Description

Noise reduction device for reducing oxygen discharge sound of deaerator

Technical Field

The utility model relates to a reduce the technical field of oxygen-eliminating device row oxygen mouth noise, especially a reduce the device of making an uproar that falls of oxygen-eliminating device row oxygen sound.

Background

The principle of the deaerator is that water is sprayed out in a spiral shape through a film-drawing pipe according to a certain angle to exchange heat with heating steam to deaerate, and the supplied water is heated to a saturation temperature corresponding to the working pressure of the deaerator, so that oxygen and other gases dissolved in the supplied water can be removed. The deaerator is one of key equipment of a boiler and a heating system, if the deaerator has poor deaerating capacity, serious loss caused by corrosion to a boiler water supply pipeline, an economizer and other accessory equipment is caused, and if water is introduced into the boiler without being treated by the deaerator, the service life of the boiler is undoubtedly reduced.

When the oxygen-eliminating device in the course of the work, can be from the discharge of a large amount of gas of the gas vent department at its top, during the exhaust, still produce great noise, the very big pollution of noise workman's operational environment around, consequently need to fall the noise treatment to the oxygen-eliminating device. The existing treatment mode of some enterprises is to directly connect a silencer at the exhaust port of a deaerator, and the silencer reduces noise after gas passes through the silencer. However, the volume of the silencer is larger than that of the deaerator, which greatly occupies the space in a workshop, and in addition, the silencer is expensive, which increases the use cost. Therefore, a noise reduction device with good noise reduction effect, low manufacturing cost and no space occupation is needed.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 1 to 4, a noise reduction device for reducing oxygen discharge sound of an oxygen remover comprises a conical tube 3 fixedly arranged at an exhaust port 2 of the oxygen remover 1, a partition plate 4 is welded in the conical tube 3, a plurality of step holes 5 are formed in the partition plate 4, the step holes 5 are uniformly distributed on the partition plate 4, a cylinder 6 communicated with the conical tube 3 is fixedly arranged at the top end of the conical tube 3, the upper end of the cylinder 6 extends upwards to the outside of the conical tube 3, the bottom end of the cylinder 6 abuts against the top surface of the partition plate 4, an acoustic absorbent cotton layer 7 is filled in the cylinder 6, the top of the cylinder 6 is sealed, a hollow tube 8 is welded at the sealed end of the cylinder 6, the top of the hollow tube 8 is sealed, the lower end of the hollow tube 8 is communicated with an inner cavity of the cylinder 6, a plurality of radial holes 9 are formed in the cylindrical surface of the cylinder 6 in the length direction of the cylinder, each radial hole 9 is communicated with the hollow tube 8, a straight tube 10 is welded at the outside of the cylinder 6, a bent tube 11 communicated with the side wall of the straight tube 10 is connected with the straight tube, and the straight tube 11 is perpendicular to the straight tube 10.

The internal thread has been seted up to the top port department of conical duct 3, the outer wall of barrel 6 is provided with external screw thread 12, and barrel 6 is fixed in conical duct 3 through external screw thread 12 and internal thread threaded connection, consequently damages the back when barrel 6, can dismantle it from conical duct 3, has made things convenient for its maintenance, perhaps packs the cotton layer 7 of inhaling sound to it. The lower port of the conical pipe 3 is connected to the top port of the exhaust port 2 through a pipe clamp 13.

The working process of the utility model is as follows:

s1, the deaerator produces gas at the in-process of deoxidization oxygen extraction, and gas produces the noise when 2 discharges from gas vent, and the workman connects the lower port of conical duct 3 in gas vent 2 department through pipe strap 13 this moment. After the gas enters the tapered tube 3 from the gas outlet 2, the tapered tube 3 buffers the gas because the cavity of the tapered tube 3 is larger than that of the gas outlet 2, thereby realizing the first-stage noise reduction of the gas;

s2, then, the gas flows into the cylinder 6 from each stepped hole 5, in the process, the gas is disturbed to generate vortices, the gas pressure is reduced, and therefore second-stage noise reduction of the gas is achieved; when the airflow passes through the sound absorption cotton layer 7, the sound absorption cotton layer 7 absorbs noise, so that third-level noise reduction of the airflow is realized; the gas passing through the sound absorption cotton layer 7 firstly enters the hollow pipe 8 and then is sprayed out of the radial holes 9 into the straight pipe 10, and in the process, the flowing direction of the gas is changed, the gas pressure is reduced, and therefore fourth-stage noise reduction of the gas is achieved; finally, the gas is discharged to the atmosphere from the straight pipe 10 and the bent pipe 11 in sequence, and in the process, the direction of the gas is changed again, so that the gas pressure is further reduced, and the fifth noise reduction of the gas is realized.

Therefore, the noise reduction device can reduce noise of gas for five times, can greatly reduce exhaust noise of the deaerator, further greatly reduce noise of the deaerator, avoid noise pollution to surrounding working environment, greatly improve working environment of workers and have the technical characteristics of good noise reduction effect. In addition, this device of making an uproar falls in comparison with traditional muffler, and the volume is obviously littleer than the muffler to saved the space, the cost of manufacture is lower than the muffler moreover, thereby greatly saved the cost.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
