Description
Technical field
The utility model is related to the technical fields of blast cap, more particularly to the technical field of hood of fluidized bed furnace.
Background technology
Fluidized bed furnace is a kind of burning boiler, relatively broad in sector applications such as cement, power plant, ore dressings, and blast cap is fluidized bed furnace
Upper very important component, its underpart is fixed on air distribution plate blast cap when in use, and fire-proof mud is used in combination to carry out pouring covering, is exposed
Blast cap head is used for cloth wind, and pressure-air is blown into fluidized bed furnace from the micropore of blast cap head, blows fuel particle, make air and fuel
Grain mixing makes fuel particle form fluidized state and burns.And blast cap common at present has the following deficiencies：When by
In working under high temperature environment, and pass through washing away and wearing for high-speed flow and clinker, blast cap head easily damages, wherein heat resistance
Difference, oxidation deformation are the principal modes of blast cap head failure, it is therefore desirable to often be replaced to blast cap.And blast cap common at present
Mostly monoblock type blast cap, when needing to replace blast cap, it is necessary to blast cap integrally be replaced, replaced blast cap is only
It can carry out scrapping processing, and the part of blast cap damage is only blast cap head, and the raw material of blast cap are generally expensive Gao Ge
Cast iron, the quantity that each blast cap is replaced is big, therefore causes great waste, has aggravated the production cost of enterprise；Replacing wind
It needs to batter down fire-proof mud when cap, operate cumbersome, it is time-consuming and laborious, and cause great waste.Second is that at present
Micropore on common blast cap is mostly horizontally disposed straight hole, and pressure-air blows range after micropore blowout to fuel bed
Limited, cloth wind effect is not very ideal, fuel bed cannot be made fully to float, and the fluid effect of fuel particle is poor, is unfavorable for
The burning of fuel, fuel economy are relatively low.
Utility model content
The purpose of this utility model be exactly provided to solve above-mentioned deficiency it is a kind of use split structure, be not necessarily to pair
Blast cap is integrally replaced, and production cost can be substantially reduced, and reduces waste, cloth wind effect is good, and fuel fluid effect can be improved, carry
The novel hood of fluidized bed furnace of high burning efficiency.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
A kind of novel hood of fluidized bed furnace, it is mainly made of blast cap head and connecting tube, and interior spiral shell is provided on the blast cap head
Line is provided with external screw thread in the connecting tube, and blast cap head is located on by its internal thread on the external screw thread of connecting tube, in blast cap head
With air inlet hole is offered in connecting tube, offer the exhaust vent being connected with the air inlet hole on the side wall of the blast cap head.
The upper end of the blast cap head is in mushroom-shaped, bell shape or umbrella shape.
The bottom of the connecting tube is provided with annular snap-gauge.
Exhaust vent on the blast cap rostral wall is made of upper air-out groove, spiral exhaust vent and lower exhaust vent, outlet air on this
Slot, spiral exhaust vent and lower exhaust vent are from top to bottom arranged successively, and respectively respectively in circumferentially, the upper air-out groove is along tiltedly
It tilts upward, in the shape of a spiral, the lower exhaust vent tilts the spiral exhaust vent along obliquely downward.
Air inlet hole on the blast cap head and connecting tube is taper.
The blast cap head is rich chromium cast iron material, and the connecting tube is cast iron quality.
The utility model is using the attainable advantageous effect of above-mentioned technical solution institute：By the blast cap of traditional monoblock type
It is divided into blast cap head and connecting tube two parts, and is attached fixation by the way of being threadedly coupled, when replacement need to only backs out blast cap
Head is replaced, and is integrally replaced without to blast cap, and need not be battered down fire-proof mud and be taken out connecting tube, meanwhile, connecting tube
Using the more cheap cast iron quality of price, production and application cost is thus greatly reduced so that replacement operation becomes very square
Just.Air inlet hole is arranged tapered so that gradually accelerate into the high pressure draught flow velocity in air inlet hole, to improve from outlet air
The flow velocity of the air-flow of hole blowout, improves and blows effect to the fluidized bed furnace internal combustion bed of material；Upper air-out groove is the channel-shaped of oblique top,
So that the air-flow of blowout is the planar in oblique top, to increase the area for blowing fuel bed, spiral exhaust vent is helically
Shape so that twist, cloth wind effect can be improved in the air-flow of blowout, and lower exhaust vent is tilted along obliquely downward, make the air-flow of blowout to
Oblique lower section blowout, makes the range that the air-flow blown out from blast cap head is blown by upper air-out groove, spiral exhaust vent and lower exhaust vent
Bigger, improves cloth wind effect, is fully blown to fuel bed, so that fuel bed is fully floated, effectively increase fuel combustion
Efficiency.
