Flue gas treatment and recycling device for oil and gas fired boiler and use method of flue gas treatment and recycling device

Abstract

The fuel oil and gas boiler flue gas treatment and recycling device comprises a boiler body, a gas outlet pipe is arranged at the top end of the boiler body, a chemical adding mechanism is arranged at one end of the gas outlet pipe, and a waste heat recycling mechanism is arranged on one side of the chemical adding mechanism; the waste heat recovery mechanism comprises a foam glass heat preservation box, a polyurethane heat preservation box, a first ventilation pipe, a second ventilation pipe, a first connecting pipe, three second connecting pipes, a plurality of air outlet holes and ceramic, a box cover is arranged at the top end of the foam glass heat preservation box, and a heating mechanism is arranged in an inner cavity of the foam glass heat preservation box; the heating mechanism comprises a heating box, a plurality of partition plates and a plurality of positioning blocks. By means of the arrangement mode that the waste heat recovery mechanism and the heating mechanism are matched, smoke with waste heat flows towards the outer wall of the heating box, heat conduction of the outer wall of the heating box is uniform through ceramics, the heating box can conduct preheating treatment on objects, and recycling of resources is improved.

Description

technical field [0001] The invention relates to the field of treatment and reuse of flue gas from a fuel-fired gas boiler, in particular to a treatment and reuse device for flue gas from a fuel-fired gas boiler and a method for using the same. Background technique [0002] Oil-fired gas boilers, as the name suggests, refer to boilers that can both fuel oil and gas. There was no such dual-fuel boiler before, because the burner was either fuel oil or gas, and there was no dual-fuel burner. With the rapid development of thermal energy equipment in the world, Europe Some countries in the world began to produce and sell oil-fired gas burners, and the organic combination of dual-fuel burners and boilers gave birth to oil-fired gas boilers. [0003] The flue gas steam used by the existing oil-fired gas-fired boilers is generally discharged directly after purification by the manufacturer, resulting in the waste heat of the flue gas steam that cannot be reused, resulting in a certain...
