When it comes to design boiler bag filter dust removal device deployment, understand the boiler dust removal industry friends should not be unfamiliar, but maybe there are some people do not understand. Next, the design of the boiler tripod designer bag filter equipment deployed to introduce you to. 1, the low pressure side impulse precipitator spray air volume penalties disposal: Disposal penalty refers wind volume of dust that can set the device to deploy a purge gas within the unit time. Means cubic meters (m3 / h) standard cubic meters per hour or per hour (Nm3 / h). Dust is one set of equipment deployment plan most stressful factors. 2, with the temperature: set the device against dust deployments that use temperature depends on two factors, the first filter is subjected to the highest temperatures, the second temperature of the gas must be above the dew point. Now, since a large selection of filter glass, which is the maximum use temperature up to 280 deg.] C, the temperature of the gas must be higher than the receiving cooling step, the temperature of the gas below the dew point temperature must be connected Cincinnati pace. Set precipitator equipment deployment, the use of temperature and dust stakeholders obedience is not significant, this difference in ESP, for ESP, the temperature change will affect specific resistance of dust and other effects of dust obedience. 3, pressure loss: precipitator equipment provided deployment pressure loss refers to the gas inlet to the outlet from the filter pressure drop, or said resistance. 4, actuation pressure: ESP set up equipment deployment and actuation pressure is static pressure fan placement and location of the device before and after the dust and given credentials, but also the dust collector equipment deployment plan set pressure value. 5, filtration rate: the filtration rate is planned to select and filter settings and equipment deployment tensions, its explanation is filtered gas through the filter rate, presumably by air flow filter and filter area.
■Adopting a unique heating surface layout, boiler corrosion resistance performance enhancements, more secure and more reliable.
