Abstract

The utility model belongs to an agitated reactor for chemical industry, which comprises a reactor body with a concave reactor bottom, a stirring mechanism with corresponding structure, a jacket, an annular smoke chamber arranged between the side wall jacket and a side wall of the reactor body, a supporting seat arranged at the lower end of the side wall jacket, a feed inlet, a tap hole, and an oil outlet assembly seat. The agitated reactor has the characteristics of uniform heating of the reactor body for cracking waste and old plastics, difficult deformation of the reactor bottom, long service life, convenient and clean slag removal, higher thermal efficiency and productivity, etc. The defects that when a flat bottom and a convex bottom agitated reactors are used for cracking plastics, the reactor bottom is easy to deform and burn out; slag is difficult to remove and remove away; the thermal efficiency and the productivity are lower, etc. are overcome.

Description

A kind of reactor

The utility model belongs to a kind of chemical industry reactor, and particularly a kind of cracking waste or used plastics that can be used for is to produce the reactor of fuel oil.

Utilizing waste or used plastics to produce in the industry of fuel oil, the popular response still of employing generally comprises the kettle of band insulation jacket, at the bottom of the still of flat or outside protrusion.Because the plastics thermal conductivity factor is extremely low, guarantee temperature in the cracking still about 400 ℃ and will keep certain productivity ratio, the temperature at the bottom of the still generally need reach 800 ℃～1000 ℃; Leave residue behind the plastic cracking, cambered outwards still base residue is sunken to the bottom, is difficult for discharging; The effect that adds medium and stirring power at the bottom of the still in the part under the condition of high temperature easily produces " creep " distortion again; And moderate finite deformation also very easily takes place in flat still under this hot conditions, and stirring can not normally be carried out, last residue also can not go out to the greatest extent, general all have the thick residue in the about 15mm of one deck left and right sides topped at the bottom of the still, this class residue thermal resistance is very big, reduce the speed that heats up in the still again, both consumed energy, influenced its generation rate again; More seriously local temperature is too high and inhomogeneous at the bottom of the still, burns out at the bottom of causing still, and what influence was produced normally carries out.Therefore, the popular response still is used for the cracking waste or used plastics, and to exist kettle to be heated inhomogeneous to produce fuel oil, yielding at the bottom of the still, burn out, deslagging difficulty, defective such as productivity ratio and hot productive rate are lower.

The purpose of this utility model is to be used for the existing disadvantage of waste or used plastics cracking at aforesaid reaction vessel, design a kind of with at the bottom of the special-shaped still and the reactor of special-shaped agitator, it is reached when utilizing this reactor heating pyrolyze waste or used plastics, kettle is heated evenly, not yielding at the bottom of the still, long service life, reaction back residue-discharge convenience, clean improves purposes such as the thermal efficiency and productivity ratio simultaneously.

Solution of the present utility model be with to change at the bottom of evagination or the flat still be made as the arc still that inwardly concaves at the bottom of, to enlarge heating surface and to solve the structural defect that Yin Gaowen is yielding and residue is difficult for draining, simultaneously counterpart at the bottom of puddle support and the still also is designed to corresponding spill and stirs and the effect of slagging tap to improve; Set up again between this external kettle sidewall chuck and the kettle sidewall an annular smoke chamber when the flame in the burner hearth and high-temperature flue gas enter heat-exchanging chamber to still at the bottom of after the heating, export the annular smoke chamber that enters between chuck sidewall and the kettle through tail flue gas again, again the kettle sidewall is heated, kettle was heated evenly, had improved its thermal efficiency again.Therefore, the utility model comprises the reactor body, is located at kettle outer chuck, puddle support and actuating unit thereof; At the bottom of key was at the bottom of the reactor still to be the arc still that inwardly concaves, its puddle support also should be the spill puddle support mutually, and the sidewall chuck of kettle then for the annular chuck of band housing, also is provided with smoke chamber between this chuck and the kettle; Strike up partnership with the sealed weldering of kettle side wall lower ends at the bottom of the still, the sidewall chuck then is anchored on the kettle side roof part by its inside and outside shell.Also be provided with fuel-displaced assembly seat at the top of this reaction.All concentrate at the bottom of the still and influence its use and life-span for fear of the dead load of whole kettle and auxiliary equipment thereof and dynamic load, also do not have supporting base at the circular bottom part of sidewall chuck, with quiet, the dynamic load of the supporting kettle overwhelming majority.And described at the bottom of the arc still that kettle is recessed, be preferably at the bottom of this still at the bottom of the standard ellipse curved surface still.

The utility model is owing to reach corresponding puddle support and be concave shaped at the bottom of the still, thereby both overcome inhomogeneous and yielding and deslagging is difficult and the defective that is difficult for draining because of high-temperature heating effectively.That entire reaction still body is heated is more even and set up annular smoke chamber between kettle sidewall chuck and reactor sidewall, and has improved hot productive rate.Therefore this practical when having work the reactor body be heated evenly, not yielding at the bottom of the still, long service life, residue-discharge convenience, clean, the thermal efficiency and productivity ratio are than characteristics such as height.
