Power Station Intelligent Intelligent Automatic Sampling System Patent No.: 202020605203.4

12. High and low temperature sample frame    

The boiler water sampling device is used to cool down the boiler water. The sampling device of the boiler water includes: the high temperature rack, the instrument panel, and two parts. Sample water adjustment, use industrial water or saline to take away the work of refueling the cooling frame for cooling racks.

Each parameter of water vapor quality control is based on25℃ is the standard, chemical analysis of the online measuring instrument, and the exactly converted range is0～60℃, so water sample can only be lower than less60° C (National Standard Requirements), boiler water sampling device is to meet the online instrument60Measure within ° C, change the automatic cooling and pressure -lowering equipment of boiler water from high to low temperature, high pressure to low pressure, to ensure that online analysis instruments are continuously, reliable, and securely sampled and analyzed.

 Hand -handled sample discs and online analysis instruments merge the merger to be designed to facilitate maintenance and reduce the installation volume of equipment space. Small sampling device installation在Behind the rear of the overall instrument rack (later referred to as instrument rack), an analysis measurement instrument is installed on the front panel.

 The design of high and low temperature sample rack adopts two combinations of cooling and constant pressure treatment, high temperature take -up point -cooled and sample water cooling, and high -temperature sewage after pre -cooling. Life life of valve. Our unit via temperature rack adopts secondary filtration to prevent blockage and pollution. The high -temperature giants are layered in high and low temperature tabs to facilitate maintenance and treatment. High -temperature and high pressure valves should use products with stable performance. Valve petals and valve seats should be high -temperature -resistant and high -pressure alloy steel. All high -pressure mid -pressure valves are needle -type valves. Coolingrs should choose high -cooling efficiency cooler or high -efficiency cooling down and lowering. Pressor. Under different running pressure and main steam parameters, the sample level level will be adjusted according to different situations to ensure the effect and reduce costs for the owner.

2, Constant temperature control system

The constant temperature device keeps the sample water in25Around ° C, reduce the error caused by temperature compensation. All pipelines, valves, filters and chemical measuring instruments are installed on a base,It is installed in place before the factory, and the on -site water pipe, cooling water pipe and power supply to the instrument need to be connected.

main feature:

● Imported well -known American brand compressor, which is ultra -long and durable.

● Great high -quality joint venture condenser ensures the refrigeration effect.

● Using a unique upper and lower structure, the upper and lower evaporation dishes and sample water pipes, the lower compressor condenser and other refrigeration systems, the layout is reasonable and the area is small

● The warm groove adopts an evaporate dish and sample water pipe intercess mesh layout to ensure that the water -like constant temperature is accurate and fast.

● Automatic temperature monitoring unit; fully automatic hydration function with constant temperature tank
