System and method for incineration treatment of saliferous waste residue, saliferous waste water and stink waste gas

Abstract

The invention discloses a system and a method for incineration treatment of saliferous waste residue, saliferous waste water and stink waste gas and relates to the technical field of unharmful resourceful treatment of industrial three wastes. The system and the method aim at resolving the problem that the existing three water treatment method is large in device investment, high in treatment cost, salt cannot be separated to obtain purified salt, and no device can be used for treating the three wastes simultaneously. The system for treatment comprises a pretreating chamber, a incineration device, a waste heat recycling device and a tail gas purifying device which are sequentially connected. The upper portion of the pretreating chamber is connected with a waste liquid injection port, the lower portion of the pretreating chamber is connected with a waste slag input port, and a salt discharge port is arranged at the bottom end of the pretreating chamber. The incineration device comprises a main combustion chamber and a post-combustion chamber which are sequentially connected in the smoke flowing direction. The method for treatment includes a. pretreating: delivering waste liquid, high temperature smoke and waste residue into the pretreating chamber to be combusted; b. high temperature incineration: placing the gasified waste liquid and the stink waste gas into the incineration device to be incinerated; c. waste heat recycling; and d. tail gas purification. The system and the method are especially suitable for treatment of industrial three wastes.

Description

technical field [0001] The invention relates to the technical field of harmless and resourceful treatment of three industrial wastes, in particular to an incineration treatment system and method for salty waste residue, salty waste water and malodorous waste gas. Background technique [0002] With the development of industry, the "waste water, waste residue, and waste gas" discharged by industrial production are increasing day by day. If the "three industrial wastes" fail to meet the specified discharge standards, they will be discharged into the environment, and the pollutants will undergo physical and chemical changes in the environment. Later, new substances are produced, causing environmental pollution of air, water and soil, and endangering human health. Therefore, the treatment and utilization of "three industrial wastes" will have a huge impact on the survival and development of the entire human being. [0003] In the prior art, waste residue and waste liquid are tre...

Problems solved by technology

[0006] The existing industrial wastes are treated separately, the equipment investment is large and the treatment cost is high. In the incineration method, the molten salt is mixed with the slag, and net salt cannot be obtained; and there is no prior art that can sim...
