| Zeolite Wheel Integrated Machine Adsorption concentration is a new generation of VOCs treatment equipment, which combines adsorption concentration unit and thermal oxidation unit organically. It mainly targets high air volume and low concentration organic waste gas. After adsorption purification and desorption, it is converted into low air volume and high concentration organic waste gas for thermal oxidation treatment, and the heat released by the combustion of organic matter is effectively utilized. |

| High voltage pulse bag filter The pulse bag filter is composed of an ash hopper, an upper box, a middle box, a lower box, and other parts. The upper, middle, and lower boxes are divided into compartments. During operation, dusty gas enters the ash hopper through the air inlet duct. Coarse dust particles directly fall into the bottom of the ash hopper, while fine dust particles enter the middle and lower boxes upwards with the turning of the airflow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe exhaust duct, and is discharged to the atmosphere through the exhaust fan. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room). Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time to ensure that the dust peeled off from the filter bag settles in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The filter bag is thoroughly cleaned, and the exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable controller. |

| Oblique plug-in filter cartridge dust collector After the dusty gas enters the dust collector under the guidance of the fan, due to the sudden expansion of the airflow end face and the effect of the airflow distribution plate, some of the coarse dust particles in the airflow settle into the ash hopper under the action of gravity and inertia force; Dust particles with fine particle size and low density enter the filtration chamber, and through the combined effects of Brownian diffusion and fiber interception, the dust settles on the surface of the filter cartridge. The purified gas enters the clean air chamber and is discharged through the air outlet and fan. The resistance of the filter cartridge dust collector increases with the increase of dust on the surface area of the filter cartridge. When the resistance reaches a certain set value, a high-speed and high-pressure airflow is sprayed through the small hole of the spray pipe through the pulse valve of the blowback system to clean the dust. At this time, the PLC program controls the opening and closing of the pulse valve. When the pulse valve is opened, the compressed air in the air bag expands through the Venturi tube and evenly enters the inside of the filter cartridge, forming an instantaneous positive pressure inside the filter cartridge, generating huge vibrations, causing the dust deposited on the filter material to fall off and fall into the ash hopper. The collected dust is discharged into the ash bin through the ash discharge valve. |

| Honeycomb activated carbon adsorption and concentration equipment Honeycomb activated carbon adsorption treatment of organic waste gas utilizes the characteristic of activated carbon micropores that can absorb organic substances. It adsorbs organic solvents from high air volume and low concentration organic waste gas onto activated carbon and concentrates them. After adsorption purification, some gases meet the standards and are directly discharged. Catalytic combustion desorption is the process of using hot air generated from the decomposition of organic waste gas by catalytic combustion to heat the adsorbed organic solvents in activated carbon, bringing them to the boiling point of the solvent. The concentrated high concentration waste gas is then introduced into the catalytic combustion device for thermal oxidation reaction and discharged after meeting the standard. |

| Side mounted filter cartridge dust collector After the dusty gas enters the dust collector under the guidance of the fan, due to the sudden expansion of the airflow end face and the effect of the airflow distribution plate, some of the coarse dust particles in the airflow settle into the ash hopper under the action of gravity and inertia force; Dust particles with fine particle size and low density enter the filtration chamber, and through the combined effects of Brownian diffusion and fiber interception, the dust settles on the surface of the filter cartridge. The purified gas enters the clean air chamber and is discharged through the air outlet and fan. The resistance of the filter cartridge dust collector increases with the increase of dust on the surface area of the filter cartridge. When the resistance reaches a certain set value, a high-speed and high-pressure airflow is sprayed through the small hole of the spray pipe through the pulse valve of the blowback system to clean the dust. At this time, the PLC program controls the opening and closing of the pulse valve. When the pulse valve is opened, the compressed air in the air bag expands through the Venturi tube and evenly enters the inside of the filter cartridge, forming an instantaneous positive pressure inside the filter cartridge, generating huge vibrations, causing the dust deposited on the filter material to fall off and fall into the ash hopper. The collected dust is discharged into the ash bin through the ash discharge valve. |

| Cyclone hybrid spray tower When the production is running, the exhaust fan enters the high-speed mixed flow guide device under traction, and the exhaust gas undergoes gas-liquid emulsification reaction under centrifugal force. Under working conditions, the high-speed rotating mixed flow fluid mixes with the rotating liquid, fully absorbing the miscibility of pollutants and increasing the proportion of smoke and dust. The centrifugal force designed by the cyclone device is used for gas-liquid separation. After separation, the gas enters the adsorption layer of the environmentally friendly packing material, and the corresponding solvent sprayed by the spiral nozzle is evenly distributed on the packing material. Due to the reasonable design of the packing material, pollutants will soak in the packing material for a long time, and the reaction solution will have sufficient solubilization reaction time on the surface of the special environmentally friendly packing material, thus achieving the goal of standard discharge. |

| Integrated filter cartridge dust collector machine After the dusty gas enters the dust collector under the guidance of the fan, due to the sudden expansion of the airflow end face and the effect of the airflow distribution plate, Part of the coarse dust particles in the airflow settle into the ash hopper under the action of gravity and inertia; Fine grained and low-density dust particles enter the filtering chamber, Through the combined effects of Brownian diffusion and fiber interception, dust is deposited on the surface of the filter cartridge. The purified gas enters the clean air chamber and is discharged through the air outlet and fan. The resistance of the filter cartridge dust collector increases with the increase of dust on the surface area of the filter cartridge. When the resistance reaches a certain set value, it passes through the small hole of the spray pipe through the pulse valve of the blowback system, Spray out a high-speed and high-pressure airflow to clean the dust. At this time, the PLC program controls the opening and closing of the pulse valve. When the pulse valve is opened, the compressed air in the air bag expands through the Venturi tube, Uniformly entering the interior of the filter cartridge, a momentary positive pressure is formed inside the filter cartridge, generating huge vibrations that cause the dust deposited on the filter material to fall off and fall into the ash hopper. The collected dust is discharged into the ash bucket through the ash discharge valve. |
