Abstract
The utility model relates to a material recovery system for petrochemical unit pumps. The problem that fire blast and personnel poisoning incidents happen easily due to the fact that materials in existing pumps are discharged into open buckets in the prior art is mainly solved. The material recovery system is characterized in that emptying valves of outlet pipelines of a pump A (1), a pump B (2) and a pump C (3) are connected with a nitrogen purging main pipeline (4) through pipelines, inlet pipelines of the pump A (1), the pump B (2) and the pump C (3) are respectively connected with low emptying valves (7), seamless steel pipes identical in pipe diameter are assembled on connectors of the three low emptying valves (7) and connected to a material extraction pipeline (5), the material extraction pipeline (5) is connected with an airtight blowdown vessel (6) with a vessel bottom extraction pump, and a valve is connected on the material extraction pipeline (5). The material recovery system for the petrochemical unit pumps can recover materials safely, environmental pollution is reduced, and security risk is eliminated.
Description
Technical field
The utility model relates to a kind of material recovering system in petrochemical industry, particularly a kind of petrochemical plant pump material recovering system.
Background technique
Before the maintenance of petrochemical plant pump, the material in pump be drawn off to barrelling, and then totally keep in repair with nitrogen blowing.Conventionally be all to receive on the low spot discharging valve of pumping intake piping line with an end of sebific duct, the other end is put in bucket, accesses nitrogen material in pump is purged in bucket on pump discharge atmospheric valve.In petrochemical plant, major part is inflammable and explosive, poisonous and hazardous material, if packed in open drum, inflammable and explosive, poisonous and hazardous material is easy to evaporate in environment, fires, personnel's poisoning, and material recycle is also very difficult.
Summary of the invention
Technical problem to be solved in the utility model be overcome material in the existing pump existing in background technique be discharged in open drum easily fire, the problem of personnel's poisoning, and provide a kind of petrochemical plant pump material recovering system, this petrochemical plant pump material recovering system, can safe retrieving material, reduce environmental pollution, eliminated security risk.
The invention for solving the technical problem can reach by following technical solution: this petrochemical plant pump material recovering system, comprise pump A, pump B, pump C, pump A, pump B, pump C connect respectively suction line and outlet line, and the atmospheric valve of described pump A, pump B, pump C outlet line is connected with nitrogen blowing main pipe line by pipeline respectively; Described pump A, pump B, pump C suction line are connected to respectively low spot discharging valve, and the seamless steel pipe that assembles respectively identical caliber on 3 discharging valve joints is connected to material and draws back pipeline, material draw back pipeline and have tank at the bottom of the Closed Drain tank of extraction pump be connected; Material is drawn back and on pipeline, is connected to valve.
The utility model is compared and can be had following beneficial effect with above-mentioned background technology: this petrochemical plant pump material recovering system is owing to adopting above-mentioned flow process, streams closed discharge in pump can be recycled, be difficult for occurring security incident, reduce environmental pollution, eliminated security risk.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-pump A, 2-pump B, 3-pump C, 4-nitrogen blowing main pipe line, 5-material is drawn back pipeline, 6-Closed Drain tank, 7-discharging valve.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this petrochemical plant pump material recovering system, comprises pump A1, pump B2, pump C3, pump A1, pump B2, pump C3 connect respectively suction line and outlet line, and the atmospheric valve of pump A1, pump B2, pump C3 outlet line is connected with nitrogen blowing main pipe line 4 by pipeline respectively; Described pump pump A1, pump B2, pump C3 suction line are connected to respectively low spot discharging valve 7, the seamless steel pipe that assembles respectively identical caliber on 3 discharging valve 7 joints is connected to material and draws back pipeline 5, material draw back pipeline 5 and have tank at the bottom of the Closed Drain tank 6 of extraction pump be connected; Material is drawn back on pipeline 5 and is connected to valve.
This petrochemical plant pump material recovering system, in grand celebration, carbon four segregating unit pump discharge of materials reclaiming systems have been implemented to the present invention, the seamless steel pipe of joining identical caliber on the low spot discharging valve joint of pump intake pipeline is to the Closed Drain tank of extraction pump at the bottom of having tank, on pump discharge atmospheric valve, access nitrogen material in pump is purged in tank, save bit by bit and a certain amount ofly with pump at the bottom of tank, draw back system recycling again.Realized the streams closed discharge in pump, recycled, eliminated security risk, device normal operation has reached invention effect.
