Product Description

Decanters for Coal Tar Recovery Process

Coal Tar Dewatering and Recovery
As a by-product of coke and gas produced by coking plants, coal tar has absolute practical value in industrial and medical
industries. In the tar extraction process, dehydration and solid removal effects will directly affect the purity of tar. The
purity of tar will directly affect its market value.

SZ decanter centrifuge has huge technical advantages in the recovery process of coal tar. Because we have more than 20 years of experience and technology precipitation in industrial centrifuges, SZ coal tar decanter can be used in the dehydration and solid separation process in the tar recovery process of the coking plant. It can effectively separate solid impurities and water from the tar and extract high-purity tar. Simultaneously, our equipment has the characteristics of anti-wear protection and continuous operation and is equipped with an automated control unit, which can significantly reduce the labor operation cost and save the company the most considerable degree of production and operation costs.

Scope of application:

Coal tar recovery

Coal tar is a dark brown, viscous liquid produced when the coal is distilled off. The yield rate of coal tar is usually at 3-4% of the dry coal. According to different coking temperatures, coal tar can be divided into high-temperature tar, intermediate
temperate and low temperature tar. According to different pyrolysis temperate, it can be divided into low temperature (450 ℃ ~ 650 ℃) dry distillation tar, low and medium temperature (600 ℃ ~ 800 ℃) furnace tar, Medium temperature (900 ℃ ~ 1000 ℃) vertical coal tar, high temperature (1000 ℃) coking tar. The crude tar is produced by the coking process with circulating ammonia spray gas and condensate cooling in the primary cooler, containing about 4% water, and sometimes up to 8 to 10%.

Ammonia Coal Tar Solids

The heavy liquid phase separated by the centrifuge can adopt two different liquid discharging modes, namely gravity discharging and discharging through the built-in centripetal pump with pressure, wherein the latter includes liquid layer fixed mode and the online adjustable mode of heavy phase liquid layer, which is selected according to the process conditions.

★ Separation performance (typical medium and high temperature coal tar) of coal tar three-phase centrifuge:

1. The centrifuge features high separation efficiency, compact structure, and continuous operation. The diameter of the separated particles can be reduced to 2 μm. The solid content (toluene insoluble matter) in the treated coke button is more than 45%, which can easily optimize the clarification of liquid and the dryness of solids.

2. Tar quality after separation: aqueous ammonia content: <2.5%; tar content: ≥97%; solid content (> 100 μm): <0.3%

3. After separation, the tar in the aqueous ammonia: ≤ 4g/L

Note: The aforementioned separation performances are based on coal tar temperature of 270°C.

Working Principle

1. The centrifuge features high separation efficiency, compact structure, and continuous operation. The diameter of the separated particles can be reduced to 2 μm. The solid content (toluene insoluble matter) in the treated coke button is more than 45%, which can easily optimize the clarification of liquid and the dryness of solids.
2. Tar quality after separation: aqueous ammonia content: <2.5%; tar content: ≥97%; solid content (> 100 μm): <0.3%.
3. After separation, the tar in the aqueous ammonia: ≤ 4g/L.

1)The machine starts and speeds up automatically.
2)When the proper working condition are met and the revolving drum reaches the feeding speed,the feeding valve opens and allows suspension which will be separated to enter into the product compartment of the spiral feeder through the feeding pipe.
3)After the preliminary speed-up,the suspension passes the outlet of compartment and into the drum.Because of centrifugal force, the suspension in the drum is quickly divided into two phases;the heavier solid phase deposits to the inner wall of the drum and driven by the differential gear which results in the non-cynchronous movement between the spiral feeder and the drum,the solid phase will be transferred into the small end for further dehydration and finally discharged through solid phase outlet.
4)The separated liquid flows out though the big end or will be driven out by centrifugal pump.

SZ decanter can run continuously and automatically. The control of the decanter centrifuge is completed through the touch screen of the control panel, and the one-key start and stop of the decanter can be realized through the control panel. The control panel interface is simple and easy to be understood, and operators can easily monitor the working status and understand the operating parameters.

Lubrication Ways

In order to meet the actual needs of different customers, SZ decanter centrifuge provide three different lubrication ways (grease pump grease lubrication, lubricating oil circulating lubrication and oil mist lubrication) for customers to choose. All lubrication systems can re-lubricate the rotor bearings during centrifuge operation.

Safety and Security

SZ decanter differential speed automatic control technology can automatically adjust the screw conveyor differential speed, to prevent overload and blockage. At the same time, SZ decanter centrifuge has vibration protection, bearing temperature protection and overload protection system.
