Abstract
It is simple that the utility model relates to a kind of structure, alarm is sulfuric acid cooler recirculated water pH checkout equipment timely, by sulfuric acid cooler, pH meter, PLC system, warning horn, solenoid valve and detection water circle device are formed, PLC system is provided with threshold setting unit, solenoid valve is arranged on sulfuric acid cooler circulating water outlet and is connected with the signal output part of PLC system with between the pipeline branch road being connected pH meter, detect water circle device by reclaiming pond, recovered water pump, circulating water pool, water circulating pump connects to form successively, pH meter detects water out and connects recovery pond, this sulfuric acid cooler recirculated water pH checkout equipment avoids sour water and flows into other equipment, prevent the corrosion to other e-quipment and pipes, improve reaction velocity and the inspection speed of sulfuric acid cooler fault, improve maintenance efficiency, the pH meter arranged detects water circle device recyclable recirculated water every day about 100 tons, i.e. environmental protection but also create benefit for enterprise.
Description
Technical field
The utility model relates to detecting instrument technical field, specifically sulfuric acid recirculated water pH checkout equipment.
Background technology
In sulphuric acid process, sulfuric acid cooler is in high-temperature concentrated sulfuric acid environment for a long time, once heat exchanger tube leaks, if sulfuric acid cooler heavy corrosion can not will be caused by Timeliness coverage, until damage completely, simultaneously, leakage acid enters circulation and also can corrode other equipment and contaminated environment, pH meter detects the straightforward procedure whether sulfuric acid cooler occur to leak, but recirculated water pH meter detects water technological requirement keeps flow state, in the past just in line enter rainwater trench.So not only cause water waste, also cause quantity of wastewater effluent to increase simultaneously.And once there is acid leakage, can only manually close sulfuric acid cooler valve, with other equipment anti-pollution, but artificial closedown exists not in time and causes the situation of not closing by staff's negligence.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of sulfuric acid cooler recirculated water pH checkout equipment accurately to monitor sulfuric acid recirculating cooling water system and whether leak acid, and pH meter detects Water Sproading and recycles.
The technical solution of the utility model is: a kind of sulfuric acid cooler recirculated water pH checkout equipment, by sulfuric acid cooler, pH meter, PLC system, warning horn, solenoid valve and detection water circle device are formed, sulfuric acid cooler circulating water outlet is connected to cooling tower by pipeline, pipeline branch road connects pH meter, pH meter is connected with the information acquisition end of PLC system, the signal input part of alarm device is connected with the signal output part of PLC system, PLC system is provided with threshold setting unit, solenoid valve is arranged on sulfuric acid cooler circulating water outlet with between the pipeline branch road being connected pH meter, control sulfuric acid cooler recirculated water effluent switch and be connected with the signal output part of PLC system, detect water circle device by reclaiming pond, recovered water pump, circulating water pool, water circulating pump forms, pH meter detects water out and connects recovery pond, collect pH meter and detect water, and be conveyed into circulating water pool by recovered water pump, by water circulating pump, water is being squeezed into sulfuric acid cooler entrance, recycle, warning horn is acoustooptic alarm.
Described PLC threshold value assigning unit assigns threshold value is 5, and when pH value is less than 5, closed electromagnetic valve, warning horn is reported to the police.
The advantage that the utility model has and good effect are: it is simple that the utility model provides a kind of structure, alarm is sulfuric acid cooler recirculated water pH checkout equipment timely, the threshold value that the image data of pH meter and PLC system set is contrasted, thus the leakage acid situation of recirculated water is fed back and alarm in time, and by the solenoid valve that PLC system controls, leading pre-service of closing is carried out to circulating water pipeline, avoid sour water and flow into other equipment, prevent the corrosion to other e-quipment and pipes, PLC system exports alarm signal simultaneously, warning horn is reported to the police, improve reaction velocity and the inspection speed of sulfuric acid cooler fault, improve maintenance efficiency, the pH meter arranged detects water circle device recyclable recirculated water every day about 100 tons, i.e. environmental protection but also create benefit for enterprise.
