For be it will be apparent that they are considered as being included in the utility model, and related personnel can significantly not depart from this reality
Content described herein is modified or suitably changed with combining on the basis of new content, spirit and scope, realizing and
Using the utility model technology.
In the utility model, unless otherwise stated, Science and Technology noun used herein has this field
The normally understood meaning of technical staff institute.
In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, with reference to specific implementation
The utility model is described in further detail for example.
As depicted in figs. 1 and 2, a kind of electric heating superheated stem boiler provided by the utility model, including boiler body 10,
Steam pipeline 30 and overheat heating tank 40.The first electrothermal tube 11 is equipped in boiler body 10, side is equipped with water inlet, boiler sheet
The top plate of body 10 be equipped with steam collection hood, steam collection hood it is opening down, and outer tilt down extension and with boiler sheet
The side wall of body 10 connects, and steam collection hood includes upper plate 22 and lower plate 21, and lower plate 21 is equipped with several through-holes.Steam pipeline 30
Bottom end be arranged on the top plate of boiler body 10, and communicated with steam collection hood, steam pipeline 30 is internally provided with steam
Separator.Overheat heating tank 40 is fixed on the top surface of boiler body 10, is internally provided with the second electrothermal tube 41, steam pipeline
It is communicated on the inside of 30 upper end and overheat heating tube, one side is equipped with superheated steam and exports 42.
The utility model on the basis of existing steam boiler, increases steam collection hood and steam pipeline 30, and
It is provided with moisture separation device in steam pipeline 30, the through-hole in lower plate 21 is using physical arrangement to the moisture progress in steam
It screens for the first time, postsearch screening is carried out to the steam in boiler body 10 using moisture separation device so that enter overheat heating
The water content of the steam of tank 40 is greatly reduced, and so as to ensure to overheat the high-purity for the superheated steam that heating tank 40 exports, can also keep away
Exempt from overheat heating tank 40 due to water content it is higher caused by corrosion the problems such as, prevent reduced service life, simple in structure, user
Just.
Upper plate 22 and the entrance of steam pipeline 30 are fixed, and the lower part of upper plate 22 and the lower plate 21 is equipped with gap.Due to
Steam collection hood connects with the side wall of boiler body 10, therefore after the steam for being mixed with a part of water droplet is upwardly into through-hole,
The inclination outer of steam collection hood can stop the rising of water droplet, and only steam can enter in steam collection hood at the higher speeds,
And water droplet gradually converges on upper plate 22, and converges downwards under the effect of gravity and finally realized along the side wall of boiler body 10
Reflux is heated, so repeatedly again under the heating of the first electrothermal tube 11.Such structure setting of steam collection hood is simply closed
Reason, is utilized the different characteristics of water droplet and steam and detaches the two.
The bottom of moisture separation device is equipped with hydrops storehouse 33, and the side in hydrops storehouse 33 passes through return pipe 34 and boiler body 10
It communicates.Hydrops storehouse 33 can recycle the water droplet not by moisture separation device, and be detached with the steam of collective low,
Prevent the steam that lower section rises that water droplet is brought into moisture separation device again.
As shown in figure 3, moisture separation device is more helix tubes 31 side by side, the helical angle of each helix tube 31 for 30~
60 °, the bottom of each helix tube 31 is connected with hydrops storehouse 33.The structure setting of multiple helix tubes 31, steam can be divided into it is multigroup,
And due to the structure and shape of helix tube 31, water droplet can be by multiple shock and obstruction, and eventually from helix tube 31
Inner wall condenses, and cannot be introduced into overheat heating tank 40.Helix tube 31 only needs just to screen out water droplet using the structure of itself,
Additional power is not needed to, it is simple in structure, it is easy to maintain.
As shown in figure 4, moisture separation device may also be configured to turbine 32, the entrance of turbine 32 is communicated with hydrops storehouse 33, whirlpool
The rotation of wheel 32 is driven by servo motor.Using turbine 32, according to actual conditions and the reasonable rotating speed that turbine 32 is set can be needed,
Such as the inherent parameters with reference to the sectional area of moisture separation device, turbine 32, so as to which steam and water droplet be detached, using accurate
32 rotating speed of turbine carry out precise manipulation, separative efficiency is high, and can improve the degree of automation, moreover it is possible to be joined according to practical matter
Number adjustment, strong applicability.
The inside of boiler body 10 is equipped with cylindrical inner cavity 13, and the first electrothermal tube 11 is arranged on inner cavity by fixing pipe 12
On 13 side wall, the length direction of the first electrothermal tube 11 is vertical with the length direction of boiler body 10, the length of the second electrothermal tube 41
It is consistent with the length direction for overheating heating tank 40 to spend direction.Cylindrical inner cavity 13 so that the yield of steam meet middle part it is more,
The few form in both sides so as to which the shape with steam collection hood is well agreed with, heats no dead angle, mobility and heat transfer are all more
It is good.
It overheats heating tank 40 and is equipped with temperature sensor 44 and pressure sensor 45, superheated steam outlet 42 is equipped with cut-off
Valve 43, control system send out alarm, and open according to the detected value of temperature sensor 44 and pressure sensor 45 less than preset value
Shut-off valve 43, until the detected value of temperature sensor 44 and pressure sensor 45 is higher than preset value.Since overheat heating tank 40 will
Ensureing the steam of output has certain temperature, and the detected value of temperature sensor 44 and pressure sensor 45 is less than preset value
When, then show that the temperature of steam is inadequate or containing a large amount of water droplets, therefore at this time should opening stop valve 43, suspend steam
It exports, after result qualification to be detected, then exports again.
The utility model, small, gross investment saves, easy to maintenance, substantially reduces labour；It can be widely used for hotel, quotient
Tall building, residential area, the central heating of industrial and mining enterprises and process steam.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
