The emergence of catalytic combustion equipment in foundries has solved the problem of exhaust gas treatment in the casting industry and has been recognized and praised by customers The catalytic combustion equipment in the foundry is a new type of catalytic combustion treatment and purification equipment for organic waste gas. It uses activated carbon material technology and is easy to replace and maintain. It is a recent technology for treating organic waste gas
Foundry catalytic combustion equipmentThe product has high market sales and high usage rate. Hebei Zhonghe Environmental Protection
Foundry catalytic combustion equipmentTo introduce the composition and processing of:
Composition of Catalytic Combustion Equipment in Foundry1. Main exhaust fan
The main component of the circulatory system, which guides the exhaust gas to operate in a set channel.
2. Desorption fan
Another major component of the circulatory system is responsible for introducing the hot gas flow into the adsorption bed to desorb organic matter, while also introducing the organic matter into the catalytic combustion device for decomposition.
3. Pneumatic and electric valves
According to the operating conditions, it is necessary to control the detachment temperature of the entire equipment during pipeline switching and detachment under electrical control.
4. Electric control part
The central hub of the entire equipment is controlled by PLC program and HMI human-machine interface, ensuring the normal and automatic operation of each device, while also providing protection, control, and monitoring for each power point.
Main functions of PLC control system:
It has two operation modes: automatic and manual;
It has a chain function during automatic operation;
The system has a self diagnostic function;
Abnormal situations that occur during operation can trigger an alarm and automatically shut down;
The control cabinet panel process can display the main operating parameters;
Change control parameters according to process requirements;
During automatic operation, it can be exited according to the process conditions.
Process of Catalytic Combustion Equipment Treatment in Foundry1. The exhaust gas containing organic matter passes through the activated carbon adsorption layer by the action of the fan, and the organic matter is adsorbed inside by the force of the activated carbon, and the clean gas is discharged; After a period of time, when the activated carbon reaches saturation, adsorption stops, and the organic matter has already been concentrated in the activated carbon.
2. The catalytic purification device is equipped with a heating chamber. When the heating device is activated and enters the internal circulation, when the hot gas source reaches the boiling point of organic matter, the organic matter evaporates from the activated carbon and enters the catalytic chamber for catalytic decomposition into water and carbon dioxide, while releasing energy. When the released energy enters the adsorption bed for desorption, the heating device stops working, and the organic waste gas maintains spontaneous combustion in the catalytic combustion chamber. The exhaust gas circulates until the organic matter is separated from the activated carbon and decomposed in the catalytic chamber. Activated carbon has been regenerated, and organic matter can be decomposed and treated.
The appearance design of the catalytic combustion equipment in the foundry is attractive and easy to use, which can achieve customized products. The same product can also be tailored to different industries in terms of functional design. The front-end dust control and end of pipe waste gas control can be effectively combined in design, providing you with a complete set of waste gas treatment projects.
