WITH

The invention relates to the mining industry and can be used to capture fracture products during drilling and thermal expansion of wells.

A known three-stage system for collecting destruction products adopted for a prototype comprising a sludge collector connected by a supply pipe to a dust collector in communication with a cyclone.

The disadvantage of this scheme is its low reliability and insufficient efficiency for collecting fine dust, as well as the large size of the system, which complicates its placement directly on the drilling rig.

The purpose of the invention is to increase the reliability and efficiency of the device during thermal drilling and expansion of wells.

The invention is illustrated in the drawings.

The device for collecting products of destruction during drilling consists of a sludge collector 1, which is coaxially located on the rod 2 of the drilling machine 3 and the lower end is installed above the well 4. The feed pipe 5 connects the sludge collector 1 with a dust collector 6, which is vertically arranged in the cyclone 7 and connected with the cavity of the cyclone 7. The cyclone 7 is equipped with a socket 8 with nozzles 9 mounted relative to the walls of the cyclone 7 with a gap decreasing to the bottom of the cyclone. Moreover, the nozzle nozzles 9 are located in the gap between the walls of the cyclone 7. Above the inlet of the dust separator 6 there are two chippers 10, while one chipper is installed with the formation of the inlet window 11 between the dust separator 6 and the inner cavity of the cyclone 7, and the second is installed opposite the inlet 11. trapping products devastating s |

during drilling, it is mounted inside the mast 12 of the drilling rig 3.

The device operates as follows.

During drilling, followed by fire expansion and purging of the wells, a dust and gas stream containing destruction products is transferred from wells 4 to a sludge collector 1, which provides a seal to the mouth 13 of a well 4, which prevents the dust and gas stream from escaping into the atmosphere, then from a sludge collector 1 through a supply pipe 5, the flow enters the dust separator 6. When moving along the dust separator 6, large particles of destruction products hit the chippers 10 and fall through the window 11 into the cyclone 7. The dust and dust stream purified from large particles walks into the socket 8 positioned in the cyclone 7. The funnel 8 is expandable in the direction of movement of the dust and gas flow, which provides a sharp decline

SUMMARY OF THE INVENTION A device for capturing products of destruction during drilling, including a sludge collector connected by a supply pipe to a dust separator in communication with a cyclone, characterized in that, in order to increase the reliability and efficiency of the device during thermal drilling and expansion of wells, the dust collector is vertically placed in the cyclone , and the cyclone is equipped with a bell with nozzles, dust and gas flow rates. As a result of this, dust particles fall out of the stream, and finely dispersed particles in the socket 8 are thrown under the action of centrifugal forces to the outer wall of the socket 8, towards the water flow ejected by the nozzles 9, whose nozzles are placed in the gap between the walls of the cyclone 7. This leads to intensive wetting fine particles with water, followed by their coagulation and the formation of conglomerates, which fall into cyclone 7 and settle on its bottom. The dust-free gas stream is discharged into atmosphere through a flue 14. The implementation of the device in the form of a cyclone with a bell, in which nozzles for spraying water are located, can significantly improve the reliability and efficiency of the device for trapping the products of destruction and reduce emissions of fine dust into the atmosphere. installed relative to the walls of the cyclone with a gap decreasing to the bottom of the cyclone, and two chippers located above the inlet of the dust separator, one of them being installed with the formation of the inlet window between the dust separator and the inner cavity of the cyclone, and the second installed opposite the inlet window, with the nozzle nozzles are placed in the gap between the bell and the walls of the cyclone.
