Problems solved by technology

[0004] Aiming at the two disadvantages of the above-mentioned treatment method, which will produce new organic pollutants and be unsuitable for industrial waste salt with high organic content, the present invention provides a device for efficiently treating industrial waste salt, specifically providing a high-efficiency industrial waste salt The melting and incineration device can carbonize industrial waste salt at high temperature, so that the industrial waste salt can reach a molten state and remove most of the organic matter. At the same time, the equipment uses high-temperature flue gas to preheat the combustion-supporting air to improve the combustion conditions. Decomposition, thereby solving the problem of high organic matter treatment, and improving the thermal efficiency of the furnace

Abstract

The invention belongs to the technical field of environmental protection and industrial waste treatment and particularly relates to a high-efficiency melting and incineration device for industrial waste salt. The high-efficiency melting and incineration device for industrial waste salt comprises a melting incinerator body, a waste heat recovery device, a burner A, a burner B, a combustion air pipeline A, a combustion air pipeline B, a flue gas pipeline, a blower, an induced draft fan, an electric control valve, a lifting feeder, a furnace bottom transmission mechanism and a transmission discharging device. According to the high-efficiency melting and incineration device for industrial waste salt, toxic organic compounds in secondary high-temperature incineration flue gas are utilized, andthe waste heat recovery device is utilized, so that the flue gas temperature is reduced, combustion-supporting air is preheated, and meanwhile the effects of protecting the environment and improving the thermal efficiency of a furnace can be achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and industrial waste treatment, and in particular relates to a high-efficiency melting and incineration device for industrial waste salt. Background technique [0002] In recent years, my country's petrochemical, pharmaceutical, pesticide and refined production industries have developed rapidly, and the production scale has rapidly increased. At the same time, the scale of accompanying waste has also become larger. Among them, industrial waste salt solution is the most toxic and harmful polluting waste in these industries. thing. Because when these industries purify and treat products, they will carry out acidification and alkalization to form a large amount of NaCl solution, also known as waste salt solution, and mixed with a wide variety of organic compounds, the content of which accounts for 5-10% of the total. Reducing the amount of waste liquid will dry-steam these waste salt...
