Industrial energy-saving boiler smoke dust purification device convenient for heat energy recovery

Abstract

The invention discloses an industrial energy-saving boiler smoke dust purification device convenient for heat energy recovery. The industrial energy-saving boiler smoke dust purification device comprises a smoke dust purification device, and a filter device and a heat energy recovery device which are connected to the smoke dust purification device, the filter device comprises a mounting tank, and an air inlet pipe and an air outlet pipe are symmetrically mounted on the mounting tank. A mounting frame is fixedly mounted on the inner side wall of the mounting tank, a precise filter screen is fixedly mounted on the inner side wall of the mounting frame, the air inlet pipe and the air outlet pipe are located on the lower side and the upper side of the precise filter screen correspondingly, and a cleaning device matched with the precise filter screen is arranged at the top end of the mounting tank. An inner wall cleaning device is arranged in each heat exchange pipe, and servo motors are started to drive scraping plates to move up and down so that smoke dust accumulated on the inner side walls of the heat exchange pipes can be scraped off, the situation that the smoke dust is accumulated on the inner side walls of the heat exchange pipes, and consequently the heat exchange effect of smoke becomes poor can be prevented, the heat exchange efficiency of the smoke is improved, accordingly, waste of heat energy is avoided, design is reasonable, and the practical effect is good.

Description

technical field [0001] The invention relates to the technical field of industrial energy-saving boilers, in particular to a dust purification device for industrial energy-saving boilers that is convenient for heat energy recovery. Background technique [0002] Industrial energy-saving boiler is a kind of thermal power equipment used for power generation. Since the boiler produces a large amount of smoke when it is working, and the smoke contains harmful substances and smoke, industrial boilers are often equipped with smoke purification devices. In order to avoid The heat energy in the flue gas is wasted. Before purifying the boiler flue gas, the heat energy in the flue gas needs to be recovered. At present, heat exchange tubes are mostly used to recover the heat energy in the flue gas. Due to the high content of smoke in the flue gas, Therefore, smoke and dust are easy to accumulate on the inner wall of the heat exchange tube during heat exchange, which will lead to the grad...
