Our company has been engaged in the production and installation of pulse bag dust collectors in chemical plants for many years, and has summarized rich experience in the use and maintenance of pulse bag dust collectors in chemical plants. In order to ensure the normal operation and prolongation of the service life of the dust collector, Sanrong Environmental Protection reminds everyone to use The unit carefully abides by the bag dust collector usage rules and maintenance instructions. The scope of application of dust collector accessories is suitable for dust removal equipment in cement plants, steel, smelting, chemicals, coal coking, casting, mining, carbon black, food, grain, woodworking and other industries. Single machine dust removal or system dust removal can be used. Single-machine dust removal is mainly used for dust removal on a single woodworking machine and is flexible and convenient. System dust removal is used for dust removal in woodworking machinery production lines. It is economical, practical, and beautiful. It does not affect production operations and can achieve ideal dust removal effects. Working Principle of Pulse Bag Dust Collector in Chemical Plant
, Filtration Principle
Dust-containing gas enters through the air inlet and collides with the inclined baffle. Most of the coarse dust in the gas is separated by the inertial force and directly Fall into the ash bucket. After the dust-containing gas passes through the ash hopper, it enters the filter bag filter area of the middle box. The gas passes through the filter bag and the dust is blocked outside the filter bag. The purified gas enters the upper box through the filter bag mouth and is then discharged from the air outlet.
Principle of dust cleaning
As the filtration time continues, the dust layer on the filter bag continues to accumulate, and the resistance of the dust removal equipment continues to rise. When the equipment resistance rises to the set value or the operating time reaches the set value, value, the dust cleaning device starts cleaning. In order to ensure that the resistance of the dust collector is controlled within a certain range, the pulse controller sends a signal to sequentially open the electromagnetic pulse valve, so that the compressed air in the air bag is sprayed from each blowing hole of the blowing pipe to the corresponding venturi tube (called When the high-speed airflow passes through the venturi, the primary wind induces the surrounding air (called secondary air) that is several times the primary wind to enter the filter bag, causing the filter bag to expand, deform and vibrate, and is attached to the filter bag under the action of reverse airflow erosion. The dust on the outer surface of the filter bag is peeled off and falls into the ash hopper. After the dust cleaning is completed, the electromagnetic pulse valve is closed and the filtering state is restored. The dust cleaning of each blowing pipe is carried out in sequence, from the first dust cleaning to the next dust cleaning. A cleaning cycle.
, Dust collection
The dust trapped by filtration and cleaning will fall into the ash hopper, and then be discharged from the ash hopper mouth through the ash discharge valve, etc.
, operation and dust cleaning control
The operation and dust cleaning of the pulse injection bag dust collector are controlled by a universal industrial automation system (programmable controller). There are two control modes: manual and automatic. Automatic in automatic mode program to complete the dust removal operation and cleaning process. Use manual control during maintenance or debugging for dust removal operation and automatic control for dust cleaning.
The dust cleaning control method can use either the timing method or the fixed resistance method. .
The timing method is to clean the dust row by row according to the set time program.
The constant resistance method is to use a pressure difference transmitter to convert the pressure difference signal inside and outside the filter bag into an electrical signal and transmit it to, Monitor the pressure difference. When the pressure difference signal is greater than the set value, the dust collector is controlled according to the set program to clean the dust row by row.
