High concentration saliferous organic waste liquor recycling chemical intermediate and waste heat utilizing boiler system

Abstract

The invention discloses a high concentration saliferous organic waste liquor recycling chemical intermediate and waste heat utilizing boiler system which comprises an incineration boiler, a first-level dust collecting device, a secondary combustion device, a waste heat boiler and a second-level dust collecting device. An exhaust gas outlet of the incineration boiler is communicated with the first-level dust collecting device through a pipeline, an outlet of the first-level dust collecting device is communicated with the secondary combustion device through a pipeline, an outlet of the secondary combustion device is connected with the waste heat boiler through a pipeline, an outlet of the waste heat coiler is connected with the second-level dust collecting device through a pipeline, and exhaust gas of the second-level dust collecting device is introduced in a chimney through a draught fan and is exhausted. According to the high concentration saliferous organic waste liquor recycling chemical intermediate and waste heat utilizing boiler system, a combustion mode combining layer combustion and chamber combustion is adopted, spray mist drying, dry distillation, evaporation and combination reaction are carried out in a primary combustion chamber, the spray mist drying technology is adopted, the treatment mode of single incineration waste disposal and a centralized waste disposal mode are broken through, the simultaneous efficient multi-time incineration disposal of liquid, gas and solid diversified waste is achieved, and precious chemical intermediate raw materials are further generated.

Description

Technical field [0001] The invention relates to a chemical intermediate for recycling high-concentration salt-containing organic waste liquid in chemical, pesticide, oil refining, printing and dyeing, papermaking and other industries for harmless, reduction and resource treatment. Waste heat utilization boiler system. Background technique [0002] Nowadays, in the production process of chemical, pesticide, oil refining, printing and dyeing, papermaking and other industries, there are often some high-risk waste gas and high-salt (mainly alkali metal salts) organic waste liquids. In order to avoid these high-risk pollutants from harming human health It poses a threat to the natural environment and needs to be harmless, reduced, and recycled. Due to the high salt content and high toxicity of these wastes, they can hardly be biochemically treated. Therefore, a reasonable and effective incineration treatment technology has been found to reduce the pollution of the waste to the enviro...

Problems solved by technology

In the traditional incineration treatment system, the incinerator has a single combustion method and can only simply process a single waste

Especially in the incineration treatment of high-concentration salt-containing organic waste liquid, the temperature control in the traditional incinerator is only to ensure full combustion, and the high temperature is used to completely incinerate organic and harmful components to ensure environmental protection and discharge.

For high-concentration salt-containing organic waste liquid containing a large number of useful components that can be used as chemical raw materials, under certain conditions, it can use the control of incineration temperature to generate certain reaction products, which can be used as intermediates such as chemical raw materials. Turning waste into treasure, but this kind of problem has always been difficult to solve
