Problems solved by technology

[0004] Aiming at the two major problems of air intake and energy gathering, the present invention provides a cyclone-type multi-layer air intake hood installed in a biomass combustion furnace that not only lights up and gathers energy, but also cracks and burns tar and water vapor. The cyclone-type multi-layer air intake hood adopts multi-layer masks overlapping, no fan is needed, and the air is self-inhaled. The inner wall of the mask is equipped with cyclone blades, so that the air enters the fire hole to generate a rotating airflow. Aggregate to form a larger high-temperature zone, and the tar and water vapor coming out of the fire hole are cracked and burned at high temperature, generating huge heat and improving thermal efficiency, which better solves the problem of incomplete combustion of biomass stoves. The problem of low thermal efficiency due to non-concentrated firepower

Embodiment Construction

[0012] As shown in Figure 1, a cyclone-type multi-layer intake hood installed in a biomass combustion furnace is formed by overlapping multi-layer masks, the face wall (3) is upward, and a fire hole (1) is provided in the center, and the overlapping masks form multiple layers. Layer air inlet (5), the mask shape is arc mask, cone mask, pyramid mask, ellipse mask, parabolic mask. In order to prevent movement, positioning and fixing are adopted between the masks.

[0013] As shown in Figure 2, the inner wall (4) of the mask is evenly equipped with whirlwind blades (2), so that when the airflow enters the fire hole, a whirlwind effect is generated upward.

Abstract

A cyclone-type multi-layer air intake hood installed in a biomass combustion furnace, which includes a face mask and cyclone blades, is characterized in that the multi-layer air intake hood is composed of two or more than two face masks, and a fire hole is arranged in the center. The cyclone blades are evenly installed on the inner wall of the mask. The whirlwind blades are linear or arc-shaped, uniformly distributed obliquely with the fire holes, and the surface of the whirlwind blades is installed at a certain angle with the inner wall of the mask. The mask overlaps with the mask to form a multi-layer air inlet. The invention has simple structure, scientific air intake mode, remarkable energy gathering effect, can promote pyrolysis and combustion of tar and steam, improves thermal efficiency, reduces consumption of biomass energy, and reduces carbon emission. The invention is suitable for biomass burning stoves.

Description

technical field [0001] The invention relates to a device in a biomass combustion furnace, in particular to a cyclone-type multi-layer air intake hood installed in a biomass combustion furnace which not only lights up and gathers energy, but also cracks and burns tar and water vapor. Background technique [0002] At present, the combustion effect of all biomass direct-fired stoves used is not ideal, and there are defects such as incomplete combustion, excessive smoke and dust, no energy gathering, and no energy saving. Therefore, the popularization rate in rural areas is not high. The main reason is that the two problems of air intake and energy gathering have not been solved. It is undeniable that the use of the secondary air intake device has a good effect on biomass combustion, but the lack of energy gathering is still exposed during use, and the firepower is not strong. The biomass direct-fired furnace that performs secondary air distribution through the fan forcefully r...
