The design of a ﬂ at-chamber–type eleсtrobaromembranе apparatus and, based on the design, a method of
calculating the parameters of the housing chamber when it is subjected to excess pressure are developed.
Through the use of the technique, it becomes possible to determine the total force on a thin wall, the force
per node of the sieve, the total number of nodes in the sieve, the maximum contact stresses for the material
with contact of the sieve at the nodes, and the convergence of the axes of contacting surfaces.
Keywords: design, eleсtrobaromembranе apparatus, calculation, membrane, solution, separation.
A search for ways of improving the technological and structural designs is needed in view of the intensive develop-
ment of membrane methods of separation of solutions in the chemical, petrochemical, and food branches of industry.
Well-known apparatuses for performing processes of electromembrane separation of solutions do not assure the re-
quired efﬁ ciency and degree of separation [1–4].
In the present article, we present a construction of a ﬂ at-chamber apparatus that realizes these objectives (Fig. 1). The
problem of calculating the strength of certain parts of the apparatus on the basis of its structural features and brand of selected
material (caprolan) is a critical problem.
A single-chamber apparatus consisting of a porous anode and porous cathode, near-anode and near-cathode mem-
branes, and housing was selected as an analog . The drawbacks of the apparatus include the small separation area and high
energy costs of the separation process. These drawbacks are partially eliminated in the construction of the apparatus .
The strength calculations of apparatuses belonging to this class that have been performed up to now [7, 8] were de-
signed to study the stress-strain state of the most loaded extreme ﬂ anges of a ﬂ at-chamber apparatus without considering the
alternating dielectric chambers of the housing of the apparatus, since these chambers are usually under the same levels of
pressure. Because of the structural features of the new apparatus, equilibrium breaks down under the effect of the excess
pressure on the walls of the dielectric chambers of the housing, particularly at the site of the chamber used for discharge of
the transport agent.
The following construction of a dielectric chamber of the housing with a “recess” (Fig. 2) is proposed here and a
technique of calculating the parameters of such chambers developed.
In view of the low degree of thickness of the wall separating the high-pressure chamber and the chamber through
which the transport agent is discharged (cf. Fig. 2), complete coverage of the wall of the chamber through which the transport
agent is discharged is achieved as a result of deformation of the wall. Therefore, a drainage sieve is provided in the discharge
chamber to assure free passage of the transport agent through the discharge channel. However, in view of the high contact
