Description

The invention relates to evaporation electrode apparatuses intended for the concentration of electrically conductive solutions and suspensions - and may find application in the automotive, engineering, chemical and other industries.

The purpose of the invention is to increase the efficiency of work - due to the reduction of energy consumption,

Fig, 1 shows the apparatus, a longitudinal section ;. in fig, 2-- section aa in fig, 1; FIG. 3 is a section BB in FIG. 1; Fig, 4 - shelf, general view; FIG. 5 is a view B of FIG. 4; FIG. 6 is a section of the FIG. 5, FIG. 5;

The evaporating electrode apparatus comprises a housing 1, into which shelves 2 spaced apart along the height of the apparatus are inserted through the upper flap. Each shelf 2 is provided with electrodes 3, made in the form of parallel plates of sinusoidal shape. on the conductive substrate. The outer edge of the plates is rounded. One electrode is fixed inside the shelf 2, and the second - at its bottom. Between the electrodes 3 there is an electrical contact.

There is an alternating current in the electrode plates. The passage of current through the gutter holes 4 along the edges of the m. Shelves 2 with electrodes 3 are mounted on directional pins provided with insulating sleeves. The studs simultaneously have -j current leads, the electrical connection of the shelves is consistent. Only the lower electrode 3 is installed on the upper shelf 2, the electrodes around 1) are encased by blocks of incoming combs of plates

the thief is accompanied by heating and evaporation of the liquid. In zones of the maximal deviations of the plates, vertical circulation of the solution takes place, and between the control centers these zones are horizontal. These types of circulation occur against the background of rising bubbles. Gas and, steam, which cover all electrolyte mirrors. In the process of boiling sinusoidal form. Each plate 40 vapor and gas bubbles burst, the bottom electrode 3 is bent and the liquid is sprayed. Droplets of air 4 for the flow of fluid, Holes, a passage winding channel and stat 4 are located alternately at the edge of the upper innacTHH at the intersection of the electrode, flow back to the shelf, the longitudinal axis of symmetry of the sinus 45 Thus, the vapor phase, the output of the wells. Each shelf 2 is provided with an overflow from the electrode unit, separated by one tube 5 for the flow of liquid and then discharged through pipe 9, from the shelf to the shelf. Tube 5 has a pd. The solution through the holes 6 in the overflow tube 5 flows to the lower 50 shelf, Steam rising from the lower shelf through tubes 5 towards liquid holes 6 along the perimeter of the section at the level of the upper liquid edge on the shelf 2, Holes 6 are intended for uniform flow of liquid; from the shelf to the shelf ,

The housing 1 of the apparatus contains a pipe 7, located in the lid, for

entering the solution, the pipe 8 to exit one of the evaporated solution and the pipe 9 for removal of the vapor phase.

To ensure the longitudinal and transverse circulation of the electrolyte between the plates, the ratio between the distance of the upper electrode 3 to the bottom of the shelf a, the height of the electrodes b .. and the interelectrode distance is 1: 3: 2, for a: c 1: 2, the distance between the electrodes of the upper and lower comb is the same, which is important for current distribution. The ratio σ: s 3: 2 ensures, along with O, a uniform distribution of vapor bubbles on the surface, t, e, the uniform boiling of the entire volume of the solution.

Evaporator works as follows.

The solution to be evaporated is fed through the nozzle 7, which is located in the upper part of the housing 1, on the shelf 2. Through the bottom flows 4 in the plates 3 of the electrode unit, the solution fills the shelf and through the opening 6 in the overflow tube 5 first. Kata on the bottom and further to the next shelf apparatus. After filling all the shelves of the apparatus turn on the electric
