摘要： PURPOSE:To prevent the generation of trouble due to dust accumulation on the wall part of a hopper by providing a dust collecting electrode for collecting dust with a skirt part extending in parallel to the wall of the hopper for receiving dust below. CONSTITUTION:At the lower end of a dust collecting electrode 1 placed near the wall of a hopper 3, a skirt part 5 extending in parallel to the wall of the hopper 3 is provided. The collected dust is shaken down by striking the dust collecting electrode 1 with a hammer 6. The dust collected near the wall of the hopper 3 does not fall in the wall part but falls onto the skirt part 5. The dust accumulated on the skirt part 5 is shaken down toward the center of the hopper 3 successively by striking it with the hammer 6. Therefore, the dust is prevented from being piled up on the wall part.

摘要： PURPOSE:To obtain a durable and inexpensive spraying device for cooling a high-temp. corrosive waste gas by enclosing a water feed pipe with the tip bent in the shape of an L in the gas flow direction and a spray nozzle at the tip of the feed pipe with a cylindrical L-shaped protective tube and vertically inserting the feed pipe and the nozzle into the passage of the high-temp. corrosive waste gas. CONSTITUTION:A lining 2 resistant to heat and acid is applied on the inner wall of a mild-steel shell 1 forming a gas passage, and the insertion port 3 of a spraying device is formed on the barrel part of the shell. As for the spraying device set in the insertion port 3, a spray nozzle 5 is connected to the tip of a water feed pipe 4 bent in the shape of an L in the gas flow downstream direction (shown by the void arrow), and a cylindrical L-shaped protective tube 6 is fixed to a lid 7 for fixing the entire spraying device to the insertion port 3 so that the water feed pipe 4 and nozzle 5 are enclosed. Consequently, the service life of the device is increased by >=25 times as compared with the conventional one, the material cost is reduced, and the labor cost for the exchange is remarkably saved.
