The invention discloses a 40-thousand-ton hard carbon black reaction furnace and a production process of carbon black. The carbon black reaction furnace comprises a combustion chamber, a venturi tube, a reaction chamber, and a quench zone. The uniquely designed combustion chamber of the reaction furnace ensures that the distribution of the temperature field of the carbon black production is more reasonable, the appropriate angle, length and inner diameter of the venturi tube ensure that raw oil is fully vaporized and sheared on the venturi tube part; and the reasonably designed reaction section and the matched quench zone ensure that the carbon black cracking reaction can be performed quickly, and the side reaction can be inhibited. Coal gas or natural gas is used as a fuel, the range of the raw oil is wider, the production capacity of the carbon black is high, unit consumption is low, a small amount of polluted product is discharged and the quality of the carbon black is high.

The invention discloses a microwave pulverized coal cracking and retorting furnace, which comprises a feeding hoist, a limit-sealed coal storage bunker and a limit-seal coal supply bunker, a furnace body (2) in a preheating drying section, and a ceramic plate turning machine (3). , heating section furnace body (4), pyrolysis and carbonization section furnace body (5), cooling section furnace body (6), discharge section furnace body (7), gas ascending channel (8), refractory heat preservation system (9), microwave System (10), microwave slit antenna (11), frame platform (12), semi-coke cooling system and gas water seal (13), semi-coke collection system (14), raw gas collection port (15), furnace body Microwave suppression and explosion-proof devices are installed at the joints of components. The present invention acts on the cracking and carbonization of pulverized coal based on the principle of microwave heating and non-thermal catalytic effect, so compared with the current dominant gas heat carrier carbonization process, it is suitable for a wide range of raw coal specifications, fast cracking speed, high output efficiency, good product quality, and no waste. Environmental pollution and other aspects have obvious advantages.

A continuous internal heating type double-barrel cracking furnace for solid organic matter is of a fixed horizontal double-barrel-body structure. Continuous feeding is performed on the upper portion of one end of each barrel body. Continuous slag discharging is performed on the lower portion of the other end of each barrel body. The upper portion of each barrel body is provided with a plurality of gas outlets. Two rotors are arranged in the dual barrel bodies side by side. While the rotors are used for heating materials in the barrel bodies in a dividing-wall mode, the materials are propelled and stirred rotationally. Each rotor is composed of a shaft barrel and a screw band, and each screw band is of a hollow structure. High-temperature flue gas firstly enters the shaft barrels and then enters inner cavities of the screw bands through flow guiding holes, the flue gas rotates along with the rotating barrels in the inner cavities of the screw bands and spirally flows along the inner cavities of the screw bands at the same time, heat is fully released, the materials are heated, and then the flue gas enters the shaft barrels to be exhausted. The flue gas and the materials are in countercurrent dividing-wall heat transfer, temperature difference is large, smoke exhaust temperature is low, heating is uniform, cracking gas is exhausted in time, secondary cracking is avoided, and the oil yield is high. The furnace is scientific and reasonable in structure and technology, high in machining capacity, low in cost, capable of achieving energy conservation and environment protection, safe, reliable and low in labor intensity, pollution caused by combustion of dioxin is avoided, resources are reasonably utilized, and market popularization value is great.
