Abstract
Inventia se refera la un schimbator de caaldura tubular, constituit dintr-o carcasa în forma de "U" în care sînt montate niste tevi de schimb termic, destinat încalzirii unor solutii în special a celor folosite la extractia bauxitei prin lesie sodica. Schimbatorul de caldura tubular, este prevazut cu o teava continua prin care circula mediul lichid supus încalzirii si care este trecuta de mai multe ori, în spirala prin interiorul uneia sau a doua carcase în forma de U, în care se introduce un agent încalzitor, numita teva continua aflîndu-se partial încalzita, în cazul folosirii unei singure carcase în forma de U sau total în cazul folosirii a doua carcase si avînd segmentele situate într-o parte si în cealalta asamblate între ele etans fie individual cu niste flanse de legaturi, fie global cu doua perechi de flanse de colectare.The invention relates to a tubular heat exchanger consisting of a U-shaped housing in which heat exchanging tubes are provided for heating some solutions especially those used for the extraction of bauxite by sodium lysate. The tubular heat exchanger is provided with a continuous pipe through which the liquid medium subjected to heating circulates and which is passed several times in the spiral through the interior of one or two U-shaped casings in which a heating agent the continuous pipe is partially heated, in the case of the use of a single U-shaped case or totally in the case of the use of two carcasses and having the segments located on one side and the other assembled together either individually with some flanges of links or with two pairs of collecting flanges.
