Definitions
- the present invention relates to a steam generator with an evaporation vessel and at least one heating element.
- Steam generators are used, for example, for air humidification and usually comprise an evaporation vessel that is partially filled with water.
- the water is heated with radiators, e.g. Electrodes or electrical resistors, heated and evaporated, precipitating mineral salts that must be removed from the evaporation vessel from time to time by blowdown.
- radiators e.g. Electrodes or electrical resistors, heated and evaporated, precipitating mineral salts that must be removed from the evaporation vessel from time to time by blowdown.
- the latter has at least one water passage opening, which is often arranged in its bottom.
- a steam generator is to be created with an evaporation vessel with at least one water passage opening which does not calcify or at least calcifies more slowly than the water passage openings of the previous steam generators.
- the evaporation vessel is at least partially double-walled with an inner wall and an outer wall that delimit an outer chamber.
- the inner wall has at least one inner water passage opening connecting the inside of the vessel with the outer chamber and the outer wall has at least one outer water passage opening, so that the water supply into the inside of the vessel and the water withdrawal from the inside of the vessel via or at least one of the outer water passage openings, the outer chamber and the or at least one of the inner water through openings.
- the inner or inner water passage openings which are exposed to the lime-discharging hot water from the inside of the vessel, can be chosen to be relatively large, so that they do not grow too quickly.
- the evaporation vessel comprises an evaporation container, which has an opening at the bottom, and an interchangeable lime receptacle arranged below it with a filling opening, so that lime which has separated out inside the evaporation container passes through the evaporation container opening and the filling opening into the lime reception container.
- the interior of the evaporation container is not filled with lime and the lime that has separated out has to be removed less quickly. Lime removal is also easier, especially if the lime container is replaced or emptied before it is completely filled with lime.
- the double-walled part of the evaporation vessel can either be on the evaporation container or on the lime receptacle. ter or both.
- An approximately horizontal or outwardly inclined limescale surface is advantageously arranged in the outer chamber, which can be formed in particular by the inside of a part of the outer wall.
- This limescale deposit traps limescale that flows through the at least one inner water passage opening into the outer chamber, and the lime released in the outer chamber itself before the outer water passage opening (s).
- Fig. 1 - a schematic, partially sectioned view of a steam generator according to the invention
- Fig. 2 is a partially sectioned perspective view of part of the steam generator of Fig. 1;
- Fig. 3 is a partially sectioned perspective view of an insulating insert of the steam generator of Fig. 1;
- FIG. 4 shows a partial view of a steam generator according to the invention similar to FIG. 1, but with an additional insulating part;
- FIG. 5 is a perspective view of an insulating part of the steam generator of FIG. 4.
- the steam generator shown comprises an evaporation Barrel with an evaporation container 1 and a lime receptacle 4.
- the evaporation container 1 has a lid 15, to which a plurality of radiators 2, for example resistance heating elements, projecting into the interior of the vessel, are attached, here the. For the sake of clarity, only one is drawn.
- the evaporation container 1 is filled to about two thirds with water, the water level 10 not being homogeneous due to the boiling water during operation.
- the steam generated is discharged via a steam line 6.
- the evaporation container 1 is double-walled with an inner wall 11 and an outer wall 12, which delimit an outer chamber 13, and has an opening 14 at the bottom.
- the outer wall 12 is essentially cylindrical with a shoulder forming a horizontal limescale settling surface 123.
- the upper part of the inner wall 11 is also cylindrical, while the lower part is funnel-shaped, so that lime which has separated out and is blasted off from the inner wall 11 or the radiators 2 slides off.
- the distance between the inner wall 11 and the outer wall 12 is approximately 10 mm in the upper part and is ensured by bulges 113 and an outwardly bent upper edge 114 of the inner wall 11.
- the limescale surface 123 extends up to the inner wall 11, the latter having two indentations 112, which allow water to pass through between the edge of the limescale surface 123 and it.
- the outer chamber 13 is continuous around the inner wall 11.
- the interior of the evaporation vessel is connected to the outer chamber 13 via four inner water passage openings 111 in the inner wall 11.
- the inner water outlet openings 111 have a diameter of approx. 30 mm and therefore do not grow too quickly.
- the outer water passage openings 121, 122 have a diameter of approximately 20 mm, so that on the one hand any pieces of lime entrained in the draining can be washed out, but on the other hand there is no risk that the water in the evaporation vessel will start to oscillate after the draining.
- This insulating insert 3 insulates the outer chamber 13 in the region of the lime deposits setting surface 123 and the outer Wasser mallasso réelleen 121, 122 against the thermally Geutzinnere and ensures that the water temperature is less than 50 C C in this area.
- the insulating insert 3 shown is designed for this purpose as a waterproof blow-molded part with an air-filled cavity 31, but could also be a waterproof, welded, multi-part plastic injection-molded part with a cavity, a waterproof, welded, multi-part metal part with a cavity, a thick-walled part, in particular made of elastomer , or a plastic injection molded part with gaseous inclusions, in particular air inclusions, or consist of a foam-like material.
- the outer wall 12 comprises, below the limescale settling surface 123, a connecting piece 124 which is firmly connected to the rest of the outer wall 12, an annular seal 125 ensuring the tightness.
- the interchangeable lime receptacle 4 with filling opening 41 is arranged on the connecting piece 124, in which the lime which has separated out in the evaporation container 1 and is blasted off from the inner wall 11 or the radiators 2 collects.
- the lime receptacle 4 has two cams 42 which are suspended in two holes of two holding parts 51 extending from a platform 5 for its fastening.
- a water addition and removal device 7 is connected to the water passage opening 121 and a water level monitoring device 8 is connected to the water passage opening 122.
- the water level monitoring device 8 comprises a water line 81 leading from the outer water passage opening 122 to a float housing 82 and a pressure compensation line 84 leading from the float housing 82 to the steam line ⁇ .
- a float 83 is arranged in the float housing 82, which indicates the level of the water level 10, which in the float housing 82 and in the evaporation vessel is the same, since the interior of the float housing 82 is connected to the interior of the evaporation vessel via the water line 81, the outer water passage opening 122, the outer chamber 13 and the inner water passage openings 111.
- the float position can be recorded electronically and used to control the water level 10.
- the water addition and removal device 7 comprises a water line 71 leading from the outer water passage opening 121 to an inlet cup 73 open at the top, in which a pump 72 is arranged, with which water flows through the outer water passage opening 121, the outer chamber 13 and the inner water passage openings 111 can be pumped out inside the vessel.
- a water supply line 74 with a valve 75 leads to the inlet cup 73 and a water outlet line 76 away from the inlet cup 73.
- the steam generator shown in FIG. 4 is constructed similarly to that shown in FIG. 1, but has an insulating part 9 for the thermal insulation of the outer chamber 13 towards the inside of the vessel between the inner wall 11 and the outer wall 12 per inner water passage opening 111.
- the insulating parts 9 each extend from the relevant inner water passage opening 111 down to a little below the height of the upper edge of the funnel-shaped iso- 3. They insulate the outer chamber 13 above the limescale surface 123 thermally against the interior of the vessel.
- the insulating part 9 shown is designed for this purpose as a waterproof blow-molded part with an air-filled cavity 91, but could also be a waterproof, welded, multi-part plastic injection-molded part with a cavity, a waterproof, welded, multi-part metal part with a cavity, a thick-walled part, in particular made of elastomer , or a plastic injection molded part with gaseous inclusions, in particular air inclusions, or consist of a foam-like material. It has an anchoring part 92 which extends into the relevant inner water passage opening 111 and a jacket part 93 which is bent in accordance with the inner wall 11.
- the inner wall 11 can also be made better insulating in the desired area, for example by including a cavity, thick-walled design and / or using a suitable material.
- the outer water passage openings 121, 122 can be arranged in the area of the latter instead of below the lime sedimentation surface 123.
- a single insulating part extending around the inner wall 11 can be provided.
