System Instruction:

Metal heat treatment is one of the important processes in machinery manufacturing. There are many types of heat treatment furnaces, and most of them will produce oil fume, waste gas, and dust. According to environmental protection requirements, these must be purified and discharged after reaching the standard. The plant green heat treatment oil fume purification system has been polished for many years, the process is rigorous, the collection effect is good, the equipment runs reliably, and has a unique fire arrest system, which can effectively isolate sparks.

At present, the purification effect, safety, stability and durability of the system have been verified by dozens of Fortune 500 enterprises, foreign-funded enterprises, state-owned enterprises, listed companies and well-known enterprises in the industry. The website space is limited, and we only show a small number of cases, videos and pictures. For more cases, please inquire and make an appointment for inspection.

Application：

Our equipment can be used for forging, annealing, tempering, quenching, heat treatment and other processes. Such heat treatment equipment, as well as the exhaust gas, oil fume pollutants and irritating odors produced by its oil tank and pool.

Smoke Source Analysis：

Heat treatment waste gas source

(1) Oil for quenching and tempering: oil vapor, hydrocarbons and other harmful gases in soot.

(2) Wash and turn blue: sodium hydroxide, sulfur dioxide, trichloroethylene, hydrochloric acid, acetone, benzene.

Among these pollutants, salt bath furnace exhaust gas and quenching oil fume are the main pollutants in heat treatment production in my country.

Fume collection scheme:

According to our experience, the common types of furnaces that need to be designed and collected in heat treatment fume purification projects are: table furnace, pit furnace, mesh belt furnace, quenching oil pool, a total of four working conditions. The collection method and collection point of each heat treatment equipment are different. Common collection methods are as follows. Welcome to inquire directly to get a one-to-one collection plan.

Top suction:

It is located near the fume source, and relies on the suction effect of the hood to inhale harmful substances into the hood, which has little impact on production operations and is easy to install and maintain. It is mainly used in the occasions where the pollution source cannot be sealed due to limited process or operating conditions. The top suction cover is set as an external cover above the harmful material source.

Side Suction：

It is located near the fume source, and relies on the suction effect of the hood to inhale harmful substances into the hood, which has little impact on production operations and is easy to install and maintain. Mainly used in occasions where the pollution source cannot be sealed due to limited process or operating conditions

Side hoods are external hoods that are positioned on the sides of the source of harmful substances

Confined collection:

The pollution sources are all in the confined space, the effect of controlling harmful substances is good, and it is not affected by the ambient air flow, but affects the operation. It is mainly used in the occasions where the harmful substances are more harmful and the control requirements are high.

Smoke Cleaning system:

After the exhaust gas is collected, it enters the pretreatment equipment, and then the exhaust gas enters the pure high-voltage electrostatic oil fume purification equipment and the high and low voltage electrostatic oil fume purifier.

The whole system fully considers the safety performance requirements of the actual operating environment of the equipment such as combustion and explosion in terms of material, process and structural design; the purification efficiency meets the national environmental protection emission limit requirements.

Fire protection system:

In view of the on-site conditions of the heat treatment process, the design of the fire protection system is one of the key points of the entire system. Our fire protection systems have the following features:

(1) The system is designed according to the safety assessment requirements. The equipment is equipped with a temperature control system. When the detected temperature reaches the set value, the system is powered off, the air inlet fire valve is closed, the automatic fire extinguishing system is turned on, and the fan stops running. All systems start automatically when the temperature drops to the set value.

(2) The equipment is equipped with an explosion venting device. When the equipment reaches the explosion limit, the venting disc is opened to relieve pressure.

(3) All connection points shall be connected with anti-static, and the equipment shall be grounded.

The fan adopts explosion-proof fan, and the motor and throat are explosion-proof.

Our advantage

Hundreds of heat treatment oil fume purification engineering cases, the technology is mature and reliable.

Familiar with various complex working conditions in the heat treatment workshop, and can issue one-to-one solutions with ease.

The purification effect exceeds the environmental protection requirements, and there is a real third-party test report as proof.

The system has high stability and security, and can stand the test of strict standards.
