Problems solved by technology

The wet scraper slag removal machine needs to consume a certain amount of water, the equipment structure is relatively complicated, and problems such as water explosion and water leaching of slag may occur during operation; and the comprehensive utilization value of the bottom slag is low, and the chemical energy of unburned carbon in the slag is not large enough. Can be effectively utilized, the physical sensible heat in the bottom slag is wasted
The air-cooled dry slag discharger has poor adaptability to changes in boiler slag volume, complex equipment structure, high failure rate, boiler bottom air leakage reduces boiler efficiency, and the chemical energy of unburned carbon in slag cannot be effectively utilized
[0003] The current boiler energy recovery method is generally to recover the waste heat in the boiler flue gas, while the heat in the bottom slag of the boiler is not used, which makes the energy utilization rate of the boiler low and causes a waste of energy

Abstract

The invention discloses a boiler high-temperature bottom residue conveying device and a boiler high-temperature bottom residue energy recycling method. The boiler high-temperature bottom residue conveying device and the boiler high-temperature bottom residue energy recycling method are characterized in that the conveying device (2) comprises a plurality of integrally-connected moldboards (3) and moldboard shafts (4), one ends of the moldboard shafts (4) are movably connected to a base board of a shell (1), the other ends of the moldboard shafts (4) are fixedly connected with the lower surfaces of the moldboards (3), the moldboard shafts (4) drive the moldboards (3) to perform reciprocated swinging, and a driving device for driving the moldboard shafts (4) to perform reciprocated swinging is arranged outside the shell (1). By means of the boiler high-temperature bottom residue conveying device and the boiler high-temperature bottom residue energy recycling method, the using rate of the high-temperature bottom residue energy is high, the structure is simple, quick-wear parts are fewer, the reliability is high, the sealing performance is good, and the heat preservation effect is good; and the boiler high-temperature bottom residue conveying device and the boiler high-temperature bottom residue energy recycling method are suitable for wide popularization and application.

Description

technical field [0001] The invention relates to a boiler high-temperature bottom slag conveying device and a boiler high-temperature bottom slag energy recovery method, belonging to the technical field of transmission equipment manufacturing and energy reuse. Background technique [0002] The bottom slag conveying device of pulverized coal boiler is currently mainly wet scraper slag scraper and air-cooled dry slag discharger. The wet scraper scraper needs to consume a certain amount of water, the equipment structure is relatively complex, and the operation may cause problems such as water explosion and water leaching of slag; and the comprehensive utilization value of the bottom slag is low, and the chemical energy of the unburned carbon in the slag is not enough. Can be effectively used, the physical sensible heat in the bottom slag is wasted. The air-cooled dry slag discharger has poor adaptability to changes in boiler slag volume, complex equipment structure, high failur...
