Description
Technical field
The present invention relates to a kind of boiling pan of recycling residual heat, belong to Sugar Engineering technical field.
Background technology
Sugarcane (or beet) obtains after three squeeze juice extracting, peace and quiet removal of impurities and evaporation and concentration processes in sugar industry
Syrup, syrup can obtain white granulated sugar after cane sugar boiling and crystal.Boil the key link that sugar is sugaring process, quality to product and
Full factory energy consumption has important influence, and its main task is to be concentrated to syrup or molasses in boiling pan (or crystallizing tank)
Certain degree of supersaturation, crystal seed (magma or Icing Sugar) is then put into, and crystal is gradually brought up, will from obtaining meeting product quality
The sucrose crystal asked.
It is mainly that the effect juice vapour and two from evaporation section imitates juice vapour to boil the heating steam used in sugar, and its temperature is 110
DEG C~120 DEG C, often contain more on-condensible gas in these juice vapour, these on-condensible gases will not be as water vapour by itself
Heat can become vapor condensed water outlet discharge of the vapor condensed water from boiling pan after being transmitted to material, and they can be accumulated in steam drum, occupy vapour
Bulging space, one layer of air film is formed around heating tube, so as to have impact on the exchange of heat so that heat transfer coefficient drops significantly
It is low, so as to reduce the operating efficiency of boiling pan.Therefore, vapour that must in time on-condensible gas from boiling pan in sugar boiling process
Excluded in drum, prevent it from producing harmful effect to sugar boiling process.
The heating steam (effect, two effect juice vapour) boiled used in sugar is bigger than atmospheric pressure, therefore at present in boiling pan heating chamber
The wipe-out mode of on-condensible gas is mainly：Not condensing body drain is installed in the place that on-condensible gas is concentrated, on-condensible gas is straight
Run in and be put into air.Although this method can exclude the on-condensible gas in boiling pan heating chamber, enable to boil sugared concentration process
Larger heat transfer coefficient is obtained, but the temperature and pressure of on-condensible gas is all higher, it is still containing more heat, its is direct
It is discharged into air, is the significant wastage to the energy.Therefore it provides a kind of boiling pan of recycling residual heat boils sugared add to reclaim
The heat energy of on-condensible gas is necessary in vapours.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, there is provided a kind of boiling pan of recycling residual heat, with recovery
The heat energy of on-condensible gas in sugar heating steam is boiled, solution is boiled on-condensible gas in sugar heating steam and is directly discharged in air, causes
The problem of energy waste.
To achieve these goals, present invention employs following technical scheme：
A kind of boiling pan of recycling residual heat, including tank bottom, steam chest and steam drum, tank bottom is provided with feed pipe and massecuite goes out
Mouthful, steam chest is provided with juice catching device and juice vapour outlet, and steam drum is provided with vapor condensed water drain, heating steam inlet tube and on-condensible gas
Drain, the outlet of on-condensible gas drain are connected on feed pipe.
Described on-condensible gas drain is provided with two on-condensible gas imports, is on-condensible gas lower inlet respectively and does not coagulate
Gas upper inlet.
Described on-condensible gas lower inlet and the distance of lower perforated plate are 100~200mm.
Described on-condensible gas upper inlet is located above upper perforated plate at 5~10mm.
Described on-condensible gas drain is provided with valve.
Compared with prior art, the beneficial effect that the present invention possesses：
(1) the on-condensible gas drain outlet of boiling pan is connected on feed pipe by the present invention, is had using on-condensible gas
Some heat syrup or molasses, the heat energy of on-condensible gas is reclaimed, traditional sugar boiling process is avoided and directly arranges on-condensible gas
Fall, the problem of causing energy waste.
(2) present invention is respectively provided with on-condensible gas lower inlet and upper inlet according to the difference of on-condensible gas density, has
Beneficial to the abundant exclusion of on-condensible gas.On-condensible gas is made up of multiple gases, and the density ratio water vapour of some gases is big, and some are then
Smaller than the density of water vapour, they can accumulate in the different parts of steam drum；The present invention is set in the upper and lower part of steam drum (shell side)
There is exhaust outlet, so as to be advantageous to the abundant exclusion of on-condensible gas；The distance of on-condensible gas lower inlet and lower perforated plate be 100~
200mm, distance is too small to cause on-condensible gas lower inlet to suck vapor condensed water, and distance is unfavorable for greatly very much accumulating in steam drum bottom not
The exclusion of solidifying gas；For the exclusion beneficial to the on-condensible gas for accumulating in steam drum top, on-condensible gas upper inlet is higher than upper perforated plate by 5
~10mm.
(3) outlet of on-condensible gas drain is connected by the present invention with feed pipe, and position is more reasonable.Due to boiling used in sugar
Heating steam (an effect juice vapour, two effect juice vapour) pressure is larger, and after the valve on on-condensible gas drain is opened, on-condensible gas is just
It can be injected directly into feed pipe, heat syrup or molasses in feed pipe；If the outlet on-condensible gas drain is direct
Insert in boiling pan (steam chest), because to boiling the sugared later stage, the viscosity of massecuite is big with respect to the raw material (syrup or molasses) for boiling sugar to be obtained
It is more, along with the exclusion of on-condensible gas is intermittently operated, when on-condensible gas drain does not have on-condensible gas discharge, easily
On-condensible gas is caused to exclude blockage.
(4) present device is simple in construction, convenient and practical, rational technology, cost are relatively low, is advantageous to promote and uses.

Pipe 10 is sprayed onto in feed pipe 14, then is entered by feed pipe 14 in steam chest 7, finally with sugar boiling process caused by indirect steam,
Pass sequentially through juice catching device 8, juice vapour outlet 9 is taken away by condenser or vavuum pump.On-condensible gas enter feed pipe 14 after, with syrup or
Molasses are contacted, and its own waste heat is passed into syrup or molasses.In the process, heat possessed by on-condensible gas is utilized
Syrup or molasses, the heat energy of on-condensible gas is reclaimed, avoid traditional sugar boiling process and on-condensible gas is directly drained, cause the energy unrestrained
The problem of taking.Valve 11 is used for switch and the size for controlling on-condensible gas to discharge.
Described on-condensible gas drain 10 is provided with two on-condensible gas imports, is the He of on-condensible gas lower inlet 3 respectively
On-condensible gas upper inlet 6.
The distance of described on-condensible gas lower inlet 3 and lower perforated plate 17 is 100~200mm.Distance is too small to be caused not coagulate
Gas lower inlet 3 sucks vapor condensed water, and distance is unfavorable for greatly very much accumulating in the exclusion of the on-condensible gas of the bottom of steam drum 15.
Described on-condensible gas upper inlet 6 is located at 5~10mm of the top of upper perforated plate 5, and this is advantageous to accumulate on steam drum 15
The exclusion of the on-condensible gas in portion.
Operation principle and process：
