Arrangement structure of shock wave ash blower of vertical waste heat boiler

Abstract

The invention provides an arrangement structure of a shock wave ash blower of a vertical waste heat boiler. The arrangement structure can solve the problem that an existing arrangement structure of the nozzle-type shock wave ash blower is narrow in shock wave space and poor in ash blowing effect, and therefore high heat transfer efficiency of the heating surfaces of the boiler can be effectively guaranteed. A row of shock wave ash blowing tubes transversely penetrating through the chamber of the vertical waste heat boiler are horizontally arranged above each stage of heating surface of the vertical waste heat boiler, each shock wave ash blowing tube is independently connected with a shock wave pulse generator, each shock wave pulse generator is installed on a side plate of a box of the vertical waste heat boiler through an installation support, and the wall of each shock wave ash blowing tube is provided with a plurality of downward ash blowing holes uniformly in the length direction.

Description

Technical field [0001] The invention relates to the technical field of boiler ash removal, in particular to the technical field of ash removal of a vertical waste heat boiler, in particular to the arrangement structure of a vertical waste heat boiler shock soot blower. Background technique [0002] The ash accumulation on the heating surface of the vertical waste heat boiler is one of the main factors that affect the safe operation of the boiler and the boiler output, and the shock wave soot blowing system can effectively remove the ash accumulation on the heating surface of the boiler, so that the heating surface maintains good heat transfer efficiency. Traditional vertical waste heat boilers use nozzle shock soot blowers, which are generally arranged on both sides of the furnace wall of the vertical waste heat boiler, see figure 1 , The nozzles 10 on both sides blow soot in a horizontal inward manner, which has the defects that the shock wave space is narrow and the dust accumul...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems, the present invention provides the arrangement structure of the shock wave soot blower of the vertical waste heat boiler, which can solve the problems of narrow shock wave space and poor soot blowing effect existing in the arrangement structure of the existing nozzle type shock wave soot cleaner, thereby Effectively ensure good heat transfer efficiency on the heating surface of the boiler
