FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the high-efficiency heat exchange device comprises a shell-and-tube heat exchanger 1, a fan 2 and a venturi high-efficiency mixer 3.
The shell-and-tube heat exchanger 1 comprises a shell 11 and a heat exchange coil 12; the shell 11 is provided with a shell side inlet 111, a shell side outlet 112, a shell side liquid outlet 113, a tube side inlet 114 and a tube side outlet 115. The shell-side outlet 112 is connected to the nozzle end 31 of a venturi high-efficiency mixer 3 via a first conduit 4, and the fan 2 is mounted on the first conduit 4. The shell-side liquid outlet 113 of the shell-type heat exchanger is communicated with the suction chamber 32 of the venturi high-efficiency mixer 3 through the second pipeline 5.
Furthermore, the high-efficiency heat exchange device also comprises a protective shell 6. The shell-and-tube heat exchanger 1, the fan 2 and the high-efficiency Venturi mixer 3 are all installed in the protective shell 6, a fluid inlet pipe 71 is connected to a shell side inlet 111 of the shell-and-tube heat exchanger, and a fluid outlet pipe 72 is connected to a diffusion pipe end 33 of the high-efficiency Venturi mixer 3. A circulating water inlet pipe 81 and a circulating water outlet pipe 82 are respectively connected to a pipe pass inlet 114 and a pipe pass outlet 115 of the shell-and-tube heat exchanger, and the fluid inlet pipe 71, the fluid outlet pipe 72, the circulating water inlet pipe 81 and the circulating water outlet pipe 82 respectively extend out of the protective shell 6.
The heat exchange coil of the shell-and-tube heat exchanger 1 is a spiral coil.
The working principle of the utility model is as follows: the starting fan 2 extracts the non-condensable gas in the shell 11 into the venturi high-efficiency mixer 3 through the first pipeline 4, and meanwhile, under the action of negative pressure, condensed water in the shell 11 enters the suction chamber 32 of the venturi high-efficiency mixer 3 through the shell-side liquid discharge port 113 and the second pipeline 5 and is mixed with the non-condensable gas to form a gas-liquid two-phase heat taking medium.
The above description is only for the purpose of illustrating the technical solutions of the present invention, and those skilled in the art can make simple modifications or equivalent substitutions on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
