Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
As shown in Fig. 1 ~ 5, the utility model includes vertically disposed shell side section 6, and upper tube box 1 and lower tube box 8 are fixed respectively
It is connected to the upper and lower ends of shell side section 6.Shell side section 6 includes cylinder 63, and the both ends of cylinder 63 are respectively equipped with upper perforated plate 61 and down tube
Plate 62, several heat exchanger tubes 7 are uniformly arranged in cylinder 63, and the both ends of heat exchanger tube 7 are separately connected upper perforated plate 61 and lower perforated plate 62.
Several dispensing heads 4 being arranged in upper tube box 1 are separately positioned on the upper end of each heat exchanger tube 7, the quantity and heat exchange of dispensing head 4
The quantity of pipe 7 is identical, and as shown in Figure 4,5, in a tubular form, the upper end of dispensing head 4 is symmetrically arranged with the elongated slot of 2 axial directions to dispensing head 4
41, elongated slot 41 and the inner hole of dispensing head 4 are tangent.The distributing disc 3 that 4 top of dispensing head is arranged in is connected by height adjustment mechanism 5
Upper perforated plate 61, distributing disc 3 include horizonal base plate 33 and shell ring 32, and distributing disc is formed by welding with shell ring 32 in circular horizonal base plate 33
3, horizonal base plate 33 is equipped with several distribution holes 31, and distribution hole 31 and heat exchanger tube 7 mutually stagger setting (Fig. 2), by distribution
The feed liquid that hole 31 is fallen directly will not enter heat exchanger tube 7 by dispensing head 4, and the setting quantity of distribution hole 31 is true according to feed liquid flow
It is fixed.Height adjustment mechanism 5 includes the fixed block 51 being fixedly welded on upper perforated plate 61, and fixed block 51 is equipped with threaded hole, vertically
