Description
Technical field
The utility model relates to a kind of deashing device, particularly relates to a kind of honeycomb type denitrification catalyst deashing device.
Background technology
Honeycomb type denitrification catalyst during process, generally can be furnished with ultrasonic deashing device in SCR reactor, but along with the increase of running time and the unstability change of ature of coal, the situation that catalyst pores is blocked by dust can occur.Prior art is cleaning ash disposal regeneration after being taken out by catalyst module.CN202315706 U discloses a kind of ash removing device for regenerating flue gas denitrifying catalyst, brush holder support is utilized to rotate under the driving of motor, brush holder support is stretched into the tiny fly ash granule that honeycombed catalyst pore interior removes catalyst pores inside, but the hole that cannot realize there is dust blocking is dredged; Need catalyst to regenerate after SCR takes out, cost is high, and efficiency is low, consuming time.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of honeycomb type denitrification catalyst deashing device, its structure is simple, easy to operate, safety and environmental protection, efficiency are high, not only the hole that dust blocking occurs can be dredged, and hole can also be dredged in SCR reactor.
The utility model solves the technical scheme that its technical problem adopts:
Described honeycomb type denitrification catalyst deashing device, comprise high power vacuum cleaner, dust shield, hollow stainless pipe and fixed axis, high power vacuum cleaner is connected with dust shield by flexible pipe, hollow stainless pipe evenly through and be fixed on dust shield; Dust shield center line two ends are equipped with fixed axis, and fixed axis is parallel to hollow stainless pipe.
Described high power vacuum cleaner, can ensure the pressure adjustable of hollow stainless pipe pipe interior.
Described fixed axis is used for fixing deashing device, and prevent from rocking when deashing device runs, collision free is to honeycomb type denitrification catalyst.
The base of described dust shield is square.
The length of described hollow stainless pipe is 500mm-1300mm, and external diameter is 3mm-6mm, and the centre-to-centre spacing of pipe is 7-10mm, and the quantity of row's pipe is 14-22 root, and the tube wall bottom of pipe is cross-shaped aperture shape.When blocking occurs in catalyst duct, before deashing, the advantage of this shape can be utilized, with the dynamic dust saved bit by bit of hollow stainless pipe stamp, be beneficial to concentrated deashing process.
When honeycomb type denitrification catalyst duct piles with dust or is blocked by dust, first the hollow stainless pipe in honeycomb type denitrification catalyst deashing device is inserted in honeycomb type denitrification catalyst duct, then fix the fixed axis at two ends, start high power vacuum cleaner, carry out concentrated deashing.
The beneficial effect that the utility model has is:
The utility model structure is simple, easy to operate, safety and environmental protection, efficiency are high, not only can dredge the hole that dust blocking occurs, and can also dredge hole in SCR reactor.

Described high power vacuum cleaner 1, can ensure the pressure adjustable of hollow stainless pipe pipe interior.
Described fixed axis 4 is for fixing deashing device, and prevent from rocking when deashing device runs, collision free is to honeycomb type denitrification catalyst.
The base of described dust shield 2 is square.
The length of described hollow stainless pipe 3 is 500mm, and external diameter is 6mm, and the centre-to-centre spacing of pipe is 10mm, and the quantity of row's pipe is 14, and the tube wall bottom of pipe is cross-shaped aperture shape (as shown in Figure 2).When blocking occurs in catalyst duct, before deashing, the advantage of this shape can be utilized, stab the dynamic dust saved bit by bit with hollow stainless pipe 3, be beneficial to concentrated deashing process.
When honeycomb type denitrification catalyst duct piles with dust or is blocked by dust, first the hollow stainless pipe 3 in honeycomb type denitrification catalyst deashing device is inserted in honeycomb type denitrification catalyst duct, then fix the fixed axis 4 at two ends, start high power vacuum cleaner 1, carry out concentrated deashing.
Embodiment 2
As depicted in figs. 1 and 2, other identical all with embodiment 1, difference is:
The length of described hollow stainless pipe 3 is 1300mm, and external diameter is 3mm, and the centre-to-centre spacing of pipe is 7mm, and the quantity of row's pipe is 22.
