In the design of dust removal equipment, it is very important to choose the type and parameter settings of the pulse bag dust collector properly. It not only affects the use of the dust removal equipment, but also affects the service life of the dust removal equipment. Therefore, it has important significance. What are the parameter settings for the selection of the pulse bag filter?
Pulse bag filter selection parameter setting 1. Selection of filtering speed. Filtration speed is a key factor in selecting a pulse bag filter. It should be determined according to the characteristics of smoke or dust, application conditions, dust particle size, viscosity, gas temperature, moisture content, dust concentration, and different filter materials. When the particle size of the dust is relatively 5m / When thinner, relatively high temperature and humidity, higher concentration, and relatively high viscosity, low values should be selected. For example, 1m / min or less; on the other hand, high values can be selected, which should generally not exceed 1.5m / minute. For dust with large particle size, normal temperature, dry, non-sticky and extremely low concentration, 1 is optional. 5-2. m / min.
Pulse bag filter selection parameter setting 2. Filter material. Should be considered according to the temperature of the dust-containing gas, water content, acidity and alkalinity, viscosity, concentration, and peckability of dust. Generally speaking, when the water content is small and there is no acidity, select according to the temperature of the dust-containing gas. At room temperature or 13.0 ° c or lower, 500-550 g / m2 polyester needle felt is usually used. When <250 ° C, aramid Nomex needle felt or 800g / m2 glass fiber needle felt or 800g is used. / m2 weft double glass fiber fabric or FMS [FMS] high temperature filter.
Pulse bag filter selection parameter setting 3. Controller. The pulse bag type dust collector adopts PLC microcomputer programmable controller for dust removal control, which is divided into three control modes: constant pressure (automatic), timing (automatic) and manual. Constant pressure control: control according to the set pressure difference, the pressure difference of the vacuum cleaner exceeds the set value, each chamber automatically removes dust one by one. Timing control: according to the set time, every other cleaning cycle, each The rooms are cleaned once in a row ... Manual control: You can perform manual control on the on-site operation cabinet to automatically clean the ashes of each room in turn, or clean the ashes of each room individually. The control mode is selected by the user. When the user does not require it, the supply is controlled according to the timing.
In the design of the pulse bag filter, the filtering wind speed is a very important parameter. However, various factors should be considered in the selection process.
Design of setting parameters of pulse bag filter:
