Background technology
The discharge of steam-heating apparatus condensate is the important step of system operation.Process system engineering design technology is advised
It is fixed：For separate unit, single group firing equipment, the condensate produced after steam heat release enters drain valve discharge；To separate unit firing equipment
Two groups of heat exchangers are installed, should be according to the equipped drain valve of heat exchanger sum if heat exchanger capacity is not waited.It is existing as shown in Figure 5, Figure 6
In real operating mode, unit platform is numerous using the equipment of two groups of heat exchanger parallel connection discharge condensates.Wherein, condensate shown in Fig. 6 is in parallel
Export structure has two：1. the outlet pipeline length of heat exchanger 1 is more than heat exchanger 2, and drainpipe resistance is more than heat exchanger 2；②
Because condensate enters drainpipe in outflow heat exchanger with vapour-liquid two-phase stream mode, the discharge pipe line of heat exchanger 1 is in hydrophobic process
Continue heat release, the yield of condensate can be more than the condensing capacity of heat exchanger 2.The presence of above-mentioned two problems causes heat exchanger 2
Condensate short circuit quick drain, causes water in the die cavity of heat exchanger 1, causes the overall heat release effect of the uneven influence of system heat release
Rate.Shown in accompanying drawing 7, the heart channel of Hang-Shaoyin threeway parallel connection water outlet in spacing of two groups of heat exchanger outlet pipes.This structure has two：1. because
Current direction is condensed to top, is directly affected the basic law of " condensate answers following current to discharge ", is caused impeded drainage；2. when two groups of heat exchange
When device meets heat release area equation, but certain can be then caused to organize impeded drainage because production, manufacture, installation etc. have undesirable element.This
When will cause two groups of heat exchanger leaving water temperatures.If the two-way condensate that temperature is not waited confluxes at threeway, again result in
The condensate of higher temperature prevents the condensate discharge of lower temperature in threeway exit.It is this HG/ in view of there is above mentioned problem
T20570-95 (People's Republic of China's professional standard " process system engineering design technology is provided ") P543 5.0.2 regulation：
" many gas utilization units can not share a drain valve, to prevent short-circuit draining ".If every group of heat exchanger installs a drain valve, not only
Equipment investment cost is high, more importantly to install a drain valve more, then one steam leakage point of many increases of meeting, causes steam heat
The loss of energy is wasted.
Currently, two urgently to be resolved hurrily or two groups gas utilization unit condensate parallel connection discharges of steam-heating apparatus cause heat exchanger to be put
Hot non-uniform temperature, the problem that influence exothermal efficiency, influence are normally produced.
