Cyclone wet dust extraction type energy-saving coal-fired boiler

Abstract

The invention discloses a cyclone wet dust extraction type energy-saving coal-fired boiler. The cyclone wet dust extraction type energy-saving coal-fired boiler comprises a coal-fired boiler body, a smoke exhaust pipe and a washing bin. A bearing plate is horizontally arranged inside the coal-fired boiler body. Both the two sides of the bearing plate are hinged to the parts, on the two sides, of the inner surface wall of the coal-fired boiler body through connecting plates. The top of the coal-fired boiler body communicates with the washing bin through the smoke exhaust pipe. A draught fan isfixedly connected with the side, away from the smoke exhaust pipe, of the washing bin. According to the cyclone wet dust extraction type energy-saving coal-fired boiler, because the fire coal bearingplate is hinged to the inner surface wall of the coal-fired boiler body through the connecting plates, the bearing plate is in a movable state, the bearing plate can generate corresponding vibration because of the vibration effect of a vibration motor, the fire coal on the bearing plate can evenly scatter through the vibration action of the bearing plate, the effective contact area between the fire coal and oxygen is increased so that the fire coal burns sufficiently and completely, waste of resources is avoided, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention relates to the technical field of coal-fired boilers, in particular to a cyclone wet-process dedusting energy-saving coal-fired boiler. Background technique [0002] Coal-fired boiler refers to the coal that is burned as fuel. After the heat of coal is converted, steam or hot water is generated, but not all the heat is effectively converted, and some of the heat is consumed reactively, so there is an efficiency problem, generally larger Boiler efficiency is higher, between 60% and 80%. [0003] However, the existing cyclone wet dust removal coal-fired boilers still have some shortcomings. On the one hand, the coal piled up inside the boiler generally cannot be completely burned, resulting in a waste of energy. , the dust removal effect is not ideal, and a large number of inhalable particles remaining in the smoke cannot be removed. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in ...
