Plasma Deodorization Module

In industrial production, municipal sanitation, sewage treatment, waste disposal and other fields, the emission of industrial waste gas and odorous gases has become an increasingly prominent environmental and compliance issue. Pollutants including volatile organic compounds (VOCs), hydrogen sulfide, ammonia and malodorous gases not only damage the surrounding atmospheric environment, but also cause serious harm to human respiratory and nervous systems, and even restrict enterprises' compliant production. VOCs treatment and odor control have become a core part of global and China's environmental governance.

Our Plasma Deodorizer is a high-efficiency, energy-saving and eco-friendly waste gas treatment equipment. Relying on its unique low-temperature plasma reaction technology, it achieves high-efficiency purification of various odorous and harmful waste gases, helps enterprises realize standard discharge, complies with the energy saving & environmental protection development concept, and is widely used in various odor control scenarios, becoming one of the mainstream equipment in the current waste gas deodorization field.

Industry Odor Treatment Pain Points & Compliance Requirements

Odor and waste gas treatment faces multiple pain points in various industries, and traditional technologies have obvious limitations:

· Adsorption and absorption methods require frequent replacement of adsorbents and absorbents, resulting in high operating costs, solid/liquid waste secondary pollution, and reduced purification efficiency after adsorption saturation;

· High-temperature incineration equipment has huge energy consumption, high investment cost, and potential fire and explosion risks when treating flammable and explosive waste gases;

· Chemical washing methods require continuous addition of chemical agents, with high operating costs and secondary pollution risks.

In China, mandatory standards including GB 14554-93 Emission Standard for Odor Pollutants and GB 16297-1996 Integrated Emission Standard of Air Pollutants set strict limits on the emission concentration of malodorous gases, VOCs and related pollutants. Non-compliant emission will bring huge legal and operational risks to enterprises and municipal facilities, creating an urgent demand for a stable, efficient, low-cost and eco-friendly odor treatment solution.

Core Working Principle

The Plasma Deodorization Module (full name: Low-Temperature Plasma Deodorization and Purification Equipment) adopts advanced low-temperature plasma technology as its core working principle.

Through high-voltage discharge, the equipment generates a large number of high-energy electrons, ions, free radicals and other active particles. These active particles undergo a series of complex physical and chemical reactions with odor molecules and harmful pollutants in the waste gas, cracking and oxidizing pollutant molecules, and finally converting them into harmless carbon dioxide, water and other inorganic compounds, thus achieving the dual goals of deodorization and purification.

Compared with traditional deodorization equipment, the Plasma Deodorizer requires no high-temperature heating and no chemical agents added. The whole treatment process relies on physical and chemical reactions, avoiding secondary pollution. Meanwhile, it has the advantages of high purification efficiency, wide application range and low operating cost, perfectly adapting to the treatment needs of waste gas with different concentrations and components.

Core Structure & Synergistic Functional Units

The Plasma Deodorization Module consists of five core synergistic units, ensuring stable and efficient long-term operation:

Pretreatment System

The pretreatment system is the foundation for stable operation of the whole equipment. It is mainly used to remove particulate matter, oil mist, moisture and other impurities in the waste gas, preventing impurities from entering the plasma reaction chamber and causing electrode blockage, corrosion or reduced purification effect. It is usually equipped with high-efficiency filters and demisters to achieve efficient interception and filtration of impurities.

Plasma Reaction Chamber

The plasma reaction chamber is the core working area of the equipment. It is equipped with high-voltage electrodes and grounding electrodes inside. Through the high-voltage electricity provided by the power supply system, a low-temperature plasma field is formed between the electrodes. When the waste gas passes through the reaction chamber, it fully contacts with the active particles in the plasma field, completing the cracking and oxidation of pollutants.

High-Frequency High-Voltage Power Supply System

The power supply system adopts a high-frequency high-voltage power supply, which has the characteristics of strong stability, low energy consumption and long service life. It can automatically adjust the output power according to the waste gas concentration, ensuring the purification effect while reducing energy consumption. It is equipped with multiple protection mechanisms such as overload protection, short circuit protection and over-temperature protection.

Intelligent Control System

The control system adopts an intelligent design, which can real-time monitor the operating parameters of the equipment, realize automatic start and stop, fault alarm, parameter adjustment and other functions. It is easy to operate, does not require 24-hour on-site supervision by special personnel, and greatly saves labor costs.

Exhaust System

The exhaust system is responsible for discharging the purified clean gas that meets the emission standards, with a reasonable design to ensure stable air flow and no back pressure, supporting the continuous and stable operation of the whole treatment system. 

Core Advantages

Ultra-High Purification Efficiency & Stable Compliance

High-efficiency purification is the core advantage of the Plasma Deodorizer, with purification efficiency far exceeding traditional deodorization equipment.

· It can efficiently treat various odorous and harmful waste gases, including VOCs, hydrogen sulfide, ammonia, methyl mercaptan, benzene series, ketones, esters, etc.;

· For low-concentration and high-air-volume waste gas, the purification efficiency can reach more than 95%, which can quickly remove odors and ensure that the waste gas emission meets national and local environmental protection emission standards;

· Unlike traditional adsorption technology, it will not have the problem of adsorption saturation and purification efficiency decline, and the purification effect is more stable, especially suitable for long-term continuous operation scenarios.
