Boiler dry deslagging system

Abstract

The invention discloses a boiler dry deslagging system. The boiler dry deslagging system comprises a first conveying mechanism, a storage bin with a feeding port and a discharging port, a humidifying and cooling mechanism and a second conveying mechanism, the first conveying mechanism comprises a first conveying belt located at the bottoms of boilers, and the first conveying belt is used for conveying ash discharged by the boilers to the feeding port of the storage bin. The humidifying and cooling mechanism comprises a humidifying chamber and a cooling medium supply part used for conveying a cooling medium into the humidifying chamber, the humidifying chamber is provided with a slag inlet and a slag outlet, and the slag inlet of the humidifying chamber communicates with the discharging port of the storage bin. The second conveying mechanism comprises a second conveying belt located in the humidifying chamber, and the second conveying belt is used for conveying the ash humidified by the cooling medium to the slag outlet of the humidifying chamber. According to the boiler dry deslagging system, dry ash is humidified while being cooled, ash impurities are conveyed to the outside in a humid state, the ash is prevented from being raised, and a good operation environment of equipment is guaranteed. The dust falling effect is good, the machining efficiency is high and safety is achieved.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a boiler dry slag removal system. Background technique [0002] Boiler dry slag removal system is a major subsidiary system of a thermal power plant. At present, the slag in the boiler is mainly transported to the slag bin in the form of a slag cooler + conveyor, and then the slag in the slag bin is transported through the pipeline at the bottom of the slag bin. The slag is shipped to the loading truck for transport away. Due to the height difference between the pipeline at the bottom of the slag bin and the loading vehicle, it is very easy to generate dust when the slag is put into the loading vehicle, resulting in a poor site environment, which is harmful to the health of the staff; the existing construction In order to prevent the dust from spreading, the method of spraying water is usually used for dust reduction. However, the dust reduction effect of this method is poor and it is dif...

Due to the height difference between the pipeline at the bottom of the slag bin and the loading vehicle, it is very easy to generate dust when the slag is put into the loading vehicle, resulting in a poor site environment, which is harmful to the health of the staff; the existing construction In order to prevent the dust from spreading, the method of spraying water is usually used for dust reduction. However, the dust reduction effect of this method is poor and it is difficult to ensure the stable diffusion position of the water mist in windy weather, which is not conducive to the safe discharge of ash.
