Embodiment Construction

[0014] of the present invention figure 2 Take the 3 blower noise collection system devices in the example as an example.

[0015] The blower of the sewage treatment plant takes the BK6008 Roots blower as an example, and its technical parameters are: Q=15.2 m 3 / min, P=0.06MPa N=22kw. The noise of a single blower (~115dB), 3 blowers run at the same time, all the blower noise is collected in the sound guide tube through the sound collection section, the length of the sound guide tube is 10~20m, and the contact pool area is 12m 2 , the number of sound pipes is 12 (1 / m 2 ). Through the collection of the system device, the ambient noise in the blower room is 105dB. The noise collecting device is used in the sterilizing treatment of the effluent in the contact pool, and the sterilizing rate of the noise alone is >70%. According to the simultaneous application of the patent "a method of using the noise of the blower in the sewage plant to cooperate with the drug to sterilize th...

Abstract

The invention discloses a noise collecting system device for a sewage plant blower. The noise collecting system device is composed of three parts, namely a sound collecting zone, a sound guiding zone and a sound dividing zone, wherein the sound collecting zone comprises a reflecting shield, a sound collecting shield, a shrinking section, a sound binding section which is used during noise binding of a plurality of blowers, and the like; the sound guiding zone is composed of a straight line sound guiding pipe and an elbow; the sound dividing zone comprises a sound dividing shield, a sound dividing pipe, a sound dividing hole and the like; moreover, a noise reduction layer is arranged outside the whole collecting system. The noise collecting system device can fully collect and guide the blower noise, can reduce noise energy loss as much as possible, can facilitate full utilization of high energy of noise, and has a wide development space and market prospect.

Description

technical field [0001] The invention relates to a sewage plant blower noise collection system device, which belongs to the technical field of new energy and energy saving technologies. Background technique [0002] Noise is the sound made by the sounding body when it is irregular. The sound is caused by the vibration of the object and propagates in a certain medium (such as solid, liquid, gas) in the form of waves. The noise pollution generally referred to refers to man-made. From a physiological point of view, all sounds that interfere with people's rest, study and work, that is, unwanted sounds, are collectively referred to as noise. Industrial Noise Noise generated by various equipment in factories. The sound level of industrial noise is generally high, which has a greater impact on workers and surrounding residents. [0003] The blower room is the main production workshop of the sewage blowing and aeration process in urban sewage treatment plants and garbage treatment ...
