Abstract

The invention belongs to the technical field of organic waste liquor and specifically relates to a method for incinerating iodine-containing organic waste liquor, purifying and treating tail gas and a system thereof. The purpose of the invention is to disclose a method for harmlessly treating organic waste liquor and a system thereof, in order to reach the national emission standard. The technical solution of the invention is that the system for incinerating iodine-containing organic waste liquor, purifying and treating tail gas comprises a waste liquor incinerating system, an flue gas cooling system, a tail gas purifying system and a tail gas emission system, wherein the flue gas cooling system is arranged on the lower part of the waste liquor incinerating system and connected with the tail gas purifying system through an flue gas pipeline; the tail gas purifying system is connected with the tail gas emission system through the flue gas pipeline. The method and the system have the beneficial effects that efficiency is high, energy is saved, circulation solution evaporation is adopted to absorb heat so that the flue gas can be quickly cooled, and quenching spray liquor is recycled to save resources and energy in maximum. According to the tail gas purifying system, iodine from combustion flue gas is recycled so that the tail gas is environmentally friendly and emitted on standard.

Description

technical field

[0001] The invention belongs to the technical field of organic waste liquid treatment, and in particular relates to an iodine-containing organic waste liquid incineration and tail gas purification treatment method and system. Background technique

[0002] The so-called iodine-containing organic waste liquid refers to organic waste water containing iodine compounds or iodine ions produced in the chemical production process. This type of waste liquid is characterized by high calorific value, high chemical oxygen demand, and high toxicity. If discharged directly without treatment, this kind of waste liquid will cause great harm to the environment.

[0003] Conventional physical, chemical, biochemical or oxidation methods are not suitable for this type of waste liquid. The effect of biochemical treatment on this kind of waste liquid is not ideal. Most of the iodine-containing waste liquid has strong toxicity, which will pose a threat to the growth and even surv...
