Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature carbonization furnaces, and more specifically, to a high-temperature carbonization furnace with auxiliary nitrogen cooling. Background Art

[0002] There are three types of carbonization furnaces: ordinary type (can only be used to produce charcoal, cannot collect gas); wood carbonization equipment (used to carbonize branches, wood blocks, coconut shell blocks, scrap blocks from furniture factories, etc. This equipment can be equipped with a gasification furnace to recycle gas into gas for the carbonization furnace itself or other use); carbon powder production line (a machine used to produce carbon powder, which can carbonize rice husks, sawdust, and bamboo dust into carbon powder, which can be processed into activated carbon); high-temperature carbonization furnace, which distills and carbonizes carbon-containing wood materials (granular in size less than 15mm) such as sawdust, rice husks, peanut shells, plant straw, and bark under high temperature conditions in the furnace, and has an oxygen-free carbonization rate. This series of charcoal machine equipment has a high carbonization rate.

[0003] Among them, after searching, it was found that the patent application number CN202221568975.0 discloses a high-temperature carbonization furnace, including: an incinerator, a furnace wall is fixedly installed inside the incinerator, a water-cooling pipe is fixedly installed on the inner surface wall of the furnace wall, the output end and input end of the water-cooling pipe both pass through the top of the incinerator of the furnace wall, the input end of the water-cooling pipe is fixedly connected to a water pump, the input end of the water pump is fixedly connected to a water pipe, the input end of the water pipe is fixedly connected to a water tower, the input end of the water tower is fixedly connected to a water inlet pipe, and the input end of the water inlet pipe is fixedly connected to the output end of the water-cooling pipe;

[0004] When this structure is in use, the cooling water in the water tower is taken in, and the cooling water then enters the water cooling pipe through the water delivery pipe. The cooling water circulates in the water cooling pipe once and is then delivered to the water tower through the water inlet pipe. In this way, the cooling water forms a cycle in the water cooling pipe. During the circulation of the cooling water, the heat of the furnace wall will be continuously taken away, thereby cooling the furnace wall. However, the cooling efficiency of a single water circulation is low, and it is not easy to recycle the heat generated by the combustion in the carbonization furnace. Utility Model Content

The pump 12 is started to drive the worm gear 10 to operate and transport nitrogen through the reinforcement tube 9 to the diversion tube 7. After being diverted by the diversion tube 7, it is ejected from the nozzle 8. Nitrogen, as an inert gas, does not react with carbon at high temperatures, can quickly reduce the temperature in the furnace and protect the carbonized product from oxidation or other damage. The specific structural configuration of the component is as follows;

[0023] The heat exchange cooling assembly includes a furnace body 2 arranged on the top of the base 1, a heat exchange cavity 3 is arranged on the top of the furnace body 2, an inner lining frame 4 is arranged between the furnace body 2 and the heat exchange cavity 3, and a heat exchange tube 5 is arranged in the heat exchange cavity 3;

[0024] A plurality of diversion tubes 7 are provided on the top of the heat exchange tube 5, and a plurality of nozzles 8 are provided at the bottom of each diversion tube 7. A reinforcement tube 9 is provided on the outside of the furnace body 2. The reinforcement tube 9 passes through the heat exchange cavity 3 and extends to the diversion tube 7. The reinforcement tube 9 is connected to the diversion tube 7. A worm gear 10 is provided at the bottom of the reinforcement tube 9. A connecting tube 11 is provided at one end of the worm gear 10.

[0026] According to the above structure, when the device is used, the staff installs the device at the designated position. When the high-temperature heat generated by the combustion of the furnace body 2 diffuses upward, it is heat-conducted and heat-exchanged through the heat exchange tube 5, realizing the function of heat recovery and utilization, and at the same time reducing the heat of the smoke when it is discharged;

[0027] At the same time, when cooling, the staff installed the nitrogen device in the furnace body 2 and connected the nitrogen device to the connecting pipe 11. The pump 12 was started to drive the worm gear 10 to transport the nitrogen through the reinforcement pipe 9 to the diversion pipe 7. After being diverted through the diversion pipe 7, the nitrogen was ejected from the nozzle 8. As an inert gas, nitrogen will not react with carbon at high temperature, so it can quickly reduce the temperature in the furnace and protect the carbonized products from oxidation or other damage.

[0028] Different from the prior art, the present application discloses a high-temperature carbonization furnace with auxiliary nitrogen cooling. Heat conduction and heat exchange are carried out through the heat exchange tube 5 to realize the function of heat recovery and utilization, and at the same time, the heat of the flue gas is reduced. The pump 12 is started to drive the worm gear 10 to operate and transport nitrogen through the reinforcement tube 9 to the diversion tube 7. After being diverted by the diversion tube 7, it is ejected from the nozzle 8. Nitrogen, as an inert gas, will not react with carbon at high temperature, and can quickly reduce the temperature in the furnace and protect the carbonized product from oxidation or other damage.

[0029] At the same time, the driving motor 15 starts to drive the fan 16 to rotate, and the fan 16 rotates to exhaust the smoke in the furnace body 2.
