Embodiment 1

[0026] The processing method of waste gas in the production of centella asiatica extract comprises the steps:

[0027] 1) Spray tower absorption: the waste gas generated during production is concentrated and then enters the spray tower for treatment;

[0028] The spray tower is two stages connected in series. The two-stage spray tower is equipped with fillers. The liquid phase substance in the spray tower is water. The two-stage spray tower plays a protective role and is connected with the subsequent process treatment;

[0029] 2) The processed gas is transported through pipelines to the chimney in the factory for high-altitude discharge;

[0030] Described filler is prepared by the following method:

[0031] a. Raw material preparation: prepare fiber silk and mango peel according to the weight ratio of 90:10;

[0032] b. Processing of mango peel:

[0033] ① Grinding treatment: After crushing or crushing, add pure water equivalent to 8-10 weight of mango peel, process it wi...

Abstract

The invention discloses a treatment method of waste gas during centella extract production. The treatment method includes following steps: 1), using spraying towers for absorbing: centralizing the waste gas generated during production, and enabling the waste gas to enter the spraying towers for treatment, wherein the spraying towers are in serial connection and at two stages, the spraying towers are filled with a filler, liquid-phase substance in the spraying towers is water, and the second-stage spraying tower plays a role in protection and is connected with a subsequent process for treatment; 2), delivering the treated gas into a chimney in a factory through a pipeline to be discharged into air.

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 centella asiatica extract. Background technique [0002] Centella asiatica is a perennial creeping herb. Alias: Shibaque, Bengdawan, Callagrass, Gotu Kola, Cocklegrass, Coppermoss, Luodeda, etc. Born in damp wastelands, beside villages, roadsides, and ditches. The stem prostrates to the ground and takes root at the nodes. The leaves are alternate, with long petioles; the leaves are round or reniform, 2-4 cm in diameter. Centella asiatica (L.) Urban is the dried or rooted whole plant of Centella asiatica (L.) Urban, a dicotyledon Umbelliferae. Contains a variety of α-amyresin-type triterpenes, including Asiaticoside, Thankuniside, Isothankuniside, Madecas-soside ), Brahmoside, Brah-minoside and Brahmic acid, and Madasiatic acid. [0003] In the prior art, the extraction method of madecassoside generally adopts ...
