Description
Technical Field
The utility model relates to a stable automatic flushing device for a pH meter.
Background
The PH meter is the key device of desulfurization absorption tower system, is the indispensable device of maintaining absorption tower system normal operating, is often used for measuring the PH value in the absorption tower, flows into the PH meter jar through the thick liquid, measures the interior PH value of absorption tower, guarantees to measure accurately. Because the thick liquid deposits and blocks up easily when flowing through the pipeline, so need set up the sparge water and wash the PH meter, guarantee pipeline and PH meter jar do not take place thick liquid deposit and jam phenomenon.
In order to ensure that the PH meter is not blocked, the PH meter needs to be regularly washed, and because the washing water door of the PH meter, the slurry inlet door and the drain door are all manual doors at the present stage, the inspection on-site operation is required to be arranged during each washing, the operation amount of personnel is increased, and whether the pipeline is blocked or not can not be judged during the interval of the washing of the inspection personnel, and the situation of inaccurate measurement of the PH meter within a certain time can exist; therefore, the stable automatic flushing device for the pH meter is provided to solve the problems.
Disclosure of Invention
The utility model aims to provide a stable automatic flushing device for a pH meter. The deposition flow rate of the slurry can be judged, and the pipeline blockage can be judged through the condition that the flow is automatically reduced in the normal operation stage.
The above purpose is realized by the following technical scheme:
a stable automatic washing device for a pH meter comprises: the device comprises a slurry inlet pipeline and a PH meter tank, wherein the side surface of the PH meter tank is connected with the slurry inlet pipeline, the lower part of the PH meter tank is connected with a flushing water inlet pipeline and a PH meter tank outlet pipeline through a three-way pipe, and the PH meter tank is respectively connected with a first PH meter and a second PH meter; the PH meter tank outlet pipeline is respectively connected with a PH meter tank outlet pipeline manual door, a PH meter tank outlet pipeline pneumatic door and a PH meter tank outlet pipeline flowmeter; the flushing water inlet pipeline is respectively connected with a flushing water inlet manual door and a flushing water outlet pneumatic door; and the slurry inlet pipeline is respectively connected with a manual diaphragm valve and a slurry inlet pneumatic door.
The stable automatic PH meter washing device is characterized in that the pipe diameter of the slurry inlet pipe is larger than the pipe diameters of a washing water inlet pipeline and a PH meter tank outlet pipeline.
The utility model has the beneficial effects that:
1. the utility model provides a stable automatic PH meter flushing device, an automatic control system of the device can realize automatic flushing through logic setting, judge the blocking condition of a pipeline through the flow reduction condition of a PH meter outlet flowmeter, reduce the flow speed in the PH meter pipeline through different pipe diameters of an inlet pipeline and an outlet pipeline, and ensure the measurement time of a PH meter, thereby ensuring the accurate measurement of the PH value.
2. The method avoids manual operation, prevents pipeline blockage, overcomes the defects of the traditional manual flushing, ensures stable flushing time, finds pipeline blockage in time, effectively reduces labor intensity, improves production efficiency, and ensures long-time automatic operation of equipment after starting.
3. The utility model is used for installing the PH meter tank and the corresponding equipment on the absorption tower body to realize the accurate measurement of the PH value of the slurry of the absorption tower, and simultaneously, the tank body and the pipeline are ensured to be smooth and the PH meter head is ensured to be clean by regularly washing the PH meter tank and the corresponding pipeline, thereby ensuring the accurate measurement of the PH value. The operator can judge the current blockage condition of the pipeline through the flow value displayed by the flowmeter so as to decide whether to perform manual intervention, so that the smoothness of the PH meter tank pipeline is ensured, and the accuracy of PH value measurement is further ensured.
4. The working principle of the utility model is as follows:
the flowmeter is used for monitoring the flow that flows through the PH meter pipeline in operation, because the theory of operation of PH meter, the measurement of PH value is more accurate under low velocity of flow state, and we slow down the thick liquid velocity of flow through increasing PH meter jar entry pipeline aperture and reducing PH meter jar export pipeline aperture, but the thick liquid probably deposits under low velocity of flow state, so need maintain the pipeline through the flowmeter and operate under the state of low velocity of flow but not deposit in the operation. And in the normal operation stage, when the flow is automatically reduced, the pipeline can be judged to be blocked, and automatic flushing and back flushing are started through a manual bypass program set by program control. When the flow rate is lower than a certain value in the normal operation stage, the time delay of 30S automatically enters the program control of washing and back washing, and an acousto-optic alarm is given out to ensure that the pipeline is smooth.
