Connecting method with powder dust separating device, vertical type invert exhaust-heating boiler and exhaust pipeline

Abstract

A connecting method of a dust separation device, a vertical inverted waste-heat boiler and an exhaust piping, aids in dispensing with an independent settling chamber in the dust separation device and the vertical inverted waste-heat boiler(3) by virtue of integration of the dust device and the waste-heat boiler(3), so as to decrease area and obtain reduction of concentrated wear of the waste-heat boiler(3), effectively solving the wear problem of heating surface of the waste-heat boiler(3) which ensures a long term safety operation.

Description

Technical field: [0001] The invention relates to the field of waste heat utilization of medium and low temperature waste gas, and is especially suitable for producing steam by using waste heat of medium and low temperature waste gas in production lines of cement, steel, building materials, metallurgy, petroleum, chemical industry, ceramics, etc. Connection method of separation device, vertical inverted waste heat boiler and waste gas pipeline. technical background: [0002] At present, the waste heat of waste gas from the kiln head and tail of the new dry process cement production line is used to generate steam through the waste heat boiler for pure low-temperature waste heat power generation. The feature of this technology is that a waste heat boiler is installed at the kiln head and kiln tail of each cement production line. The waste gas from the kiln head first enters the settling chamber through the waste gas pipeline, and then the settled waste gas enters from the top ...

AI Technical Summary

Problems solved by technology

The exhaust gas pipeline rises and falls many times, the pipeline is long, and the exhaust gas resistance is large, which even causes the kiln head fan to be overloaded, affecting the normal operation of the cement kiln
