To drying materials unit, referred to as air dryer.The efficiency of air heater influenced by steam quality it is very big, steam it is aqueous and
Efficiency is greatly reduced when air.Ponding inside air heater, can cause outlet air temperature to be layered, influence technique, can also make
At the corrosion leakage of heating unit, winter will also result in the bursting by freezing damage of heating unit.In addition, air heater waste steam
Problem is generally existing.Air heater energy efficiency equipment of the invention specially solves problem above, realizes air heater
Energy efficiency and service life extend.
Summary of the invention
In order to solve existing issue, the purpose of the present invention is to provide air heater energy efficiency equipment.
The present invention is achieved through the following technical solutions: a kind of air heater energy efficiency equipment, comprising: temperature
Spend control system 1, draining system 2 and flash system 3.1 entrance of temperature control system is connect with steam pipe road is come, and outlet adds with air
The rear end bringing-up section of hot device communicates；Draining system 2 divides high pressure and low pressure two parts, after high-pressure section entrance and air heater
End bringing-up section outlet connects, and high-pressure section outlet is connected with 3 entrance of flash system, 2 low-pressure section entrance of draining system and air
Bringing-up section outlet in heater front end connects, and low-pressure section outlet and 3 outlet at bottom of flash system connect together；Flash system 3
Top exit is connected to air heater front end bringing-up section.
As a further improvement of the present invention, 4 entrance of pressure-reduced and-regulated system is connected with the entrance of temperature control system 1, out
Mouth is connected to 3 top exit of flash system and air heater front end bringing-up section.
As a further improvement of the present invention, the entrance and steam line of steam-water separation equipment 5 connect, Horizontal Exit with
Temperature control system 1, pressure-reduced and-regulated system 4 communicate, and the lower end outlet of steam-water separation equipment 5 is communicated with the entrance of flash system 3.
As a further improvement of the present invention, in the top of steam-water separation equipment 5 installation emptying device of air 6.
The invention has the advantages that 1, to the local use again of the heat in the condensed water generated after steam heat release, reach section
It can effect；2, after the thermal energy in condensed water is utilized, the secondary steam amount that the condensed water discharged generates is reduced, and is eliminated common
A large amount of white vapour outside emit phenomenon, met environmental requirement；3, the thermal energy in condensed water is utilized in the form of secondary steam, is eliminated
Condensed water, which is returned directly to front end bringing-up section, leads to equipment corrosion aggravation and winter bursting by freezing problem；4, effectively in discharge air heater
Condensed water eliminates the lamination of air heating temperature, improves technique；5, the air in removal system and other incoagulability gas
Body improves the heating efficiency of air heater；6, the present invention helps to reduce air heater maintenance rate and extends its service life.

Specific embodiment
With reference to the accompanying drawing 1, detailed description of the preferred embodiments: in order to make mesh of the invention
, technical solution and advantage be more clearly understood, be further described below in conjunction with attached drawing 1 and case study on implementation.It should be appreciated that
Concrete case described herein is only used to explain the present invention, is not intended to limit the present invention.
A kind of air heater energy efficiency equipment of the invention, structure are as shown in Figure 1.Temperature control system 1 is controlled
Air heater outlet air themperature processed, steam enter the rear end bringing-up section of air heater, rear end by temperature control system 1
The condensed water of bringing-up section outlet enters the high pressure draining part of draining system 2, subsequently into flash system 3.Flash system 3 is wrapped
Include flashing apparatus, hydrophobic station and other attachmentes.Condensed water generates secondary steam in flash system 3, and secondary steam is from flash distillation
The top of system 3 enters the front end bringing-up section of air heater, and the condensed water of air heater front end bringing-up section passes through draining system 2
Low pressure hydrophobic part after with 3 bottom of flash system it is hydrophobic station discharge condensed water together with recycle or exhaust.
Embodiment as an improvement of the present invention, such as Fig. 1, pressure-reduced and-regulated system 4 control the outlet of flash system 3
Pressure, while steam is supplemented when the secondary steam amount that flash system 3 exports is not able to satisfy air heater front end heating requirements.
Embodiment as an improvement of the present invention, as shown in Figure 1, steam-water separation equipment 5 is installed at steam inlet,
Improve dryness fraction of steam.Steam-water separation equipment 5 includes steam-water separator and hydrophobic station two parts, condensed water and suspension in steam
Moisture be separated under the action of steam-water separation, from the hydrophobic station of 5 bottom of steam-water separation equipment be discharged, the condensation of discharge
Water enters flash system 3.This partial condensation water can not also enter flash system 3 and be discharged to other places.
Embodiment as a further improvement of the present invention, as shown in Figure 1, being installed at the top of steam-water separation equipment 5
