Detailed description of the invention
Embodiment
Referring to shown in Fig. 1; the present embodiment the technical scheme is that the heat exchange type ascending tube that a kind of waste heat of coke oven crude gas recycles, and comprises upper flange 1, cylinder 2, inner lining as thermal insulation material 3, heat exchanger tube element outer tube 4, heat exchanger tube element inner tube 5, sealing plate 6, lower flange 7, protection atmospheric pressure alarm 8, protective gas adapter 1, protective gas house steward 10, thermal medium outlet pipe 11, thermal medium header 12, Heat Conduction Material 13, cold medium header 15, protective gas adapter 2 14, cold medium inlet 16, protective gas adapter 3 17；nullUpper flange 1、Lower flange 7 is separately positioned on the two ends up and down of cylinder 2，Constitute tedge，Tedge cylinder 2 inwall is provided with inner lining as thermal insulation material 3，If being provided with the Heavenly Stems and Earthly Branches in tedge cylinder by heat exchanger tube element outer tube 4、Heat Conduction Material 13、The heat exchanger tube element of heat exchanger tube element inner tube 5 composition，The two ends of heat exchanger tube element outer tube 4 are connected with cylinder 2，The two ends of the outer tube 4 of heat exchanger tube element and the inner tube 5 of heat exchanger tube element are respectively connected together，Formed and seal chamber，At annular seal space indoor filling Heat Conduction Material 13 and protective gas，The cold medium inlet 16 of heat exchanger tube element and thermal medium outlet pipe 11 are separately positioned in cold medium header 15 and thermal medium header 12，The outer tube 4 of heat exchanger tube element contacts with the raw coke oven gas in tedge，The heat transfer medium region of heat exchanger tube element and raw coke oven gas region in tedge housing be two separate、The space closed.
Described cold medium is entered in cold medium header 15 by cold medium inlet 16, the inner tube 5 of some heat exchanger tube elements it is reallocated to by cold medium header 15, flow to thermal medium header 12 by the inner tube 5 of heat exchanger tube element again collect, derive through thermal medium outlet pipe 11, high temperature raw coke oven gas contacts with the outer tube 4 of heat exchanger tube element in being entered tedge by lower flange 7, heat is passed to heat transferring medium through heat exchanger tube element inner tube 5 through Heat Conduction Material 13 and gas after being heated by high temperature raw coke oven gas by the outer tube 4 of heat exchanger tube element, medium is heated, and raw coke oven gas flows out through upper flange 1 after being lowered the temperature.
Described protective gas enters protective gas adapter 1 through protective gas house steward 10; the annular seal space formed by the annular space between heat exchanger tube element inner tube 5 and heat exchanger tube element outer tube 4 is entered indoor through protective gas adapter 1; heat exchanger tube element protective gas between layers is connected by protective gas adapter 2 14; the effects such as aerofluxus are played in protective gas adapter 3 17, are provided with protection atmospheric pressure alarm 8 in protective gas adapter 1.
Described heat exchanger tube element gap between layers is linked together by sealing plate 6.
Described heat transferring medium can be water, steam or their mixture, it is also possible to is not produce chemistry or the physical change such as oxidation, corrosion under other gases or liquid, and high temperature with heat-transfer surface, is stable medium under heat transfer conditions.
The present embodiment has the beneficial effect that and makes heat-transfer surface be not likely to produce bonding tar or floccule blocking, does not corrodes；Because the annular seal space indoor between heat exchanger tube element inner tube 5 and heat exchanger tube element outer tube 4 are filled with the big Heat Conduction Material of heat conductivity and gas, the effect improving heat transfer efficiency can be played；Additionally; the gas filled in chamber; normal condition downforce is stable; when inner tube is damaged; the heat transferring medium that pressure is higher can enter the annular space between heat exchanger tube element inner tube 5 and heat exchanger tube element outer tube 4; cause the rising of filled gas pressure; the protection atmospheric pressure alarm 8 making monitoring chamber gas pressure inside starts; operative employee can judge which platform tedge heat exchanger there is a problem according to reporting to the police at once; being turned off by the heat transferring medium terminal valve of this tedge heat exchanger immediately, heat transferring medium is thus without leaking into carbonization chamber；When outer tube damages, because of the gas pressure filled in managing the outer raw coke oven gas pressure chamber less than inner and outer pipes formation, therefore, the gas filled can spill, make protection atmospheric pressure alarm 8 system start-up in monitoring chamber, equally, operative employee also can quickly judge it is which platform tedge heat exchanger is out of joint, and it is taken measures, because the change according to filled gas pressure can cause protection atmospheric pressure alarm 8 to start, serve the effect avoiding heat transferring medium to leak into carbonization chamber, so the gas filled is referred to as protective gas, solve this area to wish for a long time to solve the technical problem that.
The above, it is merely to illustrate the technical solution of the utility model and unrestricted, other amendment or equivalent that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in the middle of right of the present utility model.
