The environmental problem faced by large boiler manufacturing enterprises is incomplete desulfurization and dust removal. Previously, most dust removal equipment caused problems with secondary pollution. The generation of secondary pollution was also annoying. However, with the gradual development of dust removal equipment, dust removal equipment has also followed Development. There are two types of large boiler dust collectors : Venturi dust collector and electrostatic dust collector.
The electrostatic precipitator is an electrostatic precipitator. This method has the advantages of good dust removal effect, small resistance, low power consumption, etc. Its disadvantages are large floor area and large investment, which are mainly used for large boilers.
Principle: The high-voltage electric field is used to ionize the work of the electrostatic precipitator of the flue gas, and the electric field of the flowing charge is separated from the air. The cathode is made of metal wires with different cross-sections, called discharge electrodes. The positive electrode is made of metal plates of different geometries and is called a dust collecting electrode.
There are two types of large-scale boiler dust collectors. The performance of an electrostatic precipitator is affected by dust characteristics, equipment structure, and flue gas flow rate. The dust resistivity is an indicator of electrical conductivity and directly affects the dust removal efficiency. Under the resistance, dust particles cannot remain in the The vacuum cleaner causes it to return to the air. The specific resistance is high, the dust particles on the vacuum cleaner are not easy to release, and the voltage gradient between the dust layers will cause local breakdown and discharge. These conditions will lead to reduced dust removal efficiency.
