Description

Technical Field

[0001] The utility model relates to the relevant field of mufflers, in particular to a sootblowing muffler. Background Art

[0002] A silencer refers to a noise reduction device that can be used for air flow ducts that also have noise transmission, such as pipes and elbows with sound-absorbing linings, or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance, to attenuate or reflect the noise in the duct. The former is called a resistive silencer, and the latter is called a reactive silencer. There are also impedance composite silencers. There are many types of silencers, but according to their silencing mechanism, they can be divided into: resistive silencers, reactive silencers, impedance composite silencers, micro-perforated plate silencers, small hole silencers and active silencers.

[0003] There are still certain drawbacks in the use of pipe silencers in the prior art. Traditional silencers usually only have the function of sound attenuation and noise reduction. Since the flue gas discharged into the atmosphere contains a certain amount of ash, the ash is easily adsorbed on the silencer plate, causing the silencer holes to be blocked, affecting the silencer effect and making it inconvenient to clean the ash. Utility Model Content

[0004] The purpose of the utility model is to provide a sootblowing silencer to solve the problem that the traditional silencer proposed in the above background technology usually only has the function of silencing and reducing noise. Since the flue gas discharged into the atmosphere contains a certain amount of ash, the ash is easily adsorbed on the silencer plate, resulting in the silencing holes being blocked, affecting the silencing effect and making it inconvenient to clean the ash.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sootblowing silencer, comprising a pipeline silencer and a sootblowing slag cleaner, an ash separator is provided inside the sootblowing slag cleaner, an ash collecting trough is provided at the bottom of the ash separator, interfaces are provided at obliquely lower positions on both sides of the ash collecting trough, a filter plate is provided above the inside of the ash separator, a sealing cover is provided at the top of the ash separator, inspection ports and air inlets are provided on both sides of the sootblowing slag cleaner, an ash discharge port is provided at an obliquely lower position on the front end of the sootblowing slag cleaner, the pipeline silencer is provided above the sootblowing slag cleaner, a fixed bottom plate is provided at the bottom end of the pipeline silencer, a silencer plate is provided inside the pipeline silencer, and an air outlet is provided at the rear end position of the top of the pipeline silencer.

[0006] In a further embodiment, the ash discharge port is plug-connected to the ash collecting trough via an interface, and the cross-section of the ash collecting trough is set to an inverted trapezoidal structure.

[0007] In a further embodiment, both ends of the ash separator are fixedly connected to the inspection port and the air inlet through an assembly mounting head and an assembly mounting groove, a sealing ring is provided at the end of the assembly mounting head, and the sealing ring is connected to the assembly mounting head by mounting.

[0008] In a further embodiment, three connecting pipes are provided on the top of the sealing cover, the ash separator and the pipe silencer are connected to the plug-in port through the connecting pipes, and the pipe silencer and the soot blower and slag cleaner are fixedly connected by bolts.

[0009] In a further embodiment, the sealing cover is fixedly connected to the ash separator by means of hexagon socket fixing bolts, and the ash separator is fixedly connected to the soot blower and slag cleaner by means of a bracket.

[0010] In a further embodiment, support legs are provided at both ends of the bottom of the soot blower and slag cleaner, and the cross-section of the soot blower and slag cleaner is set to a U-shaped structure.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the soot blower and slag cleaner are installed as a whole with the pipeline silencer, so that the silencer has two functions of sound reduction and noise reduction and soot blowing and slag cleaning. An ash separator is arranged inside the soot blower and slag cleaner. When the flue gas in the pipeline enters, the gas and ash in the flue gas can be separated by the ash separator. The separated ash can be directly recovered in the ash collecting trough and discharged from the ash discharge port. The ash cleaning process is simpler and more labor-saving, and the ash can be prevented from being adsorbed in the silencer hole, thereby extending the service life of the silencer plate and being easier to operate.
