Salty waste water incineration disposal system and disposal method thereof

Abstract

The invention discloses a salty waste water incineration disposal system and a disposal method of the salty waste water incineration disposal system and relates to the field of salty waste water incineration disposal. According to the technical scheme, an existing method that a large amount of water is used for cooling waste water rapidly is changed, heat exchange is conducted through a radiation radiator, therefore, the temperature of smoke is effectively lowered, high-temperature smoke is provided through a coal burning machine, and the problem that burning cost of natural gas is high is solved. Furthermore, circulating smoke pipelines are arranged in a plurality of places of the whole system, therefore, heat energy is recovered, and the temperature of the smoke is effectively controlled in a suitable range, for instance, the state of salt in the salty waste water is prevented from becoming a molten state, and the temperature of the salty waste water entering a multi-pipe dust remover and the temperature of the salty waste water entering a Tai Mian high-temperature dust remover are controlled within 600 DEG C to 650 DEG C. Dust removing efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of saline wastewater incineration treatment, in particular to a saline wastewater incineration treatment system capable of efficiently recovering organic salts and a treatment method thereof. Background technique [0002] At present, it is inevitable to produce a large amount of high-salt wastewater in industrial production. The traditional process generally adopts the method of incinerating high-salt wastewater. The existing problems are: 1. The saline wastewater must be cooled by rapid cooling after incineration. The traditional method is to use a large amount of water for mixing and cooling, and the quenched water needs to be discharged to the sewage treatment plant for subsequent treatment, which greatly wastes water resources and the subsequent treatment process is complicated, and the investment cost is high; 2. During the incineration process, If the incineration temperature is too high, the salt will melt, and...

AI Technical Summary

Problems solved by technology

[0005] The technical key of the present invention is to change the previous method of quenching with a large amount of water, use a radiation radiator for heat exchange, effectively reduce the flue gas temperature, and provide high-temperature flue gas through a coal-burning machine, overcome the problem of high cost of burning natural gas, and then Or install multiple circulating flue gas pipes in the whole system to effectively control the flue gas at an appropriate temperature while recovering heat energy, for example: to prevent the salt in the saline wastewater from becoming molten; to enter the multi-tube dust collector and too cotton The temperature of the high-temperature dust collector is controlled at 600 ° C ~ 650 ° C, etc.
