Abstract

The utility model pertains to a heating device for the liquid transfer pipeline and an automatic control and high efficient pipeline heater, which is a warming device that is essentially applied in the liquid transfer pipeline of the petroleum industry system. A smoke pipe 10 and an oil inlet and outlet pipe 9 are arranged in a tank body 7 and a pressure relief valve 8 and a vacuum pressure gauge 6 are arranged above the tank body 7; an automatic igniting thermostat 4 is arranged at the lower part of the tank body 7 and a burner 2 and a fire tube are arranged at the lower end of the tank body 7, while a smoke box 3 and a smoke tube 5 that are arranged at the upper part of tank body 7 form a complete sealed and closed heating device and superconductive medium fired coal is applied. The utility model has the advantages of automatic adjustment of temperature, reasonable and advanced structure, convenient mounting and maintenance, safety and reliability, rapid temperature raising and high thermal efficiency, which is an upgraded product for heating the liquid transfer pipeline.

Description

From the efficient pipeline heater of temperature control

One, technical field:

The utility model belongs to the liquid conducting pipes firing equipment, is mainly used in the heating apparatus of the fluid pipeline conveying of petroleum industry system.

Two, technical background:

At petroleum industry system,, often to carry out heating process for the smooth delivery of power petroleum resources in the past, commonly used with regard to those water jacket furnaces, these product structures are original, do not represent state-of-the-art technology, with original water jacket furnace heating operation trouble, and consumes energy is many, and the thermal efficiency is low.

Three, summary of the invention:

The purpose of this utility model provides from the efficient pipeline heater of temperature control.It is the regeneration product that improves design on former water jacket furnace basis.It is mainly by tank body, burner, smoke pipe, light a fire attemperating unit and pressure-relief valve etc. constitute automatically, smoke pipe and turnover oil pipe are installed in tank body, pressure-relief valve and pressure vacuum gauge are installed above tank body, downside at tank body is equipped with automatic igniting attemperating unit, at tank body one end burner and fire tube are installed, smoke box and chimney constitute the heater of the airtight sealing of a cover; Adopt the superconductive medium heating agent.Its beneficial effect is to adopt temperature to regulate automatically, advanced person rational in infrastructure, and installation and maintenance are convenient, and safe and reliable, quick heating, thermal efficiency height are the renewal products that liquid conducting pipes is heated.

Four, description of drawings:

As figure is overall structure schematic diagram of the present utility model.

Among the figure 1, fire tube, 2, burner, 3, smoke box, 4, the attemperating unit of lighting a fire automatically, 5, chimney, 6, pressure vacuum gauge, 7, tank body, 8, pressure-relief valve, 9, the turnover oil pipe, 10, smoke pipe,

Five, embodiment:

As seen from the figure, smoke pipe 10 and turnover oil pipe 9 are installed in tank body 7, oil pipe 9 is installed as coiling type version in tank body 7, pressure-relief valve 8 and pressure vacuum gauge 6 are installed above tank body 7, downside at tank body 7 is equipped with automatic igniting attemperating unit 4, burner 2 and fire tube 1 are installed in tank body 7 one end bottoms, and top is installed smoke box 3 and is formed with chimney 5.

By above be like this when installing implementation and operation, when combustible gas enters burner 2 through igniting attemperating unit 4 automatically, the ignited flammable gas of lighting a fire automatically sprays into fire tube 1 to flame by burner 2, enters atmosphere through smoke pipe 10 by chimney.The heat energy that flame produces is by superconduction composite chemical medium in fire tube 1, smoke pipe 10 heating tanks.When temperature reached medium gasification temperature (55 ℃), medium began gasification, and the steam of generation is full of a jar interior vacuum rapidly, transfusion coil pipe in the heating tank, jar Nei Wenduyin heated medium heat absorption and lowering, the steam condensation is separated out liquid and is sink to pot bottom liquid and is heated once more; So circulation is imported heat in the medium that needs heating fast by superconductive medium (heating agent).The liquid output of transfer line is equipped with the electronic temperature measurement contact in jar, sets the temperature of heated medium as required.Temperature control system starts when drain pipe liquid reaches set temperature value, turns down the output tolerance of fuel gas automatically, makes heater be in automatic control state, thereby guarantees the safety of system, also reaches the scientific utilization of the energy.

For the safety of guaranteeing tank body is equipped with pressure-relief valve 8 above tank body 7, after the aging perforation of transfusion coil pipe in the jar, be full of liquid in jar, pressure raises, but when reaching 0.5Mpa, pressure-relief valve starts, and liquid flows out from pressure-relief valve 8, guarantees being perfectly safe of system.

Product considers that in designing and developing various applied environment is different with power demand, has developed to vary in size model and adapt to the field and the various products of multi-purpose station varying environment use.Fuel adopts natural gas or oil well association sleeve pipe gas.Because system adopts the superconductive medium heating agent.Therefore in heating process, need not to supply water, thereby more adapt to open-air applied environment.(gaseous-pressure is 0.02--0.03Mpa).

This product utilizes sealed vacuum unbalanced system and the little physical characteristic of heat of transformation conduction energy loss in heating process, therefore quick heating, the heat conduction is fast, pressure is low, the thermal efficiency produces the thing heat during energy burning and is absorbed fast up to 90%, and thermal source is fully utilized.

According to investigations, the firing equipment of using in the existing liquid-transport pipe-line adopts the heat-conducting oil heating except that part, and major part still is heated to be the master with water jacket furnace, and the thermal efficiency of water jacket furnace is many at 60-70%.Increased super heat-conductive pipe in the water jacket furnace that has and made structure become complicated in order to improve the thermal efficiency, its efficient is also many about 80%.Because of the thermal efficiency is low, need irregularly to add water, but bad weather have to stop heating when sending water not increase, and has influenced ordinary production to water jacket furnace.

Adopt this cover heater efficiency of heating surface can improve 20-25%, adopt superconductive medium in jar, heating in vacuum without water power, is not afraid of and is frozen, can be with burning with stopping.Especially superconductive medium does not fire the service life that not quick-fried, nonpoisonous and tasteless, non-scaling, incorrosive characteristic have prolonged heater.
