The present invention seeks to, a kind of portable sampling analysis device is provided, by the enforcement to this programme system, without the need to being connected between water and steam sampling by unified for all sampling spots, the sample water simultaneously adopted has more representativeness, can carry out sampling analysis to sampling spot any in factory building, and equipment set adopts miniaturization and light-weight design, can power to chemical instruments voluntarily, not by the neighbouring restriction with or without access power supply simultaneously.
Portable sampling analysis device, connect successively high temperature valve, high pressure filter, cooling device, reliever, tensimeter is comprised to mechanical type overtemperature shut-off valve from sample water inlet, mechanical type overtemperature shut-off valve two-way pipeline in parallel, one tunnel is current stabilization blowdown valve, current stabilization blowdown valve pipeline is provided with thermometer, exports discharging container to, and another road pipeline in parallel is to measuring channel, measuring channel distinguishes meter in series valve, flowmeter and exchange column successively, and exchange column is Series detectors instrument again; Measuring instrument exports also to discharging container.
The relevant apparatus such as the chemical instruments needed for monitoring, cooling and decompression are integrated in moveable car body, realization can at any time, paroxysmal sampling observation or carry out steam sample Real-Time Monitoring in the mode that routine is patrolled and examined, the connection of sample water all adopts rapid-acting coupling, abandon complicated Joining Technology, make that whole sample analysis process is simple, the time is short, the sample water simultaneously obtained more truly can reflect the true water quality parameter of sampled point.
The present invention adopts high-effect cooling and pressure regulating equipment, due to the temperature of each point in Power Plant Water Vapor circulating line and pressure parameter each different, while wanting to meet various temperature and pressure simultaneously, make package unit volume energy relatively little again, be convenient to move in whole factory building, this device adopt high-effect cooling (fan etc. force cooling, air cooling, without the need to chilled water) and pressure regulating equipment, by the water cooling of High Temperature High Pressure sample and the pressure be decompressed to needed for applicable instrumental analysis and hand sampling and temperature.
Sample overtemperature and overpressure protection, the present invention considers the personal injury that superhigh temperature superelevation pressure-like water may cause operating personnel, mechanical type temperature Shuttoff Valve and current stabilization blowdown valve is adopted to ensure the personal safety of operator, mechanical type temperature shut-off valve without the need to artificially interfering, when temperature is higher than the sample water that automatically switched in 2 seconds when 49 DEG C; Current stabilization blowdown valve carries out pressure release when sample water superpressure on the one hand, ensures that the pressure of sample water is steady simultaneously.
Still can use under the emergency circumstance, portable sampling analysis device carries ups power, does not nearby have also to carry out normal power supply to chemical instruments during power supply.
Beneficial effect of the present invention: the basis that the present invention be directed to the centralized sampling that current nuclear power plant and thermal power plant's routine adopt is researched and developed, and this device is applicable to mobile sampling, assault sampling, can in factory building arbitrarily sampling point sample water carry out sampling analysis.There is high maneuverability, the feature such as the convenient and sample of sampling has more representativeness, sampling analysis is convenient; High-effect cooling and pressure regulating equipment, sample water overtemperature and overpressure protection can ensure the safety in use.Portable sampling analysis device of the present invention, portable sampling analysis device is innovation research and development on the basis for the conventional centralized sampling adopted of current nuclear power plant and thermal power plant, this device is applicable to mobile sampling, assault sampling, can carry out sampling analysis to sampling point sample water any in factory building.The relevant apparatus such as the chemical instruments needed for monitoring, cooling and decompression are integrated in moveable car body, realization can at any time, paroxysmal sampling observation or carry out steam sample Real-Time Monitoring in the mode that routine is patrolled and examined, the connection of sample water all adopts rapid-acting coupling, abandon complicated Joining Technology, make that whole sample analysis process is simple, the time is short, the sample water simultaneously obtained more truly can reflect the true water quality parameter of sampled point.Still can use under the emergency circumstance, portable sampling analysis device carries ups power, does not nearby have also to carry out normal power supply to measuring instrument (being generally chemical instruments) during power supply.
