The cloth bag dust collector is a dry dust filter which is suitable for collecting fine, dry and non-fibrous dust. The dust removing cloth bag (or called a filter bag) is made of woven filter cloth or non-woven felt, dust-containing gas is filtered by utilizing the filtering action of fiber fabric, and when the dust-containing gas enters the cloth bag dust remover, dust with large particles and large specific gravity falls down due to the action of gravity and falls into an ash bucket, and when the gas containing finer dust passes through the cloth bag, the dust is adsorbed on the outer surface of the dust removing cloth bag, so that the discharged gas is purified.
In the working process of the bag-type dust collector, as the dust content is mostly doped with heavy metal, strong acid, water and the like, the dust collector and the bag can be corroded and damaged along with the increase of the service time, so that the bag is damaged and leaked.

Fig. 1 is a schematic structural diagram of a dust collector detection system according to an embodiment of the present invention, as shown in fig. 1, the dust collector detection system includes:
the dust concentration detector comprises a bag-type dust collector body 1, a dust concentration detector 2 with a camera 21 and a control device 3.
Wherein, sack cleaner body 1 includes: a lower box 11, a middle box 12, an upper box 13 and a pulse back-blowing structure 14.
Specifically, one side of the lower box body 11 is provided with an air inlet 111, and the middle box body 12 is provided with N dust collection cloth bags 121, wherein N is more than or equal to 1; an air outlet 131 is provided at one side of the upper case 13.
During the operation of the bag-type dust collector, dust-containing flue gas enters the lower box 11 from the air inlet 111, and then during the process of entering the upper box 13 through the middle box 12, dust and gas in the dust-collecting bag 121 in the middle box 12 are separated due to the filtering effect of the dust-collecting bag, the dust is adsorbed on the outer surface of the dust-collecting bag 121, and the gas enters the upper box 13 and is discharged from the air outlet 131.
In addition, as the working time increases, more dust is deposited on the outer surface of the dust collection cloth bag 121, so that the resistance of the dust collection cloth bag 121 gradually increases, and the amount of gas passing through the dust collection cloth bag 121 gradually decreases, so that the resistance is controlled within a limited range (generally 1300-1800 pa) in order for the dust collector to work normally. Therefore, the dust remover is also provided with a pulse back-blowing structure 14 for blowing dust accumulated on the surface of the dust removing cloth bag 121.
Specifically, the pulse back-blowing structure 14 includes N pulse valves 141, gas storage bags 142 and N blowing pipes 143, the lower ends of the N blowing pipes 143 extend into the upper box 13, the N pulse valves 141 and the N blowing pipes 143 are in one-to-one correspondence, and the N blowing pipes 143 and the N dust collection bags 121 are in one-to-one correspondence.
The control device 3 is respectively connected with the N pulse valves 141, in the operation process of the dust remover, the control device 3 sequentially opens the N pulse valves 141, compressed air in the air storage bag 142 is sprayed into the corresponding dust removing cloth bag 121 by the corresponding spraying pipe 143, the corresponding dust removing cloth bag 121 is rapidly expanded under the instant reverse action of air flow, dust accumulated on the surface falls off, and the dust removing cloth bag 121 is regenerated.
The cleaned dust falls into a dust hopper (not shown in the figure), and the dust accumulated on the dust removing cloth bag 121 is cleaned regularly, so that the cleaned gas passes through normally, and the normal operation of the dust remover is ensured.
In this embodiment, the detection of whether the N dust collection bags 121 are damaged is mainly implemented by collecting the air outlet images when the N dust collection bags 121 are respectively blown, and analyzing the collected air outlet images to determine the dust concentration measurement value corresponding to each dust collection bag 121.
Accordingly, the dust concentration detector 2 is provided in the upper case 13 to collect an image of the vicinity of the air outlet 131 of the upper case 13, that is, to collect an air outlet image.
Specifically, the control device 3 is respectively connected with the dust concentration detector 2 and the N pulse valves 141, and is configured to sequentially control the N pulse valves to open, respectively obtain air outlet images collected by the dust concentration detector 2 during the opening period of each pulse valve, analyze the air outlet images to respectively obtain actual dust concentration measurement values corresponding to dust collection bags corresponding to each pulse valve, and compare the actual dust concentration measurement values with reference dust concentration measurement values to respectively determine whether the N dust collection bags are damaged, where the reference dust concentration measurement values correspond to dust concentration measurement values when the N dust collection bags are not damaged.
Alternatively, the control device 3 may be provided locally or remotely with respect to the precipitator body 1, which control device 3 may be integrated with or separate from the dust concentration detector 2 when provided locally. When the control device 3 is separately provided from the dust concentration detector 2, communication can be performed therebetween by a wired or wireless communication means, and therefore, it can be understood that a communication interface is provided at this time on the control device 3 and the dust concentration detector 2.
In practical application, optionally, a detection device for detecting a resistance value corresponding to the dust removing cloth bags 121 may be disposed in the dust remover body, specifically, the detection device may be disposed on a surface of each or any one of the dust removing cloth bags 121, and when the detected average resistance reaches a certain threshold value, a trigger signal is sent to the control device 3 to trigger the control device 3 to sequentially control the N pulse valves 141 to open. Of course, alternatively, the control device 3 may perform the periodic opening control on the N pulse valves 141 according to a preset control period, for example, sequentially control the N pulse valves 141 to be opened every 24 hours. It can be understood that the opening sequence of the N pulse valves and the opening maintaining time of each pulse valve may be preset, and the opening maintaining time of each pulse valve is 2 seconds, so that only one pulse valve is opened at each time point, that is, only one dust collecting bag is blown at each time point, and therefore, which dust collecting bag is currently blown can be positioned by the opening sequence of the N pulse valves and the time of the current initial triggering of the blowing control.
Alternatively, the dust concentration detector 2 may be operated all the time, i.e. the video of the air outlet 131 is collected all the time, or may be controlled by the control apparatus 3 to operate only during the opening of the N pulse valves 141.
Taking the example that the control device 3 currently controls any pulse valve i to be opened, the dust concentration detector 2 sends the collected video to the control device 3, and the control device 3 positions a video segment corresponding to the pulse valve i from the received video according to the time for starting the pulse valve i and the preset opening maintaining time of the pulse valve i, so as to further divide the video segment into images, so as to obtain an air outlet image, wherein the air outlet image may be one or multiple.
For the one or more air outlet images acquired during the opening of the pulse valve i, the control device 3 may count the average pixel gray values of the air outlet images; if the average pixel gray value exceeds the average pixel gray value of the reference image, determining that the dust removing cloth bag i corresponding to the pulse valve i is damaged. The average pixel gray value of the air outlet image may be the average pixel gray value of one or more air outlet images, and the average pixel gray value is used as the actual dust concentration measurement value of the dust collection cloth bag i corresponding to the evaluation pulse valve i.
The average pixel gray value of the reference image is used as a reference dust concentration measurement value, and when the actual dust concentration measurement value of the dust collection cloth bag i is larger than the reference dust concentration measurement value, the dust collection cloth bag i can be considered to be damaged. The reference image corresponds to the air outlet images when the N dust collecting cloth bags are not damaged, and the reference image can be acquired in advance.
In addition, in order to visually see the damage condition of the dust removing cloth bag, optionally, the dust remover detection system further comprises: and the alarm device 4 is arranged on the bag-type dust collector body 1, the alarm device 4 is connected with the control equipment 3, and the control equipment 3 is used for sending an alarm signal to the alarm device 4 when determining that the dust collection bags i in the N dust collection bags are damaged so as to prompt the damage of the dust collection bags i. Optionally, the alarm device 4 comprises: and the display screen and/or the voice player, so that the damage notification of the dust collection cloth bag can be performed in the form of screen display or voice broadcasting.
Alternatively, the alarm device 4 can also be arranged in the control device 3, i.e. on the control device 3 side, to give an alarm about damage to the dust bag.
Alternatively, the dust concentration detector 2 may be disposed in the upper case 13 in such a manner that: the dust concentration detector 2 is adsorbed on the inner wall of the upper box 13 by a strong magnetic mode. The arrangement mode can be suitable for occasions with low temperature generated when the dust remover operates. It will be appreciated that in this arrangement, the upper housing 13 and the dust concentration detector 2 have cooperating magnetic coupling formations thereon.
Alternatively, the dust concentration detector 2 may be disposed in the upper case 13 in such a manner that:
The bracket 132 and the through hole 133 are arranged on the outer wall of the upper box 13, and the through hole 133 is matched with the camera 21 of the dust concentration detector 2. Thus, the dust concentration detector 2 is fixed to the bracket 132, and the camera 21 of the dust concentration detector 2 protrudes into the upper case 13 through the through hole 133. The arrangement mode can be suitable for occasions with higher temperature generated when the dust remover operates.
It should be noted that, regardless of the arrangement, the dust concentration detector 2 may be made of a material resistant to high temperatures, particularly the camera portion.
In addition, the dust remover detection system further comprises: an auxiliary light source 134 provided in the upper case 13. The auxiliary light source may include: an infrared light source and/or a visible light source. The visible light source is for example an LED lattice light source. The infrared light source allows the dust concentration detector 2 to take a clearer image. The visible light source can be suitable for under the scene such as the dust remover inside barrier is more, operating mode environment is narrow, can carry out the light filling to parts such as dead angle to dust concentration detector 2 beats better image.
Because the upper case 13 is in a dark environment during the operation of the dust remover, although the dust concentration detector 2 may be provided with an auxiliary light source required during shooting, in order to enhance the shooting effect, the dust concentration analysis in the image may be facilitated, the upper case 13 may be provided with the auxiliary light source 134, and the connection manner of the auxiliary light source 134 in the upper case 13 is not particularly limited.
