Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of papermaking equipment, and in particular to a steam exhaust pipe silencing device and a steam pipeline for papermaking. Background Art
[0002] With the development of the national economy and the improvement of people's living standards, the country has attached more and more importance to environmental protection and has issued a series of environmental protection policies, with control requirements for wastewater, waste gas and noise. In particular, the country has attached more and more importance to noise in recent years. Paper mills are high-energy-consuming enterprises, which will inevitably produce some noise, which needs to be controlled.
[0003] At present, the steam used in paper mills is mainly used for heat dispersion of pulp and paper making, heating of drying cylinders and other equipment. The pressure is generally controlled at 6-8bar. If the pressure exceeds this, it will affect the operation of the equipment. Usually, a temperature reduction and pressure reduction device is installed on the steam pipeline to control the pressure. Sometimes, the steam pressure suddenly rises (such as paper machine paper breakage), exceeding the capacity of the temperature reduction and pressure reduction device. Therefore, a safety valve is installed on the steam pipeline after the temperature reduction and pressure reduction device. When the steam pressure exceeds a certain pressure value, exhaust and pressure reduction will be carried out. However, the noise generated by the exhaust of the steam safety valve is particularly loud, which affects the physical and mental health of employees.
[0004] Therefore, the industry urgently needs to improve the steam pipeline system, reduce noise, and protect the physical and mental health of employees. Utility Model Content

In addition, the utility model also relates to a steam pipeline for papermaking using the silencer, which has the characteristics of low noise and low cost.
[0025] The silencer device 100 includes a silencer housing 1, a water tank 2 and a drain pipe 12. The silencer housing 1 is provided with an air inlet 11, the air inlet 11 is connected to an air inlet pipe, one end of the air inlet pipe is connected to a steam exhaust pipe, the water tank 2 is used to store buffer water and is built into the silencer housing 1 with a gap therebetween, the top of the water tank 2 is connected to the other end of the air inlet pipe, and the drain pipe 12 is provided at the lower end of the silencer housing 1 and is used to discharge the buffer water overflowing from the water tank 2 into the gap.
