Further, the other side of the second flange ring 131 is provided with a flow collecting pipe 133, the sectional area from the inlet to the outlet of the flow collecting pipe 133 is gradually reduced, the gas is collected by reducing the sectional area of the outlet, bubbles in the flow guide pipe 210 are reduced, the outlet of the flow collecting pipe 133 is provided with a butt joint pipe 136, and the other end of the butt joint pipe 136 is connected to the flow guide pipe 210.

Still further, a first pair of interfaces 212 is arranged at two ends of the connecting pipe 211, an internal thread ring 213 is screwed on the first pair of interfaces 212 for sealing and preventing leakage, a plurality of second pairs of interfaces 223 are arranged at two sides of the water tank 220, the second pairs of interfaces 223 are connected with the flow guide pipe 210, the first pair of interfaces 212 are screwed on the second pair of interfaces 223, and the threaded connection facilitates disassembly and replacement.

In addition, the cover plate 230 is arranged above the water tank 220, the plurality of screws 233 are arranged on two sides of the cover plate 230, the screws 233 penetrate through the cover plate 230, the screws 233 are in threaded connection with the upper portion of the water tank 220, the plurality of handles 231 are arranged on the cover plate 230 and the water tank 220, the anti-slip sleeve 232 is sleeved outside the handles 231, the cover plate 230 can be detached, and scale in the water tank 220 can be conveniently cleaned.

In addition, water tank 220 below is equipped with a plurality of horizontal poles 241, and horizontal pole 241 both sides are fixed with side dead lever 240, and side dead lever 240 and horizontal pole 241 are equipped with the multiunit, constitute frame construction and make things convenient for heat dissipation box installation pipeline, are connected with montant 242 between the side dead lever 240, are equipped with baffle 243 on the horizontal pole 241 of outside, and montant 242 bottom is equipped with callus on the sole 244, preferably rubber materials, promotes the frictional force and provides the buffering simultaneously.

In the embodiment, when the fractionating tower 110 is opened for operation, the corresponding discharge port will generate gasified mineral oil, at this time, since the discharge port is blocked by the block 155 in the flow gathering structure 150, the block 155 will reduce the amount of air discharged to the outside so as to reduce bubbles in the condensation pipe, then the internal gasified mineral oil will be accumulated slowly, thereby increasing the internal pressure, until the pressure is sufficient, the block 155 will be pushed open so as to increase the discharge amount, meanwhile, since the internal gasified mineral oil is sufficient, the increased discharge amount will not generate a large amount of bubbles, further, when the internal pressure is too high, the plug 1410 of the pressure reducing structure 140 will be pushed open by gas, thereby further increasing the discharge amount, then when the gasified mineral oil enters the flow guiding pipe 210, the flow guiding pipe 210 is located in the water tank 220, and the gasified mineral oil in the flow guiding pipe 210 is cooled by cold water flowing in the water tank 220, the draft tube 210 is connected by the connection tube 211, and the cooling time can be controlled by controlling the flow distance by arbitrarily combining the number of works of the draft tube 210.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
