Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 to 6, a connection structure of rectifying column and condenser, including rectifying column 1 and condenser 2, first cavity 11 and second cavity 12 are split into from supreme down to rectifying column 1 is inside, be equipped with between first cavity 11 and the second cavity 12 and be used for gaseous inlet port 3 that passes through, be located inside bottom surface 4 of second cavity 12 is along 3 ring peripheries of inlet port and outwards is the downward sloping structure, be equipped with the delivery port in the second cavity 12, the delivery port can be connected with the water pump, first cavity 11 is connected with the reboiler of rectifying column 1 outside, condenser 2 is located in the second cavity 12.

The working principle is as follows:

the condenser 2 is arranged in the second cavity 12 of the rectifying tower 1, liquid is gasified by a reboiler, enters the second cavity 12 from the first cavity 11, and falls to the bottom surface 4 of the second cavity 12 under the action of the condenser 2, and the bottom surface 4 of the second cavity 12 is of a downward inclined structure outwards from the air inlet 3, so that the liquefied gas cannot flow back into the first cavity 11 and is discharged through the water outlet.

Further, referring to fig. 4, a cyclone separator 5 is disposed at the air inlet 3, an air outlet end of the cyclone separator 5 is disposed in the second cavity 12, a bolt may be used or a support portion may be disposed around the outer side of the cyclone separator 5, the cyclone separator 5 is disposed on the air inlet 3, and the specific structure of the cyclone separator 5 and the installation structure of the cyclone separator 5 are well known technologies of those skilled in the art, and are not described herein.

As can be seen from the above description, the cyclone separator 5 is arranged, and the gas is dispersed around the second cavity 12 under the action of the cyclone separator 5, so that the gas can be prevented from being liquefied and then falling into the first cavity 11 again through the gas inlet 3.

Further, referring to fig. 5 and 6, the condenser 2 is a spiral tubular structure, the spiral tubular structure is horizontally arranged, the plurality of layers of condensers 2 which are spiral tubular structures are sequentially arranged in the second cavity 12 from bottom to top, one end of the outer side of the spiral tubular structure is an input end and used for introducing external cooling media, and one end of the inner side of the spiral tubular structure is an output end and connected with the L-shaped pipe 21 and used for discharging the cooling media in the condenser 2.
