Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of solid powder Denitration in Boiler dedicated transport dress
It sets, including fixed link 1,1 both ends of fixed link are fixed on flue inner wall, and fixed link 1 is below denitrating catalyst, 1 bottom of fixed link
Face is connected with filter device 2, and filter device 2 is the fire-retardant filter cotton of high temperature resistance glass fiber.Fixed link is connected with first among 1 upper surface
Motor 3, and 3 output end of first motor is downward, the output end of first motor 3 is connected with bull stick 31, and bull stick 31 passes through fixed link 1
With filter device 2.One end side of the bull stick 31 under filter device 2 is connected with drive rod 4, and low water 41 is provided on the upside of drive rod 4.
