Abstract
The invention discloses a kind of reclaiming craft for condensate, which includes pump, collecting slots, and condenser. There sets two pipe lines at front of the value of pump, the upright U type exchanger on the pipe line is set on the collecting slots, the outer wall of U type exchanger places a unoccupied mouth, the two pipe lies connect with several spraying device on top of the U type exchanger, U type exchanger channel material is the condensate in pipe lines, the tube channel is circular water.
Description
Technical field
The present invention relates to a kind of process condensate and reclaim technology, be applicable to that process condensate recycles in the Chemical Manufacture after cooling.
Background technology
Produce a large amount of process condensates in the Chemical Manufacture, condensate liquid in urea production process derives from two parts, a part is the steam condensate after compressor turbine uses, it enter after by condenser 1 condensation feeder 2 by pump 3 through pipeline 11,12 are sent to out-of-bounds, another part is the steam condensate except that compressor, it does not converge to feeder 9 through any cooling means, temperature is up to 100 ℃, the loss that condensate liquid in feeder 9 is a large amount of because of evaporation causes, in order to reduce the temperature of liquid in the feeder 9, need to introduce the desalted water cooling from pipeline 8, by pump 10 through pipeline 11,12 are sent to out-of-bounds, have occurred on the one hand being sent to out-of-bounds and feeder 9 needs to introduce the phenomenon that the desalted waters cooling cause energy consumption to increase from pipeline 8 through condenser 1 condensed condensate liquid.
Summary of the invention
The objective of the invention is to utilize steam condensate after compressor turbine uses after condensation as the condensate liquid in the cold coal cooling feeder 9, the loss of minimizing high temperature condensate liquid.
Before the valve of the outlet line 11 of pump 3,10, two pipelines 5,6 are set, the vertical U type heat exchange of heat pipe 7 that is provided with on the pipeline 6 places on the above-mentioned feeder 9, the outer wall top of vertical U type heat exchange of heat pipe 7 is provided with drain 14, pipeline 5,6 connects vertical U type heat exchange of heat pipe 7 tops respectively, pipeline 5,6 connects several spray throwers of U type heat exchange of heat pipe 7 tops respectively, vertical U type heat exchange of heat pipe 7 shell side materials are the process condensate in the pipeline 5,6, and tube side is a recirculated water.
Process condensate liquid temp in the pipeline 5 is 38 ℃～43 ℃, and the process condensate liquid temp in the pipeline 6 is 82 ℃～100 ℃, and the temperature of recirculated water is 20 ℃～36 ℃.
1.3 tons of the per hour recyclable flash distillation condensate liquids of the present invention, make the temperature of condensate liquid in the feeder reduce to 75 ℃～80 ℃ by 100 ℃, reduce 0.8 ton/hour of flash distillation amount, 85 tons of the extraneous desalted waters of condensate liquid, simultaneously, because the steam condensate after compressor turbine uses is ceaselessly to be pooled in the feeder as a kind of low temperature spray cooling coal, make the condensate liquid of feeder obtain replenishing in time, avoided because of the find time instability brought to production of feeder.
Description of drawings
Fig. 1 is a process flow diagram
Be described further below in conjunction with accompanying drawing
The flash-off steam condensation absorption that condensate liquid in the pipeline 5,6 rises in U type heat exchange of heat pipe 7 cooling backs and feeder 9 makes the condensate temperature decline in feeder 9 grooves, a small amount of flash steam is sent to out-of-bounds by pipeline 11,12 through centrifugal pump 3,10 and mix cooled condensate liquid together by drain 14 emptying of heat exchanger shell-side top.
