Description
Technical field
The utility model relates to a kind of gypsum slurries in the wet flue gas desulfurizer trunk line, detecting instrument of lime stone slurry of being used for, particularly a kind of serous fluid processed by wet flue gas desulfurization density, pH value measurement mechanism of measuring accurately, being convenient to online flushing and maintenance.
Background technology
At present, in the wet flue gas desulfurizer operational process, for guaranteeing desulfurizer reliability of operation and flue gas desulfurization effect, must detect the gypsum slurries that the flue gas desulfurization effect is played a decisive role in the desulfurizer, the density and the pH value of lime stone slurry.The densitometer that existing detecting instrument adopts is directly installed on the trunk line separately; pH meter is installed on the absorption tower; cause density to take into account the damage of pH meter easily, influence its serviceable life and usability, damage the problem that causes a whole set of desulfurizer to be shut down in case exist density to take into account pH meter.Because densitometer and pH meter belong to exact instrument, want to make measured value more accurate, must carry out periodic flushing and maintenance to it, so that keep having suitable slurries speed in the desulfurizer pipeline, improve operation stability, prevent fault.Existing desulfurizer since densitometer be directly installed on separately on the trunk line, can't accurately measure and controlling plumbing fixtures in slurries speed in the scope that instrument allows, can not realize online flushing and maintenance, make its lost of life; And pH meter is installed on the absorption tower, and its installation pipeline is mobile poor, causes pipeline obstruction easily, thereby influences the accuracy that the pH value is measured.So, need exploitation to be fit to densitometer, the pH value measurement mechanism of the wet flue gas desulfurizer of China's actual conditions at present.
The utility model content
The purpose of this utility model provides a kind of serous fluid processed by wet flue gas desulfurization density; the pH value measurement mechanism; the densitometer and the pH meter that have solved existing wet flue gas desulfurizer existence can not be realized online flushing; easily block; influence measuring accuracy; cause defectives such as equipment downtime; its reasonable in design; can guarantee that density takes into account pH meter and move in the pipe flow speed scope that instrument allows; be convenient to online flushing and maintenance; significantly improve accurate measurement to the desulfurization slurry detected value; be beneficial to flue gas desulfurization qualified discharge and stable equipment operation, fundamentally eliminate the problem that sweetener is shut down, prolonged the serviceable life of instrument simultaneously.
The technical scheme that the utility model adopted is: this serous fluid processed by wet flue gas desulfurization density, the pH value measurement mechanism comprises the conveying gypsum slurries, the densitometer of the trunk line of lime stone slurry and measurement slurries, pH meter, tested slurries are sent into reflux line and the joint flange and the bend pipe of slurries baffle-box, its technical essential is: on the described trunk line take-off pipe is set, and by described take-off pipe and described joint flange, bend pipe carry out that order is communicated with to the folder motorized valve, diaphragm valve and support tube and described reflux line are formed the slurries closed circuit, described take-off pipe to the folder motorized valve, the wash tub pipe of connection is set between the diaphragm valve, sidewall at described take-off pipe is communicated with described densitometer, the wash tub pipe of connection is set on described support tube sidewall, and described pH meter is arranged in the support tube.
Reflux line in the described slurries closed circuit is communicated with two groups of diaphragm valves and pH meter support tube respectively, and utilizes threeway and have densitometric described take-off pipe and be communicated with.
Advantage and the good effect that the utlity model has are: because the utility model is in same set of slurries closed circuit, by take-off pipe and joint flange carry out that order is communicated with to folder motorized valve, diaphragm valve and support tube, packing density meter, pH meter, so its reasonable in design, can not only guarantee that density takes into account pH meter and move in the pipe flow speed scope that instrument allows, and it is little to take up room, and easy operating control is convenient to safeguard and maintenance.In addition; because of take-off pipe to the folder motorized valve; the wash tub pipe of connection is set between the diaphragm valve; the wash tub pipe of connection is set on pH meter support tube sidewall; therefore be readily embodied in line flushing and maintenance; can significantly improve accurate measurement to the desulfurization slurry detected value; reduced the whole accident frequency of shutting down of wet flue gas desulfurizer; be beneficial to flue gas desulfurization qualified discharge and stable equipment operation; can not realize online flushing from the densitometer and the pH meter that have solved existing wet flue gas desulfurizer existence at all; easily block; influence measuring accuracy, cause defectives such as equipment downtime, prolonged the serviceable life of instrument simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Sequence number explanation among the figure: 1pH meter, 2 diaphragm valves, 3 wash tub pipes, the 4 pairs of folder motorized valves, 5 densitometers, 6 threeways, 7 trunk lines, 8 support tubes, 9 joint flanges, 10 reflux lines.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1.This serous fluid processed by wet flue gas desulfurization density, pH value measurement mechanism comprise trunk line 7 and measure the densitometer (mass flowmeter/densitometer) 5 of slurries, pH meter 1, reflux line 10 and a plurality of joint flange 9, diaphragm valve 2 and bend pipe are to parts such as folder motorized valve 4 and support tubes 8.Wherein carry on the trunk line 7 of gypsum slurries, lime stone slurry take-off pipe is set, and will carry out order to folder motorized valve 4, diaphragm valve 2 and support tube 8 by take-off pipe and joint flange 9, bend pipe and be communicated with, then with the reflux line 10 composition slurries closed circuits of tested slurries being sent into the slurries baffle-box.Diaphragm valve 2 is for breaking down at densitometer or pH meter, safeguards and closes that the localized branches pipeline is provided with when overhauling.Take-off pipe to folder motorized valve 4, diaphragm valve 2 between the wash tub pipe 3 of connection is set.Be communicated with densitometer 5 at the sidewall of take-off pipe, gypsum slurries, the lime stone slurry of flowing through in it carried out the measurement of serum density, connect wash-down water with wash tub pipe 3 interfaces simultaneously diaphragm valve 2, the take-off pipe etc. that has a densitometer 5 are carried out online flushing.The wash tub pipe 3 of connection is set on support tube 8 sidewalls, connects wash-down water with wash tub pipe 3 interfaces pH meter is carried out online flushing.PH meter 1 is arranged in the support tube 8, and the gypsum slurries in it of flowing through, the pH value of lime stone slurry are measured.PH meter 1 can be provided with two, also can be provided with one.Normal operation for not overslaugh slurries closed circuit, can be with the reflux line in the slurries closed circuit 10 and two groups of independently shunt of diaphragm valve 2 and support tube 8 compositions that have pH meter 1 separately, be communicated with respectively, and utilize threeway 6 that two shunt are communicated with the take-off pipe that has densitometer 5.When single pH meter 1 breaks down when need removing, can close and this side corresponding diaphragm valve 2 along separate routes, this pH meter 1 is safeguarded and keeped in repair.
