High concentration industrial VOCs waste gas

1Catalytic combustion equipmentbrief introduction

Catalytic combustion device refers to a device or equipment that burns under the action of a catalyst. The working principle of a catalytic combustion device is to use a catalyst to carry out flameless combustion of organic waste gas at a lower ignition temperature, decomposing the organic waste gas into non-toxic carbon dioxide and water vapor. The catalytic burner electrical control system consists of PLC controller, text display, frequency converter, igniter, ultraviolet sensor, thermocouple and other electronic control equipment, as well as a fan. In addition, the ratio of gas to air is regulated by a zero pressure valve. The entry also provides examples of HC series organic gas catalytic combustion devices and LF-VC direct catalytic decomposition oxidation devices, as well as the unsafe factors and management measures in the use of catalytic combustion devices.

2、 Principle of Catalytic Combustion Equipment System

Natural gas fuel has the advantages of high calorific value and low atmospheric pollution emissions. In general, the combustion of natural gas still emits a certain amount of NO. Due to the impact of NO on environmental pollution, it is necessary to reduce the emissions of N0 during the combustion process of natural gas. Research in the past decade has shown that catalytic combustion technology is fully capable of solving the above problems, enabling gas combustion to meet low emission standards, approaching zero emissions, and effectively improving the thermal efficiency inside the furnace.

The working principle of the burner is to change the energy of the entire system by adjusting the amount of mixed gas entering the combustion system when it is necessary to change the combustion power. At present, the workflow of domestically produced catalytic combustion devices is as follows:

1Exhaust gas pre-treatment equipment2. Gas to gas heat exchanger 3. Preheating chamber 4. Catalytic reactor 5. Gas to gas heat exchanger 6. Purified gas venting.
