Definitions

  • the invention relates to a method for direct heating of a liquid for wet treatment, preferably for washing, laundry according to the preamble of claim 1 or 5. Furthermore, the invention relates to a device for direct heating of a liquid for wet treatment, preferably for washing, laundry according to the preamble of claim 7 or 11.
  • Liquids for aftertreatment, in particular washing, of laundry items in commercial laundries are heated, inter alia, by means of steam.
  • steam With steam, relatively large quantities of liquids, such as those required in commercial laundries, can be heated up quickly.
  • the invention has for its object to provide a method and apparatus for direct heating of the wet treatment, in particular washing, used by laundry items by means of steam, which significantly reduce the noise without the supply of compressed air.
  • a method for achieving this object comprises the measures of claim 1. According to this method, it is provided to suck a subset of the liquid to be heated in the nozzle. It is sufficient to say only a relatively small portion of the liquid to be heated in the nozzle. By sucking in portions of the liquid into the nozzle, there is an effective mixing of the sucked liquid with the steam, preferably the steam accelerated in the nozzle, wherein a condensate-steam mixture is produced in the nozzle.
  • the condensate in the form of a very large number of heated water particles leads to effective reduction of noise during the introduction of the steam, which preferably flows at supersonic speed through the nozzle or is brought from the nozzle to supersonic speed. Also, the steam containing many heated water particles reduces vibration and vibration, which also contributes to noise reduction.
  • the subset of the liquid to be heated is sucked in from behind the narrowest cross section of the nozzle or sucked into the nozzle.
  • the cross-section of the steam flow is gradually increased, so the steam is relaxed.
  • a condensate / vapor mixture is produced particularly effectively behind the narrowest point of the nozzle, the resulting heated liquid particles being largely evenly distributed over the cross section of the vapor stream.
  • the introduction of the liquid to be heated behind the narrowest cross-section of the nozzle refers to the direction of flow of the steam through the nozzle, the term “behind” refers to the region of the nozzle which lies between the narrowest cross section thereof and the end of the nozzle, from which the steam comes out. If we speak of "before” the narrowest cross-section, that is the area of the nozzle meaning between the narrowest cross section and the beginning of the nozzle where the steam enters the nozzle. When used in the following "front” and “rear”, this is always based on the flow direction of the steam, even if this is not always mentioned for the sake of simplicity.
  • the method is provided to additionally suck in or suck in liquid by means of a mouthpiece following the nozzle.
  • the mouthpiece thus extends the nozzle by also the mouthpiece is flowed through by the steam.
  • the mouthpiece may be functionally considered to belong to the nozzle. Due to the additional suction of liquid to be heated in the mouthpiece a small subset of aufchristender liquid is mixed with the steam in the mouthpiece to increase the condensate-steam mixture with heated water parts.
  • This development of the method thus provides an extension of the distance along which the liquid to be heated is mixed with the steam flowing through the nozzle and the mouthpiece.
  • an annular gap a particularly effective and uniform suction or suction of the liquid to be heated is ensured in the nozzle or the mouthpiece, because in the annular gap or annulus around the nozzle and the mouthpiece from the high speed, preferably supersonic velocity, steam flowing through this, a negative pressure is produced.
  • Another method for the solution of the above-mentioned object comprises the measures of claim 5. Accordingly, it is provided to divide the emerging from the nozzle steam or a condensate-steam mixture.
  • the vapor stream or The condensate-vapor mixture stream are thereby divided into at least two, but optionally also several, partial streams.
  • the result is that only the smallest steam jets are ejected from the nozzle and / or an increase in the flow rate takes place. This surprisingly leads to a (further) reduction of the noise and / or vibrations or vibrations. This is especially true when the previously formed condensate vapor mixture is divided.
  • a further advantageous embodiment of the method provides that there is a division behind the nozzle.
  • the division is particularly effective after previously the condensate vapor mixture has been generated.
  • the nozzle on radially-directed through holes, preferably through holes, which may optionally be formed like a nozzle, on.
  • the through-holes and through-holes preferably provide connection of the annulus at least partially surrounding the nozzle to an inner nozzle bore in the nozzle.
  • liquids to be heated from the outside through the passage openings or through bores can be supplied to the nozzle bore by being sucked out of the annular space as the nozzle bore flows through steam through the passage openings or through bores.
  • the at least one liquid to be heated is sucked into the nozzle bore and mixed in this with the steam to form a condensate-steam mixture of many heated water parts. Due to the high flow rate, preferably supersonic velocity, of the vapor through the nozzle, the liquid is effectively and uniformly mixed with the vapor.
  • the device is further developed in such a way that the through-openings are arranged in a rear region of the wall of the nozzle following the narrowest cross-section of the nozzle bore.
  • the mixing of the steam with liquid to be heated is thereby effected after the maximum acceleration of the steam in the nozzle, preferably when the flow rate of the steam behind the narrowest cross section of the nozzle bore decreases again and the steam is released.
  • This ensures a particularly effective and uniform mixing of the steam with the liquid to be heated.
  • the preferably as through-holes, possibly also formed as nozzles through holes are further preferably distributed uniformly over the wall of the rear portion of the nozzle, namely optionally in several successive rings in the flow direction of the steam through the nozzle. As a result, the steam is mixed with liquid to be heated over a longer distance.
  • the device provides to arrange behind a downstream end of the nozzle, a preferably cylindrical mouthpiece.
  • the mouthpiece is also provided with radially-directed through holes or through-holes, which are advantageously distributed uniformly over the cylindrical circumference of the mouthpiece.
  • the through-holes or through-holes which may also be nozzles, are distributed uniformly in the circumferential direction and over the entire length of the cylindrical shell of the mouthpiece to form a uniform grid of through-holes or through-holes in the mouthpiece.
  • the annular space between the mixing tube and the mouthpiece is further preferably provided to continue in the region of the mouthpiece the annular space between the mixing tube and the mouthpiece and alternatively or additionally to provide the mouthpiece with such a cylindrical inner diameter, which corresponds approximately to the circular cross-section of the nozzle bore at the exit-side rear end of the nozzle.
  • the annular space extending also in the area of the mixing tube, the vapor flowing through the mouthpiece at high speed can generate a negative pressure in the annular space, whereby liquid to be effectively heated can be sucked in small quantities from the annular space into the mouthpiece from the steam flowing through it at high speed.
  • the steam flows through the mouthpiece at the same rate as exiting the nozzle, which also effectively draws liquid to be heated from the annulus and an effective mixture the liquid sucked into the mouthpiece is caused by the vapor.
  • At least one flow divider is provided in the flow direction of the steam through the nozzle.
  • the flow divider brings about a cross-sectional constriction in the mouthpiece or mixing tube, which contributes to an increase in the flow velocity and leads to rapidly flowing partial streams which atomize the aspirated liquid into a large number of very fine particles, as a result of which the proportion of condensate in the condensate / vapor mixture greatly increases.
  • At least one flow divider is assigned to a steam outlet-side, rear end region of the mixing tube.
  • it may be provided to provide at least one flow divider at the rear in the mouthpiece.
  • the at least one flow divider it is possible to divide the vapor condensate mixture in the rear end region of the device, possibly several times. The division takes place before or just before the steam condensate mixture is supplied to the majority of the liquid to be heated. As a result, a noise on impact of the condensate vapor mixture is significantly reduced to the liquid still to be heated, without throttling the steam supply would be required.
  • An advantageous embodiment of the device provides for the at least one flow divider to be designed as an installation, preferably a plate-like installation, extending diametrically through the end region of the mixing tube or the mouthpiece.
  • this plate-like installation in the flow direction of the steam or the vapor condensate mixture can be widened by the mouthpiece or the subsequent rear part of the mixing tube. This contributes to increasing the flow rate of the vapor condensate mixture leaving the mixing tube or the mouthpiece and to the finer atomization of the condensate in the vapor as well as a significant increase of the condensate fraction in the vapor.
