Factors affecting the dust removal effect of the dust collector


Factors affecting the dust removal effect of the dust collector

但影响除尘器的除尘效果有那些因素.一般二次电压升不到额定值。 The dust collector has been widely used in industrial dust treatment , but there are those factors that affect the dust removal effect of the dust collector . Generally the secondary voltage rises below the rated value. 、电流10mA ,收尘效果最好,而此时手动或自动调升压电压升至40kV,或更低时,从仪表上便反映出有火花放电现象或听到噼啪声,电流、电压大幅度波动。 If the best working voltage is 70kV and the current is 10mA , the dust collection effect is the best. At this time, when the boost voltage is manually or automatically adjusted to 40kV, or lower, a spark discharge phenomenon is heard from the meter or heard Crackling, current and voltage fluctuate greatly. If the meter's indication is stabilized, the working current will drop to almost zero. At this time, the output power will be low, the electric field strength will not meet the requirements, and the dust collection effect will be poor.

、卧式除尘小于等于0.8m/s)发生摆动;原因之三是,芒刺极板发生变形,间距不一样,象这种情况,只有重新校正间距。 There are three reasons for this phenomenon. One of the reasons is that the plates and corona wires are excessively dusty and uneven, which causes the electrode gap to decrease, and local air breakdown. As long as you manually beat it a few times, you can Solved; the second reason is that during installation, the corona wire (burr) electrode plate is not reliable and is affected by the wind speed of the induced draft fan (vertical dust removal is less than or equal to 1.2m / s , horizontal dust removal is less than or equal to 0.8m / s) ; The third reason is that the burr plates are deformed and the spacing is not the same. As in this case, the spacing must be corrected again.

Neither the current nor the voltage changed significantly, but the dust collection effect deteriorated. The reason is that the distribution holes of the air distribution device are blocked or the guide device is moved, which causes serious uneven air distribution. There is almost no current at high voltages. 范围。 The reason is that the high-voltage damping resistor is broken or the specific resistance of the dust changes greatly, which has deviated from the range of 104 ~ 1011 . 的粉尘,对于高于1011的粉尘,多半发生在窑系统的除尘器上,如窑的废气温度增高,造成进入电收尘器内的粉尘干燥,比电阻增高,导致收尘效率降低。 Kilns and grinding systems in cement plants generally have no dust below 104. For dust above 1011 , most of them occur on the precipitator of the kiln system. For example, the temperature of the exhaust gas from the kiln increases, which causes the dust entering the electric dust collector to dry. Higher resistance results in lower dust collection efficiency. Damage to the rapping device will also increase the adhesion dust on the plate, which will cause the corona to close to a certain extent, resulting in no current.

The air volume of the kiln system is greatly adjusted, and the dust collector is unstable. The main manifestation is that the gas flow velocity, concentration, and temperature in the dust collector change rapidly, which makes it difficult to stabilize the electronic control. What is reflected is that the indicator indication is unstable and the pointer fluctuates frequently. If automatic constant current power control is used, the voltage will increase. The lower and lower, it will even be close to zero, causing the dust collection effect to deteriorate.

Insufficient sealing of the maintenance door on the cabinet will also reduce the dust collection efficiency, and the voltage will not rise even after restarting, especially the raw material dust collector of the vertical kiln cement plant, the airflow temperature is low and the moisture content is low. Large, if there is air leakage, it is very easy to cause dew condensation inside the dust collector, which will cause creepage phenomenon. This is manifested in the instrument that the voltage cannot rise, but the current is very large, and the dust collection effect is extremely poor. In this case, a small hot air stove should be installed in front of the dust collector inlet and the guide device. By heating and paying attention to the seal of the access door, the temperature of the dust gas should always be kept above the condensation temperature .
