AI Technical Summary

Problems solved by technology

Disadvantages: susceptible to weather conditions, odorous substances still exist
Disadvantages: low purification efficiency, should be used in combination with other technologies, poor treatment effect on mercaptans, fatty acids, etc.
Disadvantages: limited by the intensity of aeration, the application of this method is still limited
At present, the waste gas extracted by general plants is simply absorbed by water or directly discharged, which will cause serious pollution.

Embodiment 1

[0023] A method for treating waste gas in the production of peony extract, specifically comprising the following steps:

[0024] 1) Low-temperature cooling: the waste gas generated in the production is concentrated and then sent to a low-temperature condenser for low-temperature cooling. The cooling temperature is 0-4°C to realize the preliminary separation of essential oil in the waste gas, and the essential oil enters the low-temperature storage tank;

[0025] 2) Spray tower absorption: the waste gas from step 1) enters the spray tower for treatment;

[0026] Described spray tower is four stages in series, and the liquid phase material in the four stage spray tower is respectively the lye with lower concentration that has added xanthan gum, the lye with higher concentration that has added xanthan gum, Added lye and water with a higher concentration of xanthan gum; the added amount of xanthan gum is 0.5% mass concentration;

[0027] 3) High-altitude discharge: The processed ...

Embodiment 2

[0029] A method for treating waste gas in the production of peony extract, specifically comprising the following steps:

[0030] 1) Low-temperature cooling: the waste gas generated in the production is concentrated and then sent to a low-temperature condenser for low-temperature cooling. The cooling temperature is 0-4°C to realize the preliminary separation of essential oil in the waste gas, and the essential oil enters the low-temperature storage tank;

[0031] 2) Spray tower absorption: the waste gas from step 1) enters the spray tower for treatment;

[0032] Described spray tower is four stages in series, and the liquid phase material in the four stage spray tower is respectively the lye with lower concentration that has added xanthan gum, the lye with higher concentration that has added xanthan gum, Added lye and water with a higher concentration of xanthan gum; the added amount of xanthan gum is 1.0% mass concentration;

[0033] 3) High-altitude discharge: The processed ...

Abstract

The invention discloses a waste gas treatment method in the production of fragant peony extract. The waste gas treatment method includes the following steps of 1 cooling at low temperature, wherein waste gas generated in the production is concentrated and conveyed into a low-temperature condenser to be cooled at the low temperature, the cooling temperature is 0 DEG C-4 DEG C, and essential oil in the waste gas is separated preliminarily and enters a low-temperature storage tank; 2 absorbing though a spray tower, wherein the waste gas coming out enters the spray tower to be treated, the spray tower comprises four levels connected in series, and liquid phase substances at the four levels of the spray tower are low-concentration alkali liquor added with xanthan gum, high-concentration alkali liquor added with xanthan gum, high-concentration alkali liquor added with xanthan gum and water respectively; 3 high-altitude exhaust, wherein the treated gas is conveyed to a chimney in a factory through a pipeline and exhausted to the high altitude.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a method for treating waste gas in the production of peony extract. Background technique [0002] Exhaust gas treatment, also known as Flue gas purification, mainly refers to the work of treating industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. [0003] Waste gas treatment mainly includes the following methods: [0004] 1) Dilution and diffusion method: principle: exhaust the odorous gas to the atmosphere through the chimney, or dilute it with odorless air to reduce the concentration of odorous substances to reduce the odor.
