Description

Technical Field

[0001] The utility model relates to the technical field of biomass combustion, in particular to a biomass heating device with high combustion efficiency. Background Art

[0002] The biomass combustion device is a biomass high-temperature cracking burner that uses organic biomass such as biomass particles as fuel. It is developed for the needs of heating and cooling. It uses the abundant corn stalks and other crop straws in the countryside as raw materials, which are pressed into pellet fuels with regular shapes and uniform sizes by molding equipment, and then efficiently burned and converted into thermal energy by a dedicated fully automatic pellet incinerator. The heat generated by the combustion is absorbed by the circulating water in the boiler.

[0003] Existing biomass combustion devices are subject to uneven fuel quality, resulting in relatively low combustion efficiency and low energy utilization. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a biomass heating device with high combustion efficiency to solve the problem of low biomass combustion efficiency.

[0005] Based on the above purpose, the utility model provides a biomass heating device with high combustion efficiency, comprising: a combustion box, a heat dissipation device is fixedly installed on one side of the combustion box, and a wind valve is fixedly installed on one end of the heat dissipation device away from the combustion box;

[0006] A combustion residue collection box is slidably mounted on the lower end of the combustion box body, a discharge grille is fixedly mounted on the upper end of the combustion residue collection box, a number of flamethrowers are evenly fixedly mounted between the discharge grille and the combustion residue collection box and on both sides of the inner wall of the combustion box body, an isolation plate is slidably connected to the upper end of the discharge grille, a space combustion chamber is formed between the isolation plate and the discharge grille, a cover plate is fixedly mounted on the top end of the combustion box body, a fuel placement chamber is formed between the isolation plate and the cover plate.

[0007] As an optional embodiment, a heat dissipation device is fixedly installed on one side of the combustion chamber, and the heat dissipation device includes a first-level heat dissipation pipe and a connecting box. A plurality of first-level heat dissipation pipes are evenly fixedly installed on one side, and the first-level heat dissipation pipe is rotatably connected to a combustion spacer near one end of the combustion chamber.

[0008] As an optional implementation, a speed reducer is fixedly connected to one end of the first-level heat dissipation pipe away from the combustion spacer.

[0009] As an optional implementation, a connection box is fixedly installed at one end of the first-level heat dissipation pipe close to the speed reducer, and a second-level heat dissipation pipe is fixedly installed at one end of the connection box away from the first-level heat dissipation pipe.

[0010] As an optional implementation, an exhaust gas collecting box is fixedly mounted on one end of the secondary heat dissipation pipe away from the connection box, and an air valve is fixedly mounted on the upper end of the exhaust gas collecting box.

[0011] As an optional implementation, high-temperature resistant and high-strength glass is fixedly installed on the side of the combustion chamber away from the first-level heat dissipation pipe.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model ignites and burns biomass through multiple flame-spraying devices on both sides. High-temperature resistant and high-strength glass is fixedly installed on the outside of the combustion chamber, and the combustion situation can be clearly observed from the outside. When the biomass is not fully burned, the flame-spraying device can be ignited to re-ignite the incompletely burned material, so that the biomass fuel is fully ignited and the combustion efficiency is improved.

[0014] 2. When the biomass burns in the combustion chamber, the air valve is operated to form a negative pressure in the internal space of the combustion chamber. The hot air and part of the flame will burn on the combustion spacer and the first-level heat dissipation pipe. The heat will diffuse outward through the first-level heat dissipation pipe. The speed reducer at the end of the first-level heat dissipation pipe reduces the air flow rate, thereby promoting the full combustion of the biomass inside the combustion chamber. The residual heat on the first-level heat dissipation pipe will flow into the second-level heat dissipation pipe through the connecting box for heat dissipation, thereby reducing heat loss and indirectly improving combustion efficiency. The exhaust gas will enter the exhaust gas collection box and be discharged to the outside through the air valve to maintain a good indoor environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In this way, the biomass is put into the fuel placement chamber 23 and the isolation plate 13 is pulled out. The biomass will enter the combustion chamber 22 and be placed on the discharge grid 21. Multiple flamethrowers 20 on both sides ignite and burn the biomass. High-temperature resistant and high-strength glass 12 is fixedly installed on the outside of the combustion chamber 22. The combustion situation can be clearly seen from the outside.

A plurality of first-level heat dissipation pipes 25 are evenly fixedly installed on one side of the combustion box body 1. The first-level heat dissipation pipe 25 is rotatably connected to a combustion spacer 24 at one end close to the combustion chamber 22, and a reduction plate 26 is fixedly connected to the first-level heat dissipation pipe 25 at one end away from the combustion spacer 24.

When the biomass burns in the combustion chamber 22, the air valve 3 is operated to make the internal space of the combustion chamber 22 Negative pressure is formed, and hot air and part of the flame will burn on the combustion spacer 24 and the first-level heat dissipation pipe 25. The heat will diffuse outward through the first-level heat dissipation pipe 25. The speed reducer 26 at the end of the first-level heat dissipation pipe 25 reduces the air flow rate, thereby promoting the full combustion of the biomass inside the combustion chamber 22. The residual heat on the first-level heat dissipation pipe 25 will flow into the second-level heat dissipation pipe 28 through the connecting box 27 for heat dissipation, thereby reducing heat loss and indirectly improving combustion efficiency.
