Abstract
The invention discloses a silencer for a safety valve for a chemical plant. The silencer comprises a silencer barrel, a partition plate, through holes, an upper end socket, a lifting lug, a support, a base, a lower end socket and an air inlet. The two ends of the silencer barrel are provided with the upper end socket and the lower end socket. The lifting lug is arranged on the upper end socket. The through holes are evenly formed in the outer wall of the silencer barrel. The support is arranged at the portion, close to the lower end, of the outer side of the silencer barrel. The air inlet is arranged in the lower end of the lower end socket. The silencer for the safety valve for the chemical plant has the beneficial effects that the structure is simple, compact and reasonable, assembling is convenient and rapid, and connection is reliable; the purpose of silencing is achieved by disturbing airflow and sound waves of the silencer, and noise is lowered; internal intake and exhaust are smooth, power losses are small, and the silencing effect is good; the working reliability of the silencer is greatly improved, and use and application are easy; an exhaust pipe will not bear large external force due to the fact that the silencer is placed, disassembling and overhauling are convenient, and displacement, taking-off and returning of the safety valve are not affected.
Description
Technical field
The present invention relates to the one of noise elimination clothing arts, be specifically related to a kind of chemical plant safety valve silencing apparatus.
Background technique
Chemical plant safety valve silencing apparatus is a kind of silencing apparatus, be mainly used in electric power, chemical industry, safety valve in the industries such as metallurgy, effective noise elimination of the high temperature and high pressure steam discharge of Pcv valve and exhaust steam valve, for boiler safety door and exhaust steam valve, it can look at is a constituent element of pipeline, after Acoustic treatment is made in inside, generation and the propagation of noise can be weakened, outlet silencing noise amount is made to reach 20 ∽ 30 decibels (A sound level), correspondingly loudness reduces by more than 50%, subjective sensation has positive effect, silencing apparatus is the device of abatement pneumatic noise, installed in the duct or enter, on relief opening, while air-flow passes through, to noise, there is certain consumption.Existing silencing apparatus is because complex structure, weight are large, high temperature oxidation sound absorption filler, high velocity air impacts sound absorption filler, the reasons such as aqueous vapor infiltration sound absorption filler, silencing apparatus is easy to occur that maintenance is frequent, soundproof effect is poor, the situations such as life cycle is short, soundproof effect is poor, and intake and exhaust resistance is larger, air flow property is poor, greatly reduces the reliability of silencing apparatus work.
Summary of the invention
Object of the present invention is just to provide a kind of chemical plant safety valve silencing apparatus to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of chemical plant safety valve silencing apparatus, comprise silencer cylinder, dividing plate, through hole, upper cover, hanger, bearing, base, lower seal head and suction port, described silencer cylinder two ends are provided with upper cover and lower seal head, described upper cover is provided with hanger, described silencer cylinder outer wall is evenly provided with through hole, outside silencer cylinder on lower side, described lower seal head lower end is provided with suction port to described bearing settlement.
Further, described silencer cylinder inside is provided with multiple dividing plate, and the opening of dividing plate is not on the same line and vary in size.
Further, described diaphragm internal is filled with sound absorption cotton.
Further, described arrays of openings triangularity or rectangular.
Further, described silencer cylinder bottom is provided with base.
Beneficial effect of the present invention is: this chemical plant safety valve acoustic wave filter structure is simple, compact and reasonable, fast easy to assembly, connect reliable, by upsetting the air-flow of silencing apparatus and sound wave thus reaching the object of noise elimination, reduce noise, inner intake and exhaust are smooth and easy, power loss is little, soundproof effect is good, substantially increasing the reliability of silencing apparatus work, be easy to use and promote, making outlet pipe can not bear larger external force because settling baffler, Disintegration overhaul is convenient, does not affect the discharge capacity of safety valve, take-off and returns seat.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, silencer cylinder, 2, dividing plate, 3, through hole, 4, upper cover, 5, hanger, 6, bearing, 7, base, 8, lower seal head, 9, suction port.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
1 describe by reference to the accompanying drawings, a kind of chemical plant of the present invention safety valve silencing apparatus, comprise silencer cylinder 1, dividing plate 2, through hole 3, upper cover 4, hanger 5, bearing 6, base 7, lower seal head 8 and suction port 9, described silencer cylinder 1 two ends are provided with upper cover 4 and lower seal head 8, described upper cover 4 is provided with hanger 5, described silencer cylinder 1 outer wall is evenly provided with through hole 3, described bearing 6 to be arranged on outside silencer cylinder 1 on lower side, described lower seal head 8 lower end is provided with suction port 9, described silencer cylinder 1 inside is provided with multiple dividing plate 2, and the opening of dividing plate 2 is not on the same line, it is cotton that described dividing plate 2 inside is filled with sound absorption, described through hole 3 is arranged in triangle or rectangular, described silencer cylinder 1 bottom is provided with base 7 and varies in size.
Specific works process: during use, noise enters silencer cylinder inside from suction port, and the opening of each dividing plate is different, upset the air-flow in silencer cylinder and sound wave, the sound absorption cotton of diaphragm internal also has the effect reducing noise, and last gas is got rid of from through hole, effectively reduces noise.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
