Description

Technical Field

[0001] This utility model belongs to the field of experimental coke ovens and relates to a raw coal gas emission pipeline for an experimental coke oven. Background Technology

[0002] A "test coke oven" is a small / medium-sized experimental device that simulates the industrial coking process. Its core purpose is to study the effects of coal quality, coal blending scheme, and coking process parameters on "coke quality" and "coking by-products (such as coke oven gas)" in laboratory or pilot-scale settings, providing data support for the production optimization of industrial coke ovens, the application of new coal types, or the development of processes.

[0003] During the experimental coke oven test, raw coal gas was generated. This raw coal gas was introduced into the incinerator through a riser pipe for combustion, and after dust removal and other measures, it was discharged into the atmosphere after meeting emission standards. The raw coal gas contained combustible gases (hydrogen, methane, carbon monoxide, etc.), tar mist, and dust. The tar mist and dust cooled rapidly inside the riser pipe and were easily adsorbed onto the inner wall of the riser pipe. Combined with the action of dust, the tar mist and dust easily coked on the inner wall of the riser pipe, making cleaning difficult. Utility Model Content

[0004] To overcome the deficiencies in the aforementioned related technologies, this utility model proposes a raw gas emission pipe for a test coke oven, which facilitates the cleaning of the raw gas emission pipe for the test coke oven.

[0005] To achieve the above technical objectives, this utility model provides a raw gas emission pipe for a test coke oven. The raw gas emission pipe for the test coke oven includes: a test coke oven, a riser pipe, a connecting component, and an incinerator. The riser pipe is a vertically arranged pipe, and its lower end is connected to the carbonization chamber of the test coke oven. One end of the connecting component is connected to the upper end of the riser pipe. The other end of the connecting component is connected to the incinerator.

[0006] The connecting component is a box-shaped structure. A lower connecting pipe is provided on the lower side wall of the connecting component, and the lower connecting pipe is connected to the upper end of the rising pipe. An upper connecting pipe is provided on the upper side wall of the connecting component, and the upper connecting pipe is connected to the incinerator. The orthographic projections of the lower connecting pipe and the upper connecting pipe on the horizontal plane do not overlap. An opening and a cover plate adapted to the opening are provided on the side wall of the connecting component.

[0007] Preferably, a negative pressure fan is provided between the connecting member and the incinerator. The negative pressure fan is fixed inside the upper connecting pipe and maintains negative pressure in the connecting member.

[0008] Preferably, a high-temperature resistant sealing strip is provided at the edge of the opening.

[0009] Preferably, the cover plate is fixedly connected to the connecting member by bolts, thereby sealing the opening.

[0010] Alternatively, the cover plate is hinged to the connecting member and fixed to the connecting member by a latch, and the cover plate seals the opening.

[0011] Preferably, both ends of the opening extend to the corresponding two sidewalls of the connecting member. Furthermore, both ends of the opening extend at least to the vertical plane of symmetry of the connecting member.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention features a connecting component with an opening, allowing raw coal gas to be introduced into the incinerator via a negative pressure fan. The connection component is kept under negative pressure to prevent gas leakage during testing. Furthermore, when the test is stopped, the cover plate can be removed, allowing personnel to clean the water supply pipe and the inside of the connecting component through the opening, removing tar and coke from the riser pipe and the inner wall of the connecting component.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] like Figures 1 to 4 As shown, this utility model provides a raw gas emission pipe for a test coke oven 1. The raw gas emission pipe for the test coke oven 1 includes: a test coke oven 1, a riser pipe 2, a connecting member 3, and an incinerator 4. The riser pipe 2 is a vertically arranged pipe, and its lower end is connected to the carbonization chamber of the test coke oven 1. One end of the connecting member 3 is connected to the upper end of the riser pipe 2. The other end of the connecting member 3 is connected to the incinerator 4.

[0023] The connecting component 3 is a box-shaped structure. A lower connecting pipe 31 is provided on the lower side wall of the connecting component 3, which is connected to the upper end of the rising pipe 2. An upper connecting pipe 32 is provided on the upper side wall of the connecting component 3, which is connected to the incinerator 4. The orthographic projections of the lower connecting pipe 31 and the upper connecting pipe 32 on the horizontal plane do not overlap. An opening 33 and a cover plate 34 adapted to the opening 33 are provided on the side wall of the connecting component 3.

[0024] A negative pressure fan is provided between the connecting component 3 and the incinerator 4. The negative pressure fan is fixed inside the upper connecting pipe 32 and maintains negative pressure in the connecting component 3.

[0025] The connecting component 3 is made of stainless steel or cast iron. The connecting component 3 can provide a more spacious cleaning space for the staff, and at the same time, the orthogonal projections of the lower connecting pipe 31 and the upper connecting pipe 32 on the horizontal plane do not overlap, which can reduce the adhesion of tar mist to the negative pressure fan and the incinerator 4.

[0026] A high-temperature resistant sealing strip is provided at the edge of the opening 33.

[0027] The cover plate 34 is fixedly connected to the connecting member 3 by bolts, and seals the opening 33.

[0028] Alternatively, the cover plate 34 is hinged to the connecting member 3 and fixed to the connecting member 3 by a latch, and the cover plate 34 seals the opening 33.

[0029] Both ends of the opening 33 extend to the corresponding two side walls of the connecting member 3. Furthermore, both ends of the opening 33 extend at least to the vertical plane of symmetry of the connecting member 3.

[0030] The larger opening 33 makes it easier for staff to clean the inside of the riser pipe 2 and the connecting part 3.

[0031] The operating mode of this utility model is as follows:

[0032] The raw coal gas generated during the operation of the test coke oven 1 enters the incinerator 4 for combustion through the riser pipe 2 and the connecting pipe 3. At the same time, the negative pressure fan guides the raw coal gas from inside the connecting pipe 3 into the incinerator 4, maintaining a negative pressure state inside the connecting pipe 3.

[0033] When a lot of tar or coking accumulates on the inner walls of the riser pipe 2 and the connecting part 3, the cover plate 34 can be removed or opened, and the staff can use cleaning tools and chemicals to clean the inner walls of the riser pipe 2 and the connecting part 3.

[0034] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
