Abstract
The utility model provides a high-abrasion-proof-performance desulfuration seriflux pH value measuring device. A PH meter serves as a key component used for measuring the pH value of the desulfuration seriflux; the high-abrasion-proof-performance desulfuration seriflux pH value measuring device is characterized in that a desulfuration seriflux flow-through pool is arranged on the measuring device, the desulfuration seriflux flow-through pool is provided with four passages, namely an upper passage, a lower passage, a left passage and a right passage, a flange is arranged at each passage opening, and the left passage and the right passage slope downwards to form an angle of 45 degrees to 60 degrees; the seriflux inflows through the lower passage, most of the seriflux flows out from the left passage and the right passage, and a small part of the seriflux flows out from the upper passage; the pH meter is connected onto the back of the flange of the upper passage opening, so that the smooth measuring environment of the pH meter is formed, and the measuring accuracy of the pH meter is guaranteed.
Description
Technical field
The utility model relates to a kind of pH value measurement mechanism, particularly discloses a kind of high abrasionproof performance desulfurization slurry pH value measurement mechanism, is applied to heat-engine plant wet flue gas desulfurization industry lime stone---and the pH value in gypsum wet desulfurization is measured.
Background technology
In wet process of FGD, pH meter is as gypsum slurries pH measurement instrument important in wet desulfurizing process control flow, widespread use in wet desulfurization system.Suitable pH value can make lime stone slurry and flue gas that sufficient chemical reaction occurs, and makes the smooth crystallization of gypsum slurries in desulphurization system.Therefore the accuracy of pH value and security directly affect safety, the economical operation of whole desulphurization system.Because the relative particle of limestone-gypsum slurries in desulphurization system is large and contain chlorion, very easily fouling, washes away, weares and teares the electrode of pH meter and be very serious.
After desulfurizing item puts into operation, because the mounting means of pH meter is improper, cause well adapting to the working environment of desulphurization system.Common mounting means does not wash clean the easy fouling punching of pH electrode, and the measured value of pH meter drifts about greatly, measures inaccurate.And electrode and the fragile difficult point that becomes desulphurization system analysis to measure.
Summary of the invention
The purpose of this utility model is the problem that the pH meter mounting means of solution prior art easily causes glass electrode fouling and wearing and tearing, design a kind of high abrasionproof performance desulfurization slurry pH value measurement mechanism, from the viewpoint of desulphurization system lime stone---the difficult flushing of the easy fouling of gypsum slurries, the large pH meter easy to wear of particle etc., change the mounting means of pH meter, improve the Measurement sensibility of production system to pH value and the serviceable life of pH meter.
The utility model is achieved in that a kind of high abrasionproof performance desulfurization slurry pH value measurement mechanism, pH meter is the critical component of the pH value for measuring desulfurization slurry, it is characterized in that: described measurement mechanism arranges a desulfurization slurry flow cell, described desulfurization slurry flow cell is provided with, under, left, right four passages, each passway is equipped with flange, left, it is sagging that right passage is 45 °～60 ° inclinations, slurries flow into from lower channel, major part left, right two wing passages flow out, fraction flows out from upper channel, described pH meter is connected to the behind of upper channel mouth flange, form the steady measurement environment of pH meter, ensure the accuracy that pH meter is measured.
The beneficial effects of the utility model are: the utility model passes through lime stone---the composition of gypsum slurries, performance, the factor such as relation and the pressure in desulphurization system between flow velocity and precipitation is carried out the analysis of system, calculate research, withstand voltage in conjunction with pH meter itself, shock resistance, the characteristic such as wear-resisting, pH meter installation site is innovated, change the mounting means of original pH meter in duct survey, change flow cell mode of the present utility model into, making the lime stone in pipeline---gypsum slurries enters from the bottom of flow cell, be back to pipeline from the both sides of flow cell, the steady circulation that had so both guaranteed slurries does not have precipitation and accumulates in flow cell, can control again the flow velocity of slurries, reduce lime stone---too fast the washing away pH meter glass electrode of gypsum slurries flow velocity.Use the utility model device can guarantee well the working environment of pH meter glass electrode, guarantee the security of pH meter glass electrode and the accuracy that pH value is surveyed.And then security and the economical operation of whole desulphurization system are guaranteed.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, desulfurization slurry flow cell; 2, lower flange; 3, left flange; 4, right flange; 5, upper flange; 6, pH meter interface.
Embodiment
With reference to the accompanying drawings, pH meter is the critical component of the pH value for measuring desulfurization slurry.A kind of high abrasionproof performance desulfurization slurry pH value measurement mechanism of the utility model arranges a desulfurization slurry flow cell 1, desulfurization slurry flow cell 1 is provided with, under, left, right four passages, and correspondence is provided with upper flange 5, lower flange 2, left flange 3 and right flange 4, left, it is sagging that right passage is 45 °～60 ° inclinations, slurries flow into from lower channel, major part left, right two wing passages flow out, fraction flows out from upper channel, pH meter is connected to the behind of the upper flange 5 of upper channel mouth by pH meter interface 6, form the steady measurement environment of pH meter, ensure the accuracy that pH meter is measured.
The utility model is by changing the mounting means of original pH meter in duct survey, making the lime stone in pipeline---gypsum slurries enters from the bottom of desulfurization slurry flow cell, be back to pipeline from the both sides of desulfurization slurry flow cell again, the steady circulation that had so both guaranteed slurries does not have precipitation and accumulates in flow cell, can control again the flow velocity of slurries, reduce lime stone---too fast the washing away pH meter glass electrode of gypsum slurries flow velocity.Use the utility model device can guarantee well the working environment of pH meter glass electrode, guarantee the security of pH meter glass electrode and the accuracy that pH value is surveyed.And then security and the economical operation of whole desulphurization system are guaranteed.
