Abstract
The invention discloses an efficient noise elimination static pressure tank. The efficient noise elimination static pressure tank comprises a static pressure tank body. A noise elimination cavity is formed in the surface of the inner side of the static pressure tank body. The noise elimination cavity is filled with a noise elimination sponge. Air guide pipes are arranged on the upper portion of the static pressure tank body, and noise elimination tiles are arranged inside the corresponding air guide pipes. Airflow speed brakes are arranged on the lower portion of the static pressure tank body, and porous noise reduction rubber sheets are arranged on the surfaces of the corresponding airflow speed brakes. According to the efficient noise elimination static pressure tank, the noise elimination cavity is formed in the inner side of the static pressure tank body, and the noise elimination cavity is filled with the noise elimination sponge; when gas impacts the static pressure tank body, the noise elimination sponge can absorb part of impacting sounds; under the action of the airflow speed brakes, the airflow speed of the gas is decreased; moreover, when the gas makes contact with the porous noise reduction rubber sheets on the airflow speed brakes, sounds generated by part of the gas can be absorbed by the porous noise reduction rubber sheets; and the noise elimination tiles can absorb part of noise generated by the gas in the static pressure tank body, and thus a good noise elimination effect can be achieved.
Description
Technical field
The invention belongs to noise elimination technique field, and in particular to a kind of efficient noise elimination plenum chamber.
Background technology
Plenum chamber is that supply air system reduces dynamic pressure, increases static pressure, steady air flow and reduces a kind of necessary accessory of airstream vibration, and it can make air-supply effect more preferable.Air can cause noise when through plenum chamber, for the higher equipment of quiet requirement, it is necessary to reduce noise.Current plenum chamber is varied, and the quiet measure taken is also varied, but all preferable not to the utmost, and the noise of reduction is limited.A kind of efficient noise elimination plenum chamber is proposed for this.
The content of the invention
It is an object of the invention to provide a kind of efficient noise elimination plenum chamber, to solve the problems, such as above-mentioned background technology in propose.
For achieving the above object, the present invention provides following technical scheme：A kind of efficient noise elimination plenum chamber, including plenum chamber body, air outlet is provided with the top of the plenum chamber body, the bottom of the plenum chamber body is provided with air inlet, and the inner surface of the plenum chamber body is provided with noise reduction cavity, and the inside of the noise reduction cavity is filled with silencing cotton, the top of the plenum chamber body is provided with guide duct, the inside of the guide duct is provided with Noise reduction tile, and the bottom of the plenum chamber body is provided with flow slowing down plate, and the surface of the flow slowing down plate is provided with the reducing noise rubber plate of porous.
Preferably, the flow slowing down plate is set to 2 groups, and every group of 2-4 block, flow slowing down plate is in 450It is arranged in parallel.
Preferably, the guide duct is placed equidistant in interval.
The technique effect and advantage of the present invention：The efficient noise elimination plenum chamber fills silencing cotton by being provided with noise reduction cavity on the inside of plenum chamber body in the inside of noise reduction cavity, and in air impingement plenum chamber body, silencing cotton can absorb the sound of part shock；In the presence of flow slowing down plate, the speed of air-flow is reduced gas, and gas is being contacted with the porous reducing noise rubber plate on flow slowing down plate, and the sound that a part of gas is produced is absorbed by the reducing noise rubber plate of porous；When last gas passes through guide duct, because the inside of guide duct is provided with Noise reduction tile, Noise reduction tile can absorb the partial noise that gas is produced in plenum chamber body, by the common noise reduction of three kinds of structures, good erasure effect can be reached, the incomplete problem of current plenum chamber noise reduction is solved.
