Description
Technical field
Technical field
The invention belongs to chemical technology field, be related to converter catalyst in a kind of gas washing in SA production draws dress and screening plant,
Dress and screening plant and its application method are drawn more particularly to a kind of no pollution dust collector type catalyst.
Background technology
Phenomena such as hardened, poisoning, efflorescence, failure can be produced after sulfate system conversion catalyst long-term use, cause conversion ratio
Decline.Therefore, annual annual test, which need to carry out catalyst, draws dress, screening and backfill.At present, catalyst draws dress and uses pure manual work, that is, turns
After change device hot blow, cold blowing terminate, open each layer manhole and carry out Temperature fall, temperature is down to 45 DEG C or so after about 24h, draws dress personnel
In full rig catalyst is slowly shoveled into woven bag with spade into each layer of converter after protective articles, another bag bag proposes manhole
Outside, pour into sieve to be sieved, packed, prepare backfill.Because temperature height, dust content are big in converter, draw dress personnel and often make
It must climb out of that manhole is ventilative, cooling after industry half an hour, drawing to reinstall to fill out about needs 20 people continuously to work round the clock 7 days could to complete, work
Industry environment is poor, it is low to draw dress efficiency.Draw dress process and want supporting and carry out safeguard measure, prevent that catalyst from drenching with rain failure.
The content of the invention
Present invention aims at draw the problem of dress operating environment is poor, efficiency is low for catalyst, there is provided a kind of no pollution is inhaled
Dirt device formula catalyst draws dress and screening plant.
The present invention adopts the following technical scheme that:A kind of no pollution dust collector type catalyst draws dress and screening plant, including base,
Base is provided with scrubbing tower, and scrubbing tower top is provided with exhaust outlet, and wash tower bottoms configure one and are used to collect taking out for dust precipitation

Wash and communicated between tower top and its other clear liquid groove top set by communicating pipe, clear liquid groove is provided with washing pump, washing pump output
End is connected with liquid pipe, the top that upper liquid pipe is passed in scrubbing tower, and the upper liquid pipe passed in scrubbing tower is provided with atomizer, clearly
Liquid bath top is communicated with the upper liquid pipe being exposed to outside scrubbing tower by pipeline section, and scrubbing tower bottom is provided with air-introduced machine and exported with air-introduced machine
End communicates, and air-introduced machine input is connected with fans entrance flexible pipe, and fans entrance flexible pipe communicates with screening chuck bottom, sieves chuck
Top is connected with flexible pipe, and the entrance point of flexible pipe is provided with the catalyst suction inlet that caliber reduces.
Further, flexible pipe is provided with portable pull bar and clip.
Further, the bottom for sieving chuck is connected with packed control valve by mounting flange.
Further, flexible pipe and fans entrance flexible pipe use reinforced plastics flexible pipe.
Further, screening chuck uses closed netted cylinder.
Further, air-introduced machine is provided with the adjustable distribution box of supply frequency.
Further, air-introduced machine output end is provided with control valve.
Further, clear liquid groove top end is communicated with the upper liquid pipe being exposed to outside scrubbing tower by pipeline section, is provided with back in the pipeline section
Flow valve.
Further, the bottom of clear liquid groove is provided with the apocenosis mouth for discharging cleaning solution.
Another object of the present invention is to provide a kind of method for drawing dress and screening using said apparatus progress catalyst, specifically
Comprise the following steps:
A. after converter cold blowing terminates, carry out catalyst using the device and draw and pretend industry, before operation, operating personnel are first to washing
Wash water filling in tower, open washing pump, the alignment of catalyst suction inlet is drawn at dress, closes packed control valve;
B. be then turned on air-introduced machine catalyst through catalyst suction inlet enter flexible pipe in fall into screening chuck sieved, it is intact
Catalyst sinks under gravity, after catalyst is sieving accumulation certain thickness in chuck, opens packed control valve, intact
Catalyst prepares backfill after pack regulating valve pack;Little particle crushes catalyst and taken out by air-introduced machine entrance negative pressure by mesh screens
Enter in scrubbing tower;
C. circulation fluid crushes catalyst to the little particle being pumped into scrubbing tower by atomizer atomisation and washed, small
Particle Breakage catalyst, because of broken collision, interception and cohesion between catalyst grit and drop, is broken when by vaporific space
Broken catalyst grit settles out into drawing and pulling type with drop and clears up groove, and drawing and pulling type cleaning groove upper clear supernate enters scrubbing tower and carries out one
Secondary precipitation, the clear liquid in scrubbing tower enter clear liquid groove after secondary precipitation by communicating pipe;
D. enter the clear liquid in clear liquid groove through upper liquid pipe to enter in scrubbing tower, through atomizer atomisation and broken catalyst
Grit contacts, and recycles.
The beneficial effects of the invention are as follows:After converter cold blowing terminates, catalyst can be carried out using the device of the present invention immediately and drawn
Pretend industry;Before operation, the first water filling into scrubbing tower of operating personnel, washing pump is opened, standing is outside manhole by suction inlet
Alignment is drawn at dress, opens air-introduced machine, catalyst after suction inlet, connection flexible pipe, screening chuck screening, through pack adjust by intact catalyst
Prepare backfill after saving valve pack, crush catalyst after air-introduced machine is pumped into scrubbing tower washing, recirculated water is sprayed into mist by atomizer
Shape, when by vaporific space, because of the collision between grit and drop, interception and cohesion, grit settles out with drop
Groove is cleared up into drawing and pulling type, clear liquid returns to clear liquid groove through secondary precipitation and recycled;The present invention is compact-sized, is readily transported, pacifies
Dress, operation, simple to operate, the efficiency for can make to draw dress, sieving catalyst greatly improves, and reduces the cost of overhaul and uses;Package unit is in
Confined space is run, and to operating environment, composing environment does not pollute;Operating personnel's quantity is at utmost reduced, it is strong to reduce hand labor
Degree, raises labour efficiency.
