The ascension pipe has the beneficial effects that caking tar is not generated or floc blockage does not happen on the heat exchange surface; and when leakage happens to heat exchange pipe components, the heat exchange media can not flow into a coking chamber.
Description
Technical field:
The utility model relates to the upcast on a kind of coking industry pit kiln, is specifically related to the heat exchange type upcast that a kind of waste heat of coke oven crude gas is recycled.
Background technology:
Upcast belongs to an equipment of coke oven, at present, the general coking chamber method of just using of coking enterprise is fired this traditional technology of coke, the coking coal that adds in the coking chamber is heated a large amount of raw gas of back generation, its temperature is at 650 ℃--and 800 ℃, the effect of upcast is exactly that the high temperature raw gas that coking chamber produces is imported effuser, and the waste heat of the high temperature raw gas in the upcast just fails to utilize always, can only waste heat with the cyclic ammonia water cooling.
As far back as the seventies in last century, Shoudu Iron and Steel Co, Taiyuan Iron and Steel Co. adopt the chuck upcast, and chuck internal cooling water absorbs the entrained heat of raw gas and vaporizes, produce steam, want to realize the recycling of heat energy, abbreviate " coke oven coke oven uprising tube apparatus for vapour-cooling " as, once once adopted by how tame coal chemical enterprise.In use the subject matter of Chu Xianing is: these background technologies all do not overcome the difficulty of coal oven dithio-gas heat exchange, heat-transfer surface bonding tar occurs, and floss stops up, and heat-transfer surface leaks influences coke production.Along with the further raising of people to the understanding of importance of high temperature raw gas waste heat recovery, increasing people a kind of equipment that can reclaim high temperature raw gas waste heat that begins one's study.
The utility model content:
The purpose of this utility model provides the heat exchange type upcast that a kind of waste heat of coke oven crude gas is recycled, and it can make heat-transfer surface not produce bonding tar or floss stops up, and heat transferring medium can not flow to coking chamber when leaking appears in the heat transfer tube element.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises upper flange 1, cold media set case 2, cold medium inlet 3, interior pipe 4, thermal medium collection case 5, thermal medium outlet pipe 6, intervalve 7, housing 8, outer tube 9, thermally conductive material 10, housing insulating liner 11 and lower flange 12; Upper flange 1 and lower flange 12 are separately positioned on the two ends up and down of housing 8, the inboard of housing 8 is provided with housing insulating liner 11, outer tube 9 is connected with housing 8, the inside of outer tube 9 is provided with thermally conductive material 10, the inside of thermally conductive material 10 is provided with intervalve 7, the top of intervalve 7 is provided with thermal medium collection case 5, the left side of thermal medium collection case 5 is provided with thermal medium outlet pipe 6, pipe 4 in the inside of intervalve 7 is provided with, the upper end of interior pipe 4 is provided with cold media set case 2, cold media set case 2 is arranged on the top of thermal medium collection case 5, and the left side of cold media set case 2 is provided with cold medium inlet 3.
The utlity model has following beneficial effect: it can make heat-transfer surface not produce bonding tar or floss stops up, and heat transferring medium can not flow to coking chamber when leaking appears in the heat transfer tube element.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises upper flange 1, cold media set case 2, cold medium inlet 3, interior pipe 4, thermal medium collection case 5, thermal medium outlet pipe 6, intervalve 7, housing 8, outer tube 9, thermally conductive material 10, housing insulating liner 11 and lower flange 12; Upper flange 1 and lower flange 12 are separately positioned on the two ends up and down of housing 8, the inboard of housing 8 is provided with housing insulating liner 11, one end of outer tube 9 is connected with housing 8, the other end shutoff, the inside of outer tube 9 is provided with thermally conductive material 10, the inside of thermally conductive material 10 is provided with intervalve 7, the top of intervalve 7 is provided with thermal medium collection case 5, the left side of thermal medium collection case 5 is provided with thermal medium outlet pipe 6, pipe 4 in the inside of intervalve 7 is provided with, the upper end of interior pipe 4 is provided with cold media set case 2, and cold media set case 2 is arranged on the top of thermal medium collection case 5, and the left side of cold media set case 2 is provided with cold medium inlet 3.
The medium that described cold medium inlet 3 and thermal medium outlet pipe 6 flow, can be water, water vapour or their mixture, can be other gases also, and not produce chemistry or physical change such as oxidation, corrosion with heat-transfer surface under the high temperature, be stable medium under the heat transfer state.
The principle of work of this embodiment is: heat transferring medium enters in the cold media set case by cold medium import, entered the interior pipe of heat transfer tube element more respectively by cold media set case, the other end by interior pipe enters interior pipe and the formed annular space of intervalve, heat transferring medium enters thermal medium collection case by the other end of this annular space again, is drawn by the thermal medium outlet pipe that links to each other with thermal medium collection case again; Raw gas in upcast is with the outer tube heating of heat transfer tube element, the thermally conductive material that the heat that outer tube absorbs is filled in intervalve and the formed annular space of outer tube is passed to intervalve with heat, intervalve is passed to heat by intervalve and interior pipe again and is formed heat transferring medium in the annular space, and heat transferring medium is heated to compile by the thermal medium outlet pipe by thermal medium collection case and draws.Raw gas is flowed out upcast by heat transferring medium cooling back, realizes the waste heat recovery of raw gas.
