Abstract
The utility model relates to an electrolysis unit tank. An air outlet is formed in the top of the electrolysis unit tank, an inner sleeve and an outer sleeve are arranged at the opening part of the air outlet, external threads are arranged on the outer wall of the inner sleeve, internal threads matched with the external threads are arranged on the inner wall of the outer sleeve, and an annular groove is left between the inner sleeve and the outer sleeve. Through the improvement of the traditional electrolysis unit tank, the original air outlet sealed only through a single-layer sleeve is sealed through a double-layer sleeve, so that the better sealing performance is obtained, the safety is enhanced, and the possibility of chlorine gas leakage is reduced.
Description
Technical field
The utility model relates to a kind of sealed structure, is specifically related to the sealed structure at place, electrolysis unit groove air outlet.
Background technology
In chlorine industry usually by coming preparing chlorine gas, hydrogen and caustic soda with the electrolytic tank electrolysis saturated aqueous common salt.And the ion exchange membrane electrolytic saltwater is one of technique of present comparatively advanced production chlor-alkali.In this electrolyzer, with cationic exchange membrane, anolyte compartment and cathode compartment are separated.Cationic exchange membrane is different with the asbestos chorion, and it has the selection perviousness.It only allows Na+see through with a small amount of water molecules, and other ion is difficult to see through.Bottom from electrolyzer during electrolysis is injected toward the anolyte compartment through strict refining NaCl solution, toward the cathode compartment injected water.Cl-discharge in the anolyte compartment generates C1 2, emits from the air outlet at electrolyzer top, simultaneously Na+see through cationic exchange membrane with a small amount of water molecules to flow to cathode compartment.H+discharge in cathode compartment generates H 2, and also the air outlet from the electrolyzer top emits.But remaining OH-due to the obstruct that is subjected to cationic exchange membrane, can not shift to the anolyte compartment, so just enrichment gradually in cathode compartment has formed NaOH solution.Along with the carrying out of electrolysis, constantly inject table salt water in the anolyte compartment, to replenish the consumption of NaCl; Continuous injected water in the cathode compartment is with the consumption of make up water and the concentration of adjusting product NaOH.The alkali lye of gained is from cathode compartment top derivation.Because cationic exchange membrane can stop Cl-pass through, so contain NaCl impurity seldom in the NaOH solution that cathode compartment generates.The product that makes in this way is larger than the product concentration of producing with diaphragm electrolysis, and purity is high, and energy consumption is also low.But the sealing of the air outlet at traditional electrolyzer top generally takes the mode of rubber pad or single face screw thread to seal, and easily causes chlorine leakage, so there is potential safety hazard in this sealing means.
Therefore, the electrolysis unit groove air outlet sealed structure that a kind of good seal performance of exploitation and level of safety are high seems still for urgent.
The utility model content
The technical problems to be solved in the utility model is: propose the high electrolysis unit groove air outlet sealed structure of a kind of good seal performance and level of safety.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of electrolysis unit groove, the top of described unit groove has the air outlet, the oral area of described air outlet is provided with inner sleeve and outer sleeve, described inner sleeve outer wall is provided with outside screw, the inwall of described outer sleeve has the internal thread that matches with described outside screw, leaves annular recesses between described inner sleeve and described outer sleeve.
The beneficial effects of the utility model are:
The utility model will originally only be made into to be sealed by double layer sleeve barrel by the air outlet of individual layer sleeve seal by improving at traditional unit groove.Obtained preferably sealing property and improved security, having reduced the possibility of chlorine leakage.
Having improved of technique scheme:
In order better to coordinate the airtight construction of air outlet, a kind of gas fittings for joining with described air outlet is provided, the inwall of described joint is provided with the joint internal thread that matches with described outside screw, and described gas fittings outer wall is provided with the joint outside screw that matches with described internal thread.
In order better the air outlet to be sealed, be provided with sealing rubber ring in the silk groove of described outer, internal thread.
Description of drawings
Below in conjunction with accompanying drawing, a kind of electrolysis unit groove of the present utility model is described further.
Fig. 1 is the structural representation at place, electrolysis unit groove air outlet in the utility model.
Embodiment
Embodiment
According to shown in Figure 1, electrolysis unit groove top in the utility model has air outlet 1, the oral area of air outlet is provided with inner sleeve 2 and outer sleeve 3, inner sleeve 2 outer walls are provided with outside screw 4, the inwall of outer sleeve 2 has the internal thread 5 that matches with outside screw, leaves annular recesses between inner sleeve 2 and outer sleeve 3.
The utility model comprises that also inner nosepiece wall is provided with the joint internal thread that matches with outside screw for the gas fittings that joins with the air outlet, and the gas fittings outer wall is provided with the joint outside screw that matches with internal thread.Be provided with sealing rubber ring 6 in the silk groove of internal thread outward.
The above-described embodiment that is not limited to of the present utility model, all employings are equal to replaces the technical scheme that forms, and all drops in the protection domain of the utility model requirement.
