Core making machine catalytic combustion equipmentintroduction
Core making machine catalytic combustion equipmentAlso known as activated carbon adsorption concentration+CO catalytic combustion equipment, also known as regenerative activated carbon adsorption concentration; The catalytic combustion equipment uses activated carbon to adsorb and filter exhaust gas, and the filtered clean gas is discharged through a 15 meter chimney at high altitude; The organic waste gas adsorbed in activated carbon is desorbed from the activated carbon adsorption box by the high-temperature gas released from the RCO catalytic combustion furnace. The desorbed waste gas is then subjected to catalytic oxidation treatment by the RCO combustion furnace.
The activated carbon adsorption box of the catalytic combustion equipment in the chip making machine is equipped with a temperature sensing system and a high-temperature protection system to ensure the stable operation of the equipment. The adsorption medium selected is high-value honeycomb activated carbon, which has high adsorption efficiency, low wind resistance coefficient, and excellent adsorption, desorption, and gas dynamic properties.
The upper part of the catalytic combustion furnace of the chip making machine is the exhaust gas catalytic decomposition zone, and the lower part is the alternating heat exchange zone between cold and hot air; The catalytic combustion furnace produced by Hebei Zhonghe Environmental Protection adopts an electric heating system and a finned stainless steel yellowing process heating device,
Uniform heat dissipation and long service life.
Catalytic combustion principle
The principle of catalytic combustion process in chip making machine is to oxidize gaseous pollutants with lower temperature organic waste gas (250-300 ℃) under the action of catalyst, with a removal efficiency of over 99% and a heat recovery efficiency of over 90%. The heat recovery of RCO utilizes the high thermal conductivity of ceramic materials as a heat exchange medium to obtain a relatively complete thermal conductivity.
Combining chemical reactions with heat exchange in a fixed bed reactor greatly improves the utilization of thermal energy, achieves high reaction heat recovery, and achieves energy-saving and emission reduction effects. The products after purifying organic waste gas are harmless CO2 and H2O, which will not cause secondary pollution. When purifying high concentration exhaust gas, some of the reaction heat can be removed from the high-temperature zone in the middle of the reactor, which can produce high-grade thermal energy while purifying the exhaust gas and achieve economic benefits. For simple reversible exothermic reactions, a higher one-way conversion rate can be obtained due to the lower outlet temperature compared to the optimal steady-state operation. For complex reactions, the selectivity of the process can be improved or the yield can be increased. The catalyst in the RCO catalytic combustion equipment adopts precious metal honeycomb ceramic catalyst, which has strong catalytic activity and a removal rate of ≥ 95%.
Control system for catalytic combustion equipment of chip making machine: fully intelligent operation, one click start, no need for excessive manual participation, automatic conversion of adsorption and desorption programs. And monitor the exhaust gas temperature in real time, and make appropriate operating instructions based on different temperatures. Built in protective systems, emergency systems, alarm systems, and other protective procedures ensure the smooth operation of the equipment.
The core making machine catalytic combustion equipment produced by Hebei Zhonghe Environmental Protection Equipment Co., Ltd. has a high technical safety factor, with safety measures for temperature control system, explosion-proof system, and water spray system. Catalytic combustion technology combines the advantages of adsorption and catalytic combustion methods, using a new type of adsorption material (high-quality honeycomb activated carbon) for adsorption. After approaching saturation, hot air is introduced for desorption and desorption. After desorption, the exhaust gas is introduced into the catalytic combustion bed for flameless combustion, purifying it. The hot gas is recycled in the system, greatly reducing energy consumption
