Embodiment 1

[0026] In the present embodiment, industrial slag salt is processed in batch mode, and its method comprises the following steps:

[0027] A. Introduce air and natural gas into the intake pipe 3, ignite, and continue burning after the gas is evenly distributed by the distribution plate 2; the temperature of the dense phase incineration zone 10 is controlled at 500-600 °C;

[0028] B, close the discharge pipe 5, import dry industrial slag salt from the feed pipe 4, and the particle size of the industrial slag salt is not more than 600 μm;

[0029] C, the recombination in the industrial slag salt is decomposed into light components and coke, the moisture in which is evaporated, and the organic matter and coke are burned;

[0030] D. The small particle size substances in the dense-phase incineration zone 10 are blown into the dilute-phase incineration zone 11, presenting a suspended state;

[0031] E. The tail gas is discharged through the top pipeline of the incinerator 1, and t...

Embodiment 2

[0034] In the present embodiment, industrial slag salt is processed in continuous operation mode, and its method comprises the following steps:

[0035] A. Introduce air and natural gas into the intake pipe 3, ignite, and continue burning after the gas is evenly distributed by the distribution plate 2; the temperature of the dense phase incineration zone 10 is controlled at 500-600 °C;

[0036] B. Continuously import dry industrial slag salt from the feed pipe 4, and the particle size of the industrial slag salt is not more than 600 μm;

[0037] C, the recombination in the industrial slag salt is decomposed into light components and coke, the moisture in which is evaporated, and the organic matter and coke are burned;

[0038] D. The small particle size substances in the dense-phase incineration zone 10 are blown into the dilute-phase incineration zone 11, presenting a suspended state;

[0039] E. The tail gas is discharged through the top pipeline of the incinerator 1, and t...

Abstract

The invention provides an industrial slag salt bubbling fluidized bed incineration harmless treatment device. The device can be used for conducting batched harmless treatment on industrial slag salt, the purity of obtained salt particles is high, and the treatment technology is simple. The device comprises a vertically-arranged incinerator. The lower portion of the incinerator is provided with a dense-phase incineration area, and the upper portion of the incinerator is provided with a dilute-phase incineration area. The diameter of the dense-phase incineration area is smaller than that of the dilute-phase incineration area. A distribution plate is arranged at the bottom of the dense-phase incineration area, and an air inlet pipeline is connected to the distribution plate. One side of the dense-phase incineration area above the distribution plate is connected with a feeding pipe, and the other side of the dense-phase incineration area above the distribution plate is connected with a discharging pipe. An inlet of the feeding pipe is arranged above an inlet of the discharging pipe. The top of the incinerator is in pipeline connection with a single-pipe cyclone separator A which is in pipeline connection with a single-pipe cyclone separator B.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an industrial slag salt bubbling fluidized bed incineration harmless treatment device. Background technique [0002] In the process of producing hydrazine hydrate, furan phenol, pesticides, intermediates and other products, a large amount of industrial slag salt will be produced, and its components mainly include: sodium chloride 80-90%, water 2-8%, toxic organic matter 2-10% . At present, due to the lack of energy-saving and environmentally friendly treatment methods, this kind of waste is mainly disposed of by landfill, resulting in waste of resources and environmental pollution. Contents of the invention [0003] The technical problem solved by the present invention is to provide a harmless treatment device for industrial slag salt bubbling fluidized bed incineration, which can conduct batch harmless treatment of industrial slag salt, the obtained salt particles have...
