Abstract

The utility model discloses a connecting structure of a main condensation evaporator and a lower tower. The connecting structure comprises a lower tower ring plate (2) and a ring plate supporting rib plate (3). The lower tower ring plate (2) is located at the bottom of the main condensation evaporator (1), one face of the ring plate supporting rib plate (3) makes contact with the lower tower ring plate (2), the other face of the ring plate supporting rib plate (3) makes contact with the lower tower (4), and liquid draining holes are formed in the lower tower ring plate (2). According to the connecting structure of the main condensation evaporator and the lower tower, a potential explosion hazard caused by hydrocarbon accumulation and concentration due to the fact that a gap between a main condensation evaporator barrel body and a T-shaped aluminum level ring is small is eliminated, structural design does not influenced by the sectional dimension of T-shaped aluminum, influence from rolling section bars on material performance is avoided, and the ring plate supporting rib plate structure reduces the thickness of a ring plate and increases rigidity of a lower tower end socket transition section.

Description

Main condenser evaporimeter and following tower syndeton
Technical field
The utility model relates to the Deep Cooling Method air-separating plant, particularly main condenser evaporimeter and following tower syndeton.
Background technology
Be traditional main condenser evaporimeter and following tower syndeton as Fig. 3, adopt T type aluminium (5) that both are connected, this structure need increase the material of main cold cone changeover portion and the direct tube section that is connected with T type aluminium (5), need process the transition groove thick, thin barrel of following tower (4), need girth weld simultaneously, also need to carry out Non-Destructive Testing after finishing, so just increased the consume of manufacturing procedure and material.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of main condenser evaporimeter simple in structure and following tower syndeton are provided.
The purpose of this utility model is achieved through the following technical solutions: main condenser evaporimeter and following tower syndeton, it comprises tower ring flat-plate and ring flat-plate bearing rib down, following tower ring flat-plate is positioned at the main condenser base of evaporator and the main condenser evaporimeter is sealed, ring flat-plate bearing rib one side contacts with following tower ring flat-plate, one side contacts with following tower in addition, be used for supporting tower ring flat-plate and Xia Ta down, reduced the thickness of time tower ring flat-plate, described following tower ring flat-plate is provided with outage, and liquid oxygen, raffinate all can flow out from descending the outage on the tower ring flat-plate.
The utlity model has following advantage:
One, the utility model has been eliminated the hydrocarbon that main condenser evaporator tube and T type aluminium horizontal loops gap brings for a short time and is gathered and concentrate the potentiality explosion danger that brings.
Two, structural design is not subjected to the influence of T type aluminium sectional dimension, the influence of having avoided rolling section bar that material property is caused.
Three, ring flat-plate bearing rib structure decrease of the present utility model increased the rigidity of time tower end socket changeover portion ring flat-plate thickness the time.
Description of drawings
Fig. 1 is the cold interior one-board of master of the present utility model and following tower ring flat-plate connection diagram;
Fig. 2 is the cold interior multi-plate and following tower ring flat-plate connection diagram of master of the present utility model;
Fig. 3 is existing main cold and following tower T type aluminium connection diagram;
Among the figure, 1-main condenser evaporimeter, tower ring flat-plate under the 2-, 3-ring flat-plate bearing rib, tower under the 4-, 5-T type aluminium.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As Fig. 1, Fig. 2, shown in Figure 3, main condenser evaporimeter and following tower syndeton, it comprises tower ring flat-plate 2 and ring flat-plate bearing rib 3 down, following tower ring flat-plate 2 is positioned at main condenser evaporimeter 1 bottom and with 1 sealing of main condenser evaporimeter, ring flat-plate bearing rib 3 one sides contact with following tower ring flat-plate 2, and one side contacts with following tower 4 in addition, be used for supporting tower ring flat-plate 2 and following tower 4 down, reduced the thickness of time tower ring flat-plate 2, described following tower ring flat-plate 2 is provided with outage, and liquid oxygen, raffinate all can flow out from descending the outage on the tower ring flat-plate 2.

Claims (2)
