Abstract
The utility model provides a diversion and depressurization silencer for boiler tail gas treatment. The diversion and depressurization silencer is composed of an outer brick-and-cement wall, a bevel diversion device, a tail gas outlet and a fan duct, wherein a sound-absorbing material is attached to the inner wall of the outer brick-and-cement wall. The diversion and depressurization silencer can greatly reduce the noises of tail gas. Besides, the diversion and depressurization silencer has the advantages that the silencer is simple in structure, economical and practical, is suitable to be popularized in small and medium-sized enterprises and the like.
Description
Technical field
The utility model relates to a kind of water conservancy diversion step-down silencing means that boiler exhaust gas is handled that is used for.
Background technology
Country has put into effect multinomial environmental protection policy, and the public's environmental consciousness is also constantly improving, and boiler is a necessary tool in industry and the life, and this just need handle the tail gas of boiler effectively, thereby reaches the effect of dedusting, noise reduction.
At present, domestic most of boiler exhaust gas is handled main dedusting, the noise reduction one treatment technology of adopting; The patent No. like Wang Baijun is the deduster that is adopted in CN1303725 " boiler noise-suppressing smoke-eliminalting desulfurization bionic nasal cavity type dust-removing equipment design method ", and this equipment designs according to the bionic nasal cavity structural principle, in deduster, is provided with web plate, absorption heap, water conservancy diversion blower fan, circulation flushing pipeline and access cover etc.; Make deduster realize the dedusting method that twice absorption is once filtered and washed; Can improve efficiency of dust collection, can realize the function of desulfurization, noise reduction during dedusting, but input cost be high; Structure is more complicated also, also is unfavorable for maintenance.
Summary of the invention
The utility model is in order to overcome the weak point in the above-mentioned technology, and a kind of water conservancy diversion step-down silencing means that boiler exhaust gas is handled that is used for is provided.
The water conservancy diversion step-down silencing means that the utility model is mentioned is realized through following mode: water conservancy diversion step-down silencing means mixes exterior wall, knuckle guiding device, tail gas outlet and blower fan airduct by brick and constitutes; Said brick mixes has sound-absorbing material on the outer inner wall, said blower fan airduct is the inlet of boiler exhaust gas.
The angular extensions alpha of the knuckle guiding device of the utility model is 60 °～150 °, and preferable range is 80 °～100 °.
The sound-absorbing material of the utility model can be polyester sound absorption cotton, foamed plastics, mineral wool, mineral wool etc.
The beneficial effect of the utility model is, greatly reduce the noise that boiler exhaust gas is handled, and common brick mix structure is simple, and is economical and practical, is applicable in the medium-sized and small enterprises and promotes.
Description of drawings
Fig. 1 is a water conservancy diversion step-down silencing means sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Like Fig. 1; Water conservancy diversion step-down silencing means comprises that brick mixes exterior wall 11, knuckle guiding device 12, tail gas outlet 13 and blower fan airduct 14, and said brick mixes on the exterior wall with sound-absorbing material 15; The knuckle angle [alpha] scope of knuckle guiding device 12 is 60 °～150 °, and preferable range is 80 °～100 °.
As shown in Figure 1, sound-absorbing material 15 can be polyester sound absorption cotton, foamed plastics, mineral wool, mineral wool etc.
The utility model workflow: boiler exhaust gas gets into water conservancy diversion step-down silencing means from the blower fan airduct; Through the knuckle guiding device, because the energy dissipating effect of knuckle guiding device reduces air velocity; And air-flow is when getting into silencing means; The space increases reduces stream pressure, and the roughness and the sound-absorbing material all around of the mixed exterior wall of brick have also played certain sound-absorbing effect simultaneously, and last tail gas is discharged through the tail gas outlet.
The present boiler exhaust gas noise problem in handling that the utility model has adopted simple device solves makes from about the original 100dB, is reduced to be lower than 10dB, and also economical and practical, be applicable in the medium-sized and small enterprises and promote.
Claims (7)
