Description
Technical field
The present invention relates to sample detecting technical field, especially a kind of high-temperature flue gas that heat tracing function is heated with invariable power
Sampling line.
Background technology
High-temperature flue gas typically refers to the various combustion of industrial boiler such as stationary source such as waste incineration, coal-fired combustion carbon, combustion gas
During the gas that produces, this is a kind of special medium of comparison, under normal circumstances 140 degree or so of the temperature of flue gas, special feelings
Up to 180 degree under condition, can typically there are dust and such as S02, NOX acidic materials, these acidic materials and powder in flue gas in addition
Dirt can be condensed into liquid medium due to temperature drop, flue gas composition can be lost, and this is in flue gas in specific flue extraction process
The problem of being very difficult in sampling process.
Existing heat tracing mode in low temperature situation frequently with self temperature control heating tape, due to the heat tracing temperature of self temperature control heating tape
Up to 120 degree, more than 120 degree frequently with high-temperature constant-power ribbon heater heat tracing, invariable power ribbon heater is with being heated or companion
Thermal chimney is the form by linear contact lay, and poor heat transfer between ribbon heater and fume pipe, thermal field is uneven, also limits it at higher temperature
The use of occasion is spent, such as the occasion more than 160 degree, using just highly difficult, is easily damaged..
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high-temperature flue gas sampling that heat tracing function is heated with invariable power
Line, good with heat-transfer effect, thermal field is uniform, the characteristics of suitable high temperature applicationss are used.
In order to solve the above-mentioned technical problem, the present invention includes some sampling conduits, and the sampling conduit outer wall is enclosed with
Wire sheathing, wherein the wire sheathing on two sampling conduits is connected with power supply respectively, the wire sheathing outer wrapping
There is insulating barrier, all sampling conduits are wrapped integral by heating wire, and the heating wire is respectively with being connected with the metal knitted of power supply
The electricity being provided with heat-insulation layer, the heating wire between several nodes, node is also enclosed with the outside of layer connection, the heating wire
Heated filament two ends are connected with two wire sheathings respectively, and the wire sheathing is nickel plating copper wire braiding layer, and the heating wire is
Nichrome wire.
Further, the heating wire surface is additionally provided with temperature sensor, is set between the temperature sensor and heating wire
It is equipped with insulating tape.
The present invention is programmed with nickel plating copper wire on sampling conduit surface, on the one hand as power source bus, on the other hand adds
The tensile strength of sampling conduit.The heating wire of heating is uniformly densely coated on around sampling conduit, during heating, and thermal field is very equal
Even, heating surface area is very big, and the load of heating wire is very low, available for 170 degree or so of high temperature applicationss.
Brief description of the drawings
Fig. 1 is structural representation of the invention.

The fiber of aluminium, ceramic fibre or waterproof is made or other insulation materials.In order to control the heating-up temperature of heating wire, institute
State the surface of heating wire 4 and be additionally provided with temperature sensor 6, it is exhausted using 3M fluoroplastics between the temperature sensor 6 and heating wire 4
Edge adhesive tape is isolated.
In order that the present invention can arbitrarily be cut, it is provided with the heating wire 4 between several nodes 5, each node
Heating wire two ends be connected respectively with two wire sheathings, the heating wire between each node is actually so formd into parallel connection
Structure, length can cut to the present invention, only at least include two nodes on sampling line to be cut according to demand
5。
