Forced guiding multistage rotation pressing flame ash separating structure for cooking furnace

Abstract

The invention relates to a forced guiding multistage rotation pressing flame ash separating structure for a cooking furnace. The forced guiding multistage rotation pressing flame ash separating structure comprises a flame collecting box which is in a cavity ring shape. A cavity second-stage flow guiding ring used for guiding the moving direction of flames communicates with the upper portion of the flame collecting box. A first-stage flow guiding plate used for scattering the flames is arranged between the second-stage flow guiding ring and the flame collecting box. The position of an inner opening of the flame collecting box is shielded through the first-stage flow guiding plate. Due to the graded flow guiding of the first-grade flow guiding plate and the second-stage flow guiding plate, light ash contained in the flames can be thoroughly knocked off, and the structure can be applied and popularized in any industry needing cooking, usable scenes the same as traditional energy such as electric heat, gas, fuel, fire coal and the like are available, and the structure has the larger excellence in the aspects of safety, flexibility and energy loss ratios. An opened type natural convection semi-gasification combustion manner is adopted, heat energy is directly transmitted to a container for heating to the maximum, forced flow guiding through an induced draught fan is avoided, heat energy cannot be lost, and the heat exchange efficiency is greatly improved.

Description

technical field [0001] The present application relates to a soot cleaning structure, in particular to a forced-guided multi-stage rotary pressing fire ash separation structure for cooking stoves used in cooking stoves. Background technique [0002] In the prior art, there are a variety of combustion devices using biomass fuels. These devices have improved the slag removal and air supply to a certain extent, so that the thermal efficiency has increased, but none of them has treated the small amount of light weight contained in the hot air flow. Most of the light ash generated after combustion will be discharged from the flue through the air-inducing device, and the other part will be discharged from the pot circle with the flame, thus causing a certain degree of indoor pollution.

Problems solved by technology

[0002] In the prior art, there are a variety of combustion devices using biomass fuels. These devices have improved the slag removal and air supply to a certain extent, so that the thermal efficiency has increased, but none of them has treated the small amount of light weight contained in the hot gas stream. Most of the light ash generated after combustion will be discharged from the flue through the air-inducing device, and the other part will be discharged from the pot circle with the flame, thus causing a certain degree of pollution to the room

At the same time, due to the existence of the air induction device, part of the heat is bound to be lost, resulting in a reduction in the thermal efficiency of finishing.

[0003] To sum up, although the combustion device in the prior art is low in use cost and its thermal efficiency can meet daily use, it still has certain limitations because it does not treat the ash that can be discharged into the air.
