Description
Technical field
The utility model belongs to boiler blow-off technical field, more particularly to a kind of boiler blow-off heat reclaim unit.
Background technology
In order to ensure that the quality of stove water enables boiler safe operation steady in a long-term, boiler has to carry out continuous blowdown
And periodical blowdown, after continuous blowdown is by flash distillation, produces low-pressure steam and be recycled to oxygen-eliminating device heating, hot water emission is to determining row's dilatation
Device, periodical blowdown is directly discharged to determine row's flash vessel, and flash vessel is arranged surely and is carried out after secondary dilatation pressure release, steam row air, high temperature
Water blending cold water carries out being emitted into wastewater disposal basin after secondary cooling, and discharge water has a large amount of impurity and medicine, is recycled to boiler replenishing water
Cost is higher.
This is prior art weak point.
Therefore, for defect of the prior art there is provided a kind of boiler blow-off heat reclaim unit, to solve above-mentioned technology
Problem is necessary.
Utility model content
The purpose of this utility model is, profit can not be obtained for boiler blow-off heat present in above-mentioned prior art
With causing the defect of energy waste there is provided a kind of boiler blow-off heat reclaim unit, to solve above-mentioned technical problem, can drop
Low discharge of steam, reduces water consume, heat can be reclaimed again.
In order to achieve the above object, the technical solution of the utility model is：
A kind of boiler blow-off heat reclaim unit, including determine row's flash vessel, arrange surely and be provided with blowdown main on the downside of flash vessel,
It is characterized in that：Described row's flash vessel inwall of determining is provided with heat exchanger, the blowdown main in the flash vessel tank body of row surely
On be provided with through hole, surely arrange flash vessel tank body in blowdown main outside be provided with sleeve pipe, this arranges flash vessel and is additionally provided with water spray surely
Desuperheat structure, described heat exchanger connection external source, the top of row's flash vessel surely is provided with steam releasing mouthful, and bottom is set
There is dewatering outlet.
Preferably, described heat exchanger is the helical bundle using helix tube suspension design, and the helical bundle is attached to
Surely flash vessel inwall is arranged, this design method can eliminate thermal expansion, strengthen anti-impact force.
Described spray desuperheating structure is to be provided with valve on sparge pipe, sparge pipe.
The beneficial effects of the utility model：
A kind of boiler blow-off heat reclaim unit that the utility model is provided, sets helix tube to hang determining row's flash vessel inwall
The helical bundle of meter is hung, low-temperature receiver is heated by surface heat exchanging, low pressure saturation water is carried out and steam heat is reclaimed, row is determined described
Sleeve pipe is provided with outside the blowdown main being provided with blowdown main in flash vessel tank body in through hole, tank body, i.e., is disappeared using decompression
The honeycomb decompression denoising structure of sound device form bilayer decompression, makes blow-off pipe use honeycomb fashion pressure release mode, and above-mentioned low-temperature receiver is used
Bypass design, is convenient for maintenance.This design can reclaim the heat for determining saturation water and steam in row's flash vessel, and reduction system is whole
Physical efficiency consumes, and reduces the comprehensive utilization that water is improved to empty steam releasing, reduction flash vessel and Sewer System temperature, reduces dilatation cold
But water comes into operation.
In addition, the utility model design principle is reliable, and it is simple in construction, with application prospect widely.
As can be seen here, the utility model compared with prior art, with substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings
Fig. 1 is a kind of structural representation for boiler blow-off heat reclaim unit that the utility model is provided.
Wherein, 1- arranges cold outside flash vessel, 2- blowdown mains, 3- heat exchangers, 4- sleeve pipes, 5- spray desuperheating structures, 6- surely
Source, 7- steam releasings mouthful, 8- dewatering outlets.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is elaborated by specific embodiment.
As shown in figure 1, a kind of boiler blow-off heat reclaim unit that the utility model is provided, including determine row's flash vessel 1, it is fixed
Blowdown main 2 is provided with the downside of row's flash vessel, described row's flash vessel inwall of determining is provided with heat exchanger 3, dilatation is arranged surely described
Through hole is provided with blowdown main in device tank body, sleeve pipe 4 is provided with outside the blowdown main in the tank body, this arranges dilatation surely
Device is additionally provided with spray desuperheating structure 5, and described heat exchanger connection external source 6, the top of row's flash vessel surely is provided with steaming
The bottom of vapour diffusion mouth 7 is provided with dewatering outlet 8.
In the present embodiment, described heat exchanger is the helical bundle using helix tube suspension design, this design method energy
Thermal expansion is eliminated, strengthens anti-impact force.
By the way that to determining the transformation that row's flash vessel is carried out, inwall increase attachment helical bundle absorbs saturated vapor heat in container
Amount, flash vessel internal capacity is not reduced.
It is stable by actual motion more than half a year, it was demonstrated that the project implementation works well, reach that design will
Ask.
1st, heat recovery：
Condense yuan/year of water temperature enthalpy difference * waters/standard coal heat * unit prices=about 100,000.
2nd, kinetic energy cost：
Hydraulic pressure potential energy is converted, and is ignored.
Cooling water injected volume can be effectively reduced after coming into operation, this kinetic energy cost is reduced, saturated vapor discharge capacity is greatly reduced,
Under square one, sewage discharge temperature drop, the rise of deoxygenation moisturizing temperature.
Disclosed above is only preferred embodiment of the present utility model, but the utility model is not limited to this, any
What those skilled in the art can think does not have creative change, and is made under the premise of the utility model principle is not departed from
Some improvements and modifications, should all fall in protection domain of the present utility model.
