Complexity, such as halogenated hydrocarbon, benzene series species are classified as priority pollutant by multinational, and murder by poisoning is big, accumulation property is strong, difficult to degrade.Chemical industry is useless
Salt has strong pungent smell.[ Environmental Protection Department portion enables the 39th to " the National Hazard waste register " that China 2016 promulgates
Number ], the abraum salt of a variety of Essential Chemistry pharmacy procedures and pesticide chemical production process output is clearly included in register, belong to HW02 or
HW04 classification, hazard property T.According to statistics, the abraum salt generated in the production process of national chemical product (especially pesticide) just reaches
5000000 t or more, and many enterprises produce " swell-warehouse " phenomenon, can not handle.The safety and environmental protection of chemical industry abraum salt is handled,
Development problem as chemical industry.
The processing mode of traditional chemical industry abraum salt has directly landfill, desalinization of soil by flooding or leaching method and incineration method.
With the expansion of original Chemical Manufacture scale and emerging in large numbers for new chemicals, the yield of chemical industry abraum salt also with Japanese TV play
Increase, landfill needs to occupy a large amount of places, and abraum salt is directly exposed in natural environment after landfill, and wherein harmful constituent may be by rain
Water or landfill leachate leach, and do great damage to groundwater resources and the ecosystem.
Desalinization of soil by flooding or leaching method washs abraum salt with water or solvent material, washes away the impurity in abraum salt as far as possible, and the salt of processing is used for
Join alkali industry.This method is relatively adapted to the abraum salt that impurity content is few and impurity component is single.Its shortcomings that is washing water and solvent
There are the secondary pollutions such as processing, in addition the impurity content in abraum salt is often unstable, slurry and solvent usage
It is difficult to control, impurity is difficult to clean, and scale processing is realized difficult.
Incineration method is that abraum salt is handled using rotary kiln, hot-blast stove etc., but because use the type of furnace thermal efficiency is low, organic matter decomposition
It is not thorough, the reasons such as ring formation blocking pipeline after fused salt condensation, non-large-scale promotion application.

The furnace bottom of the smelting furnace leans to one side position side equipped with discharge port, separately as a further improvement of the utility model,
Side is equipped with accident mouth.
The discharge port is connected with receipts salt bath by thermal insulation chute as a further improvement of the utility model,.
The smelting furnace is vertical cylindrical furnace as a further improvement of the utility model, and furnace roof is horizontal furnace roof.
Waste heat boiler, water cooler, cloth are connected in turn after the dual firing chamber as a further improvement of the utility model,
Bag collector, lye absorption tower, electrostatic precipitator.
Flue used in the smelting furnace and dual firing chamber is that replaceable water cooling is living as a further improvement of the utility model,
Save flue.
The utility model feature is as follows:
1, using the smelting furnace of independent development, fused salt forms high temperature molten bath in furnace, and the thermal efficiency is high, and mass-and heat-transfer is fast, has
Machine object carries out full combustion in furnace, decomposes.
2, the affiliated flue of device uses replaceable water cooling movable joint flue, can replace in time after fused salt ring formation, not influence to give birth to
It produces stable and continuous.
3, the flue gas that smelting furnace generates is introduced into dual firing chamber's second-time burning, guarantee flue gas in 1100 DEG C or more stop 2 s of >,
Organic matter thoroughly decomposes.Heat is recycled through waste heat boiler again, flue-gas temperature is down to 550 DEG C after waste heat boiler out, cooling into water
Device is chilled to dioxin 250 DEG C of temperature of regeneration hereinafter, avoiding the regeneration of dioxin.Flue gas after cooling passes through bag collection
It is emptied after device gathers dust, lye absorbs and electrostatic precipitator processing.To reinforce the removal rate to heavy metals such as dioxin and lead, when necessary
Active carbon is sprayed into flue before bagroom.By above-mentioned measure, flue gas qualified discharge ensure that.
The utility model can be realized the recycling and harmless treatment of different classes of chemical industry abraum salt, recycle in abraum salt
Nacl, treatment process high production efficiency, steady and continuous, energy conservation and environmental protection.
