Description

Coke oven crude gas smoke guide device

Technical Field

The utility model relates to a coke oven correlation technique field specifically is a coke oven raw coke oven gas leads cigarette device.

Background

At present, the top of a coke oven is provided with a smoke guide vehicle, the smoke guide vehicle adopts a smoke guide pipe with two or more inlets and outlets to guide raw coke gas in one coking chamber into a coking chamber close to the final coking stage, and the production process is mature. When the existing smoke guide pipe guides smoke, serious high-temperature deformation can be generated due to open fire or long-time high-temperature smoke, and even welding seams crack and the like can be generated. Even if the smoke guide pipe made of special materials can be improved to a certain extent, the problems cannot be avoided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that the prior coke oven smoke guide pipe has serious high-temperature deformation and is easy to crack.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a coke oven raw coke oven gas leads cigarette device, including leading the cigarette car, elevating system and leading the tobacco pipe, elevating system installs on leading the cigarette car and be used for driving and leads the up-and-down motion of tobacco pipe, it is equipped with two at least entrances and exits to lead the tobacco pipe, and every exit position department all is equipped with the governing valve, the outline line of the cross section of leading the tobacco pipe is the wave line (wave line is the line that a plurality of circular arcs or elliptical arc just receive the tail to meet and form) end to end circular structure that forms, and the pipe wall of leading the tobacco pipe forms a plurality of bar concave parts and bar convex part parallel rather than the axis (bar concave part and bar convex part are exactly because wave cross section outline forms, bar concave part and bar convex part are parallel with the axis, and the non-spiral, the purpose is.

When the smoke guide vehicle is used, the smoke guide vehicle moves to the top of the coke oven, the lifting mechanism is started, the smoke guide pipe is driven to descend to be in butt joint with the carbonization chamber, and smoke guide is started.

The utility model has the advantages that:

the utility model provides a coke oven crude gas smoke guide device, when guiding smoke, the smoke guide tube expands radially and thermally, and the smoke guide tube enlarges properly; after the smoke guide is finished, the smoke guide pipe shrinks and becomes small properly, so that the deformation of the smoke guide pipe is reduced, and the phenomenon of local cracking is avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1 to 3, the coke oven crude gas smoke guide device of the present invention comprises a smoke guide car 1, a lifting mechanism 2 and a smoke guide pipe 3, wherein the lifting mechanism 2 is mounted on the smoke guide car 1 and is used for driving the smoke guide pipe 3 to move up and down to butt the carbonization chamber, and the butt joint with the cylinder can be achieved by using a water tank sealing structure commonly used in the coking field; the lifting mechanism 2 adopts a cylinder, a lead screw and other common lifting mechanisms 2, the smoke guide tube 3 is provided with at least two inlet and outlet 7, the specific arrangement of a plurality of inlet and outlet 7 is determined according to the needs, if the raw gas of one carbonization chamber is guided into another carbonization chamber, only two inlet and outlet 7 are needed to be arranged, if the raw gas of one carbonization chamber is guided into the other two carbonization chambers, three inlet and outlet 7 are needed to be arranged, during the specific design, two inlet and outlet 7 are formed at the two ends of the smoke guide tube 3, and the axial middle part of the smoke guide tube 3 is hermetically connected with a branch tube to form one inlet and outlet 7; and each inlet and outlet 7 is provided with a regulating valve 4, and the regulating valve 4 controls the flow of the smoke; the outline line of the cross section of the smoke guide pipe 3 is a circular structure formed by connecting wavy lines end to end, and the pipe wall of the smoke guide pipe 3 is provided with a plurality of strip-shaped concave parts 5 and strip-shaped convex parts 6 which are parallel to the axis of the smoke guide pipe.

In the specific implementation, the smoke guiding pipe 3 is made of metal materials such as steel, and the expansion and contraction of the smoke guiding pipe are both in the elastic expansion range of the smoke guiding pipe 3.

In specific implementation, if three or more inlets and outlets 7 are arranged, the joint of the branch pipe and the main pipe can be welded by adopting conventional technologies, and the like, and when the smoke guide pipe 1 expands, the joint cannot crack due to larger expansion allowance of other parts of the smoke guide pipe.

The same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it is to be understood that if there is an orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not intended to indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and are not to be construed as limitations of the present patent, and specific meanings of the above terms may be understood by those skilled in the art according to specific situations.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
