Plasma exhaust gas treatment equipment

What is plasma

After solid, liquid, and gas, the fourth state of matter has been discovered by scientists, which is the plasma state described in this article! Physics research has shown that when the external voltage reaches the discharge voltage of a gas, the molecular structure of the gas is disrupted, resulting in the formation of a 'quadruple mixture' consisting of electrons, ions, atoms, and free radicals that surround each other.

Although the electron temperature of gas molecules is high during discharge, the temperature of heavy particles is low, and the entire system exhibits a low-temperature state, hence it is also known as low-temperature plasma.

【2、 Working principle of plasma exhaust gas treatment equipment】

The plasma exhaust gas treatment technology is mainly divided into four research directions, namely dielectric barrier discharge (dual dielectric, single dielectric), discharge (metal, fiber), plate discharge, and microwave discharge. In practical applications, a combination mode is often used.

Under the action of an external electric field, a large number of energy carrying electrons generated by dielectric discharge bombard pollutant molecules, causing them to ionize, dissociate, and excite. This then triggers a series of complex physical and chemical reactions, transforming complex large molecule pollutants into simple small molecule safe substances, or transforming toxic and harmful substances into non-toxic, harmless, or low toxicity substances, thereby enabling pollutants to be degraded and removed.

The average energy generated after plasma ionization is 10 eV, and appropriate control of reaction conditions can accelerate the reaction rate. As a technology in the field of exhaust gas treatment, plasma technology has received high attention from the academic community both domestically and internationally.

【3、 Deodorization process and characteristics of plasma organic waste gas treatment equipment】

Describe the process in detail

Deodorization process

(1) Pre filtration: effective filtration through an air filter to improve the cleanliness of exhaust gas and the effectiveness of ion oxygen purification of exhaust gas.

(2) Oxidation deodorization: used to further remove comprehensive odors and unpleasant odors.

（3）The pre filtered exhaust gas is introduced into the high concentration ion oxygen generation area and mixed with ion oxygen groups. The ion oxygen groups degrade odorous pollutants into carbon dioxide, water, and other small molecules. The purified air is discharged into the atmosphere through ventilation ducts.

Deodorizing characteristics

(1) High processing efficiency

The ion oxygen deodorization device can effectively remove specific pollutants such as hydrogen sulfide (H2S), ammonia (NH3), methyl mercaptan, as well as various odors, with an effect of over 90%.

(2) Safe and reliable, low energy consumption

Adopting high-tech ion oxygen generation and controller, with low wind resistance, long lifespan, and minimal power consumption

(3) Principles of Pure Physical Method

The oxidation reaction is carried out at room temperature and pressure without secondary pollution.

(4) Equipment operates fully automatically

No need for dedicated management, convenient management, extremely low operating costs, and suitable for intermittent operation. There are two control modes: manual and automatic.

(5) Small size and light weight

Small footprint, suitable for renovation projects with compact layout, narrow space and other special conditions.

(6) Complete set of equipment, easy to install
