The new high-efficiency anti-jet resistance series muffler equipment is widely used in power generation, chemical industry, metallurgy, textile and other industrial factories and mines for the muffling and sound reduction of various types of boilers, steam engine exhaust; fans; safety doors and other equipment. This series of muffler is developed according to the principle of composite muffling of resistance, spraying and blocking, which has many advantages such as large muffling volume, small volume, light weight and easy installation without maintenance.
1.TA type steam safety valve muffler for various types of steam safety valves
Applicable to power station boiler PCV/ERV safety valves (power release valves), pot safety valves and superheater safety valves, reheater safety valves, and other pressure devices such as the safety valve. Its steam venting should be avoided not only to avoid excessive noise, but also to let the steam flow smoothly discharged without affecting the displacement of the safety valve, jumping and back to the seat, for this reason, the previous common multi-stage throttling and small holes injection muffling means of sound reduction that is not suitable for the use of this limitation has always been the design of the safety valve muffler difficult, but also the safety valve muffler muffling effect of the reason for the poor. The new type TA safety valve exhaust muffler for safety valves adopts the spray impedance composite muffling principle, in which the large hole expansion replaces the smaller diameter flow control hole, and the resistant and resistive muffling and noise reduction mechanism is strengthened structurally, so as to achieve the muffling and noise reduction effect with higher safety coefficient.
2. TB-type ignition exhaust muffler for boilers and other steam equipment
TB-type boiler ignition exhaust muffler is designed by integrating the most reasonable muffling principle of PB-type exhaust muffler. High-pressure steam in the muffler after a flow control into the pressure-reducing body, after a large volume expansion again after the pressure reduction, thus forming a low-pressure steam after the spray, in the process, part of the internal energy of the steam flow into a certain frequency of acoustic energy, and its noise, although the power is greatly weakened, but often due to the exhaust deviation from the design value of the exhaust steam for a number of reasons, so that the exhaust noise is still higher than the standard value. For this reason, a combined multi-material composite structure of sound-blocking and sound-absorbing cover is designed outside the pressure-reducing body. The composite sound-blocking and sound-absorbing cover is designed according to the spectral characteristics of the residual noise emitted from the pressure-reducing body, which is used to effectively absorb the residual noise. When the user installs it according to the requirements, the total muffling amount can reach 36～42dB.
3. TD-type low-pressure steam muffler applicable to all kinds of low-temperature and low-pressure thermal devices
There are a large number of low-pressure boilers of 0.13Mpa and below used in industrial and mining enterprises, and there are also a large number of low-pressure thermal devices in the thermal system of power stations, such as back-pressure turbine, deaerator, auxiliary extractor, steam turbine oil pumps, boiler continuous sewage discharge, periodic sewage discharge, etc. The above equipment is required by the steam discharge pipe. The above equipment according to the requirements of the exhaust vapor pipe, configure lightweight structure, more convenient installation of the muffler. For different muffling objects, there are special TDb-type back-pressure turbine exhaust mufflers, TDy-type deaerator mufflers and other series of muffling and sound-reducing products, which can meet the requirements of users.
4.TC-type special muffler for pipe flushing after boiler trial blowing and industrial pipeline installation and maintenance
TC-type pipe flushing muffler is a kind of special exhaust muffler and noise reduction equipment developed to reduce the noise generated by debris discharged from the outlet of the flushing pipeline and the exhaust gas discharge during the trial blowing of the boiler in the power station. It can also be used for other industrial pipelines and civil pipelines to eliminate noise and debris after installation or maintenance.
5. PB series of small-hole injection muffler for pipeline gas emission
PB series of small-hole injection muffler is a new generation of noise reduction products developed in the nineties, which is based on the principle of small-hole bucking injection muffler, through the optimization of the design, the noise reduction index, safety performance and service life are far superior to the similar products on the market, and it can meet the requirements of electric power, metallurgy, petroleum, chemical, textile, papermaking, paper making and other industrial pipelines.
The noise reduction of various boilers, pressure vessels, pipelines and their safety valves and release valves in low pressure, medium pressure, sub-pressure, high-pressure, ultra-high pressure, sub-critical parameters can better meet the noise reduction needs of low-pressure, medium-pressure, sub-high pressure, ultra-high pressure, sub-critical parameters of boilers, pressure vessels, pipelines and their safety valves and release valves.
6, suitable for ventilation ducts with CF-type fan silencer
Fan is a kind of general mechanical equipment, the use of a wide range of electric power, mining, machinery, metallurgy, chemical industry and other industries are inseparable from the production of fans. Fan in the operation of the noise generated by the often become a health impact on workers and interference with the environment of the scourge. Especially near the living area of the fan, its air inlet and outlet of the radiation of aerodynamic noise, is the main factor of environmental pollution, the formation of a public health hazard, is one of the main objects of our industrial sector to combat noise pollution.
7, suitable for diesel generator exhaust muffler with CP-type diesel generator exhaust muffler
Diesel generator with its good economic and power performance, is widely used in industrial and mining enterprises in production and operation, because of its operation process emissions contain a certain amount of smoke (that is, we often see black smoke), the phenomenon is due to incomplete combustion of fuel and produced. The phenomenon is due to incomplete combustion of fuel. Therefore, conventional ventilation mufflers, such as microporous plate mufflers and mufflers with sound-absorbing fillers are never desirable if they are used in such environments, because they can only play a momentary muffling and sound reduction.
8, used for ventilation pipe with XB-type ventilation pipe muffling and sound-absorbing sheet
XB-type ventilation pipe muffling and sound-absorbing sheet is a resistive muffling and sound-absorbing sheet, when the sound wave passes through the pipeline lined with sound-absorbing material, the sound-absorbing material consumes the energy of the sound wave, so as to achieve the effect of noise reduction; the muffler of this series is designed through optimization, and the use of new type of attraction auxiliary lining material, so as to increase the amount of sound elimination.
9, used for equipment muffling and sound insulation with industrial sound-absorbing acoustic enclosure
Sound-absorbing acoustic enclosure application is quite wide, fans, pumps, and other types of sound source equipment, and so on, a lot of sound source management will be applied to the sound-absorbing sound-absorbing products. Its main design principle is the propagation of sound waves from the path of the noise source for effective management. Due to the external dimensions of each type of sound source equipment, ventilation and heat dissipation requirements are different, so often it needs to be designed according to the site sound source processing production.
