Cooking stove forced guiding multigrade convolution suppression flame ash separation structure

Abstract

The invention relates to a cooking stove forced guiding multigrade convolution suppression flame ash separation structure comprising a flame collecting box. The flame collecting box is in a cavity annular shape, the upper portion of the flame collecting box communicates with a cavity second-grade flow guiding ring for guiding the direction of flame, a first-grade flow guiding plate for dispersingthe flame is arranged between the second-grade flow guiding ring and the flame collecting box, and the first-grade flow guiding plate is shielded at an inner opening of the flame collecting box. According to the cooking stove forced guiding multigrade convolution suppression flame ash separation structure, through grading flow guiding of the first-grade flow guiding plate and the second-grade flowguiding ring, light ash slag contained in the flame can be knocked off thoroughly, and the cooking stove forced guiding multigrade convolution suppression flame ash separation structure can be applied and popularized in any industries needing cooking, has the useable scenarios the same as conventional energy sources such as electric heat, fuel gas, fuel oil and fuel coal, and has greater excellence in the aspects of safety, flexibility and energy consumption ratio; and the cooking stove forced guiding multigrade convolution suppression flame ash separation structure adopts an open natural convection semi-gasification combustion mode, heat energy is directly conducted to a container maximally for heating, the situation that the heat energy is lost due to forced flow guiding of an induced draft fan is avoided, and the heat exchanging rate is increased substantially.

Description

technical field [0001] The present application relates to an ash cleaning structure, in particular to a forced-guided multi-stage rotary pressing fire ash separation structure for a cooking stove. 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. At the same time, due to the existence of the air-inducing device, a part of heat is bound to be lost, resulting in a reduction in the thermal efficiency of finishing.

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.
