VOCs governance in pharmaceutical and chemical industries

The production process of chemical drugs consists of two parts: the production of active pharmaceutical ingredients and the production of pharmaceutical preparations. Active pharmaceutical ingredients are the material foundation of drug production, but they must be processed into drug formulations suitable for consumption in order to become drugs. In China, the pharmaceutical industry also includes the production of traditional Chinese medicine. The pharmaceutical industry is not only a sector of the national economy, but also a social welfare undertaking for disease treatment, prevention, healthcare, and family planning.

Deodourisation of community waste rooms

A community refuse chamber is a small refuse collection site located in a neighbourhood, community or flat. Community refuse rooms are usually set up near residential areas for the convenience of residents to dispose of their daily life refuse. The main purpose of a community refuse storage room is to temporarily store refuse to prevent it from being dispersed in the residential area, and to facilitate the residents to sort and put out their refuse. Community refuse storage rooms are usually equipped with waste separation bins for recyclables, food waste, hazardous waste, etc. to facilitate waste separation. Community refuse storage rooms do not reprocess refuse, but only store it temporarily, after which it will be collected and transported by sanitation workers on a regular basis.

Deodourisation of refuse collection points

A refuse collection point is defined as a place used to collect domestic waste generated in the life of a flat or household. The location and extent of the refuse transfer station is an important financial management issue for waste removal. In this way, the waste that is transferred out has changed its character and quantity and has become a residue that is recycled.

Deodorisation of refuse compression stations

Refuse compression station is the town or township residents of the production of domestic waste is concentrated into a compression tank for compression and reduction, and then through the large rubbish trucks will be compressed domestic waste transported to the rubbish disposal site, in short, is the production of domestic waste between the source of rubbish disposal site set up between a transfer point.

Deodorisation of large refuse transfer stations

A refuse transfer station is a refuse transfer station between the place of origin (or concentration) of the refuse and the treatment plant in order to reduce the transport costs of the refuse removal process. Here, the waste from the collection points is consolidated and transferred to larger or other less expensive vehicles for onward transport to the treatment site. The transfer station has a capacity of up to 3,000 tonnes per day. The location and size of the transfer station is an important economic management issue in waste removal. Sometimes a transfer station is built in conjunction with a recycling site. In this case, the waste transferred out has changed its original character and quantity and becomes a residue after recycling.

Deodourisation of waste incineration plants

A common way of treating waste in waste incineration plants is waste incineration, a waste treatment process that involves the combustion of substances contained in the waste. Industrial plants used for waste incineration are often referred to as waste-to-energy facilities. Waste incineration and other high-temperature waste treatment systems are described as thermal treatments. Waste incinerators convert waste into ash, smoke and heat. Ash is formed primarily from the inorganic components of the waste and may be in the form of solid lumps or particles carried by flue gases. Gaseous and particulate pollutants in the flue gas must be removed before they are released into the atmosphere. In some cases, the heat generated by incineration can be used to generate electricity.

Deodorisation of waste treatment centres

A waste disposal centre is a specific place where waste generated from industry, domestic production, health care and so on is centralised for recycling and disposal in order to reduce environmental pollution. There are commonly used methods of waste disposal: sanitary landfill, composting and direct incineration.

Deodourisation of refuse transfer stations

The emergence of refuse transfer stations is the civilised city is more beautiful, no longer have a mountain of rubbish team, no longer have a stinking smell. Refuse transfer station for reasonable classification and processing, the waste that can be recycled and reuse, which reduces the waste, but also waste into treasure.

VOCs organic waste gas is decomposed into carbon dioxide, water, etc. Other waste gas molecules that have not been completely degraded can be oxidized into water-soluble small molecules and some active free radicals.

Zeolite wheel+CO

The zeolite rotary device+catalytic combustion of CO is mainly suitable for treating high concentration CO waste gas. Usually, when the CO concentration is 500 ppm (volume fraction) or higher, a zeolite rotary device combined with catalytic combustion of CO is required for treatment. If the CO concentration is low, other waste gas treatment technologies may be more suitable. Zeolite rotary device is a technology used to separate components from gas mixtures. This type of device usually includes many zeolite molecular sieve wheels, which can selectively adsorb certain molecules without adsorbing other molecules, thereby achieving component separation in gas mixtures. Catalytic combustion of CO is a technology that converts CO (a toxic and harmful gas) into CO2 (a relatively harmless gas). This technology uses catalysts to accelerate the reaction between CO and oxygen, thereby reducing the concentration of CO.

Zeolite wheel+TO

Zeolite wheel+TO direct combustion furnace is an efficient and environmentally friendly industrial waste gas treatment equipment. It can effectively treat various organic pollutants in industrial waste gas through two methods: physical adsorption and high-temperature incineration. This device has the advantages of high efficiency, energy conservation, wide applicability, and easy maintenance, and has broad application prospects in the field of industrial waste gas treatment in the future.

Zeolite wheel+RCO

The zeolite wheel+RCO catalytic combustion equipment is currently a mature and practical process in the field of organic waste gas treatment in China. Adopting a three step continuous program of adsorption desorption cooling, with simultaneous adsorption and desorption. The zeolite wheel first adsorbs and collects organic waste gas, compresses it, and increases its concentration. Then, high concentration waste gas molecules are desorbed from the zeolite wheel and sent to a catalytic oxidation furnace (CO furnace) for flameless combustion. To achieve the purpose of purifying organic waste gas. The zeolite wheel+RCO equipment mainly consists of exhaust gas pretreatment system, zeolite wheel adsorption concentration system, desorption system, catalytic combustion system, cooling and drying system, and automatic control system.

Zeolite wheel+RTO

The zeolite wheel+RTO process is currently one of the hottest processes in the waste gas treatment industry. Compared to other new materials, industries such as new energy, chemical, and semiconductor directly use RTO for incineration. The zeolite wheel RTO process has very guaranteed compliance and safety performance. The working principle of zeolite rotary RTO is to use combustion reactions at high temperatures to oxidize organic compounds in exhaust gas into harmless carbon dioxide and water, thereby achieving the goal of purifying exhaust gas. Its core is a rotating heat exchanger filled with adsorption materials such as zeolite.

Spray tower

Spray tower, as a type of environmental waste gas treatment equipment, exists. According to its working principle, it can be divided into circulating water spray tower, alkali spray tower, and acid spray tower (also known as acid washing tower). According to the material of the tower, it is divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. Choose a reasonable spray material and spray process based on the different properties of the exhaust gas. Spray tower is an important industrial waste gas treatment equipment, whose working principle is to use water and power technology to spray liquid or gas in a mist form into the waste gas, in order to remove harmful substances in the waste gas.
