Description
Technical field
The present invention relates to flue gas of refuse burning depickling processing technology fields, are specially that deacidifying flue gas is filtered with lime slurry
Device.
Background technology
The fume desulphurization method mainly used after waste incineration at present is to use lime（Ca(OH)2）Slurries absorb rubbish
Acid ingredient after burning in flue gas, and the lime slurry configured is needed after filtering, the rotation mist in ability supply response tower
Change device to use.
Existing filter is as shown in Figure 1 when filtering lime slurry, since lime slurry has a little viscosity, in filter
It is easily attached on the opening of sieve of filter basket 2 in cylinder 1, so as to intercept the calcium hydroxide particle in slurries, causes stagnating for lime slurry,
And mesh is blocked, and it resulting in the need for frequently clearing up strainer, the personnel that need to configure specially are safeguarded, cause the waste of human cost,
Can also make when serious flue gas can not normal desulfurization, cause the discharge of flue gas can not be up to standard.
The content of the invention
Lime slurry is be easy to cause for existing filter to stagnate, block the shortcomings that mesh, the present invention provides flue gases to take off
Acid lime slurry filter, can be effectively improved the viscous problem of lime slurry, and then the time that mesh is delayed to block significantly,
It saves human cost and ensures being smoothed out for production.
The present invention adopts the following technical scheme that：Deacidifying flue gas lime slurry filter, it is described including cylinder and filter basket
Filter basket is sleeved in the cylinder, and cylinder upper end both sides are provided with lime slurry entrance and lime slurry outlet, described
The basket wall for filtering basket covers the lime slurry outlet, which is characterized in that it further includes agitating device, and the agitating device includes stirring
Axis and agitating paddle are mixed, the stirring slurry is stretched into the filter basket.
It is further characterized by：
The filter basket opened upper end, open ports are tilt port, and the low side of the tilt port is less than the lime slurry entrance, institute
The high-end of tilt port is stated to export higher than the lime slurry；
Two layers totally of the agitating paddle；Described two layers of agitating paddle is sleeved on the agitating shaft, respectively in the filter basket
Portion and bottom；
The end contact filter basket inner wall of the agitating paddle；
The agitating shaft and the cylinder, filter the center of basket on the same axis and with the center of the lime slurry entrance
Axis is mutually perpendicular to；
The capping of the agitating shaft through the cylinder is connected by gear with transmission system；
The transmission system includes speed reducer and motor.
With the above structure, centre is provided with agitating device to the present invention in the filter, therefore during filtering lime slurry, stirs
The disturbance of lime slurry can be increased by mixing paddle rotation, so as to reduce dead time of the lime slurry of viscosity in mesh, effectively be changed
The problem of kind lime slurry stagnates, and then the time that mesh is delayed to block significantly, save human cost and ensure production smoothly into
Row；And the end contact filter basket inner wall of agitating paddle, the slurries being adhered on filter basket can be wiped off, further ensure that and prolong
The time of slow mesh obstruction and being smoothed out for production.
Description of the drawings
Fig. 1 is the structure diagram of the prior art.
Fig. 2 is the structure diagram of the present invention.
Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in Fig. 2, the present invention provides deacidifying flue gas lime slurry filter, including cylinder 1 and filter basket 2, filter basket 2 is sleeved on
In cylinder 1,1 upper end both sides of cylinder are provided with lime slurry entrance 4 and lime slurry outlet 8, smooth in order to flow, can be by stone
Grey injection point 4 and lime slurry outlet 8 are arranged symmetrically；The basket wall covering lime slurry outlet 2 of basket 2 is filtered, and lime slurry enters
Mouthfuls 4 do not cover so that it is convenient to lime slurry enters filter basket 2, and while ensuring filter basket 2 is filtered；Filter basket 2 can also be used
Opened upper end mode, open ports are tilt port, and the low side of tilt port is high-end less than lime slurry entrance 4 to be higher than lime slurry
Outlet 8（Shown in Fig. 2）；It further includes agitating device, and the agitating shaft 7 of agitating device and cylinder 1 filter the center of basket 2 same
It is mutually perpendicular on one axis and with the central axis of lime white entrance 4, the agitating paddle 3 of agitating device divides two layers up and down, is set with
On agitating shaft 7, it is located at the middle part and bottom of filter basket 2 respectively；The inner wall of the end contact filter basket 2 of agitating paddle 3；Agitating shaft 7
The capping of top through cylinder 1 is connected by gear with speed reducer 5 and motor 6.
When being filtered to lime slurry, start stirring motor, stirring motor drives through speed reducer is located at filter cartridge
The agitating shaft in body center is rotated with 5 ~ 10 turns per minute of rate, and the agitating paddle being set on agitating shaft is i.e. by rotating increase stone
The disturbance of grey slurries so that lime slurry loses the condition of sluggish accumulation, reduces the lime slurry of viscosity in mesh
Dead time is conducive to lime particle and passes through strainer, the time that mesh has been delayed to block significantly, and due to the end of agitating paddle
End close to filter basket inner wall, therefore can when rotated will be adhered to filter basket on slurries scrape, further delayed mesh block when
Between, it is only necessary to periodic cleaning is carried out to strainer, can both save cost of human resources, can also promote flue gas purification system can
By property, ensure being smoothed out for production.
