Description

Fluffy sediment cleaning device suitable for arrange sediment system futilely

Technical Field

The utility model belongs to the technical field of power boiler row sediment, concretely relates to fluffy sediment cleaning device suitable for dry row sediment system.

Background

Under the environment of 'carbon peak reaching and carbon neutralization', the current international situation is complex and changeable, the domestic energy demand is short, the coal price is greatly increased, the current thermal power plant is greatly damaged, and the development prospect of the thermal power plant is not optimistic. In order to maintain development and reduce loss, most thermal power plants select to participate in power grid wide load peak shaving or select low-price low-heat coal types, but participation in power grid wide load peak shaving means that unit load can change frequently, and even fluctuate greatly when the thermal power plants are put into a frequency modulation ACE mode, so that the problems of boiler combustion disturbance, insufficient combustion, rapid increase and decrease of heat storage capacity and the like can be caused, and boiler coking and decoking are easily caused; meanwhile, the selection of low-price and low-heat coal types means that the quality of coal as fired of the boiler deviates from a designed value, and due to the deviation from the designed coal types, the characteristics of coke residues and the combustion characteristics of the low-price and low-heat coal types are not satisfactory, so that flame coal powder erodes a water-cooled wall even if the adjustment is manually intervened, the problems of coking and coke dropping of the boiler and the like are caused. The bold that the boiler coking leads to falls burnt at first breaks the slag well by a crashing object easily, and secondly, the side wall of boiler falls burnt and need pass through the buffering of curb plate from the slag well discharge, but when the curb plate, a large amount of coal cokes bond with the curb plate easily, form fluffy sediment, and fluffy sediment too high can lead to the slag well to block up, and the sediment position risees, seriously threatens unit safety. Therefore, timely boiler deslagging is needed, but in the prior art, the boiler deslagging is performed manually, the deslagging efficiency is low, and certain potential safety hazards exist for personnel.
