Description

A kind of multistage integratedization coking emission-control equipment
Technical field
A kind of multistage integratedization coking emission-control equipment, belongs to coking waste gas treatment equipment field.
Background technology
China is the complicated country of an energy resource structure, but at present, coal and oil product consumption exist always In occupation of consequence in China's energy resource structure.In conventional petroleum technique, coking process is always a kind of important residual oil Process, bears the lighting of heavy oil, and one of its product petroleum coke is widely used in steel, metal refining industry, at present Progressively develop in terms of new material is produced.On the other hand, the rich coal resources of China, are recognizing coal resources high efficiency profit With and grade of oil severeization and petroleum industry price upheaval, the development of Chemical Industry is increasingly by every country Attention.One of important means that carbonization of coal is converted as coal, meeting product market will go to the high-quality of coke chemicals, together When coke chemicals coke be always social heavy industry development high requirement product.Since 21 century, China's chemical industry stone Oil and coal industry occur advancing side by side the trend of development, and either residuum coking or carbonization of coal is all born important Mission, but coking industry is also one high consumption, highly water intensive and high pollution industry, deals carefully with technology waste gas and environment Relation pair national economic stability and energy security guarantee have great importance.
The pollution control problem in chemical industry coking field can not be ignored as China's prevention and cure of pollution problem.It can be produced in coking Raw many pollution environment and the toxic gas for damaging human physical and mental health, such as SO2And NOxAcid rain can be formed by being discharged into air Or acid mist, while can also damage the ozone layer and wait simultaneously, be accompanied by during system is burnt greatly with hydrocarbon formation optical smoke Amount dust pollution thing is discharged into air, once amount is big and spreads apart to suck respiratory tract by people, can cause breathing problem. According to national environmental protection method and《Coking chemistry emission of industrial pollutants standard》Regulation, discharge waste gas in particulate matter, sulfur dioxide and The concentration of nitride should be strict controlled in Solid≤50mg/m3, SO2≤50mg/m3And NOx≤500mg/m3.The burnt flue gas of system is different In other waste gas, its dust-laden, SO2Content is not high, NOxContent is unstable, and flue-gas temperature is at 160 DEG C ~ 300 DEG C, existing waste gas Reason mode is broadly divided into independent desulphurization denitration, and joint carries out desulphurization denitration, and its subject matter is exactly not account in flue gas The processing of grain pollutant and floor space are big, and cost of equipment is high, and operating maintenance expense is big, and it is empty that the field possesses certain lifting Between.
The content of the invention
The technical problems to be solved by the invention are:The deficiencies in the prior art are overcome there is provided a kind of three-in-one integrated, it is synchronous Particulate pollutant, desulphurization denitration in flue gas are handled, the multistage one of floor space and equipment investment expense and maintenance cost is reduced Body coking emission-control equipment.
The technical solution adopted for the present invention to solve the technical problems is:A kind of multistage integratedization coking exhaust-gas treatment dress Put, it is characterised in that:Including the pre- dedusting section being linked in sequence, one-level spray-absorption section and two grades of spray-absorptions sections, pre- dedusting section, One-level spray-absorption section and two grades of integral inclined settings of spray-absorption section;Between two grades of spray-absorption sections and one-level spray-absorption section Provided with one-level transition apparatus, two grades of spray-absorption section other end connection gas-liquid separation dischargers.
