Deep purification equipment for dangerous waste incineration flue gas and purification treatment method of deep purification equipment

Abstract

The invention puts forward deep purification equipment for dangerous waste incineration flue gas. The deep purification equipment comprises a rotary kiln, a boiler, a quenching tower, a spraying tower, a composite dust remover, a first flue gas heat exchanger, a reactor, a deacidification tower, a dust remover and a chimney; the rotary kiln, the boiler, the quenching tower, the spraying tower, thecomposite dust remover, the first flue gas heat exchanger, the deacidification tower, the dust remover and the chimney are sequentially connected through pipelines; the reactor is connected onto thefirst flue gas heat exchanger; a water sprayer is arranged on the boiler; an atomizer is arranged on the spraying tower; and a powder sprayer is arranged on the composite dust remover. Heat exchange is performed on the flue gas, denitration of the glue gas is realized, nitric oxide in the flue gas is removed, activated carbon powder is sprayed into the composite dust remover, dioxin in the flue gas can be removed, baking soda powder is sprayed by the powder sprayer, and acid gas in the flue gas can be removed by the aid of the deacidification tower, so that ultra-clean emission of the organicdangerous waste incineration flue gas can be realized.

Description

【Technical field】 [0001] The invention relates to the technical field of incineration flue gas purification equipment, in particular to a deep purification equipment for hazardous waste incineration flue gas and a purification treatment method thereof. 【Background technique】 [0002] At present, the purification system for flue gas pollution from organic hazardous waste incineration is mainly composed of flue gas quenching, activated carbon injection, bag dust removal, dry / semi-dry and wet deacidification, forming a preliminary organic hazardous waste incineration flue gas Air purification system. However, in the actual flue gas control process of organic hazardous waste incineration, there are still problems such as poor operation stability of flue gas purification facilities, difficulty in meeting the standards for stable and continuous operation, and lack of deep purification technology and equipment. In addition, there are many types of organic hazardous waste, which ne...

Problems solved by technology

However, in the actual flue gas control process of organic hazardous waste incineration, there are still problems such as poor operation stability of flue gas purification facilities, difficulty in reaching the standard for stable and continuous operation, and lack of deep purification technology and equipment.

In addition, there are many types of organic hazardous waste, which need to be incinerated after compatibility. The composition of organic hazardous waste fluctuates greatly, and the operating load of the incinerator is unstable, resulting in relatively complex and unstable components of the flue gas produced by incineration, which also leads to failure to achieve organic waste. Ultra-low emission standards for hazardous waste incineration flue gas
