Background technology
China is a phosphorus production big country, domestic have last hundred tame phosphorus production factories, total output occupies first place in the world, yellow phosphorus can produce a large amount of tail gas in the process of smelting, these tail gas are rich in carbon monoxide, has higher calorific value, but yellow phosphoric tail gas complicated component, the purification difficulty is big and investment is many, the manufacturing enterprise of therefore a lot of yellow phosphorus all selects directly tail gas emptying to be burnt, cause the energy so on the one hand, the waste of resource, contaminated environment on the other hand, do not meet the requirement that national energy-conserving and environment-protective are developed a circular economy, especially implemented in 2009 to have stipulated that clearly yellow phosphoric tail gas can not in linely burn since " yellow phosphorus industry access condition ", therefore, the recovery of yellow phosphoric tail gas and utilized unprecedented height referred.
At present, nearly all phosphorus production enterprise carries out resource to yellow phosphoric tail gas and rationally utilizes, all dispose corresponding yellow phosphoric tail gas recycling system, but all be difficult to reach the yellow phosphoric tail gas comprehensive utilization ratio of national requirements in the standard more than 90% because of system's self-defect.
The utility model content
The purpose of this utility model is to provide a kind of yellow phosphoric tail gas recycling system, and it has the high characteristics of recovery utilization rate.There is the problem that is difficult to reach national energy-conserving and environment-protective requirement in the yellow phosphoric tail gas recycling system in the prior art to solve.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of yellow phosphoric tail gas recycling system, it comprises the tail gas preprocessing system, combustion system and heat recovery system, wherein, described tail gas preprocessing system comprises liquid packing, described liquid packing is connected with the alkali liquid washing tower by vavuum pump, described alkali liquid washing tower by pipeline with dehydrate device and be connected, described combustion system comprises burner, one end of described burner by the control valve group with dehydrate device and be connected, the other end is connected with adiabatic incinerator, and described burner also is connected with air blast, and described heat recovery system comprises waste heat boiler and economizer, one end of described waste heat boiler is connected with adiabatic incinerator, and the other end connects economizer.
Especially, described yellow phosphoric tail gas recycling system also comprises the flue gas after-treatment system that is connected with heat recovery system.
Especially, described flue gas after-treatment system comprises acid separator, air-introduced machine and chimney, and described acid separator is connected with economizer, and described air-introduced machine is arranged between acid separator and the chimney.
Especially, described chimney is anticorrosion chimney.
Especially, described waste heat boiler is an open type burner hearth waste heat boiler.
The beneficial effects of the utility model are, described yellow phosphoric tail gas recycling system compared with prior art not only disposes the pernicious gas in the yellow phosphoric tail gas, fuel gas is burnt and utilizes waste heat boiler to reclaim heat, and the gas after will burning carries out the later stage and removes acid treatment before entering atmosphere, makes the waste gas that finally enters atmosphere become the gas of harmless environmental protection.The recovery utilization rate height of the yellow phosphoric tail gas of this system satisfies national energy-conserving and environment-protective requirement.
