S4, according to the pressure value M of acquisition, the value M of calculatingn, pressure value PnPulse valve working curve is drawn with the value P of setting.
Specifically, deduster successively works since first unit, according to the pressure value M of acquisition, the value of calculating
Mn, pressure value PnPulse valve working curve is drawn with the value P of setting, that is, can determine whether the working condition of pulse valve.Below according to pulse
The working curve formed under valve different working condition is illustrated:
As shown in Fig. 2, 0.8≤M:M ought be met simultaneouslyn≤ 1.2 and 0.9≤Pn: when P≤1.1, the curve is formed, this clock pulse
It rushes valve and is in normal operating conditions.
It should be noted that value P is set according to production needs, and it is not limited to some particular value.
As shown in figure 3, working as M:MnWhen >=1.2, the curve is formed, indicates that deduster Unit n-th deashing tolerance is excessive, at this time
Need to adjust supply gas pressure or adjustment pulse valve film by pressure regulator valve, if deashing tolerance is still excessive after adjustment, to failure
Pressure regulator valve or pulse valve replaced or repaired.
It should be noted that then this takes turns the deduster cell operation number when pulse valve is in the abnormal operation
It is not counted in q, and does not calculate Mn, and with the M of last round of calculatingnInstead of.
As shown in figure 4, working as M:MnWhen≤0.8, the curve is formed, indicates the deduster pulse valve of Unit n-th failure or non-work
Make, needs to check current PRF valve electric-control system and pulse valve film at this time, the component of failure is replaced or repaired.
As shown in figure 5, working as Pn: when P >=1.1, the curve is formed, indicates that current supply gas pressure is excessive, needs to adjust at this time
Supply gas pressure.
As shown in fig. 6, working as Pn: when P≤0.9, form the curve, indicate the pulse valve film gas leakage of deduster Unit n-th or
Supplement gas source is less than normal, and needing to check whether there is pulse valve at this time, there are foreign matter or failures, and foreign matter is then cleared up in time if it exists, if therefore
Barrier is then replaced or is repaired.
Preferably, before S1 further include:
S0, gas storage packet and pipeline pressure P before deduster works are obtained0, and be compared with the P value of setting, if 0.9≤P0:
P≤1.1 then execute S1.
Preferably, S0 further include:
If P0: P≤0.9 then checks whether pressure regulator valve modulated pressure reaches setting value or whether pipeline leaks.
It should be noted that needing to check the supply gas pressure P of system before deduster work0It is whether normal, if abnormal, i.e. P0:
P≤0.9 then illustrates that pressure regulator valve modulated pressure is not up to setting value or pipe leakage, needs to arrange staff at this time and tie up
Shield, after abnormal conditions exclusion, deduster is started to work.
