The new type of highly efficient anti-spray and resistance series muffler equipment has a wide range of applications. It is used for noise reduction and sound insulation in automotive mufflers and other equipment. This series of mufflers is developed based on the principle of anti-spray and resistance composite noise reduction, featuring large noise reduction, small size, light weight, easy installation and no maintenance. The noise reduction frequency characteristics of the muffler. The anti-spray and resistance type muffler has excellent noise reduction effects on various frequencies.
The applicable wind speed of the muffler is generally 6-8m/s, and should not exceed 12m/s at the maximum. At the same time, pay attention to the pressure loss of the muffler. The installation of mufflers and other noise reduction equipment must have independent load-bearing suspension rods or bases; they should be connected to the noise source equipment through flexible joints. When two muffler elbows are used in series, the connection distance between the two elbows should be greater than 2.5 times the diagonal length of the elbow section.
For high-temperature, high-humidity, oily, and steamy environments, micro-perforated structure noise reduction equipment is generally selected. For environments with cleanliness requirements such as operating rooms, recording studios, and clean workshops, micro-perforated structure noise reduction equipment should be used.
When adjacent rooms are connected through pipelines, pay attention to the mutual influence of indoor noise through the pipelines. If necessary, the air outlets should be treated for noise reduction.
Fan mufflers are divided into: centrifugal fan mufflers, Roots fan mufflers, blower mufflers, and axial fan mufflers. Fan mufflers are mainly used to reduce the aerodynamic noise at the air outlets, air ducts, and intake ports of various fans.
Steam mufflers are divided into: TA type steam safety valve mufflers, TD type low-pressure steam mufflers; exhaust mufflers are divided into: boiler exhaust mufflers, steam turbine exhaust mufflers, safety valve exhaust mufflers, ignition exhaust mufflers, TB type ignition exhaust mufflers, ZB type vacuum pump exhaust mufflers; boiler mufflers are divided into: boiler exhaust mufflers, ignition boiler exhaust mufflers, and steam turbine exhaust mufflers.
The steam turbine exhaust muffler can be used for back-pressure, extraction-back-pressure, pure condensing, extraction-condensing, and industrial drive steam turbine exhaust noise reduction. This type of muffler not only has a certain noise reduction capacity but also ensures that the steam turbine pressure does not increase during use. This type of muffler has been used in many power plants for a long time and has received excellent feedback. It has also been strongly recommended and recognized by the East China Electric Power Design Institute. Our factory is also a professional manufacturer of this type of muffler.
The boiler exhaust muffler is mainly used for effective noise reduction of steam and other gas emissions from boilers in power, petroleum, chemical, metallurgical, textile and other industries. It is an important measure to eliminate steam emission noise. Various boiler exhaust steam not only have high temperature and pressure but also have a wide emission frequency band. The performance of the steam emission muffler is measured by this.
