Filtering, blowing and sweeping control device for waste emulsion treatment system

Abstract

The invention discloses a filtering, blowing and sweeping control device for a waste emulsion treatment system. An emulsion filter is blown and swept by steam in a pulverized coal boiler, a blowing and sweeping device comprises a control box and a heat tracing system, an emulsion differential pressure detection branch and a steam blowing and sweeping branch are arranged in the control box, a controller is arranged in the control box and comprises a processor, a memorizer and procedures, the procedures are stored in the memorizer and can execute actions of blowing and sweeping switches of the emulsion differential pressure detection branch and the steam blowing and sweeping branch on the processor, and the heat tracing system comprises a plurality of heaters wound by copper pipes. The blowing and sweeping control device can blow and sweep the filter, pipelines and valves in the pipelines in the emulsion treatment system, so that the filter and even the whole emulsion treatment system cannot be blocked, cleaner emulsion is provided for the emulsion treatment system, so that the emulsion can be effectively combusted and utilized, and environmental protection effects can further be optimized.

Description

technical field [0001] The invention relates to energy saving and environmental protection technology, more particularly to a filtering and purging control device of a waste emulsion treatment system, which can carry out purging control of filters in a waste emulsion treatment system based on a pulverized coal boiler of a power plant. Background technique [0002] Emulsion is widely used in grinding, electromechanical, machining, metallurgy, forging and other metal processing processes. Waste oil), its main components are water, mechanical impurities, base oil (mineral oil, vegetable oil and synthetic oil), fatty acid, surfactant, anti-corrosion agent and various additives. In industrial production, with the recycling of the emulsion, the alternation of cold and heat and microbial degradation will lead to its deterioration, making it lose its original characteristics and effectiveness, so it needs to be replaced periodically, which will continuously generate more waste emuls...

AI Technical Summary

Problems solved by technology

This treatment method has low waste gas utilization efficiency and low combustion efficiency. Generally speaking, the combustion efficiency of the waste emulsion in the kiln is only about 45%, and there are high requirements for the combustible content (ie, calorific value) of waste oil. Otherwise, it cannot be burned, and the waste gas generated during the disposal process is difficult to recycle, and it also produces a large amount of harmful waste gas.

Although this treatment method has improved compared with the above-mentioned treatment method, it can achieve the purpose of consuming and disposing of the waste emulsion, but due to the short combustion process and low efficiency in the kiln, the heat energy of the waste emulsion cannot be fully utilized, and it will also cause damage to the furnace wall. And flue contamination and air pollution, can not use renewable energy, it is impossible and can not be popularized
