Embodiment Construction

[0014] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0015] Such as figure 1 As shown, the operating system of the tar-ammonia water separation tank includes a tar-ammonia water tank, a cutting pump, a regulating valve, and a supercentrifuge, wherein there are two groups of the tar-ammonia water tank, a cutting pump, and a regulating valve, and one supercentrifuge.

[0016] The tank bottom of one tar ammonia water tank is connected with the supercentrifuge through a cutting pump and a regulating valve, and the tank bottom of the other tar ammonia water tank is connected with the supercentrifuge through another cutting pump and another regulating valve.

[0017] Two sets of tar ammonia water tanks are arranged side by side. Two sets of parallel treatment systems are formed, the two tar ammonia water tanks operate completely independently, and two...

Abstract

The invention discloses an operation system of a tar ammonia water separating tank. The operation system comprises two groups of tar ammonia water tanks, two groups of cutting pumps, two groups of adjusting valves and one super centrifuge, wherein the bottom of one tar ammonia water tank is connected with the super centrifuge through one cutting pump and one adjusting valve, and the bottom of the other tar ammonia water tank is connected with the super centrifuge through the other cutting pump and the other adjusting valve. The operation system of the tar ammonia water separating tank is reasonable in structure design and gives full play to the tar ammonia water separation capability, the water content of tar before super centrifugation is smaller than or equal to 4%, besides, the interfaces in the tanks are more stable, and the quality of ammonia water is improved.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to an operating system of a tar ammonia water separation tank. Background technique [0002] The current oil-ammonia-water separation system adopts the tank-in-tank process. Two tar-ammonia-water separation tanks are set up, but only one super centrifuge is operated, which brings great difficulty to the separate control interface of the tar-ammonia-water separation tank. Temporarily adopting the route of tar in series to ensure the stability of the interface of one of the separation tanks and the normal oil replenishment of the primary cooler, but at the expense of the settling capacity of a tar ammonia water separation tank, the precipitation of tar ammonia water is not sufficient, and the tar contains water before separation If it is too high, it will have a negative impact on tar quality and coke oven production. Contents of the invention [0003] Aiming at the ...
