Description

SMCOKE-REMOVING EQUIPMENT FOR THERMAL POWER GENERATION
Technical field
The invention relates to the technical field of smoke removal equipment, in particular to smoke removal equipment for thermal power generation.
Background Technology
Utilized during thermal power generationCombustiblesAtBurnThe heat energy generated at the time ofPower generation power plantConvert toElectrical EnergyThe basic production process is as follows: fuel is burned in a boiler to heat water to generate steam, the chemical energy of the fuel is converted into heat en-
ergy, the steam pressure drives a steam turbine to rotate, the heat energy is converted into mechanical energy, and then the steam turbine drives a generator to rotate and converts the me- chanical energy into electric energy.
However, a large amount of smoke will be produced in the process of power generation.
Smoke and dust is the solid particles suspended in the gas formed in the thermal process of oxidation, sublimation, evaporation and conden- sation, which is called smoke and dust.
For example, the converter flue gas contains a large number of extremely fine smoke and dust.
The area with serious desertification will roll up a large smoke storm when it is blown by a strong wind.
At present, the treatment method is desulfurization and denitrification device to reduce the concentration of compounds in the discharged smoke.
Secondly, the height of the chimney is a key, which depends on the size of the installed capacity.
Generally, the height of the chimney should be higher than 200 meters for units with more than 300000 kilowatts for power generation, so as to ensure that the smoke and dust dis- charged are far enough from the ground and that the speed of land- ing slows down.
Of course, in the process of emission, the way of heating the smoke and dust by hot air from the fan also ensures that the speed of landing slows down.
However, it is impossible to guarantee 100% complete combustion of fuel in the combustion pro- cess, so there are fine fuel particles in the smoke and dust, so it is also very important to deal with the smoke and dust before desulfurization and denitrification. On the other hand, even if the distance between smoke and dust discharge and the ground is far enough to ensure slow dust fall, the smoke will still pollute the atmosphere. A smoke removal apparatus for thermal power gener- ation is proposed to solve the above problems.
