Due to using above-mentioned technical proposal, the beneficial effects of the invention are as follows：
The steam generating equipment that the present invention is provided includes steam generator body, multi-stage heat exchanger and water pipe water lev el control system
System, wherein steam generator body use stainless steel waterpipe, and the external diameter of stainless steel waterpipe is 10-20mm, and pipe thickness is 1.2-
2mm, compared with existing irony water pipe, substantially reduces caliber and wall thickness, and caliber is small, and tube wall is thin, and heat transfer speed is fast, quick heating,
Because the water being heated in single stainless steel waterpipe is few, so that it is especially fast to heat up, and because caliber is small, the stainless steel water that can be set
Pipe quantity is more, increases the quantity of stainless steel waterpipe being heated simultaneously, it is ensured that have enough water while being heated, and wherein every not
Rust molten steel pipe has sufficiently large heating surface area, and heat transfer speed is fast, hence in so that producing the speed of steam very fast, produces first
Raw available pressure steam is only needed 20 seconds, intermittently reuses generation available pressure steam by only needing 5 seconds, produces the speed of steam
Degree is significantly larger than the steam production rate of existing steam generating equipment, and steam is not clean contaminated, can be widely applied to
All conglomeraties such as food processing, beverage, medicine and electronic product machining.
Multi-stage heat exchanger is set on flue of the invention, and snakelike heat exchange tube is stainless steel tube, and small volume is corrosion-resistant, is easy to
In flue, the snakelike heat exchange tube of heat exchanger is provided with fin so that the heat exchange area of snakelike heat exchange tube is very big, has
Effect absorbs flue gas heat, flue-gas temperature is discharged up to 50-60 degrees Celsius, well below the discharge flue gas of existing steam generating equipment
Water after heat exchange heats up in temperature, snakelike heat exchange tube is entered into collecting chamber, improves the water temperature in collecting chamber, is conducive to improving and is produced
The speed of raw steam, compared with directly cold water is added in collecting chamber, saves a large amount of energy needed required for heating cold water,
And inner walls are provided with insulating, heat is effectively prevented to be scattered and disappeared from housing, housing outer surface temperature is Celsius up to 20-30
Degree so that this steam generating equipment heat scatters and disappears less, and the thermal efficiency is up to 95-98%, and the thermal efficiency of existing steam generating equipment
Highest is only capable of reaching 60%, the thermal efficiency due to this equipment with superelevation, and it is single backhaul heating, structure letter to set stainless steel waterpipe
Single, small volume, working service is convenient, low cost.
Water pipe water level control system of the invention, on the liquid level tube between the height of marine riser 1/3 be provided with bottom limit level meter, middle limit
Liquid level gauge and upper limit level meter, meet this equipment because steam production rate is fast, and corresponding water consumption is fast, need to add water frequently
Ask, when water level is less than middle limit liquid level gauge, PLC controls water pump to being added water in collecting chamber, is reached when adding water to water level
Limit liquid level gauge when, PLC control water pump stop add water, when due to equipment fault or other reasonses cause water level be less than lower limit
During liquid level gauge, PLC control combustor is out of service, while control water pump operation to be added water, now PLC control
Acoustic-optic alarm signal an alert processed, people are to check equipment or take other emergency measures for warning, avoid the occurrence of completely
Equipment dry combustion method situation, and water level in precise control water pipe is in more than middle limit liquid level gauge water level, it is ensured that can fast and safely produce
Raw steam.
Because the volume of collecting chamber of the invention and the volume sum of stainless steel waterpipe are less than 30L, small volume is dangerous
Small, security is good, is not belonging to special equipment, and Operation and Maintenance is simple, and does not need specialized operations personnel, using and maintenance cost
It is low.
Because stainless steel waterpipe and collecting chamber and steam chest are welded to connect and form seal-weld, and sealing reinforcement is set
Plate, sealing reinforcing plate and stainless steel waterpipe and collecting chamber and steam chest are all welded to connect and form seal-weld, set twice
Seal-weld, strengthens stainless steel waterpipe and the sealing property between collecting chamber and steam chest, and the sealing met under pressure condition will
Ask.
Supporting plate is reinforced due to setting, it is to avoid stainless steel waterpipe deforms in thermal histories, it is ensured that the structure of equipment
Intensity and sealing property.
Because housing is cylindrical shape, collecting chamber, steam chest, sealing reinforcing plate and reinforces supporting plate and be annular and coaxial
Set, stainless steel waterpipe is distributed in a ring centered on the axial direction of collecting chamber and steam chest, and stainless steel waterpipe layer distributed,
Combustor is installed on collecting chamber top, is easy to stainless steel waterpipe to be heated, and equipment overall volume is small, occupies little space, and is easy to
Install.
Due to leaving gap, the extension plane of the snakelike heat exchange tube of heat exchanger and the extension side of flue between adjacent heat exchange device
To vertical, flue gas resistance is reduced.
