1、 Product overview and composition series:
Small hole injection silencers are mainly used in power plants, thermal power companies, petroleum, chemical, steel, metallurgy, paper, printing and dyeing, textile and other industrial and mining enterprises. The muffler is composed of multi-stage and different cylinders. The exhaust gas is injected into the atmosphere through the acoustic shell with evenly distributed holes in the outermost layer after the primary and secondary expansion and depressurization of the inner cylinder. TEG steam exhaust muffler is suitable for the exhaust of steam equipment in boiler, steam turbine, steam generator, steam pipe network and many other thermal systems. It is mainly divided into PA series steam safety valve and exhaust valve, release valve, pressure relief valve exhaust exhaust exhaust muffler; PD series low-pressure steam exhaust exhaust muffler, its subseries are PDY series high-pressure deaerator exhaust muffler, PDB series back pressure turbine exhaust exhaust muffler; Pb series start-up fire to air exhaust muffler.
2、 The features of small hole injection muffler are as follows
The small hole injection muffler is a special equipment which can block the sound transmission and let the air flow through smoothly and prevent the aerodynamic noise. It is reasonable and compact in structure. It has the advantages of small volume, light weight, high strength, convenient installation and maintenance. It is an effective noise elimination equipment for controlling exhaust emission noise. The noise attenuation value is 32-45db (a). The emission standard is in line with the national hygienic standard for noise of industrial enterprises.
3、 Material selection of small hole injection muffler:
Small hole injection muffler and acoustic shell are made of stainless steel. The connecting pipe is determined according to the steam condition of the equipment. The three commonly used nozzle materials are 20 ? carbon steel, 304 (0Cr18Ni9), 321 (1Cr18Ni9Ti / 0Cr18Ni10Ti) stainless steel and alloy steel pipe suitable for high temperature and high pressure.
4、 Application scope of small hole injection muffler:
Installation nozzles: DN25, DN50, DN65, DN80, DN 100, DN 125, DN 150, DN200, DN250, DN300, DN350, dn400, dn450
Steam condition: steam temperature: 104 ℃ - 540 ℃, steam pressure: 0.5-13.83mpa
There are many kinds of steam emission objects of thermal equipment. Our company can design and manufacture the noise reduction equipment which can meet the operation parameters according to the exhaust steam volume, steam pressure level, steam temperature and nozzle size. Customized combined steam exhaust muffler.
