Description
Technical field
The utility model relates to a kind of tempering tower more particularly to a kind of tempering tower heating box devices, belong to lubricating utensil skill
Art field.
Background technique
Tempering tower heating box device is to be formed by parallel heat exchangers multiple inside tempering tower heater box with heating compartment
Heating device, heat transferring medium such as steam is passed through into heat exchanger, to flow into tempering tower heater box inside material heat,
Become condensed water after steam heat release, is discharged from the cooling medium outlet of heater box.
Tempering tower heater box mainly has fixed heater box and telescopic heater box two ways, fixed heater box at present
Heat exchanger tube be evenly arranged on tube sheet, heat exchanger tube medium inlet end and media outlet end are welded with whole welding type cabinet respectively
It connects, heat exchanger tube both ends weld to form medium inlet end seal head and media outlet end seal head respectively with corresponding end socket, to make to change
The heat transferring medium of inside heat pipe and heat exchange can only be carried out into the intracorporal material of heater box, its working principle is that heat transferring medium from
Medium inlet end seal head flows uniformly into heat exchanger tube, after entering the intracorporal material heat exchange of fixed heater box, then leads to
Cross the discharge of media outlet end seal head.Because fixed heater box is whole welding type, heat exchanger tube and cabinet before and after logical heat transferring medium
Size of expanding with heat and contract with cold is asynchronous, makes that the weld seam at heat exchanger tube and welding box body is easy to appear cracking or even heat exchanger tube splits, and causes
Heat transferring medium reduces heat transfer effect even contaminated material, simultaneously because welding structure by flowing into material at crack and cracking
And the limitation of bulk, later period are difficult to repair and replace heat exchanger tube；And due to heat exchanger tube alternating expression in fixed heater box
It arranges, constantly hits friction with heat exchanger tube in material dropping process, the wall thickness of heat exchanger tube is more and more thinner, reduced service life, and
And the heat exchange area of same volume heater box is smaller.
The heat exchanger tube of telescopic heater box is also evenly arranged on tube sheet, heat exchanger tube medium inlet end and media outlet end point
Not with extension type welding box body, heat exchanger tube both ends are welded with corresponding end socket respectively to form medium inlet end seal head and medium goes out
Mouth end seal head, to make the heat transferring medium inside heat exchanger tube that can only carry out hot friendship with into the intracorporal material of telescopic heater box
It changes, its working principle is that heat transferring medium flows uniformly into heat exchanger tube from medium inlet end seal head, with the telescopic heating of entrance
After the intracorporal material heat exchange of case, then pass through the discharge of media outlet end seal head.The heat exchanger tube of telescopic heater box is still adopted with end socket
With welding form, such as heat exchanger tube partial failure, the later period is still difficult to repair and replace heat exchanger tube；Simultaneously because heat exchanger tube in cabinet
It arranges in alternating expression, constantly hits friction in material dropping process with heat exchanger tube, heat exchange thickness of pipe wall is more and more thinner, service life contracting
It is short；The heat exchange area of same volume heater box is smaller.
Utility model content
