Energy-saving system with automatic ash removal function of horizontal type gas heat exchanger

Abstract

The invention discloses an energy-saving system with an automatic ash removal function of a horizontal type gas heat exchanger, and belongs to the technical field of energy conservation and emission reduction. The energy-saving system comprises a steel structure supporting frame, the horizontal type energy-saving heat exchanger is borne on the upper part of the steel structure supporting frame, aninner masonry heat preservation layer is built on the inner wall of the horizontal type energy-saving heat exchanger, a sound wave ash blower is installed on the upper part of the horizontal type energy-saving heat exchanger, the input end of the horizontal type energy-saving heat exchanger is connected with a smoke inlet pipeline, the output end of the horizontal energy-saving heat exchanger isconnected with a smoke outlet pipeline, and a coal gas monitoring instrument is installed on the smoke outlet pipeline; and ash deposition bins are arranged at the bottom of the horizontal type energy-saving heat exchanger at intervals. According to the energy-saving system with the automatic ash removal function of the horizontal type gas heat exchanger, high-pressure blowing is carried out through the sound wave ash blower at the top, ash on the pipe wall of the heat exchanger can be blown off at any time and collected in a centralized mode, thus the service life of the horizontal type energy-saving heat exchanger is prolonged, the heat exchange efficiency is greatly improved due to the fact that ash does not exist on the pipe wall, and meanwhile dust particles in smoke are reduced.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, and more specifically relates to an energy-saving system for an automatic ash-removing horizontal gas heat exchanger. Background technique [0002] In modern blast furnace ironmaking and lime kiln production, high-temperature flue gas will be discharged, which also contains more impurities. With the rapid development of my country's economy and the continuous improvement of people's living standards in the past few decades, the emission of global warming and pollutant particles has increased sharply. An important factor for the further improvement of people's living and health standards. Therefore, the flue gas produced from blast furnace ironmaking and lime kiln not only has a high discharge temperature, but also contains a certain amount of dust. With the expansion and transformation of blast furnaces in iron and steel enterprises, the original form of heat exchang...

Problems solved by technology

With the expansion and transformation of blast furnaces in iron and steel enterprises, the original form of heat exchangers cannot meet the technological requirements of enterprises due to the limitations of existing site conditions, and the design concept of recovery of exhausted flue gas waste heat needs to be innovated
