Abstract

The invention discloses a direct biomass fuel hot air furnace including high-temperature purification unit. The hot air furnace comprises a burner, a high-temperature purification unit and an air mixing unit. The burner is structured into fuel burning to generate high-temperature flue gas. The high-temperature purification unit is structured into receiving high-temperature flue gas from the burner and removing particle dust included in high-temperature flue gas. The air mixing unit is structured into mixing of the high-temperature flue gas from the secondary combustion chamber with external air to produce hot air for drying materials. A plurality of retaining walls are arranged in the high-temperature purification unit to cause the high-temperature flue gas from the burner to produce rotational flows in the high-temperature purification unit and to become red and sticky to capture the particle dust included in the high-temperature flue gas when the temperature exceeds 1000 DEG C.

Description

technical field [0001] The present invention generally relates to a hot blast stove, and in particular, relates to a direct biomass fuel hot blast stove, which includes a high temperature purification device for dedusting high temperature flue gas. Background technique [0002] Through long-term production practice, people have realized that only by using hot air as the medium and carrier can the heat utilization rate and thermal work effect be greatly improved. As a thermal power mechanical hot blast stove, it began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. The direct-type or direct-fired biomass fuel hot air stove uses fuel to burn directly, and forms hot air after high-purification treatment. The hot air directly contacts with the material to be dried to realize heating, drying or baking. Using a direct hot blast stove, the fuel consumption ...
