Abstract

The mounting devices for compact submerged tubes in a tank containing a liquid comprise a watertight casing (4) in which the burner head (3) is installed at a level lower than the bath surface by tubes (7,8) located above the bath level. There is a premixing and control case (5) for the heating equipment located outside the tank.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne deux dispositifs de montage de tubes immergés compacts sur cuves garantissant l'étanchéité de l'équipement de chauffe et le maintien du liquide dans la cuve en cas de percement de l'échangeur situé dans cette même cuve. The present invention relates to two devices for mounting compact submerged tubes on tanks guaranteeing the tightness of the heating equipment and maintaining the liquid in the tank in the event of the exchanger being located in this same tank.

Dans l'industrie des traitements de surfaces, beaucoup de techniques chimiques et électrolytiques impliquent l'utilisation de cuves (1) remplies de bains acides ou basiques. Ces produits, outre qu'ils sont onéreux, sont généralement hautement corrosifs, d'où le maximum de précautions pris lors de leur emploi.  In the surface treatment industry, many chemical and electrolytic techniques involve the use of tanks (1) filled with acidic or basic baths. These products, in addition to being expensive, are generally highly corrosive, hence the maximum precautions taken during their use.

Les systèmes de chauffe actuels de ces bains se composent d'un échangeur de chaleur installé dans la cuve en traversée de paroi en dessous de la surface du bain. Si cet échangeur vient à percer, tout ou partie du bain se vide à l'extérieur de la cuve par l'une des extrémités de cet échangeur, avec parfois des conséquences graves en termes de sécurité des opérateurs et de respect de l'environnement.  The current heating systems of these baths consist of a heat exchanger installed in the tank through the wall below the surface of the bath. If this exchanger comes to pierce, all or part of the bath is emptied outside the tank through one of the ends of this exchanger, with sometimes serious consequences in terms of operator safety and respect for the environment.

De plus l'article 5.5 de l'arrêté du 26 septembre 1985 relatif aux ateliers de traitement de surfaces précise que'le circuit de régulation thermique ne comprendra pas de circuits ouverts'.  In addition, article 5.5 of the decree of September 26, 1985 relating to surface treatment workshops specifies that 'the thermal regulation circuit will not include open circuits'.

Les dispositifs selon l'invention permettent de remédier à cet inconvénient et de se mettre en conformité avec l'arrêté ci-dessus.  The devices according to the invention make it possible to remedy this drawback and to comply with the above decree.

Ils comportent l'installation de la tête du brûleur (3) dans un caisson étanche dénommé'puits' (4) implanté en partie supérieure de la cuve, légèrement immergé, selon la technique dite'en puits'ou'en plafonnier', de sorte que le liquide reste dans l'échangeur (2) et le puits (4) en cas de percement de l'échangeur.  They include the installation of the burner head (3) in a sealed box called 'well' (4) located in the upper part of the tank, slightly submerged, according to the so-called 'well' or 'ceiling' technique, so that the liquid remains in the exchanger (2) and the well (4) if the exchanger pierces.

La liaison entre la tête du brûleur (3) et le caisson de prémélange et de commande (5) de l'équipement de chauffe, situé lui hors de la cuve (1), peut s'effectuer selon deux modes d'installation différents :
Solution 1 : soit en traversée de cuve étanche au dessus du niveau du bain (planche 1/2)
Solution 2 : soit par dessus le bord de la cuve (planche 2/2) The connection between the burner head (3) and the pre-mixing and control box (5) of the heating equipment, which is located outside the tank (1), can be carried out according to two different installation methods:
Solution 1: either by crossing a sealed tank above the bath level (board 1/2)
Solution 2: either over the edge of the tank (board 2/2)

Les dessins annexés illustrent l'invention :
La figure 2 représente en coupe le dispositif de l'invention en traversée de cuve. The accompanying drawings illustrate the invention:
Figure 2 shows in section the device of the invention through the tank.

La figure 4 représente en coupe le dispositif de l'invention par dessus le bord de cuve.  Figure 4 shows in section the device of the invention over the edge of the tank.

L'assemblage du puits (4) avec le corps de chauffe (6) sera réalisé : - dans la solution 1 (figure 2) par vis et joint d'étanchéité.  The assembly of the well (4) with the heating body (6) will be carried out: - in solution 1 (figure 2) by screw and gasket.

- dans la solution 2 (figure 4) par soudures étanches.  - in solution 2 (Figure 4) by tight welds.

Dans le cas de la liaison entre la tête du brûleur (3) et le caisson de prémélange et de commande (5) en traversée de cuve (fig. 2), l'étanchéité de la liaison sera assurée par soudure ou par joint d'étanchéité.  In the case of the connection between the burner head (3) and the premix and control box (5) through the tank (fig. 2), the connection will be sealed by welding or by gasket. seal.

Selon une variante non illustrée, concernant les figures 1 et 2, l'arrivée du prémélange air/combustible du brûleur d'allumage (7) peut s'effectuer au dessus de ou sur le même plan que l'arrivée du prémélange air/combustible du brûleur principal (8).  According to a variant not illustrated, concerning FIGS. 1 and 2, the arrival of the air / fuel premix of the ignition burner (7) can take place above or on the same plane as the arrival of the air / fuel premix of the main burner (8).

Par ailleurs la cuve (1) et le puits (4) étanche recevant la tête du brûleur (3) peuvent être fabriqués en diverses matières telles qu'acier au carbone, acier inoxydable, matériaux composites, cette liste n'étant pas limitative.  Furthermore, the tank (1) and the sealed well (4) receiving the burner head (3) can be made of various materials such as carbon steel, stainless steel, composite materials, this list not being limiting.

La forme de l'échangeur (2) ainsi que la position de l'évacuation des produits de combustion (9) représentés sur les figures 1 et 2 ne sont qu'indicatives. Ce projet ne limite pas la forme de l'échangeur (2) ni les positions d'évacuation des produits de combustion (9), cette dernière s'effectuant dans tous les cas au dessus du niveau du bain.  The shape of the exchanger (2) and the position of the evacuation of the combustion products (9) shown in Figures 1 and 2 are only indicative. This project does not limit the shape of the exchanger (2) or the combustion product discharge positions (9), the latter being carried out in all cases above the level of the bath.

La liaison entre la tête du brûleur et le caisson de prémélange et de commande de l'équipement de chauffe peut s'effectuer soit par un (des) tube (s) rigide (s) soit par un (des) tube (s) flexible (s). The connection between the burner head and the pre-mixing and heating equipment control box can be made either by one (s) rigid tube (s) or by one (s) flexible tube (s) (s).
