Description
Technical field
The utility model belong to machinery equipment field more particularly to a kind of flue gas wet flue gas desulfurization gypsum slurries in line density and
PH value combined measurement device.
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, in Limestone-gypsum Wet Flue Gas Desulfurization Process system, gypsum slurries density
It is two important parameters of Limestone-gypsum Wet Flue Gas Desulfurization Process with pH value, operation, the control of whole system is played vital
Effect.Gypsum slurries pH value is one of the main control parameters of Limestone-gypsum Wet Flue Gas Desulfurization Process technique, to the shadow of desulfuration efficiency
Sound is the most significant, and selecting suitable pH value is one of the key factor that guarantee system is well run.Under normal circumstances, absorption tower is starched
Liquid pH value should control between 5.0~5.4.In actual operation, it should find and this desulphurization system pH value is suitble to operate control range,
While the indexs such as desulfuration efficiency reach requirement, system energy consumption is reduced.Serum density control is mainly by keeping absorption tower
Output balance, the slurries delivery flow on absorption tower is controlled to realize.It is absorbed simultaneously by adjusting to return from hydrocyclone
The spillway discharge and underflow slurry liquid measure of tower carry out stable slurry density.The stable desulfuration efficiency for improving system of holding serum density,
The quality of by-produced gypsum and equipment scaling is prevented to be advantageous.Gypsum slurries density is controlled in operation in a suitable model
(1080~1100kg/m in enclosing3), be conducive to the efficient, economic of desulphurization system and safe operation.It controls and joins in view of two above
Several importance, it is therefore necessary to configure on-line continuous combined measurement device, realize gypsum slurries pH value that absorption tower be discharged with
The accurate measurement of density, to guarantee the safe and stable operation of desulphurization system.
Desulfurizer gypsum slurries pH value is often with measurement method at present: installing on gypsum slurries slurry pump outlet conduit
Branch pipe installs plug-in type pH electrode on branch pipe, while introducing flushing water, rinses pH electrode.The disadvantage is that: pH electricity in outlet conduit
Slurry flow rate at pole is higher, fluid erosion electrode easy to wear；Rinse mouth face electrode, the interior water flow velocity that rinses of pipeline is larger, meeting
Impact failure electrode, causes glass electrode to rupture when serious, is not available；Gypsum particle causes to dismantle in surrounding them fouling
Difficulty is not easy to periodic calibrating.When system shutdown for a period of time when, also need a pH electrode to remove and be immersed in the water protection, otherwise
Exposure in air, will affect measurement accuracy, will lead to electrode failure when serious and scrap electrode for a long time.This increases operation and maintenance
Personnel's maintenance.
Desulfurizer gypsum slurries density often with measurement method is set on the outlet conduit of gypsum slurries discharge pump at present
A bit of slurries shunt valve is set, slurries are introduced into shunt valve, density measure is carried out by duct type mass flowmenter.But it bypasses
The caliber of pipeline is smaller, and there is strict demand in while measuring serum density to flow velocity, and deposition, blocking measurement are also easy to produce when flow velocity is low
Pipe；When flow velocity is high slurries to measurement transducer wall's abrasion it is larger, influence measurement accuracy, when serious can worn out measurement pipe, lead to quality stream
Meter is scrapped.The caliber difference of shunt valve and main pipeline can make the slurry flow rate of measurement point generate biggish fluctuation, be difficult to control,
Therefore cause mass flowmenter that cannot run steadily in the long term.
Gypsum slurries density and pH value cannot reliable, accurately on-line measurement, desulphurization system just can not timely for slurry and
Plasma discharge, pH value is too low also to will cause that system corrosion is serious, reduces the service life of equipment, in addition make desulphurization system be difficult to it is economical,
The operation of safety.Therefore, a kind of low-maintenance, consistently online, high accurately gypsum slurries density and pH value combined measurement dress are developed
It sets, is those skilled in the art's technical problem urgently to be resolved.
