A cyclone dust collector recovering waste heat

Abstract

A cyclone dust collector recovering waste heat is disclosed. The cyclone dust collector comprises a gas inlet, a gas outlet, a gas outlet pipe, a heat exchange plate, a cold-water inlet, a hot-water outlet and a connecting part. The gas inlet is disposed at a side of the dust collector. The top of the dust collector is provided with the gas outlet. The gas outlet pipe is disposed below the gas outlet and is a long barrel with a horn-shape pipe opening. The inner wall of the gas outlet pipe is provided with the heat exchange plate. The heat exchange plate is provided with the cold-water inlet and the hot-water outlet. The heat exchange plate comprises each independent module. The two independent modules are communicated through the connecting part. The heat exchange plate is disposed at the inner wall of the gas outlet pipe so that the heat exchange plate is only contacted with dedusted purified gas, thus prolonging the service lifetime of the heat exchange plate. The gas outlet pipe is the long barrel with the horn-shape pipe opening, and therefore the area of the heat exchange plate is increased, and the horn-shape pipe opening facilitates entering of the purified gas into the gas outlet pipe. The heat exchange plate is set to be independent modules and the modules are communicated through the connecting part, thus facilitating maintenance.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to a cyclone dust collector for recovering waste heat. Background technique [0002] Most of the smoke and dust discharged from boilers and kilns still have a lot of heat energy, and cyclone dust collectors are often used as primary dust removal equipment for raw flue gas. Most of the existing cyclone dust collectors do not have waste heat recovery devices, resulting in waste heat in the flue gas It is a waste of waste. At present, some cyclone dust collectors are equipped with waste heat recovery devices. For example, a heat exchange plate is installed in the outlet pipe, which hinders the discharge of flue gas after dust removal. The heat exchange plate is used as the outlet pipe, but because there are many dust impurities in the original flue gas, when the original flue gas spirals downward through the air inlet, the smoke and dust will adhere to the heat exchange plate, whi...

Problems solved by technology

[0003] The present invention is aimed at the problems existing in the above-mentioned products, and provides a cyclone dust collector for recovering waste heat, which solves the problem that most of the existing cyclone dust collectors in the above-mentioned products do not have waste heat recovery devices, resulting in waste of waste heat in the flue gas. Currently, some cyclones The dust collector is equipped with a waste heat recovery device, for example, a heat exchange plate is installed in the air outlet pipe, which hinders the discharge of the flue gas after dust removal, and the heat exchange plate is curled into a gas outlet pipe, and the heat exchange plate is used as an air outlet pipe When used, smoke and dust will adhere to the heat exchange plate, which will increase the maintenance cost and affect the life of the heat exchange plate.
