Source of pharmaceutical factory exhaust gas generation

There are two main sources of exhaust gas generation in pharmaceutical factories: one is generated during the pharmaceutical production process; Secondly, in the process of pollution control. The exhaust gas generated during the pharmaceutical production process is divided into three situations:chemical synthesis、biological fermentation、Extraction process.Chemical synthesis itself is the synthesis of chemical raw materials, which are volatile. The refining process involves the volatilization of organic solvents and drug dust.

The fermentation process will have the odor of fermentation medium mixed with the odor of microbial metabolism, some of which are very unpleasant.

During the extraction and refining process of fermented products, there will also be the volatilization of organic solvents and drug dust.

The waste gas in the process of pollution control mainly includes the volatilization of organic solvents during the recovery process, the volatilization of dissolved components in wastewater caused by aeration during wastewater treatment, and the waste gas generated by microbial metabolism during biological treatment.

Types and hazards of exhaust gases from pharmaceutical factories

In the pharmaceutical industry, various processes of production involve gases, and there are many types, such as methanol, ethanol, chlorine gas, and organic solvents(such asDMF、 Benzene derivatives, organic amines, ethyl acetate, dichloromethane, acetone, methanol, ethanol, butanoneDichloroethane, acetic acid, chloroformwait）According to the different properties of various target gases, some are flammable and explosive, while others can easily cause poisoning and endanger life safety.

Tip: When a chlorine gas leak occurs Quickly evacuate personnel from the contaminated area to the upwind direction and immediately isolate (alert) them, strictly limiting their entry and exit. Enter the site from the upwind direction and avoid contact with substances such as acetylene, turpentine, ammonia, etc. Cut off the leakage source as much as possible. Reasonable ventilation to accelerate diffusion. Dissolve and neutralize with spray water or dilute alkaline water, or combine with pumping (indoor) or strong ventilation (outdoor).

according to《GB37823-2019 Emission Standards for Air Pollutants from Pharmaceutical IndustryIt is known that,Equipment and pipeline components carrying gaseous and liquid VOCs materials should undergo leak detection and repair work, with specific requirements in accordance with GB37822 regulations. ”

ZechuanThe gas detection alarm of technology can effectively24-hour online real-time monitoring of gas concentration, which can be installed in areas with high toxic and harmful gas emissions such as pharmaceutical workshops and boiler pipe chimneys, and real-time uploading of monitoring data. Its independently developed and produced fixed toxic gas alarmMIC100、MIC500TheMIC600All can be monitored in real-timeVOCs concentration values,And gases commonly detected using electrochemical principles in pharmaceutical factories such as methanol, ethanol, chlorine, etc.

Product Features:

If the waste gas generated during the pharmaceutical production process and the waste gas generated during the pollution control process leaks and causes excessive concentration, it can lead to serious safety accidents.ZechuanTechnology suggests that customers install gas detection alarms in places where flammable, explosive, toxic, and harmful gas leaks may occur.

Installation location specifications:

·Installation heightThe measured gas density is greater than the air density, and the detector should be installed at a distance from the groundPosition between 0.3m-0.6m; If the density of the gas being tested is less than that of air, the detector should be installed 0.5-2m above the detection source.

·Installation horizontal distanceThe combustible gas detector has an indoor detection radius of5m， The outdoor detection radius is 10m, while the toxic gas detector has an indoor detection radius of 2m and an outdoor detection radius of 4m.

ZechuanThe technology has its own mature gas safety monitoring system, which outputs signals and switch values in real time from the gas detection layer to the regional control layer, and then to the upper position layer and interlocking control layer.

Leakage of exhaust gas occurs in the feeding, reaction, solvent recovery, filtration, centrifugation, drying, discharge and other process sections of pharmaceutical factoriesZechuanThe gas safety detection system produced by technology strictly and real-time monitors the gas leakage situation on site, and feeds back the detected data to the staff, ensuring the smooth operation of the project and the personal safety of the staff.
