AI Technical Summary

Technical Problem

In use, the waste heat boiler is directly in use, due to the high-temperature flue gas entering, the flue gas temperature is higher than the dust melting point, causing coking in the boiler, making it difficult to clean the coking and there is a safety risk.

Method used

A waste heat boiler soot anti-coking device is designed, including a filter box, a smoke inlet pipe, a heat sink, an alloy filter and an electric push rod. After the high-temperature flue gas cools through the smoke inlet pipe and heat sink, it enters the filter box and filters the dust through the alloy filter. The electric push rod is used to clean up the dust on the alloy filter.

Benefits of technology

It effectively reduces the temperature of high-temperature flue gas, prevents dust from melting and coking, prevents dust from entering the boiler, avoids coking phenomenon in the boiler, and ensures the normal use of the boiler.

Abstract

The utility model relates to the technical field of waste heat boilers, in particular to a waste heat boiler soot anti-coking device which comprises a filter box and a cover plate, a conveying pipe is installed at one side end of the filter box, a smoke inlet pipe is installed at one side end, away from the conveying pipe, of the filter box, radiating fins distributed in an array mode are installed on the outer surface of the smoke inlet pipe, and the cover plate is installed on the outer surface of the smoke inlet pipe. Two collecting boxes are installed at the lower end of the filter box and communicated with the filter box, the upper end of the filter box is open, the cover plate is installed at the upper end of the filter box, two alloy filter screens are installed at the lower end of the cover plate, and supporting plates which are symmetrically distributed are installed at the upper end of the filter box. A mounting plate is mounted at the upper end of the supporting plate, an electric push rod is mounted at the upper end of the mounting plate, and symmetrically-distributed fixing rods are mounted at the tail end of a piston rod of the electric push rod. The waste heat boiler has the advantages that coking in the waste heat boiler can be prevented, and normal use of the waste heat boiler is guaranteed.
