The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: circulating slurry sprinkling device for desulfurization of flue gas, it is characterized in that: comprise shower, connect box, connect cover plate, elbow, nozzle and flange, described connection box is pre-buried to be packed on the desulfurization Tata wall, the connection box is connected by securing member and is positioned at the connection cover plate in its outside, the bottom installs by flange and is fixed with shower in connecting box, shower one end is connected with elbow, the other end is connected with desulfurizing tower outer loop slurries pipeline by flange, is connected with nozzle on elbow.
The utility model can also adopt following technical scheme:
Described shower is the stainless steel structure.
Described elbow is that stainless steel is made, and its bending angle is 90 °.
Described nozzle is that stainless steel is made major path screw type nozzle arrangements.
Described connection box is the rectangular box that stainless steel is made, and before and after the box body and up and down the four sides is a Welding Structure, and the left side is an open ports, the right side by flange with to connect cover plate fixedly connected.
Described connection cover plate is the stainless steel structure.
A nozzle is housed on the described shower elbow.
Described securing member is stainless steel bolt and supporting stainless steel nut.
Advantage and the good effect that the utlity model has are: this circulating slurry sprinkling device for desulfurization of flue gas adopts major path screw type nozzle, by increasing the distance between the conveyor screw, make design allow the solid particle diameter that passes through identical with injection diameter, maximum can reach 38mm, has prevented the generation of spray nozzle clogging problem effectively.Shower by welding connection cover plate at one end be fixed on desulfurization Tata wall on connect box connection, connect box and be embedded in desulfurizing tower tower wall in advance, materials such as application clay connect sealing with the granite tower body, shower connects with the association box flange, has solved the drawback that traditional shower and desulfurizing tower interface wearing and tearing take place and reveal.Desulfurizing tower is in service can directly be extracted shower out and overhaul and do not need to shut down from the tower wall, easy to maintenance.In addition, all right batch production of circulating slurry sprinkling device for desulfurization of flue gas, mass manufacturing, production and transport are very convenient.
