      Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers. The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      Blower is a kind of machinery used for gas transmission, and its main function is to convey air volume. The role of the blower is to assist combustion and ventilation. Different types of blowers will have different effects.

      Roots blowers use two 8-shaped blades, and their clearance is very small. The squeeze of the two blades squeezes the gas to the outlet. Among them, the special fan for printing paper is used to transport paper by gas; CK-L series Roots blower is used in power, petroleum, chemical and other industries.

      The centrifugal fan uses curved air blades, and the gas is thrown out of the casing by centrifugal force. The general induced draft fan for industrial boilers is used in large boiler rooms, metallurgy and other industries; explosion-proof centrifugal fans can be used for ventilation and exchange of volatile gases.

      Therefore, the diversification of blowers results in diversified blower functions.

      Harm of Boiler Blower Noise and Its Prevention

      1. Harm of environmental noise pollution

      The impact and harm of noise on the human body can generally be divided into two aspects: labor protection and environmental protection. The former refers to endangering human health and causing various diseases. The latter refers to disturbing the quiet environment and affecting people's normal work and life. The harm of noise to human health is mainly manifested in: damage to hearing, causing noise-induced deafness; leading to cerebral cortex excitement and balance imbalance, cerebrovascular function damage; damage to the system, causing digestive disorders; interference to people's normal life, rest, language conversation and daily life Work learning, distracting and reducing work efficiency.

      2. Basic principles of noise management

      There are three main factors that contribute to noise pollution: sound sources, media, and receivers. Only when these three exist together, can the Tianjin centrifugal fan interfere with the listener. Starting from these three aspects, the purpose of controlling noise can be achieved by reducing the sound source, limiting the transmission of noise, and blocking the reception of noise. In specific noise control technologies, three types of sound absorption, sound insulation, and noise reduction can be used. Measures.

      2.1 sound absorption

      When sound waves are incident on the surface of an object, part of the sound energy is absorbed by the object and converted into other forms of energy, which is called sound absorption. The sound absorption performance of a material is expressed by the absorption coefficient. The larger the sound absorption coefficient, the better the sound absorption performance of the material. The sound absorption performance of a material is related to the material's properties, structure, angle of incidence of sound waves, and frequency of sound waves. The sound absorption mechanism of porous sound absorbing materials is: there are numerous small holes in the material that penetrate through each other. When sound waves are incident on the surface of these materials and then into these small pores, the air movement in the pores is caused to abut The air on the wall of the hole and the surface of the fiber is difficult to move due to friction and viscous motion resistance, so that the sound energy is converted into heat energy and consumed. Therefore, sound-absorbing materials with good performance must be porous, and the holes must be connected with each other, and the through holes must communicate with the outside world so that sound waves can enter the material.

      For example, the sound absorption coefficient of a 10cm-thick ultra-fine glass wool is 0.87 for a 1000 Hz sound wave.

      2.2 Sound insulation

      The method adopted for sound insulation is to close the noise source so that the noise is controlled in a small space. This sound insulation structure is called a sound insulation cover. When the sound wave encounters the shield, due to the change in the characteristic impedance of the interface, part of the incident sound energy is reflected, part is absorbed, and part of the sound energy penetrates the shield and continues to propagate. The sound insulation performance of a material can be expressed by the sound transmission coefficient. The smaller the sound transmission coefficient, the less the sound energy transmitted through, and the better the sound insulation performance of the material. The sound insulation performance of a material is related to the structure and properties of the sound insulation body and the frequency of the incident sound wave.

      2.3 Silence

      Sound reduction is to fix the porous sound-absorbing material on the inner wall of the airflow channel or in a certain way to achieve the purpose of reducing aerodynamic noise. The amount of noise reduction can generally reach 10-50 decibels.

      3. Fan noise management technology

      The noise of the blower and induced draft fan in the boiler room is generally around 90 decibels. Because the temperature of the boiler flue gas being conveyed is as high as 180 ° C, the use of closed sound insulation can cause poor heat dissipation, excessive motor temperature, and even burn the motor. Therefore, in the process, the fan noise reduction and energy saving are combined. Through practice, the comprehensive control plan for energy saving and noise reduction of boiler fans is as follows: keep the process layout of the boiler room unchanged, place blowers and induced draft fans in sound insulation rooms, connect them to the host with ventilation pipes, and place them on the top of the sound insulation room. An air inlet is installed on the top or wall, and a muffler is installed for air intake in the machine room. In the plan layout, place the blower close to the side of the boiler room, the air inlet is on the upwind side, and the motor is placed in the middle of the air flow channel. When the boiler is running, due to the negative pressure generated by the blower in the sound insulation room, a large amount of outdoor fresh air will automatically enter the sound insulation room. First, the heat exchange with the induced draft motor will cool and cool the room, and the indoor temperature will be maintained at about 50 ° C.

The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      Centrifugal blowers can be used as indoor ventilation for general factories and large buildings, to transport air and other non-self-igniting, harmless to humans, and non-corrosive gases to copper. Techtronic centrifugal blowers have the characteristics of small size, light weight, simple operation and strong refrigeration effect, which create a good environment for industrial production.

      Small size and light weight: The single machine has a large cooling capacity. When the cooling capacity is the same, it has a small volume, covers a small area, and is 5 to 8 times lighter than a piston type. The cooling capacity can be adjusted economically and conveniently with a large adjustment range.

      Simple operation: Because it has no vulnerable parts such as steam valve piston rings and no crank link mechanism, it has reliable operation, stable operation, low noise, simple operation, and low maintenance costs. There is no friction between the work wheel and the casing, no lubrication is required. Therefore, the refrigerant vapor does not contact the lubricating oil, thereby improving the heat transfer performance of the evaporator and the condenser.
