Description
Technical field
The present invention relates to heat supply process, more particularly to hot water circuit converter.
Background technology
In China's industrial and agricultural production, a large amount of 50-100 DEG C of spent hot water is discharged, since spent hot water contains impurity,
Thermal energy is difficult to recycle, all waste emission.Wherein, the washing slag water of iron and steel enterprise is exactly an exemplary.
China has been the big country of steel production, and the annual output of steel accounts for the 40% of Gross World Product.Either steel-making is gone back
It is ironmaking, a large amount of clinker will be generated.Clinker is accompanied generation with steel, it is the byproduct of smelting iron and steel, and is one
The primary condition of the important metallurgical reaction of series, it directly participates in the physical-chemical reaction and mass-and heat-transfer mistake of steel smelting procedure
Journey, it not only influences iron and steel output, quality, but also has close relationship with the consumption of raw material, energy.
In Ferrous Metallurgy stove, 1400-1500 DEG C of high temperature furnace slag is generated, enters flushing cinder after cinder notch flows out, then through slag runner
When chute, with certain water, hydraulic pressure and the chute gradient, make water with slag stream at certain angle of cut, slag is burst by cold shock
At the qualified grain slag of certain particle size.After pulp water separation, clinker is used as construction material；The flushing cinder of heat exchange is carried out with high temperature furnace slag
Water, into flushing cinder pond.
Flushing cinder pond usually takes up an area thousands of square metres, and hot vapour is emptied above flushing cinder pond, and flushing cinder coolant-temperature gage is maintained at throughout the year
60-80 DEG C, be a huge potential thermal energy energy, if can effectively be used, such as utilizes the heat of washing slag water
Can, winter heats for residential block, can be not only that country saves a large amount of fuel, but also reduces carbon emission, protect environment.
The heat energy recycle problem of washing slag water, there are no be well solved so far.
Due to washing slag water Reusability, the plurality of inorganic salt contained in clinker and oxide have been dissolved into washing slag water, have been formed
The almost saline and alkaline aqueous solution of saturation.During clinker is burst into grain slag by cold shock, some tiny clinker
Into suspending in water.Through actually detected, flushing cinder water turbidity is 60-80mg/l.
Certain heating enterprise, by dividing wall type heat exchanger, by the heat transfer of washing slag water to recirculated water, using recirculated water to residence
It heats in people area.Only one winter, the heating duration less than 4 months, the washing slag water side of dividing wall type heat exchanger, fouling reach 3-5 lis
Rice, dirty layer is hard, becomes loose after weathering.
To think after analysis, the composition of washing slag water fouling in heat exchanger is a variety of inorganic salts containing the crystallization water, such as containing
The silicate of the crystallization water.The hard crystallization incrustation scale of washing slag water, makes dividing wall type heat exchanger almost scrap.
Filter filtering washing slag water is attempted to, to solve the problems, such as washing slag water scaling on heat exchangers.Washing slag water is
The saline-alkali water of Multiple components, for saline-alkali water, filter is completely useless.Saline-alkali water can pass through any filter, and
It has arrived inside heat exchanger, has encountered cold heat exchanger wall surface, saline-alkali water cooling, supersaturation crystallizes on cold wall face at once.
In saline and alkaline aqueous solution, the process of Crystallization is known as crystallizing.There are two types of the method for crystallization is general：It is molten one is evaporating
Agent method, it, which is suitable for temperature, influences solubility little substance.Coastal area produces this method exactly utilized of evaporating brine.Separately
One is the hot saturated solution method of cooling, this method is increased suitable for temperature, solubility also increased substance.Such as the salt of northern area
Lake, summer temperature is high, occurs without crystal on lake surface；Every winter, temperature reduce, crystal soda (Na2CO310H2O), saltcake
(Na2SO410H2O) etc. substances just separate out in salt lake.Washing slag water fouling is cooled down just because of on heat exchanger wall surface
Saline and alkaline hydro-thermal saturated solution, the crystallization of generation.
In industrial or agricultural and people's lives, various sewage are discharged, a portion is that temperature is 50-100 DEG C useless
Hot water, such as washing slag water.Since the impurity component contained in spent hot water is complicated, if recycling heat using common dividing wall type heat exchanger
Can, heat exchanger may be contaminated and cisco unity malfunction soon.
For the recycling problem of spent hot water's thermal energy, a kind of waste-heat recovery device-directly-heated machine using phase-change heat-exchange meet the tendency of and
It is raw, solve the pollution problem of the various impurity heat exchanging devices in spent hot water well.
But spent hot water's phase-change heat-exchanger including directly-heated machine is different from common dividing wall type heat exchanger, it is direct
Contact heat exchanger.It by the steam-heated heating circulation water of spent hot water, is mixed with steam in heat exchanger, heating circulation water is not
It in Bottomhole pressure, but is sprayed in heat exchanger, the water droplet of sprinkling is interrupted flow.Such case just brings a problem：
Heating cycle aquaporin in interrupted heat exchanger, it is impossible to be a part for closed regional hot water heating network, that is, the two
It cannot directly be connected to.
So, how the waste-heat recovery devices such as directly-heated machine are generated into heating circulation hydro-thermal amount and passes into hot water heating pipe
Net, in order to solve this problem, simplest method are exactly to utilize a dividing wall type heat exchanger, and side is hot water floor heating heat
Water flow passage, the other side are the heating circulation water flow passages of directly-heated machine output.
But solve to conduct heat between directly-heated machine and hot water floor heating using dividing wall type heat exchanger, bring two problems：
1, this dividing wall type heat exchanger heat exchange amount is huge, of high cost；
2, the heat transfer temperature difference of dividing wall type heat exchanger makes the heat of output reduce heat supply temperature.
