Method for reducing noise of air cleaning device of outdoor photochemical comprehensive experiment system

Abstract

The invention discloses a method for reducing noise of an air cleaning device of an outdoor photochemical comprehensive experiment system. The method for reducing the noise of the air cleaning device for the outdoor photochemical comprehensive experiment system comprises the steps: a pipeline used for conveying clean air is arranged so that the diameter of the pipeline is gradually enlarged; a plurality of noise reduction rings arranged in parallel are arranged in the pipeline after the diameter is enlarged; a stainless steel support used for supporting a fan of a condensing device is arranged in a clean air inlet and stainless steel thermometer screens are respectively arranged at the periphery of the stainless support; a quartz glass fiber roller is further arranged in the stainless steel support; and a smog chamber body of a smog chamber faces the outside portion of the position of the clean air inlet and a piece of transparent glass is arranged, tightly attached to the outer side of the smog chamber body and fixed on a frame of the smog chamber. The method for reducing the noise of the air cleaning device for the outdoor photochemical comprehensive experiment system provides a plurality of structures for comprehensive noise reduction and noise reducing effect is good.

Description

technical field [0001] The invention relates to a noise reduction method for a clean air device of an outdoor photochemical comprehensive experiment system. Background technique [0002] Photochemical smog is also called "photochemical pollution". Hazardous mixed smog formed by photochemical reactions in the atmosphere. Such as the chemical pollutants produced by the chemical reaction of hydrocarbons and nitrogen oxides in the atmosphere under the action of sunlight. In 1944, photochemical smog occurred for the first time in Los Angeles, USA. Since then, Tokyo, Mexico City, Lanzhou, Shanghai and many other cities with heavy car pollution have appeared, and it has become a major air pollution phenomenon in many large cities. [0003] Photochemical smog is produced in a complex system, and meteorological conditions (atmospheric stability, wind direction, wind speed, humidity, sunlight flux, etc.), pollutant status (composition, content, emission) and chemical reactions all p...

AI Technical Summary

Problems solved by technology

[0006] Existing systems that can be used for outdoor photochemical comprehensive experiments are usually used for academic research, and the practicability and repeatability are not high. In particular, there is a lack of introduction of corresponding installation and commissioning materials. And the introduction of some situations of experimental research using the smoke box, but the lack of a complete introduction of the structure, installation and debugging of the outdoor photochemical comprehensive experimental system, it is difficult for those skilled in the art to refer to and implement

That is to say, those skilled in the art can't reproduce the existing outdoor photochemical comprehensive experiment system without repeated creative work according to the existing data.
