Technical Field

The utility model relates to a pyrolysis equipment technical field specifically is a heating all sets up the dry pyrolysis device in reation kettle one end with the feeding.

Background

Currently, the rapid development of society has caused mankind to generate excessive waste organic sludge, which causes not only environmental pollution, such as domestic sludge, industrial sludge, etc., and thus, for environmental protection, people have begun to design environmental protection equipment capable of drying the waste organic sludge.

The drying reaction kettle of the existing drying and pyrolysis equipment is usually a double reaction kettle or a single reaction kettle, the two ends of the reaction kettle are respectively provided with a burner and a feeder, the burner is far away from the feeder, when the sludge to be dried is conveyed to one end of the reaction kettle close to the burner from the feeder, the continuously overturned sludge can gradually become dry along with the rise of the temperature in the reaction kettle, therefore, when the sludge is conveyed to one end of the burner, the dried sludge can easily cause burning or be burnt at the moment, the burnt smell after the partial drying sludge is burnt can be discharged outwards along with the smoke holes arranged on the reaction kettle to cause environmental pollution

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a heating all sets up the dry pyrolysis device in reation kettle one end with the feeding to solve the problem that provides in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a drying pyrolysis device with heating and feeding arranged at one end of a reaction kettle comprises an external rotation type reaction kettle, an inner reaction kettle which rotates along with the external rotation type reaction kettle is arranged in the external rotation type reaction kettle, a combustion furnace and a heating chamber which are provided with a burner are arranged at the same end of a feeder, and the heating chamber is arranged at one end of the external rotation type reaction kettle; a combustion furnace provided with a burner is arranged at the outer end of the heating chamber; the feeder extends into the inner reaction kettle after extending into the heating chamber.

Preferably, the sludge is pushed into the inner reaction kettle under the pushing of the feeder, and the pushing direction of the sludge in the inner reaction kettle is opposite to that in the outer rotary reaction kettle.

Preferably, a certain number of energy balls are arranged in the external rotation type reaction kettle, and a material raising plate is arranged at one end, close to the heating chamber, of the inner wall of the external rotation type reaction kettle.

Preferably, one end of the outward-rotating reaction kettle, which is close to the material lifting plate, is respectively provided with a slag outlet and an air outlet.

Preferably, a screening port is further arranged above the slag outlet.

Compared with the prior art, the beneficial effects of the utility model are that: the burner, the heating chamber and the feeder are all arranged at the same end of the reaction kettle, the heating chamber enables heat generated by the burner to continuously enter the inner reaction kettle, the water content ratio of the feeder to sludge to be dried entering the inner reaction kettle is higher, and the burner can not burn the sludge when heating the sludge; when the sludge runs towards the other end of the internal reaction kettle, although the sludge is continuously dried, the temperature is continuously reduced because the combustor is arranged at the feeding end, the requirement of water evaporation can only be met, coking or combustion cannot be caused, and therefore the generation of peculiar smell caused by the fact that the sludge is burnt due to overhigh temperature is prevented. The sludge in the inner reaction kettle of the inner reaction kettle is transferred to the outer rotary reaction kettle at the tail part and then is continuously and fully dried in the conveying process of the outer rotary reaction kettle, and the heat generated by the combustion of the combustor is fully utilized.
