Hot systems 20 and the heat exchanger of technique side 12.It is of course also possible to which each group (set, unit) is arranged to two heat exchangers and one
The mode of heat-exchange system is passed between a.
Specifically, in the prior art, circulation is once polluted by processing medium in heat transfer process, and recirculated water is big
Amount is replaced and is discharged, and a large amount of pollutant effluents is generated, and for the deficient area in water source, water resource waste, while increasing environmental protection
The operating pressure of device.
Recirculated water with in corrosive processing medium diabatic process, easily causing exchanger tube wall to be corroded perforation and
It enters in circulation, causes circulation water pollution, ammonia nitrogen pollutant that circulating water PH value can be caused to increase generation
Caustic embrittlement endangers, and sulphide staining object can cause pH value to decline generation corrosion harmfulness, and oil pollutant sticks heat-transfer surface, influences to exchange heat
Efficiency, fuel gas pollutant can make circulation generate inflammable, explosive risk, and organic pollution can make total number of bacteria sudden and violent
Rise, therefore glutinous mud amount drastically increases, heat exchange efficiency is caused to reduce, and restricts the produce load of process system, while aggravating
The risk of underdeposit corrosion.Currently, technically there are no the effective technologies that circulation is leak into for processing medium, it is still place
It is leaked in first, the present situation for the emergency disposal administered afterwards, general procedure is using being initially switched off source of leaks, then with times over possessing water
The production water of amount carries out displacing contaminated recirculated water, and the contaminant water water quality for being replaced out does not meet environmental requirement, must
After must being handled or reuse or discharge, contaminant water run well all to sewage-treatment plant in water, water quality be impact and
It destroys.The no pollution of circulation difficult to realize, seriously restricts the zero-emission of sewage.
Currently, the heat-exchange system that circulation uses all is tube wall type heat exchanger, all it is to be passed by sharing a tube wall
The structure of heat, tube wall are once corroded by processing medium, and processing medium just enters circulation at pollutant.Although immersing
Formula heat exchanger is to design a kind of tube wall type heat exchanger for leaking medium, because its volume that exchanges heat is larger, the corruption to processing medium
Erosion leakage has certain spatial cache, but still is not enough to alleviate to the system-wide pollution of recirculated water, and convection transfer rate
It is relatively low, in addition in container fluid it is bulky.In addition, heat transfer temperature difference is relatively low and less quick to the change of operating mode
Sense, so immersion heat exchanger is still the pollution problem that can't resolve recirculated water processing medium.
In order to solve the technical barrier that recirculated water is polluted by heat transferring medium, accomplishes circulation no pollution, accomplish
Prevent preposition, prevention to combine, both makes polluted or have enough buffer time to confirm and dispose.Also it passes and changes between solving very well
The relatively low technical problem of hot systems heat transfer temperature difference is in time followed the heat transfer of processing medium by a biography heat-exchange system
Ring water system constantly balances the both sides heat exchanger heat transfer temperature difference, both sides heat exchanger is made to remain dynamic heat balance.
It is provided with the three parts such as monitoring surge tank, variable frequency pump, on-line monitoring system in biography heat-exchange system.Wherein, exist
Line monitoring system includes detector.Detector is arranged in monitoring surge tank, and detector includes teletransmission conductivity gauge (ORC instrument), PH
Instrument, ammonia nitrogen instrument, COD instrument, oils instrument, gas analyzer (hydrogen, liquefied gas, methane) carry out automatic detection in real time.Once detection
It is exceeded to one of which pollutant：Ammoniacal nitrogen >=15mg/l, COD >=80mg/l, BOD5>=5mg/l, oils >=0.5mg/l, sulphur
One kind in compound >=0.1mg/l, PH >=9 or PH≤6, TDS >=1000mg/l, detector can automatic alarm remind artificial carry out
It investigates to confirm pollutant, then takes appropriate measures.If detecting it is hydrogen, liquefied gas etc. is inflammable, explosion hazard gases is let out
Leakage, Cutting process side heat exchanger, prevents from forming explosive gas, and to monitoring surge tank into line replacement technological processing for explosion protection feature immediately.Such as
Fruit leakage is the medium that the non-aggressives such as COD do not influence heat transfer effect, can maintain to run, and monitoring surge tank can not have to displacement
Processing.Once being ammonia nitrogen, the strong processing medium pollution of the corrosivity such as hydrogen sulfide should then switch technique side heat exchanger, carry out again
Displacement prevents from continuing to corrode to cold side heat exchanger, pollutes in circulation.Because monitoring surge tank has monitoring and sets
The function of changing ensure that circulation water quality exists so pollutant is just isolated and buffers after passing heat-exchange system between entering
It is not contaminated in certain time.In both sides, the shell side of heat exchanger is provided with that thermometer is chain with variable frequency pump, the temperature difference of the two
It is exactly the cooling extent of recirculated water, frequency should be increased if the temperature difference is small, accelerate Hydraulic Circulation, improve flow velocity, reinforces heat transfer speed
Rate ensures the temperature difference of both sides between 10~12 DEG C.In time by the heat transfer of processing medium to recirculated water.It passes and changes between avoiding
Hot systems temperature is detained, and the case where rate of heat transfer reduction occurs.
Cold side heat exchanger, that is, First Heat Exchanger, i.e. the second heat exchanger of technique side heat exchanger are using conventional tube wall type heat exchange
Device is all separate heat transfer process, and by monitoring surge tank, variable frequency pump is realized to be recycled both sides heat exchanger with both sides heat exchanger
Heat transfer, the process of heat exchange.Cooling water is transferred heat to by cold side heat exchanger is recycled to after the heat absorption of technique side.Again by becoming
Frequency pump provides between power improves and passes velocity of medium, constantly keeps both sides heat exchanger heat balance.
The volume of monitoring surge tank passes 2~3 times of heat-exchange system piping volume between being.It plays buffering and concentrates the work of displacement
With, while having the function of gas-water separation.Wherein monitoring surge tank is equipped with water supply line, and flowing line, exhaust apparatus, system follows
Ring medium can be production water, demineralized water, and a biography medium can not have to plus antisludging agent, any medicament such as fungicide.
Can be according to technique side heat transferring medium different attribute, such as pressure, gas, liquid, toxic, burn into is inflammable, explosive spy
Property can the setting of circulating water device it is one or more it is such between pass heat-exchange system.
Processing medium has corrosivity, only pollutes the heat transfer medium monitored in surge tank leaking, no
It can directly pollute in circulation, play a sufficiently long buffer time, herein regular quality inspection, it is each that placement is installed
The instrument of class medium pollution, such as oil-stain-preventing are infected with oils, ammonia nitrogen, COD, TDS, the instrument such as pH value, and surge tank has gas-liquid separation
Effect, it is possibility to have effect ground prevents the processing of combustible gas leakage, and can discharge in time.
Biography heat-exchanger rig efficiently avoids processing medium between this recirculated water and industrial circulating water system passes through tube wall type
Heat exchanger contacts, once the time without buffering is revealed, because circulation water is very big.Heat-exchange system is passed between having just
There can be buffer time, optional leeway is larger, and pollutant can be recycled temporarily in biography heat-exchange system, certain
It will not cause the danger of corrosion in time to cold side heat exchanger at once, it is ensured that recirculated water will not be contaminated immediately, may be implemented
The no pollution of processing medium saves the discharge capacity for carrying out largely replacing water because of heat transferring medium Pollution Cycle water, while also subtracting
Operating pressure of the light contaminant water to sewage-treatment plant.
Specifically, 38 DEG C of return water temperature enters cooling tower water distribution by circulating backwater pipeline after the water cooling equipment heat exchange of certain factory
Guan Zhong is sent to the cooling water heat exchanger of process units by water circulating pump by manifold line pressures again after cooling 26 DEG C of tower cooler
In, then by tube wall type heat exchanger absorb between pass the heat of heat-exchange system and cool down again from flowing back into cooling tower by overbottom pressure,
Reciprocation cycle, circulation set other filter system, the auxiliary equipment such as medicine system.Between pass heat-exchange system carry intermediate heat
Function realizes that processing medium is acted on the thermally equilibrated transmission of cooling water, and a biography heat transferring medium, which is cooled after water cools down, reaches 26
DEG C by buffering detect tank temporary buffer storage, monitor surge tank in setting teletransmission conductivity gauge (ORC instrument), PH instrument, ammonia nitrogen instrument,
COD instrument, oils instrument, gas analyzer (hydrogen, liquefied gas, methane) carry out automatic detection in real time, find one of which pollutant
Exceeded (ammoniacal nitrogen >=15mg/l；COD≥80mg/l；BOD5≥5mg/l；Oils >=0.5mg/l；Sulfide >=0.1mg/l；PH
>=9 or PH≤6；TDS >=1000mg/l), detector automatic alarm artificially carries out the pollutant that investigation confirms leakage, then adopts
Take corresponding measure.If detecting it is hydrogen, the flammable explosive gas such as liquefied gas leak, immediately Cutting process side heat exchanger,
It prevents from forming explosive gas.If leakage is the medium that the non-aggressives such as COD do not influence heat transfer effect, can maintain to run,
Monitoring surge tank can not have to replacement Treatment.Once being ammonia nitrogen, the strong processing medium pollution of the corrosivity such as hydrogen sulfide should then be cut
Technique side heat exchanger is changed, prevents from corroding cold side heat exchanger into line replacement again, pollute in circulation.Because
Monitoring surge tank has the function of monitoring and replace, so pollutant is just isolated and buffers after passing heat-exchange system between entering,
It ensure that circulation water quality is not contaminated.Medium is passed between monitoring surge tank, and 26 DEG C of cooling waters are got to by technique by variable frequency pump
In the heat exchanger of side carry out heat exchange absorption technique medium heat, after being warming up to 38 DEG C by overbottom pressure return to cold side heat exchanger into
Row heat exchange.Variable frequency pump is chain for temperature difference in chain two heat exchanger shell pass, when temperature difference is less than 10~12 DEG C, just plus
Fast frequency conversion increases rate of circulating flow, accelerates to be conducive to heat transfer.So cycle realizes the heat dynamic equilibrium of both sides heat exchanger constantly.
