The energy-saving and emission-reduction synergist for coal has a good desulfurization effect and a stable desulfurization product, and largely reduces pollutant emission.
Description
Technical field
The invention belongs to coal additive technical field, be specifically related to a kind of fire coal energy-saving emission-reducing synergistic agent.
Background technology
Coal resources occupy an important position in Chinese society Economic development, but continually developing and utilizing along with coal resources, and many new problems progressively highlight.Coal resources are Nonrenewable resources, and this just means that the exploitation along with coal is excavated, and coal resources also can reduce day by day.And on the other hand, because the utilization ratio of fire coal is relatively low, discharge pollutants, welding.Therefore, how to improve coal-fired utilization ratio, realizing energy-saving and emission-reduction is global problems, is also the topic that the whole world is paid close attention to jointly.In recent years, the problems such as in China's rapid development of economy process, Coal Energy Source utilization ratio is low, serious environment pollution became increasingly conspicuous, and the aggravation of contradictions of the deterioration of the ecological environment and Economic development, constrains China's sustain economic rapid and healthy to a great extent.
The interpolation of synergistic agent makes utilization ratio coal-fired at present be improved, and existing fire coal synergist majority adopts limestone desulfurization, but fire coal is in high-temp combustion, and desulfurization efficiency is low, and sulfur retention products easily decomposes, and effect is not very good.
Summary of the invention
The object of the invention is, in order to solve prior art Problems existing, to provide a kind of captured sulfur result good, the fire coal energy-saving emission-reducing synergistic agent that sulfur retention products is stable.

The present invention also provides a kind of preparation method of fire coal energy-saving emission-reducing synergistic agent, comprises the following steps:
S1: the raw material taking following weight part respectively: yttrium oxide 6-8 part, Manganse Dioxide 8-10 part, ferrous oxide 10-15 part, iron protoxide 10-15 part, sodium carbonate 3-5 part, saltpetre 3-5 part, sulfonated lignin 2-6 part, bicarbonate of ammonia 4-10 part, salt of wormwood 5-10 part, urea 6-10 part, gac 3-5 part, diatomite 2-8 part, activated alumina 2-3 part;
S2: yttrium oxide, Manganse Dioxide, ferrous oxide, iron protoxide, sodium carbonate, saltpetre are mixed, then add after sulfonated lignin and bicarbonate of ammonia mixes 20 minutes, add salt of wormwood, urea, gac, diatomite, activated alumina again, after mixing, grinding and processing is to 90-100 order, metering packing, obtains fire coal energy-saving emission-reducing synergistic agent.
During use, add synergistic agent of the present invention according to the 0.8-1.2% of Coal-fired capacity, also can add appropriate water in synergistic agent, be prepared into liquor and add to again in fire coal.
The invention has the beneficial effects as follows:
1. fire coal energy-saving emission-reducing synergistic agent of the present invention is in use when desulfurization reaction, the volume parts of oxygen can be reduced, improve the volume parts of carbonic acid gas simultaneously, effectively inhibit the decomposition of calcium sulfate, improve the high-temperature stability of calcium sulfate, substantially increase captured sulfur result, sulfur-fixing rate is more than 90%.
2. fire coal energy-saving emission-reducing synergistic agent of the present invention is under the effect of solid sulphur auxiliary agent, effectively can improve the microtexture of synergistic agent, promote desulfurization reaction, make reaction more fully, completely, realize energy-saving and emission-reduction, and the burning situation of hypoxemia also substantially increases denitration rate, the discharge of further decreasing pollution thing, NOx, SO2 quantity discharged reduces more than 80%.
3. fire coal energy-saving emission-reducing synergistic agent of the present invention is under the effect of properties-correcting agent, and changing the coal-fired proterties when burning, improving temperature of combustion, thus improve coal-fired utilization ratio, coal combustion thermo-efficiency is more than 85%.
