Types and working principles of dust collectors for coal-fired boilers


The role of the coal-fired boiler dust collector is to deal with the problems of flue gas and dust generated by the boiler plant during coal burning. The boiler plant will generate large flue gas dust when burning coal. The coal-fired boiler dust collector can effectively solve these problems. There are many types of coal-fired boiler dust collectors on the market. What are the types and working principles of coal-fired boiler dust collectors ?

 

The types of coal-fired boiler dust collectors can be divided into the following:

 

1.Mechanical dust collector

 

The characteristics of mechanical dust collectors are simple structure, low cost and convenient maintenance, but the low dust removal efficiency has been gradually eliminated. Because it can not meet China's current environmental protection emission requirements, it is rarely used now!

 

Second, bag dust removal equipment

    

Bag filter is a widely used coal-fired boiler dust removal equipment on the market. Bag bag is used for isolation, which can handle a relatively large filtering area and can meet some stricter environmental protection requirements!

 

Third, wet dust collector

 

    Wet dust collectors use dust airflow to contact water or other liquids to capture dust particles. Such as Venturi dust collector, cyclone water film dust collector and so on. The washing type dust collector has high efficiency, simple structure, low cost, and also has the function of absorbing harmful gas, but it will produce sewage and sludge and need to be treated.

 

Fourth, the electric dust collector

 

The electric precipitator is a device that uses a strong electric field corona discharge to ionize the gas, charge the dust particles, and separate the dust particles from the air flow under the Coulomb force. The characteristics of the electrostatic precipitator are high dust removal efficiency, high temperature gas handling, low resistance and low operating cost, but high steel consumption, high cost and high technical requirements.


95% 以上,运行费用较低和环保排放标准提高,能达到提高后的新环保排放标准的要求。 Due to the large flue gas treatment capacity and low resistance of the electrostatic precipitator, it has good adaptability to the concentration of smoke and dust, can collect dust particles of various particle sizes, and has a dust removal efficiency of more than 95% . Able to meet the requirements of the new improved environmental protection emission standards. Therefore, although the initial investment is high and it occupies a large area, it has high requirements on the quality of manufacturing, installation and maintenance. Most of the large and medium pulverized coal furnaces use electrostatic precipitators.

Types and working principles of dust collectors for coal-fired boilers

 

用的除尘器主要运行原理就是用 “力”在对车间粉尘进行处理的,这个“力”就是指的就是:吸力、风力、阻力、清灰能力等几大方面,一个好的燃煤锅炉 除尘设备厂家,最基本的是对 “力”有着非常专业的算法! The main operating principle of the dust collector for coal-fired boilers is to use the "force" to treat the dust in the workshop. This "force" refers to: suction, wind, resistance, and dust removal ability. For coal boiler dust removal equipment manufacturers, the most basic is a very professional algorithm for "force"!
