Abstract
The utility model provides a dust remover barricade of dry quenching device, including a plurality of arches commentaries on classics piece layer range upon range of from top to bottom, through the tongue and groove interlock between the adjacent arch fragment of brick layer, the domes piled up side by side for a plurality of fragments of brick of arch fragment of brick layer, through the tongue and groove interlock between the adjacent fragment of brick. Every arch is changeed and is left the 6 -10mm clearance between piece layer and the adjacent arch fragment of brick layer, and the packing has the alumina silicate fibre blanket in the clearance. The utility model discloses a domes and occlusal structure improve the ability of resisting hot -blast impact, also can eliminate the hidden danger of work progress.
Description
Technical field
The utility model relates to dust removal installation field, specifically a kind of dry coke quenching auxiliary disposable dust remover barricade.
Background technology
Coal, after coking chamber is smelt coke, should be released from coking chamber in time, and when red Jiao releases, temperature is about 1000 DEG C.Burn for avoiding coke and be suitable for transport and storage, directly can not be sent to blast furnace ironmaking, red burnt temperature must be reduced.A kind of coke quenching method adopts water spray red burnt temperature to be reduced to 300 ° of below C, namely usually said coke wet quenching.Conventional wet quench system is made up of the coke quenching tower with spray water system, quenching pump house, coke quenching water settling tank and all kinds of pipe arrangement, and the steam that quenching produces directly is discharged in air.
Dry coke quenching technique originates from Switzerland, and many developed countries began one's study and developed dry coke quenching Technology the forties in 20th century.In dry coke quenching technological process, red Jiao loads from dry furnace roof portion of putting out, cryogenic inert gas is blasted by recirculation blower and dryly puts out in the red focus layer of stove cooling section, absorb red burnt sensible heat, cooled coke is discharged from the dry furnace bottom that puts out, and flows through dry coke quenching process boilers carry out heat exchange, boiler develops steam vapor from dry annular flue high temperature inert gas out of putting out, cooled rare gas element is again blasted by recirculation blower and dryly puts out stove, and rare gas element uses at the system internal recycle closed.Dry coke quenching technique is in energy-saving and environmental protection and improve in coke quality etc. and be better than coke wet quenching.
In dry coke quenching technique, recycle gas needs to carry out dust suppression, usually realizes by increasing fly-ash separator barricade.Existing fly-ash separator barricade as depicted in figs. 1 and 2, first forms long strip shape fragment of brick group by horizontal stack block of laying bricks, then form barricade by some long strip shape fragment of brick group stacked on top of one another, use partial dome structure increase structural stress in barricade.Prior art has following shortcoming:
1, because the hot blast of high speed and high pressure impacts larger, the stress self produced is piled up larger between large-scale fragment of brick, fly-ash separator barricade can only use brick less than normal, single brick weight is at about 3kg, maximum brick list brick weight is about 22kg, but is also only used to the supporting role playing simple reinforcing and bottom.
2, switch block builds gap by laying bricks or stones comparatively greatly, easily comes off.
3, single brick quantity is more, and mortar joint is more, easily has uneven hidden danger to exist during construction, affects fly-ash separator barricade impact resistance.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of dry coke quenching auxiliary disposable dust remover barricade, is improved the ability of opposing hot blast impact, also can eliminate the hidden danger of construction process by domes and occlusion structure.
The utility model comprises some arch switch block layers of stacked on top of one another, is engaged between adjacent arch block layer by tongue and groove; Described arch block layer is the domes that some fragments of brick are piled into side by side, is engaged between adjacent fragment of brick by tongue and groove.Occlusion between every block list brick is to make whole single arch form an entirety, and the occlusion between every stringcourse is to make several single arch form an entirety.
The utility model can use larger brick, and whole face wall body overarches combination, utilizes self stress of arch, and more effective opposing hot blast impacts, and also can eliminate the hidden danger of construction process.And increase inner occlusion structure, make whole face wall body form an entirety, the ability that the hot blast further increasing opposing high speed and high pressure impacts.
Further improvement, leaves 6-10mm gap between each arch switch block layer and adjacent arch block layer, is filled with alumina silicate fibre blanket in gap.Described alumina silicate fibre blanket thickness is at least 16mm, inserts the gap between arch block layer after compression.The gap of reserved fragment of brick thermal expansion, prevents fragment of brick from expanding with heat and contract with cold and causes barricade to damage.
Accompanying drawing explanation
Fig. 1 is existing fly-ash separator barrier wall structure schematic diagram.
Fig. 2 is close-up schematic view in Fig. 1.
The fly-ash separator barricade front view that Fig. 3 provides for the utility model.
The fly-ash separator barricade left view that Fig. 4 provides for the utility model.
The fly-ash separator barricade vertical view that Fig. 5 provides for the utility model.
Embodiment
As shown in Figure 3, be several layers of (according to the physical size of various dry coke quenching auxiliary different and different) arch block layer composition, bed rearrangement barricade does not exist without dependence connectionless single brick the utility model one-piece construction.Every stringcourse shape block layer is made up of 48 ~ 96 pieces of single bricks, is mutually engaged, mutual tractive between every block list brick and every stringcourse, effectively to resist the impact of the high velocity air carrying coke powder particle secretly, and the thermal stresses that temperature variation is brought.
Occlusion (as shown in Figure 5) between every block list brick is to make whole single arch form an entirety, and the occlusion (as shown in Figure 4) between every stringcourse is to make several single arch form an entirety.
Why be designed to several arch composition barricade, because arch has the power naturally drooped, and mutual jam-packed, thus more firm.
Leave 6-10mm gap between each arch switch block layer and adjacent arch block layer, in gap, be filled with alumina silicate fibre blanket.Described alumina silicate fibre blanket thickness is at least 16mm, inserts the gap between arch block layer after compression.The gap of reserved fragment of brick thermal expansion, prevents fragment of brick from expanding with heat and contract with cold and causes barricade to damage.
The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
Claims (3)
1. a dry coke quenching auxiliary disposable dust remover barricade, is characterized in that: the some arch switch block layers comprising stacked on top of one another, are engaged by tongue and groove between adjacent arch block layer; Described arch block layer is the domes that some fragments of brick are piled into side by side, is engaged between adjacent fragment of brick by tongue and groove.
2. dry coke quenching auxiliary disposable dust remover barricade according to claim 1, is characterized in that: leave 6-10mm gap between each arch switch block layer and adjacent arch block layer, be filled with alumina silicate fibre blanket in gap.
