WK-CeraCAT
Ceramic All-in-one Integrated Gas Treatment Technology
for denitration, desulfurization, dust removal, dioxin elimination etc.

The WK-CeraCAT ceramic catalytic filter tube ultra-low emission integrated system for pollutants is a ceramic ceramic integrated industrial kiln flue gas ultra-low purification system that integrates denitrification, desulfurization, defluorination, dust removal, alkali and heavy metal removal through the core element multi tube bundle system. The successful application of this technology not only solves the technical problem of high concentration NOx, high concentration SO2, H2S, HF and other acidic components in industrial kiln flue gas that are difficult to achieve ultra-low emissions, but also overcomes technical bottlenecks such as catalyst poisoning and activity reduction caused by high alkali and heavy metal content in smoke, and effectively solves the conditioning of viscous flue gas conditions, ensuring the long-term stable operation of the integrated system.

Features

Based on the independently developed WK CeraCAT ceramic catalytic filter technology, the company has launched a globally leading ceramic integrated flue gas treatment system, which achieves collaborative treatment of multiple pollutants such as desulfurization, denitrification, defluorination, and dust removal, achieving ultra-low emissions. Combined with artificial intelligence algorithms, it accurately denitrifies and effectively controls ammonia escape. The core component of this technology is the ceramic catalytic filter tube, which is made of ceramic fiber as the basic material and formed through centrifugal fabric technology. The ceramic tube body is deeply impregnated with SCR catalyst using nano impregnation technology, forming a ceramic catalytic filter element with efficient dust removal, desulfurization, and denitrification.

Process Flow

The system consists of an adsorbent powder spraying unit, a reducing agent ammonia spraying unit, a conditioning tower unit, a ceramic catalyst filter tube reaction kettle unit, a waste ash treatment unit, a flue system, a control unit, and auxiliary units. Through the synergistic effect of multiple units, NOx, SO ₂ HF、 Efficient collaborative treatment of multiple pollutants such as dust, and strict control of ammonia escape, with advantages such as simple process, easy maintenance and operation, low operating costs, and long service life. Suitable for high pollutant treatment in industries such as glass kilns, coking, boilers, and waste incineration.

1. Pre treatment stage: flue gas conditioning and pollutant pre removal

• Conditioning tower unit: Through an efficient flue gas dry conditioning device, acidic substances such as SO₂and viscous substances in the flue gas are pre removed, and a specially developed and produced static mixer is used to achieve uniform mixing of flue gas and lime powder, optimizing the flue gas conditioning effect and ensuring efficient removal of acidic pollutants in the flue gas..
• Adsorbent powder spraying unit: Based on the parameters of the user's kiln flue gas, it is recommended to use Ca (OH)₂with a mesh size of not less than 300, purity>90%, and moisture<0.8% as the desulfurizer for dry flue gas desulfurization.. In order to efficiently utilize adsorbents, "Zhongtianweier" not only uses high-precision metering injection of adsorbents, but also adopts the company's independently developed anti clogging device design to ensure smooth powder feeding and non clogging. In the flue gas transportation process, it adopts a unique WK-TZ high-efficiency conditioning tower or WK-JT static mixer design in key parts of the flue gas duct, which not only effectively achieves uniform mixing of gas-solid two-phase flow, but also effectively improves the removal rate of acidic components in flue gas and reduces the amount of adsorbent used, as well as effectively controls the operating cost of adsorbents.
• Static mixing unit: After the flue gas is fully mixed with the adsorbent, it enters the static mixer and is uniformly mixed with the ammonia gas (NH3) accurately injected by thereducing agent ammonia injection unit..

2. Collaborative treatment of pollutants: integrated collaborative desulfurization, denitrification, and dust removal

• Reducing agent ammonia spraying unit: Generally, 20% ammonia water is used as the reducing agent. The ammonia spraying unit mainly consists of an efficient ammonia water atomization device, a spray gun distributor, a flue gas homogenization device, and a self-control unit. It is an important part of fully atomizing ammonia water and mixing it evenly with flue gas, directly affecting the subsequent denitrification reaction effect. The ammonia spray high-efficiency atomization device independently developed and designed by "Zhongtianweier" has unique technical advantages and can achieve maximum flue gas denitrification effect.
• Ceramic catalyst filter tube reaction kettle device(Core link): The design of Zhongtianweier reaction kettle is completely based on the German design concept of ceramic integration, incorporating the differences and flue gas characteristics of domestic glass kilns. From the inlet flue of the reaction kettle to each independent chamber, smooth simulation analysis of flue gas flow is carried out. Not only is the flue guide plate embedded, but also the chamber guide plate design is embedded to ensure that the flue gas enters the reaction kettle with uniform and smooth distribution, ensuring the high efficiency of the ceramic catalyst tube multi bundle and the system, effectively reducing the consumption of consumables, preventing ammonia escape, etc.

3. Waste ash treatment unit

• Backblowing and dust cleaning: Based on the problem of high calcium sulfur ratio in traditional ceramic integrated system calcium hydroxide dry desulfurization, Zhongtianweier uses intelligent algorithms and high-efficiency energy-saving control methods to optimize the blowback parameters, effectively improving the utilization rate of calcium hydroxide powder.
• Dust collection and pneumatic conveying device: Concentrate dust collection at the discharge port of the integrated ceramic desulfurization, denitrification, and dust removal equipment, and transport it to the waste bin to ensure a clean on-site environment and avoid personal injury to on-site operators; During the dust collection control process, based on the high limit alarm signal of each reaction kettle ash hopper, the system starts the unloader and unloads the ash according to the order of the alarm signal. The time for each unloading cycle can be set in the reserved window on the interface.
