Abstract
The utility model discloses a kind of device preventing accumulated ash into lump in cyclone dust collectors, it is characterized in that: comprise gas bag, cylinder, described gas bag one end connects high pressure nitrogen pipeline, and the other end connects fluidisation tuyere, and fluidisation tuyere is arranged on cyclone dust collectors bottom; By flange seal bottom cyclone dust collectors, flange one end is provided with rotating shaft, and flange is connected with cylinder, is rotated under cylinder action by rotating shaft.This device makes dust stratification fluidization in ash bucket, by the back-pressure of gases at high pressure, stops partially combusted furnace gas to enter cyclone dust collectors, reduces condensed water source, effectively prevents accumulated ash into lump.
Description
Technical field
The utility model relates to a kind of device preventing accumulated ash into lump in cyclone dust collectors, belongs to mechanical field.
Background technology
RH stove is when smelting, and need to carry out the techniques such as oxygen blast, decarburization, alloying and desulfurization, period can produce a large amount of dusts, and during dark desulfurization, dust is larger, and these dusts 95% are gathered in the ash bucket of cyclone dust collectors bottom.During non-smelting, top rifle toasts RH stove vacuum tank by using natural gas and oxygen combustion, the part furnace gas of high water vapor content can be condensed into droplet in air cooler, be gathered in the ash bucket of cyclone dust collectors bottom with gravity, As time goes on dust stratification and the condensation globule lump in ash bucket, to be difficult to when ash bucket lower flange puts ash release opening, impact is produced.
Summary of the invention
The utility model provides a kind of device preventing accumulated ash into lump in cyclone dust collectors, makes the dust stratification fluidization be deposited in ash bucket, effectively prevent caking.
The technical solution adopted in the utility model is: a kind of device preventing accumulated ash into lump in cyclone dust collectors, it is characterized in that: comprise gas bag, cylinder, described gas bag one end connects high pressure nitrogen pipeline, and the other end connects fluidisation tuyere, and fluidisation tuyere is arranged on cyclone dust collectors bottom; By flange seal bottom cyclone dust collectors, flange one end is provided with rotating shaft, and flange is connected with cylinder, is rotated under cylinder action by rotating shaft.
Liquid level gauge is provided with above described gas bag.
Described flange comprises upper flange and lower flange, is provided with O RunddichtringO between upper flange and lower flange.
The device of what the utility model provided prevent accumulated ash into lump in cyclone dust collectors, at the end of RH stove is smelted, after high pressure nitrogen enters gas bag voltage stabilizing and current stabilization, after fluidisation tuyere, nitrogen flows out at a high speed, make the dust stratification fluidization be deposited in ash bucket, bottom cyclone dust collectors, form fluidisation section, effectively prevent caking.During non-smelting, top rifle toasts RH stove vacuum tank by using natural gas and oxygen combustion, the part furnace gas of high water vapor content can be condensed into droplet in cyclone dust collectors, be gathered in the ash bucket of bottom with gravity, As time goes on dust stratification and condensed water can lump in ash bucket, if when toasting RH stove vacuum tank, open high pressure nitrogen, fluidisation section can be formed in ash bucket bottom, namely accumulated ash into lump is prevented, certain back-pressure can also be formed, effectively stop part furnace gas to enter cyclone dust collectors, decrease the source of condensed water.Can also detect condensed water by the liquid level gauge on gas bag, the science of accomplishing puts ash simultaneously.
The utility model is by installing the fluidisation tuyere that connects gases at high pressure in cyclone dust collectors bottom, make dust stratification fluidization in ash bucket, by the back-pressure of gases at high pressure, stop partially combusted furnace gas to enter cyclone dust collectors, reduce condensed water source, effectively prevent accumulated ash into lump.And detecting condensed water by the liquid level gauge on gas bag, the science of accomplishing puts ash, ensures production direct motion.
Below in conjunction with drawings and Examples, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is cyclone dust collectors, and 2 is gas bag, and 3 is cylinder, and 4 is high pressure nitrogen pipeline, and 5 is fluidisation tuyere, and 6 is liquid level gauge, and 7 is upper flange, and 8 is lower flange, and 9 is O RunddichtringO, and 10 is rotating shaft, and 11 is the globule, and A is dust direction, and B is fluidisation back-pressure direction.
Detailed description of the invention
Embodiment:
As shown in Figure 1, a kind of device preventing accumulated ash into lump in cyclone dust collectors, is characterized in that: comprise gas bag 2, cylinder 3, and described gas bag 2 one end connects high pressure nitrogen pipeline 4, and the other end connects fluidisation tuyere 5, and fluidisation tuyere 5 is arranged on cyclone dust collectors 1 bottom; By flange seal bottom cyclone dust collectors 1, flange one end is provided with rotating shaft 10, and flange is connected with cylinder 3, is rotated under cylinder 3 acts on by rotating shaft 10.
Liquid level gauge 6 is provided with above described gas bag 2.
Described flange comprises upper flange 7 and lower flange 8, is provided with O RunddichtringO 9 between upper flange 7 and lower flange 8.
Operation principle of the present utility model: by arranging the Laval fluidisation tuyere 5 connecting gases at high pressure bottom cyclone dust collectors 1, make dust stratification fluidization in ash bucket, forms fluidisation section in bottom, effectively prevent accumulated ash into lump; Simultaneously by gases at high pressure back-pressure upwards (in figure B direction), the globule 11 preventing the furnace gas of high water vapor content to be formed falls into bottom deduster, reduces condensed water source, effectively prevents accumulated ash into lump.Detect condensed water by liquid level gauge in running, the science of realization puts ash, ensures production direct motion.Putting grey process is the opening and closing being realized cyclone dust collectors by cylinder action on flange.
