Abstract

And (4) switching the measuring device for the online sample water. Several sets of equipment are usually used alternately in the water production system, one or more sets of online measuring instruments are always idle under the condition that the whole equipment is not operated to produce water, and the idle equipment also needs to be maintained, so that the unnecessary workload of maintenance personnel is increased. The utility model discloses the constitution includes: the device comprises a cabinet body, wherein a plurality of input pipes (9) are fixed on a lower layer (4) in the cabinet body, the plurality of input pipes are collected to an output pipeline (6), and the output pipeline is communicated to a line measuring instrument (5); each input pipe is provided with a water diversion tee joint (8), and one output of the water diversion tee joint is communicated with a sewage discharge pipe (7). The utility model is used for switch over the measurement at online appearance water.

Description

On-line sample water switching measuring device

The technical field is as follows:

the utility model relates to an online appearance water switches measuring device.

Background art:

the requirement of the thermal power plant on the water quality is very strict, and the analysis instrument for measuring a large amount of water samples in the water production system is used for monitoring the water quality on line and judging the water quality condition of inlet and outlet water of each system in real time. The water quality on-line analyzer is applied, so that the real-time control of the water quality in the whole process can be realized, the energy consumption can be reduced by utilizing the automatic function of the analyzer on the basis of the existing process and management, the stability of the water quality is ensured, and good economic benefit and social benefit are generated. Because of the operation monitoring requirement, each parameter can be sampled and measured (such as ph and conductance) in each system, each measuring point needs to be correspondingly provided with an online instrument measuring instrument, but because the types and the number of the analyzing instruments are various, the electrodes, internal accessories and the like of the analyzing instruments are all consumables, the daily maintenance workload is large, spare parts are expensive, and the maintenance cost is high.

In a water system, a plurality of online meters are usually installed on each set of equipment to measure water quality related data of an inlet, an outlet and a middle section, but in the actual water production process, because the system runs stably, the change of the water quality cannot change greatly in a short time, the real-time requirement of the data of a water sample is not very high, and a plurality of sets of equipment are usually used alternately in the water production system, one or more sets of online meters are always idle under the condition that the whole equipment runs to produce water, and the idle equipment also needs to be maintained, so that unnecessary workload of maintenance personnel is increased.

The utility model has the following contents:

the utility model aims at providing an online appearance water switches measuring device in order to compensate prior art not enough.

The above purpose is realized by the following technical scheme:

an online sample water switching measuring device comprises a cabinet body, wherein a plurality of input pipes are fixed on the lower layer in the cabinet body, the input pipes are collected to an output pipeline, and the output pipeline is communicated to an online measuring instrument;

each input pipe is provided with a water diversion tee joint, and one output of the water diversion tee joint is communicated with a sewage discharge pipe.

The online sample water switches measuring device, the cabinet of the cabinet body in the upper strata install PLC, PLC with online measuring instrument electricity connect.

Has the advantages that:

1. the utility model discloses concentrate the sampling with adjacent system or the close sample measurement station of quality of water, the device has a sample water delivery outlet and a plurality of drain, switches output water sample to on-line measuring device all the way in all sample water of concentrating the sampling, and surplus sample pipeline switches to the drain and carries out the blowdown. And after the set measurement time, switching to the next water sample for output measurement, and switching the current water sample to a sewage pipeline for sewage disposal to realize the function of measuring a plurality of measuring points by one set of online instrument.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. a touch screen; 2. a PLC; 3. the upper layer in the cabinet; 4. a lower layer in the cabinet; 5. an online measuring instrument; 6. an output pipeline; 7. a blow-off pipe; 8. a water diversion tee joint; 9. an input tube.

The specific implementation mode is as follows:

example 1:

as shown in fig. 1, the device comprises a cabinet body, wherein a plurality of input pipes 9 are fixed on a lower layer 4 in the cabinet body, a PLC2 and a touch screen 1 are fixed on an upper layer in the cabinet body, an online water sample measuring instrument is electrically connected with the PLC and is used for transmitting measured water sample parameters to the PLC, the plurality of input pipes are collected to one output pipeline 6, and the output pipeline is communicated with a linear measuring instrument 5;

and a water diversion tee joint 8 is arranged on each input pipe, one output of the water diversion tee joint is communicated with a sewage discharge pipe 7, and the water diversion tee joint and the flushing tee joint are all three-way electromagnetic valves.

The sampling device has a sample water input and sewage discharge pipeline and a sample water output pipeline in common thought,

only one water-dividing three-way electromagnetic valve of the four water-dividing three-way electromagnetic valves is in a state of being communicated with a sample water output pipeline in the same time period, and the rest of the four water-dividing three-way electromagnetic valves are in a state of being communicated with a sewage discharge pipeline, so that only one water sample is output in the same time period. After each way water sample measurement is accomplished, this way three solenoid valve switches to sewage pipes, and the three solenoid valve of next way switches to output pipeline, and output water sample washes pipeline and instrument measuring pond, washes and carries out the water sample after finishing and measures, switches to the next way again after accomplishing measurement process and washes, measures, and 1 to 4 water sample circuit switch.
