Technical Field

The invention relates to the technical field of inorganic matter carbonization such as polluted salt, in particular to a countercurrent internal heat rotary type continuous pyrolysis polluted salt regeneration carbonization furnace.

Background

The existing inorganic substance carbonization equipment for polluted salt and the like generally has the problems of low yield, high energy consumption, incapability of continuous pyrolysis and carbonization, poor quality of carbonized carbon and the like, and has larger difference of the quality of the carbon of different batches.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the countercurrent internal heat rotary type continuous pyrolysis waste salt regeneration carbonization furnace which can be used for continuous pyrolysis and carbonization, has low energy consumption, can be produced in batch and has high carbon yield quality.

The invention solves the problem of high energy consumption in the pyrolysis carbonization process of the traditional polluted salt regeneration carbonization furnace, has no secondary pollution, improves the continuity and the economical efficiency of equipment, changes waste into valuable, and contributes to environmental greening and resource regeneration.

The technical scheme adopted by the invention is as follows: a reverse-flow internal-heat rotary type continuous pyrolysis waste salt regeneration carbonization furnace comprises: the device comprises a feeding device, a hot blast stove, a carbonization furnace body and a tail gas treatment device; the carbonization furnace body is provided with a continuous feed inlet and a discharge outlet, the discharge outlet is connected with a hot blast furnace, high-temperature gas in the hot blast furnace enters from the upper part of the discharge outlet of the carbonization furnace body, and pyrolysis flue gas enters into a tail gas treatment device from the upper part of the feed inlet; the tail part of the carbonization furnace body is provided with a discharging device, and the carbonized polluted salt is discharged from the tail part of the carbonization furnace body.

Further, feed arrangement is screw conveyer, reaches the requirement of self sealss and stable pay-off when feeding through continuous feeding mode.

Furthermore, the inside of the furnace body of the carbonization furnace is provided with the flow deflector, so that when the furnace body rotates, the materials are driven to rotate and advance, and the polluted salt is subjected to accelerated pyrolysis and carbonization.
