Discharging and stirring system of vertical pyrolyzing furnace

Abstract

The invention discloses a novel discharging and stirring system of a vertical pyrolyzing furnace, belonging to the field of chemical equipment. The novel discharging and stirring system comprises a compaction mechanism, a stirring mechanism and a discharging mechanism which are sequentially arranged in a furnace body from top to bottom, wherein the compaction mechanism has compaction and flattening effects on materials in a compaction area of the compaction mechanism, can effectively prevent the materials in the furnace from being loosely distributed, and guarantees that the inner volume of the furnace is fully utilized; the stirring mechanism can play a role in stirring materials in the furnace to ensure uniform pyrolysis of the raw materials, and can also prevent the furnace from slagging to ensure normal operation of the system; and the discharging mechanism is used for uniformly discharging materials from the inside of the furnace to the outside during discharging, promotes uniformperforming of the pyrolysis process, does not have a discharging function when discharging is not carried out and can be matched with the stirring mechanism to form a double-stirring effect. In addition, a plurality of discharging openings are evenly distributed in the base of the furnace body, and discharging can be guaranteed to be timely and stable. Therefore, the problems that an existing pyrolyzing furnace is uneven in discharging and pyrolyzing, slagging occurs to the pyrolyzing furnace, small-density raw materials are distributed loosely in the pyrolyzing furnace and the like in the prior art are solved; and the practicability of the system is high.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a discharge stirring system for a vertical pyrolysis furnace. Background technique [0002] At present, the discharge method of the vertical pyrolysis furnace is mainly that the material falls to the discharge hopper by gravity, and then is transported by an external screw discharge device to realize the transportation of the material from the pyrolysis carbonization area in the furnace to the outside of the furnace. When the material is falling under the gravity inside the furnace body, there is uneven discharge, and it is difficult to ensure that the material falls evenly, which will lead to uneven carbonization; in addition, if slagging occurs in the discharge area, it will be blocked. The discharge port affects the normal operation of the equipment. [0003] The patent No. CN204111673U mentions a new type of biomass continuous pyrolysis furnace. Its structure from top to bo...
