Boiler discharged smoke waste heat recycling system with flue for removing smoke

Abstract

The invention relates to a boiler discharged smoke waste heat recycling system with a flue for removing smoke. The boiler discharged smoke waste heat recycling system with the flue for removing smoke comprises a water pump and a controller, wherein a first pipeline is mounted at a water outlet of the water pump and is connected to an inlet of an energy economizer; an outlet of the energy economizer communicates with a water inlet of a boiler through a third pipeline; a second pipeline is further arranged on the first pipeline in a branched manner and directly communicates with the third pipeline; an opening and closing valve is mounted on the second pipeline; a first thermometer and a first pressure gauge are mounted on the first pipeline; a second thermometer and a second pressure gauge are mounted on the third pipeline; an input end of the controller is connected with the first thermometer; an output end of the controller is connected with the energy economizer; the controller controls power of the energy economizer according to temperature signals detected by the first thermometer; the energy economizer comprises a smoke channel mounted on a support and a serpentine pipe in the smoke channel; and smoke removing plates are mounted between two adjacent vertical sections of the serpentine pipe.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler waste heat recovery and utilization system. Background technique [0002] The gas-fired hot water boiler in the prior art has a low recycling rate, and the economizer has poor controllability to the water temperature, which requires regular adjustment and troublesome operation; the flue gas is directly discharged to the outside, because the flue gas will be mixed with Some dust, direct discharge affects the environment. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the present invention provides a boiler exhaust waste heat recovery and utilization system with flue removal, and the present invention adopts the following scheme: [0004] A system for recovery and utilization of waste heat from boiler exhaust with flue removal, including a water pump, a first pipeline is installed at the water outlet of the water pum...
