Owing to contain foreign material such as tar, naphthalene and desulfurization droplet, and make in the process of preheating in the oven gas, very easily cause device to stop up.In the prior art; When preheating device is carried out block clearing, because the inlet that does not have special confession staff to carry out block clearing must use goliath to dismantle whole preheater; This causes scale removal process loaded down with trivial details especially, and the operate as normal to device also affects thus.
Summary of the invention
The structure that the objective of the invention is to solve existing oven gas preheating device is inconvenient to clear up and the problem of easy blocking, and a kind of preheater that is used for the preheating oven gas is provided.
The preheater that is used for the preheating oven gas according to the invention, it comprises hypomere cushion chamber, preheating section and epimere cushion chamber, and it also comprises inspection opening, and said inspection opening is arranged on the sidewall of hypomere cushion chamber.
Also be provided with emissions mouth, oven gas import and steam pipe road junction on the sidewall of said hypomere cushion chamber,
Oven gas import and steam pipe road junction are arranged on the hypomere cushion chamber sidewall relative with inspection opening, the steam pipe road junction below the oven gas import,
The emissions mouth be positioned at inspection opening under.
The bottom of said hypomere cushion chamber is provided with the blowdown swash plate; Place, steam pipe road junction is to hypomere cushion chamber inside and extend upward the formation jet chimney; The internal port of said jet chimney is lower than the oven gas import; The upper surface of blowdown swash plate is a plane inclined, and an end on this plane is positioned at the lower edge of emissions mouth, and the other end on this plane is positioned at the lower edge of the internal port of jet chimney; The lower limb of the internal port of said jet chimney is higher than the lower limb of emissions mouth; The auxiliary swash plate that is provided with in the oven gas import is positioned at the top edge top of the internal port of jet chimney, and should auxiliary swash plate and the blowdown swash plate between form steam channel, steam channel is communicated with jet chimney.
It also comprises the blind plate top cover, and the blind plate top cover covers in the port of epimere cushion chamber, and the blind plate top cover is detachable.
Said inspection opening is a manhole.
The angle of said blowdown swash plate and horizontal plane is between 15 ° to 30 °.
Advantage of the present invention is: the present invention has added inspection opening on the basis of original preheater; Like this can be under the condition of turnover gas valve blank off; Behind the overhaul hole preheater is handled or checked; Thereby solve inspection or handle preheater, must use goliath to dismantle the problem of whole preheater, make the cleaning preheater stop up the operation easily that becomes.Simultaneously, the bottom design of preheater of the present invention the blowdown swash plate, and installed jet chimney additional at section swash plate place, thereby can often clean the blowdown swash plate, prevent that effectively foreign material such as tar from accumulating on the blowdown swash plate, and produce clogging.
