Abstract

A spray application system includes an enclosed spraybooth area in which airborne particles are generated and a scrubber system is located below the enclosed spraybooth area. The scrubber system includes an inlet receiving water and air from the spraybooth area along with airborne particles. The scrubber system transfers the airborne particles to the water for cleaning the air. A generally downwardly opening noise reflector is located directly over the inlet of the scrubber system and is configured to reflect sound generated by the scrubber system back into the inlet of the scrubber system. The reflector is spaced from the inlet of the scrubber system a distance equal to approximately the width of the inlet.

Claims

1. A spray application system including an enclosed spraybooth area in which airborne particles are generated and a scrubber system located below said enclosed spraybooth area having an inlet receiving water and air from said spraybooth area including said airbourne particles and said scrubber system transferring said airboume particles to said water, cleaning said air, the improvement comprising:

a generally downwardly opening noise reflector located directly over said inlet of said scrubber system configured to reflect sound generated by said scrubber system back into said inlet of said scrubber system and being spaced from said inlet of said scrubber system a distance equal to approximately the width of said inlet.

2. The spray application system defined in claim 1, wherein said noise reflector is generally arcuate opening toward said inlet of said scrubber system.

3. The spray application system defined in claim 2, wherein said noise reflector is generally semicircular.

4. The spray application system defined in claim 3, wherein said generally semicircular noise reflector includes a diameter generally equal to twice said width of said inlet of said scrubber system.

5. The spray application system defined in claim 1, wherein said noise reflector includes a width generally equal to said width of said inlet of said scrubber system.

6. The spray application system defined in claim 1, wherein said spray application system includes a floor spaced above said inlet of said scrubber system and said noise reflector is suspended from said floor.

7. The spray application system as defined in claim 1, wherein said noise reflector is formed of at least one metal sheet and a polymeric sheet affixed to said at least one metal sheet further reducing the noise generated in said enclosed spraybooth area by absorbing noise generated by said scrubber system.

8. The spray application system defined in claim 7, wherein said noise reflector is formed of a laminate comprising outside metal sheets and a polymeric inner sheet sandwiched between said metal sheets.

9. The spray application system defined in claim 8, wherein said metal and polymeric sheets have approximately the same thickness.

10. The spray application system defined in claim 8, wherein said polymeric sheet comprises a polymer capable of absorbing vibrational energy derived from noise emanating from said scrubber system.

11. A paint application system including an enclosed paint spray area in which airbourne paint particles are generated and a scrubber system located below said enclosed paint spray area having an inlet receiving water and air from said enclosed paint spray area including said airbourne paint particles and said scrubber system transferring said paint particles to said water, cleaning said air, the improvement comprising:

a noise reflector located directly over said inlet of said scrubber system configured to reflect sound generated by said scrubber system back into said scrubber system inlet and being spaced from said inlet of said scrubber system a distance equal to approximately the width of said inlet of said scrubber system and said noise reflector having a width approximately equal to said width of said inlet of said scrubber system.

12. The paint spray application system defined in claim 11, wherein said noise reflector is generally arcuate opening towards said inlet of said scrubber system thereby reflecting sound generated by said scrubber system back into said inlet of said scrubber system.

13. The paint spray application system defined in claim 12, wherein said noise reflector is generally semicircular.

14. The paint spray application system defined in claim 13, wherein the diameter of said semicircular noise reflector is generally equal to twice said width of said scrubber system inlet.

15. The paint spray application system defined in claim 11, further including a floor spaced above said scrubber system inlet and said noise reflector is suspended from said floor.

16. The paint spray application system defined in claim 11, wherein said noise reflector is formed of a metallic sheet and a laminated polymeric sheet damping the noise generated by said scrubber system into said paint spray area through said scrubber system inlet.

17. The paint spray application system defined in claim 11, wherein said noise reflector is formed of a laminate including thin metallic sheets and a polymeric damping layer of viscoelastic material sandwiched between and laminated to said metallic sheets.

22. The paint spray application system defined in claim 11, wherein said sound damping reflector is formed of metal sheets having a damping layer sandwiched between and bonded to said metal sheets.

18. A paint spray application system including an enclosed paint spray area in which airboume paint particles are generated and a scrubber system located below said enclosed paint spray area having an inlet receiving water and air from said enclosed paint spray area including said airbourne paint particles, and said scrubber system transferring said paint particles to said water, cleaning said air, the improvement comprising:

a sound damping reflector located directly over said scrubber system inlet reflecting noise generated by said scrubber system through said inlet away from said paint spray area and being formed of a metallic sheet and a sound damping layer.

19. The paint spray application system defined in claim 18, wherein said sound damping reflector is generally arcuate opening downwardly towards said scrubber system inlet reflecting noise generated by said scrubber system towards said scrubber system inlet.
