This utility model discloses a liquid fuel combustion device with multiple oil channels and multiple ignition points. The combustion body consists of a base, a vaporization combustion cylinder, a cyclone air inlet cylinder, and an impeller air inlet channel. The base is provided with two or more oil inlets, which are evenly distributed along the circumference of the primary vaporization combustion chamber and are arranged along the tangent of the primary vaporization combustion chamber. Each oil inlet is provided with an ignition plug and an atomizing combustion net. Compared with the prior art, this embodiment can meet the needs of combustion devices with high fuel values ​​through the dual oil channel design, and does not require the use of an oil pump for pressurization. This effectively avoids the problem of poor atomization and dispersion due to excessively fast injection speed. Moreover, compared with a single oil inlet, the liquid fuel can be more evenly distributed on the annular combustion net, and can be better dispersed for combustion under the action of the cyclone. The ignition and heating process is also faster than with a single oil inlet.

An explosion-proof cyclone filter device relates to the field of waste gas treatment technology in monocrystalline silicon production. It includes: an inner cylinder; an outer cylinder fitted around the outer periphery of the inner cylinder, forming a sealed cooling chamber between them; a cooling water pipe installed within the cooling chamber and spirally coiled around the outer wall of the inner cylinder; and an air inlet pipe sealed and connected to the inner cylinder. The cooling water pipe extends from both ends of the outer cylinder, facilitating the introduction of cooling water. This rapidly reduces the temperature of the inner cylinder and red phosphorus dust to below the auto-ignition point of red phosphorus (260°C), thus eliminating the risk of spontaneous combustion of the red phosphorus dust due to high temperatures. Simultaneously, by introducing gas, the cooled red phosphorus dust in the inner cylinder undergoes an oxidation reaction with the gas, thereby achieving the harmless treatment of the red phosphorus dust. The combination of cooling and oxidation effectively prevents explosions during cleaning, thus avoiding damage to the cyclone filter and personal safety hazards to on-site personnel, and preventing fire accidents.
