TL;DR: In this article, an apparatus and process for reclaiming paint overspray from a paint-laden air stream exiting a spray booth is described, which utilizes a packed spray tower with captured paint over spray as its scrubbing liquor.
Abstract: An apparatus and process for reclaiming paint overspray from a paint-laden air stream exiting a paint spray booth. A preferred embodiment of the apparatus utilizes a packed spray tower with captured paint overspray as its scrubbing liquor. The scrubbing liquor is recirculated through the tower until it reaches a sufficient concentration of paint for reuse in the paint operation.

TL;DR: In this paper, a bent duct downstream of an oxidizing vessel and spraying alkaline aqueous solution at a point upstream of at least one bent portion of the duct is provided.
Abstract: PURPOSE: To accomplish the high denitration efficiency using small installation area at reduced installation and the operation cost by providing a bent duct downstream of an oxidizing vessel and spraying alkaline aqueous solution at a point upstream of at least one bent portion of the duct. CONSTITUTION: Tunnel ventilation air containing nitrogen monoxide of 3ppm is lead to an electron beam irradiation reactor 1 to apply electron beam of 0.3kGy to the air by means of an electron beam irradiation device 2. Next, an aqueous solution of potassium carbonate of pH10 is sprayed from a spray nozzle 4 provided at the inlet of bent duct 7 having a sectional area of 1m and total length of 15m which is bent at four points in such a manner that liquid amount-to-gas amount ratio is 0.1kg/m and average particle diameter of liquid droplet is 2mm. If the gas is lead to an outlet 6 through an electrostatic precipitator 5, denitrifying efficiency for the same residence time is higher than in the case of a spray tower, and concentration of liquid droplets in the gas remains unchanged even with higher gas flow velocity than in the spray tower.
