Coking flue gas and ammonia-containing wastewater integrated treatment system

Abstract

The invention relates to the technical field of purification equipment, in particular to a coking flue gas and ammonia-containing wastewater integrated treatment system which comprises a sulfur removal box, a first partition plate is fixedly connected to the position, close to the upper end, of the inner surface of the sulfur removal box, and a second partition plate is fixedly connected to the position, close to the lower portion of the first partition plate, of the inner surface of the sulfur removal box. The sulfur removal box is divided into a zone A, a zone B and a zone C from top to bottom by the partition plate I and the partition plate II. According to the device structure, smoke dust in coking flue gas can be effectively cleaned, and ammonia-containing wastewater is heated by utilizing high-temperature flue gas, so that volatilization of ammonia gas in the ammonia-containing wastewater is facilitated; the device is simple in structure and convenient to operate, reaction between a magnesium compound or hydrophosphate and ammonia in the wastewater is facilitated, the ammonia removal effect is better, smoke dust mixed in the wastewater can be filtered, cleaned and collected, the filter screen can keep a good filtering effect for a long time, and meanwhile workers can conveniently collect and treat impurities such as the smoke dust.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to an integrated treatment system for coking flue gas and ammonia-containing wastewater. Background technique [0002] With the development of industry, a lot of waste gas and waste water are often produced in industrial production. For example, coking flue gas will contain a large amount of sulfur dioxide; if these substances are directly discharged into the environment, it will cause serious damage to the environment and human life. Bad influence, so before discharging these waste gas and waste water, it is necessary to carry out purification treatment to reduce the damage to the environment. There are many treatment methods for coking flue gas and ammonia-containing waste water in the existing technology, which can reduce environmental pollution. Advantages such as energy recycling; [0003] However, the traditional coking flue gas and ammonia-containing wastewate...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional coking flue gas and ammonia-containing wastewater often need to be treated separately, which greatly increases the purification cost, and the treatment is extremely troublesome, the process is complicated, and the waste of energy is increased, and the coking flue gas contains a large amount of smoke and dust. , It is extremely troublesome to clean up and requires a lot of manpower and material resources. The traditional evolutionary equipment lacks automatic dust cleaning equipment, and the overall needs to be improved
