Description
Technical field
The utility model relates to a kind of blast furnace gas gravitational dust collection ash discharge valve combination unit, relates to the tandem compound device of three valves specifically.
Background technique
Gravitational precipitator dust-cleaning principle reduces suddenly air-flow velocity and change to flow to, and the dust of larger particles, under gravity and inertial force effect, is separated with gas, is deposited to deduster cone bottom part, belongs to thick dedusting.
Gravitational precipitator is the gravitational settling by means of dust, the equipment separated from gas by dust.Dust is that flue gas enters gravitational settling equipment from substantially horizontal by the process of gravitational settling, and under gravity, powder dust particle settles down gradually, and gas moves in the horizontal direction, thus reaches the object of dedusting.Ash-discharging device is established in gravitational precipitator bottom.By ash-discharging device realize to dedusting ash in dust collector ash hopper draw off and carry.
Summary of the invention
The purpose of this utility model provides a kind of blast furnace gas gravitational dust collection ash discharge valve combination unit for the bottom ash-discharging device of gravitational precipitator.
The purpose of this utility model realizes by following technique measures:
The utility model blast furnace gas gravitational dust collection ash discharge valve combination unit comprises the adjustment type eccentric half-ball valve for regulating gravitational dust collection ash content flow, ash content for turning off blast furnace gas gravitational dust collection ash content closes eccentric half-ball valve, for the gas seal all-ball valve turned off blast furnace gas sealing, described adjustment type eccentric half-ball valve, ash content closes eccentric half-ball valve and gas sealing all-ball valve from top to bottom links together in the mode of series connection, and described adjustment type eccentric half-ball valve, ash content closes the valve shaft of eccentric half-ball valve and gas sealing all-ball valve respectively by sliding cross coupling, transmission shaft and rocking arm are connected to rack-mount corresponding driving oil cylinder.
Described adjustment type eccentric half-ball valve, ash content close eccentric half-ball valve and gas sealing all-ball valve does 0 ~ 90 respectively by the corresponding oil cylinder that drives
0rotate.Can realize to blast furnace gas gravitational dust collection ash bucket unload grey controlling functions and guarantee in off position time to the closedown of ash content and the reliable sealing of blast furnace gas.
Working principle of the present utility model is as follows:
Blast furnace gas gravitational dust collection ash discharge valve combination unit of the present utility model close time each valve state as follows: adjustment type eccentric semi-spherical valve core vertically upward, in closed position; Ash content closes eccentric half-ball valve valve core vertically upward, in closed position; Gas seal all-ball valve, spool in closed position, to complete shutoff to furnace gas and ash content in the ash bucket of top and sealing.
The state of blast furnace gas gravitational dust collection ash discharge valve combination unit of the present utility model each valve when unloading ash is as follows: adjustment type eccentric half-ball valve drives rocking arm, transmission shaft to drive spool to be rotated counterclockwise several angle α by driving oil cylinder, in position stop, unloading grey flow to regulate; Ash content is closed eccentric half-ball valve and is driven rocking arm, transmission shaft to drive spool to be rotated counterclockwise 90 by driving oil cylinder
0, stop at fully open position, now valve is opened completely; Gas seal all-ball valve, drives rocking arm, transmission shaft to drive spool to be rotated counterclockwise 90 by driving oil cylinder
0, stop at fully open position, valve is at fully open position, and three series connected valves form direct current channels, completes to unload ash to ash content in the ash bucket of top.
The beneficial effects of the utility model are as follows:
The utility model is by realizing the control to unloading grey flow easily to the control (Spool rotating angle [alpha]) of adjustment type eccentric half-ball valve aperture, the combination that ash content closes eccentric half-ball valve and all-ball valve is closed, and can guarantee the sealing of reliable turn-off to ash content and blast furnace gas.
