Abstract
The utility model relates to a descending tube, in particular to a long-distance descending tube of a flame-tube type waste heat boiler. The long-distance tube of the flame-tube type waste heat boiler comprises a middle tube. An upper straight tube is arranged on the upper portion of the middle tube. A lower straight tube is arranged on the lower portion of the middle tube. The middle tube is fixedly connected with the upper straight tube through a 45-degree bend. The middle tube is fixedly connected with the lower straight tube through a 90-degree bend. An adapter tube which is communicated with the lower straight tube is arranged at the bottom of the lower straight tube. The length of the middle tube is 2133mm. The length of the upper straight tube is 1602mm, and the length of the lower straight tube is 932mm. An expansion angle between the upper straight tube and the middle tube is 135 degrees. The long-distance descending tube of the flame-tube type waste heat boiler is simple in structure and good in using effect.
Description
Technical field
The utility model is a kind of down-comer, and particularly a kind of length of fire tube waste heat boiler is apart from down-comer.
Background technology
Waste heat boiler of the prior art, complex structure, result of use is poor.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of length of fire tube waste heat boiler simple in structure apart from down-comer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of length of fire tube waste heat boiler is apart from down-comer, comprise intervalve, the top of described intervalve is provided with straight tube, the bottom of described intervalve is provided with lower straighttube, described intervalve and last straight tube are fixedly connected by one eighth bend, described intervalve and lower straighttube are fixedly connected by 90 degree elbows, the bottom of described lower straighttube is provided with and is attached thereto logical adapter, the length of described intervalve is 2133mm, the described length that goes up straight tube is 1602mm, the length of described lower straighttube is 932mm, and the described opening angle of going up straight tube and intervalve is 135 degree.
Therefore, the length of the fire tube waste heat boiler that the utility model provides is apart from down-comer, and is simple in structure, and result of use is good.
