Equipment derived by a kind of new Type Coke Oven raw gas, it is characterized in that, comprise: steel frame, upcast, upcast bridge tube, the brick gas passage surrounded by fireclay brick, effuser bridge tube and effuser, described brick gas passage and effuser are all installed on steel frame, described brick gas passage is connected with upcast by upcast bridge tube, described effuser is connected with upcast by effuser bridge tube, upcast bridge tube flap valve is provided with in described upcast bridge tube, effuser bridge tube water seal flap valve is provided with in described effuser bridge tube, described effuser top is provided with can to the ammoniacal liquor shower nozzle of the inner sprinkle ammoniacal liquor of effuser.
On technique scheme basis, described brick gas passage periphery is provided with insulation thermal insulation layer.
On technique scheme basis, described upcast top has the upcast clean-out opening for cleaning upcast inner chamber, described upcast bridge tube having the bridge tube clean-out opening for cleaning upcast bridge tube inner chamber, described brick gas passage having the brick gas passage clean-out opening for cleaning brick gas passage inner chamber.
On technique scheme basis, described effuser bridge tube is provided with aerobic water shower nozzle, described aerobic water shower nozzle is positioned at the top of effuser bridge tube water seal flap valve.
The utility model tool has the following advantages: can intercept raw gas high temperature sensible heat, the superheated vapour of production high-quality generates electricity, and reclaims raw gas reaches synergy consumption reduction object to UTILIZATION OF VESIDUAL HEAT IN; There is the function that raw gas is derived; Brick gas line has adiabatic heat-insulation function; Effuser has washing heat exchange to raw gas, removes the function of the coal-tar middle oil and impurity of raw gas.
Accompanying drawing explanation
Fig. 1: cross-sectional view of the present utility model;
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, equipment derived by a kind of new Type Coke Oven raw gas of the present embodiment, it is characterized in that, comprise: steel frame 5, upcast 2, upcast bridge tube 9, the brick gas passage 3 surrounded by fireclay brick 13, effuser bridge tube 15 and effuser 4, upcast 2 is cylinder, for heat resisting brick builds lining by laying bricks or stones in cylindrical shell, outside cylindrical shell is that cast steel or cast iron quality are formed, its root 7 is installed on oven top of coke oven 1, described brick gas passage 3 and effuser 4 are all installed on steel frame 5, described brick gas passage 3 is connected with upcast 2 by upcast bridge tube 9, described effuser 4 is connected with upcast 2 by effuser bridge tube 15, upcast bridge tube flap valve 10 is provided with in described upcast bridge tube 9, upcast bridge tube flap valve 10 material can be cast iron, be provided with effuser bridge tube water seal flap valve 17 in described effuser bridge tube 15, the keying of effuser bridge tube water seal flap valve 17 is controlled by water seal flap valve handle 18, and described effuser 4 top is provided with can to the ammoniacal liquor shower nozzle 19 of the inner sprinkle ammoniacal liquor of effuser 4.
Preferably, described brick gas passage 3 periphery is provided with insulation thermal insulation layer 14, its objective is and prevents raw gas excessive drop temperature in brick gas passage 3.
Preferably, described upcast 2 top has the upcast clean-out opening 8 for cleaning upcast 2 inner chamber, described upcast bridge tube 9 having the bridge tube clean-out opening 11 for cleaning upcast bridge tube 9 inner chamber, described brick gas passage 3 having the brick gas passage clean-out opening 12 for cleaning brick gas passage 3 inner chamber.
Further, described effuser bridge tube 15 is provided with aerobic water shower nozzle 16, described aerobic water shower nozzle 16 is positioned at the top of effuser bridge tube water seal flap valve 17.
When intercepting crude-gas sensible heat and producing superheated vapour, open the upcast bridge tube flap valve 10 closure set tracheae bridge tube water seal flap valve 17 in upcast bridge tube 9, now raw gas enters brick gas passage through upcast, upcast bridge tube 9, enters residual heat boiler for exchanging heat along brick gas passage.Brick gas passage guarantees that raw gas temperature reduces cooling before entering waste heat boiler, makes it keep higher temperature (to be not less than 650 ° c), in order that the superheated vapour of production higher quality.
When waste heat boiler need stop production to overhaul or break down need stop production time, effuser bridge tube water seal flap valve 17 can be opened, close upcast bridge tube flap valve 10, after now raw gas enters lower the temperature with ammoniacal liquor heat exchange in effuser 4 along effuser bridge tube 15, raw gas enters cleaning shop through air water separator.
The new Type Coke Oven raw gas derivation equipment of the application both can reclaim crude-gas sensible heat production superheated vapour and go generating, did not affect again the normal production operation of coke oven, had reclaimed crude-gas sensible heat, reduced gas consumption.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
