How to deal with diesel generator muffler?

When a generator operates at 1,500 rpm, the Qingtian County Diesel Generator General Agent will produce a noise of 105 decibels one meter away from the unit. The general agent of Yunhe County diesel generator set will avoid noise in order to avoid noise. Apart from the engine room, Suichang County Diesel Generator General Agent Muffler Project should include the following links. ?

1. Disabling computer room inputs:

Each computer room has at least one input from the point of view of noise reduction, general agent of the diesel generator from Songyang County, Qingyuan County. Diesel There shouldn't be too many doors in the engine room. The general agent of diesel generator of Jingning She Autonomous County generally has one door, the general agent of diesel generator of Lishui County a small door, and the general agent of diesel generator of Lishui CountyGaochun should be as small as possible. Over 3 square meters, the structure is made of metal, with high-strength sound insulation materials attached inside. The exterior is made of metal iron plates, and the Peixian Diesel Generator General Agent Muffler Door is closely fitted to the wall and. Doorframe.

2. Silencing the Diesel Engine Air Intake System:

When the diesel engine is running, it must have enough air intake to maintain a normal running. Usually the air intake. The system should be set at the unit fan exhaust Directly opposite the inlet, according to our experience, the air inlet adopts the forced air inlet method. The inlet air passes through the muffler duct and is drawn into the engine room by the fan.

3. Diesel engine exhaust system silencer:

The diesel engineuses a water tank fan system for cooling. The water tank radiator should be vented outside the engine room to avoid. the noise must not propagate outside the engine room. The exhaust system is equipped with exhaust silencer ducts.

4. Silencing the diesel engine exhaust system outside the engine room:

Once the diesel engine exhaust air is denoised at through the exhaust silencer duct and discharged outside the engine room, there is always high noise, and the exhaust should be kept to a minimum through the silencer air duct installed outside of the computer room. The exterior of the silent air duct is a brick wall structure, and the interior is a sound-absorbing panel.

5. Diesel engine exhaust gas silencing system:

The exhaust gases emitted by the wordDiesel engines produce a certain amount of noise. We added a silencer box to the exhaust emission system. of the unit, and at the same time, for the exhaust gas silencer. The sound pipes are wrapped with flame-retardant rock wool materials, which can not only reduce the heat dissipation of the unit in the engine room, but also reduce the working vibration of the unit. unit, thus achieving the goal of attenuating noise.

First level of a large generator And how to make a secondary silencer... Let's talk about it in detail... It has to be professional... I agreed to give 300 points

The most basic way to reduce generator noise is to start from the sound source and use some conventional methods of noise reduction.noise reduction such as silencers, sound insulation, sound absorption, vibration isolation, etc.

1. Reduce exhaust noise. Exhaust noise is the main source of noise from the unit. It is characterized by high noise level, fast exhaust speed and difficult management. Using a special impedance complex, a properly fitted muffler can typically reduce exhaust noise by 40 to 60 dB(a).

2. Reduce noise from axial flow fans. When reducing generator cooling fan noise, two issues need to be considered. One is the allowable pressure loss in the exhaust channel. The second is the required amount of noise reduction. For both points above, resistive chip silencers can be used.

3. Acoustic insulation, sound absorption treatment and vibration isolation of the meeting roomchines

(1) Acoustic insulation of the engine room. After the unit's exhaust noise and cooling fan noise are reduced, the main source of noise remaining is electrical and mechanical noise. The method adopted is to remove all windows except the necessary interior wall observation windows connected to the observation room, all holes and holes must be sealed tightly, and the sound insulation of the brick wall must be greater than 40 dB (a). The doors and windows of the computer room adopt fireproof and soundproof doors and windows.

(2) Air intake and exhaust. After the sound insulation treatment of the computer room, the ventilation and heat dissipation problem in the computer room needs to be solved. The air inlet must be placed on the same straight line as the engine block and the air exhaust outlet. The air inlet must be equipped witha resistive piece silencer. Since the pressure loss at the air inlet is also within the allowable range, the air volume entering and leaving the engine room can be naturally balanced, and the ventilation and heat dissipation effect is obvious.

(3) Sound absorption treatment. All five walls of the engine room, except the floor, can be treated with sound absorption. According to the spectral characteristics of the drive unit, a perforated plate resonance sound absorption structure is used.

(4) Indoor air exchange and good sound insulation of the engine room will prevent the room air from convection when the engine unit is stopped, and the high temperature in the piece cannot be lowered over time. Low noise can be used. An axial flow fan coupled with a resistive chip silencer can solve the problem.

(5) Isolatedone vibration of unity. Before installation of the engine block, vibration isolation treatment should be carried out in strict accordance with the relevant information provided by the manufacturer in order to avoid long-distance transmission of structural noise and continuous radiation of airborne noise during propagation, making it impossible to obtain noise levels at the plant boundaries. For existing generator sets that require treatment due to exceeding standards, ground vibration conditions near the unit should be measured. If the vibration is obvious, the generator set should first be subjected to vibration isolation treatment.

In addition to noise-proofing treatment on the walls and top of the computer room itself, it is best to use the computer room door as a porch, which also serves for sound insulation and to noise reduction. . This is equivalent toTwo soundproof doors, plus a soundproof channel, as a secondary door. To silence the air, make an “impedance composite soundproof cover” at the air inlet and outlet. If the air inlet is in the porch, then realize. two soundproof covers, also called secondary soundproofing, surround the generator exhaust pipe, and connect two silencers in series. It is also a second level silencer. Let me explain in detail how to do this
