Problems solved by technology

However, during the spraying granulation process, there was serious pollution of flue gas. Due to the unpleasant smell of the polluted flue gas, the people within a few kilometers around could not live normally, forcing enterprises to limit or stop production.
Scholars at home and abroad have conducted a lot of research on this kind of polluting gas, but so far there is no ideal solution

Embodiment Construction

[0022] The aerosol flue gas 1 is firstly subjected to Venturi washing 2 by using the fermentation waste liquid 3; the washed flue gas is then subjected to the first-level spray washing 4 by using the water in the first-level spray circulation storage tank 5, and the water lost by the circulation washing Supplemented by the secondary circulation washing storage tank 7; after the primary spray washing, continue to use the water in the secondary circulation washing storage tank 7 to carry out the secondary spray washing 6, and the water lost by the secondary spray washing is taken from the clear water pool 8 Supplement; the aerosol flue gas enters the electrostatic processor for treatment 9 after three-stage washing; a clean gas 10 is formed; finally, the organic solution captured by the electrostatic treatment 9 and the washing waste that uses the fermentation waste liquid 3 to pass through the Venturi washing 2 The liquid is returned to the concentrated production process 11 for...

Abstract

The treatment paths for the fermentation waste liquor and dregs in the prior pharmaceutical industry comprise concentration and spraying granulation for the fermentation waste liquor and dregs to form organic and inorganic fertilizers, realize the resource utilization of wastes, govern the pollution, and bring great profits for enterprises. But serious smoke pollution is generated in the process of spraying granulation, and becomes one of main factors for restricting the healthy development of the enterprises. The process carries out independent research and development, determines the property of pollution smoke which is aerosol granular pollutant of VOCs wrapped water molecules, analyzes the components of the smoke through the PT-GC-MS analysis technology, and invents a method for governing spraying granulation aerosol smoke pollution. The process flows of the process comprise Venturi washing of aerosol smoke, primary spray tower washing, secondary spray tower washing and treatment of an electrostatic treater; and the organic substance treatment efficiency of the aerosol smoke reaches more than 95 percent. The treatment process has the main characteristics of high treatment efficiency, low energy consumption and simple operation.

Description

technical field [0001] The invention belongs to the technical field of air pollutant treatment, and relates to the treatment technology of fermentation waste liquid and spray granulation flue gas of medicine dregs in the pharmaceutical industry. Background technique [0002] my country's pharmaceutical industry has achieved rapid development in recent years, and some fermented drugs occupy most of the world's share, laying a good foundation for the status of the pharmaceutical industry in my country's national economy. However, the rapid development of the pharmaceutical industry has brought a lot of waste and pollutants, and the most difficult to deal with is the fermentation waste liquid and medicinal residues. Through technical research and technology introduction in recent years, the utilization of fermentation waste liquid and medicinal residues has been realized. The process is: fermentation waste liquid, medicinal residues→concentration→spray granulation→organic and i...
