Description
Technical field
The invention belongs to boiler blow-off technical field, more particularly to a kind of boiler blow-off heat reclaim unit.
Background technology
In order to the quality for ensureing stove water enables boiler safe operation steady in a long-term, boiler has to carry out continuous blowdown
And periodical blowdown, continuous blowdown is recycled to oxygen-eliminating device heating by after flash distillation, producing low-pressure steam, and hot water emission is to determining row's dilatation
Device, periodical blowdown is directly discharged to determine row's flash vessel, after row's flash vessel carries out secondary dilatation pressure release surely, steam row air, high temperature
Water blending cold water is emitted into wastewater disposal basin after carrying out secondary cooling, and discharge water has a large amount of impurity and medicine, is recycled to boiler replenishing water
It is relatively costly.
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.
The content of the invention
It is an object of the present invention to be directed to boiler blow-off heat present in above-mentioned prior art can not be utilized, make
Into the defect of energy waste, there is provided a kind of boiler blow-off heat reclaim unit, to solve above-mentioned technical problem, steam can be reduced
Discharge, reduces water consume, and heat can be reclaimed again.
In order to achieve the above object, the technical scheme is that：
A kind of boiler blow-off heat reclaim unit, including determine row's flash vessel, flash vessel downside to be arranged surely is provided with blowdown main, it is special
Levy and be：Described row's flash vessel inwall of determining is provided with heat exchanger, is set on the blowdown main in the flash vessel tank body of row surely
Through hole is equipped with, to be arranged surely and be provided with sleeve pipe outside the blowdown main in flash vessel tank body, this arranges flash vessel and is additionally provided with spray desuperheating surely
Structure, described heat exchanger connection external source, the top of row's flash vessel surely is provided with steam releasing mouthful, and bottom is provided with puts
The mouth of a river.
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 method for designing can eliminate thermal expansion, strengthen anti-impact force.
Described spray desuperheating structure is sparge pipe, and valve is provided with sparge pipe.
Beneficial effects of the present invention：
A kind of boiler blow-off heat reclaim unit that the present invention is provided, helix tube suspension design is set row's flash vessel inwall is determined
Helical bundle, low-temperature receiver is heated by surface heat exchanging, carries out low pressure saturation water and steam heat is reclaimed, and flash vessel tank is arranged surely described
Through hole is provided with internal blowdown main, sleeve pipe is provided with outside the blowdown main in tank body, i.e., using decompression muffler form
The honeycomb decompression denoising structure of bilayer decompression, makes blow-off pipe using honeycomb fashion pressure release mode, and above-mentioned low-temperature receiver is designed using bypass,
It is convenient for maintenance.This design can reclaim the heat for determining saturation water and steam in row's flash vessel, reduce system entirety energy consumption, subtract
It is few that the comprehensive utilization of water is improved to empty steam releasing, flash vessel and Sewer System temperature are reduced, reduce dilatation cooling water and come into operation.
Additionally, design principle reliability of the present invention, simple structure, with application prospect widely.
As can be seen here, the present invention compared with prior art, improves with prominent substantive distinguishing features and significantly, and it is implemented
Beneficial effect be also obvious.
Brief description of the drawings
Fig. 1 is a kind of structural representation of boiler blow-off heat reclaim unit that the present invention is provided.
Wherein, 1- arranges flash vessel surely, and 2- blowdown mains, 3- heat exchangers, 4- sleeve pipes, 5- spray desuperheating structures, 6- outsides are cold
Source, 7- steam releasings mouthful, 8- dewatering outlets.
Specific embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of boiler blow-off heat reclaim unit that the present invention is provided, including determining row's flash vessel 1, fixed row expands
Container downside is provided with blowdown main 2, and described row's flash vessel inwall of determining is provided with heat exchanger 3, and flash vessel tank is arranged surely described
Through hole is provided with internal blowdown main, sleeve pipe 4 is provided with outside the blowdown main in the tank body, this arranges flash vessel also surely
Spray desuperheating structure 5 is provided with, described heat exchanger connection external source 6, the top of row's flash vessel surely is provided with steam and puts
The bottom of raw edge 7 is provided with dewatering outlet 8.
In the present embodiment, described heat exchanger is the helical bundle using helix tube suspension design, this method for designing 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 increases attachment helical bundle, absorbs saturated vapor heat in container
Amount, flash vessel internal capacity is not reduced.
Stable by actual motion more than half a year, it was demonstrated that the project implementation works well, having reached design will
Ask.
1st, heat recovery：
Condense water temperature enthalpy difference * waters/standard coal heat * unit price=about 100,000 yuan/year.
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, deoxygenation moisturizing temperature is raised.
Disclosed above is only the preferred embodiment of the present invention, but the present invention is not limited to this, any this area
What technical staff can think does not have creative change, and some improvement made without departing from the principles of the present invention and
Retouching, should all be within the scope of the present invention.
