Abstract

The invention discloses a device and a method for producing ADC by a chorine oxidation method. The device comprises a water-washing tower, a cooler, a water mist separator and a chlorine inlet reactor which are connected with one another sequentially; the chlorine inlet reactor comprises a reaction kettle, a circulating pipeline, a circulating pump and an ejector or a Venturi tube; a liquid inlet of the ejector or the Venturi tube is connected with one end of the circulating pipeline; the other end of the circulating pipeline is connected with a discharging opening of the reaction kettle; a liquid outlet of the ejector or the Venturi tube is connected with a feeding opening of the reaction kettle; a suction opening of the ejector or the Venturi tube is communicated with a chloride discharge pipe of the water mist separator; and the circulating pump is arranged on the circulating pipeline. The device and the method for producing the ADC by the chorine oxidation method has the following advantages: a sulfuric acid drying tower is not used and a large amount of waste sulfuric acid is not generated; a chlorine compressor is not used, so the investment cost is reduced and the risk of high-pressure chlorine leakage is avoided; a high-pressure chlorine pipeline is not needed, so a large amount of leakage accidents are reduced; and the economic benefit is high, and safety and environmental friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a device and method for producing ADC by chlorine oxidation. Background technique [0002] When producing ADC by chlorine gas oxidation, the existing process is usually: chlorine gas cooling→drying tower (with sulfuric acid)→bubble cap drying tower→acid mist trap→chlorine compressor, after which high-pressure chlorine gas is used directly or liquefied by chlorine gas Regasification for use. The disadvantages of the existing method are: a large amount of waste sulfuric acid will be produced; equipment investment is high; and there is a hidden danger of leakage accidents in the high-pressure chlorine gas pipeline. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a device and method for producing ADC by chlorine oxidation. [0004] The invention provides a device for producing ADC by chlorine oxidation, w...
