Abstract
The utility model discloses a kind of powder collection device of dry type deacidification system, including grinder, further includes pulverized-coal collector, intermediate warehouse and bag filter；The discharge port of the grinder and the feed inlet of pulverized-coal collector connect, and the material outlet of the pulverized-coal collector is connect with intermediate warehouse, and gas vent is connect with bag filter.The gas for being mingled with dust after the utility model grinds grinder is passed through in pulverized-coal collector, it may separate out 90% dust, the part dust discharging is kept in spare into intermediate warehouse, remaining dust, which is mixed in gas, to be discharged into fiber bag precipitator and further filters, and dust content is greatly lowered in the gas of filtered exclusion.
Description
Technical field
The utility model relates to a kind of dry-process deacidification systems, more particularly, to the powder after dry type deacidification system powder
Collection device.
Background technique
The technology that most dry-process deacidification systems use at this stage is dry to be used as using calcium oxide or calcium hydroxide (calcium hydroxide)
The reactant of method depickling.This acid stripping method reaction efficiency is relatively low, in order to guarantee deacidification efficiency, often will increase the reality of material
For border straying quatity to reach scheduled deacidification efficiency, this way often will increase the operating load of deduster after depickling reaction, right
The difficulty that exhaust gas dust discharges after control processing is opposite to be increased.And calcium hydroxide category strong alkaline substance, irritating and corrosiveness.
The dust of generation has intense irritation to respiratory tract, it is also possible to cause pneumonia, eye contact also has intense irritation, can cause to burn
Wound.
Summary of the invention
Goal of the invention: the utility model aim is in view of the deficiencies of the prior art, to provide a kind of dry type deacidification system
Powder collection device reduces exhaust gas dust discharge.
Technical solution: the powder collection device of dry type deacidification system described in the utility model, including grinder, in also wrapping
Include pulverized-coal collector, intermediate warehouse and bag filter；The discharge port of the grinder and the feed inlet of pulverized-coal collector connect,
The material outlet of the pulverized-coal collector is connect with intermediate warehouse, and gas vent is connect with bag filter.
Further preferably technical solution is the utility model, and the bottom of the bag filter is provided with discharge port, institute
Discharge port is stated to connect by tripper and the intermediate warehouse；Air outlet, the air outlet are provided at the top of bag filter
It is connect with centrifugal blower, the gas in the bag filter is discharged the centrifugal blower.
Preferably, the bag filter is connected by weight-loss type tripper and the intermediate warehouse.
Preferably, star-like unload is additionally provided on the connecting line between the weight-loss type tripper and the bag filter
Expect valve.
The utility model has the advantages that the gas for being mingled with dust after the utility model grinds grinder is passed through in pulverized-coal collector, it can
90% dust is isolated, which keeps in spare into intermediate warehouse, remaining dust, which is mixed in gas, to be discharged into
Fiber bag precipitator further filters, and dust content is greatly lowered in the gas of filtered exclusion, simultaneously as through meticulous
The separation of powder separator substantially reduces the operating load of bag filter, so as to reduce the filter area of bag filter,
Reduce investment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of powder collection device described in the utility model；
In figure, 1- grinder, 2- pulverized-coal collector, the centre 3- warehouse, 4- bag filter, 5- weight-loss type tripper, 6-
Centrifugal blower.
Specific embodiment
Technical solutions of the utility model are described in detail below by attached drawing, but the protection scope of the utility model
It is not limited to the embodiment.
Embodiment 1: a kind of powder collection device of dry type deacidification system, including grinder 1, further include pulverized-coal collector 2,
Intermediate warehouse 3 and bag filter 4；The discharge port of grinder 1 is connect with the feed inlet of pulverized-coal collector 2, pulverized-coal collector 2
Material outlet is connect with intermediate warehouse 3, and gas vent is connect with bag filter 4.
The bottom of bag filter 4 is provided with discharge port, and discharge port is connect by weight-loss type tripper 5 with intermediate warehouse 3,
Star-shaped discharge valve is additionally provided on connecting line between weight-loss type tripper 5 and bag filter 4；The top of bag filter 4
Portion is provided with air outlet, and air outlet is connect with centrifugal blower 6, and the gas in bag filter 4 is discharged centrifugal blower 6.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
