pressure gas can be transferred from the main gas supply pipe 50 through the corresponding gas supply branch pipe 52 to the multiple blowpipes 53.

[0077] When each valve 51 is closed, the main gas supply pipe 50 and the corresponding gas supply branch pipe 52 are separated from each other, and the high-pressure gas is blocked in the main gas supply pipe 50.

[0078] With reference to Fig. 16: Fig. Figure 16 is the flowchart of the deteriorated filter bag addressing method according to some implementations. The deteriorated filter bag addressing method of the implementation comprises steps S10 to S14 for performing deterioration detection and may further include step S15 to automatically change the blow pattern 140 after the deterioration of the filter bag has been detected.

[0079] Step S10: The control unit 10 is configured to control - based on the blowing pattern 140 - the multiple blowing tubes 110 of the blowing device 11 in several pattern combinations to blow gas into the multiple filter bags 20 in order to remove the pollutants adhering to the filter bags 20.

[0080] Step S11: The control unit 10 is configured to obtain a pollutant value of the purified air for each pattern combination after the gas has been blown through a dust concentration meter 12 with a purified end.

[0081] Step S12: Control unit 10 is configured to determine whether the pollutant level of the purified air corresponds to the deterioration state. For example, whether the pollutant level of the purified air is higher than the predetermined deterioration threshold.

[0082] If the pollutant level of the purified air corresponds to the deterioration state, the control unit 10 is configured to execute step S13.

[0083] Step S13: The control unit 10 is configured to detect, in a pattern combination where the pollutant value of the purified air indicates a deteriorated condition, one of the blow tubes 110 pointing to the deteriorated filter bag of one or more blow tubes 110 and to transmit a warning of the deteriorated filter bag for the blow tube 110.

[0084] If the pollutant level of the purified air does not correspond to the deterioration state, or if step S13 is completed, the control unit 10 is configured to execute step S14.

[0085] Step S14: The control unit 10 is configured to determine whether deterioration detection should be stopped. For example, when the air washing of all filter bags 20 is complete, the user stops deterioration detection, etc.

[0086] If deterioration detection does not need to be stopped, control unit 10 is configured to repeat step S10 to continuously perform air washing and deterioration detection.

[0087] When the deterioration detection is stopped and one of the filter bags 20 is detected as deteriorated, the control unit 10 is configured to execute step S15.

[0088] Step S15: The control unit 10 is configured to change the blow pattern 140 to change the blow tube 110, which points towards the deteriorated filter bag, so that it does not blow out gas (isolated status).

[0089] In some versions, the control unit 10 can be configured to further change the blowing pattern 140 to replace the blowing tube 110 pointing towards the deteriorated filter bag with another blowing tube 110 blowing gas, so that the blowing tube 110 pointing towards the deteriorated filter bag is stopped to prevent the filter bag from deteriorating further.

[0090] The disclosure can effectively detect whether a deteriorated filter bag is present without interrupting dust collection and can address the deteriorated filter bag.

[0091] With reference to FIG, 8. Fig. 14 and Fig. 15: Fig. Figure 8 is a schematic representation of the blow pattern according to some specifications. Fig. 14 is the schematic representation of the blow pattern according to some versions, and Fig. Figure 15 is the schematic representation of the blow pattern according to some descriptions.

[0092] In the illustrations of FIG, 8. Fig. 14 and Fig. The dust collection system comprises 16 blower tubes, which are indicated as A1-A4, B1-B4, C1-C4 and D1-D4.

[0093] The Fig. The 8 blowing patterns shown divide the 16 blowpipes into four pattern combinations, namely the blowpipes A1-A4 (first pattern combination), the blowpipes B1-B4 (second pattern combination), the blowpipes C1-C4 (third pattern combination) and the blowpipes D1-D4 (fourth pattern combination).

[0094] As in Fig. As shown in Figure 8(i) in the first period, the control unit 10 is configured to control the blow tubes A1-A4 (first pattern combination) so that they blow gas and detect the first pollutant value of the purified air according to the first pattern combination.

[0095] As in Fig. As shown in Figure 8(ii) in the second period, the control unit 10 is configured to control the blow tubes B1-B4 (second pattern combination) to blow gas and to detect the second pollutant value of the purified air according to the second pattern combination.

[0096] As in Fig. As shown in Figure 8(iii) in the third period, the control unit 10 is configured to control the blow tubes C1-C4 (third pattern combination) to blow gas and to detect the third pollutant value of the purified air according to the third pattern combination.

[0097] Furthermore, in the third period, the control unit 10 detects that the third pollutant value of the purified air corresponds to the deteriorated condition according to the third sample combination, and can determine that at least one of the blow tubes C1-C4 points towards the deteriorated filter bag 20.

[0098] As in Fig. As shown in Figure 8(iv) in the fourth period, the control unit 10 is configured to control the blow tubes D1-D4 (fourth pattern combination) to blow gas and to detect the fourth pollutant value of the purified air according to the fourth pattern combination.

[0099] The Fig. The 14 blowing patterns shown divide the 16 blowpipes into two pattern combinations, namely the blowpipes A1-A2, B2-B3, C3-C4, D1 and D4 (first pattern combination) and the blowpipes A3-A4, B1, B4, C1-C2 and D2-D3 (second pattern combination).

[0100] As in Fig. As shown in Figure 14(i) in the first period, the control unit 10 is configured to control the blow tubes of the first pattern combination so that they blow gas and to detect the first pollutant value of the purified air according to the first pattern combination.

[0101] As in Fig. As shown in the second period in Figure 14(ii), the control unit 10 is configured to control the blow tubes of the second pattern combination so that they blow gas and to detect the second pollutant value of the purified air according to the second pattern combination.

[0102] The Fig. The 15 blowing patterns shown divide the 16 blowpipes into two groups, namely the blowpipes A1-A4, B1-B4, C1-C4, D1-D4 (first group) and the blowpipes B2-B3, C2-C3 (second group).

[0103] Furthermore, the first and second groups have different rotational frequencies. The first group is divided into rotational frequencies of four periods per unit of time to obtain a low filter frequency, and the second group is divided into rotational frequencies of two periods per unit of time to obtain a high filter frequency.

[0104] Furthermore, the first group has four pattern combinations, such as blowpipes A1-A4 (first pattern combination), blowpipes B1-B4 (second pattern combination), blowpipes C1-C4 (third pattern combination), and blowpipes D1-D4 (fourth pattern combination). The second group has two pattern combinations, such as blowpipes B2, C3 (fifth pattern combination) and blowpipes B3, C2 (sixth pattern combination).

[0105] As in Fig. As shown in Figure 15(i) in the first period, the control unit 10 is configured to control the blow tubes of the first pattern combination and the fifth pattern combination so that they blow gas, and to detect the collective first pollutant value of the purified air according to the first pattern combination and the fifth pattern combination.

[0106] As in Fig. As shown in the second period in Figure 15(ii), the control unit 10 is configured to control the blow tubes of the second pattern combination and the sixth pattern combination so that they blow gas, and to detect the second pollutant value of the purified air according to the second pattern combination and the sixth pattern combination.

[0107] As in Fig. As shown in the third period in Figure 15(iii), the control unit 10 is configured to control the blow tubes of the third pattern combination and the fifth pattern combination so that they blow gas, and to detect the collective third pollutant value of the purified air according to the third pattern combination and the fifth pattern combination.

[0108] As in Fig. As shown in the fourth period in Figure 15(iv), the control unit 10 is configured to control the blow tubes of the fourth pattern combination and the sixth pattern combination so that they blow gas, and to detect the fourth pollutant value of the purified air according to the fourth pattern combination and the sixth pattern combination.

[0109] With reference to Fig. 16 and Fig. 17: Fig. Figure 17 is the parts flow diagram of the deteriorated filter bag addressing method according to some embodiments. In comparison with the deteriorated filter bag addressing method according to the embodiment in Fig. 16 includes step S13 in the addressing method of the deteriorated filter bag in Fig. 17 the steps S20-S24 for executing the addressing of the deteriorated filter bag.

[0110] Step S20: If the pollutant level of the purified air of one of the pattern combinations corresponds to the deteriorated condition, the control unit 10 is configured to reduce the blowpipe quantity in the combination or to change the blowpipes in the combination and to carry out the gas blowing process according to the new pattern combination.

[0111] According to the invention, the control unit 10 performs the addressing based on the trigger time. Specifically, the control unit 10 is configured to obtain the trigger time (for example, the time required from the blowing of the gas until the purified pollutant value is obtained) of each blow tube 110, to obtain the response time from the blowing of the gas according to the current pattern combination until the purified pollutant value is received, to compare the response time with the trigger time of each blow tube 110, and to identify the consistent blow tube 110 as the blow tube of the deteriorated filter bag.

[0112] Step S21: The control unit 10 is configured to obtain the pollutant value of the purified air of the new sample combination through the dust concentration meter 12 with purified end.

[0113] Step S22: The control unit 10 is configured to determine whether the pollutant level of the purified air corresponds to the deterioration state.

[0114] If the pollutant level of the purified air does not correspond to the deterioration state, the control unit 10 is configured to execute step S14.

[0115] If the pollutant level of the purified air corresponds to the deterioration state, the control unit 10 is configured to execute step S23.

[0116] Step 23: The control unit 10 is configured to determine whether the addressing of the deteriorated filter bag is complete. For example, if the blowpipe 110 pointing towards the deteriorated filter bag 20 is confirmed, or if the deteriorated filter bag corresponding to the blowpipe 110 cannot be confirmed, all possible attempts are made to reduce or change the blowpipes in the combination.

[0117] If the addressing of the deteriorated filter bag is not completed, the control unit 10 is configured to repeat step S20 so that the addressing is performed continuously.

[0118] Once the addressing of the deteriorated filter bag is complete, control unit 10 is configured to perform step S24.

[0119] Step S24: The control unit 10 is configured to transmit the deteriorated filter bag warning to the blowpipe 110, which points to the deteriorated filter bag.

[0120] In some configurations, for example when reducing the blast tube volume in the combination, the control unit 10 can be configured to divide the standard combination into several sub-combinations, so that the gas is blown according to these sub-combinations. The blast tube volume according to the standard combination is larger than the blast tube volume of each sub-combination.

[0121] The control unit 10 is configured to perform the following steps to execute the addressing: blowing the gas according to the several sub-combinations of the pattern combination; obtaining the pollutant value of the purified air of each sub-configuration after blowing the gas; if any of the pollutant values ​​of the purified air indicates a deteriorated condition, reducing the blow volume in the sub-combination to blow the gas again and check until the blow tube 110, which points towards the deteriorated filter bag, is determined.

[0122] With reference to Fig. 8 and Fig. 9: Fig. Figure 9 is a schematic representation of the blow pattern according to some specifications.

[0123] In Fig. 8 at least one of the blowpipes C1-C4 (third pattern combination) is determined to be the blowpipe that points in the direction of the deteriorated filter bag 20.

[0124] Thus, control unit 10 can be configured to split the third pattern combination for blowing the gas into two sub-combinations. The two sub-combinations are C1-C2 (first sub-combination) and C3-C4 (second sub-combination).

[0125] As in Fig. As shown in Figure 9(i) in the fifth period, the control unit 10 is configured to control the first sub-combination for blowing the gas and to detect the pollutant value of the purified air according to the first sub-combination.

[0126] As in Fig. As shown in Figure 9(ii) in the sixth period, the control unit 10 is configured to control the second sub-combination for blowing the gas and to detect the pollutant level of the purified air according to the second sub-combination.

[0127] Furthermore, in the sixth period, the control unit 10 detects that the pollutant level of the purified air corresponds to the deteriorated condition according to the second subcombination, and can determine that at least one of the blow tubes C3-C4 points towards the deteriorated filter bag 20.

[0128] Thus, control unit 10 can be configured to split the second sub-combination for blowing the gas into two further sub-combinations. These two sub-combinations are C3 (third sub-combination) and C4 (fourth sub-combination).

[0129] As in Fig. As shown in Figure 9(iii) in the seventh period, the control unit 10 is configured to control the third sub-combination for blowing the gas and to detect the pollutant level of the purified air according to the third sub-combination.

[0130] As in Fig. As shown in Figure 9(iv) in the eighth period, the control unit 10 is configured to control the fourth sub-combination for blowing the gas and to detect the pollutant value of the purified air according to the fourth sub-combination.

[0131] Furthermore, in the eighth period, the control unit 10 detects that the pollutant level of the purified air corresponds to the deteriorated condition according to the fourth subcombination, and can determine that the blower tube C4 points towards the deteriorated filter bag 20.

[0132] Thus, the disclosure can precisely address the deteriorated filter bag.

[0133] The control unit 10 is configured to obtain the trigger time of each blow tube 110 in the pattern configuration and to determine the blow tube 110 of the deteriorated filter bag by the response time of the current pollutant value of the purified air and the trigger time of each blow tube 110.

[0134] Specifically, the control unit 10 is configured to perform the following steps to execute the addressing: Determining the wind speed of the duct and several trigger distances (these can be pre-stored in the memory device 14), where each trigger distance is the distance from each filter bag 20 to the dust concentration meter 12 with the cleaned end; Calculating the multiple trigger times of the blow tubes 110 based on the wind speed of the duct and the multiple trigger distances; Obtaining a response time from the moment the gas of the pattern combination is blown until the corresponding pollutant value of the cleaned air is received; Selecting the blow tube 110 with the trigger time that corresponds to the response time for the blow tube 110 pointing towards the deteriorated filter bag.

[0135] With reference to Fig. 8, Fig. 10 and Fig. 11: Fig. 10 is the relationship diagram of the blower control and the pollutant value according to some explanations, and Fig. Figure 11 is the schematic representation of the trigger time table according to some explanations.

[0136] As in Fig. As shown in Figure 10, the control unit 10 is configured in the time interval 0-t1 (blowing time) to control the first pattern combination (the blow tubes A1-A4) so ​​that the blow tubes continuously blow gas. In the time interval t1-t2 (blowing gap), the control unit 10 is configured to stop all pattern combinations so that they do not blow gas, and to obtain the pollutant level of the purified air (pollutant level) of the first pattern combination by the dust concentration meter 12 with a purified end.

[0137] During the time interval t2-t3 (blowing time), the control unit 10 is configured to control the second pattern combination (the blow tubes B1-B4) so ​​that the blow tubes continuously blow gas. During the time interval t3-t4 (blowing gap), the control unit 10 is configured to stop all pattern combinations so that they do not blow gas, and to obtain the pollutant level of the purified air from the second pattern combination using the dust concentration meter 12 with a purified end.

[0138] During the time interval t4-t5 (blowing time), the control unit 10 is configured to control the third pattern combination (the blow tubes C1-C4) so ​​that the blow tubes continuously blow gas. During the time interval t5-t6 (blowing gap), the control unit 10 is configured to stop all pattern combinations so that they do not blow gas, and to obtain the pollutant level of the purified air of the third pattern combination by the dust concentration meter 12 with a purified end.

[0139] Furthermore, at a time near t6 (for example, t5 + 6.9 seconds), the control unit 10 is configured to detect the pollutant level of the purified air corresponding to the deteriorated state using the dust concentration meter 12 with the purified end. In other words, one of the blower tubes C1-C4 is pointing towards the deteriorated filter bag.

[0140] During the time interval t6-t7 (blowing time), the control unit 10 is configured to control the fourth pattern combination (the blow tubes D1-D4) so ​​that the blow tubes continuously blow gas. During the time interval t7-t8 (blowing gap), the control unit 10 is configured to stop all pattern combinations so that they do not blow gas, and to obtain the pollutant level of the purified air of the fourth pattern combination by the dust concentration meter 12 with a purified end.

[0141] As in Fig. As shown in Figure 11, the control unit 10 can be configured to calculate the trigger time of each blowpipe and obtain the response time (6.9 seconds). Furthermore, the control unit 10 can be configured to compare the response time and the trigger time of each blowpipe in order to identify the blowpipe with the shortest time, i.e., blowpipe C4 (7 seconds).

[0142] Therefore, the control unit 10 can determine that the blowpipe C4 is pointing towards the deteriorated filter bag.

[0143] It should be noted that the blowing gap must be larger than the trigger time of all blowpipes in order to correctly determine the blowpipe pointing towards the deteriorated filter bag based on the time difference.

[0144] In some configurations, for example when changing the blast tubes, the control unit 10 can be configured to set the other pattern combinations (hereinafter referred to as modified combinations) so that they differ from the current pattern combination (the original pattern combination), and then to blow the gas using the modified combinations. The blast tubes 110 of each modified combination partially overlap with the blast tubes 110 of the original pattern combination.

[0145] The control unit 10 can be configured to perform the following steps to execute the addressing: blowing gas after several modified combinations that partially overlap with the original combination; obtaining the pollutant value of the purified air of each modified combination after gas blowing; determining the modified combination with the pollutant value of the purified air that corresponds to the deteriorated condition after gas blowing; configuring the blow tube 110, which overlaps in the modified combination and the original pattern combination, as the blow tube 110 that points towards the deteriorated filter bag.

[0146] With reference to Fig. 8 and Fig. 12: Fig. Figure 12 is the schematic representation of the blow pattern according to some versions.

[0147] The Fig. The 12 blow patterns shown divide the 16 blowpipes into four modified combinations, such as blowpipes A1, B1, C1, D1 (first modified combination), blowpipes A2, B2, C2, D2 (second modified combination), blowpipes A3, B3, C3, D3 (third modified configuration) and blowpipes A4, B4, C4, D4 (fourth modified combination).

[0148] As in Fig. As shown in Figure 12(i) in the fifth period, the control unit 10 is configured to control the blow tubes of the first modified combination so that they blow gas, and to detect the pollutant level of the purified air according to the first modified combination.

[0149] As in Fig. As shown in Figure 12(ii) in the sixth period, the control unit 10 is configured to control the blow tubes of the second modified combination so that they blow gas, and to detect the pollutant level of the purified air according to the second modified combination.

[0150] As in Fig. As shown in Figure 12(iii) in the seventh period, the control unit 10 is configured to control the blow tubes of the third modified combination so that they blow gas, and to detect the pollutant level of the purified air according to the third modified combination.

[0151] As in Fig. As shown in Figure 12(iv) in the eighth period, the control unit 10 is configured to control the blow tubes of the fourth modified combination so that they blow gas, and to detect the pollutant level of the purified air according to the fourth modified combination.

[0152] Furthermore, in the eighth period, the control unit 10 detects that the pollutant level of the purified air corresponds to the deteriorated condition according to the fourth subcombination, and can determine that at least one of the blower tubes A4, B4, C4, D4 points towards the deteriorated filter bag 20.

[0153] Furthermore, in Fig. 8 at least one of the blowpipes C1-C4 is determined to be the blowpipe that points in the direction of the deteriorated filter bag 20.

[0154] Therefore, when the detection results are combined, the filter bag corresponding to blowpipe C4 (the overlapping part of the third pattern combination and the fourth modified combination) can be identified as deteriorated.

[0155] With reference to Fig. 8 and Fig. 13: Fig. Figure 13 is the schematic representation of the modified blow pattern according to some specifications.

[0156] Once the addressing of the deteriorated filter bag 20 is complete, the control unit 10 can be configured to change the blowing pattern. For example, the blowing tube C4, which corresponds to the deteriorated filter bag, can be stopped and replaced by the adjacent blowing tubes B4 and D4.

[0157] The modified blowing pattern is carried out specifically as follows.

[0158] As in Fig. As shown in Figure 13(i) in the first period, the control unit 10 is configured to control the blow tubes A1-A4 (first pattern combination) so that they blow gas.

[0159] As in Fig. As shown in Figure 13(ii) in the second period, the control unit 10 is configured to control the blow tubes B1-B4 (second pattern combination) so that they blow gas.

[0160] As in Fig. As shown in Figure 13(iii) in the first period, the control unit 10 is configured to control the blow tubes C1-C3, B4, D4 (modified third pattern combination) so that they blow gas.

[0161] Therefore, the decrease in dust collection function resulting from the non-use of blower tube C3 can be compensated for by the increased function of blower tubes B4, D4.

[0162] As in Fig. As shown in Figure 13(iv) in the fourth period, the control unit 10 is configured to control the blow tubes D1-D4 (fourth pattern combination) so that they blow gas.

[0163] Fig. Figure 18 is the parts flow diagram of the deteriorated filter bag addressing method according to some embodiments. In some embodiments, the deteriorated state includes a condition in which the accumulating amount reaches a deterioration threshold. The accumulating amount is the accumulation of the magnitudes of the pollutant levels in the purified air after blowing the gas according to the same pattern combination, which is greater than the deterioration threshold.

[0164] In comparison with the addressing method of the deteriorated filter bag according to the design in Fig. 16 includes step S12 in the addressing method of the deteriorated filter bag in Fig.18 the steps S30-S32 for carrying out the determination of the deteriorated condition.

[0165] Step S30: Control unit 10 is configured to determine whether the pollutant level of the purified air corresponds to the predetermined deterioration threshold. The deterioration threshold could be, for example, the upper limit of the maximum pollutant concentration set by the government or the factory.

[0166] If the pollutant level of the purified air does not correspond to the deterioration threshold, the control unit 10 is configured to execute step S14.

[0167] If the pollutant level of the purified air corresponds to the deterioration threshold, the control unit 10 is configured to execute step S31.

[0168] Step S31: The control unit 10 is configured to perform multiple acquisition processes according to the current pattern combinations in order to obtain the pollutant values ​​of the purified air from the multiple repeated acquisition processes.

[0169] The number of repeated measurements can be configured arbitrarily, depending on the requirements. For example, it can be greater than the deterioration threshold.

[0170] Step S32: The control unit 10 is configured to determine whether the accumulating amount of pollutant levels in the purified air is greater than the deterioration threshold obtained from the re-samples.

[0171] If the cumulative amount of pollutant levels in the purified air is greater than the deterioration threshold achieved by repeating the measurement (for example, if the cumulative amount of pollutant levels in the purified air is greater than the predetermined deterioration threshold, about 5 times), filter bag 20 is detected as deteriorated, after which step S13 is performed.

[0172] If the cumulative amount of pollutant levels in the purified air is greater than the deterioration threshold achieved by repeating the measurement, or if the predetermined deterioration threshold is not reached, filter bag 20 is recorded as not deteriorated, after which step S14 is performed.

[0173] Therefore, disclosure can reduce erroneous judgments and increase the accuracy of data collection.
