Abstract

The invention discloses a process and complete equipment for pretreating coal tar. The complete equipment are an integrated pretreatment system jointly formed by a coal tar raw material storage tank (1), a three-phase centrifugal machine (3), an automatic back wash filter (5), a primary high-voltage electric field knockout drum (6), a secondary high-voltage electric field knockout drum (7) and the like. The process and complete equipment provided by the invention are suitable for the process requirements for large-scale deep pretreatment desalination, dehydration and impurity removal in a modern coal tar deep processing industry. The processing effects of the two-stage electric field knockout drums are greatly improved by using a high-voltage impulse power supply.

Description

technical field [0001] The invention relates to the field of deep processing and utilization of coal tar resources, and provides a process method and a complete set of equipment for large-scale centralized pretreatment of coal tar, so that the treated coal tar can meet the requirements of subsequent deep processing technology. Background technique [0002] Coal tar is one of the important products of the coking industry, and its composition is extremely complex. It is estimated that there are more than 10,000 kinds of organic compounds in coal tar, and about 500 kinds have been identified, which is a very complex mixture. [0003] From 2004 to 2007, the average annual growth rate of China's coal tar production was 17.5%. In 2007, China's tar consumption was 8.6 million tons, of which 5.2 million tons were used for deep processing, accounting for 60.5% of the total tar consumption. By 2010, China's coal tar output is expected to be about 10.7 million tons. With the develop...
