Description

Technical Field

[0001] The utility model relates to the technical field of drilling and workover, and particularly relates to an atomizing dust removal device applicable to a dust discharge pipe for drilling and workover operations. Background Art

[0002] In oil and gas field drilling and workover operations, a large amount of drilling fluid and cementing fluid need to be prepared and used. The main preparation of drilling fluid and cementing fluid uses bulk materials such as bentonite, barite powder, and cement. Before the operation starts, the bulk materials are transported to the operation site by a workboat and conveyed into the storage tank on the platform through pneumatic conveying. During the preparation process of drilling fluid and cementing fluid, the bulk materials are also conveyed into the mud feeding tank and cement feeding tank through pneumatic conveying for slurry preparation. To achieve the purpose of pneumatic conveying, a breather pipe is connected to the top of the target storage tank or ash discharge tank, and the breather pipe is communicated with the atmosphere, so that the pressure in the receiving tank is as low as possible, and the conveyed bulk materials can be received. Since during the conveying process of bulk materials, compressed air is fully mixed with the bulk materials to form a "fluidized state", a large amount of bulk materials will be discharged into the atmosphere through the dust discharge pipe along with the compressed air, causing environmental pollution.

[0003] Currently, domestic oil and gas field drilling and workover operations mostly adopt measures such as filtration dust removal and closed dust removal, such as installing a filtration dust removal layer, adding a cyclone separator, and using a mother-daughter separator in cooperation with a purification pond for separation and purification. These methods have disadvantages such as incomplete dust removal, high equipment cost, difficult implementation, large workload, and inconvenient construction. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reasonably designed atomizing dust removal device applicable to a dust discharge pipe for drilling and workover operations, which can solve the above-mentioned defects in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: it includes a spray component, and a hoop component is connected to the spray component; the spray component includes a water guide pipe, several atomizing nozzles are arranged on the lower side of the water guide pipe, and a quick connector is arranged on the water guide pipe.

[0006] Preferably, the water guide pipe is an annular pipe, and several atomizing nozzles are evenly arranged on the lower side of the water guide pipe.

[0007] Preferably, the hoop component includes two groups of connection components symmetrically arranged on the water guide pipe. Each group of connection components includes a third hoop and a fourth hoop. The third hoop and the fourth hoop are sleeved on the water guide pipe, and the two ends of the third hoop and the fourth hoop are connected by bolts; the outer sides of the two third hoops are respectively connected with a first hoop and a second hoop through a connecting pipe, and the first hoop and the second hoop are connected by bolts.

[0008] Preferably, the first hoop, the second hoop, the third hoop and the fourth hoop are all arc-shaped ring structures. Both ends of the arc ring are bent outward to form an installation ear respectively, and bolt through holes for passing through connection bolts are formed on each installation ear. The bolt through holes at both ends of the first hoop and the second hoop are respectively connected by a first connection bolt and a first connection nut; the bolt through holes at both ends of the third hoop and the fourth hoop are respectively connected by a second connection bolt and a second connection nut.

[0019] See Figure 1 - Figure 2 As shown, it includes a spray component, and a ferrule component is connected to the spray component; the spray component includes a water guide pipe 3, several atomizing nozzles 4 are arranged on the lower side of the water guide pipe 3, a quick connector 2 is arranged on the water guide pipe 3, the water guide pipe 3 is an annular pipe, several atomizing nozzles 4 are evenly arranged on the lower side of the water guide pipe 3, the internal channel of the water guide pipe 3 is connected to the internal channels of the quick connector 2 and several atomizing nozzles 4, the atomizing nozzle 4 and the water guide pipe 3 are connected by threads, and a gasket 5 is arranged at the connection between the atomizing nozzle 4 and the water guide pipe 3;

[0020] The ferrule component includes two sets of connection components symmetrically arranged on the water guide pipe 3. Each set of connection components includes a third ferrule 18 and a fourth ferrule 19. The third ferrule 18 and the fourth ferrule 19 are sleeved on the water guide pipe 3. The outer sides of the two third ferrules 18 are respectively connected with a first ferrule 13 and a second ferrule 14 through a connecting pipe 15; the first ferrule 13, the second ferrule 14, the third ferrule 18 and the fourth ferrule 19 are all arc-shaped ring structures. The two ends of the arc ring are bent outwards to form an installation ear respectively, and bolt through holes for passing through connecting bolts are arranged on the installation ears. The bolt through holes at both ends of the first ferrule 13 and the second ferrule 14 are respectively connected by a first connecting bolt 11 and a first connecting nut 12; the bolt through holes at both ends of the third ferrule 18 and the fourth ferrule 19 are respectively connected by a second connecting bolt 16 and a second connecting nut 17.

[0021] The principle and usage process of the present utility model:

[0022] First, put the water guide pipe 3 part of this device outside the ash discharge pipe and move it to the position where it needs to be installed. Then, initially install the two sets of connection components on the water guide pipe 3 through several sets of second connecting bolts 16 and second connecting nuts 17. At the same time, adjust the angle of the connection components so that the first ferrule 13 and the second ferrule 14 are close to the ash discharge pipe. Install two sets of first connecting bolts 11 and first connecting nuts 12, and then tighten the first connecting bolts 11, the first connecting nuts 12, the second connecting bolts 16 and the second connecting nuts 17 respectively to complete the installation of the main components.

The water mist contacts and condenses and settles with the scattered materials discharged from the ash discharge pipe, so as to achieve the purpose of dust removal. At the same time, the water droplets sprayed out by adjacent atomizing nozzles 4 will collide with each other, further enhancing the atomization of water and achieving a better dust removal effect;

[0024] When recycling is needed, just loosen and remove the first connecting bolts 11, the first connecting nuts 12, the second connecting bolts 16 and the second connecting nuts 17 respectively, and then the remaining components can be easily removed.
