What is the boiler dust removal equipment?
What is the boiler dust removal equipment? There are many types of dust removal equipment. At present, the general models in our market are: bag dust removal equipment, pulse filter dust collector, stand-alone dust collector, workshop dust removal equipment, wet dust collector, cyclone dust collector, sander. Vacuuming workbench, industrial vacuuming equipment, etc.
What kind of dust removal equipment is generally used for boiler dust removal equipment?
Boiler dust removal equipment currently has a large proportion of bag dust removal equipment in the market. Yuchen Industrial Dust Remover Equipment Manufacturers today talk about the design and operation data of bag dust collectors in boiler processing.

： 锅炉除尘设备滤袋的清灰设计 3 : Dust removal design of filter bag of boiler dust removal equipment
Filter bag cleaning Each pulse chamber has its own pulse cleaning system. The system consists of an air bag and several pulse valves, and a blowing pipe on the top of each row of filter bags. Compressed air is sprayed down into the venturi located at the top of each filter bag through a small hole in the blow pipe. The operation of the pulse valve is controlled by a solenoid valve, and the duration and frequency of the solenoid valve energization are controlled by a timer. Dust removal can be started automatically or manually. DCS 向定时器发出信号，从而对各行滤袋顺序脉冲。 In order to extend the life of the filter bag, offline cleaning is adopted. The cleaning starts when the outlet isolation valve of a compartment is closed, and then the DCS sends a signal to the timer to sequentially pulse the filter bags in each row. There is a rest time after all the filter bags in the compartment are pulsed, so that the smoke and dust that have separated from the filter bags fall into the ash hopper. . Then reopen the outlet valve and resume filtering. Each compartment will be off-line for about minutes .
What kind of protection system for boiler dust removal equipment?
度的时候，就立刻发出报警警报，达到 190 度时发出更高的警报，达到 205 度时发现特级警报，这时锅炉除尘设备的保护系统自动打开，保护系统一般叫做旁通，设计旁通的目的防止滤袋损坏。 The boiler dust removal equipment protection system may have an emergency during the operation of the boiler. One of the reasons that will damage the filter bag is high temperature. When the flue gas temperature of the dust collector equipment reaches 175 degrees, an alarm will be issued immediately, reaching 190. A higher alarm is issued when the temperature reaches 205 degrees, and a special alarm is found when the temperature reaches 205 degrees. At this time, the protection system of the boiler dust removal equipment is automatically opened. The protection system is generally called a bypass. The purpose of the bypass is to prevent filter bag damage.
