Combined combustion energy conversion flue-cured tobacco furnace

Abstract

A combined combustion energy conversion flue-cured tobacco furnace comprises a heat reaction furnace, a heat exchange mechanism and a smoke exhaust mechanism. An annular air supply duct is arranged at the middle lower portion of a vaporizing chamber circumferentially and horizontally. Air supply holes are evenly arranged around the air supply duct which is connected with a draught fan through an air supply pipe penetrating through the wall of the vaporizing chamber. A heat energy nozzle is arranged on the lateral wall of the vaporizing chamber, one end of the heat energy nozzle extending out of the vaporizing chamber is connected with a sealed combustion chamber which is communicated with the vaporizing chamber through the heat energy nozzle, and an air inlet is arranged on the lateral wall of the combustion chamber. A left direction adjustment chamber is communicated with a right direction adjustment chamber through a radiation pipe, and the upper portion of the right direction adjustment chamber is drained through a smoke collecting pipe and a smoke exhaust pipe. The combined combustion energy conversion flue-cured tobacco furnace is high in heat efficiency and adapts to vaporization of high-quality coal and vaporization of wood coal and biomass briquettes. The solid fuel has a wide application range, and discharged ash serves as optimal raw materials of biomass fertilizers.

Description

[0001] technical field [0002] The invention relates to a thermal energy conversion device used in the tobacco industry, in particular to a flue-cured tobacco furnace which continuously converts thermal energy through solid fuel combustion and gasification combustion. Background technique [0003] Tobacco planting bases are generally set up in mountainous or hilly areas, and tobacco-curing rooms are scattered outside the village. Under the unified management of the State Tobacco Monopoly Bureau, the size of the curing rooms has been standardized, and the flue-curing ovens have also followed the national energy-saving and emission-reduction requirements. Unified update every year. The existing flue-cured furnace is a cylindrical body, the front of the cylindrical body is designed with a feed door and an ash outlet door up and down, a furnace grate is arranged above the ash outlet door in the cylinder body, and the air blower sends air into the furnace from the side of the as...

AI Technical Summary

Problems solved by technology

In practice, it is found that the existing flue-cured tobacco furnace has the following disadvantages: 1. The natural gaps in the grate cause all the unburned fixed carbon to fall, wasting energy; The one-time feeding amount of the gasifier is limited to the use of high-quality coal, and it is impossible to use firewood coal or biomass briquette flue-cured tobacco, and the fuel is suitable for a single variety; 4. The service life of the grate is short, and the replacement cost is high
