Zeolite rotor + RCO
YQC zeolite rotor RCO is suitable for treating VOCs with large air volume and low concentration. After passing through the zeolite rotor, due to the van der Waals force between the molecules, the VOCs are adsorbed by the zeolite micropores, and the purified gas can be discharged to the exhaust pipe directly. The organic matter adsorbed on the zeolite rotor is then desorbed by the gas at a temperature of 180℃~200℃. The adsorbed high concentration waste gas is then sent to RCO furnace for catalytic combustion treatment. SEED specializes in manufacturing zeolite rotor RCO.

Greenstar environmental protection zeolite rotor + high temperature oxidation furnace TO direct-fired TO furnace, regenerative thermal oxidation decomposer, also known as direct-fired thermal oxidizer. The basic principle of the main body consists of a combustion chamber and three ceramic filled beds. When the exhaust gas passes through the ceramic beds, it is heated above 800℃ and oxidization reaction occurs, producing carbon dioxide and water. The heat released during decomposition is also recovered to achieve the dual purpose of environmental protection and energy saving. Zeolite rotor + high-temperature oxidizer (TO) process flow: VOCs gas collection → dry/wet filtration → zeolite rotor adsorption and concentration → high-temperature oxidizer TO → fan + chimney (up to the standard discharge)
bag filter
Bag filter is a dry dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, using the filtering effect of fiber fabrics to filter the dusty gas. When the dusty gas enters into the cloth bag dust collector, the particles of large, large dust, due to the effect of gravity will settle down and fall into the dust hopper, and when the gas containing fine dust passes through the filter material, the dust will be blocked, so as to make the gas be purified.
cartridge dust collector
The cartridge dust collector is composed of cartridge as the filter element or adopts pulse blowing dust collector. According to the installation method, the cartridge dust collector can be divided into inclined insertion type, side-mounted type, lifting type and top-mounted type. Cartridge dust collector can be divided into long-fiber polyester cartridge dust collector, composite fiber cartridge dust collector, anti-static cartridge dust collector, flame-retardant cartridge dust collector, coated cartridge dust collector, nano-cartridge dust collector and so on according to the cartridge material.
electrostatic precipitator
The working principle of electrostatic precipitator is to use high voltage electric field to ionize the flue gas, and the dust in the gas stream is charged and separated from the gas stream under the action of electric field. The negative electrode is made of metal wires with different cross-sectional shapes, called discharge electrode. The positive electrode is made of metal plates with different geometrical shapes and is called the dust collection electrode. The performance of electrostatic precipitator is affected by three factors such as the nature of dust, equipment construction and flue gas flow rate. Specific resistance of dust is an index for evaluating electrical conductivity, which has a direct influence on dust removal efficiency. Specific resistance is too low, dust particles are difficult to maintain in the dust electrode, resulting in its return to the gas flow. Specific resistance is too high, the dust particles to reach the dust electrode charge is not easy to discharge, the formation of a voltage gradient between the dust layer will produce local breakdown and discharge phenomenon. All these situations will cause a decrease in dust removal efficiency.

Mist eliminator performance and fog particle diameter with good, in order to achieve good mist elimination effect.
Condensation Recovery System
A condensation recovery system is a device commonly used in the chemical and pharmaceutical industries to recover and separate gases by condensing gases, such as steam, into liquids in a device through cooling and condensation methods. Its main function is to manage gases containing harmful gases or pollutants, and it is widely used in industrial environments such as chemical and pharmaceutical industries. In certain production processes, chemical, pharmaceutical and other industries need to use a large number of substances in the gaseous state, these gaseous substances will be brought out at the same time like pollutants in the production process, if there is no recovery and treatment of these gases, it will cause great harm to the environment and human health. Therefore, the use of condensation recovery system can achieve the purpose of energy saving and environmental protection and reduce the pressure of environmental protection. The principle of the condensation recovery system is based on the heat transfer and phase change of the gas as it flows through the condensing pipes. When the gas flows in the pipeline, it will take away a lot of heat. When the temperature of the pipeline drops below its dew point, the water vapor in the gas will condense into liquid, thus realizing the recovery of the gas. For harmful pollutants such as chemicals, specific solutions are added to the condensation recovery system to eliminate their toxicity through chemical reactions.
