Introduction of boiler
The dedusting equipment used for boiler dedusting includes mechanical dust collector, Bag Type Dust Collector, electrostatic precipitator and Wet Dust Collector. However, each dedusting and purifying system has its technical advantages and disadvantages. Appropriate dust removal facilities and processes should be selected according to the actual situation. A mechanical dust collector usually refers to a device for separating particles from airflow by the use of mass force (gravity, inertia force and centrifugal force). It includes gravity settling chamber, inertial dust collector and Cyclone Dust Collector. The bag type dust collector is a dusty gas from the bottom into the cylindrical filter bag. In the pore of the filter material, the dust is arrested and collected on the filter material. The cleaner air through the filter material is discharged from the outlet. The dust deposited on the surface of the filter material can be removed from the filter material surface under the action of mechanical vibration and eventually fall into the ash bucket. Dust purification facilities. Electrostatic precipitator (ESP) is a kind of dust removal equipment which separates dust particles from dust gas in the process of high voltage electric field, which makes dust particles charged and under the action of electric field force. The wet dust collector is a kind of dust removal equipment which makes dust gas in close contact with liquid (generally water), and uses the inertial collision or chemical action of water droplets and particles to collect particles, so that the dust is separated from the dust gas.
performance index It includes dust removal efficiency, pressure loss, handling gas quantity and load adaptability. 1. The efficiency of dust removal is generally used as an index in the design of dust removal engineering, and sometimes it is also expressed by classification efficiency. (1) the total efficiency and total efficiency are the percentage of dust and the amount of dust entering. (2) if the total efficiency is in the dust removal system, if the dedusting efficiency is 1, the ETA 2... The N precipitator will operate in series. The total efficiency of the dedusting system is expressed by means of ET. the calculated value of ETA = (1- ETA 1) (1- ETA 2) is (1- ETA n).
(3) the penetration rate of penetration rate is the percentage of the discharge of the dust in the outlet and the intake of the entrance dust by the press formula: (4) the classification efficiency n is the dust removal efficiency of a dust collector for a particle size D or the particle size range delta D, as shown in the following formula
2. The loss of pressure loss is the difference between the absolute value of the total pressure of the air flow at the inlet and outlet of the dust collector, indicating that the gas flow through the mechanical energy consumed by the dust collector can be calculated by the next formula when the local resistance coefficient of the precipitator is known. It can be measured directly on the site with a pressure gauge. The pressure loss of the medium p--------- dust remover, the density of u---, the density of gas, Pa, kg/m3, and the velocity of air at the entrance of the dust collector, m/s. 3. The size of the gas capacity to deal with the gas deduster is generally expressed in volume flow (m3/h or m3/s) and also of mass flow (kg/h or kg/s). 4. When the adaptability of the load adaptable load is good, the stable dust removal efficiency, moderate pressure loss and high operating efficiency can still be held when the quantity of gas or the concentration of pollutants is fluctuated in a large range.
