Problems solved by technology

[0003] In the prior art, certain silencing equipment will be installed on the air outlet of the fan. These silencing equipment include a silencing pipe, and a plurality of silencing holes are arranged on the silencing pipe. Since the air blown by the fan contains more dust particles, these silencing equipment Dust particles will block the sound-absorbing hole, thus affecting the sound-absorbing and noise-reducing effect of the sound-absorbing equipment

Abstract

The invention relates to the field of paper machining, in particular to a noise treatment system for a paper mill. The system comprises a hush pipe, wherein one end of the hush pipe is provided with arotating sleeve used for being rotationally connected to an air outlet pipe of a fan, the rotating sleeve is provided with an air inlet used for communicating with the air outlet pipe of the fan andan air outlet used for communicating with the hush pipe, a dust filtering cavity is formed in the rotating sleeve, the dust filtering cavity, the air inlet and the air outlet communicate, and a filterscreen is arranged in the dust filtering cavity. In addition, the invention further provides a treatment method adopting the treatment system. Through the treatment system and the treatment method, the noise reduction effect of the paper mill is improved.

Description

technical field [0001] The invention relates to the field of paper processing, in particular to a noise processing method and system for paper mills. Background technique [0002] During the processing of toilet paper, a lot of equipment and devices are required to complete. For example, in paper processing and production, it is necessary to use bamboo chip cleaning devices, vibrators, pulp mixers, alkali furnace dust collectors, and various fans. During the operation of these equipment, it is inevitable that noise will occur, such as the collision and friction of the equipment during operation, and the wind blown by the fan contains certain noise, etc. These noises have seriously affected the living environment of factory workers and nearby residents. bring noise pollution to them. Most of these noises in paper mills are emitted by fans such as blowers and ventilators. Therefore, reducing the noise of fans plays a key role in reducing the noise of the entire paper mill. ...
