詰り判定方法を提供することを目的とする。In order to maintain the performance of the bag filter result U1 machine having an electric fan and a bag filter, the clogging of the bag filter must always be kept below a permissible value. For this purpose, it is necessary to constantly monitor the clogging state of the bag filter. Various techniques for monitoring the clogging status of bag filters have been proposed in the past, one of which is to install pitot tubes that can measure the static pressure on the inlet and outlet sides of bag filters, so that maintenance personnel can monitor them periodically. There is a technique of reading the differential pressure between the static pressures on the inlet and outlet sides using the pitot tube or the like when the bag filter is circulated, and determining the clogging state of the bag filter based on the read value. In addition, regarding the technology to maintain the performance of dust collectors,
As shown in Japanese Patent No. 4-114404, the internal pressure of the dust collector is detected, and the opening degree of the damper and the rotation speed of the fan are controlled based on the detected value, and the throughput mrit is adjusted according to the processing gas condition. A ventilating device designed to increase the airflow rate has been proposed. (Problems to be Solved by the Invention) However, when determining the clogging state of the bag filter using the conventional method, there are the following problems. That is, a pressure detector such as a pitot tube has been used to measure the differential pressure, but it is difficult to accurately measure the differential pressure between the inlet and outlet sides of the bag filter due to clogging with dust, etc. Maintenance and inspection of the pitot tube itself takes effort. In addition, the differential pressure between the inlet and outlet sides of the bag filter varies greatly depending on the dust collection process ff1ffl in addition to clogging of the bag filter, and it is difficult to determine whether the bag filter is clogged by simply measuring the differential pressure. Have difficulty. Furthermore, maintenance personnel must visit regularly to inspect and maintain the bag filters, which is labor-intensive. The ventilation device proposed in the above-mentioned Japanese Patent Application Laid-Open No. 54-114404 maintains the dust collection ability by adjusting the ventilation amount, but it is not possible to easily detect and determine the clogging state of bag fill. has not yet been reached. (Objective of the Invention) The present invention has been made to solve the above-mentioned conventional problems, and the dust collection flow rate fluctuates without detecting the static pressure difference between the inlet and outlet sides of the bag filter. To provide a method for determining clogging of a bag filter, which can accurately determine the clogging state of a bag filter even when the bag filter is clogged.

The above object is achieved by comparing the detected parameter with the upper limit value of the parameter, and determining the clogging state of the bag filter based on the comparison result. (Function) In the present invention, when determining the clogging state of the bag filter of the dust collector, a parameter indicating the operating state of the electric fan of the dust collector is detected, and the dust collector yJ of the dust collector is detected.
The detected parameter is compared with the upper limit value of the parameter determined by the air outlet and allowable pressure loss, and the clogging state of the bag filter is determined based on the comparison result. Therefore, it is possible to accurately determine the clogging state of the bag filter without detecting the static pressure difference between the inlet and outlet sides of the bag filter (even if the dust collection process ff1ffl fluctuates).
If the dust collecting device is properly controlled and maintained according to the determined clogging state, it is possible to prevent the image collection ability from decreasing. Further, since it is not necessary to detect a static pressure difference, the clogging state can be determined without using a pressure detector such as a pitot tube, and therefore maintenance of the pressure detector is not required. Furthermore, since the clogging state can be automatically determined, there is no need for regular visits by maintenance personnel required for maintenance of bag filters, and therefore, the labor required for maintenance can be significantly reduced. Therefore, it greatly contributes to cost savings. Note that the parameter indicating the operating state of the electric fan may be, for example, input power, input current, or rotation speed of the electric fan.

The present invention is applied to a device for determining the clogging state of a bag filter 10 of a bag filter dust collection basin, which is equipped with an electric motor 16 for rotating a bag filter dust collection bin. In this embodiment, an air volume detector 18 for detecting the air volume actual value Q of the dust collection ff 114, the detected wind volume actual value Q and a preset wind volume target value Qx are inputted, Each input ff
1fflQ, Q'' is used to perform processing such as feedforward calculation and integral calculation, and the target value Qx and actual value Q of air volume are calculated.
a computing unit 20 for calculating the rotational speed of the fan such that the values coincide with each other; and a speed change means 2 for adjusting the rotational speed of the forced-in fan 12 based on the calculated rotational speed value.
2, and the electric motor 16 for the detected air outlet performance value Q.
an upper limit value calculator 24 for calculating the upper limit value P max of input power to
x and the current input power P of the electric machine 16 ([parameter indicating the operating state of the electric fan] in the claims)
an alarm device 28 for automatically issuing an alarm when it is determined from the comparison results that the clogging state of the bag filter 10 exceeds an allowable value.
and will be provided. Note that 30 in the figure is a conduit for guiding the dust-collecting air 14 to the forced fan 12. The present embodiment is configured as described above, and the forced fan 12 is controlled so as to achieve the rotational speed calculated by the calculator 20, so that the actual value Q of the dust collection air j can be adjusted to the target air ff1Q as much as possible.
can be matched with In addition, the clogging state of the bag filter 10 can be accurately determined at any air outlet without measuring the differential pressure between the inlet and outlet sides of the bag filter 10, and the clogging state can be automatically determined based on the determined clogging state. This makes it possible for the alarm device 28 to issue an alarm at any time. Note that the detection of the actual value Q of the air outlet is not limited to direct detection using the air outlet detector 18, but also by measuring the input power to the electric motor 16 and the rotational speed of the forced fan 12, and from these measured values. It is also possible to estimate by calculating the wind mouth performance value Q. Next, a method for determining the input power upper limit value p_wax will be explained using FIG. 2. The same figure (A) shows a curve showing an example of the relationship between the static pressure H of the forced fan 12 and the wind ff1Q (indicated by symbols H+ and N2), and a curve showing an example of the relationship between the resistance of the conduit 30 and the air volume Q (indicated by the symbol L+). , Lz). Further, FIG. 2B is a curve (indicated by symbols L3 and L4) showing the relationship between the wind ff1Q and the input power P. In addition, Kazaguchi Q
The values of the static pressure, pipe resistance, and input power P for
It takes a value on the curve L3, and when the rotation speed is N2, it takes values on the curve L2, N2, and L4. Now, bag filter collection I with air volume Qo! Consider the case of driving IIm. If the bag filter 10 is not clogged, and the rotational speed of the forced fan 12 is constant, Mfl
Assuming that the pipe resistance against Q changes like a curve, not shown by the symbol @L+ in the figure, the forced fan 12 passes through point A on the static pressure curve shown by the symbol H1 so that the static pressure H and the pipe resistance are balanced. is driven by. In addition, the input power P to the electric motor 16 at this time is based on the wind f on the curve indicated by the symbol L3 in FIG.
The input power value P1 at point C corresponds to iltQO. Note that when the air outlet Q is adjusted by controlling the rotational speed of the forced fan 12, the shaft power of the forced fan 12 is approximately proportional to the cube of the above-mentioned ff1f2iQ, and therefore the input power P is approximately proportional to the cube of ItMiQ. Since it is proportional, the relationship between input power P and ff1fflQ becomes a curve as shown in the figure [3]. Next, consider a case where the clogging of the bag filter 10 progresses and the clogging reaches the permissible limit, and the pipe resistance against the wind ff1Q becomes a curved line, not indicated by the symbol L2 in FIG. think. In this case, since l1tQ is controlled to be a constant value Qo, the rotational speed of the forced fan 12 is automatically increased, and the static pressure H of the forced fan 12 is increased by the symbol H in the figure.
The rotational speed increases so as to increase the pressure until it passes through point B on the curve shown by 2. The input power at this time becomes the value P2 at point D on the curve indicated by the symbol L4 in FIG. When the rotational speed increases as described above, the relationship between the input power P and the wind ff1Q when the wind fAQo is successively changed becomes the curve indicated by the symbol L4, so that the clogging of the bag filter 12 reaches its limit. The relationship between the wind mQ and the input power P when the rotational speed of the forced fan 12 is controlled in this state so that the wind IQ becomes a constant value is determined in a simple manner as shown by the curve L4. Therefore, if the power value on the curve with the symbol L4 is set in the comparator 26 in advance as the upper limit value p wax of the input power for each wind ff1Q, the bag filter 12 compares the input power with the set upper limit value Pfflax. The clogging status can be determined. In setting the upper limit ta P 1Dax of input power, the power cost consumed when driving the forced fan 12 and the inspection, cleaning, maintenance, and
It can be set at an appropriate value in consideration of the balance with various costs such as replacement. In the above embodiment, the input power to the electric fan 16 was used as a parameter indicating the operating state of the electric fan for detecting the allowable limit of the clogging state of the bag filter.
The parameters used when implementing the present invention are not limited to this input power, but other parameters such as input current to the electric motor, rotational speed of the forced fan, etc. can be used, and by detecting this parameter, It is possible to obtain the effects of the present invention in a similar manner. Further, in the above-mentioned embodiments, the present invention is applied to a clogging state determination device having the configuration as shown in FIG. It is clear that the present invention is not limited to the configuration shown in the drawings, and that the present invention can be implemented with a clogging state determining device having other configurations. Effects of the Invention As explained above, according to the present invention, the bag filter can be accurately monitored even if the dust collection air flow rate fluctuates without detecting the static pressure difference between the inlet and outlet sides of the bag filter. The excellent effect of being able to determine the clogging state can be obtained.
