Abstract
The utility model relates to an outlet sound damper for screw compressor, which is the improvement of an existing sound damper. The main body of the outlet sound damper for screw compressor is in a cylindrate shape, and an inner core, a middle core and an outer core are arranged in the main body; the inner core, the middle core and the outer core are filled with high-density extra-fine glass wool, and are sprayed and coated with water-proofing agent; the outer core is also an outer shell, and an upper opening and a lower opening are elliptical sealing ends; cross brackets are welded in the sealing ends, playing the function of fixing the inner core and the middle core. The sound attenuating effect of the outlet sound damper for screw compressor can be kept in a stable state for a long time; the utility model has the advantages of convenient desintering, and convenient disassembly and assembly, and is suitable for the gas exhausting sound attenuation of a compression device in the field of soda ash, coal gas, petrochemical engineering, etc.
Description
The utility model belongs to the improvement of compressor air-discharging silencing apparatus.
General compressor and other machines in use all can produce noise in various degree, noise surpasses certain standard, the physical and mental health that will be unfavorable for operator, therefore corresponding apparatus in use often need be equipped with silencer, the screw compressor exit silencing apparatus is exactly the crucial match equipment of helical-lobe compressor, the agent structure of existing silencing apparatus is a cylindrical shape, and having interior filling to fill density is 10-15kg/m
3Inner core-body, middle core body and the external core of super glass wool form, external core is cylinder shell just, this silencing apparatus upper and lower opening has flat head, be welded with conical bracket in flat head, inner core-body and middle core body are installed with one heart, flat head is connected with steam outlet pipe under the last suction tude with flange again, such silencing apparatus can play certain noise elimination effect, but there is following deficiency, easily stops up fouling, noise elimination deleterious because conical bracket in use prolongs in time; Because fouling is serious, the cleaning difficulty; Must pull down cylindrical shell during cleaning, very little because top and the bottom are flat cover in the space, contact place of top and the bottom and miscellaneous part, so the dismounting space is little, brings difficulty to installation; The flat cover form structure does not meet the pressure vessel code requirement as calculated, has unsafe factor.
The utility model purpose provides a kind of screw compressor exit silencing apparatus that can overcome above-mentioned defective.
With reference to Fig. 1,2, the structure of the utility model silencing apparatus is such, agent structure is a cylindrical shape, in the tube inner core-body (1) of concentric installation, middle core body (2), external core (3) are arranged, external core also is a cylinder shell, and cylindrical shell has ellipse head (4) up and down, be welded with cross bearer (5) in the ellipse head, cross bearer is fixed on inner core-body, middle core body in the tube, fills the super glass wool of spraying water-proofing agent in inner core-body, middle core body and the external core, and its filling density is 20-40kg/m
3, the cylindrical shell upper and lower opening is connected with flange (6) with ellipse head, end socket again with flange and last suction tude with under the bend pipe of giving vent to anger be connected.
Water-proofing agent described in the utility model can adopt " 851 " waterproofing agent of organosilicon or waterproofing agent of organosilicon, " 851 " waterproofing agent of organosilicon primary coil is a sodium methyl silicate, easily be decomposed to form methane-siliconic acid, aggregate into the ventilative methane-siliconic acid ether of water insoluble energy then by weak acid; Waterproofing agent of organosilicon is the aqueous solution of organic silicic acid sodium, can breathe freely and can form filming of waterproof, and water absorption is not more than 2%.
The utility model screw compressor exit silencing apparatus owing to adopt ellipse head, meets the pressure vessel code requirement in use, has eliminated unsafe factor; The ellipse head of dismounting simultaneously time space is big, gives to install and pull down to clear up to bring convenience, and pulls down the related cross bearer of having pulled down of end socket, brings convenience for the cleaning fouling; Sound absorbing material adopts high density to fill the super glass wool of spraying water-proofing agent, the erasure effect that can maintain a long-term stability.
This silencing apparatus is applicable to the exhausting silencer of compression device in soda ash, coal gas, the field of petrochemical industry, as Roots blower, helical-lobe compressor, is specially adapted to the exhausting silencer of air and carbon dioxide helical-lobe compressor.
Description of drawings
Fig. 1 is the sectional view of the utility model silencing apparatus;
Fig. 2 is Figure 1A-A face plan view.
Embodiment
The cylindrical shell height is 1517mm, external diameter φ 1000mm, and external core internal diameter φ 790mm, middle core outside diameter φ 650mm, internal diameter φ 646mm, inner core-body external diameter φ 152mm, internal diameter φ 150mm, (being that the inner core-body wall thickness is 1mm), the ellipse head height is 331mm.The structure material is 1Cr18NiTi;
Sound absorbing material is the alkali-free super glass wool, and fiber diameter is less than 2mm, unit weight 4-15kg/m
3, acoustic absorptivity 〉=0.75;
Water-proofing agent adopts waterproofing agent of organosilicon, contains amount of solid about 35%, dilutes, dissolves, filters with 7-10 times of water before the water-proofing agent spraying, and the clear liquid per kilogram is sprayed on the 6-10m of super glass wool
2The surface on, spraying back airing or dry after roll filling, filling density is 20-40kg/m
3
The utility model silencer reduces noise 20-28dB when its erasure effect is than no muffler after testing after actual use the on the carbon dioxide helical-lobe compressor, more former silencer (actual measurement) reduces level of noise 10-17dB.
Claims (1)
1, a kind of screw compressor exit silencing apparatus, its agent structure is a cylindrical shape, in establish inner core-body, middle core body and the external core of filling super glass wool, the utility model is characterised in that and adopts ellipse head to be connected with the muffler body upper and lower opening with flange, in end socket, be welded with fixing in, the cross bearer of middle core body, in, in, the super glass wool spraying water-proofing agent of filling in the external core, its filling density is 20-40kg/m
