Background technique
When the using plasma torch was handled hazardous waste, the temperature of hazardous waste processing region was general 〉=1300 ℃, and this zone is weary oxygen environment, so, this processing region with extraneous must be isolated mutually, required high temperature, weary oxygen condition when guaranteeing to handle refuse.It is high-temperature fusion shape liquid glass body material that hazardous waste is handled residual substance, when arrival is a certain amount of, this zone is linked up, so that discharge residual substance with extraneous.In order to arrive this requirement, need a kind of novel thermal valve door of development.
Summary of the invention
The purpose of this utility model provides a kind of high temperature required when guaranteeing to handle refuse, the elevated temperature heat valve of weary oxygen condition.
The utility model is to realize like this, it comprises the graphite heating pipe elevated temperature heat valve, the outside of graphite heating pipe is provided with outer stoneware pipe, the outside of outer stoneware pipe is provided with heating coil, the upper end of graphite heating pipe links to each other with the melt region in plasma incinerator waste disposal district, the lower end of graphite heating pipe is positioned at the central authorities of base for supporting, outer stoneware pipe is formed an enclosed space with following ceramic ring and is seated on the base for supporting, the graphite heating pipe is wrapped in wherein, temperature controller is connected with the graphite heating pipe by temp probe, temperature controller is connected with power supply, power supply is connected with transformer, transformer is connected with heating coil, and cooling water inserts the intake-outlet of heating coil.
Be provided with the ceramic fiber heat keeper between described outer stoneware pipe and the heating coil.
The utility model has the advantages that, High temperature valve graphite heating pipe top links to each other with the melt region in plasma incinerator waste disposal district, because melt region is weary oxygen, and is full of molten liquid glass body material, so under high temperature condition, graphite heating Guan Buhui is damaged.When needs are discharged residual waste, power transformer produces vortex heat to the superaudio electric current that heating coil provides in the graphite heating pipe, will heat graphite-pipe and be heated to more than 1300 ℃, molten liquid glass body material can flow out along the heating graphite-pipe, arrives the purpose of deslagging.When deslagging finishes, cut off heating current, the molten liquid glass body material in the passage is cooled and solidified gradually, the melt region and the external world can be separated.The bottom of High temperature valve base for supporting links to each other with the discharge port assembly of sealing, during work, by inflation inlet, fills the post of protective gas nitrogen, and is not oxidized under high temperature condition in order to the outlet of protection heating graphite-pipe.
Description of drawings
Fig. 1 is an elevated temperature heat valve mechanism schematic representation provided by the utility model.
Among the figure, 1 heating coil, 2 heating graphite-pipes, 3 outer stoneware pipes, 4 ceramic fiber heat keepers, 5 times ceramic rings, 6 base for supporting, 7 temperature controllers, 8 power supplys, 9 transformers, 10 cooling waters.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made following detailed description:
It comprises graphite heating pipe 2 cylindraceous a kind of elevated temperature heat valve, the external packets of graphite heating pipe 2 is wrapped with outer stoneware pipe 3, the outside of outer stoneware pipe 3 is a ceramic fiber heat keeper 4, the outside of ceramic fiber heat keeper 4 is a heating coil 1, the upper end of graphite heating pipe 2 links to each other with the melt region in plasma incinerator waste disposal district, the lower end of graphite heating pipe 2 is positioned at the central authorities of base for supporting 6, outer stoneware pipe 3 is formed an enclosed space with following ceramic ring 5 and is seated on the base for supporting 6, graphite heating pipe 2 is wrapped in wherein, and place the central authorities of heating coil 1, temperature controller 7 is connected with graphite heating pipe 2 by temp probe, temperature controller 7 is connected with power supply 8, power supply 8 is connected with transformer 9, and transformer 9 is connected with heating coil 1, and cooling water 10 inserts the intake-outlet of heating coil 1.
Down, High temperature valve graphite heating pipe 2 tops link to each other with the melt region in plasma incinerator waste disposal district in working order, and the bottom of its base for supporting 6 links to each other with the discharge port assembly of sealing.Outer stoneware pipe 3 and following ceramic ring 5 compositions one enclosed space are wrapped in graphite heating pipe 2 wherein, and place heating coil central authorities, insulate with ceramic fibre mat 4 between heating coil and the outer stoneware pipe 3 and are incubated.Heating coil forms with the coiling of hollow rectangle copper tube, and during heating, cooling water cools off the heating coil rectangle by the water inlet and outlet on the heating coil.The superaudio heating power supply offers heating coil by transformer.During work, also need input protection gas nitrogen from spout assembly.
Wherein, the graphite heating pipe also is the discharge route of high-temperature fusion refuse as heating element simultaneously; Outer stoneware pipe is formed insulation, insulating assembly with following ceramic ring, and the while is as the support of graphite heating pipe; The outer stoneware pipe of ceramic fiber heat keeper maskable keeps the distance between heating coil and the outer stoneware pipe, prevents that outer stoneware pipe from meeting cold temperature decrease and break under high temperature condition; Temperature controller assurance graphite heating pipe temperature is regulated in controlled range; The input of protective gas nitrogen guarantees that the graphite heating pipe is not oxidized under high temperature condition.
