Abstract
The invention discloses a secondary steam-recycling method for a condensate collector. The method utilizes a steam-water heat exchanger to carry out heat exchange between the secondary steam in the condensate collector and the soft water in a soft water tank in order to heat the soft water in a boiler, consequently, both the sensible heat and the latent heat in the secondary steam can be sufficiently utilized, and thereby the waste of energy can be effectively reduced; meanwhile, the adoption of the method also can ensure that condensate can return into a soft tank of the boiler and is recycled, so that the waste of the water resource can be reduced as well, and thereby the production cost of enterprises can be reduced.
Description
Technical field
The present invention relates to a kind of condensate-water polishing Application way, the recoverying and utilizing method of indirect steam that particularly in a kind of cigar mill, condensate water produces.
Background technology
Cigar mill is in production of cigarettes process, in order to ensure the normal operation of scrap prodn. line process equipment and heating and ventilating equipment, need with a large amount of steam, after steam releases the latent heat of vaporization as a kind of heat energy carrier in various gas utilization unit, the saturated condensate water of intimate equality of temperature with pressure can be become, because the use pressure of steam is greater than atmospheric pressure, so the heat that condensate water has can reach the 20%-30% of the full heat of steam, and pressure, temperature is higher, the heat that condensate water has is more, the ratio accounting for steam total amount of heat is also larger, this shows, the heat of the recovery condensate water of 100% and in addition effectively utilization there is very large energy-saving potential.
The condensate water that current cigar mill production line heat transmission equipment produces generally all can get back to Condensate recovery device by buried pipe, but due to each production technology by steam pressure difference, (maximum steam pressure is not less than 0.8MPa at scrap prodn. line cut-tobacco drier place, and the operating pressure of Condensate recovery device only has 0.125MPa), therefore condensate water is easy to the flash-off steam that produces in condensing water conduit, the leaked steam of part hydrophobic valve also can enter into condensing water conduit, the indirect steam formed by flash-off steam and leaked steam in a large number will be made so again to gather in Condensate recovery device, back pressure in Condensate recovery device is raised, and then cause gas equipment blocked drain, in order to ensure that gas equipment is hydrophobic unimpeded, usually airtight Condensate recovery device is changed into open system, Condensate recovery device increases evacuated tube and emits indirect steam, the a large amount of heat being so is just wasted, cause energy waste, and a large amount of water smoke can be made to permeate in air, adverse effect is brought to plant area's surrounding enviroment, particularly more obvious in the winter time, cause the waste of water resource simultaneously.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a kind of recoverying and utilizing method that the heat of condensate water indirect steam can be made to be fully used.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
An indirect steam recoverying and utilizing method in Condensate recovery device, it comprises the steps:
1) condensate water of gas utilization unit generation is reclaimed by Condensate recovery device;
2) a steam-water heat exchanging device is set, the soft water given in the softened water tank of boiler water supply is passed through this steam-water heat exchanging device, indirect steam in Condensate recovery device is passed into this steam-water heat exchanging device simultaneously, make the soft water in steam-water heat exchanging device and indirect steam carry out heat exchange;
3) make the soft water after heating flow back to softened water tank from steam-water heat exchanging Unit, the condensed condensate water of indirect steam flows back to Condensate recovery device.
Preferably, the condensate water in Condensate recovery device delivers to softened water tank to boiler water supply by water pump.
Preferably, condensate water needs before entering softened water tank to carry out deironing process.
Preferably, the indirect steam in described Condensate recovery device directly can pass in softened water tank and heat soft water.
Technique scheme has following beneficial effect: this indirect steam recoverying and utilizing method makes the indirect steam in Condensate recovery device and the soft water in softened water tank carry out heat exchange by a steam-water heat exchanging device, carrying out heating to the soft water entering boiler makes soft water temperature raise, the sensible heat in indirect steam and latent heat can be made so to be all fully utilized, thus effectively reduce the waste of the energy, be re-used in the softened water tank simultaneously adopting the method that condensate water also can be made to get back to boiler, also can reduce the waste of water resource, and then reduce the production cost of enterprise.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail.
As shown in Figure 1, indirect steam recoverying and utilizing method in this Condensate recovery device is in implementation process, first the condensate water of gas utilization unit generation is reclaimed by Condensate recovery device 1, because the use steam pressure of each production equipment is different, therefore condensate water is easy to the flash-off steam that produces in condensing water conduit, the leaked steam of part hydrophobic valve also can enter into condensing water conduit, and the indirect steam formed by flash-off steam and leaked steam in a large number will be made like this in Condensate recovery device 1 inner accumulated.
One steam-water heat exchanging device 3 is set in one side of Condensate recovery device, this steam-water heat exchanging device 3 can be used to make steam and water carry out heat exchange, indirect steam in Condensate recovery device 1 is passed into this steam-water heat exchanging device 3, make to the soft water in the softened water tank 2 of boiler water supply by this steam-water heat exchanging device simultaneously, make indirect steam and soften in steam-water heat exchanging device 3 heat exchange, complete the rising of the soft water temperature after heat exchange and send softened water tank back to boiler water supply by water pump; Complete after the indirect steam after heat exchange becomes condensed water and again flow back in Condensate recovery device 1.
Condensate water in Condensate recovery device 1 also delivers to softened water tank to boiler water supply by water pump, for ensureing the water quality entering the condensate water of softened water tank, needs to carry out deironing process to condensate water before condensate water enters softened water tank.In addition, the indirect steam in Condensate recovery device 1 directly can be passed in softened water tank 2 by pipeline and heat soft water.
This indirect steam recoverying and utilizing method makes the indirect steam in Condensate recovery device and the soft water in softened water tank 2 carry out heat exchange by steam-water heat exchanging device 3, the soft water temperature entered in boiler is raised, the sensible heat in indirect steam and latent heat so just can be made all to be fully utilized, thus the waste of effective minimizing energy is to reduce, be re-used in the softened water tank simultaneously adopting the method that condensate water also can be made to get back to boiler, also can reduce the waste of water resource, and then reduce the production cost of enterprise.
