Description

technical field [0001] The invention relates to the technical field of energy-saving of industrial heating furnaces and boilers, in particular to a leak-free synchronously long telescopic steam soot blower, which is mainly used for steam soot blowing of industrial heating furnace convection chambers, convection tubes and industrial boiler furnace tubes. Background technique [0002] At present, the steam soot blowers used in the convection chamber and convection tube of the industrial heating furnace and the furnace tube of the industrial boiler adopt relatively advanced superheated steam soot blowers. This type of soot blower is driven by the mechanical structure of the variable speed rotating gear, the conduction of the steam is controlled by the quasi-disk and the travel switch, and the high temperature and high pressure superheated steam is ejected through the casing structure to realize the soot blowing of the convection tube bundle, etc. . Its structure is complicated...

AI Technical Summary

Problems solved by technology

Its structure is complex, and air leakage is prone to occur between the sleeves, and the reliability is low

The soot blowing pipe rotating in a full circle is spraying steam, while the convection pipe in the convection chamber is only on the upper and lower sides of the soot blowing pipe. The whole circle of air injection makes the steam spraying to the furnace wall invalid when the soot blowing pipe is turned to the horizontal position. Injection, wasting steam; steam is blown out through the hole, soot blowing efficiency is low

Even the new leak-free synchronous long telescopic steam soot blower (ZL 2008 1 0022001.0) is still using a huge steam soot blowing valve, which has a large number of parts, many manufacturing hours, and many materials used. High, the number of easy failure points is large, and there are safety hazards in failure and maintenance

The mechanism for driving the steam valve is complex, the three-axis output of the reducer, the structure of the gearbox is complex, the driving power is large, and the power consumption is large

Moreover, the function of using the heating pipe cannot be realized. If you want to heat the pipe, you need to add a separate heating pipe system. It occupies a large area, the cost of the device is high, and the consumption of steam is large.

The control cabinet system is huge and consumes a lot of resources
