Background technology
Heat transmission equipment with steam as thermal source can produce condensed water in heat transfer process.Different heat transmission equipments is affected by equipment inner structure, and produced condensate temperature also has difference.As a example by alumina leaching workshop section, during tube digestion uses high temperature, high pressure initial steam indirectly to heat dissolved mineral slurry, the sleeve pipe of initial steam heating is often affected by casing length, and the condensate temperature of discharge can be slightly different.At initial steam heating muff top, owing to slurry temperature is relatively low, condensate temperature out is relatively low, and corresponding pressure is relatively low;At initial steam heating muff end, ore pulp is higher through above initial steam temperature after heating, and now initial steam and ore pulp heat exchange condensate temperature out and pressure are corresponding the highest.Being discharged in a condensate water pot if be aggregated on a house steward by the condensed water of all of initial steam heating muff, arising that the phenomenon of pressure imbalance, what pressure reduction was high directly results in the vibration of pipeline.Simultaneously, the condensed water at initial steam heating muff top is relatively low due to temperature, the condensed water pressure that corresponding pressure ratio initial steam heating muff terminal temperature is higher is low, the condensed water causing low-pressure end amasss in pipeline, smooth and easy cannot drain into condensate water pot, make corresponding casing pressure increase, produce potential safety hazard.Can affect time serious and set up stable dissolution thermal balance, cause the steam consumption of dissolution to increase.
Summary of the invention
It is an object of the invention to: the device of condensed water in a kind of discharge heat transmission equipment with steam as thermal source is provided, so that solution is existing, condensed water all of in heat transmission equipment is entered in condensate water pot by house steward, temperature and the difference of pressure due to each several part condensed water, easily cause the vibrations of pipeline, simultaneously, in heat transmission equipment, temperature and the relatively low condensed water of pressure easily amass in pipeline, smooth and easy cannot drain into condensate water pot, pressure at corresponding heat transmission equipment is made to increase, produce potential safety hazard, can affect time serious and set up stable dissolution thermal balance, cause the problem that the steam consumption of dissolution increases.
The present invention program is as follows: the device of condensed water in a kind of heat transmission equipment discharged with steam as thermal source, described device includes condensate water pot, steam condensate (SC) flash-pot, the first discharging tube and the second discharging tube, described heat transmission equipment is with steam as thermal source, the bottom of heat transmission equipment is provided with leakage fluid dram, each leakage fluid dram respectively by the first discharging tube correspondingly entrance with a condensate water pot be connected, the outlet of each condensate water pot is connected with steam condensate (SC) flash-pot by the second discharging tube respectively.
Ultimate range between minimum number and adjacent two leakage fluid drams of leakage fluid dram determines according to the pressure reduction between temperature and the cold icepro night adding vapours and the temperature difference.
When the temperature adding vapours is less than 200 DEG C, between adjacent two leakage fluid drams, the maximum temperature difference of condensed fluid should be less than 20 DEG C, when in heat transmission equipment, temperature is more than or equal to 200 DEG C, between adjacent two leakage fluid drams, the maximum differential pressure of condensed fluid should be less than 0.5MPa, thus determines the ultimate range between adjacent two leakage fluid drams according to the temperature difference and pressure reduction between each several part condensed water in heat transmission equipment.
When the temperature adding vapours is less than 200 DEG C, at least provided with a leakage fluid dram between the region that the temperature difference is 20 DEG C between condensed water in heat transmission equipment, when in heat transmission equipment, temperature is more than or equal to 200 DEG C, at least provided with a leakage fluid dram between the region that pressure reduction is 0.5MPa between condensed water in heat transmission equipment.
Described heat transmission equipment is an integral device or multistage equipment is sequentially communicated and forms.
Compared with prior art, major advantage is as follows for the present invention:
1, on heat transmission equipment, each leakage fluid dram has been respectively communicated with a condensate water pot, make different temperatures in heat transmission equipment, the condensed water of different pressures can flow into different condensate water pots from different leakage fluid drams respectively, and finally respectively enter in steam condensate (SC) flash-pot, the condensed water avoiding each several part temperature and pressure different mixes, the problem being easily caused the vibration of pipeline, simultaneously, the different condensed water of each several part pressure and temperature is flowed out by the leakage fluid dram near each, the condensed water eliminating low-pressure end amasss the potential safety hazard produced in pipeline, improve the thermal efficiency of dissolution initial steam, reduce the steam consumption of heat transfer process;
2, the ultimate range between position and adjacent two leakage fluid drams of leakage fluid dram has been made to limit by the present invention according to the maximum differential pressure added between the temperature of vapours and described adjacent two leakage fluid drams and maximum temperature difference, thereby further ensures that in heat transmission equipment, the condensed water of different pressures and temperature all can be discharged smoothly.
