Definitions
- the invention relates to a furnace for the fusion of inorganic salts.
- furnaces for the fusion of inorganic salts are known in the state of the art. All these furnaces are characterized by being formed by a vessel that is kept warm by means of heating elements, an inlet means for feeding the furnace of inorganic salts in solid state and an outlet means (for example an overflow) to extract the salts inorganic molten.
- the inorganic salts melted by these ovens can subsequently be used for various uses.
- the melting furnaces of inorganic salts usually comprise in their interior some means to remove the inorganic salts in fusion process and thus homogenize the temperature of the salts inside. Physical separation elements are also sometimes found between the solid salt inlet medium and the molten salt outlet medium, to prevent solid salts (of less apparent specific weight) from floating out over the molten ones by the outlet means.
- inorganic salt melting furnace comprises a container of a relatively complex shape with burners that melt the upper area of the salts contained therein.
- a recirculation unit removes the salts to facilitate the homogenization of them and their extraction through an exit zone.
- Said furnace comprises a container of substantially vertical arrangement, heat exchange tubes, through which the flame of burners circulates, an inlet zone of solid salts and a unit of extraction of molten salts.
- the oven comprises a circulation unit that creates a flow of molten salts inside the container. Said flow, the document affirms, creates two zones, one of solid salts and another of molten salts, being from this supposed second zone from which the extraction unit extracts molten salts.
- the heat exchanger tubes of the furnace in question are close to the walls of the container, presenting a vertical coil shape, doubly descending and ascending, with gas outlet in its highest part to a collector in the upper part of the oven.
- said vertical heat exchanger tubes can overheat due to lack of salt level in the oven. Therefore, the heating of this type of furnaces must be carried out at all times with the furnace completely filled with salts, to avoid deterioration of the tubes.
- the volume of the salts when melted is reduced by approximately 50% leaving the heat exchange tubes constantly exposed.
- the present invention aims to manufacture a melting furnace of inorganic salts that eliminates the aforementioned risks, thereby improving safety.
- the furnace of the invention seeks to increase performance, as well as improve the working conditions of the operators.
- the object of the invention is an inorganic salt melting furnace, comprising a vessel, at least one solid inorganic salts inlet zone and at least one molten inorganic salts outlet zone.
- the oven according to the invention comprises at least one heat exchanger tube (also known as a coil) characterized by being provided with an inlet area connected to the outer side wall of the container, a spiral body substantially along the internal walls of the container, delimiting an interior space and a section of substantially vertical exit descending towards the base or ascending towards the upper part of the container.
- the spiral body of the heat exchanger tube is arranged in a substantially horizontal plane.
- a burner is connected to the inlet zone of the heat exchanger tube, not being relevant to the present invention.
- the oven comprises several tubes heat exchangers of the type described, installed at different heights and defining different levels of heating. This allows, during the start-up of the furnace, that is, during the initial filling of the furnace, the solid salts can be heated in ascending order in height, starting with the heat exchanger tube located lower and reaching the top. This eliminates the risk of explosion of the furnace since the gases generated can evacuate freely by not having on them a layer of salts in solid state.
- the heating of the salts will be carried out in the opposite direction, that is, the heating being started in descending order, starting with the highest heat exchanger tube, to continue, once the salts of its level are melted, by the second tube and so on until it reaches the last tube of the lower part.
- the risk of explosion is avoided, since above the zone that is being heated there are no salts in solid state, allowing the evacuation of the gases that are generated during the heating through the molten salts as a bubble , finally evacuating a gas outlet.
- Figure 1 shows a perspective of the preferred embodiment of the oven according to the invention.
- Figure 2 shows an elevation of the oven of Figure 1.
- Figure 3 shows a plan view of the oven of Figure 1.
- Figure 4 shows a perspective of a heat exchanger tube according to the invention.
- FIG. 5 shows an elevation of the heat exchanger tube of Figure 4.
- FIG. 6 shows a plan view of the heat exchanger tube of Figure 4.
- Figure 7 shows a sectional view of the oven according to the sectional plane AA of Figure 2.
- Figure 8 shows a sectional view of the furnace according to section plane BB of Figure 2.
- FIG 1 shows a perspective of the preferred embodiment of the oven according to the invention.
- the oven comprises a container (1), which in the present embodiment has a cylindrical shape.
- the oven comprises an inlet zone (2) of solid inorganic salts, where the crushed and mixed solid inorganic salts are introduced.
- the oven comprises an outlet zone (3) of molten inorganic salts, which in the present embodiment has the form of overflow.
- Figures 2 and 3 show, respectively, an elevation and a plan view of the furnace of Figure 1.
- the furnace comprises a series of heat exchange tubes or internal coils, which conduct combustion gases at a very high temperature inside, causing heating and melting of inorganic salts.
- the heat of the heat exchanger tubes is generated by burners (4) located outside the container, one for each heat exchanger tube (5). These burners can be seen in Figures 1, 2, 3 and 7.
- FIGS. 4 to 6 show three views of one of the heat exchange tubes (5) according to the invention.
- Each heat exchanger tube (5) comprises an inlet section (5a), a spiral section (5b) and an outlet section (5c).
- the inlet section (5a) is connected to the outer side wall of the container (1), the corresponding burner (4) being mounted externally. In said inlet section (5a) combustion begins, the same acting as home.
- the spiral section (5b) extends substantially along the inner side walls of the container (1) delimiting an interior space (6), and is arranged on a substantially horizontal plane.
- the spiral shape is very relevant since it allows dilation in all directions, preventing the heat exchanger tube (5) from supporting mechanical stresses and deformations as a result of the aforementioned dilations, increasing the life of the heat exchange tubes (5 ) in the absence of mechanical fatigue.
- the exit section (5c), in the present embodiment descends substantially vertically towards the base of the container (1), in this case reaching said base.
- exit section (5c) may be directed towards the upper part of the container (1) (for example towards an upper cover (14) covering it).
- the exit section (5c) preferably extends to the base or the upper part of the container (1), although different alternatives are not ruled out. Especially advantageously, as shown in Figures 7 and
- the furnace comprises several heat exchange tubes (5), in this case a total of eight, arranged at different heights, defining different levels of heating of the container (1) and being able to arrange or not each level of a system of independent temperature control. This allows the salts to be melted by levels, when the fusion begins, significantly improving safety.
- the start-up procedure is as follows: - First, solid salts are provided to cover the first heating level of the container (1) (which corresponds to the lower heat exchanger tube (5)). The corresponding burner (4) is ignited, the heat exchanger tube being heated and the salts melted in contact with it, until a molten salt bed is formed in the lower part of the container (1). This heating process is not possible in an oven with vertical heat exchanger tubes, since most of these would remain in the air, out of contact with the salts, and with the consequent risk of overheating. - Subsequently, solid salts continue to be added until a second level of heating of the container (1), corresponding to the second heat exchanger tube (5), in an upward direction.
- this second level of salts melts. - This process is repeated with the successive heating levels of the container (1). Once all the burners (4) are lit and the temperature necessary to melt and pump the salts (approximately 150 ° C higher than the melting temperature of these) has been achieved, salts continue to be added up to the level of the outlet zone (3). That is when the oven is able to supply molten salts. From that moment on, with the addition of new solid salts, molten salts are exited through the outlet zone (3) or overflow, to a post-fusion tank, not shown in the figures.
- a stirring system for example mechanical or induction
- a mechanical rotary stirrer (8) having been represented in this case to achieve uniform temperatures at all levels of the container (1) and increase heat transmission between heat exchange tubes (5) and molten salts.
- the stirring system causes the spinning of the molten salts to countercurrent, that is, in the opposite direction to the rotation of the combustion gases inside the spiral section (5b) of the heat exchanger tubes (5). This allows to increase the performance and heat transmission of the heat exchange tubes (5), achieving a higher production of molten salts with lower energy consumption.
- the oven being in these conditions, by providing solid salts on top of the molten salts, the former melts instantly, being dragged by the rotation of the downward vertical cyclone generated by the stirring system to the bottom of the container (1), returning perimetrically to the surface with upward rotation between the radiant heat exchanger tubes (5), which overheat them again at the temperatures set by the control and safety systems of each zone if they are installed. Said overheating allows to melt the new solid salts that are continuously added at the top.
- the furnace according to the invention preferably comprises a gas collection cavity (9) located in the lower part or in the upper part of the container (1), depending on where the outflow sections (5c) of the heat exchanger tubes are displaced. heat (5).
- the outlet sections (5c) of each heat exchanger tube (5) expel or evacuate their combustion gases into said cavity (9).
- the figures show a cavity (9) located in the lower part of the container (1).
- the cavity (9) provides the residual heat of combustion to the container (1).
- the cavity (9) preferably communicates with an underground duct (10) underground, which is used as an outlet for the flue gases, as shown in Figures 1 and 2.
- Said lower duct ( 10) continue in a chimney (1 1) separated from the oven. This improves the safety and working conditions of the furnace operators, by moving the chimney away from the work area.
- the cavity (9) is located in the upper part of the container (1), similarly the gases can be extracted from said cavity (9) outwards by a duct that ends in a chimney.
- the oven can also comprise at least one safety overflow (12), which is used in case of additional need. It can also comprise an internal dividing element (13) to separate the solid salts that are introduced through the inlet zone (2) and which float on the molten salts, thus preventing the exit of solid salts from the outlet zone (3) and cushioning the possible level differences generated by the agitation system.
- the heat exchanger tubes (5), the container (1) (including an upper lid (14) covering the same) and / or the gas collecting cavity (9) are partly made of stainless steel and partly of steel to carbon
