Abstract
The utility model discloses an environment-friendly sound wave generator which is composed of a catheter for sound waves, a core bar, a spraying mouth chamber body and a resonant chamber cover, wherein the core bar is fixed at a shaft line position in the catheter for sound waves, a spraying mouth chamber is formed between the back part of the core bar and an inner chamber of the spraying mouth chamber body, and an air outlet of the spraying mouth chamber is positioned in an annular slot between a circular bottom edge of a circular cylinder body of the core bar and the front end of the spraying mouth chamber body; the front end of the core bar is fixedly connected with the resonant chamber cover, and an outlet of the resonant chamber cover is positioned at the edge of a resonant chamber; a resonant chamber body is formed between the back part of the catheter for sound waves and the outer wall of a conical table of the spraying mouth chamber. The utility model has the advantages of obviously improved sound pressure level, wide range of frequency, long acting distance without directionality, little air consumption, selective working media (compressed air or high-pressure steam), convenient installation and maintenance without corrosion for equipment and ash clogging phenomenon when installed outside a stove.
Description
Technical field
The utility model relates to the boiler online ash removal device that utilizes ultrasonic dedusting technology to make.
Background technology
At present, sale mainly is medium-high frequency sonic generator (a Hartmann oscillator sonic generator) with the sonic generator that often is applied to the boiler online ash removal on the market.The shortcoming of this sonic generator is the scope of effect little (an only distance about 1 meter), and directive property is very strong, and sound field is spindle and distributes, and sound pressure level is low, about 140dB; Install in the stove, washed away by high-temperature flue gas stream and corrode, easily stifled ash, damage can't be keeped in repair; Air consumption is big, because of on-the-spot compressed air can't satisfy supply, and can only use HCS.
Summary of the invention
The purpose of this utility model provides a kind of environment-friendly type sonic generator, and is little to solve the sound wave sphere of action, and directive property is crossed strong and technical problem such as air consumption is big.
Environment-friendly type sonic generator described in the utility model is made up of acoustic waveguide tube, core bar, spout cavity and resonant cavity cover; Described acoustic waveguide tube is by anterior horn section, and rear portion cylindrical portions may and rear end flange connecting dish are formed; The inner tube wall of described spout cavity is the second order ledge structure, is by the gas trend and dwindles shape, and its outer tube wall is to be circular cone shape, and the spout cavity is connected with the rear end of acoustic waveguide tube by hickey; Described core bar is fixed in the axial location place in the acoustic waveguide tube, its rear portion is a round platform cylinder, the front portion is a cylinder, constitute a spout chamber between the rear portion of core bar and the spout cavity inner chamber, the gas outlet in spout chamber is at the round platform base of the round platform cylinder of core bar and the annular slot place between the spout cavity front end; At the fixedly connected resonant cavity cover of core bar front end, the outlet of resonant cavity is positioned at resonant cavity cover edge, and described resonant cavity cover outer edge has the lead angle of suitable sound wave unofficial biography; Form resonant cavity between the frustum of a cone outer wall of described acoustic waveguide tube rear portion and spout cavity.
The utility model has following advantage and good effect:
1, can produce sound pressure level up to 147dB (2 meters), frequency is up to 2.5KHE, and 3 meters its sound pressure levels of in the place ahead are still up to 147dB (free field);
2, compare with the Hartmann oscillator sonic generator, its sound pressure level is significantly improved, wide frequency range, and operating distance is farther, non-directive; Air consumption is little, working media optional (compressed air or high steam);
3, equipment corrosion can not take place in the outer installation of stove, and clogging phenomenon is convenient for installation and maintenance;
4, whole stove outer package, the unofficial biography noise is little, can not produce secondary pollution and influences people's normal life and work.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Concrete structure of the present utility model can be referring to Fig. 1.This device is made of jointly acoustic waveguide tube 1, core bar 4, spout cavity 5, resonant cavity cover 2 and ring flange 6.The forward part of described acoustic waveguide tube 1 is the flared horn shape, and the rear section is cylindric, is fixedly connected with ring flange 6 in its back-end.Rear end at acoustic waveguide tube 1 is connected with spout cavity 5 by hickey.It is step-like that the cavity of this spout cavity 5 is second order, presses airintake direction and be from large to small cavity body structure, and its outside is a truncated cone-shaped reducing shape.Have a core bar 4 to be fixed on the axial location in acoustic waveguide tube 1 and the spout cavity, the front portion of this core bar is cylindric, and the rear portion is round platform and column structure.The rear portion of core bar 4 is corresponding with spout cavity 5, forms the spout chamber jointly.The outlet in described spout chamber is at the round platform base of core bar 4 and the place, slit of the long and narrow ring-type between the front end of spout chamber.The front end of described core bar 4 is fixedly connected with resonant cavity cover 2, and resonant cavity is positioned at resonant cavity cover 2, and its outlet is positioned at the annular slot place of resonant cavity cover lower edge and spout cavity front end.The lead angle structure that one adaptation sound wave unofficial biography are arranged in the outside, lower edge of resonance cover 2.Between the rear portion of acoustic waveguide tube 1 and the spout cavity outside, form a resonator 3.
Claims (1)
