Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-pressure gas discharge, in particular to an exhaust silencing device for a high-pressure pipeline system. Background Art
[0002] The function of the exhaust muffler is to reduce the exhaust noise by gradually reducing the exhaust pressure and attenuating the pulsation of the exhaust pressure. For example, the ignition exhaust muffler is also called the boiler ignition exhaust muffler. The boiler exhaust muffler is mainly used for effective silencing of boiler steam emissions and other gas emissions in industries such as electricity, petroleum, chemical, metallurgy, and textiles. It is an important noise reduction device to eliminate the dynamic noise of steam emissions.
[0003] At present, most of the existing exhaust silencers are low-pressure silencers (discharge pressure is less than or equal to one MPa). This results in the low-pressure silencers being easily damaged by the impact force brought by the high-pressure gas when used in a high-pressure exhaust environment, causing slight deformation or damage, which affects the subsequent normal use and operation. At the same time, when used for high-pressure pipeline outlets, the outlet position may be frosted due to the fast gas flow rate, especially in low temperature weather, which is prone to ice blocking the exhaust hole and affecting the normal use of the device.
