Description
Technical field
The utility model relates to the high, medium and low temperature condensate liquid step reclaimers that chemical plant installations generates, and in particular to a kind of
Condensate liquid step recyclable device.
Background technique
Condensate liquid results from steam during heating and conveying, thus it not only water quality it is good and also contain big calorimetric
Amount, the high-temperature condensation water of condensate liquid recovery system recovered steam system discharge, can maximally utilise the heat of condensate liquid, save
Water is about used, fuel is saved.
Currently, condensate liquid recovery process is broadly divided into Recovery with Open-loop system and two kinds of closed-style recycling system.
1, Recovery with Open-loop system is that condensate liquid is recovered in header tank, during the recycling of condensate liquid and utilization, is returned
The open at one end on closed tube road is open to atmosphere to atmosphere, the i.e. header tank of condensate liquid.When the pressure of condensed water is lower, by pressing certainly not
When can reach recycling place, force feed is carried out to condensed water using high-temperature water pump.The advantages of this system is that equipment is simple, operation
Convenient, initial outlay is small；But system footprint area is big, resulting deficiency in economic performance, environmental pollution are larger, and due to condensation
Liquid is directly contacted with atmosphere, and the oxyty in condensed water improves, and is also easy to produce equipment corrosion.
2 closed-style recycling systems are condensed water header tank and all pipelines all in constant direct draught, and system is closing
's.Energy possessed by condensed water largely passes through certain reclaimer and is directly recovered in boiler in system, condensed water
Recovered temperature is only lost in pipe network cooling part, and due to closing, water quality is guaranteed, reduces the water process expense recycled into boiler
With.Its advantage is that condensing hot air furnace is good in economic efficiency, the long working life of equipment, but the initial outlay of system is relatively large,
It is inconvenient for operation.
The heat and power for how utilizing steam condensate to greatest extent, make high-grade steam condensate liquid and low-grade condensation
Liquid can be recycled properly, improve the effect of condensate liquid recycling, and easy to operate, reasonable, with low investment, be the skill of a urgent need to resolve
Art problem.
Summary of the invention
For the problems of the prior art, the utility model provides a kind of condensate liquid step recyclable device.
A kind of condensate liquid step recyclable device, it is characterised in that: described including high temperature condensate line and cryogenic condensation liquid pipe
The liquid outlet of high temperature condensate line is communicated with the inlet of the first flash tank, is gone out at the top of the expansion slot of the first flash tank setting
Mouth is communicated with after check valve with high-temperature steam pipe network by the road；The liquid outlet of first flash tank is flashed through drain valve and second
First inlet of tank communicates, and the liquid outlet of the cryogenic condensation liquid pipe is communicated with the second inlet of second flash tank,
The expansion slot top exit of the second flash tank setting is communicated with indoor heating system for steam ports, second flash tank
Leakage fluid dram divides two-way to be connected respectively with boiler feed, plate heat exchanger through condensate liquid booster pump.
Further are as follows: the liquid outlet and desalted water condensate liquid water tank of the plate heat exchanger or the inlet of desalted water mixed bed
It communicates.
Further are as follows: switch valve pipeline is parallel on the drain valve.
The utility model has the beneficial effects that the high and low temperature steam condensate generated to system combs, to high temperature is cold
Lime set carries out two-stage decompression expansion, and the low-pressure steam that first order expansion generates is for heat tracing, heat preservation；Second level expansion generates low
Press steam for heating, heating, life, cooling, rational technology, using effect are good.
