ることができる。As a result of the above operation, according to the characteristic configuration of the present invention, the paint mist is collected in a form in which the cleaning area is formed in the middle of the air passage (that is, the cleaning area, which is a droplet collecting area, has an air velocity. The paint mist is collected in the middle of the squeezing air passage to maintain high speed.
Is performed in two stages during the passage in the throttle air passage, it is possible to obtain a very high paint mist collecting efficiency as a whole.

上し得る。Moreover, while ensuring a high paint mist collecting efficiency as described above, it is possible to effectively prevent the noise generated by the second-stage paint mist collecting from leaking to the inlet side of the throttled air passage. As shown in Fig. 4, compared with the conventional type in which only a one-step cleaning area is provided below the inlet of the air passage, the efficiency of paint mist collection is improved by reducing the cross-sectional area of the air passage and increasing the amount of cleaning liquid. It is possible to reduce the noise leaking from the throttle passage to the coating room side, and improve the working environment in the coating room.

The cleaning liquid W that has passed through the upstream throttle air passage 12A at high speed is discharged to the upstream exhaust chamber 11A, and the cleaning liquid W discharged to the upstream exhaust chamber 11A is stored in the intermediate cleaning liquid tank 1
0A, and subsequently, the gas A in the upstream side exhaust chamber 11A, together with the overflow cleaning liquid W from the intermediate cleaning liquid tank 10A, flows at high speed in the downstream throttle air passage 12B, which also has the same one-stage trapping configuration as the conventional one. A form in which the paint is passed through and discharged to the downstream side exhaust chamber 11B (that is, a form in which the paint mist collection in the conventional form shown in FIG. 4 is simply performed in two stages) is also conceivable.

く。However, in this type, the trapped paint component in the cleaning liquid W discharged from the upstream throttle air passage 12A to the upstream exhaust chamber 11A is stored in the intermediate cleaning liquid tank 10A in the cleaning liquid storage process (that is, the first-stage paint mist). In the process from the collecting process to the second stage paint mist collecting process), the number of places requiring cleaning maintenance increases, and the exhaust chambers are divided into the upstream exhaust chamber 11A and the downstream exhaust chamber 11B. Each exhaust chamber 11A, 11
Since the maintenance work itself for B becomes difficult to perform, the maintainability is drastically reduced, and in order to prevent the paint accumulation in the intermediate cleaning liquid tank 10A, the cleaning liquid W discharged from the upstream throttle air passage 12A is discharged to the downstream side. Baffle 12B
If the form in which the fresh cleaning liquid is supplied to the downstream throttled air passage 12B is adopted instead of the form in which the cleaning liquid is reused, the amount of the necessary cleaning liquid as a whole is greatly increased, and the running cost is increased.

グコストの増大をも回避できる利点がある。In this respect, according to the characteristic configuration of the present invention (see FIG.
In the process from the first-stage paint mist collecting step to the second-stage paint mist collecting step, the cleaning liquid W1 flows down the upwardly inclined wall surface a at a high speed due to the high-speed gas flow in the restricted air passage 12, Although the cleaning liquid W used for collecting the paint mist by the eye is reused for collecting the paint mist by the second step, it extends from the paint mist collecting step of the first step to the paint mist collecting step of the second step. The coating material can be effectively prevented from being accumulated in the process, and the exhaust chamber 11 does not need to be divided into two parts. Therefore, it is possible to avoid the deterioration of the maintainability and avoid the increase of the required cleaning liquid amount to reduce the running cost. There is an advantage that an increase can be avoided.

せるようにしてある。On the other hand, with respect to the other side wall 19 of the throttle air passage 12, the upstream side portion 19A is a vertical wall, while the downstream side portion 19B is arranged in a front-down inclined posture substantially parallel to the downward wall surface c. In this way, the downstream side portion of the throttle air passage 12 is used as a downward inclined air passage, and the airflow A in the air passage is diverted to the side of the downward wall surface c at the wall surface diverting portion b.

集を絞り風路１２内で行うようにしてある。In other words, with the above-described air passage structure after the first cleaning area S1, the air flow path A in the air passage is turned toward the downward wall surface c at the wall turning portion b.
The washing water W1 flowing downward from the wall surface is separated and scattered from the wall surface turning portion b toward the predetermined second cleaning area S2 below the downward wall surface c in the restricting air passage in the state of being atomized in the air flow A in the air passage. As a result, the wall surface deflecting portion b is used as the second cleaning water spouting portion H2 for the second cleaning area S2, and the same water droplet collecting area as the upstream first cleaning area S1 is reformed in the second cleaning area S2. Therefore, by catching the residual paint mist in the passing gas A in the second cleaning zone S2 by water droplets, the second-stage paint mist collection subsequent to the upstream first-stage paint mist collection is squeezed. This is done in the air passage 12.

る。Further, in the above-described air passage structure, the throttle air passage portion on the downstream side of the wall surface deflecting portion b is provided with the upward inclined wall surface a and the downward wall surface c, so that the first cleaning area S1 and the squeeze air above the first cleaning area S1. When the blind spot is seen from the passage inlet 12a, moreover, a large number of water droplets in the first cleaning area S1 are absorbed by the high sound absorption characteristic of the water droplets in response to the noise generated in the throttle wind passage portion on the downstream side of the wall surface turning portion b. The noise reduction function of the noise reduces the noise (mainly water splattering noise) generated in the throttle wind passage downstream of the wall turning portion b in order to collect the paint mist in the second stage. While suppressing leakage to the inlet 12a side, and thereby ensuring high paint mist collecting efficiency as a whole by the paint mist collecting in two stages described above,
It is intended to effectively reduce the noise leaking from the squeeze air passage 12 to the side of the coating room 1 to improve the working environment in the coating room 1.

ら塗装室１側への漏出騒音の低減に寄与する。On the side of the other side wall 19 of the first cleaning area S1 in the restricted air passage 12, a cavity 20 is formed which is surrounded on three sides by the bottom of the wash water tank 10 and the other side wall 19 of the restricted air passage 12. However, the presence of the hollow portion 20 also contributes to the reduction of leakage noise from the throttle air passage 12 to the coating chamber 1 side.

るようにしてある。In the throttle air passage 12, the air passage cross-sectional area at the wall surface turning portion b as the second wash water outlet portion H2 is the air passage in the first wash water outlet portion H1 arranged at the throttle air passage inlet 12a. It is made smaller than the cross-sectional area, whereby the air flow velocity V2 in the second wash water spouting portion H2 is made larger than the air flow velocity V1 in the first wash water spouting portion H1, and the second wash water spouting portion is formed. The particle size of the water droplets formed by the atomization accompanying the scattering of the washing water from H2 is made smaller than the particle size of the water droplets formed by the atomization due to the scattering of the cleaning water from the first washing water spraying part H1. Therefore, in the first-stage paint mist collection in the first cleaning zone S1, a relatively large-diameter paint mist is collected by large-sized water droplets, and the second-stage paint mist in the second cleaning zone S2 is collected. Mist collection collects residual paint mist of relatively small diameter by water droplets of small diameter In the so that, it is to ensure that collected coating material mist passing gas A wide mist particle size range.

音の全体としての低減に有効となる。Further, at such an air flow velocity setting, the noise generated by the paint mist collection in the second stage is larger than the noise generated by the paint mist collection in the first stage. However, also from this, as described above, in order to collect the paint mist in the second stage, the noise generated in the throttle air passage portion on the downstream side of the wall turning portion b is directed to the throttle air passage inlet 12a side. It is effective to reduce the leakage noise to the coating chamber 1 side as a whole by suppressing the leakage of water by the barrier action of the upwardly inclined wall surface a and the downward wall surface c and the sound absorbing action of water droplets in the first cleaning area S1. ..
