Abstract
The utility model relates to a sound attenuation blimp, in particular to the double-layer sound attenuation blimp for a natural gas compressor. The sound attenuation blimp is divided into a top sound insulation region and a bottom sound insulation region. A sound attenuation slice global module is arranged inside the top sound insulation region and composed of a plurality of detachable sound attenuation slices, a top air outlet silencer and a compound sound absorption and insulation plate are arranged at the upper end of the top sound insulation region, air inlet silencers are arranged on the sides of the bottom sound insulation region, and an air cooler is arranged inside the bottom sound insulation region. On the premise that the air volume of the air cooler inside the blimp is met, air speed of an air inlet and exhaust sound attenuation channel is smaller than or equal to 10m/s. According to the design of the blimp, the whole noise reduction amount ranges from 20dB to 30dB, so that in a skid-mounted type CNG refueling station provided with the double-layer sound attenuation blimp, when devices of the CNG station are operated, noise at the position which is 7 meters away from the blimp can be lower than 75dB (A).
Description
Technical field
The utility model relates to a kind of sound-insulation cover, relates in particular to a kind of double-deck sound-insulation cover for natural gas compressor.
Background technique
Compressor is a kind of strong noise equipment, is a kind of main man-made noise pollution sources.Along with the development of Compressor Technology level and continually strengthening of performance index, the noise problem of compressor has become the important research topic of compressor industry.
The Main Noise Sources of prying gas compressor bank is the mechanical noises such as cooling fan noise, compressor operating noise, motor.The suitable major part of the noise of compressor is produced by compressor operating.Fan noise is periodically to hit air particle by the blade that rotates, and causes that the pressure pulsation of air produces noise, and being used for cooling fan is important noise source.
Mechanical noise is that the equipment moving parts rotatablely move and produce.This type of compressor bank has two characteristics: 1. power is larger, and the noise pollution of generation is serious; 2. equipment operation and heat radiation need a large amount of air ventilation, need to arrange larger ventilated port.Ventilated port often when solving ventilating problem, has also brought strong noise to reveal, and by ventilated port, the strong noise of equipment is hardly through the surrounding enviroment that are radiated of decay.

The utility model is skid-mounted CNG gas station acoustic hood, and cover body is arranged at the bottom of the CNG gas station on the sled framework, the inner gas compressor set of installing.Acoustic hood is detachable assembled structure, and outward appearance is determined color matching system according to professional technological esthetics design principle.Overall structure is equipped with the compound sound absorption module of high noise insulation factor; High noise insulation factor soundproof door module; Advance, the air exhausting soundproofing module; Visual, detachable access path module; The natural gas line external connector module; The interior lighting system.The whole noise reduction of acoustic hood ≮ 30 dB.
At first acoustic hood installs steel structure frame on the sled framework at the bottom of the CNG gas station, adopt square steel to make, and brushes one priming paint, and the twice rust proof paint carries out preservative treatment.
The compound sound absorption module of high noise insulation factor, adopt the MULTIPLE COMPOSITE structure, thickness 90 ~ 100mm, fastening overlap joint splicing structure in module adopts, according to the demand of CNG gas station different model product, can be divided into carbon steel outside plate sound absorption module, the outer sound absorption module of corrosion resistant plate.
The beneficial effects of the utility model:
1, the utility model is normal maintenance and the replacing of assurance equipment, and the acoustic hood front arranges the sound insulation access door, and soundproof door is equipped with opens positioning work piece, closes the chucking handle, integral sealing means, acoustics specialty door lock.
2, the utility model satisfies under the prerequisite of air cooling device air quantity in cover, advances, air exhausting soundproofing channel wind speed ≯ 10m/s.
3, the whole noise reduction of the utility model acoustic hood design is 20`30dB.
4, skid-mounted CNG of the present utility model gas station is installed when equipment moves, can be lower than 75dB (A) from seven meters noises of acoustic hood.
