Abstract

The utility model discloses a two-stage vacuum system of a urea device. The system comprises a two-stage vacuum concentrator, wherein a vacuuming exhaust pipe is arranged at the top of the two-stage vacuum concentrator and sequentially connected with a jet pump and a three-way valve; the three-way valve is connected with a low-pressure washing water pipe. The two-stage vacuum system is easy to wash and free of blind areas and can be used for preventing crystallization of equipment and improving long-term operation and safety of the equipment so that the urea is guaranteed to be evaporated and concentrated more fully in V-15 equipment and finally the product quality of the urea is improved.

Description

Two sections of vacuum systems of urea plant
Technical field
The utility model relates to a kind of production equipment of urea plant, relates in particular to two sections of vacuum systems of a kind of urea plant.
Background technology
Urea (CO (NH 2) 2) belonging to organic compound, pure urea is colourless, tasteless aciculiform and prismatic four jiaos of crystal.Main application: the one, as agricultural concentrated fertilizer, the 2nd, can be used as the auxiliary fodder of ruminant, the 3rd, as the raw material of industry and preparation, be widely used in plastics, paint, adhesive, medicine, coating, chemical fibre, agricultural chemicals, papermaking, weaving, in the industry such as process hides.Carry in urea production process at ammonia at present, it is all to take (V-15) side to give vent to anger that two sections of vacuum systems vacuumize.The vacuum height of two sections of vacuum systems affects the quality of urea product.
In prior art, it is all the design of taking (V-15) side to give vent to anger that two sections of vacuum systems vacuumize, its shortcoming be easily to cause contracting two urine block trunnion, affect the vacuum of V-15 equipment, there is blind area in flushing, is not easy to rinse well, the equipment V-15 inwall crystallization making.Within general 6 months, will clear up once, cleaning timer will stop, and causes unnecessary waste, consumes manpower when cleaning, and material resources also exist very large potential safety hazard, damage equipment in scale removal process.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of urea plant two sections of vacuum systems, because blocking trunnion, contracting two urinary crystals do not affect vacuum, can reduce the crystallization of V-15 device interior, can there is not flushing blind area by cleaning down in flushing water, raising equipment long-play, reduces cleaning equipment number of times.
The technical solution of the utility model is as follows:
Two sections of vacuum systems of urea plant, comprise two sections of vacuum concentrators, the top of described two sections of vacuum concentrators is provided with vacuumizing and exhausting pipe, on described vacuumizing and exhausting pipe, is connected to successively jet pump and three-way valve, is connected with low-pressure washing water pipe on described three-way valve.
The utility model can be controlled the vacuum in V-15 equipment effectively, solve two urine that contract in original design and easily blocked trunnion, give vent to anger to vacuumize and be not easy to cause contracting two urine in device interior crystallization in utility model top, easily rinse, there is not blind area, prevented equipment crystallization, improved long-play and the security of equipment, thereby ensure urea more fully evaporation and concentrated in V-15 equipment, finally improved the product quality of urea.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to accompanying drawing, two sections of vacuum systems of urea plant, comprise two sections of vacuum concentrators 1, and the top of described two sections of vacuum concentrators 1 is provided with vacuumizing and exhausting pipe 2, on described vacuumizing and exhausting pipe 2, be connected to successively jet pump 3 and three-way valve, on described three-way valve, be connected with low-pressure washing water pipe.

Claims (1)

1. two sections of vacuum systems of urea plant, it is characterized in that: comprise two sections of vacuum concentrators, the top of described two sections of vacuum concentrators is provided with vacuumizing and exhausting pipe, on described vacuumizing and exhausting pipe, is connected to successively jet pump and three-way valve, is connected with low-pressure washing water pipe on described three-way valve.
