The utility model is characterized in that: the burning chamber is divided into two parts by the horizontally arranged fire grate, and the upper part is provided with a coal burning stove door and a fuel gas interface, and the lower part is provided with a dreg eliminating stove door. The middle of the spiral oil pan tube on the upper part of the stove body is uprightly provided with a plurality of fire tubes, and the upper and lower ports of the fire tube are respectively communicated with the smoke vent on the upper part and the burning chamber on the lower part. The outside walls of all the fire tubes are respectively sealed to the medium heating cavity by the upper and lower clapboards and the stove body, and the upper part of the medium heating cavity is extended to a medium putting tube. The utility model adopts the burning coal and fuel gas for heating, and the burning heat heats the medium in the stove through a plurality of fire tubes with high heating effect and even temperature adding.

Description

A kind of vertical oil country tubular good fire coal, gas two-purpose heating furnace

One, technical field:

The utility model relates to the heating apparatus of oilfield oil pipeline, especially a kind of vertical oil country tubular good fire coal, gas two-purpose heating furnace.

Two, technical background: a lot of oil wells in oil field are away from block station or oil storage tank, its oil pipeline is long, and the particularly high content of wax, the oil transportation in winter of high viscosity oil well be difficulty more, in order to make reducing crude oil viscosity, reduce the oil-piping internal pressure, need in the oil well oil pipeline, heating apparatus be installed.Combustion gas water jacket furnace, electric furnace, pneumoelectric dual-purpose heating stove are extensively adopted in the oil field at present, and crude oil in the oil well oil pipeline is carried out heating and viscosity reducing.Relevant by retrieval patent documentation can be divided into: a class belongs to gas-fired heater, needs sufficient stable source of the gas, need lay steam line, and great in constructing amount, investment is high, causes the crude oil cost height.One class belongs to electric heater unit, and electric thermal power is bigger, needs to increase the needs that the oil well transformer capacity could satisfy oil pumper and electric furnace, has increased the cost of crude oil.Also have a class pneumoelectric dual-purpose heating stove, though be that combustion gas combines with electrical heating, the power consumption expense still is higher, increases cost of crude oil production.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of energy-conservation, vertical oil country tubular good fire coal, gas two-purpose heating furnace efficiently are provided.

Its technical scheme is: comprises vertical cylinder shape body of heater and the spiral oil coil that is installed in the body of heater internal upper part, is installed in the combustion chamber of body of heater bottom, and the liquid level gauge, safety valve, oil-piping joint and the exhaust opening composition that are installed in the body of heater outside.Described combustion chamber is divided into two parts up and down by transversely arranged fire grate, and top is provided with coal-fired fire door and combustion gas interface, and the bottom is provided with the deslagging fire door.Vertical distribution many fire tubes at the spiral oil coil middle part of upper of furnace body, the upper and lower port of all fire tubes connects with the exhaust opening of top and the combustion chamber of below respectively, the upper and lower port outer wall of all fire tubes respectively by on lower clapboard and body of heater sealing be the medium heating chamber, the medium ascending pipe of extending out on medium heating chamber top.

After adopting said structure, because oil country tubular good coal burning and gas burning heating furnace mainly is to utilize the self-produced combustion gas of oil well casing to do the fuel heating, when can not satisfying, combustion gas utilizes coal-fired heating, the heat of burning is by medium in a lot of the fire tube heaters, efficiency of heating surface height, the burning dust is difficult for stopping up fire tube and flue, and medium is passed to spiral oil coil to heat crude oil is heated, and heats evenly.

Four, description of drawings:

Accompanying drawing is the structural representation of a kind of embodiment of the utility model.Among the figure: 1 flue adpting flange, 2 safety valves, 3 oil-pipings export 4 fire tubes, 5 oil-piping imports, 6 combustion gas interface, 7 deslagging fire doors, 8 combustion chambers 9 and light, add coal stove door 10 bodies of heater 11 liquid level gauges 12 medium filler ports 13 Pressure gauges.

Five, the specific embodiment:

With reference to accompanying drawing, the straight drum part of the body of heater 10 of this heating furnace is to roll with steel plate to be welded as vertical structure, and body of heater 10 internal upper parts are welded with spiral oil coil group and fire tube group, and the top is provided with exhaust opening flange 1, and the bottom is combustion chamber 8.Combustion chamber 8 is divided into two parts up and down by transversely arranged fire grate, and top is provided with coal-fired fire door 9 and combustion gas interface 6, and the bottom is provided with deslagging fire door 7, constitutes coal-fired, gas two-purpose combustion chamber.Vertical distribution many fire tubes 4 at the spiral oil coil middle part of body of heater 10 internal upper parts, and the upper and lower port of all fire tubes 4 connects with the exhaust opening of top and the combustion chamber of below respectively, forms passage of flame.The upper and lower port outer wall of all fire tubes 4 respectively by on lower clapboard and body of heater sealing be the medium heating chamber, extend out on medium heating chamber top medium ascending pipe 12 and Pressure gauge 13, safety valve 2 are drawn liquid level gauge 11 in medium heating chamber one side.Spiral oil coil outside is connected on crude exports 3 and the crude oil import 5.

During use, the oil pipeline that oil well is come is by being connected into and out of oil pipe mouth joint on valve and the body of heater, fill up heat transfer medium (superconducting fluid or water) from the medium ascending pipe, liquid level gauge valve-off behind the liquid level line, the tracheae line that the oil well casing mouth is come is connected with gas joint by valve.Open fire door and burnt gas valve and can carry out the combustion gas heating.Do not satisfy the demand as combustion gas, can open fire door and put into coal and light, adjust the air output on the ash gate, guarantee its normal combustion.Calory burning heating fire-tube group, fire tube group are medium in the heat heating furnace, and medium is passed to the oil coil group to heat again in the stove, and oil coil makes crude oil evenly by heating and viscosity reducing again crude oil in the heat heating tube, have reduced the pressure in the oil pipeline.When heating-up temperature surpassed the evaporating temperature of medium, produce can air pressure for medium in the body of heater, and pressure reaches the setting value of safety valve, and safety valve is opened automatically to drain and cuts out behind the air pressure, has guaranteed the safety of body of heater.Under the situation that sleeve pipe gas is arranged, make full use of the combustion gas heating like this, utilize coal-fired heating in the absence of sleeve pipe gas, both guaranteed the normal conveying of crude oil, reduced production cost again, energy-saving safe.
