Abstract

The invention relates to a liquid pipeline heating and heat-preserving system, which is characterized in that each heating and heat-preserving body can be independently used accordingly, and the plurality of heating and heat-preserving bodies can be connected and simultaneously used together along with raised power according to actual demand. According to the technical scheme of the invention, as the heating and heat-preserving bodies are arranged at the exterior of the liquid pipeline, smooth flow of liquid in the pipeline and normal operation of the device are ensured in low-temperature environment. The liquid pipeline heating and heat-preserving system has the advantages of fast heating rate, strong following heating ability, large heating area, no arc striking in wire breakage, adjustable power and convenient use.

Description

Liquid line heating and thermal insulation system

Technical field

Patent of the present invention relate to a kind of liquid line heating and thermal insulation heating, especially winter room temperature liquid pipeline heating and thermal insulation system.

Background technique

Because northern area outside work in winter temperature is lower, in pipeline, liquid is easy to freeze, and cause liquid communication not smooth, impact normally works.In order to ensure the fluency of flow of fluid in pipeline, existing employing twines the heating of thermal insulating material electric blanket simply in advance, the mode that fire is roasting, is easy to realize; But said method also exists problems.Except there is the safety problems such as easy breaking out of fire, winding thermal insulating material or coating pitch can face the problem that can only be incubated and can not heat in advance, only play preventive effect, and do not play the effect of solution.And outer chemical fibre thermal insulating material cannot ensure the job security of the aspect such as fire-resistant, working life breaks, and cannot reuse, bring significant limitation to use.

Summary of the invention

Goal of the invention

Patent of the present invention technical problem to be solved is to provide a kind of for liquid transmission pipeline, use a kind of heating rate fast, high insulating effect, strong with type heating efficiency, coverage scale 100%, can free adjustment heating area, the not starting the arc of breaking, power adjustable, can realize the liquid line heating and thermal insulation system of keeping the safety in production.

Technological scheme

Liquid line heating and thermal insulation system, each heating and thermal insulation body is inner to be made up of heating and insulation two-part, and heating part utilizes carbon fiber heating wire to heat.Lagging outside is also provided with inlet wire, outlet terminal, is fixedly connected with cingulum.Can be worked by the multiple heating and thermal insulation body of serial or parallel connection by inlet wire, outlet terminal simultaneously.

Advantage and effect

The advantage that patented technology of the present invention is compared with prior art had is:

(1) easy to use, according to the shape unrestricted choice heating and thermal insulation body of device;

(2) according to the quantity of the large freedom in minor affairs adjustment heating and thermal insulation body of heating area, serial or parallel connection uses;

(3) heating unit long service life, tensile strength is high, stable chemical performance, can with any alternating bending of type;

(4) electric heating conversion ratio is high, and electric heating conversion efficiency is greater than 99%; 60 seconds Nei Keda 50 DEG C;

(5) to break the not starting the arc, effectively stop the generation of fire.

1-heating and thermal insulation body in figure; 2-power output end; 3-portable single input and multi-output power supply voltage control case; 4-carbon fiber heating wire; 5-heat-shrink tube; 6-is outer; 7-thermal insulation layer; 8-internal layer; 9-is fixedly connected with cingulum.

Embodiment

Below in conjunction with accompanying drawing, patent of the present invention is described in detail.Liquid line heating and thermal insulation system, comprise some quantity be made up of with lagging carbon fiber heating wire (4) closely can be wrapped in heating and thermal insulation body (1) outside pipeline by being fixedly connected with cingulum.The 36 volts of power supplys exported by portable single input and multi-output power supply voltage control case (3) provide electric power.The heating unit that each heating and thermal insulation body is formed by carbon fiber heating wire (4) and heat-shrink tube (5) and insulation, oil resistant, waterproof, waterproof, fire-retardant, etch-proof thermal insulator are formed.Thermal insulator is made up of oil resistant, waterproof, waterproof, fire-retardant, etch-proof internal layer (8) and skin (6) and thermal insulation layer (7).Each heating and thermal insulation body has a power input and a power output end simultaneously, and independently can use and can connect use.Portable single input and multi-output power supply voltage control case has 1 ~ 5 power output end (2).In actual pipeline situation, for long straight tube road, liquid line heating and thermal insulation system can be connected use; Short complex pipeline liquid line heating and thermal insulation system can in parallelly be used again; For the mode that more complicated actual pipeline also can use series connection to combine with parallel connection
