Description
Technical field
The present invention relates to a kind of energy saver of volatile organic matter crematory system of nitrogenous and/or sulfur-bearing.
Background technology
Life and produce in the organic solvent of extensive use, volatile one-tenth gas at room temperature, therefore have another name called volatile organic matter (Volatile Organic Compounds, VOCs), and most VOCs has certain toxicity to human body, must be processed; Separately, by air quality monitoring materials, shown, the ozone that the foul smell such as VOCs and Nox precursor and light reaction produce, having and replace the phenomenon that suspended particulates become the major pollutants that affect air pollution index (PSI), is to be one of current prevention and cure of air pollution emphasis therefore strengthen control VOCs discharge; Yet, it is a kind of of VOCs exhaust-gas treatment mode that use incinerator incinerates, VOCs clearance under proper condition can reach more than 99%, product after burning is generally water, carbon dioxide, nitrogen oxide, oxysulfide etc., therefore be a kind of method that can effectively process VOCs and foul smell contained in waste gas.
Secondly, if use incinerator to incinerate the volatile organic matter (as shown in the following chart all) of nitrogenous and/or sulfur-bearing, must be as shown in Figure 1, and add the clean unit again 20 in order to denitration and/or desulfurization in the downstream of incinerator 10, by the derivative pollution thing (nitrogen oxide (NOx) and/or oxysulfide (SOx)) incinerating after burning, then after purifying just to airborne release; But due to the clean unit again 20 in order to denitration and/or desulfurization, its operating temperature has the restriction of minimum temperature, generally must more than 200 ℃ (be preferably between 300 ℃～400 ℃), just can obtain preferably purification efficiency, if especially derivative pollution thing is oxysulfide (SOx), separately there is the problem of acid corrosion dew point must be noted that; And the purification techniques again of this derivative pollution thing is public technology, do not repeat them here; Yet this air-flow of clean unit 20 again of flowing through, is controlled at the exit flow temperature of incinerator 10 this again more than the required operating temperature (200 ℃ as the aforementioned) of clean unit 20, to reach the effect purifying again conventionally; Therefore via this purifying gas flow temperature that clean unit 20 discharges again still very high (may between 200 ℃～400 ℃), recuperation of heat utilization in addition more completely.
Moreover; in order to prevent incinerator entrance side higher boiling volatile organic matter residual; and produce, shut down vexed combustion problem or coking (Tar) phenomenon; general incinerator (particularly heat accumulating type incinerator) all needs regularly for incinerator by promoting gas flow temperature to carry out high warm mould drying formula (Bake outprocess), by residual higher boiling volatile organic matter in addition heat dry desorption.
