Hot precipitator used in journey.
Background technology
In dedusting technology field, double-layer filter material grain bed dedusting has unique technology advantage, and filtering is using thick, thin two kinds filters
Material is placed on the different filter bed Rotating fields of same filter element, and the coarse filtration bed of material is upper, and the fine filtering bed of material passes through filter bed mistake under
Filter, to reach good dust removal by filtration effect.In the prior art, filter element longitudinal arrangement makes height too high in deduster, reaches
More than 17 meters, and deduster is mostly used for high wind-force area, in these areas, often increases by 1 meter of height, required windproof base
Building requirement will be much higher, and the requirement for steelframe is also higher, therefore installs, protects cost very high.Moreover, existing deduster knot
Structure longitudinal arrangement, passage section is narrower, and blowback air wind speed on section is big, little particle powder of the disperse in deduster bottom after blowback
Dirt is difficult to be deposited to hopper bottom, and concentration can be larger, when normal filtration work starts after blowback, has more disperse in flue gas
Little particle dust be drawn back into filter element, especially for close to deduster bottom filter element, do not reach cleaning filter
The effect of the bed of material, dust stratification is more, and hindering operation, falling-rising is high, and effective filtration area is reduced, and influences final filter effect.
The content of the invention
It is an object of the invention to provide a kind of device total height is low, good filtration effect, blowback cleaning effect more preferably, can pole
It is big to avoid after reverse gas cleaning inside the dust suction filter bed of material again, high insulating effect and deduster that the upper and lower temperature difference is small, operation
Stable, safe hot precipitator.
In order to achieve the above object, the present invention is adopted the following technical scheme that：
Hot precipitator, including the shell in horizontal setting, several filter element groups in shell and it is arranged on shell

Compared with prior art, beneficial effect is the present invention：
Clever structure of the present invention, shell is set to horizontal, and cross section is big, in the case of flue gas flow identical, the horizontal stroke passed through
Section is bigger, then flow velocity is smaller, and flow velocity becomes hour dust settling without interruption, free settling to hopper bottom, is repeated to blow by air-flow
The influence risen is minimum, enhances cleaning efficiency, after blowback, just because of the cross section of shell is big, little particle dust is in outer casing bottom
Disperse area it is just wide, blowback air-flow is small in cross section wind speed, dust free settling, so that it may greatly reduce and return little particle dust again
It is drawn onto in filter material layer, it is ensured that the cleaning effect and stability of blowback；Meanwhile, the height of hot precipitator of the invention is more existing
The hot precipitator of the type in technology can be reduced substantially, or even drop to less than 10 meters, greatly reduce capital construction and install, dimension
Cost is protected, security is also greatly improved；In addition, the present invention needs the gas typically flammable explosive gas of dedusting, oxygen pole is met
Easily fire, therefore need equipment sealing very good, therefore, it is necessary to retain certain altitude during discharge dust, on the one hand material sealing, another
Aspect can reduce with the top temperature difference, beneficial to insulation, raising cleaning efficiency of the invention, which is set, can reduce dedusting operating pressure, easily
The speed of dust is discharged in management and control, enters with explosion-proof and insulation to protect the high temperature needed for separation that there is weight for sealing air-prevention
Meaning is wanted, therefore practicality of the present invention is extremely strong, with huge economic value, is worthy to be popularized.
