Embodiment
The technological means realized to make the utility model, technical characteristic, utility model object and technique effect are easy to understand, and below in conjunction with concrete diagram, set forth the utility model further.
Be illustrated in figure 1 the voltage stabilizer of a kind of integral reactor of the present utility model, comprise a downward opening steel vessel 1.Container 1 in the utility model is communicated with bottom reactor coolant 10 by flange or welding.
The utility model also comprises a demarcation strip 2 for being separated, for the formation of an airtight voltage stabilizing space with the external world by container 1; Demarcation strip 2 in the utility model is thermal insulation board, thus forms effective entity with bottom reactor coolant 10 and heat is separated.
Airtight voltage stabilizing space is divided into two parts, and its middle and upper part is vapour chamber 8, is water chamber 9 in the bottom of vapour chamber 8; Offering multiple mounting hole at the sidewall of described container 1, for running through, many electrical heating elements 3 being installed; Electrical heating elements 3 is immersed in the water chamber 9 of described container 1.
Demarcation strip 2 is provided with first kind Surge line piping 4 and Equations of The Second Kind Surge line piping 6; Wherein the mouth of pipe of first kind Surge line piping 4 down, and this first kind Surge line piping 4 is communicated with described water chamber 9 and bottom reactor coolant 10, and on first kind Surge line piping 4, be provided with an one way stop peturn valve 5.
The mouth of pipe of Equations of The Second Kind Surge line piping 6, is communicated with bottom reactor coolant 10 and vapour chamber 8 upward.The height of Equations of The Second Kind Surge line piping 6 of the present utility model is greater than the height of described water chamber 9, and is provided with a pressure-release valve at the top of this Equations of The Second Kind Surge line piping 6, and the unlatching of this pressure-release valve needs the pressure reduction exceeding threshold value, to prevent its startup too frequent.
For ease of understanding the technical solution of the utility model, the following is elaboration the utility model scheme concrete further.The utility model voltage stabilizer is communicated with bottom reactor coolant 10 by flange or welding manner, and the space on demarcation strip 2 is exactly airtight voltage stabilizing space, and the inside is saturated water and steam.
Water temperature in the water temperature at reactor coolant 10 place, general bottom and airtight voltage stabilizing space differs about 40 DEG C, and therefore, the Thermal Synthetic conductance of demarcation strip 2 is little, and thermal stress is also little.
When the pressure of bottom reactor coolant 10 reduces suddenly, starting the electrical heating elements 3 be immersed in water chamber 9, by heating water chamber 9, making inner boosting.The pressure of voltage stabilizer passes to bottom reactor coolant 10 by first kind Surge line piping 4, makes it boost.
When the pressure of bottom reactor coolant 10 raises suddenly, because first kind Surge line piping 4 is provided with one way stop peturn valve 5, the water therefore in bottom reactor coolant 10 up can only be run by Equations of The Second Kind Surge line piping 6.If the pressure reduction between bottom reactor coolant 10 and vapour chamber 8 is greater than the unlatching threshold value of sprinkler 7, then the water in Equations of The Second Kind Surge line piping 6 then can back down sprinkler 7, sprays to vapour chamber 8.Due to ejection is subcooled water, and be not steam, therefore the pressure of vapour chamber 8 can not obviously raise, and even declines to some extent owing to making the steam-condensation in vapour chamber 8.And bottom reactor coolant 10 is owing to having overflowed part water to airtight voltage stabilizing space, its pressure can decline, until reach new balance between itself and airtight voltage stabilizing space pressure.
From foregoing description, by arranging the Equations of The Second Kind Surge line piping 6 being communicated with vapour chamber 8 and bottom reactor coolant 10, the utility model is that bottom reactor coolant 10 provides very large pressure buffer mechanism.The effect of Equations of The Second Kind Surge line piping 6 is similar to the outside injection spray pipe of traditional voltage stabilizer.
From foregoing description, one way stop peturn valve 5 on first kind Surge line piping 4 plays an important role: if do not arrange one way stop peturn valve 5, then when bottom reactor coolant 10 pressure raises suddenly, water directly enters the water chamber 9 in the utility model by first kind Surge line piping 4, the space of extruding vapour chamber 8, thus the pressure in airtight voltage stabilizing space rises instantaneously, until with the pressure equilibrium of bottom reactor coolant 10.
If the air space of voltage stabilizer is enough large, so in the process, voltage stabilizer pressure increase amplitude can control within scope of design, and in fact some integral reactors are exactly the voltage stabilizer that have employed large space.And the pressure buffer mechanism that the utility model adopts, even if the space of vapour chamber 8 is less, also effectively pressure adjustment can be carried out.
Sprinkler 7 on Equations of The Second Kind Surge line piping 6, carries the function of pressure-release valve, and its unlatching needs the pressure reduction exceeding threshold value, to prevent its startup too frequent.
Equations of The Second Kind Surge line piping 6 is immersed in vapour chamber 8, and its absolute altitude is also an important design parameter.If dried up line is excessively near, so when the water of more bottom reactor coolant 10 is by after upwards Surge line piping 6 enters voltage stabilizer, upwards Surge line piping 6 top by water chamber 9 submergence, thus will lose pressure buffer ability.If dried up line is excessively far away, so after water level is more and more higher, pressure jump being produced close to during spill-over, destroy whole system.
Voltage stabilizer of the present utility model is applicable to integral reactor, and its structure is simple, and function is complete, can not only realize pressure controlling, and can decrease additional conduits setting, meets the requirements such as equipment integration, modularization.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should belong to technology category of the present utility model.
