Mouth spray is uniformly provided with down, and mouth spray is covered in directly over cooling tube constriction 21 without dead angle；Air blower underneath type, inwardly blowing, does not have
There are erosion and the corrosion to blower fan that hot moisture insulate to motor, improve the service life of air blower；Inwardly dry and air inducing
The air inducing of cooling tower is cooperateed with mutually, is accelerated air inducing efficiency, is further improved cooling effect；Moreover, blowing can also delay spray
The falling speed on cooling tube constriction of water drenching, accelerates the evaporation of plate constriction outer surface moisture film, and improves evaporation capacity, carries
The high heat exchange amount with soft water in plate constriction, induced draft cooling tower, underneath type air blower, the combination of spray equipment three have very strong
Synergy and effect.The air blower 5 is axial flow blower, and aspect of blowing efficiency is high, can be in running order for a long time；It is described to drive
Dynamic component 64 is Electrohydraulic push rod, and advance is long, flexible；The bottom of support 63 is fixedly connected with directive wheel, and guide support edge is long
Spend direction movement, rapid operation, it is possible to realize automation mechanized operation；The periphery of base 1 can set windbreak, it is to avoid impurity
System is blown into, and makes system ambient air pressure stable, plays a part of stable axial flow blower.
The tubular type blast-furnace soft water evaporative air-cooling system of the present embodiment, through measuring and calculating, is ensureing continuous service without maintenance
On the basis of, and the tubular type blast furnace evaporation air cooler of overhead type blower fan structure compares, cooling effectiveness improves more than 30%.
Embodiment 4
The tubular type blast-furnace soft water evaporative air-cooling system of the present embodiment, basic structure and descaling method be the same as Example 2, it is different and
The improvement is that：In step 2, while starting Electrohydraulic push rod, start axial flow blower, induced draft cooling tower can be played, underlying
Formula air blower, spray equipment, the synergy of the combination heat exchanging cooling of hairbrush, have further delayed under shower water
Stream, cooling effectiveness is further improved；The cleaning mixture jet pipe is rectangular tube, and width is slightly less than the gap between cooling tube bundle, side
Shape pipe can agree with the square gap between cooling tube bundle, and scale removal and the effect for preventing pipe scale from generating are more preferable.
Embodiment 5
The tubular type blast-furnace soft water evaporative air-cooling system of the present embodiment, basic structure and descaling method be the same as Example 2, it is different and
The improvement is that：Apparatus for eliminating sludge 6 is respectively provided with the both sides of the cooling tube constriction 21 of each section, cleaning mixture jet pipe beam 61 interts
Each apparatus for eliminating sludge 6 is linked between cooling tube constriction 21, and by chain device, each apparatus for eliminating sludge 6 is run simultaneously,
Advantage is to move apparatus for eliminating sludge 6 without the length direction along cooling tube constriction 21, and scale removal prevents the generation of pipe scale from more facilitating.
Schematically the utility model and embodiments thereof are described above, the description does not have restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So, if this area
Those of ordinary skill enlightened by it, do not departing from the case that the utility model creates objective, designed without creative
