Abstract
一种垃圾焚烧尾气处理方法，具体步骤为：烟气经过第一级湿式脱酸除尘器喷淋脱酸除尘，然后再通过布袋除尘器和活性炭吸收器对烟气进行吸收除尘，然后余下的烟气再经过第二级湿式脱酸除尘器的喷淋脱酸除尘，最后无害气体排到大气中，湿式脱酸除尘器中的废液通过石灰水池的中和之后，经过沉淀再添加碱性药剂，通过循环泵送入湿式脱酸除尘器中用于喷淋酸性气体。本方法采用两级湿式脱酸除尘，并辅以布袋除尘器以及活性炭对烟气进行吸收、净化，产生的废水经过沉淀、添加碱液之后送入湿式脱酸除尘器中循环利用，不仅将烟气中的有害气体除掉，避免其污染大气，而且将废液循环利用，整个循环过程清洁、高效，环保，适合城市乡镇大力推广使用。
A waste incineration tail gas treatment method, the specific steps are: the flue gas is sprayed with a first-stage wet deacidification dust collector to deacidify and remove dust, and then the flue gas is absorbed and dusted by a bag dust collector and an activated carbon absorber, and then the remaining flue gas The gas then passes through the spray deacidification and dust removal of the second stage wet deacidification dust collector, and finally the harmless gas is discharged into the atmosphere. The agent is sent into the wet deacidification dust collector through the circulating pump for spraying acid gas. This method adopts two-stage wet deacidification and dust removal, and is supplemented by bag filter and activated carbon to absorb and purify the flue gas. Harmful gases in the air are removed to avoid air pollution, and the waste liquid is recycled. The entire cycle process is clean, efficient, and environmentally friendly, and is suitable for vigorous promotion and use in cities and towns.
Description
Technical field
The present invention relates to environmental technology field, is a kind of garbage incinerating tail gas processing method specifically.
Background technology
The processing method of house refuse mainly contains landfill, compost, burning etc.In recent years, along with China's expanding economy, the raising of house refuse amount and refuse thermal value, burning disposal method is the most effective waste disposal method.But, containing pernicious gases such as sulfur dioxide, hydrogen chloride, nitric oxide, nitrogen dioxide and dioxin in the tail gas that waste incineration produces, if these pernicious gases are directly discharged in air, will produce air quality and have a strong impact on.Although existing exhaust gas treating method can dispose most pernicious gas, or some pernicious gas is directly discharged in air, brings very large hidden danger.
Summary of the invention
For above-mentioned Problems existing, the object of this invention is to provide a kind of clean, efficient garbage incinerating tail gas processing method.
The object of the invention is to be achieved through the following technical solutions:
A kind of garbage incinerating tail gas processing method, comprises the following steps:
(1) flue gas in incinerator enters into first order wet type depickling deduster, under the spray effect of alkali lye, the temperature of high-temperature flue gas is reduced to less than 450 DEG C rapidly, decrease the generation of dioxin, and remove partially acidic gas in flue gas and bulky grain flue dust by the spray of alkali lye; Remaining flue gas enters into sack cleaner, and the waste liquid of generation enters into lime pond;
(2) waste liquid is after the neutralization in lime pond, after the precipitation of preliminary sedimentation tank and second pond, the waste liquid overflow on top is in circulatory pool, regularly add basic agent in circulatory pool, waste liquid pH value in guarantee circulatory pool is more than 10, then through circulating pump, above-mentioned alkaline waste liquor being delivered in the shower of first order wet type depickling deduster and second level wet type depickling deduster, regularly needing adding clear water in circulatory pool in order to supplement the water evaporated;
(3) remove the dust of in flue gas more than 50 μm through sack cleaner, remaining flue gas enters into activated carbon absorber;
(4) activated carbon absorber sponges dioxin, heavy metallic oxide microparticle and the remaining dust in flue gas;
(5) remaining flue gas is under the effect of air-introduced machine, the interlayer again entering into incinerator heats to 200-300 DEG C, and then enter into second level wet type depickling deduster, depickling dedusting is again carried out under the spray effect of alkali lye, finally discharged through chimney by innocuous gas, the waste liquid of generation enters into lime pond and recycles.
Beneficial effect of the present invention: this method adopts two-stage wet type depickling dedusting, and be aided with sack cleaner and active carbon absorbs flue gas, purifies, the waste water produced is sent in wet type depickling deduster and is recycled after precipitation, interpolation alkali lye, not only the pernicious gas in flue gas is removed, avoid its atmosphere pollution, and utilized by waste liquid circulation, whole cyclic process is clean, efficient, environmental protection, is applicable to small towns, city and vigorously promotes the use.

Fig. 1 is the flow chart of the inventive method.
Detailed description of the invention
The following examples can illustrate in greater detail the present invention, but do not limit the present invention in any form.
Embodiment 1, as shown in Figure 1:
(1) flue gas in incinerator enters into first order wet type depickling deduster, under the spray effect of alkali lye, the temperature of high-temperature flue gas is reduced to less than 450 DEG C rapidly, decrease the generation of dioxin, and remove partially acidic gas in flue gas and bulky grain flue dust by the spray of alkali lye; Remaining flue gas enters into sack cleaner, and the waste liquid of generation enters into lime pond;
(2) waste liquid is after the neutralization in lime pond, after the precipitation of preliminary sedimentation tank and second pond, the waste liquid overflow on top is in circulatory pool, regularly add basic agent in circulatory pool, waste liquid pH value in guarantee circulatory pool is more than 10, then through circulating pump, above-mentioned alkaline waste liquor being delivered in the shower of first order wet type depickling deduster and second level wet type depickling deduster, regularly needing adding clear water in circulatory pool in order to supplement the water evaporated;
(3) remove the dust of in flue gas more than 50 μm through sack cleaner, remaining flue gas enters into activated carbon absorber;
(4) activated carbon absorber sponges dioxin, heavy metallic oxide microparticle and the remaining dust in flue gas;
(5) remaining flue gas is under the effect of air-introduced machine, the interlayer again entering into incinerator heats to 200-300 DEG C, and then enter into second level wet type depickling deduster, depickling dedusting is again carried out under the spray effect of alkali lye, finally discharged through chimney by innocuous gas, the waste liquid of generation enters into lime pond and recycles.
