Abstract

The invention relates to the technical field of industrial electrical tracing and discloses an electric tracing pipe with a uniform thermal field. The electric tracing pipe comprises a delivery pipe, wherein three metal braided tapes are arranged on the outer surface of the delivery pipe along the axial direction; the metal braided tapes are connected with electrodes of a three-phase power supply respectively; a plurality of electric heating devices are arranged among the braided tapes; the braided tapes and the electric heating devices are coated with a first insulating layer; a second insulating layer is arranged between the delivery pipe and the braided tapes; and the braided tapes are arranged at equal intervals; and the electric heating devices are evenly arranged on the outer surface of the delivery pipe. The electric tracing pipe only needs to be connected with the power supply when used, so that the electric tracing pipe is relatively convenient to install. Furthermore, the electric heating devices are evenly arranged on a pipe body, so that the pipe body is relatively uniformly heated; the phenomenon of an over-high local temperature is avoided; the energy is saved; and the service lifetime of a product can be prolonged. Furthermore, by three-phase power supply, the current is relatively low; the voltage drop is not obvious; and the relatively long tracing pipe can be manufactured.

Description

The uniform electrical tracing pipe in hot field

Technical field

The present invention relates to industrial electro companion thermal technology field, it is the uniform electrical tracing pipe in a kind of hot field.

Background technology

Electrical tracing pipe in existing market is the additional electrical tracing cable composition of transfer lime mostly, and companion's heat etc. of the sampling pipeline of such as flue gas is all adopt in this way, but this kind of way has many shortcomings, mainly contains:

1, difficulty is installed, companion's heat of the sampling pipeline of some flue gases, sampling tube is all more tiny, but electrical tracing cable is the specification of standard, installs and just seem that comparison is difficult on tiny pipe.

2, accompany hot field uneven, traditional companion's hot mode accompanying-heat cable is bundled on transfer lime or sampling tube, and the way of contact is wire-shaped contact, and the hot field of companion's heat is uneven.

3, owing to accompanying the uneven of heat, want the transmission ofenergy of accompanying-heat cable to, on transfer lime, obviously feeling that the Temperature Ratio of cable is higher, it is particularly that the application scenario of high-temperature gas is especially obvious at media such as flue gas samplings.

4, companion's heat often adopts two core cable, and same companion's thermal power, heart yearn electric current is big, and volts lost is big, and the distance of single-point Power supply is short.

Summary of the invention

The technical problem to be solved in the present invention is to provide the uniform electrical tracing pipe in a kind of hot field, has easy to install and use, and companion's heat is evenly, it may also be useful to the feature of life-span length.

In order to solve the problems of the technologies described above, the present invention comprises transfer lime, the outside surface of described transfer lime is in axial direction provided with 3 metal knitted bands, described braid respectively with the Electrode connection of three-phase supply, being provided with some electric heating devices between described braid, described braid and electric heating melt and are enclosed with the first insulation layer.

The 2nd insulation layer it is provided with between described transfer lime and braid.

Described braid equi-spaced apart is arranged.

Described electric heating device is evenly arranged on the outside surface of transfer lime.

Electrical tracing pipe of the present invention is installed more convenient, and the comparison of being heated of pipe body is even, the phenomenon that local temperature can not be caused too high, and can manufacture longer trace pipe.

Embodiment

Embodiment cited by the present invention; just understand the present invention for helping; should not be construed as limiting the scope of the present invention; for those skilled in the art; without departing from the inventive concept of the premise; the present invention can also being improved and modify, these improve and modify in the scope also falling into the claims in the present invention protection.

As depicted in figs. 1 and 2, the present invention comprises transfer lime 1, and described transfer lime 1 can be tubing or pneumatic tube. If described transfer lime 1 is made up of insulating material, on the outside surface of transfer lime 1, then in axial direction directly it is provided with 3 braids worked out by copper wire 2, if transfer lime 1 has metallic substance to make, then first the 2nd insulation layer 5 is set at the outside surface of transfer lime, this insulation layer 5 can be fluoro-containing plastic layer, is more in axial direction laid on the 2nd insulation layer 5 by metal knitted band 2. Described braid 2 respectively with the Electrode connection of three-phase supply, be welded with some electric heating devices 3 between described braid 2, the quantity of electric heating device and power according to adding heat request determine. This electric heating device 3 can be nichrome wire or electric heating block etc.; it is evenly arranged on the outside surface of transfer lime 1; described braid 2 and electric heating device 3 are enclosed with the first insulation layer 4 being made up of fluoro-containing plastic, thus form layer protective layer at the outside surface of braid 2 and electric heating device 3.

The present invention, by electric heating device and transfer lime overall processing, as long as it is just passable even to connect with the mains in use, therefore installs more convenient, in addition, generating thermal is evenly arranged on pipe body, and the comparison of being heated of pipe body is even, the phenomenon that local temperature can not be caused too high, not only energy-conservation, and the work-ing life of product can be extended, in addition, owing to adopting three phase supply, electric current is less, and voltage reduces not obvious, it is possible to manufacture longer trace pipe.
