Heat treated oil fume exhaust gas is a common pollutant in industrial production, with complex components and distinct characteristics. Effective collection methods and solutions are needed to cope with it. The following is a detailed explanation of the composition, characteristics, collection methods, and solutions of heat treated oil fume exhaust gas:

1、 Ingredients

The main components of heat treated oil fume exhaust gas include:

Carbon oxides: such as carbon monoxide, mainly come from processes such as fuel or atmosphere combustion.

Sulfur oxides: such as sulfur dioxide, mainly come from processes such as fuel or atmosphere combustion.

Nitrogen oxides: mainly derived from processes such as fuel or atmosphere combustion, nitrate bath, alkaline blackening, etc.

Hydrogen cyanide and alkali metal hydrogenation: mainly derived from processes such as liquid carburization, gas and liquid carbonitriding.

Other harmful substances, such as ammonia, chlorine, chloride, fluoride, etc., may originate from processes such as ammonia infiltration, silicon infiltration, boron infiltration, acid washing, etc.

In addition, the oil fume exhaust gas also contains harmful substances such as smoke, benzopyrene, benzoanthracene, carbazole, and other polycyclic aromatic hydrocarbons.

2、 Characteristics

The heat treatment of oil fume exhaust gas has the following significant characteristics:

Complex ingredients: containing various harmful substances, posing a threat to the environment and human health.

Oil fume has strong instantaneous characteristics: it has a strong impact force and is difficult to capture and handle.

Low ignition point of oil: often accompanied by flames, increasing the difficulty of treatment.

High oil mist temperature: high oil content, high concentration of exhaust gas, requiring efficient treatment equipment.

3、 Collection method

For the collection of heat treated oil fume exhaust gas, the following methods are mainly adopted:

Oil fume collection hood: set on the furnace cover, arranged in a circular shape along the furnace cover, sucked in by negative pressure, and then sent to the purification machine for purification.

Quenching oil tank oil fume collection: Due to the relatively complex collection of oil fume in the quenching oil tank, different collection methods need to be adopted according to the different oil tanks. For example, reserve space above the quenching oil tank so that the quenched parts can be covered before coming into contact with the oil surface to collect oil fumes to the maximum extent possible.

4、 Solution

In order to effectively treat the oil fume exhaust gas from heat treatment, there will be various solutions. Now, we introduce a set of cooling, dust removal, and purification exhaust gas solutions:

High voltage wet static electricity

Principle: Mainly through the combination of high-voltage electrostatic field and flowing water, particles are separated and precipitated in water. After being charged under the action of a high-voltage electric field, some particulate matter in the flue gas is detached by the force of the electric field, and then suspended on water droplets, and enters the water pool for sedimentation with the flow of water, thereby achieving the effect of purifying the air.

Features: Efficient and energy-saving for oil fume, dust, and cooling, with high purification rate.

Application scope: Waste gas treatment plants, chemical plants, pharmaceutical plants, etc.

Pipeline pre spray system: By spraying the system inside the pipeline, it reduces the accumulation of dust and mist in the airflow, reduces pollution on the inner wall of the pipeline, and lowers temperature.

In summary, the composition of heat treated oil fume exhaust gas is complex and distinctive. Suzhou Baigong Environmental Protection Technology Co., Ltd. (BeeGom) investigates the different working conditions of each customer and adopts targeted and effective collection methods and solutions for treatment. By scientifically and reasonably selecting and using relevant equipment and technologies, effective treatment of heat treated oil fume and waste gas can be achieved, reducing the harm to the environment and human health.
