Abstract

The utility model relates to a high-temperature dry dust-removing device for a sintered wire filter screen. The utility model comprises at least two dust-removing filtering box bodies 4. Each dust-removing filtering box body 4 is provided with an air inlet pipe 1 and an air outlet pipe 6. A filter element 5 is a round pipe or a petal-shaped filter core made up of a sintered metal filter screen. A pipeline of the air outlet pipe 6 is provided with an inverse blow pipe 10. Compared with a bag dust remover, the utility model has the advantages of good mechanical property, corrosion prevention, little resistance and high filtering efficiency, and also has the advantages that the utility model can resist the high temperature of 700 DEG C; the filtering wind velocity can raise 10 times; the life time can reach more than five years; the occupation area is reduced; the volume is one fifth of a bag dust remover; metal structural parts are saved; the total investment can save one third; energy is thoroughly used.

Description

Sintering metal wire gauze filter high-temperature dry dust arrester
The utility model relates to a kind of dedusting filter, is applicable to the purification of blast furnace gas, also is applicable to converter, electric furnace, the hot stove in ore deposit and other high temperature dust gas cleaning.
At present, blast furnace gas purification dust collection method commonly used both at home and abroad has two kinds of dry method and wet methods, and the wet dedusting electric consumption is big, and water is seriously polluted, and occupation of land is many, needs to replenish a large amount of new water.The dry-method bag-type dust collecting device adopts cotton, nylon, glass fibre or synthetic fibers braiding to form, and it is low that heatproof is lower than 300 ℃, mechanical strength, cracky and burning, and filtration velocity is 0.5~1.0 meter/minute, the life-span lacks, maintenance difficult, the volume that takies is very big.And electrostatic precipitator power consumption, investment are big.Therefore, people consider to adopt novel filter material to make filter, for example Chinese patent application CN1144848A discloses a kind of " blast furnace gas fully-dried type dust arrester and dust collection method ", its key is that the filter core of deduster is to adopt the sintered metal mesh porous material, but this application is not introduced the concrete structure of deduster.
The purpose of this utility model is to obtain a kind of sintering metal wire gauze filter high-temperature dry dust arrester, and it is simple in structure, and volume is little, and is easily manufactured.
For achieving the above object, the technical solution that the utility model proposes is:
A kind of sintering metal wire gauze filter high-temperature dry dust arrester, it comprises: at least two dust removal and filtration casings 4, each dust removal and filtration casing 4 has air inlet pipe 1 and blast pipe 6, its filter element 5 is the sintering metal wire gauze filter, described filter element 5 is fixed on casing 4 by fixed head 13,14, and filter element 5 cross sections are circle or circular arc.
Filter element 5 is along the equally distributed pipe of circumference.
The cross section of filter element 5 is a polygon, and this polygonal limit is inside recessed circular arc.
Described polygon limit number is 3~8.
Filter element 5 is installed in the circular support 12, and the arc radius of the radius of support 12 and filter element 5 is close.
Pulley 11 is arranged at filter element 5 bottoms.
The coal gas heat riser is arranged before the gas entry valve 2.
Anti-blowpipe 10 is arranged on the blast pipe 6.
Fig. 1 is the structural representation of the utility model sintering metal wire gauze filter high-temperature dry dust arrester embodiment one.
Fig. 2 is an A-A cutaway view among Fig. 1.
Fig. 3 is the structural representation of the utility model sintering metal wire gauze filter high-temperature dry dust arrester embodiment two.
Fig. 4 is the a-a cutaway view among Fig. 3.
Below in conjunction with Figure of description the utility model is done and to be described in further detail:
Key of the present utility model is that the core pipe, the circular arc central layer that adopt sintered metal mesh to make are filter element, this element is installed in the casing 4 that general steel plate or alloy-steel plate make, this device comprises at least two casings, adopts a row formula or double block form, and each casing can take turns to operate.Referring to Fig. 1~4, the blast furnace raw coke oven gas is drawn the filter box that enters this deduster by air inlet pipe 1 from gravitational precipitator, and 2 is the gas entry butterfly valve, and 3 is glasses valve.Blast furnace gas can be lowered the temperature and directly be entered deduster, when the raw coke oven gas temperature is lower than dew point, establishes heater before gas entry butterfly valve 2, the raw coke oven gas temperature can be improved to enter dust arrester again.Glasses valve 8, butterfly valve 7 are arranged on the purified gas blast pipe 6, and it is deashing blowback butterfly valve that anti-blowpipe 10,9 is arranged on the pipeline of blast pipe 6.During use,, can carry out reverse gas cleaning or pulse dust cleaning and make it regeneration, devote oneself to work again when a casing quits work.
Introduce two embodiment of the present utility model below respectively.
Embodiment one
Referring to Fig. 1,2, the filter element of this embodiment is the tubular type filter core, and its cross section is circular, and this chimney filter is that sintered metal mesh is made, and arranges in each casing to be evenly distributed on 4 (or more than 4) in the round box along circumference.
Embodiment two
Referring to Fig. 3,4, one cylindrical stent 12 is arranged in this round box, cross section is that petal filter element 5 is installed in the support 12, the cross section of filter element 5 is the hexagon filter plate, this filter plate is inside recessed circular arc, and the radius of its arc radius and support 12 is close, and this structure is in the area maximum of same working volume inner filtration net, shock-resistant ability is higher, and processing technology is simple.Pulley 11 is arranged at filter element 5 bottoms, is convenient to move and maintenance.
Compare the sintering metal that the utility model obtains with fiber bag precipitator in the prior art Wire gauze filter high-temperature dry dust arrester can high temperature resistantly reach 700 ℃, and filtration velocity improves 10 Doubly, good mechanical property, anticorrosion, resistance is little, filter efficiency is high, the life-span as long as five years, body Long-pending 1/5 of the sack cleaner that is about, and save hardware, reduce floor space, the total throwing Money can save 1/3, and takes full advantage of the energy. High temperature purification coal gas direct heating through dedusting Wind furnace can improve hot blast temperature, strengthens the Coal powder spray amount, reduces coke ratio, increases output, falls Low cost increases economic benefit.
