Abstract
The invention discloses a water curtain deduster applied to thermal spraying, and relates to a ventilation, dedusting and smoke evacuation technology. The water curtain deduster applied to thermal spraying solves the problem that the existing thermal spraying technology utilizes an induced draught fan to carry out smoke evacuation treatment so that large-particle size dust cannot be removed effectively. The water curtain deduster applied to thermal spraying is characterized in that an inner cavity of a water tank is divided into a water storage tank and a drainage tank by a water-stop sheet; a stainless steel inclined plane plate is aslant arranged in an upper tank; a spray pipe is arranged at an upper part an upturned inclined plane of the stainless steel inclined plane plate; at least row of spray orifices are even arranged on the wall of the spray pipe in a spray pipe length direction; the spray orifices face to the stainless steel inclined plane plate; a center line of each one of the spray orifices forms an included angle of 45 degrees with a horizontal center line of the spray pipe; a flue gas guide plate is aslant arranged outside the upper tank; one end of a water spray connecting pipe is connected to the spray pipe and the other end is connected to a water pump; the water pump is connected to one end of a bend pipe; the other end of the bend pipe is communicated with the water storage tank; and a gas collecting hood is arranged at the center of the top of the upper tank. The water curtain deduster applied to thermal spraying is utilized for smoke dust removal in thermal spraying construction.
