Description
Technical Field
The utility model relates to a heat exchanger field particularly, relates to a cauldron formula floating head heat exchanger.
Background
The heat exchanger is a universal device widely applied in petrochemical industry, power industry, medicine industry, metallurgy industry, refrigeration industry, light industry, food industry and other industries. The current domestic heat exchangers are divided into the following parts according to functions: heat exchangers, condenser coolers, evaporators, reboilers, etc.
Most of the existing reboilers are designed into a U-shaped tube type kettle structure with a gas phase boiling space on the shell side, the structure of the reboiler is only provided with one tube plate, two ends of each tube are fixed on the same tube plate, the tubes can freely stretch and retract without thermal stress, and the thermal compensation performance is good; the tube pass adopts the multiple tube passes, and the flow is longer, and the velocity of flow is higher, and heat transfer performance is better, and bearing capacity is strong, and the tube bank can be taken out in the casing, and easy access and washing, and simple structure, the cost is cheap (see figure 1).
However, the U-tube heat exchanger also has a certain disadvantage that the medium in the tube must be cleaned, otherwise the medium in the tube will be deposited in the U-bend tube and is not easy to clean, thereby losing the effect of heat exchange.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at overcomes the above-mentioned not enough of current heat exchanger, provides a cauldron formula floating head heat exchanger.
In order to achieve the above object, the utility model adopts the following technical scheme:
a kettle type floating head heat exchanger is characterized in that a floating tube plate and an arched end socket are arranged at the other end of the heat exchanger, the floating tube plate and the arched end socket are both fixedly connected with a floating head flange, and the floating tube plate, the floating head flange and the arched end socket enclose a cavity; the heat exchange tube is a straight tube, one end of the heat exchange tube is fixed on the fixed tube plate, the other end of the heat exchange tube is fixed on the floating tube plate, and the heat exchange tube is communicated with the cavity.
Preferably, the floating tube plate is connected with the floating head flange through a bolt, and the arched end socket is welded and fixed with the floating head flange.
The utility model discloses following beneficial effect has: the utility model discloses in, the cavity that unsteady tube sheet, floating head flange and arch head are constituteed is equivalent to U type bend section, can reach the same function, and the heat exchange tube becomes the straight tube by U type pipe, has avoided the problem of medium siltation in the heat exchange tube, and because floating head flange passes through bolted connection with unsteady tube sheet, even if the medium siltation also conveniently dismantles and washs in the cavity appears.
