What is the process of waste gas in the pharmaceutical workshop, and the utilization of waste gas in

At present, there are many treatment methods for pharmaceutical factory waste gas, such as adsorption and desorption treatment, catalytic combustion, condensation, low-temperature plasma, biofilm method, etc., so in the actual production process, which waste gas treatment method can be used to meet the national waste gas emission standards?

1. Special optical quantum technology is now more widely used, is a new and efficient new process developed by the new research and development, mainly for the treatment of all kinds of odorous waste gas treatment technology, special optical quantum technology equipment occupies a small area, low energy consumption, according to the actual situation for series or parallel use, the application of the occasion is also relatively wide, can be high concentration and need deep treatment, can be applied to this technology, the efficiency of special optical quantum technology waste gas treatment can reach 97%, this technology has great potential, It will be more widely used in the environmental protection industry in the future.

Second, low-temperature plasma, composite photocatalytic treatment technology is also widely used in pharmaceutical factories, the principle of this technology is that low-temperature plasma can produce high-energy electrons, can directly decompose harmful gases in the exhaust gas, so that it can be explained into carbon dioxide or water, etc., and then use compound light to catalyze the molecules that cannot be decomposed, so as to achieve the effect of purification.

Both of these treatment technologies are new methods, and there will be great development in the field of waste gas treatment in the future, which will break the traditional treatment methods and meet the national exhaust emission standards.

Summary. The utilization of waste gas in the preparation workshop refers to the process of collecting, treating and utilizing the waste gas (such as organic waste gas, carbon dioxide, etc.) generated in the pharmaceutical process. The utilization of exhaust gas can reduce pollutant emissions, save energy, etc.

The following are some examples of waste gas utilization in preparation workshops:1For the exhaust gas containing organic matter, it can be oxidized by the organic waste gas oxidation treatment equipment.

The oxidized exhaust gas can be further treated with sulfur removal and nitrogen removal to finally meet the emission standard. The treated oxidized exhaust gas can also be used for waste heat and wastewater. 2.

For carbon dioxide exhaust gas, membrane separation, absorption and other technologies can be used for treatment and utilization. For example, in the process of drug synthesis, the reaction pressure can be adjusted to reduce the generation of carbon dioxide, thereby reducing the emission of exhaust gases. 3.

Exhaust gas can also be used as fuel for boilers, heat pumps and other process equipment to achieve the best utilization of energy. In addition, the organic matter in the exhaust gas can also be converted into valuable compounds by biological treatment or chemical synthesis.

Dear, you can refer to the above points.

Can you elaborate on the process of dissipating the exhaust gas and its composition? Specific problems are analyzed on a case-by-case basis.

As we all know, due to the large variety of drug production, the long production process time, the use of many types of raw materials, large quantities, and low utilization rate of raw materials. Therefore, it also leads to a large amount of "three wastes" generated in the production process of the pharmaceutical industry, complex waste composition, and serious pollution hazards, which brings difficulties to the final waste gas treatment.

Several basic elements of the industrial waste gas treatment program for pharmaceutical plants:

The treatment plan is selected according to the composition of the exhaust gas (whether it contains water, solids, oily substances, and the difficulty of treatment), high concentration, low concentration, and emission form.

The following situations are suitable for choosing the isothermal ion incineration waste gas treatment scheme:

High organic content, complex composition, flammable and explosive, difficult to decompose substances, containing particulate matter, oily matter, continuous large dose of industrial waste gas.

High-temperature plasma incineration technology is the concentrated discharge of high-frequency (30kHz) high-voltage (100,000 volts) high-power power supply under specific conditions. In the reactor, the industrial waste gas treatment rises from normal temperature to 3,000 degrees Celsius, and under the dual action of high temperature and high electric potential, the organic pollutants are ionized and completely cracked instantly. After high-temperature plasma incineration, the organic matter in the industrial waste gas is cracked into elemental substances.

Hello, what to do now?

There are many processes in the pharmaceutical factory that produce organic waste gas, which cannot be directly discharged, and will also lead to a foul smell in the production workshop. Wanchuan environmental protection RCO catalytic combustion equipment can be selected to treat the exhaust gas.

UV photolysis purification + activated carbon adsorption can also be used.

Different pharmaceutical methods produce different exhaust gases. For example, in the process of fermentation and pharmaceutical, solvent waste gas and bacterial residue drying waste gas are mainly produced in the extraction and refining, and the proportion of acetone and ethyl acetate in its components is high, 41% respectively. For chemically synthesized pharmaceuticals, isopropanol, acetone, and ethanol account for the highest proportions, accounting for 78% each.

In biopharmaceuticals, the exhaust gas pollution mainly comes from milling and screening, granulation, drying, total mixing, tableting and capsules.

Dust generated during the filling process.

For different exhaust gas sources, as well as different exhaust gas composition, temperature, pressure, and gas volume, different exhaust gas methods or several combinations are required. The treatment of VOCs in the traditional Chinese medicine industry needs to be carried out according to the nature and emission characteristics of pollutants. The conditions for the emission of organic gases emitted by different industries and different processes in the same industry vary greatly.

In most cases, for dust-containing VOCs, a certain amount of pretreatment is required, and the common treatment methods include dry method, wet method, filtration and static electricity 4 categories, and the devices used include cyclone dust collector (dry method), bag filter (filtration), water film dust collector (wet method) and water spray dust removal (wet method), etc.
