Description
Technical field
The present invention relates to a kind of flat heating device, in particular, is related to uniform heating and the temperature of a kind of massive plate
Control device.
Background technology
Third generation nuclear reactor employs advanced Passive containment cooling system (PCCS), i.e., in design basis accident
(DBA) after occurring, by the cooling water of the storage tank offer at the top of containment, flow out under gravity, pass through multistage cofferdam pair
Current are evenly distributed, and moisture film covering is formed in containment outer surface.The heat disengaged in accident is in steel safety shell and leads
Exchanged heat in the circular passage of flowing plate composition by water film evaporation, heat convection, the Yi Jian of moisture film sensible heat transfer, air and moisture film
The forms such as full shell itself radiation heat transfer export to outside, so as to ensure that containment internal temperature and pressure are less than in the state of accident
Limiting design value, it is ensured that containment structure integrality and prevent radioactive substance from leaking.
In order to verify the efficiency and applicability of containment passive cooling system, effective method is using big flat at present
Plate carries out moisture film covering cooling test under different angle, to obtain the effect between reflection moisture film heat and mass and each influence factor
Rule.In test, it is necessary to uniformly be heated to massive plate, that is, ensure massive plate (120mm × 500mm × 20mm) everywhere
Temperature substantially remain in a steady state value, it is traditional the mode such as to heat using heating rod, it is difficult to ensure that being only 20mm to thickness
Massive plate uniformly heated.
The content of the invention
The present invention is directed to above-mentioned deficiency of the prior art, there is provided a kind of massive plate uniformly heats and temperature control device, can
To realize the uniform heating to massive plate, securely and reliably, and the regulation of temperature can be realized.
To reach above-mentioned purpose, the present invention is achieved by the following technical solutions：
A kind of massive plate uniformly uniformly arrange some heating copper tubes by heating and temperature control device, the massive plate back side, it is described plus
In the hot copper pipe some semi-circular grooves that slugging opens up at the massive plate back side respectively, conduction oil is flowed through in the heating copper tube, and
The conduction oil flowed through in every heating copper tube is all equal in the temperature of heating copper tube entrance, the heating in adjacent two heating copper tubes
Oil phase is to flowing, and the heating oil in every heating copper tube all only returns to heat transfer oil heater after a heating copper tube,
So as to reduce heating oil temperature drop, improve and heat oily heat transfer efficiency.
The conduction oil flowed through in the every heating copper tube is flowed out from heat transfer oil heater through header box, is then returned again
Return after another header box and flow back to heat transfer oil heater through oil pump, so that every heating tube inlet temperature is all equal, and connect
Nearly heat-conducting oil heating heater outlet temperature.
Heating copper tube slugging by way of silver brazing connects enters in semi-circular groove, and ensures having between cell wall necessarily
Effective contact area.
Technical solution of the present invention, the high-density arrangement welded of being slotted by heating copper tube at the massive plate back side, the friendship of oil circuit
The setting of flow design and heat transfer oil heater to oil temperature is pitched, not only realizes the uniform heating to thin massive plate, can also be right
Plate temperature is controlled and adjusted.

Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out real premised on technical solution of the present invention
Apply, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following embodiments.
Shown in Fig. 1~Fig. 5, device provided by the present invention mainly includes two parts, the design and oil line pipe of heating tube
Design.
As shown in figure 1, in the embodiment of the present invention, in order to ensure the uniform heating of massive plate 1, high in 5m, 1.2m is wide, 20mm
Uniformly arranged 250 external diameter 10mm at the thick steel plate back side, internal diameter 7mm, long 1.2m heating copper tube 2, adjacent two tube hubs line
Distance 20mm.The back side of massive plate 1 opens up the semi-circular groove 3 that diameter is about 11mm, and heating copper tube 2 is buried by way of silver brazing connects
It is solded into groove and ensures 80% effective contact area.
As shown in Fig. 2 the conduction oil in 250 heating copper tubes 2, is all to be flowed out from heat transfer oil heater 4 through header box, so
After return again to after another header box and flow back to heat transfer oil heater 4 through oil pump, i.e., every heating tube inlet temperature is all equal, and connects
The nearly outlet temperature of heat transfer oil heater 4.In order to ensure the uniform heating to steel plate, the heating oil in adjacent two heating copper tubes 2
Flow in opposite directions.And the heating oil in every heating copper tube all only after a heating copper tube, that is, return conduction oil add
Hot stove, so as to reduce heating oil temperature drop, improve and heat oily heat transfer efficiency.
Heat transfer oil heater can realize the setting and control of oil temperature, and the certain conduction oil of temperature flows through heating copper tube to copper
Pipe is heated, and then steel plate is heated.Realize the control to massive plate temperature indirectly by the regulation can of oil temperature
And regulation.
Above by heating copper tube the massive plate back side fluting welding high-density arrangement, the cross-flow design of oil circuit and
Setting of the heating furnace to oil temperature, not only realize the uniform heating to thin massive plate, plate temperature can also be controlled and
