Abstract

The invention provides a union type single tube pass floating head heat exchanger, and belongs to the heat exchanger field; the tube pass of the union type single tube pass floating head heat exchanger comprises a floating tube plate, a barrel body and a head connected in sequence; the head is connected with a floating head joint pipe; an outer head cover of a shell pass is provided with an outer head cover joint pipe; one portion of the outer head cover joint pipe is positioned on the inner side of the outer head cover, and the other portion extends outside of the outer head cover; on the inner side of the outer head cover, the outer head cover joint pipe and the floating joint pipe are connected through a movable connector; the movable connector comprises two connecting pins, a fixator, a spacing cone, and a locking plug screw or pin bolt; the first end of one connecting pin is connected with the floating joint pipe, the first end of the other connecting pin is connected with the outer head cover joint pipe, and second ends of the two connecting pins are connected through the fixator, the spacing cone, and the locking plug screw or pin bolt.

Description

technical field [0001] The invention belongs to the field of heat exchangers, in particular to a joint-type single-tube-pass floating head heat exchanger. Background technique [0002] The single-tube floating head heat exchanger effectively combines the advantages of the floating head heat exchanger and the fixed tube sheet heat exchanger. It is also suitable for the situation where the pressure drop is small, easy to scale and needs to be cleaned. Commonly used structural types see figure 1 . figure 1 1 is a spherical head, 2 is an expansion joint, 3 is a clamping plate, 4 is a reverse flange, 5 is a pipe flange, and 6 is a flange. The structure of the tube box outlet of the floating head heat exchanger is widely used, but because these floating head connectors are all enclosed in the shell, it is inconvenient to install and overhaul, and the expansion joint bears the pressure of the tube side and the shell side at the same time, and the pressure between 5 and 6 The se...
