Abstract
The invention provides a coal pitch delayed coking and industrial naphthalene rectification combined naphthalene extracting device and relates to an industrial naphthalene extracting device. The device consists of a high-temperature coal tar tank, a No.1 distillation tower, a No.2 distillation tower, a delayed coking heating furnace, a coking tower, a fractionating tower, an industrial naphthalene distillation prefractionation tower and an industrial naphthalene distillation rectifying tower, wherein a carbolic oil and naphthalene oil pipeline outlet is formed in the upper part of the No.1 distillation tower; a scrubbing oil and anthracene oil pipeline outlet is formed in the upper part of the No.2 distillation tower; a delayed coke pipeline outlet is formed in the coking tower; an industrial naphthalene pipeline outlet is formed in the bottom of the industrial naphthalene distillation rectifying tower. Due to combination of single production processes and systems of raw material industrial naphthalene and high-temperature coal tar distillation, pitch delayed coking and industrial naphthalene rectification and naphthalene extraction, the problem that raw materials, byproducts, heat energy, electric energy and time are not utilized comprehensively in the processes of refining chemical materials and producing chemical products by a single system is solved, and equipment and places are utilized optimally. The obtained benefit is not just the disguised economic benefit obtained from comprehensive utilization.
