Electrostatic dedusting equipment for thermal power plants is an indispensable auxiliary equipment for thermal power plants. Its role is to remove particulate smoke from the flue gas emitted from the furnace or oil-fired boiler, thereby greatly reducing the amount of flue gas emitted into the atmosphere. This is an improvement Important environmental protection equipment for environmental pollution and air quality.
工作原理： Working principle of electrostatic precipitator in thermal power plant :
When the flue gas passes through the flue in front of the main structure of the electrostatic precipitator, the flue gas is positively charged, and then enters the passage of the electrostatic precipitator equipped with a multilayer cathode plate. Due to the mutual adsorption of the positively charged smoke and the cathode plate, the flue gas The particles of soot are adsorbed on the cathode, and the cathode plate periodically strikes, so that a certain thickness of soot falls into the ash bucket under the structure of the electrostatic precipitator under the dual effects of self-weight and vibration, so as to achieve the purpose of removing the soot in the flue gas.
As the power generation capacity of thermal power plants is usually relatively large, such as 600,000 kilowatts, coal consumption is about 180 t per hour, the amount of smoke and dust can be imagined. Therefore, the corresponding electrostatic precipitator structure of thermal power plants is relatively large. The cross section of the main structure of the dust collector is about 25 ~ 40 × 10 ~ 15m. If the height of the 6m ash bucket and the height of the flue gas transportation space are increased, the total height of the electrostatic precipitator is more than 35 meters. For such a large steel structure body, not only Consider the static and dynamic analysis under self-determination, smoke, wind, and seismic loads, as well as the stability of the structure.
The choice of supporting power supply for electrostatic precipitator equipment in thermal power plants is too large, which not only increases the initial investment, but also reduces the power and the dust removal efficiency due to the poor cooperation between the power source and the main body. The reasons are as follows.
If the voltage is too high, because the voltage applied to the electric field is related to the structure of the electric field and the working conditions of smoke and dust, the ideal effect cannot be achieved under a certain distance between the poles. For a power supply unit using phase voltage adjustment, if The voltage level is too high, when the electric field breakdown voltage is very high, it can be in a fully conducting state, and the average value of current and voltage is very high. However, when the breakdown voltage is reduced, the power supply voltage is reduced, and the electric field will generate spark discharge. Causes the average value of power supply voltage and current to drop significantly. However, if a low voltage unit is used for power supply, when the electric field voltage drops, it will still work in a fully conductive state. In this case, cells with lower power supply voltage levels will get a much larger average voltage and current than cells with higher power supply levels.
