An open dry distillation wood gas stove

Abstract

The invention discloses an open dry distillation wood gas stove, comprising a silo, a motor, a spiral auger, a furnace, a smoke-charcoal separator, a preheating igniter, a smoke extraction wind wheel, an L-shaped smoke delivery pipe, and a charcoal silo. The granular biomass fuel slides into the spiral auger from the silo, and the motor drives the spiral auger to deliver the fuel into the smoke-charcoal separator in the furnace. The preheating igniter heats the smoke-charcoal separator to dry distill the fuel inside to separate combustible gas and charcoal, and the charcoal is discharged into the charcoal silo. The combustible gas is ejected from the smoke extraction wind wheel through the L-shaped smoke delivery pipe, and the ejected combustible gas is ignited by the igniter to continue to heat the smoke-charcoal separator to form a self-sustaining cycle, and the preheating igniter can be turned off. Since the fuel is not directly burned, the invention has no dust pollution and is clean to use. Since all smoke is recycled and burned, it has super high combustion efficiency and little pollution to the environment. The combustion process does not require artificial feeding and is convenient to use. The ideal fuel of the invention is super reed that is processed into particles after being dried, so it has a promoting effect on carbon recovery.

The fuel is transported by the spiral auger (22) driven by the motor (21). A ventilation shutter (23) is installed on the outside of the machine room (2). The function of the ventilation shutter (23) is to dissipate heat for the motor (21). The other side of the machine room (2) is connected to a water tank (3). The function of the water tank (3) is to cool down the heat dissipation feeding pipe (31) to prevent the fuel from being induced into the fuel in the fuel tank (1) due to high temperature. A heat dissipation feeding pipe (31) is installed inside the water tank (3) and a water inlet (9) is installed on the outside. The heat dissipation feeding pipe (31) is a fuel transportation channel. The water inlet (9) is a water filling port of the water tank (3). The top of the water tank (3) is connected to a heat preservation tank (4). The heat preservation bin (4) can provide food insulation and provide heat for the furnace (5) to be dissipated to the outside, and has a certain heating function. A steam conduit (41) and an electric water pumping faucet (42) are respectively installed inside the heat preservation bin (4). The steam conduit (41) is connected to the water bin (3). The heat in the furnace (5) directly heats the water bin (3). Steam after the water boils is discharged into the heat preservation bin (4) through the steam conduit (41). The electric water pumping faucet (42) is connected to the water bin (3) and one end extends to the top of the heat preservation bin (4) and the other end extends to the bottom of the water bin.

A ventilation platform (53), an L-shaped smoke delivery pipe (59), a preheating igniter (58), a smoke and charcoal separator (57), a rotary baking rack (8), and a heat storage and fire hood (7) are installed inside the furnace (5). The rotary baking rack (8) is installed on the inner side of the top of the furnace (5) to provide a baking function. An exhaust pipe (54) is installed on the top of the furnace (5) and the exhaust pipe (54) is connected to the heat preservation bin (4) and the furnace (5) respectively. The exhaust pipe (54) is used to discharge water vapor and hot air in the water bin (3), the heat preservation bin (4) and the furnace (5).A pot rack (55) is installed on the top of the furnace (5) and is connected to the furnace (5). The pot rack (55) can allow the heat in the furnace (5) to heat a frying pan or other container to provide a stove function. A controller (56) is installed on the top of the furnace (5). The controller (56) is a switch for integrated control of live devices such as a motor (21), an electric water faucet (42), a preheating igniter (58) and a wind wheel motor (69). A fire viewing door (51) and an adjustable shutter air inlet window (52) are installed on one side of the furnace (5) and are connected to the furnace (5). The fire viewing door (51) can provide a fire-warming function. The adjustable shutter air inlet window (52) is an air inlet of the furnace (5). A charcoal bin (6) is connected to the other side of the furnace (5). The furnace (5) and the charcoal bin (6) The top of the charcoal bin (6) forms a plane to provide a working platform. A charcoal collecting plate (61), a charcoal discharge cover plate (63), a smoke delivery elbow (67), a smoke extraction fan wheel (66), a smoke delivery channel (64), a one-way air intake valve (65), and a smoke hanging rack (68) are installed inside the charcoal bin (6). When the fan motor (69) is not working and the smoke after dry distillation fills the entire charcoal bin (6), the smoke hanging rack (68) provides a smoke function for the charcoal bin. A charcoal bin sealing door (62) is installed on one side of the outside of the charcoal bin (6) and a fan motor (69) is installed on the other side. When the fan motor (69) is working, the one-way air intake valve (65) automatically opens due to the influence of negative pressure to inhale air, thereby preventing the fan motor (69) from being overloaded due to the negative pressure inside the charcoal bin (6).

[0013] The two ends of the heat dissipation feeding pipe (31) are respectively connected to the funnel support (11) and the feed port A (571) of the smoke-charcoal separator (57); the position of the end of the heat dissipation feeding pipe (31) connected to the funnel support (11) is lower than the position of the end connected to the feed port A (571); the spiral screw (22) is inserted into the heat dissipation feeding pipe (31) and its length does not exceed that of the heat dissipation feeding pipe (31); the smoke delivery end B (572) and the charcoal discharge end C (573) of the smoke-charcoal separator (57) are connected to the charcoal bin (6); the smoke delivery end B (572) is higher than the charcoal discharge end C (573), and the charcoal discharge end C (573) is higher than the feed port A (571); the smoke-charcoal separator (57) passes through the heat storage and fire setting cover (7). The advantage is that after the cyclic self-sustaining combustion is formed, the heat storage and fire setting hood (7) collects and stores most of the heat to accelerate the speed of the dry distillation reaction, so that the preheating furnace wire (581) can be turned off to achieve energy saving. The fuel passes through the spiral auger (22) and the heat dissipation feeding pipe (31) to reach the smoke and charcoal separator (57) to prepare for the dry distillation reaction. It should be noted that the feeding pipeline from the spiral auger (22), the heat dissipation feeding pipe (31), and the smoke and charcoal separator (57) is arranged from low to high. The advantage of this is to prevent the occurrence of smoke and fire back during dry distillation. The end of the spiral auger (22) does not exceed the heat dissipation feeding pipe (31) to prevent the high temperature of the furnace (5) from heating the spiral auger (22) and igniting the material.

[0014] The L-shaped smoke delivery pipe (59) is located at the bottom of the furnace (5) and passes through the charcoal bin (6) to communicate with the smoke delivery channel (64). The ventilation platform (53) is located above the L-shaped smoke delivery pipe (59) and is connected to the heat storage and fire setting cover (7). The preheating igniter (58) is connected to the ventilation platform (53) and is located inside the heat storage and fire setting cover (7). The ignition wire (582) of the preheating igniter (58) corresponds to the circular hole in the ventilation platform (53) and is aligned with the injection port (591) on the L-shaped smoke delivery pipe (59). The preheating wire (581) of the device (58) is on the periphery (582) of the ignition wire, and the combustible smoke is ejected through the ejection port (591) on the L-shaped smoke delivery pipe (59) through the circular hole of the ventilation platform (53) and ignited by the preheating wire (581) of the preheating igniter (58) to form a high-temperature jet flame. The flame temperature is collected and stored by the heat storage and setting fire cover (7) to heat the smoke and charcoal separator to form a dry distillation reaction. Since the entire preheating igniter (58) is in the heat storage and setting fire cover (7), the speed of the first heating can be increased.

[0015] The charcoal discharge cover plate (63) covers the charcoal discharge end C (573) of the smoke charcoal separator (57) and can be opened and closed freely. The charcoal discharge cover plate (63) can block the discharge of a portion of charcoal according to its own weight. When the fan motor (69) drives the smoke extraction fan wheel (66) to work, air enters the charcoal bin (6) through the one-way air inlet valve (65) and passes through the gap of the charcoal discharge cover plate (63) to form a smoldering reaction with the charcoal accumulated at the charcoal discharge end C (573) of the smoke charcoal separator (57) to generate combustible gas to improve the utilization rate of fuel. One end of the smoke delivery elbow (67) is connected to the smoke charcoal separator. The smoke delivery end B (572) of the separator (57) is connected and the other end is connected to the smoke extraction fan wheel (66). The smoke delivery curved pipe (67) is provided with a triangular hole (671). Air can enter through the triangular hole (671) to mix with the combustible smoke to make combustion more complete.
