Abstract
The utility model relates to a high-sound strong sound wave generator, which comprises an impact whistle and a base tube, wherein, the base tube is arranged vertically to the impact whistle and is communicated with a resonant cavity of the impact whistle; one side of the base tube is provided with an end cover; a rotary cork is movably inserted in the base tube through the end cover; the other end of the base tube is connected with an acoustic duct through a connecting flange; the base tube and the impact whistle are arranged outside a furnace body. After the acoustic duct is added, the radiation condition of acoustic waves is improved, and the acoustic intensity of the acoustic waves of dust removing of the impact whistle is greatly increased, which increases the acoustic pressure level thereof. When the utility model is in use, the impact whistle does not need to be arranged in the furnace body and can avoid thermal deformation; due to the increased intensity of the acoustic waves, close-packed installation can be omitted, and gas consumption can be reduced.
Description
The utility model relate to a kind of from the combustion chamber device of dust out, especially a kind of high sound intensity sonic generator that has the impact whistle of acoustic conducting pipe.
At present, impact the whistler wave ash disposal and in boiler running process, be used widely, because employed impact whistle audible frequency concentrates on middle and high frequency, frequency is single, and intensity of acoustic wave is difficult to improve, and sphere of action is little, ash disposal is not thorough, only is applicable to medium and small ash disposal space; And need be installed in the stove, easy deformation when high temperature, and wash away and damage because of constantly being subjected to high velocity air; Because the restriction of the sound intensity, the acoustic wave energy decay is big, therefore needs intensive installation, and air consumption is big; On chemical engineering industry because the sound wave flow velocity is fast, when installing in the stove with the heat-exchange tube distance closely, heat-exchange tube is had souring, influence chemical process.
The purpose of this utility model is to provide a kind of can significantly improve intensity of acoustic wave, avoids thermal deformation, the high sound intensity sonic generator that air consumption is little.
The utility model high sound intensity sonic generator, comprise and impact the whistle, wherein also be provided with a parent tube, described parent tube and vertical setting the in the described impact whistle, and communicate with the resonant cavity at the described impact whistle, a side of described parent tube is provided with end cap, and cock is inserted in the parent tube by described end cap versatilely, the other end of described parent tube is connected with acoustic conducting pipe by adpting flange, and the described parent tube and the described impact whistle place the outside of body of heater.
Improvements of the present utility model are that described acoustic conducting pipe is taper.
Another improvements of the present utility model are that described acoustic conducting pipe is the index shape of satisfying following formula,
Y=R
0e
X/hWherein: Y is the curve of acoustic conducting pipe tube wall;
R
0Be throat radius;
X is the length of acoustic conducting pipe center line;

An improvement part more of the present utility model is to be provided with screw thread between described cock and the end cap, is being sealed and matched of sliding between cock and the parent tube.
An also improvement part of the present utility model is to be between the described parent tube and the impact whistle and between parent tube and the adpting flange welding.
After advantage of the present utility model and good effect are to add acoustic conducting pipe,, its sound pressure level is increased because the improvement of acoustic irradiation condition has significantly improved the sound intensity that impacts whistle ash disposal sound wave.During application, impact the whistle and needn't be installed in the stove, avoided thermal deformation, because the increase of intensity of acoustic wave need not intensive installation, air consumption reduces.Thereby the reliability of impacting the whistle is greatly improved, has reduced the requirement of material, it is convenient to change.
