Description
Technical field
The present invention relates to a kind of sound arrester, particularly relate to a kind of cylinder silencer that is used for prebaked cell for aluminum-reduction.
Background technology
Existing cylinder silencer is all the monomer sound damper, directly is installed on single cylinder exhaust port place with thread connecting mode or alternate manner, as copper sintered type sound damper, screen mesh type sound damper, micropole diffusor etc.; The weak point of these sound dampers is that erasure effect, resistance of exhaust, work-ing life etc., comprehensively use properties was bad.Wherein copper sintered type sound damper on prebaked cell for aluminum-reduction blanking cylinder work-ing life less than 1 month; And the resistance of exhaust of copper sintered type sound damper is big, causes hitting electrolyte shell surface strength when using and reduce on crust breaking cylinder, and the tup recovery time is long, thereby has reduced the work-ing life of tup.Screen mesh type sound damper, micropole diffusor and micropole diffusor erasure effect are poor, are difficult to satisfy on-the-spot requirement to the noise pollution standard.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, a kind of good muffling effect, long service life is provided, does not influence that tup uses and noise is shifted out the cylinder silencer of prebaked cell for aluminum reduction of on-the-spot noise reduction.
Cylinder silencer of prebaked cell for aluminum reduction of the present invention, be achieved by following technical proposals, the present invention is spread main line by one-level air pressure diffusion bye-pass, secondary air pressure and is shifted out on-the-spot exhaust line and form, and described one-level air pressure diffusion bye-pass is made of cylinder exhaust port joint, sebific duct, pipe collar, elbow, double end screwed pipe and the screw thread threeway between crust breaking cylinder, blanking cylinder and secondary air pressure diffusion main line; Described secondary air pressure diffusion main line is made of joint and horizontal main line steel pipe on the upper part of the electrolytic cell surface; Describedly shift out on-the-spot venting port pipeline and constitute by steel square elbow and exhaust steel pipe.
Cylinder silencer of prebaked cell for aluminum reduction of the present invention compared with prior art has following beneficial effect: owing to adopted the air-flow guidance mode of I and II air pressure diffusion, so exhaust is unobstructed, the tail windresistance is little, and because air pressure is that leading Party group spreads step by step in sound damper of the present invention, air-flow velocity also is that leading Party group reduces step by step, so the noise that flow perturbation produces is little; Shifting out on-the-spot exhaust ports is the air-flow of relatively low pressure, low speed, and the noise that produces in the exit reduces; And, the noise effect of operation field is further reduced, so sound damper good muffling effect of the present invention because this venting port shifts out operation field.Through actual measurement, sound damper of the present invention reduces the 16-20 decibel than the electrolyzer noise of steel sintered type sound damper.Because sound damper of the present invention mainly adopts metal steel pipe and elastomeric material to make, and is firm in structure durable, long service life.
