Vapor and water circulating type high-efficiency boiler bladder
Patent of the present invention relates to a kind of boiler bladder, particularly a kind of vapor and water circulating type high-efficiency boiler bladder.
The boiler of selling in the market and using mostly is and prolongs that the out-of-date methods of attacking for many years make, and directly uses heating agent in the boiler stove fire heating boiler.This method efficient is not high, time-consuming, the thermal efficiency is low.
The purpose of patent of the present invention provides a kind of scientific and reasonable for structure for boiler.High efficiency, a kind of boiler bladder that save time, the thermal efficiency is high.
The purpose of patent of the present invention is achieved in that it comprises poly-fire pot, flue water inlet pipe, furnace outer wall, cambered surface on the flue, fire tube, flue outlet pipe.
It is characterized in that: flue is up big and down small, adopts many fire tubes to pass from flue, is forming liquid storage cylinder between cambered surface on furnace outer wall and fire tube, poly-fire pot and the flue, and liquid storage cylinder communicates with flue water inlet pipe and flue outlet pipe.When using patent of the present invention, no matter be from the water inlet of flue water inlet pipe, from the water outlet of courage outlet pipe, still from the water inlet of flue outlet pipe, from the water outlet of flue water inlet pipe, flue can both be efficiently to the boiler transfer of heat.Save time, thermal efficiency height.
Below in conjunction with accompanying drawing in detail, patent of the present invention is described in detail.
Fig. 1 is the structural representation of patent of the present invention
As shown in the figure, the boiler inner structure of patent of the present invention is such, boiler casing 1 and boiler inner wall 2 form annular liquid storage cylinder, liquid storage cylinder communicates with flue water inlet pipe 3 and flue outlet pipe 4, the still transverse tube 11 that above flue, communicates with liquid storage cylinder, transverse tube 11 is relative with fire tube 8, and the up big and down small flue that more helps of flue absorbs heat.
When injecting liquid in the flue, when the plane surpasses flue outlet pipe upper limb on the liquid, will produce air seal between cambered surface on flue outlet pipe upper limb and the flue.Form certain space 10.And along with the rising of flue temperature, the continuous cementing of oxygen meeting in the space is recycled water and takes away in water, thereby the space of sealing can form vacuum.The latent heat that intensifies of general material all is very big, under the vacuum state material to intensify temperature very low, when temperature was not high, its evaporation that just comes to life absorbed a large amount of carbonated drink latent heat simultaneously.
The course of work of the present invention is to realize like this, along with the rising of flue temperature, the liquid in the flue liquid storage cylinder will absorb a large amount of latent heats of vaporization, and evaporates, after circulating fluid is seen the liquid that absorbs a large amount of latent heats of vaporization and steam off, entered new cryogenic liquid in the flue again.Cryogenic liquid is heated again absorbs a large amount of latent heats of vaporization evaporations, simultaneously the steam release heat of condensing in water.Go round and begin again, finally realize the work of time-saving and efficiency.
This kind heat transfer type is more much bigger than the heat that conduction, convection current, radiation transmit, and from the waste heat that fire tube passes, can continue as the upper lateral tube heating, and final combustion gas reaches energy-efficient, environmental protection.
