Background technology
In " national Hazardous Waste List ", the HW11 that lists, HW12, HW13 class refuse, it mainly comprises the useless tarry residue that produces from refining, distillation and any pyrolysis processing, for example, the refuse that from the production preparation of printing ink, dyestuff, pigment, paint, lacquer, finishing varnish and use procedure, produces and the refuse that from production, preparation and the use procedure of resin, latex, plasticizer, glue/adhesive, produces etc.These refuses mainly are that the form with solid waste, liquid wastes, semi-solid paste refuse exists from the state.At present the processing mode of these hazardous wastes mainly is that to burn and bury be main.But owing to contain macromolecule compound (such as resin, tar etc.) in these a few class refuses more, stack at normal temperatures a period of time after refuse be easy to solidify, very difficult in container, separate, increased this class treatment of wastes produced difficulty.Therefore no matter be to bury, burn or other processing mode, it all is inevitable pre-treatment step that refuse is taken out in the container.
Take burning disposal as example, the incinerator that is applied at present the Waste disposal field mainly contains rotary kiln, grate furnace, fluid bed furnace and liquid by structure type and sprays stove etc.Wherein grate furnace can be used for burn larger volume solid waste, but because the problem that exists fire grate to come off and lump, generally be rarely used in the burning disposal of medical treatment and hazardous waste, be aspect the house refuse generating application more; Rotary kiln is the dangerous waste incinerator of relatively commonly using, can burn solid-state, semisolid and liquid refuse, but the rotary kiln incineration stove requires the charging optimum size to be no more than 100 * 100 * 200 (mm), and the refuse that does not meet the demands need to pass through broken preliminary treatment; Fluid bed was used as the existing long period of the equipment in the chemical industry, also be applied in recent years in the burning disposal of hazardous waste, but in order to guarantee the abundant fluidisation into the stove refuse, still comparatively strict to the size that enters the stove refuse, need to screen refuse, the pre-treatment step such as pulverizing, make refuse size, shape homogenization; Liquid sprays incinerator can effectively process various pumping refuses, and never incendive refuse (such as water) to the refuse that all is organic compound, is modal liquid waste incinerator.This shows no matter use above-mentioned which kind of incinerator, all is conditional to the size shape of refuse.The inventor finds when many dangerous waste incinerations processing units are carried out on-the-spot investigation, be solidificated in refuse in the container for this class, if the container of splendid attire can burn, and small volume, can put into and burn furnace chamber inside, container and refuse will carry out burning disposal together so.If metal-made container and volume are larger, for example the storing dangerous refuse 200L iron sheet container of normal use so just can only take out refuse first in the iron sheet container, then pulverize or liquefaction after carry out again burning disposal.Because this class refuse is very hard after curing, be difficult to separate with the iron sheet container, generally can only adopt the mode of manual breakage iron container that refuse is taken out.The corrosivity that hazardous waste has, volatility, toxicity and inflammable and explosive property have increased artificial working strength greatly with dangerous.
