In the figure, 6 is a bag tube, 7 is a housing, 7A is a passage, 8 is an apron, and 10 is a small hole. A large number of small holes 10 are formed on the top surface of the long bag tube 6 in the longitudinal direction at predetermined intervals. The housing 7 is fixed to the bag tube 6, and a space is formed in the upper part. As shown in FIG. 13, both sides of the housing 7 are cut off at regular intervals to form a passage 7A for a liquid to be sprayed. On the other hand, a roof-shaped apron 8 is attached to the lower surface of the bag tube 6. The liquid that has flowed into the bag tube 6 is jetted out of the small hole 10 into the space formed by the housing 7, travels along the surface of the bag tube 6 through the notched passage 7 </ b> A, flows down the surface of the apron 8, and flows through the heat transfer tube. 5 is evenly sprayed.

は構造的に複雑で組立てが難しく、コストがかかる欠点
がある。In the spraying device disclosed in the above-mentioned Japanese Utility Model Publication No. 53-52682, a large number of passages 7A must be attached to the gutter 1, and a lot of man hours are required for the assembling work. In addition, when the siphon plate 2 is attached to the gutter 1, the dispersion of the liquid becomes uneven unless the gap between the siphon plate 2 and the side wall of the gutter 1 is made uniform. However, it is extremely difficult to assemble the gap uniformly. Furthermore, even if the siphon plate 2 is completely assembled on the side wall of the gutter 1, if the spraying device itself is inclined, the spraying becomes uneven. Further, the spraying device disclosed in Japanese Patent Application Laid-Open No. 51-51039 has a drawback that it is structurally complicated, difficult to assemble, and costly.
本発明の目的は、構造が単純で組立て易く、多少、液
の散布状態が常に均一でねらったところに正確に液を滴
下することができ、また、散布装置内に異物が入っても
目づまりなどを起こして散布状態が不均一にならないよ
うに液体の散布装置を提供することにある。An object of the present invention is that the structure is simple and easy to assemble, and that the liquid can be accurately dropped at a target where the spraying state of the liquid is always uniform. It is an object of the present invention to provide a liquid spraying device so that the spraying state does not become non-uniform due to the above.

よって達成される。The above object is to form a gap on the outer periphery of the bag tube with the outer peripheral surface of the bag tube, attach a baffle plate, squirt liquid from a small hole provided in the bag tube, apply the liquid to the baffle plate, and drop a droplet. In the spraying apparatus, both side surfaces of the bag tube are formed in parallel planes, and a plurality of small holes are provided in the longitudinal direction of the bag tube. This is achieved by mounting an open baffle on the perforated side of the bag tube.

る。さらに、小孔から出た散布液はガイドスペーサのと
ころで急に、流路が拡大されて流速が落ちるので、最終
的に、散布装置からはゆっくりと液が散布される。Because the level of the stoma is higher than the bottom of the bag tube, even if foreign matter enters, it accumulates at the bottom of the bag tube and does not come up to the stoma, so the stoma does not clog, always,
A required amount of liquid to be sprayed can be spouted. Even if the assembling accuracy of the spraying device is somewhat poor, or the spraying device is slightly inclined, the liquid can be uniformly discharged from any of the small holes. Further, the spray liquid that has come out of the small holes is suddenly enlarged at the guide spacers and the flow velocity is reduced, so that the spray liquid is finally slowly sprayed from the spray device.

ことがない。In the figure, 6A is a bag tube, 9A is a baffle plate, 10A is a small hole, 1
1A is a flow path, 12A is a guide spacer, 13A is a space, 14A is an opening, 15 is a liquid flow, and 16A is a bottom. The horizontally arranged bag tube 6A is formed of a long rectangular pipe having an opening 14 into which a liquid flows, and a large number of small holes 10A are provided at predetermined intervals at a high level on a side wall in the longitudinal direction. The diameter of the small holes 10A is made slightly smaller so that the liquid can be uniformly sprayed from any of the small holes even if the spraying device is inclined during the spraying operation. In other words, the diameter of the small hole 10A is determined so that the pressure loss when the liquid flows out of the small hole 10A is larger than the pressure loss of the flow path 11A through which the liquid in the bag tube 6A flows. Sprayed on. The guide spacer 12A is provided with a space 13A by hollowing out the periphery of the guide hole 12A in accordance with the position of the small hole 10A, and an opening 14A is provided in the direction of spraying. Further, a baffle plate 9A is provided beside the guide spacer 12A so that the guide spacer 12A
Is fixed so as to be sandwiched between the bag tube 6A and the baffle plate 9A.
By doing so, the liquid flowing into the bag tube 6A squirts from the small hole 10A into the space 13A surrounded by the guide spacer 12A, the baffle plate 9A, and the bag tube 6A. The ejected liquid first spreads in the direction of the arrow in the space 13A, causing the flow velocity to drop.
The liquid slowly flows down from the opening 14A of the 12A and operates so as to drop the liquid to a predetermined position such as the heat transfer tube 5. As a result, the liquid jumps out of the spraying device and heat transfer tubes 5
In such cases, the liquid does not scatter. In addition, small holes 10
Since A is opened at the high position of the bag tube 6A, even if foreign matter enters, it accumulates on the bottom 16A of the bag tube 6A and does not reach the small hole 10A. There is no unevenness.

FIG. 6 is a sectional view taken along the line VI-VI of FIG. 5, to which the present invention is applied as an apparatus for spraying a lithium bromide solution in an absorber of an absorption refrigerator. In this embodiment, the space 13C has a circular shape centered on the small hole 10A, and the right blind tube 6A in FIG. 8 uses the side wall of the left blind tube 6A in place of the baffle plate 9A. . The basic configuration and operation of the spraying device are the same as those in FIGS. The sprayed liquid stream 15 once enters the tray 17 of the heat exchanger, and then enters each heat transfer tube 5 to absorb refrigerant vapor and exchange heat.

FIG. 8 is a cross-sectional view taken along the line VIII-VIII of FIG. 7, and is a simplified version of the baffle plate 9E corresponding to the baffle plate 9C of FIGS. The space 13D from which the liquid is ejected from the small holes 10A is all integrated to form a single opening 14D. In this way, the droplets to be dropped become finer, and the distribution of the liquid to the heat transfer tubes 5 is further uniformed in the longitudinal direction. According to the present embodiment, it is possible to realize a spraying device that accurately sprays a predetermined amount of liquid to many heat transfer tubes 5.
