Description
Technical Field
The utility model relates to an electrolysis accident chlorine negative pressure water seal arrangement.
Background
The ionic membrane caustic soda device is characterized in that wet chlorine from an electrolytic cell enters a chlorine washing tower for washing and cooling, and an accident positive pressure water seal and an accident negative pressure water seal are arranged on a chlorine header pipe in front of the chlorine header pipe. Chlorine gas fed to the scrubber if the pressure in the electrolysis system is too highThe positive pressure water seal can be broken, and the chlorine gas is directly discharged into an accident chlorine gas device; as the chlorine-hydrogen treatment adopts the chlorine turbine compressor to convey the chlorine, the chlorine main pipe is provided with the accident negative pressure water seal, and the air can be automatically sucked in under the abnormal state, thereby preventing the generation of large negative pressure. The chlorine positive pressure water seal liquid seal height before the chlorine water washing tower is 900mmH2And O. When the electrolytic cell is stopped in a chain manner, the chlorine pipeline system generally forms 200-300 mmH2If the negative pressure of the O is too large, the water seal is broken, so that the pipeline, the equipment and the like are prevented from being deflated. During normal production, the negative pressure extracted by the chlorine turbine compressor is too high and damages pipelines and equipment due to abnormal conditions, so that the height of the chlorine negative pressure water seal is set to be 500 mmH2O。
Disclosure of Invention
The utility model provides an electrolysis accident chlorine negative pressure water seal arrangement, it can guarantee that chlorine system breaks down, and chlorine malleation is greater than 500 mmH2And no chlorine gas overflows from the chlorine negative pressure water seal during O.
The utility model adopts the following technical scheme: the chlorine negative pressure water seal device for the electrolysis accident comprises a chlorine liquid seal tank and a chlorine negative pressure water seal tank, wherein an air outlet and an air breaking port are arranged at the upper part of the chlorine negative pressure water seal tank, the air outlet is communicated with the chlorine negative pressure water seal tank, a water seal pipeline is arranged in a water seal gap between the air breaking port and the liquid level of the chlorine negative pressure water seal tank, the air breaking port is communicated with the chlorine negative pressure water seal tank through the water seal pipeline, an overflow port is arranged on the side surface of the chlorine negative pressure water seal tank and is divided into a branch I and a branch II, the branch I is communicated with the air outlet through a water outlet pipe I, the branch II is communicated with the chlorine liquid seal tank through a water outlet pipe II, and an outlet communicated with a chlorine water collecting tank is arranged on the.
The height of the water seal pipeline is 900mmH2And O. The liquid level height in the chlorine liquid seal tank is 3000mmH2O。
The utility model discloses following beneficial effect has: after the technical proposal is adopted, the upper part of the chlorine negative pressure water-sealed tank of the utility model is provided with an air outlet and an air breaking opening,the chlorine negative pressure water-sealed tank is communicated with the air outlet, a water-sealed pipeline is arranged in a water-sealed gap arranged between the air breaking port and the liquid level of the chlorine negative pressure water-sealed tank, the air breaking port is communicated with the chlorine negative pressure water-sealed tank through the water-sealed pipeline, an overflow port is arranged on the side face of the chlorine negative pressure water-sealed tank, the overflow port is divided into a branch I and a branch II, the branch I is communicated with the air outlet through a water outlet pipe I, the branch II is communicated with the chlorine liquid-sealed tank through a water outlet pipe II, an outlet is arranged on the side face of the chlorine liquid-sealed tank and communicated with a chlorine water collecting tank, the water outlet pipe of the original negative pressure water-sealed overflow port is connected into the chlorine2O, thus ensuring that the chlorine system has a fault and the positive pressure of the chlorine is more than 500 mmH2And no chlorine gas overflows from the chlorine gas negative pressure water seal during O, although the chlorine gas turbine breaks down for many times, the chlorine gas system has large positive pressure, and the chlorine gas positive pressure water seal is broken for several times, but the chlorine gas liquid seal tank is internally sealed by the chlorine gas negative pressure water seal so as to avoid the occurrence of the phenomenon of chlorine gas leakage.
