AI Technical Summary

Technical Problem

In existing boiler generator sets, the recycling rate of soot blowing and hydrophobic water is low, resulting in the failure of effective utilization of energy resources.

Method used

A boiler soot blowing and hydrophobic recovery system is designed, including a soot blowing and hydrophobic confluence box, a reheating accident water spraying heater, a second-stage reheater and a low-temperature reheater imported container. It is transported to the low-temperature reheater imported container by mixing the soot blowing and hydrophobic steam with the second-stage reheater to the low-temperature reheater imported container for recycling.

Benefits of technology

This system simplifies the recovery structure of soot blowing and hydrophobic, improves the energy utilization rate of soot blowing and hydrophobic, reduces heat loss during the recycling process, and enhances the economic benefits of boiler generator sets.

Abstract

The utility model discloses a soot blowing and draining recovery system for a boiler. The soot blowing and draining recovery system comprises a soot blower, a soot blowing and draining combiner box, a reheating accident spray desuperheater, a two-section reheater and a low-temperature reheater inlet header, wherein the first input end of the soot blowing and draining combiner box is communicated with the output end of the soot blower; the first output end of the soot blowing and water draining combiner box is communicated with the first input end of the reheating accident water spraying desuperheater; the second input end of the reheating accident spray desuperheater is connected with the output end of the second-section reheater; and the reheating accident spray desuperheater is connected with the input end of the low-temperature reheater inlet header. The soot blowing drain water and the second-section reheat steam are directly gathered and recycled, the soot blowing drain water is recycled through a recycling pipeline of the second-section reheat steam, namely the second-section reheater, no additional recycling pipeline needs to be arranged, the structure of effective recycling of the soot blowing drain water is simplified, heat loss in the recycling process of the soot blowing drain water is reduced to the maximum extent, and the recycling efficiency of the soot blowing drain water is improved. And the soot blowing hydrophobic recycling effect is improved.
