Definitions
- the invention relates to housed pickling plants.
- pickling lines are, for example known from the Austrian utility models 2670 and 2671 and have in essentially proven.
- the invention aims to provide an apparatus and a method that this Does not have disadvantages and due to the relative humidity in the housing a value that is conducive to the pickling process can be maintained without being disproportionate Investments are made or large amounts of external energy are used have to.
- these goals are achieved in that the housing is preheated Air flow is supplied, and that the energy necessary for preheating at least mainly comes from waste heat.
- FIG. 3 A preferred variant of the invention is shown in FIG. 3. You use the fact that in the basement 4 of the housing 2, in which the individual pickling tanks 3 because of the high bath temperature, which keeps the air flowing is led through the basement, warms up accordingly.
- the hall air L0 is heated from 10 ° to 18 ° (air flow L1 ') and its relative Air humidity drops to 42%, so that even after crossing the housing 2 am Output as airflow L2 has a relative humidity of only 88% and thus also at Rush mode taking into account the irregularities that always occur during operation certainly below 100%, therefore always well above the dew point.
- FIG. 4 A particularly preferred variant is shown in Fig. 4, in which a second fan 8 is used, but particularly good results can be achieved.
- This variant turns indoor air L0 from rather cool areas of the hall at around 10 ° C sucked in by the fan 8, passed over the heat exchanger 7 and heated in the process and then blown back into hall 1 as air flow L0 '. Achieved in this way one in most areas of the hall a temperature of about 12 ° C, which is also the entrance temperature for the air flow L0 ", which is by means of the fan 5 through the basement 4 and so heated as L1 "denotes the housing 2 is pulled.
- the sink rate drops further relative humidity when entering the housing 2 and thus also a clear one Reduction of the humidity at the outlet of the air flow L2 from the housing 2, namely only 79%.
- the temperature raised to 33 ° C at this point makes the heat exchanger 7 more effective than he works in the previous examples, so here in terms of investment volume can be saved.
- the fan or the fan 5 has as in all other embodiments only with the assumed air volume of 40,000 kg per Hour (converted to dry air) and does not have to be more powerful than in the other examples.
- the temperature in is increased the hall, which is favorable for the working atmosphere and the greatest possible security against falling below the dew point in the housing 2, thus the main aim of the invention.
- the fans 5 and 8 By separating the fans 5 and 8, it is easily possible to always be to consider changing operating and environmental parameters again without it unpleasant feedback and side effects can occur here.
- the heat exchanger 7 is arranged in front of or behind the fans 5 and 8, respectively Expert in the field of flow and heat engineering with knowledge of the invention and easy to decide depending on the application.
- the over the balance limit (from the amount of air brought to Hall 1 to air washer 6) does not appear to be balanced since the Hall 1 in the drawing no air is supplied.
- This deficit amount becomes easy due to the various leaks of common factory halls in the roof area, in the window area and in the door and entrance area and of course through the ventilation of the Halle balanced himself and therefore not particularly shown in the figures.
- the fan 8 sucked air flow L0 is specified at a temperature of 10 ° C, while the general hall temperature (corresponding to L0 ") is specified at 12 ° C.
- L0 general hall temperature
- external energy primary energy
- the air washer does not necessarily have to be arranged outside the hall, although this is usually the case Case is. Even if it is set up inside the hall, its exhaust air is still outside performed, so that the position of the air washer has no influence on the invention Procedure.
- the fan 7 in the examples is arranged so that it is one in the housing Vacuum creates the release of pickling vapors from the housing (when opening the gates for introducing the pickling material etc.) to prevent. On the invention Of course, this has no influence on the process, it could also be carried out if the fan were placed in front of the enclosure. Any type can be used as a fan and the way it is common in pickling technology.
- waste heat in the description and the patent claims is primarily the Waste heat from the pickling process understood, but it is clear to the expert that each other waste heat at least in the hall in which the housed pickling plant is arranged is, either automatically in the course of the inventive method by the Sucking in the hall air is used or can be used by targeted suction can.
