Description
Technical field
The invention belongs to the steam condensate exhaust unit of steam thermal system, more particularly, to a kind of steam condensate normal pressure
Exhaust system unit.
Background technology
The key link of condensate is produced in induction system in the normal steam thermal system running（Steam pipe system）And use
Vapour terminal（Firing equipment）Condensate produced by it is discharged it by being equipped with dissimilar, different displacements drain valve, with
The normal operation of guarantee system.
Now using equipped drain valve, three types are had according to the Starting mode playing closing member：First, controlled by liquid level change
Mechanical type；2nd, the heat static force type being driven by condensing water temperature change；3rd, the heat power type being driven by vapour-liquid dynamic change.Above-mentioned
The great advantage of three types drain valve is, can automatically control discharge to the condensate of variable relatively, has draining resistance vapour function.
But because there being leakage vapour phenomenon and service life is short, cause some vapor thermal waste during its draining, this problem insider reaches
Become common recognition, drain valve is classified as the easy-consumed goods of low value.The energy consumption issues discharging condensed water in high temperature for drain valve have caused correlation
Expert and the attention of departments of government.Developed country takes hermetic reclaim to condensate or step recycles in the world,
But fail fundamentally to solve the heat energy system waste problem that drain valve discharge condensed water in high temperature leads to, tracing sth. to its source is because hydrophobic
Valve does not possess the function that adjustment controls temperature at discharging condensate.The use temperature of steam thermal system all more than 100 DEG C, the product of condensate
Raw temperature is same, such as steam-supplying system, and when pressure of steam supply is for 1.0Mpa, its vapor (steam) temperature is 184.13 DEG C, condensate
Formation temperature is equal thereto, and pressure is equal.As its technological temperature of vulcanization of rubber equipment is 160-164 DEG C, the generation of its condensate
Temperature is not less than 160 DEG C.And do not talk the waste of steam that during drain valve draining, leakage vapour causes, only for discharge condensed water in high temperature,
When condensed water in high temperature with pressure can produce secondary vaporizing after drain valve discharge at once, hydraulic pressure is down to atmospheric pressure state, high sensible heat in water
418kj/kg is down to by height.When condensing water pressure in 1.0Mpa, when temperature is 184.13 DEG C, in its water, sensible heat is 781.6kj/
kg.When in water after drain valve is discharged, sensible heat is down to 418kj/kg, its secondary vaporizing value is 18%.That is, the condensate of 1kg just has
0.18kg becomes indirect steam and slatterns, and steam thermal system secondary recovery utilizes, and recycled is exactly this partial heat energy.
Because fed distance is longer for steam supply pipe network, it is difficult to accomplish high aobvious pick up the heat in condensate.At present, indoor steam
Condensate can be accomplished to recycle by firing equipment, and aobvious pick up the heat input-output ratio high in condensate is not allowed to find pleasure in
See.
In analysis therrmodynamic system operation, the generation of condensate and yield are all relevant with the change of system running state.1st, supply
Steam pipe net：Pipeline is in normal temperature state upon power-up of the system, enters after pipe network with steam, pipeline absorbs heat first, and steam is released
After the latent heat of vaporization, form low-temperature condensate and measure big, along with the discharge of low-temperature condensate, line temperature and steam pressure are progressively
When being increased to pressure of steam supply and temperature, the temperature of this process condensate and the water yield change greatly, and now condensate such as can not be fast
Speed drains, and can affect the pipeline heating-up time, reduces the transfer efficiency of pipeline, increases the idle damage during starting operation
Consumption.At present, steam supply pipe network does not have gully set by water separator to pass through the condensation that drain valve is difficult to produce this process
Water is discharged rapidly, is drained.Some systems are provided with manually in line valve, the direct discharge to condensate, but due to not having temperature to show
Show and water separator is difficult to control and bears water to a condensate drain and do not arrange steam.In steam supply pipe network normal course of operation, positive reason
Because pipe resistance and pipeline are put thermogenetic condensate and can be discharged it by drain valve under condition.But, because drain valve does not adjust
The function of leaving water temperature, not only causes the waste of high sensible heat in water in draining, also can cause system decompression simultaneously.
2nd, for gas utilization unit, its number of units is more, different production technologies and different daily schedules, its equipment
Pre-heat frequency is more than steam-supplying system, and the steam thermal energy that warming up period discharge condensate causes wastes the startup being far longer than steam-supplying system
Warming up period.In equipment normal course of operation produce condensed water in high temperature discharge when, not only cause the waste of steam thermal energy, simultaneously because
System decompression leads to technological temperature unstable, can affect yield and the quality of product again.
The large-scale gas utilization unit of the especially special industry such as petrochemical industry, salt industry, because technological requirement uses vapour in process of production
Amount change is very big, and installation drain valve cannot solve sensible heat in the water that the secondary vaporizing after condensed water in high temperature discharge causes and waste
Problem.Drain valve do not installed substantially by this kind of industry Large steam firing equipment, by way of hermetic reclaim or step recycling
Process the waste problem that in condensate, high sensible heat secondary vaporizing causes, but cannot fundamentally solve once utilizing of steam thermal energy
Rate.Currently, the energy waste for therrmodynamic system operation is it would be highly desirable to the energy conserving system that release can adjust condensate discharge temperature takes
With thorough, generation tradition power consumption drain valve, solves the problems, such as that discharging condensed water in high temperature causes high sensible heat in water to waste.
