You might as well list where silencers are used in your factory and what are their practical effects? How different is it from not designing a silencer?
It is used for emptying each steam storage tank and for emptying each compressed air storage tank. Used for steam vacuum outlet.
We all add silencers to steam pipes. Without a silencer, the sound will be very loud and harsh. Even if there is no addition in the system, a buffer tank must be added to prevent fire.
Compressor stations, boiler stations, and pressure swing adsorption stations are all equipped with silencers, which greatly reduce noise and reduce unnecessary trouble.
Our factory has also installed a silencer at the entrance of the air blower, and the effect is pretty good.
Suppressor A suppressor is a device used to attenuate shooting noise. Generally, a silencer can only reduce the sound and make it as quiet as possible. The working principle of the silencer is mainly to make the projectile do work * * The gas releases heat energy in a closed space that is much larger than the barrel to reduce pressure and flow velocity and avoid excessive impact on the air near the muzzle (that is, muzzle noise - the main noise when a firearm is fired). The principle of the commonly used muffler in the world is basically to reduce the * * The speed and flow of gas rushing out of the muzzle reduce the maximum peak value to silence the sound. The specific measures are to install a number of silencer partitions or steel wires with small holes in the silencer, or to install a caliber-ratio gun at the muzzle. * * Small rubber silencers, etc. to reduce the maximum peak value of the muzzle (that is, to reduce the * * The work done by the gas is poured out), and at the same time, bullets below the speed of sound (low-velocity bullets) are used to reduce * * The whistling sound of flying in the air. No matter what method you use to reduce the sound of a gun, you always sacrifice some performance of the gun and make the automatic machine not work properly. Therefore, the silencer has no braking effect and will not reduce the recoil force. Today's firearms are generally equipped with a cage-type or barrel-type flame suppressor at the muzzle. By changing the cutting angle of the flame exhaust hole, a certain braking effect can be achieved, but the braking effect of the muzzle device after the silencer is installed also disappears. In addition to the usual silencer and flame suppression functions, the silencer also has an additional benefit - adding a weight at the muzzle, which can suppress the muzzle jump, reduce dispersion and improve accuracy.
Amberly silencer Amberly silencer points: Ignition exhaust muffler, safety valve exhaust muffler, turbine muffler, blowpipe muffler (Lianyungang Xinpu Anbaili Electric Power Auxiliary Machinery Factory) 1: Ignition exhaust silencer uses and product advantages Ignition exhaust silencer is also called boiler fire exhaust silencer. Boiler exhaust silencer is mainly used for effective silencing of boiler steam emissions and other gas emissions in electric power, petroleum, chemical, metallurgy, textile and other industries. It is an important noise reduction equipment to eliminate the dynamic noise caused by steam emissions. A muffler is a device that prevents the propagation of sound and allows air flow to pass through. The exhaust steam from various types of boilers is not only high temperature and high pressure, but also has a wide emission frequency band. To measure the quality of the exhaust muffler, the following three aspects should be mainly considered.: 1. The sound attenuation capacity of the muffler can meet the requirements of the "Noise Standard for Industrial Enterprises". 2. The muffler has good adaptability (design for different frequencies, temperatures and pressures). 3. The muffler has good structure (reasonable size, high strength and long life). Amberley brand boiler exhaust muffler is developed based on the composite silencing principle of resistance, spray and resistance. It has the advantages of large noise reduction capacity, adaptable frequency bandwidth, targeted design (low and medium pressure, high pressure, ultra-high pressure, subcritical, supercritical) and easy installation. 2. Principle of Ignition Exhaust Muffler The boiler exhaust muffler is mainly based on the "small hole injection" theory and the muffler principle of impedance expansion and sound absorption. Boiler steam emissions generally have fast flow speeds and high airflow noise. The flow needs to be expanded through through holes first. The steam after passing through multiple through holes is depressurized and flowed in the resistant expansion chamber. The airflow is then ejected through the small holes. After ejection, its octave frequency band The sound power has been reduced, and the frequency of the sound pressure level has been pushed up to a range of more than 20,000 Hz, and the noise has been greatly weakened. However, the secondary noise at some frequencies needs to be further silenced. We installed a resistive sound-absorbing cotton structure outside the expansion room. It is designed based on the spectral characteristics of the residual noise emitted by the pressure-reducing body to effectively absorb the residual noise. When the user installs it as required, the noise reduction amount can reach 30-42 decibels. Make it meet the requirements. 3. Ordering and Selection of Fire Exhaust Muffler The muffler produced by Amberly can only achieve the maximum sound attenuation effect if it is carefully designed according to the requirements of various emission parameters. Therefore, the following information must be provided when ordering an exhaust muffler.: (1) The amount of steam emission (T/h), pressure, and temperature. (2) Exhaust pipe diameter and wall thickness. http://www.ablfj.com/anbaili/cpzs.htm Blowpipe silencer 1. Purpose of blowpipe silencer The blowpipe silencer can be regarded as an integral part of the pipeline. After internal acoustic treatment, the generation and transmission of noise can be reduced. The design of the silencer for steam blowpipe cannot only consider the sound reduction effect. It should first meet the needs of steam blowpipe, that is, ensure the highest flow rate, minimum resistance, and maximum momentum as the premise, and then use pressure reduction, throttling, capacity expansion, and frequency shift silencing technology to reduce noise. Boiler blowing is the quickest and easiest way to eliminate debris engineering remnants in pipes: During the blowing process, a huge noise of about 130-150dB is generated. The PG-type blowpipe silencer can reduce the generation and spread of the noise, so that the outlet noise can be silenced to more than 30-40 decibels (A sound level), correspondingly the loudness is reduced by more than 60%, and the subjective feeling has obvious effects. It has been tried on the 600,000-kilowatt supercritical parameter unit of Guodian Changzhou Power Plant. There is no deformation of any component and no damage to the welds. ; The measured noise at a distance of 1m from the muffler complies with GB12348 "Noise Standard for Industrial Enterprises at the Boundary", and the noise reduction effect is better than similar products at home and abroad. 2. Characteristics of blowpipe muffler 1. In order to meet the requirements of high steam temperature during steam blowing of supercritical units, materials are selected for the inlet part of the blowpipe muffler and the first-level throttle tube.: 0Cr18Ni9, material selection for secondary throttle tube and shell: 20g or 16MnR. 2. Suitable for harsh working environments. The working medium may contain water, iron impurities (particle size up to ∮30mm), and engineering leftovers. 3. The noise reduction amount can reach 20dB~40dB(A). Applicable to (blowpipe method): Stabilizing blowpipe, pressure reducing blowpipe, oxygen adding blowpipe. 4. The technical regulations of GB150-1998 "Steel Pressure Vessels" must be followed when designing and manufacturing. In order to ensure the safe use of the muffler, the structure of the muffler must formulate and meet the measures and requirements for strength, differential expansion, displacement, hydrophobicity, rust allowance and prevention of being hit by blocky debris. The manufacturing quality of mufflers should be supervised and inspected by professionals from the design and competent agencies. 3. Blowpipe silencer ordering parameters When ordering PG type blowpipe silencer, the following information must be provided: 1. Blow pipe gas pressure and temperature. 2. Blow pipe diameter and wall thickness. 3. Emissions. This post was last edited by Haichuan Coal Chemical Industry on 2009-2-23 00:40 ]
Our factory has also installed a silencer at the inlet of the air blower, and the effect is pretty good. The harsh kicking sound before use is now only 30 decibels.
The function of the silencer is to silence and reduce noise. Mainly used in some high-pressure equipment and high-pressure pipelines, such as steam pipe network venting and safety pressure relief of high-pressure equipment.
It is convenient for everyone to operate and gives operators a good production and operating environment. Many people in the chemical industry are not very good at hearing, especially in compressed positions.
All levels of steam vent pipes and high and low pressure air vent pipes of air compressors in our factory are equipped with vent silencers.
Just take our factory as an example: The original design installed a silencer at the outlet of the blower, but the effect was average. ; After the technical transformation, some silencers were installed in the pressure swing adsorption process to prevent the loud noise caused by the gas passing through the pipeline when the pressure difference is large. The effect is good. ; A silencer is installed on the high-pressure venting pipeline to reduce the loud noise produced during the venting process, and the effect is average.
