Problems solved by technology

[0009] 3. The adding flow is easy to fluctuate: the chlor-alkali industry generally sets the sodium sulfite preparation tank in the light brine dechlorination process. During each process of brine refining and membrane denitrification and transferring sodium sulfite solution, it is easy to cause fluctuations in the adding flow of light brine dechlorination, thus Causes chain switching of dechlorinated light brine containing free chlorine and membrane denitrification devices, which is not conducive to system stability

Embodiment Construction

[0027] The invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 and figure 2 As shown in the present invention, the chlor-alkali of the present invention is formulated with a sodium sulfite, including the formulation of the groove body 1 and the stirring mechanism 2, in the formulation slot body 1, the cavity is disposed, and a feed port 3 is provided on the formulation slot body 1, pure The water feed port 4 and the arrangement liquid outlet port 5 are provided on the formulation slot body 1, and the protective gas connection port 6 can be connected to the air supply line 8 and the protective gas supply device. Configure the protective gas in the cavity.

[0029] When the sodium sodium sodium sulfite solution is performed, the protective gas can be passed through the protective gas connection port 6 to the arrangement cavity in the formation of the groove body 1 to discharge the air in the cavity,...

Abstract

The invention discloses a sodium sulfite solution preparation tank for chlor-alkali and a preparation system, belonging to the technical field of preparation of sodium sulfite solution for chlor-alkali. In the present invention, after the protective gas connection port is set on the preparation tank body, the protective gas can be passed into the preparation tank body after being connected with the protective gas supply device, thereby reducing the oxidation of the sodium sulfite solution during the preparation process. Moreover, since the sodium sulfite solution in the configuration process will not be oxidized, the configured sodium sulfite solution can be directly stored in the configuration tank body without the need to separately set up a special storage tank structure, and it can be stored for a long time; therefore, since there is no storage tank structure, and can be stored for a long time, so the volume of the preparation tank body can be increased to reduce the frequency of preparation. At the same time, the main part of the entire preparation tank body can be installed below the ground to avoid manual transportation to high places and reduce labor intensity.

Description

Technical field [0001] The present invention relates to the field of formulation techniques for chline alkali solutions, and more particularly to a chlor-alkali solution formulation tank and a formulation system. Background technique [0002] The chlor-alkali industry saline system generally uses 10% sodium sulfite solution to remove free chlorine in salt water, and its use points are: [0003] A, Denslosis: Electrolytic Dichloro Dichloroe after EtOAc EtOAc [0004] B, one-time salt water: a salt water in front of the resin tower after salt water; [0005] C, membrane method of denithenia: brine pretreatment of membrane method. [0006] At present, most enterprises in the chlor-alkali industry use 97% of the bag industrial sodium sulfite, and add 10% sodium sulfite solution; the formulation tank used in which the formulation used is used in the arrangement of the upper formulation tank and the lower storage tank, intermediate connection catheter Connect; stirring into a sodium su...
