Description
Technical field
The invention belongs to the emission control technique of coal-fired flue-gas fine particle, heavy metal and the condensable property material of field of environment protection, especially relate to a kind of charged adsorbent and strengthen the method for electric bagging apparatus the Collaborative Control of flue gas multiple pollutant.
Background technology
PM
2.5Pollution problem caused the society show great attention to.As global PM
2.5One of the highest area, China in " ambient air quality " revised recently clearly with PM
2.5Pollution is as the monitoring and evaluation object.Therefore, PM
2.5To become the main task of several years Air Pollution Control from now on, its technical research and application will become one of the most important work in atmosphere environmental protection field.And fire coal and Industrial Stoves flue gas are to cause PM
2.5Main cause Deng the fine particle discharging; And this type is via not only containing the particle (being called the filtrability particle) that is solid-state under the hot flue gas in the flue gas that high temperature produced; Under hot flue gas, be gaseous state but also contain part; Be solid-state or liquid particle under environment temperature or the moisture condition but be cooled to, this type material is a condensable property material.Belong to comprising of condensable property material in the flue gas: components such as volatility inorganic matter (like the halide of element), high boiling organic matter (like polycyclic aromatic hydrocarbon and trace type tar component), sulfur trioxide and part volatile heavy metal.Wherein, because the generally use of SCR denitrification apparatus causes S0 in the flue gas
3Concentration increases, and very fast moisture absorption was converted into fine particle after it got into atmosphere.For the many operations (generally being higher than 100 ℃) under hot flue gas situation of the dust arrester of routine, can be by effective removal be the bigger filtrability particle of particle.
Simultaneously, China is one of the most serious country of heavy metal pollution, and the wherein coal-fired mercury emissions problem that is caused is particularly outstanding.Along with the aggravation of pollution condition and the signature soon of international control mercury pact, fire coal boiler fume is carried out mercury emissions control become domestic and international common recognition.China has formally issued " heavy metal pollution integrated control " 12 " planning " and " thermal power plant's atmosphere pollutants emission standards " at present, and emission control has proposed strict requirement to mercury pollution.And fine particle or condensable property particle are the principal modes of heavy metals emission in the flue gas.Therefore, control coal-fired fine particle and condensable property particle and have uniformity and concertedness with the discharging of controlling heavy metal contaminants.
At present mainly adopt electrostatic precipitator and sack cleaner two kind equipments for the removal of particle in the coal-fired flue-gas.Electrostatic precipitator is better to the bigger flue dust removal effect of particle, but not ideal enough to the removal efficient of fine particle, is difficult to satisfy the technical need of the efficient control of fine particle; The efficiency of dust collection of bag-type dusting is higher, and fine particle is had removal effect preferably, but because dust concentration is higher, causes the bag-type dusting deashing frequent, reduces the service life of filter bag, and has increased the management difficulty of stable operation.And electricity bag composite dedusting device (the dedusting combination of electric back pkt. before promptly adopting), solved preferably electric cleaner or sack cleaner use separately existing questions (utility model patent, 200420040846.X).But existing electricity bag composite dedusting device is still not high enough to the removal efficient of fine particle, is difficult to satisfy PM
2.5The technical need of efficient control, not good to the removal effect of heavy metal Hg in the flue gas (existing) and condensable particle simultaneously with fine particle or gaseous form.In addition, because the electricity district of electricity bag composite dedusting and bag district structurally can separate, and most of flue dust can be removed in the electricity district, thereby can be the collaborative removal of using adsorbent to carry out multi-pollutant in the bag district advantage is provided.
At present,, can adopt the method for electric coalescence to promote the fine grained in the flue gas to reunite with becoming bigger particle, remove efficient thereby help improving fine particle for strengthening the removal efficient of fine particle.Research is arranged for improving the arresting efficiency of electric cleaner, before electric cleaner or set up charged and coalescence electric field region (number of patent application between two adjacent electric fields to fine particle; 200410066936.0), but this method can significantly increase the equipment investment of electric cleaner and take up an area of the space.The design feature of researching and proposing at electricity bag composite dedusting device is arranged recently; Strengthen electric field through between electricity, bag district, setting up charged coalescence, and in this electric field, spray into certain adsorbent and improve removal efficient (number of patent application: 201110257729.3) fine particle.This invention can promote fine grain removal to a certain extent, and the use of adsorbent also has certain effect to the removal of mercury.But the electricity bag set composite to general increases the physical dimension that a coalescence electric field can obviously increase dust arrester again between Qi Dian district and bag district.In addition, use a just high electric field separately, can not obtain coalescence effect preferably.In addition, because the coalescence district arranges a large amount of electrodes, adsorbent sprays to this district that difficulty is evenly distributed, and sprays the adsorbent of coming in and can be captured by the coalescence electrode very soon, makes it not high at demercuration and utilization rate of capturing aspect the fine particle.
