Description of the invention (0 (Please read the precautions on the back before filling out this page) The present invention is about spraying the paint sprayed in the paint, which attracts the paint mist that is not spread on the paint. The coating room that captures and recycles; in particular, the use of an exhaust fan to attract paint mist with the airflow, and after the paint mist is captured and treated in the painting room, it becomes a painting room where clean air is discharged to the outside air. The invention is particularly effective for a water-washing painting room in which a water-washing spray nozzle is installed in the painting room, and the density of the sprayed mist is used to capture paint particles. [Advanced Technology] A general water-washing painting room, such as the third As shown in the figure, a water tank 45 is arranged in the lower part, and the exhaust fan 41 is used to suck the mist in the front of the painting room containing airflow. When passing through the mist processing chamber 4 3, the mist is sprayed from the washing shower head of the nozzle 4 4 to spray the mist with Water is dropped into the lower water tank to be captured together, and the water sucked up by the pump is supplied from the aforementioned nozzle 44, and is also supplied to the water conveyance tank 46 which overflows to the water flow plate 42 provided in front of the painting room. Assume The coating material captured in the mist processing chamber 4 3 in the rear of the water flow plate and the water flow plate is dropped into the water tank as a sediment to be separated and recovered. This coating room is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs because it is The contact with water is used to capture the mist of the diffused paint, so that it increases the chance of contact and improves the capture efficiency, which can improve the purification of the exhausted air and prevent air pollution and environmental pollution. An effective method is to often spray The method of catching the sprayed water formed by the shower is usually formed by setting a water flow plate in front of the painting room to circulate the water. The water flow is used for one capture, and the aforementioned shower is arranged inside the rear of the water flow plate. Processing room for mist. This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 552160 A7 B7 V. Description of the invention (2) The problems of this type of water-washing coating, including the shower, are listed in the shower. There are two kinds of sounds: the sound of water spray and the sound of the fan. That is, the water washing spray is arranged by the rear side of the water flow plate. The spray nozzle sprays the mist-like 7jC into the airflow through the duct. The spray sound is high and is transmitted to the painting room from the opening that is also the suction port. In addition, the spray spray is directly sprayed onto the back of the water flow plate, which becomes a conflict. The sound is transmitted to the painting room side. These noises are transmitted to the operator of the painting room through compounding, which becomes noise and hinders the efficiency of the work. (Problems to be solved by the invention) It is also a basic function of the painting room to maintain it to the maximum. Under the effect of mist collection, the generation of sound transmitted to the painting room side is reduced, and a painting room that achieves a quieter and good working environment is the subject of the present invention. Especially when the mist treatment device is sprayed with water in the treatment room When the water is sprayed, the mist-like water captures the mist in the passing air flow, and when the radon purification of the exhaust air is achieved, it is the first purpose to effectively reduce the ejection sound generated inside and the sound hitting the wall surface. (Means for solving the problems) In order to solve these problems, the present invention is characterized in that the flow path of a wind tunnel provided with a spray nozzle for water washing shower, which is a source of noise, is inclined to an opening portion provided on a lower front surface so that The airflow path up to the opening is curved to form a black hole communicating with the front opening. '' Through these structures, the spray sound does not directly face the opening, so the generated sound conflicts with the wall surface forming the black hole, and after attenuation, it is communicated that this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) • Li! (Please read the notes on the back before filling out this page}-Ordered by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -5- 552160 A7 B7 V. Description of the invention (3) Go to the painting room. Noise source The place to be placed is an inclined surface, and the noise is sent directly to the outside. (Please read the precautions on the back before filling this page.) Furthermore, the spray direction of the spray water is a wide-angle spray in the direction of the central airflow, and conflicts with the oblique front direction. The wall surface and the inclined wall surface are formed separately from the wall surface (water flow plate) facing the painting room, and the sound of the shower water collision is not the same as that described above, and does not reach the opening directly. The black hole from the inclined air flow path to the opening makes it The effect of bending is even greater. In addition, the noise of the exhaust air that is absorbed with the sound of the shower is also before the suction port. There is a detour in the surrounding area, and a shield plate is provided so that the sound of the exhaust fan is not directly transmitted to the opening of the painting room. The noise passing through the shield plate is gradually reduced according to the curved path described above, and the noise from the opening can be large. [Embodiment] [Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the first picture is a cross-sectional view viewed directly from the side of the painting room. The lower water tank 1 is divided into a front water tank 1 A and a rear water tank 1 B. A mist processing chamber 3 is provided at the center, and an exhaust fan 4 is installed at the upper part. A water supply tank 5 is provided at the upper part of the front of the processing chamber. 5 The water flow plate 6 is lowered downward. The water flow plate 6 is composed of an upper water flow plate 6 A and a lower water flow plate 6 B in consideration of ease of manufacturing and maintenance. The lower end of the lower water flow plate 6 B is opened through the suction inlet. 7 And the suction air flow of the exhaust fan 4 is attracted at a moderate flow rate. The mist processing chamber 3 is the path of the suction air flow of the exhaust fan 4, and the Chinese paper standard applies Chinese national standards. (CNS) A4 specification (210X297 mm) -6-552160 A7 B7 V. Description of the invention (4) The spray nozzle 8 with water washing and showering is installed in the part, and it is sprayed through the airflow. (Please read the precautions on the back before filling in this Page j Spray nozzles 8. A plurality of nozzles are lined up from the front of the painting room to the left and right, and the spray water sprays the entire area of the air flow path in the processing chamber. The spray formed by the shower uses a wide-angle nozzle to conflict with the oblique front wall surface. Therefore, the jetting sound of the shower and the conflicting sound of the surrounding wall surface occur. In addition, a guide plate 9 is formed between the upper exhaust fan and the lower suction port, and the airflow is formed to flow into a wind tunnel that partially bends it. Jetting The nozzle 8 is disposed in the wind tunnel inclined to the opened suction opening in the curved wind tunnel, and sprays it backwards with respect to the airflow passing therethrough, so that the center of the spray direction is positioned parallel to the guide plate 9. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Furthermore, the guide plate 9 is installed on the wall of the wind tunnel where the wide-angle jetting water is in conflict, so that it does not become a shield plate or a water flow plate facing the painting room. Fig. 2 is a diagram illustrating the formation of a wind tunnel, a is a past wind tunnel, and b and c are examples of the present invention. In the past, the sprayed water was directly sprayed onto the water flow plate, and the spray direction was directed toward the opening portion. However, the examples of b and c are structures in which the sprayed water collides with the guide plate 9 A which is separated from the water flow plate. In a curved wind tunnel where the nozzle that is also the source of sound does not directly face the opening, the generated sound is reflected to the opening and transmitted to the painting room through attenuation. Fig. 20 is a separator, which is provided together with the air flow to remove fine water droplets sucked into the exhaust fan 4. Figure No. 2 1 is a shielding plate installed directly in front of the exhaust fan to allow air to flow around it, preventing noise generated by the exhaust fan from directly propagating toward the lower opening, and preventing the lateral width from being relatively large. The airflow in the long wind tunnel is concentrated on the exhaust fan. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm)-7- 552160 A7 B7 V. Description of the invention (5) (Please read the precautions on the back before filling This page) causes uneven airflow. To maintain a uniform airflow in the wind tunnel, when the middle opening of the painting room is wide and the lateral width in the wind tunnel is wide, multiple exhaust fans are used. [Effects of the Invention] According to the present invention, the spray sound of water washing and showering propagates into the wind tunnel along the inclined plate that holds an angle to the opening of the coating room, and at least once reflects to the opening and transmits to the coating Installed in the room, so the attenuation is greatly reduced to achieve low noise reduction. In addition, the sound generated when the collision hits the wall surface is similarly attenuated, and the sound is not transmitted directly to the painting side, thereby reducing noise in the painting room. Furthermore, according to the present invention, a shielding plate is provided directly below the exhaust fan to prevent the operating sound of the exhaust fan from being transmitted to the opening on the coating room side through the mist processing chamber, thereby achieving noise attenuation. In addition, since the wall surface of the black hole portion does not directly face the painting room side, the passing sound of airflow is not transmitted. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed a device with an actual middle entrance of 1 m. Compared with the previous models, the noise level on the front 1.5 m was reduced from 7 7 d B (A) to 7 2 d. B (A). The larger the middle mouth, the larger the opening, and therefore the noise 上升 also increases. However, it has been confirmed that the reduction tendency is the same. In this way, according to the present invention, the noise is not directly transmitted from the source to the painting room. Compared with the past, the noise is greatly reduced, the operator's working environment is improved, and as a result, the operating efficiency is improved.
