Description

Technical Field

[0001] This utility model relates to the field of biomass utilization equipment technology, specifically a device for deep removal of dust from high-temperature fuel gas. Background Technology

[0002] Biomass is the only renewable carbon source containing carbon, characterized by low sulfur content, abundant resources, permanent utilization, and no increase in the total CO2 cycle. Converting it into high-grade oil slurry and biochar through pyrolysis and gasification not only frees humanity from dependence on finite fossil resources but also provides a large amount of charcoal raw materials for markets such as activated carbon, barbecue charcoal, and capacitor charcoal.

[0003] Chinese patent discloses a gas purification device for a straw gasification furnace (application number 202123026318.1), including a cyclone separator, a high-temperature fan, a high-efficiency dust collector, a first heavy oil remover, a second heavy oil remover, and a drying tower. The cyclone separator is used to connect to the gas outlet of the straw gasification furnace, and the high-temperature fan is used to transport the gas to the high-efficiency dust collector. The first heavy oil remover is equipped with baffles and a barrier layer, which intersect to form a T-shaped structure. The barrier layer is filled with barrier balls. The second heavy oil remover is equipped with a feed pipe and a bubbling pipe. The feed pipe is connected to the bubbling pipe and is immersed in the liquid of the second heavy oil remover. The top of the second heavy oil remover is equipped with an outlet connected to the drying tower. However, it does not completely remove dust from the high-temperature gas, resulting in a sharp decrease in the filter life of the subsequent cleaning device and high production costs.
