  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a steam collecting device according to the present invention, and FIG. 2 is a perspective view showing an internal structure.

  In the figure, the steam collecting device 10 includes a casing 12 having a rectangular parallelepiped shape, and a steam inlet 14, a water inlet 16, and an outlet 18 provided on the outer surface of the casing 12. The steam inlet 14 and the water inlet 16 are provided on the side surface of the housing 12, and the outlet 18 is provided on the lower surface of the housing. The steam inlet 14, the water inlet 16 and the outlet 18 can be detachably connected to a hose or the like. The housing 12 is made of, for example, metal and can be composed of a plurality of parts, and the shape thereof can also be an arbitrary shape.

  A plate heat exchanger 20 is provided in the housing 12. As shown in FIGS. 3 and 4, the plate heat exchanger 20 is configured by stacking a plurality of high heat transfer plates made of stainless steel or the like between a front plate 22 and a rear plate 24. . The plurality of heat transfer plates include two kinds of first heat transfer plates 34 and second heat transfer plates 36, which are alternately stacked. In the heat transfer plates 34 and 36, groove-shaped flow paths 34a and 36a through which steam or low-temperature fluid flows are formed.

  Openings 26, 28, 30, and 32 are provided at the four corners of the front plate 22, and the openings 26, 28, 30, and 32 are formed through the heat transfer plates.

  The first flow path 34a of the first heat transfer plate 34 communicates with the first inlet 26, which is one of the openings, at its upper end, and communicates with the first outlet 28, which is one of the openings, with its lower end. On the other hand, the other openings 30 and 32 are water-tightly separated from each other by a sealing member.

  The second flow path 36a of the second heat transfer plate 36 communicates with the second outlet 30 that is one of the openings at its upper end, and communicates with the second inlet 32 that is one of the openings with its lower end. On the other hand, the other openings 26 and 28 are separated from each other by a sealing member in a watertight manner.

  Further, the adjacent first heat transfer plate 34 and the second heat transfer plate 36 are separated in a watertight manner through a seal member and overlap each other.

  The first inlet 26 is connected to the steam inlet 14 by a pipe 40, the second inlet 32 is connected to the water inlet 16 by a pipe 42, and the first outlet 28 and the second outlet 30 are connected to a pipe 44. And are connected to the outlet 18.

  Further, a pipe 46 is fixed to the housing 12, and the pipe 46 includes a hook portion 46 a bent in a curved shape on the upper side of the housing 12 and a leg portion 46 b below the housing 12. And form.

  The housing 12 may be filled with a heat insulating material such as glass wool.

  In the steam collecting apparatus 10 configured as described above, the steam collecting apparatus 10 is appropriately arranged in a work place having a steam generation source, and is connected to the steam inlet 14 by a connecting member such as a hose. Further, the water supply source is connected to the water inlet 16 by a connecting member such as a hose.

  After the connection, the steam from the steam generation source is introduced into the first inlet 26 of the plate heat exchanger 20 through the steam inlet 14 and the pipe 40. Further, it flows downward from the first inlet 26 to the first outlet 28 through the flow path 34 a of the first heat transfer plate 34.

  On the other hand, water from the water supply source is introduced into the second inlet 32 of the plate heat exchanger 20 through the water inlet 16 and the pipe 42. Further, it flows upward from the second inlet 32 to the second outlet 30 through the flow path 36 a of the second heat transfer plate 36.

  In this way, when the steam flows through the flow path 34a of the heat transfer plate 34, heat is exchanged with water through the heat transfer plate and is converted into hot water. Further, when water flows through the flow path 36 a of the heat transfer plate 36, it is converted into hot water. These hot water flows out from the outlet 18 via the first outlet 28, the second outlet 30, and the pipe 44. The warm water flowing out from the outlet 18 can be appropriately used for any other application via a connecting member connected to the outlet 18.

  Thus, by collecting the steam by the steam collecting device 10 and changing it to warm water, it is possible to prevent the steam from deteriorating the environment of the workplace. Therefore, an increase in discomfort index due to an increase in temperature and humidity in the work space can be suppressed. In addition, since the load on the air conditioning system can be reduced, the electricity bill can be reduced.

  By using the plate heat exchanger 20, it can be configured in a small size. Further, since the steam and water are not brought into direct contact, there is little change in the pressure of the steam, and there is no pressure fluctuation to the steam generation source. Further, although noise is generated when the steam directly hits water, the steam collecting apparatus 10 of the present invention can be an apparatus without such noise.

  Since steam always flows into the steam collecting device 10, there is no need for sterilization and cleaning, and the housing 12 can be a closed body.

  As described above, since the steam collecting device 10 can be configured in a small size, the steam collecting device 10 can be portable and portable. Therefore, when the location of the steam generation source changes with time due to work rotation, the steam collecting device 10 can be moved along with the change of the steam generation source. For example, when the steam generation source is a tank that performs sterilization using steam, the tanks that perform sterilization work are sequentially replaced. Therefore, the steam collecting device 10 is carried to the tank being steam sterilized, and the hook portion 46a is appropriately attached to the tank. It is possible to collect the steam by hooking it onto the tank or by standing by the legs 46b and connecting the steam outlet of the tank and the steam inlet 14 with a hose or the like. After completion of the work, the vapor collecting device 10 can be appropriately carried to another place and used or stored there.

  The vapor collecting apparatus 10 can achieve a great effect even though it is small. Examples thereof will be shown below.

  A plate-type heat exchanger 20 having a cooling capacity of about 60 kW was used, and a portable steam collector 10 having dimensions of a height of 320 mm, a width of 160 mm, and a depth of 160 mm was configured as the casing 12.

  The steam inlet 14 was connected to a steam outlet of a tank during steam sterilization, which is a steam generation source having a steam discharge amount of 40 kg / h. Moreover, the water inlet 16 was connected to the water supply source, and the amount of water from the water supply source was adjusted to 1484.52 L / h.

  Using this steam collecting device 10, the steam discharged from the tank was collected. However, in order to measure the effect of the steam collecting device 10, the flow rate of the hot water discharged from the first outlet 28 is measured in terms of mass without connecting the first outlet 28 and the second outlet 30. 0.05 kg / h. Since this hot water is condensate from the collected steam, a capacity of about 80.12% is obtained as a collection capacity. The temperature difference of water was 14.88 ° C., and the temperature difference of steam was 52.14 ° C.

  Changing the amount of water changes the water outlet temperature, but there is no significant change in the collection capacity and condensate temperature.

  Assuming that steam has been collected from 10 tanks by this steam collecting device 10, it becomes 32.05 × 10 = 320.5 kg / h, and when this is converted into the latent heat of steam, the heat of 241 kW is removed. become. In other words, changes in temperature and humidity corresponding to the amount of heat can be suppressed.

It is a perspective view of the steam collection apparatus by this invention. 1 is a perspective view of a steam collecting device according to the present invention. It is a perspective view of the heat exchanger of the steam collection apparatus by this invention. It is a disassembled perspective view of the heat exchanger of the steam collection apparatus by this invention.
