Figure；
Fig. 2 is Fig. 1 right view.
Embodiment
The utility model is further described with reference to Figure of description.
Embodiment 1
The present embodiment provide it is a kind of utilize heat transferring medium indirect heat exchange coal oven dithio-gas heat exchanger, including shell, middle case,
Inner casing, conduction oil interlayer and conduction oil, heat exchanger, oil storage tank and liquid level gauge；Inner casing and middle case after being welded to connect by forming
Conduction oil interlayer, fills conduction oil in it, and conduction oil is connected by heat-conducting oil pipes with outside conduction oil oil storage tank, conduction oil storage
Oil tank connects liquid level gauge.There is air blanketing between middle case and shell.Heat exchanger is fixed by welding on middle case.
Described heat exchanger is placed in conduction oil interlayer, and heat transferring medium absorbs waste by heat exchanger wall, conduction oil, inner casing
Heat in coal gas.
Concrete structure using heat transferring medium indirect heat exchange coal oven dithio-gas heat exchanger by shell 2, air as shown in figure 1, pressed from both sides
Layer 6, middle case 7, conduction oil interlayer+conduction oil 8, heat exchanger 9, inner casing 10, oil storage tank 13, liquid level gauge 5 and 12 and flange 1
With 2 compositions.Inner casing 10 and middle case 7 are by being welded to connect, it is ensured that weld seam is not revealed, and inner casing 10 and middle case 7 are directly constituted and led
Conduction oil 8 is filled in deep fat interlayer 8, conduction oil interlayer, conduction oil interlayer 8 is connected by heat-conducting oil pipes 14 with oil storage tank 13；Storage
The bottom of oil tank 13 is installed by liquid level gauge 12；The heat-transfer surface of heat exchanger 9 is directly contacted with conduction oil；Heat in raw coke oven gas passes through inwall
10 pass to conduction oil 8, the heat transferring medium that conduction oil 8 is transferred heat in heat exchanger 9 by heat conduction and free convection.
Liquid level gauge 1cm or so is higher by when heat conduction oil level is initial in oil storage tank 13, during normal work, due to conduction oil 8 by
Thermal expansion, the liquid level that liquid level gauge 12 is shown can be increased slightly.
Heat transferring medium enters heat exchanger 9 by heat transferring medium import/export, and heat exchanger inlet and outlet is welded on middle case 7, changed
Thermal medium has certain gap, kept away by heat exchanger wall and conduction oil indirect heat exchange between the inlet/outlet pipe of heat exchanger 9 and shell aperture
Exempt from the shear stress occurred when thermal expansion is inconsistent.
Air blanketing 6 is stained with thermal insulation medium close to shell side, the seam that there is 2~8mm between thermal insulation medium and middle case 7
Gap, while the bottom of air blanketing 6 is left a blank, it is ensured that when leaking, conduction oil smoothly can flow to air folder along the wall of middle case 7
6 bottom of layer, liquid level gauge 5 can monitor liquid level change in time.
When there is 10 corrosion leakage of inner casing, conduction oil 8 can be flowed into raw coke oven gas side, and now the reading of liquid level gauge 12 can drop
It is low, now monitoring system alarming.
When occurring 8 weld leakage of conduction oil interlayer, the meeting air inlet interlayer of conduction oil 8, the reading of liquid level gauge 12 can be reduced,
The reading of liquid level gauge 5 can be slowly increased from 0, now monitoring system alarming.
When heat transferring medium is leaked in heat exchanger 9, according to gas heat exchange medium, now the pressure of oil storage tank 13 can increase；
According to liquid heat transfer medium, the reading of liquid level gauge 12 can continue to increase, now monitoring system alarming.
When the increase of the reading of liquid level gauge 5, and the reading of liquid level gauge 12 is when being basically unchanged, it is possible to determine that the now He of conduction oil interlayer 8
Heat exchanger is leaked.
Because heat transferring medium is exchanged heat by the wall of heat exchanger 9,10 3 layers of thermal resistance of conduction oil 8 and inner casing, it can pass through
Fin, wing pin are welded in the wall of heat exchanger 9, inner casing 10 realizes enhanced heat exchange close to modes such as conduction oil side welding fin, wing pins.
Simultaneously because thermal resistance increase, causes that the raw coke oven gas side wall surface temperature of inner casing 10 is higher, the wall of inner casing 10 is difficult coking.
Because raw coke oven gas has aggressive, thus inner casing 10 by raw coke oven gas from by spraying high temperature anticorrosive paint come reality
The anticorrosion of existing inner casing.
