Vapour Exhaust Muffler for Steam Processing Plants
Description：Vapour Exhaust Muffler for Steam Processing Plants - China Mufflers and Exhaust Muffler
The steam muffler is mainly used for the effective silencing of boiler steam emission and other gas silencing emissions in electric power, petroleum, chemical industry, metallurgy, textile and other industries. It is an important measure to eliminate steam emission noise. All kinds of boiler exhaust steam not only has high temperature and high pressure, but also has a wide emission frequency band. To measure the quality of steam exhaust muffler, the following three aspects are mainly considered:
3. The muffler has good structure (reasonable size, high strength, long service life and convenient installation).
1,Introduction of JSTK Steam Muffler
The small hole muffler is composed of a straight pipe with a closed end and a shell, and many small holes are drilled in the pipe wall and shell. The principle of orifice muffler is based on the frequency spectrum of jet noise. If the total area of the nozzle is kept unchanged and many small nozzles are used instead, when the airflow passes through the orifice, the frequency spectrum of jet noise will move to high frequency or ultra-high frequency, which will obviously reduce the audible sound components in the frequency spectrum, thus reducing the interference and harm to people.
Small hole muffler has the advantages of simple structure, light weight and convenient installation.
Installation mode of small-hole muffler: Because of its light weight, small-hole muffler only needs to weld pipes or connect them with flanges when installing
2,Introduction to new high efficiency I(JSTB) steam muffler
The new high efficiency type I muffler refers to a muffler that properly combines sound absorption and acoustic reflection. The noise transmitted along the pipeline is attenuated with distance, and at the same time through the noise in the cross-sectional area of the pipeline, the sound waves of certain frequencies transmitted along the pipeline are reflected back in the direction of the sound source at the mutation, so as to achieve the purpose of silencing.
The new high efficiency type I muffler is an effective combination of dilated muffler and impedance sound absorbing material through an appropriate structure. It can effectively eliminate low, medium, and high frequency noise.
The installation of the new high-efficiency type I muffler is very simple. The branch ear or base is bolted to the corresponding position and the pipe is connected(welding or flange connection).
3,Introduction to New High Efficiency Type II(JSTA) Steam muffler
The new invention patented muffler is a new type of structural muffler developed by our company. The shape structure is similar to that of ordinary compound muffler. The difference is that the bottom of the muffler is equipped with the heat absorption displacement device developed by my company.It can effectively prevent the vibration of equipment caused by the displacement of the pipeline.4,Order parameters of steam muffler:
