Large-scale hot clean stove system

Technical Field

Background

In chemical manufacturing industry, an iron bucket is generally used for containing organic polymers such as resin; the residual materials in the iron drum contain a large amount of organic matters, nitrogen, sulfur, phosphorus and halogen elements, have the characteristics of high viscosity, corrosivity, acute toxicity, leaching toxicity, flammability or explosiveness and the like, belong to hazardous wastes, and easily cause short-term or long-term harmful influence on biological groups and ecological environment. However, if the residues in the iron barrel are separated, the iron barrel can be reused; however, the residue in the barrel is difficult to be completely separated from the iron barrel by a physical cleaning method due to high viscosity and difficult solubility, and corresponding waste water is generated to cause secondary pollution.

At present, the means for treating the dangerous wastes mainly comprises crushing, burning, cleaning and recycling and a hot furnace cleaning process. The direct crushing process has the disadvantages that dangerous and dangerous wastes still remain in the crushed materials, and deflagration and even explosion are easy to occur in the crushing process due to the inflammable and explosive properties of the residues; meanwhile, the iron drum can be harmless after being crushed and burned, but the utilization value is reduced; the cleaning and recycling process has the following disadvantages: due to the high viscosity of residues in the barrel, the residues can not be completely dissolved by effective solvents in a short time, the residues still remain in the barrel, and the generated wastewater forms secondary pollution; the method has the advantages that the residue in the iron bucket is gasified through the high-temperature pyrolysis process without crushing the pyrolysis incineration process, and the residual part of carbon residue is left; the carbon residue is easy to separate from the iron bucket, and the iron bucket can be recycled after discharging. During specific operation, the complete iron bucket containing dangerous waste is placed on the skip car and is conveyed to the furnace for treatment through the skip car, and after the dangerous waste is treated, the iron bucket is conveyed out through the skip car.

In view of the above-mentioned related technologies, the inventors believe that in the prior art, because the interior of the thermal cleaning furnace is a high-temperature chamber, the materials cannot be continuously fed and discharged, so that the thermal energy utilization rate of the thermal cleaning furnace is reduced; simultaneously, skip and the iron drum temperature after handling are higher, and the staff unloads the iron drum from carrying the thing car this moment, is scalded easily, has the potential safety hazard.
