Embodiment Construction

[0020] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0021] Such as figure 1 As shown, a boiler rapid bed material addition system is characterized in that it includes a slag bin 1, a screening mechanism 2, and a lifting mechanism 3; the slag bin 1 is connected to the screening mechanism 2 through a first pipeline 5; the screening mechanism 2 passes through The second pipeline 6 is connected with the lifting mechanism 3; the lifting mechanism 3 transports the coal slag to the boiler 4 through the material guide device 7.

[0022] The upper part of the slag bin 1 is a cylindrical section 11, and the lower part is a conical section 12. A bed material outlet is provided at the middle and lower part of the conical section 12; the outlet is connected to the first pipeline 5, and a gate valv...

Abstract

The invention discloses a system for quickly adding bed material to a boiler, which includes a slag bin, a screening mechanism, and a lifting mechanism; the slag bin is connected to the screening mechanism through a first pipeline; the screening mechanism is connected to the screening mechanism through a second pipeline The lifting mechanism is connected; the lifting mechanism transports the coal slag to the boiler through the material guide device. The included angles between the first pipeline and the second pipeline and the horizontal direction are both 70°-80°. Compared with the existing technology, the bucket lift type rapid bed material feeding system adopts the lifting method to transport the bed material, which saves the use of compressed air, and the conveying force is small to reduce wear, and the feeding speed of this system is fast, and the general time is 4‑5 Hours, the equipment has good stability, which provides a guarantee for the maintenance of the boiler and the departure of the unit.

Description

technical field [0001] The invention relates to the technical field of fluidized bed boilers, in particular to a system for quickly adding bed material to a boiler. Background technique [0002] The traditional fluidized bed boiler feeding system usually uses a set of pneumatic conveying device, which takes up to 48 hours each time to feed the bed material, which increases the start-up time of the unit, increases the maintenance items and construction period, and has a large production pressure. Pneumatic conveying equipment has poor operation stability and requires a large maintenance workload. Contents of the invention [0003] The object of the present invention is to solve the defects of long time consumption, many maintenance items and high energy consumption of the pneumatic bed material adding system in the prior art, and provide a boiler rapid bed material adding system to solve the above problems. [0004] The present invention realizes above-mentioned technical ...
