Description
Technical field
The present invention relates to a kind of dust arrester, especially a kind of dust arrester of grain drying tower.
Background technology
The dust arrester of grain drying tower can be divided into following three class successively according to the height of efficiency of dust collection：Pulse bag removes
Dirt device, centrifugal dust collector and gravity settling chamber, wherein, the efficiency high of sack cleaner is up to 99%, but on the too low ground of temperature
Fang Rongyi freezes, so should not typically use；And the efficiency of dust collection of gravity settling chamber only has 50% or so, for dust removal requirement height
Occasion and do not apply to, so all use centrifugal dust collector on existing grain drying tower, its efficiency of dust collection is typically left 80%
The right side, the efficiency of dust collection of centrifugal dust collector in existing dust arrester how is improved, the technology for turning into instantly in the urgent need to address is difficult
Topic.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of dust arrester of grain drying tower.
The technical solution adopted for the present invention to solve the technical problems is：A kind of dust arrester of grain drying tower, including
Centrifugal dust collector, flow-mixing blower fan and snail cylinder, the air inlet of the flow-mixing blower fan and the exhaust passage of drying tower connect, flow-mixing blower fan
Air outlet be connected with the air inlet duct of snail cylinder, the air inlet of the air outlet of snail cylinder connection centrifugal dust collector, snail cylinder it is upper
Portion sets rain hat, the top connection circulation pipe of the centrifugal dust collector, and the circulation pipe is connected to the exhaust passage of drying tower
It is interior, the bottom connection cement output tank of centrifugal dust collector, the bottom connection airlock of the cement output tank.
Further, the snail cylinder includes outside snail cylinder inner ring, flow deflector, snail cylinder plate inner ring and snail cylinder plate successively from inside to outside
Circle, the waste gas with granule dust is concentrated between the snail cylinder plate inner ring and snail cylinder plate outer ring.
The beneficial effects of the invention are as follows：The efficiency of dust collection of the dust arrester of the present invention is removed by centrifugal dust collector and snail cylinder
Dirt efficiency superposition, efficiency improve to 97% or so, meet the environmental requirement of grain drying tower, also dry and produce for lift grain
The core competitiveness of product lays the first stone.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of dust arrester of grain drying tower, including centrifugal dust collector 1, flow-mixing blower fan 2 and snail cylinder
3, the air inlet of flow-mixing blower fan 2 and the exhaust passage of drying tower are connected, and the air outlet of flow-mixing blower fan 2 is connected with the air inlet duct of snail cylinder 3,
The air inlet of the air outlet connection centrifugal dust collector 1 of snail cylinder 3, the top of snail cylinder 3 set rain hat 4, centrifugal dust collector 1
Top connects circulation pipe 5, and circulation pipe 5 is connected in the exhaust passage of drying tower, the bottom connection cement output tank 6 of centrifugal dust collector 1,
The bottom connection airlock 7 of cement output tank 6.
As shown in figures 2-3, snail cylinder 3 includes snail cylinder inner ring 31, flow deflector 32, the and of snail cylinder plate inner ring 33 successively from inside to outside
Snail cylinder plate outer ring 34, the waste gas with granule dust is concentrated between snail cylinder plate inner ring 33 and snail cylinder plate outer ring 34.
Operation principle：After flow-mixing blower fan 2 washes out the waste gas containing dust impurities out of grain drying tower, granule dust exists
It can enter under centrifugal action along the wall of snail cylinder 3 in snail cylinder runner, finally enter in centrifugal dust collector 1；Again by centrifugation
Power acts on, and a part of dust is settled down along cement output tank 6, is finally excluded from airlock 7, another part dust-laden exhaust gas is through following
It is again introduced into after endless tube 5 in the exhaust passage of grain drying tower, carries out final dusting.Waste gas after dedusting can drain into greatly from rain cap 4
In gas.Waste gas with granule dust under the action of the centrifugal force, be concentrated mainly on snail cylinder plate inner ring 33 and snail cylinder plate outer ring 34 it
Between, the dust-laden exhaust gas between snail cylinder plate inner ring 33 and snail cylinder plate outer ring 34 enters in snail cylinder runner naturally, the He of snail cylinder plate inner ring 33
In the presence of flow deflector 32, granule dust can launch back dust-laden exhaust gas between snail cylinder inner ring 31, minute dusts particle meeting
By the inside of snail cylinder inner ring 31 finally from 4 mouthfuls of discharges of rain cap.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
