The utility model discloses can prevent that cryogenic liquid from dropping on the air separation column body, eliminate the accident hidden danger.
Description
Technical Field
The utility model relates to an air separation column cold box flange weeping protector.
Background
The air separation tower of the steel plant is used for separating oxygen, nitrogen, argon and other gases in the air by utilizing the difference of the boiling points of the oxygen, the nitrogen, the argon and other gases, and the rectification of the air is to use the different volatility of various components of the air, namely the different vapor pressure of the components at the same temperature to carry out multiple partial evaporation and partial condensation on the liquid air, thereby achieving the purpose of separating the components. The whole rectification, heat exchange and condensation processes are all finished in the air separation column cold box, so that the effect of the cold box is very important. The outer side of the air separation tower cold box is provided with a flange for conveying and connecting a valve for low-temperature liquid at-196 ℃ in the air separation tower, a cold box flange sealing gasket is frequently leaked in the operation process, the low-temperature liquid is leaked out from the flange and drops on the outer wall of the air separation tower, and the cold and hot alternate action often causes the deformation of the outer wall of the air separation tower and even the occurrence of fracture accidents.
Disclosure of Invention
An object of the utility model is to provide an air separation tower cold box flange weeping protector can prevent that cryogenic liquid from dropping on the air separation tower body, eliminates the accident hidden danger.
The utility model aims at realizing like this, an air separation tower cold box flange weeping protector, including air separation tower cold box manhole gland, one is connecing the liquid cover through fastening bolt seal interval spiral-lock in this gland outside, connects the liquid cover for two upper and lower halves subdivision formula structures, connects a fluid-discharge tube in the bottom of liquid cover, and the fluid-discharge tube is L shape, is setting up a temperature probe in the upper portion body of fluid-discharge tube, is installing a solenoid valve on the lower part body of fluid-discharge tube, the temperature probe pass through the PLC controller with the solenoid valve link to each other.
The utility model discloses installing the temperature probe additional on sealed liquid receiving cover, installing the solenoid valve additional on liquid receiving pipeline, introducing valve and temperature signal to the PLC controller, when the detection temperature is less than-50 ℃, the system considers the valve flange weeping, and the flowing back is opened automatically to the solenoid valve. The utility model discloses improve the security of equipment body greatly, prevented that cryogenic liquid from dropping on the equipment body, prevented that the air separation tower shell from receiving the cold deformation. The device is convenient to install and disassemble, and the liquid receiving cover adopts a split structure, so that the device is convenient to disassemble and install and good in using effect.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is a schematic side view of the present invention.
Detailed Description
The utility model provides an air separation tower cold box flange weeping protector, as shown in figure 1, figure 2, including air separation tower cold box manhole gland 1, a liquid cover 2 is being connect through fastening bolt seal interval spiral-lock in this gland 1 outside, connect liquid cover 2 to be two upper and lower halves subdivision formula structures, connect the bottom of liquid cover 2 and connect a fluid-discharge tube 5, fluid-discharge tube 5 is L shape, is setting up a temperature probe 6 in the upper portion body of fluid-discharge tube 5, is installing a solenoid valve 4 on the lower part body of fluid-discharge tube 5, temperature probe 6 pass through PLC controller 3 with solenoid valve 4 link to each other.
The utility model discloses during the use, the liquid of leakage is through connecing in liquid cover 2 gets into fluid- discharge tube 5, 6 perceptions of temperature probe low temperature, have liquid leakage after, open solenoid valve 4 through PLC controller 3 and carry out timely flowing back, even the easy access personnel discovery and troubleshooting.
