Description
Technical field
The utility model relates to exhaust noise silencing apparatus field, particularly relates to a kind of multistage combined exhaust box.
Background technology
Steam boiler and the noise that sends about the discharge of steam of heat power equipment can up to 130 decibels, the numerical value that " industrial enterprise's noise hygienic standard " of promulgating considerably beyond China specifies.(such as: gauge pressure is the superheated vapor of 1kg/cm2, time from hole discharged to air, its speed just can reach 570-600 meter per second, and for saturated vapour, its speed also can reach 470-480 meter per second, like this steam of high speed, when discharged to air, owing to having exceeded the velocity of sound 340 meter per second, so the noise caused is very high).At present for suppressing high pressure draught displacement noise, had the sound suppressor of multiple pattern in the world, its principle adopts multi-level throttle step-down mostly, although noise power greatly weakens, but often because of many reasons such as steam discharge off-design values, make noise still higher than standard value.
Utility model content
The technical problems to be solved in the utility model is: in order to solve Problems existing in above-mentioned background technology, provides that a kind of sound deadening capacity is large, volume is little, high temperature resistant, uncorruptible multistage combined exhaust box.
The utility model solves the technical scheme that its technical matters adopts: a kind of multistage combined exhaust box, include one-level eliminate the noise acoustic tube in adapter, secondary muffler body, three grades of muffler bodies, level Four muffler body, hanging support, inside support ring, waterproof glass cloth, Pyatyi, six grades of muffler bodies, seven grades hinder acoustic shell, eight grades of muffler bodies.In described level Four muffler body, concentric is set with three grades of muffler bodies, secondary muffler body, one-level noise elimination adapter successively, is fixed by inside support ring; Described eight grades of muffler bodies are made up of orifice plate of eliminating the noise, waterproof glass cloth, six grades of muffler bodies, are fixed by upper and lower inside support ring.Eight grades of described muffler bodies are fixed on the shaft core position of exhaust box.Described hanging support has two, is positioned at the symmetria bilateralis position of exhaust box, fixing for installing.
Further, one-level noise elimination adapter, secondary muffler body, three grades of muffler bodies, level Four muffler bodies all adopt 304 stainless steels, corrosion-and high-temp-resistant.
Further, what six grades of muffler bodies adopted is alumina silicate sound absorber, and acoustically effective is good, high temperature resistant.
The beneficial effect that the utility model produces is: high pressure steam in exhaust box after one-level eliminates the noise adapter, secondary muffler body, three grades of muffler bodies, level Four muffler body flow control noise power greatly weaken, in Pyatyi, acoustic tube, six grades of muffler bodies, seven grades of resistance acoustic shells, eight grades of muffler bodies absorb residual noise effectively again, and total sound deadening capacity can reach 36 ~ 42 decibels.Senior middle school's low frequency noise can be effectively reduced compared with conventional muffler, high temperature resistant, corrosion-resistant, stabilized structure is not yielding.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A district of the present utility model enlarged drawing;
Fig. 3 is B district of the present utility model enlarged drawing;
In figure: 1. one-level is eliminated the noise and taken over, 2. secondary muffler body, 3. three grades of muffler bodies, 4. level Four muffler body, 5. hanging support, 6. eight grades of muffler bodies, 7. inside support rings, 8. waterproof glass cloth, 9. acoustic tube in Pyatyi, 10. six grades of muffler bodies, 11. 7 grades of resistance acoustic shells, 12. noise elimination orifice plates.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The multistage combined exhaust box of one as shown in Figure 1, 2, 3, includes acoustic tube 9, six grades of muffler bodies 10, seven grades resistance acoustic shell 11, eight grades of muffler bodies 6 in one-level noise elimination adapter 1, secondary muffler body 2, three grades of muffler bodies 3, level Four muffler body 4, hanging support 5, inside support ring 7, waterproof glass cloth 8, Pyatyi.In described level Four muffler body 4, concentric is set with three grades of muffler bodies 3, secondary muffler body 2, one-level noise elimination adapter 1 successively, is fixed by inside support ring 7; Described eight grades of muffler bodies 6 are made up of noise elimination orifice plate 12, waterproof glass cloth 8, six grades of muffler bodies 10, are fixed by upper and lower inside support ring 7; Eight grades of described muffler bodies 6 are fixed on the shaft core position of exhaust box.One-level noise elimination adapter 1, secondary muffler body 2, three grades of muffler bodies 3, level Four muffler bodies 4 all adopt 304 stainless steels, corrosion-and high-temp-resistant.Six grades of muffler bodies 10 adopt alumina silicate sound absorber, and acoustically effective is good, high temperature resistant.After high pressure steam accesses exhaust box by one-level noise elimination adapter 1, by noise power greatly being weakened after secondary muffler body 2, three grades of muffler bodies 3, level Four muffler body 4 flow control, in Pyatyi, acoustic tube 9, six grades of muffler bodies 10, seven grades resistance acoustic shell 11, eight grades of muffler bodies 6 absorb residual noise effectively again, and total sound deadening capacity can reach 36 ~ 42 decibels.Senior middle school's low frequency noise can be effectively reduced compared with conventional muffler, high temperature resistant, corrosion-resistant, stabilized structure is not yielding.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
