It can be used continuously in high temperature environments, has good thermal fatigue resistance and high temperature resistance, and is not easy to use repeatedly. There is no possibility of cross-collapse problem in case of thermal column phenomenon, which will create more favorable conditions for continuous production of enterprises. There is no longer any requirement for bricks and masonry, the operation steps are simplified, and the labor intensity is reduced. It is suitable for primary dust removal in dry coke quenching process.
Description
Technical field
The utility model relates to the coking field, especially a kind of disposable dust remover.
Background technology
Dry quenching system mainly partly is made up of dried stove, charging apparatus, coke discharging device, lift, disposable dust remover, secondary filter, coke dry quenching boiler system, recirculation blower, dedusting terrestrial station, water treatment system, automatic control system, the power generation system etc. put out.Wherein disposable dust remover utilizes gravity settling formula dust-cleaning principle that the macrobead coke powder in the recycle gas is separated, and reduces recycle gas to erosive wear, especially two stage superheater pipeline that generator tube produces, reaches the purpose of protection generator tube.
The disposable dust remover shell is welded by the taper ash bucket of end face, side, both sides, two ends end face, bottom, and constitutes airtight cavity by end face, side, both sides, two ends end face, ash bucket encirclement, and enclosure is built heat insulation wall by laying bricks or stones.Disposable dust remover inlet, outlet are arranged at the two ends end face respectively and respectively by high temperature expansion joint and the dried pipe connection that puts out stove, boiler.The dedusting barricade is built by laying bricks or stones with wearing-proof refractory material and is formed, be arranged at inlet the place ahead and vertical with air flow line, top is connected with the end face insulated wall, the side is connected with the both sides insulated wall, the bottom is connected with the insulated wall on ash bucket surface, by the dedusting barricade cavity is divided into two portions, and dedusting barricade bottom is provided with connection cavity two portions, holds the arch opening that gas passes through.
After the recycle gas that contains coke powder enters fly-ash separator, stopped that by the dedusting barricade gas alters course after the opening of dedusting barricade bottom enters opposite side, and finally enters outlet; And coke powder falls after touching the dedusting baffle plate, and is collected by ash bucket, thereby realizes dust separating purpose.The impact of dedusting barricade own wt and high speed recycle gas is being connected by arch opening both sides and ash bucket insulated wall all, carry with the connection of corresponding insulated wall two sides, therefore to the specification of quality of building materials with to build requirement by laying bricks or stones all very high, especially along with the maximization of industrial coke oven and supporting dry coke quenching, the dedusting barricade is also increased thereupon and is widened, thereby to the specification of quality of building materials with to build requirement by laying bricks or stones strict more, when a certain link has problem slightly, being easy to cause barricade to stride in process of production collapses, cause dried put out stove and boiler systems production interruption, have to total system is carried out decrease temperature and pressure, satisfy the requirements afterwards barricade to be striden to collapse and remove and organize manpower, material resources are built by laying bricks or stones again, and enterprise is caused heavy losses.
The utility model content
Technical problem to be solved in the utility model provides a kind of disposable dust remover that can avoid the dedusting barricade to collapse.
The technical scheme that its technical problem that solves the utility model adopts is: disposable dust remover, comprise shell, dedusting barricade, and described shell comprises end face, side, both sides, two ends end face, described dedusting barricade is a steel construction.
Described dedusting barricade comprises framework and is covered in one group of steel plate on framework surface, passes through bolting between described steel plate and the framework.
Described outer casing top surface is provided with the lifting groove of dedusting barricade, the sealing cover of lifting groove; Described lifting groove both sides are respectively arranged with and hang the fixedly fixed beam of dedusting barricade, and described dedusting barricade top is connected by latch or bolt with fixed beam.
Described shell both sides are respectively arranged with guide path on the side.
The beneficial effects of the utility model are: steel construction has high temperature resistant, corrosion-resistant, wear-resistant, anti-oxidant, anti-high stream, shock resistance, welding characteristic, under hot environment, can use continuously, have good thermal fatigue resistance and resistance to elevated temperatures, use repeatedly and be difficult for producing hot row phenomenon, can not exist and stride the problem of collapsing, enterprise's continuous production is created favourable condition more.No longer to brick with built requirement by laying bricks or stones, the step that simplifies the operation reduces labour intensity.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is the front view of the utility model dedusting barricade.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, disposable dust remover of the present utility model comprises shell 1, dedusting barricade 2, and described shell 1 comprises end face 3, side, both sides, two ends end face, and described dedusting barricade 2 is steel construction.
That steel construction has is high temperature resistant, corrosion-resistant, wear-resistant, anti-oxidant, anti-high stream, shock resistance, welding characteristic, under hot environment, can use continuously, have good thermal fatigue resistance and resistance to elevated temperatures, use repeatedly and be difficult for producing hot row phenomenon, can not exist and stride the problem of collapsing, enterprise's continuous production is created favourable condition more.No longer to brick with built requirement by laying bricks or stones, the step that simplifies the operation reduces labour intensity.
Steel construction can directly be fixedlyed connected with shell 1 by welding, when the 1 local appearance of dedusting barricade is damaged, repairs by the mode of cutting, welding.But the aforesaid way troublesome poeration, for convenience to the 2 partial maintenances of dedusting barricade, further, described dedusting barricade 2 comprises framework 21 and is covered in one group of steel plate 22 on framework 21 surfaces, passes through bolting between described steel plate 22 and the framework 21.When certain steel plate 22 needs to change, only need this steel plate 22 of dismounting and change to get final product.
Further, for convenience of the integral replacing of dedusting barricade 2, described shell 1 end face 3 is provided with the lifting groove 4 of dedusting barricade 2, the sealing cover 5 of lifting groove 4, and described dedusting barricade 2 is fixing by detachably fixedlying connected with shell 1.In addition, also shell 1 end face 3 all can be set to detachable structure with side, both sides, two ends end face, but operation is loaded down with trivial details when changing.
Dedusting barricade 2 can be fixed by side, both sides or side, both sides and bottom ash bucket etc.But in order further to simplify the operation, described lifting groove 4 both sides are respectively arranged with and hang the fixedly fixed beam 6 of dedusting barricade 2, and described dedusting barricade 2 tops and fixed beam 6 are connected by latch.Except that latch, also can fix by bolt.
Because dedusting barricade 2 adopts to hang and fixes, in order to guarantee the stability of its position under gas shock, guarantee the resistance to air loss of dedusting barricade 2 both sides, described shell 1 both sides are respectively arranged with guide path 7 on the side.Guide path 7 the installation that can also make things convenient for simultaneously dedusting barricade 2 is set.
