Problems solved by technology

At present, domestic chemical plants generally adopt the traditional dry method for deslagging of the regenerator in the crude benzene section of the chemical production workshop. Although this method can save the amount of washing oil, it is easy to cause aging of the dry slag and block the regenerator during the slag discharge process. The slag discharge pipeline deteriorates th

Abstract

The invention discloses a slagging device of a crude benzene regenerator and a slagging method. Tar is poured into a slag tank and mixed with washing oil from the regenerator, generated waste gas enters a spray tower and makes contact with circulating water to be condensed, condensate water enters a circulation water trough, and the waste gas which is not condensed is recycled; an outer delivery valve is opened, and the tar is delivered into a tar trough. By means of the slagging device of the crude benzene regenerator and the slagging method, the quality of the washing oil can be optimized, the using amount of steam is reduced, a slagging pipeline is prevented from being blocked, the waste gas originally discharged into air is recycled in a sealed container, and harm to the environment is reduced.

Description

technical field [0001] The invention relates to the field of washing oil regeneration in coking production, and relates to a slagging device and a slagging method for a crude benzene regenerator. Background technique [0002] The slag discharge in the crude benzene section of the chemical production workshop of the coking plant is based on the principle of controlling the quality of the washing oil and improving the recovery rate of crude benzene. In this operation, a part of the circulating washing oil is usually sent to the regenerator, and superheated steam is used for blowing steam, and the steamed oil gas enters the debenzene tower as a heat source, and the remaining polymer substances of the circulating washing oil are discharged as residues; the slag discharge of the regenerator usually has : 1. Steam purging method; 2. Oil washing and dissolving method; 3. Manual dredging method. At present, domestic chemical plants generally adopt the traditional dry method for des...
