technical field

The utility model relates to the field of new energy sources, in particular to a wind pressure knock-down structure of a discharge port of a biomass particle wind throwing machine.

Background technique

The research and development of bioenergy technology has become one of the world's major hot topics, and has attracted the attention of governments and scientists around the world. Many countries have formulated corresponding development and research plans, such as the Sunshine Project in Japan, the Green Energy Project in India, and the Energy Farm in the United States, among which the development and utilization of bioenergy occupies a considerable share. Many foreign bioenergy technologies and devices have reached the level of commercial application. Compared with other biomass energy technologies, biomass pellet fuel technology is easier to achieve large-scale production and use. The convenience of using bioenergy particles is comparable to energy such as gas and oil. However, the current biomass pellet machines have some deficiencies, especially in terms of combustion efficiency. Because the biomass particles are directly poured from the discharge port into the center of the machine to form accumulations, the contact area is often too small, insufficient combustion, and residues excessive.

Utility model content

The purpose of this utility model is to aim at the defects and insufficiencies of the prior art, and to provide a wind pressure break-up structure at the outlet of a biomass particle wind throwing machine. Disperse to make it evenly distributed, and increase the contact area, burn more fully and reduce residue.

In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: a kind of wind pressure break-up structure of the discharge port of biomass particle wind throwing machine, including a combustion chamber, an air inlet pipe, a discharge port, a chimney, and a screen; The chamber is a furnace structure made of refractory bricks. Inside the combustion chamber is a hollow space with a rounded table, and a through hole is provided at the bottom of the combustion chamber as an observation port, and a soot cleaning port connected to the combustion chamber cavity is provided below the observation port; One side of the combustion chamber is provided with a small round hole as an ignition port, and one side of the ignition port is provided with a large round hole as an air inlet; an air inlet pipe runs through the air inlet, and the air inlet pipe extends to the center of the combustion chamber It is bent and opened upwards, and the diameter of the opening is enlarged into a funnel shape; one side of the combustion chamber is provided with a discharge port that runs through the side wall of the combustion chamber, and the discharge port extends to the top of the air inlet pipe and bends downward to open; The top of the combustion chamber is provided with a chimney connected to the inner chamber of the combustion chamber, and a filter screen is arranged between the chimney and the combustion chamber; the top surface of the combustion chamber is connected with a screen suspender through bolts, and the bottom end of the screen suspender is connected with a disc Shaped screen, the screen is seamlessly covered around the funnel opening of the air inlet duct and welded.

Preferably, the air inlet duct is provided with three conical one-way dust-proof spacers facing the opening direction in the transverse duct in the combustion chamber.

The beneficial effects of the utility model are: the structure cooperates with the screen mesh through the air inlet pipe, and the biomass particles are scattered by the wind pressure to make them evenly distributed, and the contact area is increased, the combustion is more complete, and the residue is reduced.
