Abstract

Provided is a smoke dust waste-heat utilization and dust removing device of a low-capacity boiler. A boiler smoke vent is connected with a water heating tank, a steel pipe inner enables high-temperature smoke to pass through, water inside the water heating tank is heated, and when the boiler needs water supplement, a water pump enables high-temperature water to be added inside the boiler. Due to the fact that the high-temperature water enters the boiler, the heating time of the boiler is shortened, fuel is saved, and the smoke with the temperature being lowered by the water tank is delivered into a water mist dust remover by a centrifugal fan. Smoke dust is slowed down by being pulled back by a plurality of stages of baffles, and meanwhile the smoke dust is washed through dense water mist, dust particles sink into the water by trapping of the water mist, dust mud is accumulated on the bottom and is cleaned regularly by a spiral discharging machine. According to the smoke dust waste-heat utilization and dust removing device of the low-capacity boiler, the supplementary water of the boiler is heated, and meanwhile the temperature of the smoke dust is lowered. Therefore hazardous substances such as sulfur dioxide, nitrogen oxides and carbon dioxide in the smoke dust are completely filtered, and dust removing and cleaning efficiency is improved. The smoke dust waste-heat utilization and dust removing device of the lower-capacity boiler is simple in structure, capable of saving energy, easy to maintain, low in implementation cost and convenient to operate and use.
