Abstract
The utility model discloses a flat-ground ignition device for gas well blowout. The utility model is characterized in that the flat-ground ignition device comprises an ignition tube which is fixed in a high-pressure gas combustion tube; the ignition tube is fixed through an anchor block; a row of ignition holes are evenly arranged on the ignition tube along the extending direction of the tube; the front ends of the ignition holes are connected with a blowout opening; and the tail ends of the ignition holes are connected with a gas source. The flat-ground ignition device can effectively solve the difficulty for ignition of site high-pressure blowout, and is simple and stable and reliable to operate, so that the safe blowout production for gas wells is ensured, and the investment cost and the actual cost are saved.
Description
Technical field
The utility model relates to the point-like device of high-pressure gas well, particularly a kind of gas well open flow level land firing device.
Background technology
Several kinds of modes below the general employing of at present general high-pressure gas well igniter:
The ever-burning flame igniting: drive a well moment, high velocity air, current are put out female fire easily, cause that natural gas spreads, and the danger of blast occurs, and very likely igniting is unsuccessful.
The fireworks igniting: igniting personnel's safe distance is the disadvantage of this sparking mode.
Electronic ignition: through connecting electric wire to the open flow mouth, ignition control switch is installed in janitor's room, closes a switch, the spark that utilizes high-tension current to produce is lighted fire.This igniter is applicable to the open flow torch mouth that the people is difficult for touching, as is installed in the level land, gets an electric shock easily when the people contacts.
The rail mounted igniter: this device uses track that igniter is delivered to the open flow mouth automatically, installs diesel oil in the igniter additional, utilizes the flame of diesel combustion ejection that fire is lighted.The place of this matching requirements ignition zone should be smooth, is fit to attachment rail, and this device uses more at test period.
More than these several kinds of modes because in the use at the scene, all have a lot of problems, therefore need a kind of novel igniter of design.
The utility model content
The utility model provides a kind of gas well open flow level land firing device, can solve the problem that occurs in the use at the scene, and through this structure ignition tube igniting, female fire is difficult for extinguishing, easy-to-operate, and fault rate is low.
A kind of gas well open flow level land firing device is characterized in that: comprise the ignition tube that is fixed in the high pressure gas combustion tube, ignition tube is fixed through anchor block, and ignition tube upper edge pipe bearing of trend is provided with the evenly distributed vent of a row; The front end of said vent connects the open flow mouth, the terminal source of the gas that connects.
The material of said ignition tube is a galvanized pipe.
The aperture of said vent is 2 millimeters, and the distance between two vents is 3 centimetres.
The end of said vent is processed into flat.Under the situation of equal gaseous-pressure, flow, can increase the flow velocity of air-flow in the igniter, and terminal galvanized pipe is upwarped about 15 degree.
The ignition tube of this firing device makes full use of the flowability of natural gas; The natural gas flow of burning is to the open flow mouth; Just can be with the natural gas igniting of open flow mouth ejection; Go out even the end of ignition tube is dashed by high velocity air, current, its flare that replenishes at the back also can be lighted fire, has overcome the unsuccessful difficult problem of igniting.
The beneficial effect of the utility model is following:
The utility model can effectively solve an on-the-spot high pressure open flow igniting difficult problem, and is simple to operate, reliable and stable, guaranteed the production of gas well safety open flow, practiced thrift cost of investment and practical cost.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is the use scheme of installation of the utility model
Wherein Reference numeral is: 1 open flow mouth, 2 ignition tubes, 3 anchor blocks, 4 high pressure gas combustion tubes, 5 vents.
The specific embodiment
Shown in Fig. 1-2, a kind of gas well open flow level land firing device comprises the ignition tube 2 that is fixed in the high pressure gas combustion tube 4, and ignition tube 2 is fixing through anchor block 3, and ignition tube 2 upper edge pipe bearing of trends are provided with the evenly distributed vent 5 of a row; The front end of said vent 5 connects the open flow mouth, the terminal source of the gas that connects.
The material of ignition tube 2 is the galvanized pipe of 1/2 inch (DN15mm).
Source of the gas is selected: production, gas for domestic use in standing.
The aperture of said vent 5 is 2 millimeters, and the distance between two vents 5 is 3 centimetres.
The end of said vent 5 is processed into flat.Under the situation of equal gaseous-pressure, flow, can increase the flow velocity of air-flow in the igniter, and terminal galvanized pipe is upwarped about 15 degree.
The ignition tube 2 of this firing device makes full use of the flowability of natural gas; The natural gas flow of burning is to the open flow mouth; Just can be with the natural gas igniting of open flow mouth ejection; Go out even the end of ignition tube 2 is dashed by high velocity air, current, its flare that replenishes at the back also can be lighted fire, has overcome the unsuccessful difficult problem of igniting.
In use, at first regulate in the station produce, gas for domestic use pressure is at 0.1-0.2MPa, opens gas source switch and lights, and utilizes the flare of this firing device sustained combustion that high velocity air is lighted.
The economic benefit of the utility model can be that example is calculated with certain well; What use is that 1/2 inch galvanized pipe is made ignition tube 2, about 250 meters of length, 8 yuan every meter; Investment is only about 2000 yuan; Compare with electronic ignition device is installed, every cover will be practiced thrift cost at about 150,000 yuan, therefore practice thrift very much cost of investment and use cost.
