Carbonization pyrolysis oven slagging-off mechanism

Technical Field

The utility model relates to a msw incineration technical field, concretely relates to carbonization pyrolysis oven slagging-off mechanism.

Background

People always generate garbage in daily work and life, and the garbage is various in types, such as household garbage, plastic products, rubber products, dry branches and rotten leaves, driftage in river and river water and the like. At present, domestic garbage is treated mainly by centralized storage and then unified centralized landfill, and the treatment means has many disadvantages. The common treatment means is to burn the garbage, but the traditional burning mode can generate a large amount of smoke dust and has bad influence on the environment; the traditional garbage incinerator can also generate smoke, and the traditional garbage incinerator has the problems of incomplete combustion degree and unsatisfactory combustion effect; another problem is that incineration of refuse requires a long period of continuous combustion. The energy consumption is increased. At present, the design of combining the efficiency and the environmental protection of the incinerator is not available.

The conventional incinerator discharges the incinerated slag directly from a slag discharge port, and normal operation of the pyrolysis furnace is affected if slag is not uniformly removed or large slag cannot be discharged. The garbage pyrolyzing furnace is a novel garbage treatment device, can maximally realize reduction, harmlessness and recycling of garbage treatment, and conforms to the national purpose of garbage treatment. The slag produced by the pyrolysis furnace is discharged through the slag removing mechanism, the slag removing thickness is basically consistent, and the large slag is crushed, so that the normal operation of the pyrolysis furnace can be ensured, and the normal operation of the pyrolysis furnace can be influenced if the slag is not uniformly removed or the large slag cannot be discharged. Meanwhile, the pyrolysis furnace has strict requirements on the amount of air entering the furnace, and the air inlet device is generally arranged at the bottom of the pyrolysis furnace, so that the sealing performance of the deslagging mechanism must be ensured in the rotating process.

Detailed Description

FIG. 1 is the structure schematic diagram of the slag removal mechanism of the carbonization pyrolysis furnace. As shown in fig. 1, the utility model discloses a carbonization pyrolysis furnace deslagging mechanism sets up in the furnace body bottom of carbonization pyrolysis furnace, include: the grate 1, the slag breaker 2, a plurality of ash stirring wings 3, the ash supporting plate 4 and the slag discharging port 5 are sequentially arranged from top to bottom, wherein the driving device 6 drives the grate 1 to rotate, the slag is brought into the slag breaker 2, the slag breaker 2 crushes large blocks of slag, the crushed slag falls into the ash supporting plate 4, and the ash stirring wings 5 push the slag into the slag discharging port 5 to be discharged. In order to better push the slag into the slag discharge port 5, the number of the ash poking fins 3 is 3, and the ash poking fins are uniformly distributed in the circumferential direction in the furnace body; the slag falling into the ash supporting plate 3 is extruded towards the middle part to fall into the slag discharging port 5 under the action of the ash pulling fin 3 in the rotating process

The furnace grate 1 is of a tower structure, and the center point of the furnace grate 1 deviates from the center of the furnace body, namely, the furnace grate is eccentrically arranged. Further, the eccentrically arranged tower grate is beneficial to movement and slag breaking of slag, and in the eccentric condition, the gap between the grate 1 and the hearth side is changed, namely the gap is large sometimes, the gap is small sometimes, when the gap is large, more slag enters, when the gap is small, the slag is extruded, and therefore the slag breaking effect is achieved. The slag breaker 2 arranged at the lower part of the grate 1 adopts a triangular structure and has the same structure with the corresponding position of the hearth, and further, the slag breaker is composed of a plurality of triangular structures, a certain interval is formed between the triangular structures, the arrangement mode is the same with that of the corresponding position of the hearth, and the slag falling into the slag breaker can break due to the change of the gap.

In addition, the pyrolysis furnace has strict requirements on the amount of air entering the furnace, and the air inlet device is generally arranged at the bottom of the pyrolysis furnace, so that the sealing performance of the deslagging mechanism must be ensured in the rotating process. In order to reach better sealed effect, carbonization pyrolysis oven slagging-off mechanism still includes water seal groove 7, water seal groove 7 sets up along furnace body outside circumference, adds water in water seal groove 7, guarantees that the air of drum-in does not leak, and its surface of water highly depends on the wind pressure of air-blower.

To sum up, the utility model discloses a carbonization pyrolysis furnace slagging-off mechanism, simple structure can evenly discharge the slag in the stove to have the broken function of bold slag, guarantee pyrolysis furnace normal operating.
