Abstract
The utility model relates to a special flame arrester for drilling fuel gas discharge. In order to overcome the shortage that an ignition device of the fuel gas discharged in oil drilling at present is provided with no flame arrester, flame arresting nets (5) used by the utility model are sieve nets having six to twelve layers and eighty meshes; separation distance among the flame arresting nets (5) is between 10 mm and 20 mm; the ratio of the diameter of each flame arresting net (5) and the through diameter of the small end of a connecting flange (11) is 2: 2.5; both ends of each flame arresting net (5) are provided with protective nets (6) which are the sieve nets respectively having forty meshes. The special flame arrester for drilling fuel gas discharge of the utility model has the properties of explosion protection, fire protection and corrosion prevention; the structure is compact, and the installation is convenient; a net core can be conveniently replaced and cleaned; combustion flame can be effectively prevented from tempering, and safety production can be ensured.
Description
Technical field
The utility model relates to a kind of spark arrester, particularly relates to a kind of drilling well combustible gas and discharges special-purpose spark arrester.
Background technology
The drilling fluid that carries earth cuttings in the oil drilling process returns out well head, and the drilling fluid that returns out well head contains drilling mud, oil, water, landwaste and combustible gas etc. usually.The drilling fluid that returns out at first separates through gas-liquid separator, becomes mist and mixing material two parts after the separation.For fear of environment is polluted, the mist after the separation is emitted by pipe special (being commonly referred to the burning pipeline), and the fuel gas that the burning pipeline is discharged is lighted, and the mixing material after the separation is discharged in the pollution discharge pond and deals with in addition.Combustible gas can be lighted by the special ignition device, as Chinese utility application (application number 02237613.5) solar energy automatic ignition device.Because the incoherence of the combustible gas that gives off is easy to generate tempering when the combustible gas burning of lighting is interrupted, in a single day tempering enters gas-liquid separator and will set off an explosion.At present, a lot of industries all have special-purpose spark arrester, as the safe fire retardant device of Chinese utility model patent (ZL92215681.6) household low pressure petroleum liquified gas back-fire relief explosion-proof valve, a kind of hydrogen-oxygen welding-cutting tool of Chinese utility model patent (ZL96244226.7), fire prevention that Chinese utility model patent (ZL95233357.0) fire-retardant breather valve is mainly used in oil storage tank and pressure regulation etc., but be not applicable to the special-purpose spark arrester of combustible gas discharging burning in the oil drilling.
The utility model content
The purpose of this utility model is not have the deficiency of spark arrester in order to overcome the combustible gas firing device that discharges in the present oil drilling, provides a kind of drilling well combustible gas simple in structure, that be convenient to install to discharge special-purpose spark arrester.
In order to achieve the above object, the back-fire relief net that the utility model drilling well combustible gas discharges special-purpose spark arrester is 6～12 layers, 80 purpose screen clothes, and the spacing between the back-fire relief net is 10～20mm; The ratio of the diameter of back-fire relief net and connecting flange small end latus rectum is 2～2.5; Back-fire relief net two ends are equipped with catch net, and catch net is 40 purpose screen clothes.
The utility model drilling well combustible gas discharges special-purpose spark arrester and has explosion-proof, fire prevention, antiseptic property, and the spark arrester compact conformation is convenient to install, and is convenient to the replacing and the cleaning of web-roll core, can effectively prevent the combustion flame tempering, guarantees safety in production.
Description of drawings
Fig. 1 is that the utility model drilling well combustible gas discharges special-purpose spark arrester structural representation.
Among the figure: 1. fire-retardant core, 2. retainer ring, 3. retainer ring, 4. retainer ring, 5. back-fire relief net, 6. catch net, 7. taper seat, 8. bolt, 9. housing, 10. bolt, 11. connecting flanges.
The specific embodiment
With reference to accompanying drawing, back-fire relief net 5 is that 6～12 layers, 80 orders, steel wire diameter are the screen cloth of 0.125mm, the best when back-fire relief net 5 is 8 layers, and the material of screen cloth is preferably selected stainless steel for use; Spacing between the screen cloth is 10～20mm, and the spacing of selecting is about 15mm usually.Back-fire relief net 5 two ends are equipped with catch net 6, can prevent to damage back-fire relief net 5 because of gas erosion or object fall, and it is the stainless steel mesh of 0.224mm that catch net 6 is selected 40 orders, steel wire diameter usually for use.Between the back-fire relief net 5, between back-fire relief net 5 and the catch net 6 retainer ring 2, retainer ring 3, retainer ring 4 are installed; The cylindrical that retainer ring 2, retainer ring 3, retainer ring 4 contact with back-fire relief net 5, catch net 6 is the taper seat 7 that cooperatively interacts; back-fire relief net 5, catch net 6 are tightened screen cloth fixing by the taper seat that cooperatively interacts; in order to prevent that retainer ring from cutting up screen cloth when the fixed grit, adopt aluminum alloy materials to make retainer ring usually.Retainer ring is fixed as fire-retardant core 1 with bolt 8 with back-fire relief net 5, catch net 6, retainer ring 2, retainer ring 3, retainer ring 4 after screen cloth is fixed.
Fire-retardant core 1 is installed in the housing 9 of spark arrester, connecting flange 11 and housing 9 is connected into one, just formed the drilling well combustible gas and discharged special-purpose spark arrester with bolt 10.
Because the 1 pair of gas from pipeline of fire-retardant core in the spark arrester can not have any resistance, suppress phenomenon, fire-retardant core 1 should have enough big area of passage, so the diameter of fire-retardant core 1 need should satisfy formula greater than the latus rectum of discharging combustible exhaust gas pipeline:
D＝(2～2.5)d
In the formula: D---the diameter of fire-retardant core 5
D---connecting flange 11 small end latus rectums
Owing to burn for a long time in the combustible gas exit, temperature is very high near the outlet, and spark arrester should be installed in apart from port 10m with position far away.
Selecting for use of back-fire relief net 5, catch net 6 used screen clothes should meet GB/T11650-89 " drilling fluid vibrating sieve crochet screen cloth " requirement in the utility model.
