Description
Technical field
The present invention relates to steam drying technical fields, and in particular to a kind of large-scale metallurgical material heat-exchanging drying arrangement.
Background technology
It is steam dryer that collocation zinc leaching residue KIVCET, which directly refines lead project procedure for preparation, it is to utilize afterheat steam heat
Measure the key equipment that lead raw ore mixed material is dried.Steam dryer is in traditional direct heat transfer rotary dryer
On the basis of internal installed heat-exchange device additional（Structure is：Heat pipes are formed）, belong to indirect heat exchange drying equipment.Its heat exchange
Device is steam dryer core component, is tubulose conjoined structure, and steam is led in pipe, and outer contacted with material of pipe carries out heat exchange,
Steam carries out heat exchange by tube wall and material, and then material is dried.
Heat-exchange device is the main vulnerable part of steam drying machine equipment, and service life is determined according to material use condition,
General service life is about 2~3 years or so, after the pipe fitting of heat-exchange device is easily worn, is thinning, perforation is scrapped, heat exchange dress
Putting needs integral replacing, and primary about 10,000,000 yuan of entirety heat-exchange device parts replacement expense is such as introduced from Ku Maila companies of Finland,
Procurement cycle is long, costly, normal production can be smelted to lead and cost impacts.
Existing main problem is steam dryer heat-exchange device in use：
（1）, its service life according to material use condition determine, general service life is about to need integral replacing in 2~3 years or so,
The price of import Ku Maila steam dryer heat-exchange devices is extremely expensive, and procurement cycle is long.
（2）, heat-exchange device pipe fitting and drying machine inner barrel support frame and heat-exchanger rig pipe fitting gap original design
It is larger, drum dryer running body produce when heat-exchanger rig pipe fitting easily shake at support frame filler ring, displacement, exchange heat pipe fitting
It is easily worn, perforates at support, at first batch of imported with original packaging heat-exchange device pipe fitting and drying machine inner barrel support frame filler ring
Use less than just be worn within 6 months or so it is thinning.
（3）, heat-exchanger rig its pipe fitting header wooden partition easily by material corrosion, the thinning perforation leakage vapour of abrasion, service life is short.
Invention content
The object of the present invention is to provide a kind of large-scale metallurgical material heat-exchanging drying arrangement, to solve drying machine heat exchange dress
The problem of procurement cycle long, with high costs, easy to wear corrosion put and short service life.
The invention is realized in this way a kind of large-scale metallurgical material heat-exchanging drying arrangement, by multiple rows of heat-exchanger rig with same
Heart circle mode is evenly distributed in drum dryer body shell body, and the heat-exchanger rig is fixed on drum dryer body shell by support frame
In vivo；The heat-exchanger rig includes two big pipes for being mounted on mouthpiece, and the other end of the big pipe is provided with casing end cap,
Two big pipe front and rear parts are connected respectively by header, and evenly distributed tubule is provided between the header, described small
With being connected between header, the tubule is fixedly mounted pipe with big pipe by the fixation floor that horizontal homogeneous is set；The header
It is formed by non-porous side plate, external arc plate, by hole side plate and Inner arc plate, it is described to there is hole side plate mutually to be welded with tubule, and by logical
Hole is connected with tubule；The big pipe is fixed in the support ring of support frame.
Further, the thickness of the header and big pipe and tubule is 3-5mm.
Further, the junction of the big pipe and support ring is set as the protective case that packet weldering thickness is 3-5mm.
Further, the number of turns of the heat-exchanger rig assembly is 5 ~ 7 circles.
The beneficial effects of the invention are as follows：
Compared with traditional direct heat transfer rotary dryer, steam dryer has the following advantages that：
（1）, product quality is easy to ensure：Since material and dried medium are not directly contacted with, dried medium is avoided to material
Secondary pollution；
（2）, heat utilization rate it is high：The condensed water that steam is formed after exchanging heat can be easily recycled, improves the utilization rate of thermal energy；
（3）, the thermal efficiency it is high：The thermal efficiency of indirect heat dryer is mainly reflected on exhaust flow, with direct drying machine
It compares, the exhaust flow of indirect heat dryer is small, thus the thermal energy taken away is just few.It is, in general, that reach identical drying
Quality, thermal energy needed for indirect dryer are the 1/2~1/3 of direct-type drying machine, and with the drop of finished product target humidity
Low, the advantage of indirect dryer can dramatically increase；
（4）, low stain：Exhaust flow is small, is not easy to carry dust secretly.Simultaneously because the content of hygroscopic water can be very high in tail gas, favorably
The recycling of waste heat in some special solvents and tail gas；
（5）, it is at low cost：Used high-temperature medium is that boiler directly generates, and is that steam is also just filled without tail gas clean-up
It puts；Steam dryer heat-exchanger rig（Heat pipes）Production domesticization research substitution realizes production domesticization, reduces rapid wear from external import
For part spare part from external procurement cycle, the spare parts purchasing period is short, while saves a large amount of external spare parts purchasing expenses, it is ensured that directly refines lead
Continuous production；
（6）, treating capacity it is big：Can continuous production, equipment yield is big, suitable for the continuous drying miberal powder of high-volume；
（7）, service life it is long：The preferably domestic two-phase alloys steel of heat-exchanger rig tubing, board selection corrosion resistant, wear-resisting property, takes
Generation external inlet fitting, makes the tubing service life of heat-exchanger rig approach and reach imported product service life；Heat-exchanger rig pipe
Part header, which connect plate thickness with large and small pipe, increases by 3~5mm, enhances its wearability, extends heat-exchanger rig service life；It is filled in heat exchange
It is 3~5mm protective cases to put big pipe outer wall packet weldering thickness at pipe fitting and inner barrel support frame support ring, protective case mainly have with
Lower two effects：（1）, eliminate the problem of gap is excessive at the big pipe of heat-exchanger rig and support frame support ring, it is therefore prevented that cylinder
The situation that heat-exchanger rig pipe fitting shakes and is subjected to displacement at support frame support ring during operation；（2）, work as heat-exchanger rig
Pipe fitting is subjected to displacement at support frame support ring when wearing, and protects big tube wall, when protective case abrasion is big, can be determined
Phase replaces protective case, so as to extend heat-exchanger rig pipe fitting service life.
