Description
Technical field
It the utility model is related to a kind of industrial dust collector, especially a kind of receipts powder device applied to urea prilling tower, category
In environmentally friendly sciemtifec and technical sphere.
Background technology
Carbamide granulation technique can discharge substantial amounts of tail gas in process of production, contain substantial amounts of carbamide dust in tail gas, not
Carbamide dust through processing flies away everywhere with air, sedimentation, causes serious environmental pollution.In order to solve the tail of urea prilling tower
Gas emission pollution problem, the dust arrester of generally use washing at present, by setting washing dust arrester, profit on ground or tower top
With the dust granules in the fine liquid particles absorption tail gas of atomization, then set liquidceiver to reclaim cleaning solution, cleaning solution is passed through into steaming
The techniques such as hair remove moisture removal, reclaim urea raw material.
But these wash dust arresters firstly the need of substantial amounts of pipeline, water pump, the first-class equipment of spray is set, by water lotion
Body is transported to specified dedusting position, and cost is high.Secondly, it is necessary to expend substantial amounts of water during washing equipment operation maintenance
Resource and electric power resource, energy consumption are surprising.These all significantly increase the production cost of carbamide granulation technique.
Utility model content
The purpose of this utility model：A kind of carbamide granulation column overhead sack cleaner is aimed to provide, cheap, dedusting effect
Fruit is good, and can play the effect of carbamide dust recycling.
This carbamide granulation column overhead bladder type powder recepting device, including tower top pedestal and sack cleaner, also bag loop connecting
Portion, the sack cleaner are fixedly connected by loop connecting portion in tower top pedestal.
The loop connecting portion is welded in the H profile steel of carbamide granulation top of tower by a circle angle steel or channel-section steel bottom, another
End and dust collector box body sealing welding.
The sack cleaner includes filter bag, card and casing and formed, and casing is divided into two layers up and down by card, on card
Layer is toilet, and card lower floor is dedusting recovery room；The card is provided with opening, and filter bag is vertically installed in opening, described
Lower box opening, casing lower edge are arranged in loop connecting portion.
Air-introduced machine is additionally provided with the wall box, air-introduced machine includes air inlet and exhaust outlet, the air inlet of the air-introduced machine
Mouth is connected by pipeline with toilet.
Jetting deashing device is additionally provided with the casing.
This carbamide granulation column overhead bladder type powder recepting device provided by the utility model, using filter bag by carbamide dust physics
It is isolated in the dedusting recovery room of casing, in jetting deashing operation, the carbamide dust adsorbed on filter bag is peeled off, carbamide dust
Naturally fall back in urea prilling tower, avoid the waste of raw material.Meanwhile this bladder type powder recepting device, without setting additionally
Air-supply liquid-transport pipe-line, construction costs is greatly reduced, and filled in use without high energy consumptions such as extra water pump, evaporators
Put, greatly reduce O＆M cost.In addition, this bladder type powder recepting device, right during to urea prilling tower tail gas filtering
Carbamide dust retention in tail gas recycles, and carbamide dust under retaining can put into reproduction without carrying out extra process again
Activity, the loss of raw material is greatly reduced, has generated great economic benefit.

Embodiment
We come further to this carbamide granulation column overhead bladder type powder recepting device with reference to accompanying drawing and specific example below
Detailed description.
This carbamide granulation column overhead bladder type powder recepting device, including tower top pedestal 1 and sack cleaner, also bag loop connecting
Portion 10, the sack cleaner are fixedly connected by loop connecting portion 10 with tower top pedestal 1.The loop connecting portion is by a circle angle
Steel or channel-section steel bottom are welded in the H profile steel of carbamide granulation top of tower, the other end and dust collector box body sealing welding.
The sack cleaner is formed including filter bag 3, card and casing 2, and casing 2 is divided into two layers up and down by card, flower
Plate upper strata is toilet 4, and card lower floor is dedusting recovery room；The card is provided with opening, and filter bag 3 is vertically installed in opening
Place, the lower openings of casing 2, the lower edge of casing 2 are arranged in loop connecting portion 10.
Air-introduced machine 6 is additionally provided with the side wall of casing 2, air-introduced machine 6 includes air inlet 8 and exhaust outlet 9, the air-introduced machine 6
Air inlet 8 be connected by pipeline with toilet 4.In dedusting operation, air-introduced machine 6 constantly extracts the air in casing 2 out, urine
Dust particle in plain granulation tower in the tail gas of discharge is adsorbed by filter bag 3, and pure air is by filter bag 3, and opening from card
Enter toilet 4 at hole, successively by net gas passage 5, the air inlet 8 of air-introduced machine 6, finally from the row of exhaust outlet 9 of air-introduced machine 6
Go out.
Blowing type deashing device 7 is additionally provided with the casing 2.In deashing operation, air-introduced machine normal work, deashing device
7 are delivered to deashing air-flow in filter bag 3 by pipeline and nozzle, and the dust particle adsorbed on filter bag 3 is shaken off, falls back to and makes
In grain tower, prilling is continued to participate in.Because blast pass by pipeline and nozzle is delivered directly to the opening of filter bag 3, and pulse
Blast pass intensity is larger, the normal work of air-introduced machine, will not produce interference to pulse jet air-flow.In addition, in filtering operating mode
In, the raw material dust in urea prilling tower is constantly accumulated, and form larger by the physical barrier of filter bag on filter bag surface
Grain.In the jetting deashing operating mode of filter bag, particulate matter peels off from filter bag outer layer, falls back in urea prilling tower, continues to participate in and make
Grain technique.
