Description
Technical Field
The utility model relates to the technical field of coke oven tops, in particular to a coke oven top sealing structure and a coke oven.
Background
After the coke guide opens the furnace door, a large amount of smoke flows out of the carbonization chamber, and most of the smoke can escape upwards due to the high-temperature smoke. Traditional furnace top flue gas collection structure adopts structures such as rubber plate or various steel sheet, and it is along to act as the seal, and sealed effect is limited. And because the sealing edge and the furnace door need to relatively move, the sealing edge is difficult to control a gap between the sealing edge and the furnace door, and is often worn seriously, so that the sealing is invalid and smoke dust overflows.

The utility model mainly solves the technical problems of poor sealing effect, poor sealing effect and the like of a furnace top sealing structure in the prior art, and provides a coke oven top sealing structure and a coke oven, which can realize better sealing effect and reduce abrasion to a furnace door.
The utility model provides a coke oven top sealing structure, which comprises a water seal groove and an oven top smoke suction cover;
the water seal tank is arranged on the side wall of the furnace door; the water seal tank is used for containing water;
the furnace top smoke-absorbing cover is arranged at the top of the furnace door; a water tank baffle is arranged at one side of the furnace top smoke suction cover; the other end of the water tank partition plate stretches into water in the water seal tank and is not contacted with the bottom surface of the water seal tank.
Further, one end of the water seal tank is provided with a water drain pipe; the other end of the water drain pipe is provided with a water tank; and an electric valve is arranged at one end of the water discharge pipe, which is close to the water tank.
Further, one end of the water seal tank is provided with a liquid level sensor.
Further, the furnace door wall is provided with a side protection cover; the side protection cover is positioned below the furnace top smoke suction cover.
Furthermore, an anti-corrosion layer is arranged on the surface of the water tank partition plate.
Further, a coke oven comprising the coke oven roof sealing structure of any one of the above.
Compared with the prior art, the sealing structure of the coke oven top provided by the utility model adopts water sealing, and can realize complete sealing of the gap at the top of the oven door, thereby reducing leakage of the flue gas of the oven head, effectively reducing the temperature of the top plate of the oven door and prolonging the service time of the oven door.

FIG. 2 is a side view of the oven roof sealing arrangement of the present utility model;
reference numerals: 1. a water tank; 2. an electric valve; 3. a water drain pipe; 4. a liquid level sensor; 5. a water seal groove; 6. a burner smoke-absorbing cover; 7. a water tank middle partition plate; 8. water; 9. a furnace door; 10. furnace end smoke; 11. and a side shield.
Detailed Description
In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects achieved clearer, the utility model is further described in detail below with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present utility model are shown in the accompanying drawings.
Example 1
As shown in fig. 1, the coke oven top sealing structure provided by the embodiment of the utility model comprises: the water seal groove 5 and the furnace top smoke-absorbing cover 6 are arranged on the side wall of the furnace door 9; the water seal tank 5 is internally used for containing water 8; the furnace top smoke-absorbing cover 6 is arranged at the top of the furnace door 9, and the water seal groove 5 is arranged at a gap between the furnace door 9 and the furnace top smoke-absorbing cover 6;
a water tank baffle 7 is arranged on one side of the furnace top smoke suction hood 6; the other end of the water tank baffle 7 stretches into water 8 in the water seal tank 5, and the water tank baffle 7 is not contacted with the bottom surface of the water seal tank 5, so that a water seal structure is formed. The surface of the water tank partition plate 7 is provided with an anti-corrosion layer, so that the service life of the water tank partition plate 7 is prolonged.
One end of the water seal tank 5 is provided with a water drain pipe 3; the other end of the water drain pipe 3 is provided with a water tank 1; an electric valve 2 is arranged at one end of the water drain pipe 3, which is close to the water tank 1. One end of the water seal tank 5 is provided with a liquid level sensor 4. When the water level in the water seal tank 5 is insufficient, the liquid level sensor 4 detects that the water level is insufficient, the control system controls the electric valve 2 to be opened, water flows out of the water tank 1 and flows into the water seal tank 5 through the water drain pipe 3, and when the water level in the water seal tank 5 meets the requirement, the liquid level sensor 4 sends out a signal, the electric valve 2 is closed, and water supplementing is completed.
Example 2
A coke oven comprising the coke oven roof sealing structure of embodiment 1.
The utility model relates to a coke oven top sealing structure working principle: when the furnace door is opened, furnace end smoke 10 in the furnace is gushed out through the furnace door 9, the furnace end smoke 10 is sucked away by the furnace end smoke suction cover 6, when part of the furnace end smoke 10 wants to overflow from the front gap, the furnace end smoke 10 encounters the water seal 8, and the furnace end smoke 10 is blocked to return. When the water level in the water seal tank 5 is insufficient, the liquid level sensor 4 detects that the water level is insufficient, the control system controls the electric valve 2 to be opened, water flows out of the water tank 1 and flows into the water seal tank 5 through the water drain pipe 3, and when the water level in the water seal tank 5 meets the requirement, the liquid level sensor 4 sends out a signal, the electric valve 2 is closed, and water supplementing is completed.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments is modified or some or all of the technical features are replaced equivalently, so that the essence of the corresponding technical scheme does not deviate from the scope of the technical scheme of the embodiments of the present utility model.
