Description

A kind of blowdown collection conveying device

Technical field

The utility model is related to petroleum chemical industries, and conveying device is collected more particularly, to a kind of blowdown.

Background technology

The system of setting blowdown in need in the main production unit of petroleum chemical industry and auxiliary unit, such as：Sump oil, alkali Liquid, amine liquid and other media.More medium can be transferred in time by pipe special in tower and container, but tower, container bottom and Can still there be a small amount of medium in pipeline, the pump of another ground configuration, due to elevation, blowdown is difficult.In unit often It is provided with the dendritic drainage of a set of or a few sets, larger buried tank is provided in the end of the drainage, is set around tank body Concrete building enclosure is set, corresponding elevator pump is set on tank, medium is promoted to storage tank or other receiving facilities through the pump.

The equipment such as tower, container, pump are more in unit, and blowdown point is more, and buried pipeline system is more complex, and petrochemical industry is each Production unit considers the measures such as emphasis antiseepage again, needs to find leak point in time and avoids ring caused by underground piping leakage It pollutes in border.

Since buried pipeline is more, pipeline interconnects again, when wherein a certain buried pipeline leakage needs to purge and cut When disconnected, need multiple spot while handling, in addition due to purging pressure, medium is easily mutually gone here and there, and can not thoroughly be located to the pipeline Reason is clean.

Specific implementation mode

The utility model is described in detail with reference to specific embodiment.Following embodiment will be helpful to this field Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made. These belong to the scope of protection of the utility model.

Embodiment

A kind of blowdown collection conveying device, structure is as shown in Figs 1-4, is locally embedded in underground or close proximity to ground arrangement, office Portion need to be arranged when being embedded in underground installation in the concrete structure for taking emphasis seepage control measure, between the device and concrete structure Sand need to be filled, as shown in fig. 1.Head cover detachable connection is on the ontology of device, cleaning convenient to overhaul, and on the top of device Handle 10 can also be arranged in portion.

Blowdown import N1 pick pump etc. other sewage draining exits for needing waste removal equipment, height and position can be according to pump sewage draining exits Location-appropriate adjusts, blowdown inlet valve 1 on the blowdown inlet pipeline between blowdown import N1 and the device.Ozzle N2 connects pressure gauge valve 2, pressure gauge valve 2 is followed by pressure gauge 11, the range of pressure gauge 11 according to steam or nitrogen and need to receive blowdown medium reservoirs or its It the height of its facility and is determined apart from comprehensive.The first steam transfer valve 3, exhaust and inspection are connected on the pipeline of steam inlet N2 connections Valve 4, the second steam transfer valve 5 are looked into, wherein exhaust and test valve 4 can play the role of exhaust and inlet system inspection, is come from The steam or nitrogen of pipe bridge are entered by steam inlet N2 in device by jet chimney, the waste pipe of waste N4 connections Be provided with the first blowdown outlet valve 6 and the second blowdown outlet valve 8 on road, the first blowdown outlet valve 6 and the second blowdown outlet valve 8 it Between be additionally provided with check-valves 9, emptying and test valve 7 are connected between check-valves 9 and the second blowdown outlet valve 8, is gone out for blowdown Mouth and outlet system inspection, emptying and the outlet of test valve 7 can be with regard to proximity funnel, sewage ditch or other provisional admission facilities.

In addition, the above-mentioned valve used is ball valve or gate valve, increase the pipe fittings such as corresponding articulation, elbow on pipeline, Valve and pipe fitting are determined according to the pressure of steam or nitrogen.The entrance of waste pipeline is connected with guiding trestle S1, one end Support is connected on the inner wall of device, and the other end is connect with waste pipeline, dismounting when both can be convenient to overhaul, also can be effective The vibrations and displacement of pipeline when reducing the purgings such as pressure conveying or steam.

When collecting gravity stream blowdown medium：Close the first blowdown outlet valve 6, the second blowdown outlet valve 8, emptying and test valve 7 and the second steam transfer valve 5, it opens pressure gauge valve 2, the first steam transfer valve 3, exhaust and test valve 4 and is communicated with air, finally Open blowdown inlet valve 1, from pump and the blowdown medium of equipment can gravity flow in the device.

When pressure current conveys blowdown medium, blowdown inlet valve 1, exhaust and test valve 4 and emptying and test valve 7 are closed, is beaten Pressure gauge valve 2, the second blowdown outlet valve 8, the first blowdown outlet valve 6, the first steam transfer valve 3 and the second steam transfer valve 5 are opened, By in device sump oil or other receiving facilities such as the land storage tank that is delivered in tank area or device of other pressure mediums in.

After conveying purging, the second steam transfer valve 5, the first steam transfer valve 3, the first blowdown outlet valve 6, second row are closed Dirty outlet valve 8 and exhaust and test valve 4, open whether emptying and 7 inspection system of test valve have mutually string phenomenon (the second waste The whether interior leakage of valve 8), after waiting for that pressure gauge no pressure, emptying and test valve 7 are flowed out without medium, opens the first steam transfer valve 3, arranges Gas and test valve 4 and blowdown inlet valve 1 restore to collection gravity stream blowdown state.

The device scope of application and it should be noted problem：A large amount of blowdown media such as tower and container need to pass through proprietary line treatment It is delivered to storage tank or other receiving facilities is not suitable for toxicity when the device is only applicable to a small amount of blowdowns such as later stage or pump yet And the stronger medium blowdown of volatility, it otherwise needs to increase corresponding safety devices.

The device can be used alone, also can multiple sets of parallel use.The existing petrochemical industry in the alternative part of the utility model Drainage " visualization " is effectively solved the environmental pollution thing caused by buried pipeline leaks by the buried pollution discharge system of industry Therefore it is reluctant after can also solving the problems, such as buried pipeline leakage.

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, This has no effect on the substantive content of the utility model.
