Embodiment Construction
[0018] figure 2 , image 3 The shape and structure of the carbonization furnace of this embodiment are shown. Mainly include: 1 furnace top 6-20mm crushed coal inlet, 2 furnace wall, 3 gas collecting hood, 4 combustion fire hole, 5 slag discharge port, 6 water coke quenching large groove, 7 small grain coal moving downward dense area, 8th One layer of fire hole, 10 second layer of fire hole, 11 small coal loose carbonization area, R combustion chamber, T carbonization chamber. The top is the gas outlet and the raw gas gas collecting pipe, the lower part of the gas collecting pipe is connected with several gas collecting hoods 3, and the gas collecting hoods 3 are in the shape of an inverted funnel. The feed inlets are evenly distributed on the top of the furnace and correspond to the carbonization chambers T at the bottom of the furnace. There are several carbonization chambers T evenly distributed on the bottom of the furnace, and the combustion chamber R and the carboniza...

The invention relates to a vertical internal thermal hollow carbonization furnace which mainly comprises a furnace wall, combustion chambers, a carbonization chamber, a gas collection cover and combustion chamber flame holes, wherein the carbonization chamber forms a shape and a structure with a narrow top and a wide bottom, and the upper ends of the walls of the carbonization chambers are in a multi-stage inverted ladder shape; a horizontal distance between flame observation holes on the same layer or with the same height of the two adjacent combustion chambers is gradually reduced from the top to the bottom; and the combustion chamber flame holes are respectively hidden on each layer of inversed ladders. The invention ends the history that small-particle coal cannot be used in the vertical internal thermal hollow carbonization furnace, better solves the problems of poor air permeability and easy flame hole blockage of the small-particle coal in the carbonization chamber, and obtainsgood effects of increasing the production and the efficiency, saving energy and reducing emissions.
Description
technical field [0001] The invention relates to the furnace body structure technology of a carbonization furnace in the semi-coke industry. Background technique [0002] Shenmu County in northern Shaanxi is rich in coal resources, and it is high-quality low-ash, low-sulfur, low-phosphorus, medium-to-high calorific value chemical coal, which is a high-quality raw material for the production of semi-coke. Shenmu County produces about 70 million tons of raw coal every year. During the screening process, lump coal accounts for 60%, about 42 million tons. The lump coal with a particle size above ￠30mm is all used by the existing 600,000 t / a Gelan Coal Plant; after screening Mixed coal accounts for 40%, about 28 million tons, all of which are used as thermal coal. In the mixed coal, ￠6-20mm crushed coal accounts for 20%, about 5.6 million tons, and it is a pity to use it as electric coal. If the 5.6 million tons of ￠6-20mm small particle coal can be used to produce semi-coke, it...
