Technical Field

The utility model relates to an milipore filter leaks monitoring device, and specifically speaking is one kind can be automatically whether leak the milipore filter and examine, makes the milipore filter leak monitoring device that the milipore filter operation is safer.

Background

If leakage is not found in time during the operation of the ultrafiltration membrane, a large amount of sludge or impurities leak to the ultrafiltration water production pool and the subsequent process section, so that a sewage plant or a factory stops production emergently and cleans the pool. This process will consume a large amount of manpower and material resources and present safety, environmental protection and quality control risks. During the operation of the ultrafiltration membrane, the membrane is easy to damage due to the friction with impurities such as silt in water or the reason of chemical cleaning, so that pollutants are leaked, and the quality of produced water of the ultrafiltration membrane serving as a secondary treatment device in water treatment not only influences whether the produced water of a subsequent advanced treatment process reaches the standard, but also influences whether subsequent advanced treatment equipment is damaged. However, the damage and leakage of the ultrafiltration membrane in the water treatment process are not monitored in the industry at present, mainly because most process designers do not know the damage or leakage frequency of the ultrafiltration membrane and do not have good solutions.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above-mentioned problem that prior art exists, an automatic monitoring device of milipore filter is provided, the device is through online control ultrafiltration product water quality of water, judge whether the milipore filter leaks, automatic management and control unusual ultrafiltration system and alarm processing, the milipore filter is because of its efficient solid-liquid separation effect, become the core technology among pure water manufacturing and the sewage treatment, especially in filtration liquid treatment, because of it takes up an area of for a short time, the separation effect is good, more have the incomparable advantage of sedimentation tank among the traditional sewage treatment technology, receive the industry and use widely.

The technical solution of the utility model is at the intake pump, the milipore filter, the tank, the drain pump, the deep processing system, turbidity appearance, the PLC controller, well accuse computer, the water intaking valve, produce the water valve, on the basis of drain valve, characteristics are that water intaking valve and intake pump are connected with the end of intaking of milipore filter after establishing ties in proper order through the pipeline, install on the pipeline of being connected between the drainage end of milipore filter and the tank water inlet and produce the water valve, the drainage end of producing the water valve is provided with turbidity appearance, install drain valve and drain pump on the pipeline of being connected between the outlet of tank and the water inlet of deep processing system in proper order.

Water intaking valve, intake pump, product water valve, turbidity appearance, drain valve, the respective signal end of drain pump all be connected with the corresponding signal processing end of PLC controller, the PLC controller shows that signal output part is connected with the demonstration status signal receiving terminal of well accuse computer.

PLC controller and water intaking valve, the intake pump, produce the water valve, the drain valve, the signal processing end that drain pump signal end is connected is closing signal output part, the water intaking valve, the intake pump, produce the water valve, the drain valve, the signal end of drain pump is the closing signal receiving terminal, the closing signal output part of PLC controller is respectively to the water intaking valve, the intake pump, produce the water valve, the drain valve, triggering signal is closed in the conveying of the closing signal receiving terminal of drain pump, the signal processing end that the PLC controller is connected with the turbidity appearance is the monitoring signal receiving terminal, the signal end of turbidity appearance is the monitoring state output, the monitoring state output of turbidity appearance transmits monitoring range value signal to the monitoring signal receiving terminal of PLC controller.

The utility model discloses a theory of operation is through setting for online turbidity meter monitoring range, and when the measured data was higher than the setting value, its signal transmission to PLC sent closing command through PLC to water intaking valve, intake pump, product water valve, drain valve and drain pump, made the milipore filter stop work of leaking and made the sewage of leaking not get into next process to make the anomalous accident stamp out in the sprouting stage. Meanwhile, the PLC transmits the abnormal event to the central control computer through an alarm signal, and the operator on duty can handle the abnormal event on site at the first time, so that further deterioration of the accident is avoided.

The utility model has the advantages that the provided ultrafiltration membrane monitoring device can automatically discriminate whether the ultrafiltration membrane leaks, so that the ultrafiltration membrane can run more safely; and this device can be to unusual automatic control to can manage and control in the very first time when making the milipore filter leak, when avoiding safety, environmental protection and article accuse accident in the operation, promote water treatment system's stability, reduce manual operation, reduce system equipment maintenance frequency, thereby practice thrift the cost.
