Problems solved by technology
This kind of material is incinerated and disposed of in an incinerator. When the material is compatible, the acyl chloride volatilizes quickly at room temperature, and a large amount of irritating gas is generated in the batching space, and workers cannot perform material compatibility operations.
In addition, in order to meet the chlorine content requirements of compatible materials, only a small amount can be added
Harmful to workers' health and the treatment environment, it cannot be incinerated in large quantities

The invention discloses device and method for removing chlorine-containing substances in incineration materials through high-negative-pressure distillation. The device comprises a distillation still, a receiving tank, a cooling packaging tank, a heating circulation system, a circulating water system and a negative-pressure vacuum device, wherein a material inlet, a gas-phase material outlet and a slag outlet are formed in the upper part of the distillation still; the cooling packaging tank communicates with the slag outlet of the distillation still; the receiving tank communicates with the gas-phase material outlet of the distillation still; the heating circulation system is characterized in that heated heat conduction oil circulates in a distillation still jacket through a pipeline; the circulating water system communicates with the cooling packaging tank and a graphite condenser in a circulating manner; and the negative-pressure vacuum device communicates with a receiving tank through a vacuum pipeline. According to the device and method, an original viscous chlorine-containing material can be changed into a brittle solid material to be conveniently crushed; the chloride content in the material is removed by more than 80%; the material is free of pungent smell at normal temperature, and material compatibility operation is facilitated; and mass incineration disposal is realized.
Description
technical field [0001] The method relates to the technical field of separation of chlorine-containing organic substances in molecules of incineration materials, in particular to a device and method for removing residual chlorine-containing substances in incineration materials by high negative pressure distillation. Background technique [0002] Various compounds with high chlorine content accounted for about 45% in the residue of imidacloprid pesticide production. Acyl chlorides account for about 15%. This kind of material is incinerated and disposed of in an incinerator. When the material is compatible, the acyl chloride volatilizes quickly at room temperature, and a large amount of irritating gas is generated in the batching space, and workers cannot carry out the material compatibility operation. In addition, in order to meet the chlorine content requirements of compatible materials, only a small amount can be added. It is harmful to the workers' health and the treatmen...
