“…Given the strong inhibitory effect of high concentration of alkali and alkali metal salts on microorganisms, incineration is currently the mainstream technology approach, which has absorbed a number of in-depth studies by many researchers at home and abroad. For example, the combustion tests have been conducted on an industrial scale waste liquid incinerator and a pilot scale waste liquid incinerator respectively by researchers (Kaul et al 1998, Ehrhardt et al 1998. It is concluded that the combustion temperature of 850~950 ℃ can induce the removal rate of toxic and harmful substances in the concentrated waste liquid to reach more than 99%, and the emission values of various pollutants reduced to lower than the relevant emission standards; In a work (Li et al 2007) organic waste liquid fuel has been found with the characteristics of high ignition point and low calorific value.…”

High-salinity organic waste liquid is one of the important industrial pollution sources and the main by-product of petrochemical enterprises in China. Incineration is the mainstream technology for treating this kind of waste liquid. A three-dimensional numerical simulation of a practical 18t/h waste liquid incinerator was carried out using Fluent. The velocity, temperature, component concentration and particle trajectory distribution in the incinerator were obtained, proposing a corresponding incinerator performance optimization scheme according to the simulation results. The results demonstrate that the numerical combustion model established in this paper can accurately simulate the distribution of flow, combustion and heat transfer in the incinerator, verifying the reliability of the numerical model; The overall temperature and flow field organization of this type of waste liquid incinerator is relatively reasonable, with heat exchange reported only in the flue corner and some heat exchange surfaces. The flow field and temperature field distribution in the incinerator can be effectively modified so as to improve the boiler operation and maintenance cycle by optimizing the corner flow line and furnace structure.

At present, the treatment of landfill leachate is an unavoidable challenge facing environmental problems. Incineration is one of the effective methods to treat landfill leachate which meets the 3T+E principle and can avoid the production of dioxin in the process of treatment. Based on the 3T+E principle, this paper studied the influence of burner arrangement on the treatment of landfill leachate through the numerical simulation method. The research showed that the symmetrical arrangement of reverse swirl and same direction flow were more conducive to the combustion of landfill leachate concentrations in the incinerator so that the residence time of the flue gas in the second combustion chamber can also exceed 2 s. When the nozzle arrangement height is 0.9 m–0.8 m, the wall collision rate of concentrated liquid droplets can be reduced, and the burnout rate of landfill leachate was the highest, reaching more than 92%.
