Abstract

The invention relates to a flue-smoke-removal-type smoke condensation waste heat recycling system. The flue-smoke-removal-type smoke condensation waste heat recycling system comprises a water pump, wherein a first pipeline is installed at a water outlet of a water pump, the first pipeline is connected to an inlet of an energy saver, an outlet of the energy saver is communicated with a water inlet of a boiler by virtue of a third pipeline, the first pipeline is also branched to form a second pipeline, the second pipeline is directly communicated with the third pipeline, and a switch valve is installed on the second pipeline; the first pipeline is provided with a first thermometer and a first pressure gauge; the third pipeline is provided with a second thermometer and a second pressure gauge, and the flue-smoke-removal-type smoke condensation waste heat recycling system also comprises a controller, wherein an input end of the controller is connected with the first thermometer, an output end is connected with the energy saver, and the controller controls the power of the energy saver according to a temperature signal detected by the first thermometer.

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 flue gas removal system for recovery and utilization of waste heat from condensation of flue gas. The present invention adopts the following scheme: [0004] A flue gas removal flue gas condensation waste heat recovery system, including a water pump, a first pipeline is installed at the water outlet of the water pump, th...
