A forced circulation ion membrane electrolyzer

Abstract

The invention discloses a forced circulation ionic membrane electrolytic bath, and relates to electrolytic baths. The anode ionic membrane electrolytic bath internally comprises an inlet pipe, an anode frame chamber, a gas-liquid separation chamber and an outlet; the anode frame chamber is of a frame structure, a plurality of gratings are arranged on the frame structure, and divide the anode frame chamber into a plurality of unit chambers, a plurality of baffle plates are distributed in each unit chamber, and the baffle plates are distributed on the gratings at the two ends of the unit chambers in a left-and-right staggered manner; and due to the fact that the thickness of the ionic membrane electrolytic bath is small, when the ionic membrane electrolytic bath is applied to the chlor-alkali technology process, electrolytic process of the high current density can be achieved, and therefore the yield is increased; secondly, due to the baffle effect of the baffle plates, the height of the ionic membrane electrolytic bath can be reduced to 1 / 2 to 3 / 4 of the height of a traditional ionic membrane electrolytic bath, and the manufacturing cost of the electrolytic bath can be greatly saved; and finally the baffle plates which incline by a certain angle enable electrolytes flowing through the baffle plates to rotate in an orientation manner, the radial mixing degree is increased, and the raw material using rate is better improved.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to a forced circulation ion membrane electrolytic cell. Background technique [0002] Compared with the traditional mercury method or diaphragm method, the ionic membrane soda method has many advantages, such as low total energy consumption, no mercury or asbestos polluting the environment, and easy operation and control. Today's newly built chlor-alkali production facilities generally use the ion-exchange membrane method to make alkali, and some of the existing mercury-based or diaphragm-based chlor-alkali plants are also transformed into ion-exchange membrane methods while undergoing technological transformation. [0003] The ionic membrane electrolyzer uses a cation exchange membrane to separate the electrolytic cell into two parts, the anode frame chamber and the cathode frame chamber. Through the selective permeability of the cation membrane, the cation membrane allows positively charged...

Problems solved by technology

Due to the limited area of ​​the fluid flowing through the electrode network and membrane surface and the low current density of the traditional forced circulation mode electrolyzer, the output of the product is not large when the conversion rate is not high, which seriously affects the economic benefits
