Description
Technical Field
The utility model belongs to the technical field of thermal power generation fans, and particularly relates to a novel thermal power generation fan.
Background
Thermal power generation is a power generation mode that uses heat energy generated when combustible materials are combusted, and converts the heat energy into electric energy through a power generation device. However, the insufficient combustion of coal can generate a large amount of solid dust, which causes pollution to fly ash in the environment near the power station and has adverse effects on the life of people and the growth of plants. The solid dust generated during coal combustion can be fighted in each device of a heat supply system, the heat supply performance is easy to be reduced, six fans, namely a blower, a primary fan, a draught fan, a booster fan, a sealing fan and a dilution fan, are needed to be used in a boiler of a thermal power plant, wherein the blower is used for providing secondary air, and after the secondary air passes through an air preheater, part of the secondary air is used for providing perimeter air, sandwich air and the like to a burner, so that flames at the burner are influenced, and the burner can be cooled. The other part provides the amount of oxygen required for boiler combustion. And finally, providing SOFA and COFA air, adjusting combustion, and providing primary air by a primary air blower (taking a medium-speed coal mill and a direct-fired pulverizing system as examples), wherein the primary air blower is divided into two paths from the air blower, one path is called hot primary air after passing through the air preheater, and the other path is called cold primary air without passing through the air preheater. The hot primary air provides drying output and ventilation output for the coal mill, and the pulverized coal ground by the coal mill is dried and then carried into the boiler burner. The cold primary air and the hot primary air are mixed at the inlet of the coal mill, so that the effect of adjusting the inlet and outlet temperature of the coal mill is achieved, and the cold primary air and the hot primary air are part of ventilation output of the coal mill. The induced draft fan is used for pumping out the flue gas of the boiler and maintaining the negative pressure of the boiler. The flue gas enters an induced draft fan after electric dust removal of the air preheater, and the induced draft fan sends the flue gas into a desulfurization system or directly discharges the flue gas into a chimney.
(4) And the booster fan is characterized in that one path of wind from the induced draft fan enters the booster fan, and the other path of wind enters the chimney through the bypass. (the bypass is not allowed to be opened when the generator set normally operates, otherwise, the flue gas which is not subjected to desulfurization is environment-friendly and does not reach the standard, and the flue gas is allowed to be opened only when an accident occurs in the desulfurization system), the wind from the booster fan enters the desulfurization system to desulfurize the flue gas and then is discharged into a chimney, and the sealing fan is used for taking the wind source from a cold primary wind pipeline. The sealing fan is used for providing sealing air for the coal feeder and the coal mill, wherein the sealing air of the coal mill is divided into a grinding roller, a grinding bowl, a loading spring and the like, and the dilution fan is basically not used for the former unit because the fan is used for providing unit denitration and is used for providing air for a denitration system to dilute ammonia.
The air feeder provides enough burnt air for the burner to maintain stable combustion, the existing air feeder does not have the function of deep filtering the air in the air feeding process, and most of the air feeder filters impurities, dust and particulate matters in the air in a filtering mode, but in the process, tiny dust or impurities enter the equipment, long-time accumulation influences the operation of the equipment, and the impurity dust contained in the air is more unfavorable for the full combustion of fuel in the burner, so that a novel thermal power generation fan is provided.
