Problems solved by technology

[0007] The purpose of the present invention is to overcome the problem that tar residues are easy to block in the process of tar residues in the prior art, and to provide a fully automatic tar residue harmless treatment method; Ammonia water and steam are passed into the external ammonia water jacket to control the temperature in the liquefaction tank and reduce the viscosity of the tar residue. At the same time, the pipeline and equipment for tar residue transportation are preheated and washed to effectively ensure the smooth flow of the tar residue

Embodiment 1

[0033] A fully automatic tar residue harmless treatment system of this embodiment, combined with figure 1 , the system includes a liquefaction tank 1, a grinder 2, a transfer pump 3 and a centrifuge 4, wherein the liquefaction tank 1 is communicated with the mechanized clarification tank through a pipeline, so that the tar residue in the mechanized clarification tank can be easily transported to the liquefaction tank In 1, the liquefaction tank 1 is equipped with a stirring paddle for stirring and breaking the tar residue; the grinder 2 in this embodiment is connected to the liquefaction tank 1 through a conveying pipeline, and is used for the tar residue once broken from the liquefaction tank 1. Secondary crushing; the tar residue after secondary crushing is sent to the centrifuge 4 through the conveying pump 3, and the tar and the residue in the tar residue are separated from each other by the centrifuge 4, and the separated tar is sent to the mechanized clarification tank of...

Embodiment 2

[0053] A fully automatic tar residue harmless treatment method of the present embodiment is basically the same as Embodiment 1, and its difference is:

[0054] In step a in this embodiment, the stirring rate of the stirring paddle of the stirring system is 5 minutes per hour; the tar residue is stirred and broken by the stirring paddle in the stirring system, and the larger agglomerates are broken, that is, the tar The slag is crushed once to ensure that the tar residue in the liquefaction tank 1 is fully liquefied and crushed.

[0055] In step b, when the liquid level in the liquefaction tank 1 reaches 3 / 10, the steam purging pipeline is opened, and the tar residue in the pipeline and the tar residue remaining on the pipeline wall are blown into the liquefaction tank 1 .

[0056] In step c, when the liquid level in the liquefaction tank 1 reaches 3 / 5, then the centrifuge 4, the grinder 2 and the transfer pump 3 are turned on in sequence.

[0057] In step e, control the flush...

Embodiment 3

[0059] A fully automatic tar residue harmless treatment method of the present embodiment is basically the same as Embodiment 1, and its difference is:

[0060] In the present embodiment, in step a, the stirring rate of the stirring paddle is controlled to be 8 minutes per hour; in step b, when the liquid level in the liquefaction tank 1 reaches 7 / 20, the pipeline is purged with steam; in step c, the liquefaction tank is When the liquid level in 1 reaches 19 / 30, then turn on the centrifuge 4, the grinder 2 and the transfer pump 3 in turn; in step e, control the washing and cleaning time to be 6 minutes.

Abstract

The invention discloses an automatic tar residue harmless treatment method, which belongs to the technical field of tar residue treatment. The method firstly disintegrates the tar residue through a liquefaction tank, heats and stirs it, and transports it to a centrifuge with a pump after grinding, and separates the tar residue into tar and slag powder. Ammonia and steam are introduced into the liquefaction tank to control the temperature in the liquefaction tank, and the temperature is controlled at 65°C ± 3°C, which can reduce the viscosity of the tar residue. It can effectively ensure the smooth flow of tar residue and avoid the problem of tar residue blocking the pipeline.

Description

technical field [0001] The invention relates to the technical field of tar residue treatment, in particular to a fully automatic tar residue harmless treatment method. Background technique [0002] In the coking production process of the coking plant, the high-temperature coke oven gas produced is cooled by the gas collector or the primary cooler, and the high-boiling organic compounds are condensed to form coal tar. Coal tar is also mixed with coal tar to form lumps of different sizes, which are called tar residues. [0003] At present, the common method of utilization is to use it as a raw material for tar refining and coal blending, but the utilization rate is only about 30% of the generated amount, and most of the coal tar residue is still discarded as waste, which is very harmful to the environment. It occupies a large area, requires a large investment in the storage yard, and has high operating costs. It will also emit sulfur-containing compounds to pollute the enviro...
