Description
Technical field
The utility model relates to environment protection desulphurization technical field more particularly to a kind of sodium alkali desulfurization slurry piping filters.
Background technique
Recent years, with the serious of environmental pollution, country has put into effect a series of policies and thermal power plant is encouraged to implement to surpass
Low emission transformation, is transformed after-burning coal smoke power-plant flue gas SO2Concentration of emission requires control in 35mg/Nm3Hereinafter, this is to desulphurization system
Safe and economical operation proposes tightened up requirement.
Currently, sodium alkali desulfurization refers to the desulfurization side for making desulfurizing agent using two kinds of alkaline matters of NaOH and lime (CaOH)
Method, existing sodium alkali desulfurization common process are that soda slurries enter spraying layer atomization, atomization slurry directly after circulating pump boosts
Haptoreaction is carried out with flue gas, reaches desulfurization purpose.Sodium alkali desulfurizing byproduct is the mixture of sodium sulphate, sodium sulfite, is taken off
Sulphur tower hold the slurries in liquid bath by long-time recycle after sodium sulphate, sodium sulfite concentration gradually rise, in slurries be easy
Existing crystalline particle, crystalline particle can enter the nozzle of spraying layer by circulating pump, and sodium alkali desulfurization nozzle aperture is smaller, be easy quilt
Crystalline particle blocking.
To solve the above problems, existing method is usually to add one between desulfurizing tower pump inlet valve and pump
Filter device filters out the crystalline particle in sodium alkali desulfurization slurry by the filter device, prevents it by desulfurization nozzle hole plug,
But the filter disc of existing filter device is often non-dismountable, can only filter out the tamper of setting specification, it is larger to there is investment, and filter
The technical problems such as slag reset procedure is time-consuming and laborious.
The Chinese utility model patent of Patent No. 201721536873.X discloses a kind of lime stone slurry filter pipeline
Device, it include filter housings and extend through connection the left and right end of filter housings inlet tube and outlet tube, it is described into

Strainer and the corresponding filter housing top of rear class refined filtration net are equipped with strainer and dismount mouth, with prime coarse strainer and rear class refined filtration net pair
The filter housings bottom answered is equipped with sewage draining exit.Although the strainer of the piping filter of above structure can be dismantled, and can root
The strainer of installation different size is selected according to demand, and can carry out filter residue removing by sewage draining exit, but the present inventor is in practice
It was found that there are still following defects: (1) do not have filter gauze cleaning function, it, can not be in the case where not needing replacement strainer
The strainer of installation is cleaned, it is desirable to complete the cleaning, it is necessary to by strainer after being disassembled in piping filter ability
It is cleaned, just can be carried out subsequent filtration after piping filter to be also installed back after having cleaned, one, which tears one open, washes a dress, takes
When it is laborious, influence equipment operating efficiency；(2) during the filtration process, because slurries have certain viscosity, part filter residue can be adhered to
It on the inner wall of piping filter, can not be discharged, exist because filter residue excludes to influence equipment normal operation due to being not thorough from sewage draining exit
Problem.
Therefore, a kind of sodium alkali desulfurization slurry piping filter is developed regarding to the issue above, and not only there is urgent research
Value, it may have good economic benefit and commercial application potentiality, this be exactly where the power that is accomplished of the utility model and
Basis.
