Abstract

An upright coil pipe water jacket furnace relates to a crude oil migration heating device, comprising an upright water jacket furnace body and heightens the furnace body and the chimney, wherein the lower part of the chimney is provided with a smoke collection chamber, the flue is inclined, a crude oil pipeline in the furnace body adopts a coil pipe structure coiled outside the flue, of which the lower end is a crude oil pipeline inlet and the upper end is a crude oil pipeline outlet, the lower end of the flue is connected with an arched furnace roof, the inner side of the furnace body under the arched furnace roof is arranged with a fireproof liner, the fireproof liner and the fire grate form a combustion area, and the bottom of the furnace body is provided with a fire grate. The furnace body has a short flue, thus is easy to clean dust and avoid water accumulation, and the hearth can avoid the retention of natural gas, to obtain safe ignition. The upright coil pipe water jacket furnace has the advantages of high exhaustion force, strong bearing ability and abundant combustion and the ability for improving crude oil heat exchange effect.

Description

Vertical coil pipe water jacket furnace

Technical field

The utility model relates to a kind of oil migration firing equipment.

Background technology

In the migration process of well mouth of oil well production fluid, because crude oil property, line pressure, reasons such as temperature, cause the event of running affairs with fixed attention easily, for eliminating the influence that the event of running affairs with fixed attention brings to ordinary production, the major technique measure of Oilfield using at present is to adopt horizontal water jacket furnace, the oil well single well pipeline is heated, though adopt horizontal water jacket furnace can play certain good effect, but still have following problem and shortage: 1, it is insufficient to burn, because flue is longer, not easy-to-clean ash, and chimney is lower, and suction force is little, it is impure to add sleeve pipe gas, moisture, easily cause the burner hearth corrosion, combustion instability.2, the boiler tube design is unreasonable, and heat exchange efficiency is low, and present horizontal water jacket furnace adopts straight tube " " inflection design, and crude oil production fluid amount is low, easily causes laminar flow, and the heat exchange effect is relatively poor.3, bearing capacity is low, and the inner weld bond of body of heater is more, 180 degree revolutions, and stress is concentrated, and bearing capacity is low.4, poor safety performance, owing to the Proper Design reason, horizontal stove is easy to stop working, and causes to have a large amount of natural gases in the burner hearth, easily causes the tempering casualty accident when lighting a fire once more.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of vertical coil pipe water jacket furnace, and unreasonable to solve prior art body of heater, crude oil pipeline and flue design, it is insufficient to burn, and bearing capacity is low, problems such as poor safety performance.

The technical scheme that its technical problem that solves the utility model adopts is to adopt vertical water jacket furnace, body of heater and chimney are increased, fume collecting chamber is established in its chimney bottom, flue adopts the italic setting, crude oil pipeline is the coiled structure in the body of heater, hover above the flue outside, its lower end is the crude oil pipeline import, and the upper end is the crude oil pipeline outlet; The flue lower end connects the arch furnace roof, and the following furnace body inside of arch furnace roof is provided with refractory liner, forms the combustion zone between fire grate, and bottom of furnace body is provided with fire grate.

Adopting good effect of the present utility model is that vertical coil pipe water jacket furnace is less at associated gas, can satisfy the heating needs of petroleum pipeline under the impure situation; It is big to have draft, and sufficient combustion makes advantages such as crude oil heat exchange better effects if.Crude oil pipeline adopts coil arrangement in the body of heater, has increased the contact area of crude oil and coil pipe, makes heat exchange more abundant; Improved the bearing capacity and the safety operation performance of pipeline, the Proper Design flue is short, easy-to-clean ash, and water should not retain natural gas in the burner hearth, the some fire safety.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structural representation of the present utility model;

1 chimney, 2 fume collecting chamber, the outlet of 3 crude oil pipelines, 4 crude oil pipelines, 5 refractory liners, 6 fire grates, 7 crude oil pipeline imports, 8 arch furnace roofs, 9 flues, 10 bodies of heater among the figure.

The specific embodiment

The utility model mainly is made up of chimney, fume collecting chamber, coil pipe, refractory liner, and fume collecting chamber (2) is established in its chimney (1) bottom, has increased the height of chimney, and fume collecting chamber places body of heater (10) top.Crude oil pipeline (4) adopts the coiled structure in the body of heater, hover above flue (9) outside, its lower end is crude oil pipeline import (7), the upper end is crude oil pipeline outlet (3), crude oil pipeline (4) adopts seamless boiler tube to make, and the coil pipe monoblock type is provided with, and has improved bearing capacity and safety operation performance greatly.Increase heat exchange area; Body of heater inner flue (9) adopts the italic setting, and pipe is made.Flue (9) lower end connects arch furnace roof (8), and arch furnace roof (8) is provided with refractory liner (5) with lower furnace body (10) inboard, forms the combustion zone between fire grate (6), and body of heater (10) bottom is provided with fire grate (6).

Claims

1, a kind of vertical coil pipe water jacket furnace, mainly form by chimney, fume collecting chamber, coil pipe, refractory liner, it is characterized in that adopting vertical water jacket furnace, body of heater and chimney are increased, and fume collecting chamber is established in its chimney bottom, and flue adopts the italic setting, crude oil pipeline is the coiled structure in the body of heater, hover above the flue outside, its lower end is the crude oil pipeline import, and the upper end is the crude oil pipeline outlet; The flue lower end connects the arch furnace roof, and the following furnace body inside of arch furnace roof is provided with refractory liner, forms the combustion zone between fire grate, and bottom of furnace body is provided with fire grate.
