Problems solved by technology

The existing mufflers also have the following disadvantages: the noise reduction is limited, generally below 30 decibels, most of the garbage is discharged into the air, causing pollution, and the garbage ejected may also hurt people
However, according to this structure, sometime

Embodiment Construction

[0017] Each part in the attached drawing:

[0018] 1 Shell 2 Box 3 Inlet porous pipe

[0019] 4 coaxial perforated pipe 5 spray water pipe 6 water spray port

[0020] 7 drain pipe

[0021] figure 1 Shown is the front view of the muffler of the present invention, figure 2 It is a partial cross-sectional view of the muffler of the present invention. It can be seen from the figure that the spray cooling exhaust muffler consists of an inlet porous pipe 3, a coaxial porous pipe 4, a spray water pipe 5, a water spray port 6, a drain pipe 7, a housing 1 and The box consists of 2. In the present invention, the shell and its internal structure can be called a pre-muffler, and the box body and its internal structure can be called a follow-up muffler. The inlet porous pipe 1 of the spray cooling exhaust muffler of the present invention is a horizontal pipe with the same pipe diameter as the pipe flushing system and holes in the pipe wall. One end of it is open, and the pipe end ha...

Abstract

The invention discloses a spraying, cooling and exhausting muffler, which is mainly used for treating noises and garbage in a pipe washing process. In the spraying, cooling and exhausting muffler, gases in a pipe washing pipeline are sprayed by fully utilizing a spraying water pipe arranged in a muffler. Because most of the gases in the pipe washing pipeline are high-temperature and high-pressure gases, once the gases are collided with sprayed cold water, the high temperature of the gases is heat-exchanged to the sprayed water and the cold water is heated and gasified; more heat is absorbed in the process of gasifying so that the temperature of the high-temperature gases in the pipe washing pipeline is reduced greatly; according to the principle of expanding with heat and contracting with cold, the reduction of the temperature of the gases causes the reduction of the volume of the gases, so that the pressure of the gases is also reduced; therefore, exhaust vent noises are reduced.

Description

technical field [0001] The invention relates to a noise elimination device, in particular to a pipe flushing noise reduction device used for controlling noise and garbage disposal in the pipe flushing process. Background technique [0002] The muffler can block the propagation of sound waves and allow airflow to pass through, which is an effective tool for noise control. There are many types of mufflers, but their muffler mechanism can be divided into six main types, namely resistive muffler, resistive muffler, impedance composite muffler, micro-perforated plate muffler, small hole muffler and active muffler . Resistive mufflers mainly use porous sound-absorbing materials to reduce noise. Fixing the sound-absorbing material on the inner wall of the airflow channel or arranging it in a certain way in the pipeline constitutes a resistive muffler. When the sound wave enters the resistive muffler, a part of the sound energy is converted into heat energy and dissipated in the ...
