Embodiment Construction

[0010] The low-flash point organic solvent referred to in the present invention refers to an organic solvent with a flash point lower than 28° C., and the high-concentration organic waste liquid refers to COD above 2000 mg / L, and the ratio of BOD to COD is less than 0.3.

[0011] Analyze the main components of low-flash point organic solvents and high-concentration organic waste liquids to determine whether they are mutually soluble, and choose mutually soluble organic solvents and high-concentration organic waste liquids to mix evenly without stratification. Mixing can be carried out at a ratio of 1:1 first, and then a combustion test is carried out under open flame conditions to observe whether there is a flame. According to the situation of the flame, adjust the ratio of the mixed liquid so that the mixed liquid can just burn.

[0012] Then test the calorific value of the mixed solution. If the calorific value is greater than 5000Kcal / kg, adjust the ratio of the organic solv...

Abstract

The invention discloses a low-flash-point organic solvent and high-concentration organic waste liquid mixed treatment method. The low-flash-point organic solvent and high-concentration organic waste liquid mixed treatment method comprises following steps that firstly, a low-flash-point organic solvent and high-concentration organic waste liquid which can be mutually dissolved are mixed evenly, theproportion of the mixed liquid can be controlled, the mixed liquid is combusted, the heat value is smaller than 5000 Kcal / k, and the flash point is larger than 28 DEG C; secondly, the mixed liquid isled into a secondary combustion chamber to be subject to jet firing; thirdly, waste gas obtained after combustion is subject to tail gas purification treatment and then is discharged; after the solvent and the waste liquid are mixed, the flash point of the mixed liquid obviously rises compared with the organic solvent, safe storage and transportation and incineration are achieved, after mixing,the high-concentration organic waste liquid is directly subject to jet firing and incineration treatment through the secondary combustion chamber, treatment through the conventional water treatment manner is avoided, and resource comprehensive treatment utilization of the waste is achieved.

Description

technical field [0001] The invention relates to the technical field of hazardous waste incineration, and specifically designs a method for mixing and treating low-flash point organic solvents and high-concentration organic waste liquids. Background technique [0002] (1) Low-flash point organic solvents refer to organic solvents with a flash point lower than 28°C. According to GB50016-2014 "Code for Fire Protection Design of Buildings" <Table 3.1.3 of Factory Buildings and Warehouses>, it is classified as Class A liquid. If it is not properly protected, it will easily cause personal injury and death and property damage during transportation, loading and unloading, and storage. Due to its low flash point, it is easy to cause explosion when it is disposed in an incinerator, and there is a great potential safety hazard. [0003] (2) High-concentration organic waste liquid mainly has the following characteristics: First, the concentration of organic matter is high. COD is g...
