Background technology
At present, the process pipelines of most of petrochemical production device, tower liquid level and interface plate need the equipment of companion's heat mainly contain tower, auxiliary device and process pipe etc. always with steam or the electric tracing heat of keeping company.Its operation principle must have certain thermal source, replenishes the thermal loss of insulation equipment by tracing system, and these need to accompany the device structure of heat complicated, thereby it is more complicated to lay tracing system, and have certain disadvantage in running.
1, the deficiency of steam tracing: the steam tracing cost is higher.When the steam tracing pipeline moves in the winter time, " run, drip, leak " phenomenon often appears, very easily cause the personnel's of patrolling and examining personal injury, increased manual maintenance difficulty and maintenance cost.Tracing steam is many, and steam tracing occurs congealing even the pipeline bursting by freezing easily, has both affected steam pipe system pressure, flow equilibrium, is difficult to again thaw from full factory steam pipe system, affects device and steadily produces, and causes device to stop work when serious.
2, electrically heat tracing deficiency: the steam tracing cost is also higher, and has certain potential safety hazard, in case electric leakage, sparking phenomenon occur, will have a strong impact on the safety in production of device.
The utility model content
The purpose of this utility model is: provide a kind of fractionating column liquid level gauge to put from heating, self-loopa companion hot charging, safely, steadily, effectively guarantee high temperature position equipment companion heat, reduce energy consumption.Overcome steam tracing and electrically heat tracing power consumption high, have a shortcomings such as potential safety hazard.
The technical solution adopted in the utility model is: the fractionating column liquid level gauge is put from heating, self-loopa companion hot charging, comprises fractionating column and liquid level gauge, and liquid level gauge is used for showing the liquid level of fractionating column inside by the side of the good valve installation of connecting line at fractionating column; It is characterized in that: the outer wall coiling at fractionating column has a carbon steel heat absorption coil pipe; Outer wall coiling at liquid level gauge has a red copper radiator coil tube; The upper end of carbon steel heat absorption coil pipe is connected by the first articulation with the upper end of red copper radiator coil tube; Be connected with an addition funnel by threeway and pipeline on a side pipe line of the first articulation, the pipeline in the addition funnel bottom is connected with hand-operated valve; The lower end of carbon steel heat absorption coil pipe is connected by the second articulation with the lower end of red copper radiator coil tube; Side pipe line in the second articulation is connected with a threeway, by three-limb tube line and exhaust-valve; In carbon steel heat absorption coil pipe and red copper radiator coil tube, be perfused with conductive fluid.
Described conductive fluid is the low solidifying conduction oil of AH-50D.
Utilize fractionating column that the conductive fluid of carbon steel heat absorption coil pipe is heated, conductive fluid flows into the red copper radiator coil tube from the upper end.Conductive fluid in the red copper radiator coil tube is incubated liquid level gauge.By conductive fluid is repeatedly heated, cools off, the each several part density that makes closed circulation is different and cause to flow and reach purpose from heating, self-loopa companion heat.
The beneficial effects of the utility model: the utility model fractionating column liquid level gauge is put from heating, self-loopa companion hot charging, can utilize the waste heat safety of fractionating column, steadily, effectively the liquid level gauge of fractionating column is incubated, and reduces energy consumption.Overcome the deficiency that steam tracing and electrically heat tracing power consumption are high, have potential safety hazard.
