Abstract

The invention discloses a waste emulsion treatment system utilizing a power plant boiler. The system is connected with a boiler furnace and comprises a pretreatment device for removing impurities in waste emulsion; a storage subsystem arranged at a subsequent station of the pretreatment device and used for loading, unloading, storing and heating the waste emulsion; a continuous filtering device communicated with the storage subsystem through a conveying pipeline and used for filtering the waste emulsion; a combustor and control equipment which are communicated with the continuous filtering device through a conveying subsystem, and the combustor and the control equipment are further communicated with the boiler furnace and used for fully combusting the emulsified liquid heated by the storage subsystem in the boiler furnace; and an odor collection and treatment subsystem which is used for collecting and removing odor generated during operation of the waste emulsion treatment system. According to the system, various active ingredients in the emulsion can be thoroughly decomposed, and the heat value in the emulsion is utilized for power generation.

Description

technical field [0001] The invention relates to waste emulsion treatment technology, more specifically, relates to a waste emulsion treatment system using power plant boilers. Background technique [0002] Emulsions are widely used in metal processing such as grinding, electromechanical, machining, metallurgy, forging, etc., to lubricate, cool, surface clean and prevent corrosion. It will cause it to deteriorate and lose its original characteristics and effectiveness, so it needs to be replaced periodically, which will continuously produce more waste emulsions, the main components of which are water, mechanical impurities, base oils (mineral oils, vegetable oils and synthetics) Oil), fatty acids, surfactants, anti-corrosion agents and various additives, etc. [0003] Due to the large number of surfactants and organic additives in the waste emulsion, the COD and BOD values ​​of the waste emulsion are seriously exceeded. If not disposed of properly, it will seriously endanger...
