Abstract

The utility model relates to an eddy flow soil discharging device, mainly solving the problem that the soil is not thoroughly discharged due to stop-production soil discharging of a sewage and dirty oil storage tank in the oil-field oil-extraction field. A setting tank (1) is connected with two water supply pipes (3) with valves and a discharge pipe (7) communicated with a sewage oil separator (2) and two arc water supply pipe headers (5) in relative circular distribution are set on the surface of a center reaction drum (6) in the setting tank and a plurality of soil washing pipes (4) with nozzles (9) are communicated with the arc water supply pipe headers (5) in tangent direction and brackets (1) are set between the setting tank (1) and the arc water supply pipe headers (5) and the water supply pipes (3) and the soil washing pipes (4). The device not only satisfies the soil discharging requirement of the common storage tank and thoroughly removes the soil when the mechanical soil discharging function is unavailable due to many pillars and other obstacle. The eddy flow soil discharging device has features of less investment, thorough soil discharge, simple operation and low labor intensity.

Description

The swirling flow mud discharging device

Technical field:

The utility model relates to the mud discharging device of sewage sump oil storage tank in the oil recovery field, oil field, particularly a kind of swirling flow mud discharging device.

Background technology:

The oil field is since dropping into exploitation, the continuous dissolved separation of clay in the subterranean strata pore structure and mineral matter thereof is also taken ground to extraction liquid, because the variation of ground system flow velocity is deposited on (separator, profit surge tank, settling tank, sewage recovery pond etc.) in all kinds of containers, its deposition and deposition velocity are the acceleration ascendant trend year by year, a large amount of silt particles is deposited in all kinds of containers of ground system, can not get rid of timely and effectively, suspension is vicious circle in system, suspension exceeds standard in the water, causes injecting the water quality variation.Existing sludge discharge way not only needs to stop production and carries out, and all exists than the large tracts of land dead angle, and part mud can't be discharged, and can not satisfy on-the-spot needs fully; Adopt artificial spoil disposal, 1 year stopping production spoil disposal once, though spoil disposal is thorough, long and labour intensity is big because of the off-time, also there are hidden danger in various degree in safety and environmental protection, cause some not spoil disposal of standing throughout the year.Because a large amount of mud exists in the jar, can not discharge effectively, the SS that settles down is dashed once more, and vicious circle in system causes the water quality variation, has a strong impact on ordinary production.

The utility model content:

The utility model is to overcome needs stopping production spoil disposal and the halfway problem of spoil disposal in the background technology, and provide a kind of swirling flow mud discharging device, this swirling flow mud discharging device need not stop production, not only satisfy common storage tank spoil disposal, and in storage tank, have a lot of columns can't use under the situation of mechanical dredge with other obstacles, still can thoroughly silt particle be got rid of.

The invention for solving the technical problem can reach by following technical solution: this swirling flow mud discharging device comprises settling tank, the sewage oil interceptor, feed pipe, two feed pipes of the outer tape splicing valve of settling tank and be communicated with the discharge pipeline of sewage oil interceptor, central reaction tube surface is equipped with the arc feed pipe header of two relative circular distribution in the settling tank, be the mud flushing tube that tangential direction is communicated with a plurality of band nozzles with the feed pipe header, between settling tank and arc feed pipe header, feed pipe, mud flushing tube bearing arranged.

Described mud flushing tube and arc feed pipe header are on same plane.

The dredging tube that connects in the described settling tank is communicated with the outer dredge pump of settling tank, and dredge pump connects the sewage oil interceptor, between dredging tube that connects in the settling tank and settling tank bearing is arranged.

The utility model is compared with the above-mentioned background technology can have following beneficial effect: this swirling flow mud discharging device can carry out spoil disposal to various vertical storage tanks, utilize water-aspirator pressure will filter back water and be transported to the swirling flow mud flushing tube through feed pipe, mud at the bottom of being deposited on jar broken up and by same direction rotation, silt is taken away in the swirling flow that produces, with outside the muddy water drain tank in the jar, solved plant equipment and can't directly scrape difficult problems such as mud again.Swirling flow mud discharging device small investment, easy for installation, spoil disposal is thorough, simple to operate, need not stop production, labour intensity is low.Make whole operation very laborsaving, improved operating efficiency.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is settling tank 1 internal views of the present utility model.

Among the figure: 1-settling tank, 2-sewage oil interceptor, 3-feed pipe, 4-mud flushing tube, 5-feed pipe header, 6-central reaction tube, 7-discharge pipeline, 8-dredge pump, 9-nozzle, 10-bearing, 11-dredging tube.

The specific embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

As shown in Figure 1, this swirling flow mud discharging device comprises settling tank 1, sewage oil interceptor 2, feed pipe 3, two feed pipes 3 of settling tank 1 outer tape splicing valve and be communicated with the discharge pipeline 7 of sewage oil interceptor 2, central reaction tube 6 surfaces are equipped with the 5 rounded distributions of 5, two arc feed pipes of two arc feed pipe headers header in the settling tank 1, are the mud flushing tube 4 that tangential direction is communicated with a plurality of band nozzles 9 with feed pipe header 5.

Described mud flushing tube 4 and arc feed pipe header 5 are on same plane, and mud flushing tube arranges that by tangential direction purpose is to reduce the pipe internal pressure loss, and the reduction mud flushing tube is to the resistance of swirling flow.

Accompanying drawing 2 is the internal view of the settling tank of this device, shown in accompanying drawing 2, be the mud flushing tube 4 of tangential direction tape splicing nozzle with feed pipe header 5, mud flushing tube 4 is welded on the feed pipe header 5, and arc feed pipe header 5 is welded on central reaction tube surface and is seated on the bearing 10 of settling tank 1.

In order to make a jar interior mud, the thorough emptying of muddy water, in settling tank 1, connect dredging tube 11, the dredge pump 8 that dredging tube 11 is communicated with outside the settling tank 1, dredge pump 8 connects the sewage oil interceptor.

Settling tank 1 and arc feed pipe header 5, feed pipe 3,

mud flushing tube

4,11 of dredging tubes have bearing 10, purpose is fixedly feed pipe 3, feed pipe header 5, mud flushing tube 4, dredging tube 11, bear the lateral impact power that swirling flow produces, stressed even, avoid tank body to be damaged.

The outer water-delivery pump pressure of this swirling flow mud discharging device utilization will be filtered back water and be transported to swirling flow mud flushing tube 4 through feed pipe 3 and feed pipe header 5, with water and the angled ejaculation of pot bottom, the mud at the bottom of the current of ejaculation will be deposited on jar breaks up and by same direction rotation by the nozzle on the swirling flow mud flushing tube 49.After the mud of pot bottom is broken up and is rotated, again mud valve is opened mud, muddy water in discharge pipeline 7 drain tanks, the muddy water that the is discharged from outer sewage oil interceptor 2 that enters the station, in order to make a jar interior mud, the thorough emptying of muddy water, can utilize dredge pump 8 to extract mud out jar outer sewage oil interceptor 2 of sending into again.

This swirling flow mud discharging device can thoroughly totally be removed mud, the silt in the various containers of using in oil field and the Chemical Manufacture, small investment, easy for installation, and spoil disposal is thorough, simple to operate, and labour intensity is low.
