Embodiment
The utility model is further described with reference to Figure of description.
Embodiment 1
The present embodiment provides a kind of raw coke over gas riser heat exchanger, it by heat exchanger inner casing, intraformational bed, middle case,
Heat-insulation layer, shell, heat exchanger tube, airway tube and heat exchanger are vertically connected with flange composition.Heat exchanger by be vertically connected with flange with
Coke oven crossover main is connected with carbonization chamber outlet.Inner casing and middle case ensure that its sealing is excellent by being welded to connect, during work
Gas leakage does not occur when closing for electric control valve.It is intraformational bed between inner casing and middle case, filled solid heat conduction in intraformational bed
Medium, heat-conducting medium account for more than half of intraformational bed volume, according to the thermal expansivity of heat-conducting medium, ensure that heat exchanger tube can during work
Fully to be contacted with heat-conducting medium, i.e., heat exchanger tube is wholly embedded into heat-conducting medium.Raw coke oven gas heat by inner casing, heat-conducting medium and
Heat exchanger tube passes to the cooling medium in heat exchanger tube.Heat exchanger tube and airway tube are welded on middle case, and airway tube passes through on shell
Aperture pass, pressure gauge, air accumulator and electric control valve are installed on the airway tube of outside, because airway tube connects intraformational bed,
Therefore air guide overpressure is inner clip stressor layer, and during normal temperature, intraformational bed gauge pressure is 0, and volume of gas storage tank is empty with intraformational bed top
Between (do not taken up space by heat-conducting medium) substantially quite, consider 200-400 degrees Celsius of heat-conducting medium design work temperature, thus
In process of coking, intraformational bed operating pressure is less than 0.25MPa, i.e. pressure gauge gauge pressure is less than 0.15MPa.
When heat exchanger inner casing occur corrosion failure, or intraformational bed weld seam it is cracking when, gage pressure can be down to
Normal pressure；When in heat exchanger heat exchanger tube be damaged leakage when, the pressure of pressure gauge can be slowly increased, finally with exchange heat overpressure
It is equal；When airway pressure is higher than 0.25MPa, i.e., when pressure gauge gauge pressure is more than 0.15MPa, electric control valve is opened, works as gauge pressure
When being down to 0.15MPa, electric control valve is closed, if now pressure continues to raise, you can be determined as that heat exchanger tube leaks.
In the above-mentioned technical solutions, described shell is fixed on heat exchangers by multi-disc riveting method, can be in not blowing out
Shell is opened under state, heat exchanging device middle case, inner casing and weld seam are checked.
Concrete structure as shown in figure 1, raw coke over gas riser heat exchanger 1 by heat exchanger lower flange 1.1, upper flange
1.2nd, inner casing 1.3, intraformational bed 1.4, cooling medium 1.5, heat exchanger tube 1.6, middle case 1.7, heat-insulation layer 1.8 and shell 1.9 are formed.
Heat exchanger lower flange 1.1 is connected with carbonization chamber outlet, and heat exchanger upper flange 1.2 is connected with coke oven crossover main, passes through heat exchanger
Lower flange 1.1 and heat exchanger upper flange 1.2 realize the fixation of heat exchanger.High temperature raw coke oven gas exports from carbonization chamber enters heat exchange
Device 1, heat is passed into cooling medium by inner casing 1.3, heat-conducting medium 1.5, heat conducting pipe 1.6, realizes raw coke oven gas waste heat
Recovery.
Downstream heat transfer mode is used as cooling medium, recommendation according to water, cooling medium is entered by cooling medium inlet 2
Heat exchanger tube 1.6, pass through the outflow of cooling medium outlet 4 after heat exchange.It is cooling medium according to gas, recommendation uses countercurrent flow side
Formula is heated, and cooling medium inlet and outlet 2,4 are exchanged, and are repeated no more.The present embodiment selects water as cooling medium.
Because the heat of raw coke oven gas first passes to inner casing 1, heat-conducting medium 1.5 is passed to by heat conduction, heat-conducting medium 1.5 is again
Heat exchanger tube 1.6 is passed to, three layers of thermal resistance between raw coke oven gas to cooling medium be present, therefore in order to reduce thermal resistance, can pass through
In inner casing 1.1 by the side of heat-conducting medium 1.5 welding fin, wing pin mode augmentation of heat transfer, wing can also be equally welded on heat exchanger tube
Piece, wing pin mode enhanced heat exchange, the heat transfer coefficient of raw coke oven gas side installation disturbing flow device increase raw coke oven gas side in heat exchanger 1, by
In overall thermal resistance increase, with heat transferring medium directly compared with the water leg that inner casing 1 contacts, the temperature dimensionality reduction of inner casing 1 is held compared with high workload
Temperature, so as to the coking for avoiding inner casing from avoiding.
The pressure in normal temperature of intraformational bed 1.4 is also normal pressure, and the blank volume of the volume of air accumulator 5.2 and intraformational bed 1.4 (removes
The volume that heat transferring medium accounts for) quite, air accumulator 5.2 plays certain cushioning effect, avoids intraformational bed 1.4 in work process
When interior temperature raises suddenly, pressure increases suddenly, ensures the trouble free service of intraformational bed.Because intraformational bed has preferably sealing
Property, when heat exchanger is started working, intraformational bed temperature is progressively warming up to 200~400 DEG C of operating temperature, and inner clip stressor layer is also progressively
Rise, but highest not over 0.25MPa, i.e., the gage pressure readings of pressure gauge 5.1 are not over 0.15MPa.During normal work, keep away
Exempt from intraformational bed simultaneously by pressure and temperature effect, when the reading of pressure gauge 5.1 is more than 0.15MPa, open electric control valve 5.3；
When the reading of pressure gauge 5.1 is down to 0.15MPa, electric control valve 5.3 is closed.
Heat exchanger working condition judges：
In process of coking, the reading of pressure gauge 5.1 remains unchanged, and now may determine that intraformational bed 1.4 leaks, should and
When take measures, shut-off inlet and outlet water valve, leak check position, make maintenance or change.
In process of coking, when the reading of pressure gauge 5.1 is more than 0.15MPa, electric control valve 5.3, the reading of pressure gauge 5.1 are opened
When being down to 0.1MPa, electric control valve 5.3 is closed., can if the reading of pressure gauge 5.1 rises to 0.15MPa again after work a period of time
To judge that cooling medium is revealed, inlet and outlet water valve should be now turned off rapidly, heat exchanger replacing is carried out when blowing out.
Heat conducting pipe 1.6 is arranged in heat-conducting medium using serpentine manner in this example, can also use straight tube, helix tube etc.
Mode, as long as ensureing sealing of the cooling medium in heat exchanger tube.
Embodiment 2
The present embodiment and the difference of embodiment 1 are：The two edges up and down of the middle case of the present embodiment not with inner casing
Connecting, the two edges up and down of the middle case in the present embodiment are connected with upper and lower flange seal, also, in order to ensure to measure intraformational bed
In pressure it is accurate, it is necessary to which the lower edges of inner casing are also connected and sealed with upper lower flange.
More than, preferred embodiment only of the present utility model, but the scope of protection of the utility model is not limited thereto, and is appointed
What those familiar with the art the change that can readily occur in or replaces in the technical scope that the utility model discloses
Change, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with claim
The protection domain defined is defined.
