Embodiment Construction

[0014] As shown in Figure 1, the waste plastic 4 containing moisture first enters the drying tank 31 to remove most of the moisture, and then enters the front thermal cracking reactor 3 in the two sets of thermal cracking reactors, and the liquid phase part of the preceding thermal cracking reactor 3 The outer wall of the reactor is heated by a heat source 15 directly or indirectly heated by a flame, and the front pyrolysis reactor 3 has outer wall fins 5 and inner wall fins 9, which can increase heat transfer intensity and improve the rigidity of the still wall. The waste plastic 4 melts into a liquid after entering the front pyrolysis reactor 3, and a small amount of pyrolysis reaction takes place. The oil and gas discharged from the pre-pyrolysis reactor 1 enters one of two or more sets of gas phase main process equipment through two or more parallel pipelines. The gas phase main process equipment can be a catalytic and condensation system, and the catalytic and condensation...

Abstract

A full-load durably running apparatus for preparing gasoline and diesel oil by cracking rejected plastics is composed of more than one thermocracking reactors connected serially, a residue tank able to control the stay time of residual oil and separating oil from carbon black and solid impurities from oil, a gas plate routing unit, more than one pipelines connected parallelly, and the wall scrapers for the inner surfaces of said all units.

Description

Technical field [0001] The invention relates to a waste plastic pyrolysis oil production device, in particular to a waste plastic pyrolysis gasoline and diesel device capable of long-term full-load operation. Background technique [0002] The existing technologies for producing diesel oil and gasoline by cracking waste plastics have the following technical problems: (1) equipment and pipelines are easily blocked; (2) heat transfer surfaces are easily fouled to reduce heat transfer efficiency. The result is that the plant cannot run at full capacity for long periods of time. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, to provide a waste plastic pyrolysis gasoline and diesel device capable of long-term full-load operation, using this method to significantly reduce or prevent clogging, and the factory can be free of clogging after clogging occurs. Shut down to clear the blockage; the hea...
