Description
Technical field
The utility model relates to a kind of desulphurization plant, a kind of specifically circulating sprayer.
Background technology
Magnesia wet desulphurization technology is the sulfur removal technology that a kind of maturity is only second to the calcium method, the magnesia sulfur removal technology all has very many application achievements all over the world, wherein used more than 100 project in Japan, the power station in Taiwan 95% is to use magnesium oxide method, all used on the U.S., Germany and other places in addition, and the achievement of using has been arranged in China some areas at present, but also there are very big development space in quantity, scale and technical merit.
The magnesian reserves of China are very considerable, and present explored magnesia reserves are about 16,000,000,000 tons, account for global about 80% and best in quality.Its resource mainly is distributed in provinces such as Liaoning, Shandong, Sichuan, Hebei, and wherein Liaoning accounts for 84.7% of total amount, secondly is the Laizhou, Shandong, accounts for 10% of total amount, and other mainly is in the great river, Xingtai, Gan Luoyan Mount Tai, Sichuan, Hanyuan, Gansu Su Bei, not Gai etc. ground.Therefore magnesia can be applied to the desulphurization system of power plant fully as desulfurizing agent.
Sulfur method calcium method desulfurization commonly used, calcium hydroxide is not as magnesium hydroxide hydrolysis more thorough (solubility of calcium hydroxide is lower than magnesium hydroxide), aspect chemical reactivity much larger than calcium-based desulfurizing agents such as calcium oxide, calcium carbonate, therefore desulfuration efficiency is higher than the calcium method, can reach more than 95, and the desulfuration efficiency of limestone/gypsum method only reaches about 90～95%.
Because the active potent rate height of magnesia, so magnesia has its unique advantages as desulfurization itself, and comparing with the limestone/gypsum method at the power of the overall size of the size of the structural design on absorption tower, recycle slurry liquid measure, system, equipment can be corresponding less.Therefore the investment cost of whole desulphurization system can reduce more than 30% relatively.
The principal element of decision desulphurization system operating cost is public work energy consumptions such as the consumption of desulfurizing agent and water, electricity.Magnesian molecular weight is all little a lot of than calcium carbonate and calcium oxide, and magnesium be the required magnesia weight of divalent ion so unit desulfurization be reach effect same calcium carbonate 1/3rd, be 1/2nd of NaOH.Because the doctor solution internal circulating load less than its limestone/gypsum method, therefore can significantly reduce the circulating pump power consumption.Though magnesian price is higher than the price of calcium carbonate/calcium oxide, but the SO2 magnesia consumption that removes same weight is 40% of a calcium carbonate; Therefore magnesium oxide method sulfur removal technology operating cost is lower.
The desulfurization of magnesium method is that system the equipment scaling blockage problem can not take place with respect to the sharpest edges of calcium method, can the whole desulphurization system of assurance move safely and effectively, magnesium method pH value is controlled between 6.0～6.5 simultaneously, and the equipment etching problem has also obtained solution to a certain degree under this condition.Generally speaking, the security performance of magnesium method desulfurization in actual engineering can obtain strong guarantee.And because the key reaction product of magnesium method desulfurization is a magnesium sulfite, can carries out forced oxidation easily and generate magnesium sulfate, through concentrating, crystallization, purification generate epsom salt.Be industrial chemicals such as leather, papermaking or sell as the high-quality chemical fertilizer.The epsom salt molecular weight is more than magnesian six times, so yield is the initial magnesian six times of weight that drop into, if be able to purification processes, its income can offset with the input of raw materials of magnesium oxide.If add the sulfur dioxide charges for disposing pollutants of return, the magnesia wet desulfurizing process can reach leveling of income substantially.
And common limestone/gypsum wet desulfurizing process unavoidably can produce the inferior gypsum and the gypsum of inferior quality.Because Chinese gypsum resource is abundant and best in quality, so the outlet of the low desulfurated plaster of quality has a disconcerting prospect, even needs flower energetically with its landfill or abandon, and this also just exists secondary pollution problem.For the magnesia desulfur technology, because byproduct economic benefit height, operation enterprise generally can invest comparatively perfect reprocessing facility, can accomplish the waste water and dregs zero-emission substantially.This has just solved secondary pollution problem.
So based on foregoing, magnesium method desulfur technology and equipment are introduced into domestic, and carry out autonomous design.The utility model is exactly a part of equipment being carried out autonomous innovation.
The utility model content
The utility model provides a kind of desulphurization plant, specifically the circulating sprayer of desulphurization plant.
The purpose of this utility model is to be achieved through the following technical solutions:
Circulating sprayer is made up of desulfuration recycle pump, filter, circulation line and spiral nozzle.Desulfuration recycle pump is placed in the catch pit, the output pipe of desulfuration recycle pump is connected in the treating column, described filter bits is in the top of catch pit, the output pipe for the treatment of column bottom is linked in the filter, the output pipe that treating column connects circulating pump and circulating pump is provided with spiral nozzle, and described spiral nozzle is positioned at the top for the treatment of column.
After the recirculated water that contains desulfurizing agent may stop up the solid matter filtering of shower nozzle through filter, enter in the catch pit, then by catch pit inside desulfuration recycle pump pressurize, be assigned to by the road treating column, be pressed and delivered to each spiral nozzle by the circulating pump that is positioned at the treating column another location; The spiral nozzle that specialized designs is used for desulfurization has the good and not susceptible to plugging characteristics of atomizing effect, and a large amount of ultrafine globule of its ejection fully contacts with sulfur-containing smoke gas, carries out the reaction of comprehensive exchange heat and chemical desulfurization.Guarantee desulfuration efficiency, the desulphurization circulating process needs to carry out continuously and effectively.
