Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly relates to a device for removing caking ash blockage in a smoke cooler. Background Art

[0002] During the operation of a thermal power plant, impurities such as fly ash and desulfurization products generated by coal combustion in the flue are likely to adhere to the inner wall of the flue, as well as the surfaces of the guide vanes and support structures, and gradually accumulate to form ash scale. After the ash accumulation reaches a certain level, it will cause a reduction in the flow area of the flue, an increase in the flue gas resistance, a decrease in the operating efficiency of the unit, and an increase in energy consumption; in severe cases, it may even cause a flue blockage, affecting the safe and stable operation of the unit.

[0003] Most domestic large-scale coal chemical projects use coal-fired boilers as the power source for the whole plant. The power of the chemical plant is provided by a circulating fluidized bed coal-fired boiler. After the boiler operates continuously and normally for a period of time, it is prone to MFT interlock trip events caused by instantaneous overpressure in the furnace. After investigation and research, it is found that the ash accumulation in the tail flue accounts for 1 / 3 of the net flow channel, and the ash accumulation in some parts is even more serious, becoming a great hidden danger to the safe and stable operation of the boiler.

[0004] Currently, the commonly used flue ash cleaning solutions are acoustic ash cleaning, or cleaning by spraying chemical agents, or simply blowing the accumulated ash away by the flue gas velocity. The above ash cleaning methods all have the disadvantage of incomplete ash cleaning. Since the flue gas in the flue contains a large amount of dust before formal dust removal, after long-term operation, it is still prone to ash accumulation. The generated accumulated ash cannot be sent away in time and can only be carried away by the flue gas. At different positions in the flue, the ash accumulation is serious and easy to accumulate and cake. Eventually, it will cause the flue to bear too much load, easily causing deformation and strength damage to the flue; at the same time, it will increase the flue resistance, cause wear of the fan, and the existing technology cannot achieve efficient and non-destructive removal of ash accumulation in complex flue structures (such as variable diameter sections). There is an urgent need to develop a new type of removal device that can be applied to different pipe diameters and different inner wall structures and has good ash cleaning effect.

At this time, the positions of the respective swinging ends are also different. It should be noted that the swinging ends are always in contact with the end of the sliding rod 521, so that the cleaning plate 513 can be applied to flue 1 environments with various shapes and structures for cleaning. By adopting the way of swing limit and the split cleaning plate 513, the overall applicability is further improved, thereby improving the cleaning effect.
