Abstract

The present invention relates to a cyclone furnace using agricultural wastes as fuel, comprising an upper chamber and a lower combustion chamber in a longitudinal direction. A husk inlet is formed in the lower combustion chamber and an air inlet is formed in the upper chamber. A husk conveyor drives the husk into the lower combustion chamber through the husk inlet in a direction offsetting from the longitudinal axis of furnace body to form vortex by being burnt in the lower combustion chamber. Hot air flow generated by the combustion rises upward into the upper chamber. An air charging device supplies air into the upper chamber through the air inlet in a direction offsetting from the longitudinal axis of the furnace body to form a vortex therein, which forces the husk ashes formed by the combustion to move downward and thus preventing the ashes from rising into the upper chamber. The ash is then removed through an ash outlet formed in the lower combustion chamber, while the hot air flow, which is clean, moves outward through a hot air outlet formed in the top of the upper chamber.

Description

V. Description of the invention (/) The invention of the invention relates to a cyclone burner that uses agricultural waste as fuel, especially a kind of cyclone burner that can produce clean high-heat air and easy to clean up ash after burning agricultural waste. C, such as rice husks or husks of other crops, are wastes ordered after the crops are refined. Because they can replace diesel as a fairly economical fuel after drying, they are currently placed in agricultural wastes such as husks. The combustion furnace is used as fuel, and the heat generated after combustion is used to provide agricultural processing equipment such as rice dryers, hot air systems required for rice milling, steam boilers, and so on. Μ π, the design of a combustion furnace using Chenye waste as fuel. It is a furnace body with a combustion chamber. The fuel is disposed into the combustion chamber through the inlet on the side of the furnace to ignite and burn. The hot gas generated after combustion passes through The hot gas outlet at the top of the furnace body is discharged, and the burnt ash can be discharged through the ash furnace outlet at the bottom of the furnace body. However, although the aforementioned combustion furnace design can use agricultural waste fuel and has the economic benefits of waste reuse, the ash after combustion is completely accumulated at the bottom of the furnace body without cooling treatment, which makes it very difficult to clean up the ash, and The hot air generated after combustion always entrains ash and pollutes the hot air. Therefore, it must be filtered to provide other agricultural processing equipment for use. Moreover, during the combustion process, the stability control of the heat is quite difficult, causing the combustion. The inconvenience of the connection between the furnace and other heat-requiring agricultural processing equipment. Therefore, the main object of the present invention is to provide a "whirlwind combustion furnace using agricultural waste as fuel". By designing the combustion furnace, not only economical agricultural waste can be used as fuel, but also the double cyclones in the furnace can be used. The design makes the exhausted hot air very clean and can be directly supplied. For other agricultural processing, the paper size applies Chinese national standards (CN ^^ · (210x297 mm)

It is transported at an angle to form a whirlwind, thereby suppressing the ashes to settle downward after the chaff is burned, preventing the ashes from rising to the upper chamber (丄 2), allowing the clean hot air to be discharged through the hot air outlet (121), and the hot air guide (6 〇) The air blower (6 2) is discharged to the use end through the hot air duct (6 workers). The hull system that was introduced into the furnace body (丄 〇) through the chaff inlet (1 12) before entering the lower combustion chamber (丄 丄) in a whirlwind manner, and the size of the fire can be reduced by the lower combustion chamber (1 1). Adjust the height of the ash burnt layer at the bottom. When the flame is too low, unburned chaff will be contained in the discharged ash due to incomplete combustion. At this time, the ash sweeper (4 2) can be operated. When the ash piles up, the flame will increase; if the flame is too large, the ash will easily turn up with the hot whirlwind and emit ash, so the artillery of the lower combustion chamber (masonry) needs to be controlled under a proper size. In addition, when the furnace body (10) burns the chaff, the side wall of the lower burner Γ forms a high temperature. The set (50) located outside the lower combustion chamber (11) can be blocked by its air interlayer (5 2), and The fan (6 5) draws air from the air interlayer (5 2), so that the cold air enters the air interlayer (52) from the bottom end = the port (5 4), and the air flow (5 5) is used to extend the air flow.
