Abstract
The utility model aims to provide a spraying dust removal device for gas drilling, which is simple in structure, firm, durable, convenient to replace and good in dust removal effect. The device comprises a main pipeline and spraying pipes. The outer edge of a connecting nut is welded on a round hole of the sidewall of the main pipeline; the spraying pipes are in threaded connection with the connecting nut; a back fastening nut fastens the backs of the spraying pipes; the bottom of each spraying pipe is provided with a slit; the surface of the slit is perpendicular to the axial direction of the main pipeline; the bottom of each spraying pipe is in a hemispherical shape. The spraying dust removal device is convenient to detach, little in resistance to gas flow, better in wear resistance and more durable. As the spherical bottom of each spraying pipe is provided with the slit, the spraying pipes are large in spraying angle; as two spraying pipes works simultaneously, the device is good in dust removal effect. As the shape of the slit ensures large spraying overflow area, channels are not easy to block, and spraying water in a blowdown pool can be recycled, so as to save water.
Description
Technical field
The utility model relates to a kind of dust arrester, relates in particular in a kind of gas drilling process, is used for the spraying dedusting device of sediment outflow pipe outlet.
Background technology
The gas drilling technology is meant in the drilling well that with gas as the power of the broken rock drilling technology of double as scouring media again, it comprises air drilling, inert gas drilling well, gas drilling etc.Gas drilling mainly contains and increases substantially rate of penetration, prolongs drilling life of bit, reduces drilling cost, reduces formation damage, reduces down hole problem (leakage or differential sticking etc.), is beneficial to advantages such as environmental protection.Therefore, gas drilling has been subjected to the great attention of various countries, and development is rapid, and range of application is more and more wider.
In the gas drilling process, the discharge capacity of desired gas generally 100 mark sides/minute more than, gas flow rate is very high, gas is taken drilling cuttings out of based on dust from the shaft bottom, the pipeline outlet opening forms serious airborne dust, to such an extent as to cause serious environmental to pollute, on the one hand, influence field personnel's operate as normal, and cause the infringement of air compressor machine, diesel engine; On the other hand, dust drops on crops around the well site, plant and the house owed by a citizen, and people's productive life is impacted, and particularly in the drilling process of deep-well and ultradeep well, institute's air demand is bigger, and the dust pollution that causes is more serious.What use at present mainly is that the solution that brake flap is sprayed water to the air-flow of sediment outflow pipe outlet simultaneously is set in the sediment outflow pipe, cause landwaste not discharge fully and block the sediment outflow pipe easily like this, constantly water spray causes the spill-over of pollution discharge pond water to go out easily in pollution discharge pond, causes once more and pollutes.Chinese patent publication number CN101070750A, in open day on November 14th, 2007, the name of utility model is called dust-removing device for gas drilling-well, this patent disclosure a kind of dust-removing device for gas drilling-well, utilize the shower that has sieve aperture that landwaste is wetting.Its weak point is this dust arrester sieve aperture spray water, and spray water can not cover whole sediment outflow pipe section, causes the part landwaste can not be wetting; In addition, the sieve aperture area of passage is big inadequately, and easy blocking channel is so the shower water in the pollution discharge pond can't recycle.
Summary of the invention
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of simple in structure, firm and durable, and it is convenient to change, the spraying dedusting device that dust removing effects is better.
For achieving the above object, the utility model adopts following design scheme: a kind of gas drilling comprises with spraying dedusting device: trunk line, shower.Attaching nut's outer rim is welded on the circular hole of trunk line sidewall, and shower is threaded with the attaching nut, and back tightening nut is tight with the shower back of the body; A slot is arranged at the shower bottom, and the slot face is axially vertical with trunk line.The shower bottom is a hemispherical.
The utility model has the advantages that: (1) shower is threaded easy installation and removal with the attaching nut.(2) shower bottom hemispherical dome structure is little to gas-flow resistance, more wear-resisting, firm and durable.(3) the shower spherical bottom has slot, and the spray angle is big, can work good dedusting effect simultaneously by a plurality of showers.(4) the slot form makes that the spray area of passage is big, is not easy blocking channel, so the shower water in the pollution discharge pond can recycle using water wisely.
Description of drawings
Fig. 1 is the schematic diagram of a kind of gas drilling of the utility model with spraying dedusting device.
1. showers among the figure, 2. back tightening nut, 3. attaching nut, 4. trunk line.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
In Fig. 1, attaching nut's 3 outer rims are welded on the circular hole of trunk line 1 sidewall, and shower 1 is threaded with attaching nut 3, and back tightening nut 2 is tight with shower 1 back of the body, and a slot is arranged at shower 1 bottom, and the slot face is axially vertical with trunk line 4.Shower 1 bottom is a hemispherical, 8 millimeters of slot width.Shower 1 has two, its main shaft angle 40 degree, and axial spacing is 1000 millimeters on trunk line 4.
In drilling process, gas-entrained landwaste dust is through the trunk line 4 of upstream row sandpipe to spraying dedusting device, meanwhile, pump sump, water enters two shower 1 endoporus respectively by flexible pipe branch, sprays into trunk line 4 by slot, and dust is wetting, be discharged to combustion cell through the downstream row sandpipe then, recirculated water in the combustion cell is then siphoned away by water pump, and water is recycled like this, finishes the task of dedusting.
Claims (2)
1. gas drilling spraying dedusting device, comprise trunk line (4), shower (1), it is characterized in that, attaching nut (3) outer rim is welded on the circular hole of trunk line (4) sidewall, and shower (1) is threaded with attaching nut (3), and back tightening nut (2) is tight with shower (1) back of the body, a slot is arranged at shower (1) bottom, and the slot face is axial vertical with trunk line (4).
2. a kind of gas drilling spraying dedusting device according to claim 1 is characterized in that the bottom of shower (1) is a hemispherical.
