1. Formaldehyde Waste Gas Components

The main components of formaldehyde waste gas include nitrogen (N2), hydrogen (H2), carbon dioxide (CO2), carbon monoxide (CO), water vapor (H2O), and a small amount of flammable gases such as formaldehyde (CH2O), methanol (CH3OH), and methane (CH4). Main gases: nitrogen (N2), hydrogen (H2), carbon dioxide (CO2), carbon monoxide (CO), and water vapor (H2O), these gases account for the majority of the waste gas.

2. Characteristics of Yellow Phosphorus Waste Gas

Yellow phosphorus waste gas contains 80%~90% CO by volume. The previous treatment method for yellow phosphorus waste gas was to light a "sky lantern", which means that after simple water treatment, it was directly burned and discharged into the atmosphere. This not only fails to achieve comprehensive resource utilization but also seriously pollutes the environment.

3. Application Scenarios of Chemical Waste Gas

Formaldehyde waste gas is mainly used in heating equipment such as hot blast stoves and boilers. Zhongwei Company has developed various types of burners to meet the production needs of various application scenarios for the characteristics of low calorific value chemical gas. Mainly used in boilers, dryers, hot blast stoves, incinerators and other heating equipment. Control systems such as damper proportional adjustment, frequency conversion proportional adjustment, touch screen digital control, and PLC frequency conversion proportional control can be configured according to user requirements.

1. Adaptable to various industrial waste gas combustion, such as hydrogen cyanide waste gas, cracking gas, methanol waste gas, dimethyl ether waste gas, biogas, dry gas, synthesis gas, etc.

2. As long as the gas contains combustible components, it can be used as burner fuel. Burners with different structures can be designed and manufactured for different gas compositions and different calorific value gases to meet the needs of various fuels for users.

3. Fire detection method: UV ultraviolet detection, equipped with dual-probe flame detection flameout protection, automatic ignition, valve leak detection, overtemperature and overpressure protection, and status parameter display functions.

4. A safety protection and adjustment system can be configured to realize functions such as program ignition, automatic adjustment, and fault protection.

5. The waste gas valve group is designed with double shutoff, and the flame detection realizes the dual-probe detection function to ensure the stable combustion of the equipment.

6. If the waste gas pressure is low, a backfire prevention device is designed in the pipeline to prevent the waste gas from burning in the pipeline and causing an explosion. A double electric regulating valve is used, and a segment fire type, damper proportional adjustment type, frequency conversion proportional adjustment type, touch screen digital control, and PLC frequency conversion proportional control system can be configured according to user requirements.
