Description
Technical field
The utility model relates to sample detecting technical field, especially a kind of high-temperature flue gas sampling line with invariable power heating companion hot merit energy.
Background technology
High-temperature flue gas typically refers to stationary pollution source as the gas produced in waste incineration, various Burning Process for Industrial Boiler such as coal-fired combustion carbon, combustion gas etc., this is a kind of more special medium, the temperature about 140 degree of flue gas under normal circumstances, in particular cases can reach 180 degree, dust generally can be there is in addition and as acidic materials such as S02, NOX in flue gas, these acidic materials and dust are in specific flue extraction process, liquid medium can be condensed into because temperature declines, flue gas composition can be lost, and this is very difficult problem in flue gas sampling process.
Existing companion's hot mode often adopts self temperature control heating tape at low temperature situation, because companion's hot temperature degree of self temperature control heating tape is up to 120 degree, normal employing high-temperature constant-power ribbon heater companion's heat more than 120 degree, invariable power ribbon heater with heated or accompany thermal chimney to be lean on the form of linear contact lay, poor heat transfer between ribbon heater and fume pipe, thermal field is uneven, also its use in higher temperature occasion is limited, such as occasion more than 160 degree, uses just very difficult, easily damages.。
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high-temperature flue gas sampling line with invariable power heating companion hot merit energy, and have heat-transfer effect good, thermal field is even, is applicable to the feature that high temperature occasion uses.
In order to solve the problems of the technologies described above, the utility model comprises some sampling conduits, described sampling conduit outer wall is enclosed with wire sheathing, wire sheathing wherein on two sampling conduits is connected with power supply respectively, described wire sheathing is wrapped with insulation course, all sampling conduits are integrally wrapped by heating wire, and described heating wire is connected with the wire sheathing being connected with power supply respectively, are also enclosed with heat-insulation layer outside described heating wire.
Further, described heating wire surface is also provided with temperature sensor, is provided with para tape between described temperature sensor and heating wire.
Preferably, described wire sheathing is nickel plating copper wire braid.
Preferably, described heating wire is nichrome wire.
Further, described heating wire is provided with several nodes to work out to be with two strip metals as electrode successively and be connected.
The utility model has nickel plating copper wire in the establishment of sampling conduit surface, on the one hand as power source bus, adds the tensile strength of sampling conduit on the other hand.The heating wire of heating is evenly coated on around sampling conduit thick and fast, and during heating, thermal field is very even, and heating surface area is very large, and the load of heating wire is very low, can be used for the high temperature occasion of about 170 degree.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment cited by the utility model; just understand the utility model for helping; should not be construed as the restriction to the utility model protection domain; for those skilled in the art; under the prerequisite not departing from the utility model thought; can also improve the utility model and modify, these improve and modification also falls in the scope of the utility model claim protection.
The utility model comprises some sampling conduits 1, and as embodiment of the present utility model, as shown in Figure 1, described employing pipeline is two.Described sampling conduit 1 outer wall is enclosed with wire sheathing 2, and described wire sheathing 2 is nickel plating copper wire braid, and the wire sheathing 2 on two sampling conduits 1 is connected with power supply 8 respectively, on the one hand as the bus of heater wire; Increase the tensile strength adopting pipeline 1 on the other hand.Described wire sheathing 2 is wrapped with insulation course 3, and described insulating layer material can be high-temperature resistance plastice or high-temperature resistant rubber or other high-temperature insulation materials.All sampling conduits are integrally wrapped by heating wire 4, described heating wire 4 is connected with the wire sheathing being connected with power supply respectively, also being enclosed with heat-insulation layer 7 outside described heating wire 4, the fiber of alumina silicate, ceramic fiber or waterproof can be adopted to make, also can be other insulation materials.In order to control the heating-up temperature of heating wire, described heating wire 4 surface is also provided with temperature sensor 6, adopts the fluoroplastic insulation adhesive tape of 3M to isolate between described temperature sensor 6 and heating wire 4.
Can cut arbitrarily to make the utility model, described heating wire 3 is provided with several nodes 5, heating wire two ends between each node are worked out to be with two strip metals respectively and are connected, so in fact, the heating wire between each node is defined parallel-connection structure, can length cut the utility model according to demand, as long as cut sample line at least includes two nodes 5.
