Background
Nitrogen oxides and sulfur dioxide are the main pollutants of various types of flue gases. The emission of nitrogen oxides and sulfur dioxide into the atmosphere not only directly harms human health, but also causes a series of environmental problems such as haze, acid rain, photochemical pollution and the like, so that the control of the emission of the nitrogen oxides and the sulfur dioxide is very important for improving the quality of the atmospheric environment.
Mainstream technologies for flue gas desulfurization and denitration include wet flue gas desulfurization, SCR flue gas denitration, activated carbon/coke flue gas desulfurization and denitration, flue gas circulating fluidized bed desulfurization and denitration, and the like. The wet flue gas desulfurization mainly adopts a limestone or lime-gypsum method, an ammonia method, a seawater desulfurization method and the like. The limestone or lime-gypsum method is the most widely used wet flue gas desulfurization technique, and has the advantages of high desulfurization efficiency, good operation reliability, wide absorbent source, low price and the like. SCR flue gas denitration technique has advantages such as denitration efficiency is high, area is little, but conventional SCR flue gas denitration technical requirement temperature is higher, if reaction temperature is low excessively, not only influences denitration efficiency, and more importantly the catalyst is easily poisoned. In order to cope with industrial furnace flue gas with low temperature and complex components and places where an SCR denitration system is not suitable to be arranged, in recent years, technologies such as activated carbon/coke flue gas desulfurization and denitration, flue gas circulating fluidized bed flue gas desulfurization and denitration and the like are popularized and applied.
The activated carbon/coke flue gas desulfurization and denitrification technology has the advantages of purifying various pollutants, and has high purification efficiency, but the activated carbon/coke has higher cost and complex circulation and regeneration processes, so that the system failure rate is higher. The flue gas circulating fluidized bed technology has high purification efficiency, but the denitration efficiency guarantee rate is relatively low, and the problems of high system failure rate and the like are also faced. Based on this, people propose ozone oxidation and absorb flue gas desulfurization denitration technique in coordination, this technique utilizes ozone to oxidize nitric oxide into high valence state's nitrogen oxide earlier, utilizes conventional wet flue gas desulfurization system to realize high-efficient SOx/NOx control, and this technique adopts the two-phase contact of air current to realize the desorption of pollutant, and the guarantee rate that the system does not have trouble operation is higher.
In the process of desulfurization and denitrification, one of the reasons for influencing the quality of the whole process flow when a desulfurization tower or a denitrification tower nozzle is blocked is that the blockage of the desulfurization tower nozzle is mainly caused by residues in the tower, including glass fiber reinforced plastic resin residue fragments, ash residues and the like.
CN 106215610A discloses flue gas desulfurization tower filter of edulcoration can be indicateed, including box, import pipe, outlet pipe and built-in filter screen, be equipped with import pipe and outlet pipe on two relative sides of box respectively, import pipe and outlet pipe all communicate the inside of box, the inside of the parallel setting in box of section of built-in filter screen and import pipe, the inside of box is provided with two cavities. Flue gas desulfurization tower filter reduces the problem that SOx/NOx control tower nozzle blockked up through set up the filter screen between inlet and liquid outlet, but the filter screen is with high costs, needs to change on an irregular basis, is unfavorable for improving SOx/NOx control system's operating efficiency.
CN 208493429U discloses a desulfurization slurry filter, including casing and inner tube, the inner tube set up in the casing, the casing lateral wall is provided with inlet and liquid outlet respectively, the inner tube lateral wall is provided with the through-hole, the through-hole with the inlet laminating intercommunication, the inner tube intracavity is provided with a scraper blade, be provided with a plurality of flow control on the scraper blade, the casing outside is provided with drive arrangement, drive arrangement can drive the scraper blade rotates and the up-and-down motion, and it is right to utilize the epitaxial part that cleans of scraper blade side the inner tube inner wall cleans. Although the desulfurization slurry filter can reduce the blocking probability of the through hole of the inner cylinder, filter residues still contain a large amount of slurry and moisture, and the desulfurization slurry filter is easy to cause the waste of a large amount of absorption slurry during filtering.
Therefore, the inner cylinder type slurry filtering device can stably operate for a long time, and useful components in slurry can be effectively recycled, so that the stable operation of a desulfurization and denitrification system is facilitated.
